Flat and Low-Slope Roofing in Liberty, Utah

Water stays on a low-slope roof longer than it does on a steep roof, so the membrane and drainage system have to work together across the entire roof.

A low-slope roof may need service before it leaks if seams are opening or water repeatedly collects in the same areas before a small drainage or seam problem turns into a larger leak.

The condition below the membrane is part of the weather evaluation, and the roof plan should address those materials before they are covered.

Sun exposure affects both membrane temperature and long-term surface wear, so reflective materials may be useful when surface temperature is a concern.

Storm damage on a flat roof may show up as punctures, edge movement or blocked drainage, and both conditions matter even if the other part of the roof still looks normal.

The membrane choice usually comes down to TPO, EPDM or modified bitumen; we match the membrane to the roof layout, drainage and existing materials.

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

We begin by identifying where water moves and where it remains on the roof; we use the membrane condition and roof-base condition to determine the scope.

• Test and inspect seams: We inspect seams after installation to make sure the membrane is continuous at the joints; the exact seam check depends on the membrane and its installation method.
• Detail drains and roof openings: We detail the membrane around drains, vents, pipes, curbs, walls and rooftop equipment; we use the method required for the selected membrane at each transition.
• Prepare the roof surface: Membrane installation begins with a clean, stable surface; the condition of the existing roof determines how much removal or preparation is needed.
• Install the membrane: We place and secure the membrane according to the requirements of the chosen system; the membrane type determines whether adjoining sheets are welded, taped, adhered or otherwise joined.
• Assess drainage first: We evaluate where water leaves the roof and where drainage slows down; we check whether blockage, slope or settled materials are contributing to ponding.
• Check the roof base and insulation: We examine the roof base for weak areas and check the insulation for trapped moisture; wet or damaged materials are addressed before the roof is closed up.

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.

The work sequence on a low-slope roof differs from a shingle installation since the roof depends on both drainage and an unbroken waterproof membrane.

1. Inspect the existing roofWe inspect the current low-slope roof from membrane surface to drainage points; the inspection establishes the roof's actual condition.
2. Confirm the roofing approachWe use the inspection to decide how much of the existing roof can remain; trapped moisture and drainage problems can change the recommendation.
3. Correct problems below the membraneWe correct damaged roof-base materials and wet insulation before membrane installation; this prevents the new membrane from hiding an existing problem.
4. Install the low-slope roofing systemWe install the low-slope roofing material using the method designed for that system; we join the sheets according to the product requirements.
5. Check drainage and detailsWe check the completed roof at drainage points, edges, walls and openings; we look for incomplete transitions that could undermine an otherwise sound membrane.
