LOW-SLOPE ROOFS

We work on Dogpatch roofs most weeks, and the pattern is consistent: fog drip keeps the north side wet long enough to grow moss. The shop is about 335 miles northwest, which is why we can be out the same day.
Crews rotate through Potrero Hill, Mission Bay and Bayview, so the drive is routine.
Summer is for planned work; winter is for emergencies nobody planned. You get photos, measurements and a plain explanation before any work is booked.
Fascia and rafter tails get checked while the edge is open.
When the crew leaves, the debris leaves with them: magnet passes morning and evening, gutters cleared, driveway swept. You get photos of the finished work and the warranty paperwork registered in your name.
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.
Price follows the roof, not a rate card: access, pitch, material, how many layers come off and what the deck looks like underneath. We measure in person, show you photos and put the number in writing before anything is booked.
Ridge venting goes in where the roof line allows it, with proper intake at the eaves.
There is nothing abstract about a Dogpatch roof: sea air corrodes anything unprotected and keeps north slopes damp. From the shop it is a 335-mile run northwest to Dogpatch, so emergencies get a same-day answer.
Potrero Hill, Mission Bay and Bayview are on the same route, which keeps follow-ups easy.
The first big storm books out the whole trade, so earlier is cheaper. Everything starts with a free inspection and a written number for your Dogpatch property.
The questions we hear most in Dogpatch are about price, timing and whether a repair will hold. We answer all three before you commit, and we put the answers in writing.
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.
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.
Everything below is the same crew, same city, same free inspection.

DOGPATCH, CA TORCH DOWN ROOFING
We carry the permits and insurance for hot work, run a fire watch and keep extinguishers on the roof. Where open flame is not appropriate we quote a cold-applied or coating system instead.
For most flat and low-slope roofs in Dogpatch, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
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.
Yes. Panels are detached and reset on a schedule that matches the roofing crew, and the penetrations are re-flashed properly when they go back.

Installed to spec, twenty years and up, with a manufacturer warranty of 10, 20 or 25 years depending on the system.
Tear-off debris leaves the same day. Driveways are swept, gutters cleared and a magnet pass runs morning and evening, which matters on a street with kids and pets.
