Flat and Low-Slope Roofing in Granite, Utah

Flat roofs need a different roofing approach because runoff moves more slowly, which is why the roof base, membrane seams and drainage layout all matter.

A flat roof needs attention when water remains after normal drainage or the membrane starts showing damage, so we can identify whether the problem is isolated or spread across the roof.

Water movement is a primary concern on a low-slope roof, and we trace how water gets from the membrane to the roof's drainage points.

An older membrane roof may have repairs or wet materials hidden below later layers because wet materials should not simply remain beneath another membrane.

Wind and debris can puncture membranes, lift edges or clog roof drains because perimeter damage and clogged drainage can be just as important as surface punctures.

Low-slope roofs can use TPO, EPDM or modified-bitumen membranes; the existing roof and water-control details help determine which system fits best.

• TPO single-ply membrane: TPO roofing uses a thermoplastic membrane; the seams are welded with heat so the separate sheets act as one membrane.
• EPDM rubber membrane: EPDM roofing uses a durable rubber membrane; the membrane is joined and flashed with materials compatible with EPDM.
• Modified bitumen: Modified-bitumen roofing combines asphalt with reinforcement for low-slope applications; it is commonly considered for smaller flat sections and other low-slope areas.
• Existing membrane repairs: Existing membrane repairs begin with an inspection of seams, flashing and damaged surface areas; we evaluate both membrane damage and water movement before choosing the next step.

Drainage is the starting point for a low-slope roofing project; we use the drainage pattern and membrane condition to guide the project scope.

• Prepare the roof surface: We prepare a stable roof surface before installing the membrane; we do not cover loose, wet or unsound materials with the new membrane.
• Assess drainage first: We look at how runoff reaches drains, scuppers, gutters and roof edges; the inspection shows whether runoff is reaching its intended exit points.
• Test and inspect seams: We check each completed seam and critical detail before the roof is considered finished; we correct incomplete seam details before considering the roof finished.
• Build roof edges and transitions: We secure and finish the membrane at edges, parapets and wall transitions; the edge work completes the waterproofing at the roof perimeter.
• Detail drains and roof openings: We build membrane flashing around drains, pipes, vents, skylight curbs, walls and equipment; these details keep roof openings from becoming weak points.
• Check the roof base and insulation: We inspect the roof base and insulation before they are covered; the roof should not be closed up over damaged or wet materials.

Which of those apply depends on what the inspection finds. We would rather tell you the roof needs a repair than sell you a replacement it does not need yet.

A flat-roof project has a different order of work than a shingle roof because the roof becomes watertight only after the membrane and drainage details are completed.

1. Inspect the existing roofWe review the existing roof surface, drainage and previous repairs; we use the findings to plan the next step.
2. Confirm the roofing approachThe existing roof condition determines whether we repair it, install new roofing over suitable existing materials or replace it; the recommendation reflects both the visible membrane and materials below it.
3. Correct problems below the membraneWe remove or repair wet and damaged materials that should not remain below the new membrane; the corrected roof base gives the membrane a sound surface.
4. Install the low-slope roofing systemWe lay out and secure the chosen membrane system; we install the membrane and seams as one roofing system.
5. Check drainage and detailsWe check the completed roof at drains, scuppers, walls, curbs and roof openings; we verify that drains and transitions are complete.
