Flat and Low-Slope Roofing in Centerville, Utah

A flat or low-slope roof cannot rely on overlapping shingles to shed water quickly, so seams, drains, roof openings, edges and the roof base all become critical parts of the waterproof system.

Recurring standing water, open seams, membrane cracks or interior stains are reasons to inspect a low-slope roof because the inspection can separate a drainage problem from membrane failure.

We start the weather review by looking at how the roof drains; we check whether water reaches drains or scuppers instead of remaining in low areas.

Severe weather can affect both the membrane surface and the drainage system, so we inspect both the roofing surface and the way water is leaving the roof.

Several layers on an older flat roof can make the condition below the surface harder to see. We evaluate the existing assembly before deciding whether to repair the roof, install a new membrane over suitable existing roofing or remove the old roofing.

TPO, EPDM and modified bitumen are the primary low-slope roofing systems we evaluate; we choose between them based on drainage, roof size, foot traffic, existing construction and budget.

• TPO single-ply membrane: A TPO roof uses a thermoplastic single-ply membrane; installers heat-weld the seams to join separate sheets into a continuous roof surface.
• EPDM rubber membrane: An EPDM roof uses a flexible synthetic rubber membrane; seams and roof details use compatible tapes, adhesives and flashing materials.
• Modified bitumen: A modified-bitumen roof uses reinforced asphalt-based membrane sheets; it can work well on smaller flat sections, porches, garages and other compact roof areas.
• Existing membrane repairs: We evaluate existing flat-roof membranes for seam openings, punctures and flashing damage; we also check drainage before deciding whether repair or replacement makes sense.

We start a low-slope roofing project by understanding how water moves across the roof; we then inspect the membrane, roof base, seams, edges and roof openings.

• Assess drainage first: We trace the roof's drainage path and note areas where water tends to stand; we use that information to decide whether drainage changes belong in the roofing work.
• Detail drains and roof openings: Drains and roof openings receive membrane flashing designed for the selected roofing system; the flashing directs water away from the opening.
• Check the roof base and insulation: We check the materials below the membrane for moisture, damaged insulation and weak areas; we address problem areas before the new membrane hides them.
• Prepare the roof surface: A new membrane needs a sound, clean surface underneath it; the existing assembly determines whether the project needs tear-off, installing new roofing over suitable existing materials or insulation replacement.
• Install the membrane: We position and secure the membrane using the attachment method required for the system; we complete the seams using the joining method required for the membrane.
• Test and inspect seams: We give the completed membrane seams and details a final inspection; we use the inspection method appropriate for the selected membrane system.

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.

Low-slope roofing follows a different installation sequence from shingles because drainage and membrane continuity must be established before the roof is watertight.

1. Inspect the existing roofWe inspect the current membrane, drainage and perimeter details; we also note roof openings, repairs and areas that stay wet.
2. Confirm the roofing approachWe compare four options: repair, partial replacement, a new membrane over suitable existing roofing and full removal; we base that decision on membrane condition, moisture and drainage.
3. Correct problems below the membraneWe correct wet insulation, weak roof-base areas and other unsound materials first; the new membrane should not be installed over a failing base.
4. Install the low-slope roofing systemWe install the selected low-slope membrane with its required attachment method; we complete the seams with the method designed for that material.
5. Check drainage and detailsThe final inspection covers drainage points, edges and membrane transitions; we confirm that water has a clear path off the finished roof.
