Torrance Roof Pros provides professional flat & low-slope roofing in Torrance, CA for residential and commercial properties across the South Bay. Nothing built to drain is truly flat. The design minimum is a quarter of an inch of fall per foot, and the reason so many rear additions, garages and carports in this city leak is that they were framed at half of that, or at nothing at all.
So the first question on a low-slope job is where the water is meant to go, and the second is whether it can actually get there. We shoot the plane with a level, find the low spot, and check whether the outlet sits at it. When the plane still holds a puddle after a hose test, adding fall with tapered polyiso belongs in the scope rather than in a change order we mention in week two.
For membrane choice we default to 60-mil white single-ply, mechanically attached at the perimeter and heat-welded at every seam, on the typical two hundred to eight hundred square foot residential addition. It goes on cold with no torch anywhere near your house, the welds are testable with a probe while the crew is still standing there, and one crew dries it in the same day.
Where the surface takes real foot traffic, an air-conditioning platform, a roof deck, a ladder route used every month, we specify two-ply SBS modified bitumen with a granulated cap instead. It is thicker, considerably more forgiving of abuse from other trades, and easier for anyone to patch by hand years later without a hot-air welder on site. We also build a proper walkway pad on the route other trades will use anyway.
The perimeter is where these roofs are won or lost. A membrane needs a positive termination: gravel stop or coping over a solid nailer, a proper drip edge at the eave, base flashing carried a minimum of eight inches up any wall, and the wall covering counterflashed down over it rather than a bead of sealant smeared along the top edge.
We will not install a membrane and leave a shingle plane draining onto it with no transition detail. That junction, steeper roof dumping onto flat roof, is the leak we get called about most across the South Bay, and it needs a welded or soldered pan sized for the volume arriving from above, not a lap and a tube of mastic. We price that pan as part of the roof.
Our licensed and insured team brings the right materials and equipment to every job — 2-in-12 minimum shingle slope, double underlayment lapped 19 inches, 60-mil mechanically attached TPO, two-ply SBS modified bitumen cap sheet, mechanically-seamed double-lock metal panels, self-adhered high-temperature underlayment — and backs the work with a written workmanship warranty. We serve Torrance and nearby communities including Redondo Beach, Lomita, Gardena, Carson.

Materials, equipment and how we do flat & low-slope roofing
The difference between flat & low-slope roofing that lasts and flat & low-slope roofing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with 2-in-12 minimum shingle slope, double underlayment lapped 19 inches, 60-mil mechanically attached TPO, two-ply SBS modified bitumen cap sheet, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Torrance job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in the South Bay means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
