Flat & Low Slope Roofing Fort Myers & Naples

Flat and Low Slope Roofing for Southwest Florida

Flat and low slope roofing requires technical skill, and it is one of our specialties. Our technicians are trained in TPO, modified bitumen, tapered ISO insulation and roof coatings, and we install and repair low slope roofs on homes and businesses across Fort Myers, Naples, Bonita Springs, Estero and Cape Coral.

Water does not run off a flat roof the way it runs off a pitched one. It sits, so every seam, drain and wall flashing has to be right. International Roofing is a family-owned, licensed and insured Florida Certified Roofing Contractor (license CCC1332289), and every roof we install comes with our 10-year workmanship warranty and the manufacturer's warranty.

The systems we install

TPO single-ply membrane

A white, reflective membrane that is fully adhered to the roof and heat-welded at every seam into one continuous, watertight surface. It is the system for modern flat-roof homes and for commercial buildings. On a recent modern new-construction home in Naples we installed a .060 TPO system over tapered insulation, fully adhered with heat-welded seams and finished with custom white coping.

Modified bitumen

Asphalt-based rolled roofing reinforced with a polyester or fiberglass mat, installed in layers with a granulated cap sheet. A durable choice for lanai roofs, additions and older flat roofs.

Tapered ISO insulation

Polyiso insulation cut in wedges to build slope into a roof that has none, so water moves to the drains instead of ponding. Ponding water is the most common cause of flat roof failure, and tapered insulation is how we prevent it.

Roof coatings

A coating applied over a sound existing roof can extend its life and reflect heat at a fraction of the cost of replacement. We will tell you honestly when a coating is the right call and when the roof underneath needs to be replaced.

What Southwest Florida does to a flat roof

Ponding. Summer downpours drop inches of rain in an hour. Any low spot holds water, and standing water is what finds a seam.
Sun. Ultraviolet exposure dries out asphalt and ages membranes. Reflective TPO and coatings resist it.
Wind. Hurricane uplift peels membranes back from the edges. Edge metal, coping and the attachment pattern matter as much as the membrane.
Drains and scuppers. Leaves and debris block them, water backs up, and the leak shows up inside. Regular cleaning through our SHIELD Maintenance Program prevents most of it.

Repair, coat or replace?

Our inspection tells you which one you need, with photos and a written report. A split seam or a failed pipe boot is a repair. A roof that is sound but aging may be a candidate for a coating. A roof with saturated insulation, widespread blistering or ponding that never dries needs replacement, ideally with tapered insulation so the problem does not come back. Repairs are available 24 hours a day through our Emergency Roof Repairs service.

Low slope roofing questions

Can you put a flat roof on a lanai or addition next to a tile or shingle roof?
Yes. The tie-in flashing between the two roofs is where the care matters most, and it is one of the most common jobs we do.

Is a white TPO roof worth it?
On a flat roof that faces the sun all day, a reflective surface keeps the deck and the rooms below it cooler and slows the aging of the roof.

Do you work on commercial buildings?
Yes. We repair and replace roofs on homes and businesses throughout Lee and Collier County.
