Flat and Low-Slope Roofing in Pleasant Grove, Utah

A shingle roof sheds water with slope and overlapping rows, while a low-slope roof works differently, so the membrane and drainage system have to work together across the entire roof.

A flat-roof inspection is useful when water keeps standing in low areas or the membrane develops visible damage before a small drainage or seam problem turns into a larger leak.

Roof curbs, equipment and wall connections interrupt the main membrane surface, and the corners and terminations need careful detailing.

Snowmelt can stay near seams, curbs and drains if the roof does not move it away, so drainage details matter throughout the freeze-and-thaw cycle.

A low-slope roof needs a clear route for rain and snowmelt to leave, so we can see whether slope, drains or low areas are slowing runoff.

A low-slope roof can use several membrane types, including TPO, EPDM and modified bitumen; we match the membrane to the roof layout, drainage and existing materials.

• TPO single-ply membrane: TPO roofing is built from a thermoplastic single-ply membrane; the seams are heat welded so neighboring sheets form a continuous waterproof layer.
• EPDM rubber membrane: EPDM roofing is built around a synthetic rubber membrane; the system uses compatible seam products and flashing materials at joints and roof openings.
• Modified bitumen: Modified-bitumen roofing uses reinforced sheets built from asphalt-based material; the system can be a good fit for smaller or more complex low-slope roof areas.
• Existing membrane repairs: We review the membrane, seams and flashing for isolated damage that may be repairable; we compare the damaged area with the overall roof before recommending repair or replacement.

A flat-roof project starts with an evaluation of drainage and the existing membrane; we use the membrane condition and roof-base condition to determine the scope.

• Check the roof base and insulation: Before covering the roof, we check for wet insulation, soft spots and damaged materials below the membrane; wet or damaged materials are addressed before the roof is closed up.
• Detail drains and roof openings: Drains, curbs, pipes, vents and rooftop equipment are flashed as part of the membrane system; we use the method required for the selected membrane at each transition.
• Install the membrane: We secure each membrane sheet using the method required for that roof; the membrane type determines whether adjoining sheets are welded, taped, adhered or otherwise joined.
• Assess drainage first: We inspect the roof for ponding areas and the routes water uses to drain; we check whether blockage, slope or settled materials are contributing to ponding.
• Prepare the roof surface: A reliable membrane roof starts with a clean and stable supporting surface; the condition of the existing roof determines how much removal or preparation is needed.
• Build roof edges and transitions: The perimeter of the roof receives its own edge and transition details; the edge work keeps the membrane secure where the roof changes direction.

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 membrane roof is installed in a different order from asphalt shingles since the roof depends on both drainage and an unbroken waterproof membrane.

1. Inspect the existing roofWe review the existing roofing, repair areas and drainage paths; the inspection establishes the roof's actual condition.
2. Confirm the roofing approachThe roofing approach depends on the condition of the existing membrane and materials below it; trapped moisture and drainage problems can change the recommendation.
3. Correct problems below the membraneWe deal with wet insulation and weak supporting materials before closing up the roof; this prevents the new membrane from hiding an existing problem.
4. Install the low-slope roofing systemWe install the new membrane after the roof base and drainage details are ready; we join the sheets according to the product requirements.
5. Check drainage and detailsOur final review includes drains, scuppers, curbs, walls and roof openings; we look for incomplete transitions that could undermine an otherwise sound membrane.
