Excelsior roofing work in Excelsior, San Francisco County — inspection, repair, replacement and coatings, quoted in writing and permitted where the work requires it.
1Excelsior Permit Requirements
In practice, fire-zone properties around Excelsior carry assembly requirements that the permit will look over against. Inspection scheduling in Excelsior adds a day or two to the programme and should be in the contractor's timeline from the start. Worth knowing before you sign anything. Solar removal and reset on a Excelsior project can need its own electrical permit alongside the roofing one. Codes change, and the San Francisco Department of Building Inspection applies the version current on the day the permit issues, which is one reason a Excelsior estimate should state the assembly being laid. Commercial work in Excelsior generally involves more review than residential and a longer lead time. This holds across San Francisco County.
Put simply, infrared scanning on a Excelsior commercial roof locates wet insulation that no visual inspection would find. Moisture readings matter on Excelsior low-slope roof coverings. Coating over wet insulation seals the problem in rather than solving it. Worth knowing before you sign anything. A Excelsior roof is inspected from the attic as well as the roof surface; half the evidence is underneath.
2What the Weather Does to a Excelsior Roof
Expansion and contraction loosens fixings on Excelsior roof coverings long ahead of the material itself gives out. As a rule, roofs in Excelsior bake. Asphalt loses its oils, membranes lose their plasticisers, and sealant shrinks back from every flashing. Dry offshore winds reach Excelsior through autumn, lifting shingle tabs and ridge caps in the direction roofs are least lapped to resist. Realistically, summer heat is the main ageing force on a Excelsior roof. Surface temperatures run far above the air reading, day after day, for months. Afternoon sun on a west-facing Excelsior slope ages that side years ahead of the rest of the roof. Tile underlayment in Excelsior dries out and goes brittle while the tile above it still looks new from the street.
Realistically, ask any Excelsior roofer what happens if the deck is worse than expected, and get the answer before the covering comes off. That is as true in Excelsior as anywhere in San Francisco County. Ask a Excelsior contractor for recent addresses nearby and go and look at the work from the street. A contractor who explains why a Excelsior roof failed is more use than one who only quotes to replace it.
3The Excelsior Maintenance Year
Checking the attic after the earliest heavy rain in Excelsior finds leaks while they are still stains rather than damage. Keeping a dated maintenance file on a Excelsior property pays for itself the earliest time a claim is questioned. As a rule, clearing the Excelsior gutters in late autumn prevents most of the damage the first storm would otherwise cause. Drainage is the cheapest maintenance on any Excelsior building — blocked outlets cause more damage here than the storms themselves. Moss on a shaded Excelsior slope should be treated rather than scraped, since scraping takes the granules with it.
In practice, solar removal and reset on a Excelsior job can need its own electrical permit alongside the roofing one. That is as true in Excelsior as anywhere in San Francisco County. Commercial work in Excelsior usually involves more review than residential and a longer lead time. Historic districts near Excelsior may restrict covering type and colour, which is worth confirming before materials are ordered.
4Which System Fits a Excelsior Property
Lightweight tile gives Excelsior owners the look without the structural upgrade older framing would otherwise need. That is as true in Excelsior as anywhere in San Francisco County. Underlayment choice matters more than covering choice on a Excelsior tile roof, because that is the layer doing the waterproofing. Flat and low-slope sections in Excelsior need a membrane or a coating system, not shingle laid at a pitch it was never designed for. That is as true in Excelsior as anywhere in San Francisco County. Realistically, architectural shingle outperforms three-tab on a Excelsior roof for a modest extra cost and a meaningfully longer working life. Put simply, coatings suit Excelsior buildings with a sound deck and a tired surface — they buy seasons, but they do not fix water already trapped in the insulation. It is the same story on most Excelsior streets. TPO and modified bitumen both work on Excelsior low-slope roofs, and the choice in most cases comes down to detailing rather than the sheet. Worth knowing before you sign anything.
Financing makes sense on a Excelsior roof that is actively failing; it rarely makes sense on one with years of life left. We see it on Excelsior roofs every week. A Excelsior roof quoted without anyone looking in the attic is a quote based on half the information. Put simply, deck replacement on a Excelsior job is unknown until the tear-off, which is why it belongs in the contract as a per-sheet rate.
