LOW-SLOPE ROOFS

If you own property in Diamond Heights, the local conditions decide what your roof needs: wind off the water drives rain sideways into laps that face it. 336 miles northwest means a free inspection costs you nothing but an hour.
We work the same streets in Glen Park, Noe Valley and Twin Peaks, so crews know the area and its roofs.
A roof opened in winter costs more and risks more, so we plan around the forecast. Expect photos, a measured scope and a number you can compare against anyone else.
Drip edge and starter course get installed properly - that is half the wind resistance.
Dry-season work is cheaper and safer, because the whole job happens on dry decking. Once the first storm is on the ten-day forecast the calendar in Diamond Heights tightens fast, and emergency work costs more than planned work.
A roof is a system. The membrane or shingle gets the attention, but the underlayment, the fasteners, the edge metal and the ventilation decide whether it reaches its warranty.

Nothing is left on the lawn overnight, and the dumpster goes when the job ends.
We quote Diamond Heights roofs off what the roof is actually doing, and wind off the water drives rain sideways into laps that face it. Diamond Heights is around 336 miles northwest of the shop, which keeps scheduling simple.
Neighbouring work in Glen Park, Noe Valley and Twin Peaks means materials are already staged nearby.
We would rather find the problem in the dry months and fix it on a schedule. We will tell you if the Diamond Heights roof has years left in it rather than sell you a new one.
We do not use subcontract crews we have never met. The people on your Diamond Heights roof are the people we train, and they carry our workers' compensation.
Before we quote we check the deck, the ventilation, the flashings and the drainage. Three of those four are invisible from the ground, and all four decide how long the roof lasts.
Dry-season work is cheaper and safer, because the whole job happens on dry decking. Once the first storm is on the ten-day forecast the calendar in Diamond Heights tightens fast, and emergency work costs more than planned work.
