5Housing Stock and Roof Types in Presidio

On most jobs, where Presidio buildings have been re-roofed twice, the next job is a tear-off regardless of what the owner would prefer. San Francisco County is no different.

Additions and conversions are common in Presidio, and the joint between the original roof and the newer section is where nearly all leaks begin. San Francisco County is no different.

6Pricing a Presidio Roof Honestly

1What Sits on Most Presidio Roofs

Multi-unit buildings in Presidio usually need a low-slope system and a maintenance plan rather than a one-off repair. On most jobs, streets in Presidio that were built out together tend to call for roofs together, which is why one re-roof more often than not brings three more on the same block. This holds across San Francisco County. Roof pitch across Presidio varies enough that the right material on one street is the wrong one two blocks away.

3Choosing a Presidio Roofing Contractor

Written scope, itemised price and a written warranty are the minimum on any Presidio project. Put simply, inspect that the Presidio crew doing the work is employed by the company quoting it.

Partial claims on a Presidio roof are common and should be priced as repairs rather than inflated into replacements.

Underlayment choice is what decides it more than covering choice on a Presidio tile roof, because that is the layer doing the waterproofing. Metal has grown in Presidio for its lifespan and reflectivity, though the fixing system has to allow for movement or the panels telegraph every fastener. It is the same story on most Presidio streets. Tile is widespread across Presidio, and the tile will outlive the underlayment beneath it by decades — which is what catches property owners out. Mixing materials across a Presidio roof is fine provided each section gets the system it needs and the transitions are flashed properly.

In practice, flashing at the wall junction is checked first on any Presidio inspection, because that is where nearly all ceiling stains originate. Infrared scanning on a Presidio commercial roof locates wet insulation that no visual inspection would find.
In practice, concrete tile suits Presidio buildings designed for the weight; laying it on framing that was not is a structural question earliest. Underlayment choice counts more than covering choice on a Presidio tile roof, since that is the layer doing the waterproofing. As a rule, synthetic composite has become a credible option in Presidio where the look of slate or shake is wanted without the weight or the fire risk.
