Flat and Low-Slope Roofing in South Ogden, Utah

Low-slope roofing is designed around waterproofing and drainage rather than shingle overlap, which makes drainage paths and membrane details central to the installation.

Low-slope roofing should be checked when drains stop clearing water well, seams open or the membrane begins to blister, and we use the inspection to determine whether repair or replacement is appropriate.

Winter snow creates a long-duration water load once melting begins, and we look for low areas where meltwater may remain after the snow is gone.

A flat roof can hold moisture below the membrane as well as water above it, and we do not want new roofing to conceal an existing moisture problem.

We check drainage early because standing water can expose weak details, and we use the drainage path to identify low areas that may need attention.

We work with TPO, EPDM and modified bitumen rather than treating every flat roof as the same system; we compare the systems against the actual condition and use of the roof.

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

We plan low-slope roofing work from the drainage system outward; we evaluate seams, edges and roof openings along with the drainage system.

• Check the roof base and insulation: We evaluate the roof base and insulation for moisture or damage that should be corrected first; this keeps the new roof from trapping an existing moisture problem.
• Install the membrane: We install the roofing membrane using the attachment method specified for the system; the seam work follows the requirements of the selected roofing system.
• Build roof edges and transitions: We complete roof edges and vertical transitions before considering the membrane system finished; careful edge work helps keep the membrane secure at exposed perimeter locations.
• Test and inspect seams: The completed roof receives a seam and detail inspection; we check for gaps or incomplete joints using the method suited to the system.
• Assess drainage first: We determine how water moves across the membrane and where it may collect; the roof's drainage pattern guides the recommendation.
• Prepare the roof surface: The surface below the membrane must be clean, stable and suitable for the system; we prepare or remove existing layers as needed before the new membrane is installed.

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 roof work is planned differently from shingle replacement because seams, drainage and membrane details must be completed as one water-control system.

1. Inspect the existing roofWe inspect the membrane and note where water remains after storms; we identify conditions that may affect the new roofing.
2. Confirm the roofing approachWe decide whether suitable existing roofing can stay in place, can support a new membrane or needs to be removed; we decide what can safely remain before new roofing is installed.
3. Correct problems below the membraneWe correct damaged materials beneath the membrane before new roofing goes over them; the new roof should not depend on damaged material underneath.
4. Install the low-slope roofing systemWe install the roofing system using the attachment method that fits the material; we complete the system-specific seam work before final inspection.
5. Check drainage and detailsWe check the roof perimeter, drainage outlets and membrane transitions before sign-off; we check common leak points before sign-off.