5Understanding Your Excelsior Estimate
Financing makes sense on a Excelsior roof that is actively failing; it rarely makes sense on one with years of life left. Material choice changes a Excelsior roof covering budget less than most owners expect; labour and complexity dominate. Realistically, warranty terms affect the real cost of a Excelsior roof covering more than the headline figure does. As a rule, square footage is only half the cost of a Excelsior roof; pitch, access and layer count move the number as much. A Excelsior estimate worth reading itemises tear-off, disposal, underlayment, covering, flashing, permit and clean-up separately.
Solar removal and reset on a Excelsior job can require its own electrical permit alongside the roofing one. We see it on Excelsior roofs every week. Structural the project on a Excelsior roof triggers a separate review beyond the roofing permit itself. Inspection scheduling in Excelsior adds a day or two to the programme and should be in the contractor's timeline from the start. That is as true in Excelsior as anywhere in San Francisco County.
6Finding the Problem on a Excelsior Roof
Put simply, flashing at the wall junction is checked first on any Excelsior inspection, because that is where most ceiling stains originate. San Francisco County is no different. Realistically, a proper Excelsior inspection starts at the flashings, not the field. Chimneys, vents, skylights and the swamp cooler curb fail long before the covering does. Lifting a few tiles in two or three places is the only way to date the underlayment on a Excelsior tile roof, and it takes fifteen minutes. A Excelsior roof is inspected from the attic as well as the roof surface; half the evidence is underneath. Deck fastener pull-through is checked on older Excelsior roofs, since the sheathing commonly fails ahead of the shingle does.
In practice, the San Francisco Department of Building Inspection handles the paperwork for roofing the job in Excelsior, and a licensed contractor pulls it as part of the work rather than leaving it to the homeowner. On most jobs, reroofing over existing layers in Excelsior is limited by code, and the layer count is checked at inspection. San Francisco County is no different. The permit record for a Excelsior property is public, which is how a buyer's inspector checks the roof was done properly.
7What Sits on Most Excelsior Roofs
Roof age across Excelsior clusters around the decades when the area filled in, which means whole streets reach the end of their covering within a few seasons of each other. San Francisco County is no different. Streets in Excelsior that were built out together tend to require roof coverings together, which is why one re-roof often brings three more on the same block. Original decking on older Excelsior homes is frequently skip sheathing, which changes what can be laid over it. As a rule, older Excelsior buildings frequently sit on their second or third covering, and the layer count matters more than the age when planning the next one. A Excelsior property often carries more than one roof covering type — a pitched main house in one material and a flatter garage or addition in another. Where Excelsior buildings have been re-roofed twice, the next job is a tear-off regardless of what the property owner would prefer.
Realistically, summer heat is the main ageing force on a Excelsior roof covering. Surface temperatures run far above the air reading, day after day, for months. We see it on Excelsior roofs every week. As a rule, a light-coloured covering in Excelsior measurably lowers attic temperature and takes load off the air conditioning. Tile underlayment in Excelsior dries out and goes brittle while the tile above it still looks new from the street.
8Working With Your Adjuster in Excelsior
Code upgrade cover decides whether a Excelsior claim pays for bringing the assembly current or only for like-for-like. Put simply, supplements are normal on Excelsior claims once the covering is off and the deck is visible, and they should be raised with evidence rather than argued later. Policies covering Excelsior properties generally pay for sudden harm and not for age, so the report has to separate the two clearly. Put simply, partial claims on a Excelsior roof are common and should be priced as repairs rather than inflated into replacements. Emergency tarping on a Excelsior roof covering is normally covered, and receipts should be kept for it. Put simply, deductibles on Excelsior policies vary enough that the claim decision changes case by case.
In practice, where Excelsior buildings have been re-roofed twice, the next job is a tear-off regardless of what the owner would prefer. As a rule, garage and patio roofs in Excelsior are frequently lower slope than the house and need an entirely different system. As a rule, roof pitch across Excelsior varies enough that the right material on one street is the wrong one two blocks away.
9Choosing a Excelsior Roofing Contractor
Two warranties apply on Excelsior work: the manufacturer's on the material and the installer's on the workmanship. Ask for both. Payment schedules on Excelsior the job should track progress, never run ahead of it. San Francisco County is no different. In practice, the Excelsior contractor who tells you a make good will do, when a repair will do, is the one worth calling back. On most jobs, ask a Excelsior contractor for recent addresses nearby and go and look at the work from the street. Worth knowing before you sign anything. Local experience matters in Excelsior because the failure modes here are heat, wind load and drainage rather than snow and ice. Check the CSLB licence number in advance of any Excelsior roofer starts, and confirm liability cover and workers' compensation are current.
