Flat and Low-Slope Roofing in South Weber, Utah

Low-slope roofing is designed around waterproofing and drainage rather than shingle overlap, which is why the roof base, membrane seams and drainage layout all matter.

Low-slope roofing should be checked when drains stop clearing water well, seams open or the membrane begins to blister, so we can identify whether the problem is isolated or spread across the roof.

We check drainage early because standing water can expose weak details, and we trace how water gets from the membrane to the roof's drainage points.

Water can linger around skylight curbs if the surrounding membrane and drainage are poorly detailed because slowly draining water may remain against the curb longer than on a steep roof.

Reflective membrane options can reduce surface heat on low-slope roofs, and a lighter reflective surface can reduce solar heat at the membrane.

We work with TPO, EPDM and modified bitumen rather than treating every flat roof as the same system; the existing roof and water-control details help determine which system fits best.

• TPO single-ply membrane: The waterproof layer in a TPO roof is a thermoplastic membrane; the seams are welded with heat so the separate sheets act as one membrane.
• EPDM rubber membrane: The waterproof layer in an EPDM roof is a flexible rubber membrane; the membrane is joined and flashed with materials compatible with EPDM.
• Modified bitumen: The waterproof layer in a modified-bitumen roof is a reinforced asphalt-based membrane; it is commonly considered for smaller flat sections and other low-slope areas.
• Existing membrane repairs: We look for open seams, punctures, flashing problems and other localized membrane damage; we evaluate both membrane damage and water movement before choosing the next step.

We plan low-slope roofing work from the drainage system outward; we use the drainage pattern and membrane condition to guide the project scope.

• Build roof edges and transitions: We complete roof edges and vertical transitions before considering the membrane system finished; the edge work completes the waterproofing at the roof perimeter.
• Test and inspect seams: The completed roof receives a seam and detail inspection; we correct incomplete seam details before considering the roof finished.
• Check the roof base and insulation: We evaluate the roof base and insulation for moisture or damage that should be corrected first; the roof should not be closed up over damaged or wet materials.
• Assess drainage first: We determine how water moves across the membrane and where it may collect; the inspection shows whether runoff is reaching its intended exit points.
• Install the membrane: We install the roofing membrane using the attachment method specified for the system; the selected material determines how adjoining sheets become a continuous waterproof surface.
• Prepare the roof surface: The surface below the membrane must be clean, stable and suitable for the system; we do not cover loose, wet or unsound materials with the new 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.

Low-slope roof work is planned differently from shingle replacement because the roof becomes watertight only after the membrane and drainage details are completed.

1. Inspect the existing roofWe inspect the membrane and note where water remains after storms; we use the findings to plan the next step.
2. Confirm the roofing approachWe decide whether suitable existing roofing can stay in place, can support a new membrane or needs to be removed; the recommendation reflects both the visible membrane and materials below it.
3. Correct problems below the membraneWe correct damaged materials beneath the membrane before new roofing goes over them; the corrected roof base gives the membrane a sound surface.
4. Install the low-slope roofing systemWe install the roofing system using the attachment method that fits the material; we install the membrane and seams as one roofing system.
5. Check drainage and detailsWe check the roof perimeter, drainage outlets and membrane transitions before sign-off; we verify that drains and transitions are complete.
