Portland ME Roof Pros provides professional flat & low-slope roofing in Portland, ME for residential and commercial properties across southern Maine. The thing that sets the price of a low-slope roof in Portland is not its area. It is the length of wall it dies into. A twelve-by-sixteen membrane with three sides against painted clapboard costs more to detail than a membrane twice its size sitting out in the open.
That is because a low-slope roof does not end at the membrane. It ends at a termination, and a proper termination means counterflashing let into the wall above it, either into a reglet or under the siding course, so water arriving down the wall lands on top of the flashing rather than behind it. Sealant along the top edge of a membrane is not a termination. It is a countdown.
On a pre-1978 building, letting that flashing in means removing or lifting painted siding along the entire run. Measured as surface area, a thirty-foot wall termination is comfortably past the exterior threshold on its own, which is why we quote perimeter and field as separate quantities and why our number for a small rear roof sometimes reads high next to a competitor who intends to caulk it.
For the membrane itself we favor fully-adhered EPDM on residential work and mechanically-attached or adhered TPO on larger decks. Both are cold-applied. We do not torch modified bitumen on these buildings, and it is worth knowing that open-flame burning or torching of painted surfaces is a prohibited work practice on pre-1978 housing regardless of how careful the operator is.
Drainage is the other honest conversation. Many of these roofs were built dead flat and have settled into a low spot that ponds for days. Membrane over standing water fails early no matter whose logo is on it, so we quote tapered insulation to build fall toward the outlet rather than pretend a new sheet solves it. Where the budget will not carry taper, we say the roof is a ten-year roof and price it as one.
And sometimes we recommend spending less. A sound single-ply with one bad seam and a failed drain does not need replacing. It needs the seam welded, the drain rebuilt with a proper clamping ring, and then to be left alone. A roof that only wants a repair should only get a repair, and we would rather be called back in eight years than in eight months.
Our licensed and insured team brings the right materials and equipment to every job — self-adhered ice barrier membrane at eaves and in every valley, over-fascia intake vents slotted through sheathing instead of painted soffit, board sheathing overlay panel where plank gaps outrun a fastener's grip, concealed-clip standing seam panel in a Kynar finish, counterflashing let into a raked mortar joint and repointed, soldered stainless liners fitted inside built-in cornice troughs — and backs the work with a written workmanship warranty. We serve Portland and nearby communities including South Portland, Westbrook, Scarborough, Gorham.

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 self-adhered ice barrier membrane at eaves and in every valley, over-fascia intake vents slotted through sheathing instead of painted soffit, board sheathing overlay panel where plank gaps outrun a fastener's grip, concealed-clip standing seam panel in a Kynar finish, 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 Portland 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 southern Maine means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

- ✓The report opens with your build year pulled from the City of Portland assessor's record, not guessed from the sidewalk by somebody looking at your clapboards
- ✓We are not lead inspectors and never pose as them; Maine law reserves identifying a hazard to a licensed inspector or risk assessor, and our reports say so in those words
- ✓Sound paint over sound wood gets left alone, and we will hand you a written estimate stating that the correct spend on your cornice this year is nothing
