1Why Potrero Hill Roofs Age the Way They Do

Thermal cycling does the harm in Potrero Hill — hot afternoons, cool nights, and materials expanding and contracting against their fixings all year. Expansion and contraction loosens fixings on Potrero Hill roof coverings long before the material itself gives out. Attic temperatures in Potrero Hill drive shingle working life as much as the weather above does, which is why ventilation is what decides it more here than the brochure suggests. Tile underlayment in Potrero Hill dries out and goes brittle while the tile above it still looks new from the street. It is the same story on most Potrero Hill streets. Low-slope sections in Potrero Hill hold heat worst, which is why coatings and reflective membranes pay for themselves here. Put simply, summer high temperatures is the main ageing force on a Potrero Hill roof. Surface temperatures run far above the air reading, day after day, for months.

Payment schedules on Potrero Hill the project should track progress, never run ahead of it. Written scope, written price and a written warranty are the minimum on any Potrero Hill job.