Mixing materials across a Excelsior roof is fine provided each section gets the system it needs and the transitions are flashed properly. Composition shingle is the most common covering in Excelsior and the cheapest to renew, but it is also the first to show UV damage. San Francisco County is no different. On most jobs, architectural shingle outperforms three-tab on a Excelsior roof for a modest extra cost and a meaningfully longer life. That is as true in Excelsior as anywhere in San Francisco County.

1How We Inspect a Excelsior Roof
Lifting a few tiles in two or three places is the only way to date the underlayment on a Excelsior tile roof, and it takes fifteen minutes. It is the same story on most Excelsior streets. As a rule, infrared scanning on a Excelsior commercial roof locates wet insulation that no visual inspection would find. In practice, a Excelsior inspection should end with a written report and photographs, not a verbal summary and a price. That is as true in Excelsior as anywhere in San Francisco County. Flashing at the wall junction is checked soonest on any Excelsior inspection, given that that is where most ceiling stains originate. Core samples settle the argument on a Excelsior low-slope roof when moisture is suspected but not visible. It is the same story on most Excelsior streets. On most jobs, valley condition is the single best indicator of how a Excelsior roof has been maintained.
Put simply, sealant is the earliest casualty in Excelsior; it shrinks, cracks and pulls away from every penetration within a few seasons. In practice, thermal cycling does the harm in Excelsior — hot afternoons, cool nights, and materials expanding and contracting against their fixings all year. On most jobs, debris in Excelsior valleys holds what little water arrives against the covering, which is where rot usually starts.
2Understanding Your Excelsior Estimate
In practice, a Excelsior roof quoted without anyone looking in the attic is a quote based on half the information. On most jobs, phasing a large Excelsior building across two seasons is more often than not cheaper than financing the whole job at once. A Excelsior quote that comes in far below the others is usually missing the flashing, the permit or the disposal. Financing makes sense on a Excelsior roof that is actively failing; it rarely makes sense on one with years of working life left. Square footage is only half the cost of a Excelsior roof; pitch, access and layer count move the number as much. Worth knowing before you sign anything. As a rule, deck replacement on a Excelsior work is unknown until the tear-off, which is why it belongs in the contract as a per-sheet rate. Worth knowing before you sign anything.
The Excelsior contractor who tells you a repair will do, when a repair will do, is the one worth calling back. A good Excelsior roofer will talk you out of the project you do not need, which is the clearest signal there is. Two warranties apply on Excelsior the job: the manufacturer's on the material and the installer's on the workmanship. Ask for both. We see it on Excelsior roofs every week.
3Choosing a Covering in Excelsior
On most jobs, metal has grown in Excelsior for its lifespan and reflectivity, though the fixing system has to allow for movement or the panels telegraph every fastener. Synthetic composite has become a credible option in Excelsior where the look of slate or shake is wanted without the weight or the fire risk. Lightweight tile gives Excelsior property owners the look without the structural upgrade older framing would otherwise need. Underlayment choice matters more than covering choice on a Excelsior tile roof, because that is the layer doing the waterproofing. Cool-rated coverings are worth specifying in Excelsior even where code does not require them. Realistically, architectural shingle outperforms three-tab on a Excelsior roof for a modest extra cost and a meaningfully longer life.
We photograph every elevation on a Excelsior job so the documented estimate can be read against what is actually up there. We check ventilation on every Excelsior job, because a roof that cannot breathe will not reach its rated life. A proper Excelsior inspection starts at the flashings, not the field. Chimneys, vents, skylights and the swamp cooler curb give out long in advance of the covering does.
4Hiring Well in Excelsior
Payment schedules on Excelsior work should track progress, never run ahead of it. We see it on Excelsior roofs every week. Local experience matters in Excelsior because the failure modes here are heat, wind and drainage rather than snow and ice. In practice, documented scope, documented price and a written warranty are the minimum on any Excelsior job. As a rule, a Excelsior roofing company who will not put the assembly in writing is not quoting the same project as the one who will. San Francisco County is no different. A contractor who explains why a Excelsior roof covering failed is more use than one who only quotes to replace it. Realistically, manufacturer certification matters on Excelsior jobs because it is what makes the material warranty enforceable.
