Flat and Low-Slope Roofing in Marriott-Slaterville, Utah

Water stays on a low-slope roof longer than it does on a steep roof, so water control depends on the membrane, seams, drains and transitions rather than shingles alone.

A low-slope roof may need service before it leaks if seams are opening or water repeatedly collects in the same areas because the roof can deteriorate before water reaches the occupied space below.

Storm damage on a flat roof may show up as punctures, edge movement or blocked drainage, so storm evaluation goes beyond looking for obvious tears in the membrane.

The condition below the membrane is part of the weather evaluation, so the inspection includes signs of wet insulation or roof-base damage.

Membrane flashing around walls, curbs and equipment deserves close attention, so flashing details are treated as part of the waterproof surface.

The membrane choice usually comes down to TPO, EPDM or modified bitumen; the membrane has to fit the roof rather than the other way around.

• TPO single-ply membrane: TPO is a single-ply thermoplastic roofing material; heat-welded seams connect the sheets across the roof surface.
• EPDM rubber membrane: EPDM is a single-ply synthetic rubber roofing material; seams and transitions are finished with products made for the rubber membrane.
• Modified bitumen: Modified bitumen is a reinforced asphalt membrane made for low-slope roofs; the material often fits smaller roof sections and areas with several transitions.
• Existing membrane repairs: We inspect the existing flat-roof system for damaged seams, flashing and membrane areas; we determine whether the damage is localized enough for repair.

We begin by identifying where water moves and where it remains on the roof; we inspect the materials below the membrane before planning the new work.

• Install the membrane: We place and secure the membrane according to the requirements of the chosen system; we join the membrane sheets with the method designed for that product.
• Assess drainage first: We evaluate where water leaves the roof and where drainage slows down; we identify low areas before choosing the membrane work.
• Prepare the roof surface: Membrane installation begins with a clean, stable surface; the roofing plan accounts for the condition of the existing roof and insulation.
• Check the roof base and insulation: We examine the roof base for weak areas and check the insulation for trapped moisture; we identify materials that should not remain under the finished roof.
• Build roof edges and transitions: Edges and raised transitions are finished as part of the waterproof roofing system; these details close paths where wind or water could get beneath the membrane.
• Test and inspect seams: We inspect seams after installation to make sure the membrane is continuous at the joints; the final seam review follows the requirements of the selected membrane.

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 a continuous membrane and working drainage system are essential to keeping water out.

1. Inspect the existing roofWe inspect the current low-slope roof from membrane surface to drainage points; we check for drainage or moisture concerns that need closer attention.
2. Confirm the roofing approachWe use the inspection to decide how much of the existing roof can remain; we use the inspection to avoid removing repairable areas unnecessarily.
3. Correct problems below the membraneWe correct damaged roof-base materials and wet insulation before membrane installation; we finish roof preparation before the waterproof surface covers problem areas.
4. Install the low-slope roofing systemWe install the low-slope roofing material using the method designed for that system; we use the joining method required for the selected membrane.
5. Check drainage and detailsWe check the completed roof at drainage points, edges, walls and openings; we confirm the roof handles water as planned.
