Material choice changes a Tenderloin roof budget less than most owners expect; labour and complexity dominate. That is as true in Tenderloin as anywhere in San Francisco County. On most jobs, square footage is only half the cost of a Tenderloin roof covering; pitch, access and layer count move the number as much. The variable line on any Tenderloin quote is deck repair, and it should be priced per sheet in writing rather than hidden in an allowance.

3Why Tenderloin Roofs Age the Way They Do

5Finding the Problem on a Tenderloin Roof
A Tenderloin roof is inspected from the attic as well as the roof surface; half the evidence is underneath. San Francisco County is no different. We photograph every elevation on a Tenderloin job so the documented estimate can be read against what is actually up there. We check ventilation on every Tenderloin job, because a roof that cannot breathe will not reach its rated service life.

2What to Ask a Tenderloin Roofer
A Tenderloin contractor who will not put the assembly in writing is not quoting the same job as the one who will.

Two warranties apply on Tenderloin work: the manufacturer's on the material and the installer's on the workmanship. Ask for both.

Seasonal demand in Tenderloin affects scheduling more than price, but booking ahead of the rains helps both.

That is as true in Tenderloin as anywhere in San Francisco County.
Realistically, thermal cycling does the damage in Tenderloin — hot afternoons, cool nights, and materials expanding and contracting against their fixings all year. 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. Roofs in Tenderloin bake. Asphalt loses its oils, membranes lose their plasticisers, and sealant shrinks back from every flashing.