Put simply, we inspect ventilation on every Excelsior job, given that a roof covering that cannot breathe will not reach its rated working life. It is the same story on most Excelsior streets. Put simply, a Excelsior inspection should end with a written report and photographs, not a verbal summary and a price. A proper Excelsior inspection starts at the flashings, not the field. Chimneys, vents, skylights and the swamp cooler curb let go long before the covering does.
5Excelsior Roofing and Your Policy
In practice, a Excelsior adjuster works from the scope in front of them, which is why the contractor's report has to be thorough. We see it on Excelsior roofs every week. In practice, matching provisions in a policy matter on Excelsior tile roofs where the original profile is discontinued. This holds across San Francisco County. We do not advise filing a Excelsior claim where the damage is clearly age, because a declined claim stays on the record. Worth knowing before you sign anything. Actual cash value and replacement cost behave very differently on an older Excelsior roof covering, and the policy wording decides which applies. Deductibles on Excelsior policies vary enough that the claim decision changes case by case.
Afternoon sun on a west-facing Excelsior slope ages that side years ahead of the rest of the roof covering. Sealant is the first casualty in Excelsior; it shrinks, cracks and pulls away from every penetration within a few seasons. Worth knowing before you sign anything. Tile underlayment in Excelsior dries out and goes brittle while the tile above it still looks new from the street. This holds across San Francisco County.
6What the Weather Does to a Excelsior Roof
As a rule, debris in Excelsior valleys holds what little moisture arrives against the covering, which is where rot as a rule starts. Low-slope sections in Excelsior hold heat worst, which is why coatings and reflective membranes pay for themselves here. It is the same story on most Excelsior streets. Excelsior gets its rain in a handful of concentrated winter storms, which means drainage that sat dry collecting debris has to move everything at once. Worth knowing before you sign anything. As a rule, sealant is the first casualty in Excelsior; it shrinks, cracks and pulls away from every penetration within a few seasons. Put simply, dry offshore winds reach Excelsior through autumn, lifting shingle tabs and ridge caps in the direction roof coverings are least lapped to resist. Worth knowing before you sign anything.
Resealing penetrations on a Excelsior roof covering every few years is the cheapest the project anyone will ever do on the building. Realistically, clearing the Excelsior gutters in late autumn prevents most of the damage the first storm would otherwise cause. A Excelsior roof covering with working drainage outlasts an identical roof covering without it by years. San Francisco County is no different.
7Permits and Inspections in Excelsior
Full replacements in Excelsior generally require a permit through the San Francisco Department of Building Inspection, with an inspection once the work is finished. Solar removal and reset on a Excelsior job can require its own electrical permit alongside the roofing one. San Francisco County is no different.

A Excelsior roof with working drainage outlasts an identical roof covering without it by years. Put simply, a maintenance record on a Excelsior roof also helps at claim time, because it shows the failure was sudden rather than neglected. Worth knowing before you sign anything. Drainage is the cheapest maintenance on any Excelsior building — blocked outlets cause more damage here than the storms themselves. Two visits a year keeps a Excelsior roof covering honest: clear the valleys and gutters ahead of the rains, and check the flashings once past the first heavy storm.
Square footage is only half the cost of a Excelsior roof; pitch, access and layer count move the number as much. As a rule, material choice changes a Excelsior roof covering budget less than most owners expect; labour and complexity dominate. We see it on Excelsior roofs every week. Financing makes sense on a Excelsior roof that is actively failing; it rarely makes sense on one with seasons of life left.
9Housing Stock and Roof Types in Excelsior
Housing stock in Excelsior runs across several eras, and each one brings its own roof. What sits above the ceiling in most cases tells you when the building went up. A Excelsior property frequently carries more than one roof type — a pitched main house in one material and a flatter garage or addition in another. Where Excelsior buildings have been re-roofed twice, the next work is a tear-off regardless of what the owner would prefer. It is the same story on most Excelsior streets. Second-storey additions in Excelsior create a junction between old and new roof that requires proper flashing rather than sealant. Worth knowing before you sign anything. Older Excelsior buildings frequently sit on their second or third covering, and the layer count matters more than the age when planning the next one. As a rule, multi-unit buildings in Excelsior usually need a low-slope system and a maintenance plan rather than a one-off make good.
Put simply, skylight seals on Excelsior roofs want checking annually, as they fail quietly and drip into the ceiling cavity. A maintenance record on a Excelsior roof also helps at claim time, because it shows the failure was sudden rather than neglected. On most jobs, flashings at the chimney on an older Excelsior house generally call for attention well in advance of the covering does.

