LOW-SLOPE ROOFS

Ask any crew that works San Diego County and they will tell you the same thing - whatever fails first on these roofs fails at the edges. 138 miles southeast means a free inspection costs you nothing but an hour.
We are in Imperial Beach, Chula Vista and Otay Mesa constantly, and the housing stock is much the same.
Leaks found in summer cost a fraction of the same leak found in February. 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.
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 San Ysidro tightens fast, and emergency work costs more than planned work.
The questions we hear most in San Ysidro are about price, timing and whether a repair will hold. We answer all three before you commit, and we put the answers in writing.
Synthetic underlayment goes down over the whole deck, not just the valleys.

We work the same streets in Imperial Beach, Chula Vista and Otay Mesa, so crews know the area and its roofs.
We would rather be on your roof in September than during the first atmospheric river. We will tell you if the roof has five years left, because that is also useful to know.
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.
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.

CLEAR ANSWERS. LOCAL EXPERTISE.
SAN YSIDRO, CA TORCH DOWN ROOFING
For most flat and low-slope roofs in San Ysidro, yes. Two plies of modified bitumen with heat-welded seams handle ponding and UV far better than patching.
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.
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.
Installed to spec, twenty years and up, with a manufacturer warranty of 10, 20 or 25 years depending on the system.
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.
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.
Most single-family roofs in San Ysidro are done in two to four days once materials are on site. Larger or steeper roofs, or jobs with deck repairs, run longer and we say so up front.
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.
