1The Tenderloin Inspection, Step by Step
In practice, deck fastener pull-through is checked on older Tenderloin roof coverings, since the sheathing more often than not fails before the shingle does. San Francisco County is no different.

Seasonal demand in Tenderloin affects scheduling more than price, but booking ahead of the rains helps both. This holds across San Francisco County. A Tenderloin quote that comes in far below the others is as a rule missing the flashing, the permit or the disposal. We see it on Tenderloin roofs every week.

Most roofs in Tenderloin fall into three groups: original coverings near the end of their life, replacements from the last two decades, and low-slope sections added later. As a rule, additions and conversions are common in Tenderloin, and the joint between the original roof and the newer section is where the majority of leaks begin.
3The Conditions a Tenderloin Roof Works Against
Expansion and contraction loosens fixings on Tenderloin roofs long before the material itself gives out. Put simply, tenderloin gets its rain in a handful of concentrated winter storms, which means drainage that sat dry collecting debris has to move everything at once. Tile underlayment in Tenderloin dries out and goes brittle while the tile above it still looks new from the street. Sealant is the first casualty in Tenderloin; it shrinks, cracks and pulls away from every penetration within a few seasons. That is as true in Tenderloin as anywhere in San Francisco County.

Low-slope sections in Tenderloin hold high temperatures worst, which is why coatings and reflective membranes pay for themselves here. We see it on Tenderloin roofs every week.
A Tenderloin roof is inspected from the attic as well as the roof surface; half the evidence is underneath. On most jobs, we look over the deck from inside the attic on every Tenderloin job. Daylight through the sheathing tells you more than anything visible from the driveway. San Francisco County is no different. As a rule, infrared scanning on a Tenderloin commercial roof covering locates wet insulation that no visual inspection would find.
4Material Options for Tenderloin Roofs
TPO and modified bitumen both the project on Tenderloin low-slope roofs, and the choice in most cases comes down to detailing rather than the sheet. Synthetic composite has become a credible option in Tenderloin where the look of slate or shake is wanted without the weight or the fire risk. On most jobs, tile is widespread across Tenderloin, and the tile will outlive the underlayment beneath it by decades — which is what catches homeowners out. Flat and low-slope sections in Tenderloin need a membrane or a coating system, not shingle laid at a pitch it was never designed for. On most jobs, lightweight tile gives Tenderloin property owners the look without the structural upgrade older framing would otherwise call for. San Francisco County is no different.
Warranty terms affect the real cost of a Tenderloin roof covering more than the headline figure does. Put simply, phasing a large Tenderloin building across two seasons is often cheaper than financing the whole job at once. It is the same story on most Tenderloin streets.

Emergency tarping on a Tenderloin roof covering is normally covered, and receipts should be kept for it. It is the same story on most Tenderloin streets. Actual cash value and replacement cost behave very differently on an older Tenderloin roof, and the policy wording decides which applies. A Tenderloin adjuster works from the scope in front of them, which is why the contractor's report has to be thorough. This holds across San Francisco County. Wind and storm damage on a Tenderloin roof is covered where it is documented; wear is not covered anywhere. Nearly all Tenderloin claims that give out do so because the damage was cleaned up or patched in advance of anyone photographed it.

Put simply, two visits a year keeps a Tenderloin roof honest: clear the valleys and gutters before the rains, and check the flashings after the first heavy storm. It is the same story on most Tenderloin streets. As a rule, moss on a shaded Tenderloin slope should be treated rather than scraped, since scraping takes the granules with it. It is the same story on most Tenderloin streets.
Deck replacement on a Tenderloin job is unknown until the tear-off, which is why it belongs in the contract as a per-sheet rate. Seasonal demand in Tenderloin affects scheduling more than price, but booking ahead of the rains helps both. We see it on Tenderloin roofs every week. In practice, phasing a large Tenderloin building across two seasons is more often than not cheaper than financing the whole job at once. San Francisco County is no different.