1The Excelsior Maintenance Year
In practice, a maintenance record on a Excelsior roof covering also helps at claim time, since it shows the failure was sudden rather than neglected. This holds across San Francisco County. Keeping a dated maintenance file on a Excelsior property pays for itself the earliest time a claim is questioned. We see it on Excelsior roofs every week. As a rule, flashings at the chimney on an older Excelsior house usually need attention well before the covering does. Loose ridge caps on a Excelsior roof are a five-minute fix ahead of the winds and a much larger one once past. Trimming back branches over a Excelsior roof removes the debris that holds moisture against the covering and shortens its life. Realistically, resealing penetrations on a Excelsior roof every few seasons is the cheapest work anyone will ever do on the building.
Cost on a Excelsior roof comes down to size, pitch, how many layers come off, and what the deck looks like underneath. We see it on Excelsior roofs every week. Deck replacement on a Excelsior job is unknown until the tear-off, which is why it belongs in the contract as a per-sheet rate. Material choice changes a Excelsior roof budget less than most owners expect; labour and complexity dominate.
2The Excelsior Inspection, Step by Step
Flashing at the wall junction is checked first on any Excelsior inspection, since that is where most ceiling stains originate. Worth knowing before you sign anything. Realistically, drone access on steep or fragile Excelsior roofs gets the detail without anyone walking a covering that cannot take it. San Francisco County is no different. We photograph every elevation on a Excelsior job so the written estimate can be read against what is actually up there. In practice, we check the deck from inside the attic on every Excelsior job. Daylight through the sheathing tells you more than anything visible from the driveway. Deck fastener pull-through is checked on older Excelsior roof coverings, since the sheathing often gives out before the shingle does. Granule loss in the gutters is the earliest honest signal on a Excelsior shingle roof covering, and it shows up years in advance of a ceiling stain does.
As a rule, underlayment choice is what decides it more than covering choice on a Excelsior tile roof, given that that is the layer doing the waterproofing. Lightweight tile gives Excelsior owners the look without the structural upgrade older framing would otherwise need. Mixing materials across a Excelsior roof is fine provided each section gets the system it needs and the transitions are flashed properly.
3Excelsior Roofing Budgets
A Excelsior quote that comes in far below the others is in most cases missing the flashing, the permit or the disposal. Put simply, deck replacement on a Excelsior work is unknown until the tear-off, which is why it belongs in the contract as a per-sheet rate. Realistically, the variable line on any Excelsior quote is deck repair, and it should be priced per sheet in writing rather than hidden in an allowance. Repair makes sense on a Excelsior roof with life left and a localised failure, and nowhere else. That is as true in Excelsior as anywhere in San Francisco County. Financing makes sense on a Excelsior roof covering that is actively failing; it rarely makes sense on one with years of working life left. Worth knowing before you sign anything.
Valley condition is the single best indicator of how a Excelsior roof covering has been maintained. We photograph every elevation on a Excelsior project so the written estimate can be read against what is actually up there. Moisture readings matter on Excelsior low-slope roofs. Coating over wet insulation seals the problem in rather than solving it. That is as true in Excelsior as anywhere in San Francisco County.
4What the Weather Does to a Excelsior Roof
Excelsior gets its rain in a handful of concentrated winter storms, which means drainage that sat dry collecting debris has to move everything at once. As a rule, attic ventilation on a Excelsior property is not optional — trapped heat cooks the covering from underneath. Put simply, roof surface temperatures in Excelsior routinely run well above the air reading, and every material on the roof feels it. Worth knowing before you sign anything. Roof coverings in Excelsior bake. Asphalt loses its oils, membranes lose their plasticisers, and sealant shrinks back from every flashing. This holds across San Francisco County. Tile underlayment in Excelsior dries out and goes brittle while the tile above it still looks new from the street.

5Storm Damage Claims in Excelsior
In practice, a Excelsior adjuster works from the scope in front of them, which is why the contractor's report has to be thorough. We see it on Excelsior roofs every week. Most Excelsior claims that fail do so since the damage was cleaned up or patched before anyone photographed it. Wind and storm harm on a Excelsior roof covering is covered where it is documented; wear is not covered anywhere. On most jobs, actual cash value and replacement cost behave very differently on an older Excelsior roof, and the policy wording decides which applies. We see it on Excelsior roofs every week. On most jobs, we do not advise filing a Excelsior claim where the damage is clearly age, because a declined claim stays on the record. Put simply, we the job alongside the adjuster on Excelsior claims rather than around them, which keeps the scope honest and the timeline shorter.
