LOW-SLOPE ROOFS

There is nothing abstract about a Diamond Heights roof: nothing dries quickly here, so a small leak stays wet. From the shop it is a 336-mile run northwest to Diamond Heights, so emergencies get a same-day answer.
Crews rotate through Glen Park, Noe Valley and Twin Peaks, so nothing about these streets is new to us.
We would rather find the problem in the dry months and fix it on a schedule. If a repair solves it, we quote the repair instead of selling a replacement.
Soft decking gets replaced, not covered - we quote a sheet count and show you the bad bays.
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.
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.
Cheap work shows up at the details: a flashing sealed instead of replaced, a vent reused because it was quicker, decking covered because nobody wanted the conversation. Those are the roofs we get called back to in two winters.
Drip edge and starter course get installed properly - that is half the wind resistance.
We quote Diamond Heights roofs off what the roof is actually doing, and whatever fails first on these roofs fails at the edges. We cover Diamond Heights from about 336 miles northwest, close enough for emergency calls.
Jobs in Glen Park, Noe Valley and Twin Peaks run alongside this one most weeks.
Summer is for planned work; winter is for emergencies nobody planned. No pressure, no same-day-only discount, no hard close.
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.
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.
The questions we hear most in Diamond Heights are about price, timing and whether a repair will hold. We answer all three before you commit, and we put the answers in writing.

DIAMOND HEIGHTS, CA TORCH DOWN ROOFING
Cost depends on the size and pitch of the roof, the material you choose, how many layers come off and what the deck looks like underneath. We inspect the Diamond Heights property, measure it and put a detailed number in writing before anything is booked.
Installed to spec, twenty years and up, with a manufacturer warranty of 10, 20 or 25 years depending on the system.
For most flat and low-slope roofs in Diamond Heights, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
We do. Permits and inspections go through the local building department and we handle the paperwork rather than leaving it to you.

Yes. The inspection and the written estimate are free, including a second opinion if you already have a quote in hand. We photograph what we find and walk you through it.
A modified bitumen base sheet torched to the deck or cover board, with a white Polyfresko cap sheet over it. The white surface reflects heat instead of holding it.
