Mobile Roof Pros provides professional flat & low-slope roofing in Mobile, AL for residential and commercial properties across the central Gulf Coast. Low slope is where rainfall volume becomes an engineering problem instead of a detailing one. Water that a steep roof sheds in seconds sits on a shallow plane and finds every seam, so drainage design comes before any conversation about material.
The first question on a low-slope section is where the water goes and how quickly. We measure the plane, find the low points with a level and a hose, and design positive drainage to a scupper, an internal drain or a free edge with enough fall that nothing stands after 48 hours. Tapered polyisocyanurate builds that fall where the framing never provided it, and a quarter inch per foot is our minimum on new work.
Then the membrane. Self-adhered SBS-modified bitumen in a base and cap configuration is our default on residential porches, additions and shallow rear planes, because it is redundant by design and tolerates the foot traffic a porch roof gets. Single-ply TPO or EPDM makes better sense on larger, cleaner planes with fewer penetrations, where a heat-welded or taped seam beats a torch or a mopped lap on every measure that matters.
The mistake we correct most often is shingles on a slope that cannot carry them. Below three in twelve, asphalt shingles are relying on the underlayment to be the roof, and below two in twelve they should not be there at all. Builders and previous owners run them out over a shallow porch anyway, and the stained porch ceiling below is usually the proof of it.
Ponding is not a cosmetic complaint. Standing water at the low end of a shallow plane adds dead load, degrades the membrane where it sits, and turns an occasional pinhole leak into a continuous one. Any low-slope section we quote comes with a drainage sketch showing where water leaves, and if it cannot leave, we say the deck has to be re-pitched.
Terminations get metal, not sealant. Edge metal is fastened and stripped in, wall terminations get counterflashing in a reglet or a termination bar with a serviceable sealant joint, and every penetration gets a formed flashing and a clamping ring. Sealant is a maintenance item with a service life measured in a handful of years, so we never let a roof depend on it to stay dry.
Our licensed and insured team brings the right materials and equipment to every job — ASTM D1970 self-adhered underlayment, sealed roof decks with taped panel seams, open 26-gauge W-valley metal, kick-out flashing at roof-to-wall terminations, six-inch K-style aluminum gutter with three-by-four downspouts, ring-shank fasteners at six and twelve inch spacing — and backs the work with a written workmanship warranty. We serve Mobile and nearby communities including Prichard, Tillmans Corner, Saraland, Daphne.

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 ASTM D1970 self-adhered underlayment, sealed roof decks with taped panel seams, open 26-gauge W-valley metal, kick-out flashing at roof-to-wall terminations, 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 Mobile 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 central Gulf Coast means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.