Manufacturer certification is what decides it on Excelsior jobs because it is what makes the material warranty enforceable. Local references beat national brand badges on any Excelsior roofing decision. San Francisco County is no different. Payment schedules on Excelsior work should track progress, never run ahead of it.
6Excelsior Permit Requirements
the San Francisco Department of Building Inspection handles the paperwork for roofing work in Excelsior, and a licensed roofing company pulls it as part of the job rather than leaving it to the owner. On most jobs, permit fees in Excelsior are a small part of the project and a large part of what protects the owner at resale. Put simply, a permitted Excelsior re-roof leaves a record that supports any later insurance claim on the same roof. This holds across San Francisco County. Put simply, work in Excelsior is inspected as well as permitted — the San Francisco Department of Building Inspection signs off the finished assembly, not just the application. Structural work on a Excelsior roof covering triggers a separate review beyond the roofing permit itself. Full replacements in Excelsior generally require a permit through the San Francisco Department of Building Inspection, with an inspection once the the job is finished.
Valley condition is the single best indicator of how a Excelsior roof has been maintained. On most jobs, deck fastener pull-through is checked on older Excelsior roof coverings, since the sheathing frequently gives out in advance of the shingle does. A correct Excelsior inspection starts at the flashings, not the field. Chimneys, vents, skylights and the swamp cooler curb fail long ahead of the covering does. That is as true in Excelsior as anywhere in San Francisco County.
7Housing Stock and Roof Types in Excelsior
Older Excelsior buildings frequently sit on their second or third covering, and the layer count matters more than the age when planning the next one. In practice, multi-unit buildings in Excelsior generally call for a low-slope system and a maintenance plan rather than a one-off repair. On most jobs, garage and patio roofs in Excelsior are frequently lower slope than the house and need an entirely different system. On most jobs, streets in Excelsior that were built out together tend to need roofs together, which is why one re-roof more often than not brings three more on the same block. Realistically, original decking on older Excelsior homes is often skip sheathing, which changes what can be laid over it.
Repair makes sense on a Excelsior roof with service life left and a localised failure, and nowhere else. Low-priced Excelsior quotes generally skip the flashing. That is where the money is saved and where the next leak arrives. That is as true in Excelsior as anywhere in San Francisco County. In practice, seasonal demand in Excelsior affects scheduling more than price, but booking ahead of the rains helps both.
8Roofing Materials That Suit Excelsior
Mixing materials across a Excelsior roof is fine provided each section gets the system it needs and the transitions are flashed properly. Reclaimed tile can be matched on Excelsior heritage roofs, but the underlayment beneath it should always be new. Synthetic composite has become a credible option in Excelsior where the look of slate or shake is wanted without the weight or the fire risk. As a rule, architectural shingle outperforms three-tab on a Excelsior roof for a modest extra cost and a meaningfully longer life. This holds across San Francisco County. Silicone coatings hold up well on Excelsior roofs that pond slightly, where acrylic would not. San Francisco County is no different.
Core samples settle the argument on a Excelsior low-slope roof when water is suspected but not visible. Infrared scanning on a Excelsior commercial roof locates wet insulation that no visual inspection would find. We photograph every elevation on a Excelsior job so the written estimate can be read against what is actually up there.
9Hiring Well in Excelsior
Check that the Excelsior crew doing the work is employed by the company quoting it. This holds across San Francisco County. A contractor who explains why a Excelsior roof covering failed is more use than one who only quotes to replace it. Two warranties apply on Excelsior the job: the manufacturer's on the material and the installer's on the workmanship. Ask for both. This holds across San Francisco County. On most jobs, clean-up and magnetic nail sweep should be in the Excelsior contract, not assumed. In practice, documented scope, written price and a documented warranty are the minimum on any Excelsior job.
Roof coverings in Excelsior bake. Asphalt loses its oils, membranes lose their plasticisers, and sealant shrinks back from every flashing. Expansion and contraction loosens fixings on Excelsior roof coverings long before the material itself gives out. Attic ventilation on a Excelsior property is not optional — trapped heat cooks the covering from underneath. San Francisco County is no different.
