Flat and Low-Slope Roofing in Herriman, Utah

A low-slope roof depends more on waterproof membrane continuity than on gravity alone, so the membrane and drainage system have to work together across the entire roof.

You should have a low-slope roof checked when ponding, loose seams, bubbles, cracks or water staining appear before a small drainage or seam problem turns into a larger leak.

A flat roof can remain watertight across the main membrane while leaking at one transition, and the corners and terminations need careful detailing.

A storm can damage a low-slope roof even without tearing a large section of membrane, and both conditions matter even if the other part of the roof still looks normal.

The membrane is only one part of wind resistance on a low-slope roof, and the attachment method has to match the conditions the roof will face.

We compare TPO, EPDM and modified bitumen for flat and low-slope roofs; we match the membrane to the roof layout, drainage and existing materials.

• TPO single-ply membrane: The TPO system uses a thermoplastic roofing sheet; the seams are heat welded so neighboring sheets form a continuous waterproof layer.
• EPDM rubber membrane: The EPDM system relies on a flexible rubber sheet; the system uses compatible seam products and flashing materials at joints and roof openings.
• Modified bitumen: The modified-bitumen system uses reinforced asphalt-based roofing sheets; the system can be a good fit for smaller or more complex low-slope roof areas.
• Existing membrane repairs: We check the current membrane for open joints, punctures and failed flashing; we compare the damaged area with the overall roof before recommending repair or replacement.

Before planning low-slope roofing work, we first evaluate how the roof drains; we use the membrane condition and roof-base condition to determine the scope.

• Install the membrane: We lay out the selected membrane and secure it as the system requires; the membrane type determines whether adjoining sheets are welded, taped, adhered or otherwise joined.
• Check the roof base and insulation: We look below the membrane surface for wet insulation and damaged roof-base materials; wet or damaged materials are addressed before the roof is closed up.
• Prepare the roof surface: The roof surface has to be clean and sound before the new membrane goes down; the condition of the existing roof determines how much removal or preparation is needed.
• Detail drains and roof openings: We tie each drain or roof opening into the membrane with compatible flashing; we use the method required for the selected membrane at each transition.
• Assess drainage first: We map water movement across the roof and identify recurring low areas; we check whether blockage, slope or settled materials are contributing to ponding.
• Build roof edges and transitions: We complete perimeter edges and wall transitions with secure membrane terminations; 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.

We approach low-slope roofing differently from steep-slope shingle work since the roof depends on both drainage and an unbroken waterproof membrane.

1. Inspect the existing roofWe examine membrane condition, drainage and roof openings; the inspection establishes the roof's actual condition.
2. Confirm the roofing approachAfter the inspection, we decide whether to repair the roof, install a new membrane over suitable existing roofing or replace it; trapped moisture and drainage problems can change the recommendation.
3. Correct problems below the membraneWe address problem areas below the membrane before the new roof covers them; this prevents the new membrane from hiding an existing problem.
4. Install the low-slope roofing systemWe install the new membrane according to the requirements of the selected material; we join the sheets according to the product requirements.
5. Check drainage and detailsWe finish by reviewing the places where water leaves the roof or the membrane changes direction; we look for incomplete transitions that could undermine an otherwise sound membrane.
