Flat and Low-Slope Roofing in Draper, Utah

A flat or low-slope roof cannot rely on overlapping shingles to shed water quickly, which makes drainage paths and membrane details central to the installation.

Recurring standing water, open seams, membrane cracks or interior stains are reasons to inspect a low-slope roof, and we use the inspection to determine whether repair or replacement is appropriate.

A skylight interrupts the membrane and creates corners that must stay watertight, and the flashing has to stay continuous where horizontal roofing meets the raised curb.

Low-slope roofs have several transitions where the membrane turns up walls, curbs and equipment, and each opening has to be tied into the membrane system correctly.

Snowmelt can create drainage problems when water refreezes around a low-slope roof's outlets, and we pay attention to places where snowmelt repeatedly collects.

TPO, EPDM and modified bitumen are the primary low-slope roofing systems we evaluate; we compare the systems against the actual condition and use of the roof.

• TPO single-ply membrane: A TPO roof uses a thermoplastic single-ply membrane; the sheets are joined with heat-welded seams rather than overlapping shingle-style joints.
• EPDM rubber membrane: An EPDM roof uses a flexible synthetic rubber membrane; the joining method relies on EPDM-compatible tapes, adhesives and flashing products.
• Modified bitumen: A modified-bitumen roof uses reinforced asphalt-based membrane sheets; it can be useful on porches, garages and other modest low-slope areas.
• Existing membrane repairs: We evaluate existing flat-roof membranes for seam openings, punctures and flashing damage; we include drainage in the recommendation so the same problem is less likely to return.

We start a low-slope roofing project by understanding how water moves across the roof; we evaluate seams, edges and roof openings along with the drainage system.

• Assess drainage first: We trace the roof's drainage path and note areas where water tends to stand; the roof's drainage pattern guides the recommendation.
• Check the roof base and insulation: We check the materials below the membrane for moisture, damaged insulation and weak areas; this keeps the new roof from trapping an existing moisture problem.
• Install the membrane: We position and secure the membrane using the attachment method required for the system; the seam work follows the requirements of the selected roofing system.
• Build roof edges and transitions: Roof edges, parapets, walls and termination points receive dedicated membrane details; careful edge work helps keep the membrane secure at exposed perimeter locations.
• Detail drains and roof openings: Drains and roof openings receive membrane flashing designed for the selected roofing system; the selected roofing system determines the exact flashing materials and method.
• Test and inspect seams: We give the completed membrane seams and details a final inspection; we check for gaps or incomplete joints using the method suited to the 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 seams, drainage and membrane details must be completed as one water-control system.

1. Inspect the existing roofWe inspect the current membrane, drainage and perimeter details; we identify conditions that may affect the new roofing.
2. Confirm the roofing approachWe compare four options: repair, partial replacement, a new membrane over suitable existing roofing and full removal; we decide what can safely remain before new roofing is installed.
3. Correct problems below the membraneWe correct wet insulation, weak roof-base areas and other unsound materials first; the new roof should not depend on damaged material underneath.
4. Install the low-slope roofing systemWe install the selected low-slope membrane with its required attachment method; we complete the system-specific seam work before final inspection.
5. Check drainage and detailsThe final inspection covers drainage points, edges and membrane transitions; we check common leak points before sign-off.
