Flat and Low-Slope Roofing in Santaquin, Utah

Low-slope roofing is designed around waterproofing and drainage rather than shingle overlap, so the membrane and drainage system have to work together across the entire roof.

Low-slope roofing should be checked when drains stop clearing water well, seams open or the membrane begins to blister before a small drainage or seam problem turns into a larger leak.

The membrane has to turn and seal around walls, vents, curbs and rooftop equipment, and the corners and terminations need careful detailing.

A flat roof can hold moisture below the membrane as well as water above it, and the roof plan should address those materials before they are covered.

Reflective membrane options can reduce surface heat on low-slope roofs, so reflective materials may be useful when surface temperature is a concern.

We work with TPO, EPDM and modified bitumen rather than treating every flat roof as the same system; we match the membrane to the roof layout, drainage and existing materials.

• TPO single-ply membrane: The waterproof layer in a TPO roof is a thermoplastic membrane; the seams are heat welded so neighboring sheets form a continuous waterproof layer.
• EPDM rubber membrane: The waterproof layer in an EPDM roof is a flexible rubber membrane; the system uses compatible seam products and flashing materials at joints and roof openings.
• Modified bitumen: The waterproof layer in a modified-bitumen roof is a reinforced asphalt-based membrane; the system can be a good fit for smaller or more complex low-slope roof areas.
• Existing membrane repairs: We look for open seams, punctures, flashing problems and other localized membrane damage; we compare the damaged area with the overall roof before recommending repair or replacement.

We plan low-slope roofing work from the drainage system outward; we use the membrane condition and roof-base condition to determine the scope.

• Check the roof base and insulation: We evaluate the roof base and insulation for moisture or damage that should be corrected first; wet or damaged materials are addressed before the roof is closed up.
• Detail drains and roof openings: We seal the membrane into drains and around roof openings using details made for the selected material; we use the method required for the selected membrane at each transition.
• Assess drainage first: We determine how water moves across the membrane and where it may collect; we check whether blockage, slope or settled materials are contributing to ponding.
• Install the membrane: We install the roofing membrane using the attachment method specified for the system; the membrane type determines whether adjoining sheets are welded, taped, adhered or otherwise joined.
• Build roof edges and transitions: We complete roof edges and vertical transitions before considering the membrane system finished; the edge work keeps the membrane secure where the roof changes direction.
• Test and inspect seams: The completed roof receives a seam and detail inspection; the exact seam check depends on the membrane and its installation method.

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 since the roof depends on both drainage and an unbroken waterproof membrane.

1. Inspect the existing roofWe inspect the membrane and note where water remains after storms; the inspection establishes the roof's actual condition.
2. Confirm the roofing approachWe decide whether suitable existing roofing can stay in place, can support a new membrane or needs to be removed; trapped moisture and drainage problems can change the recommendation.
3. Correct problems below the membraneWe correct damaged materials beneath the membrane before new roofing goes over them; this prevents the new membrane from hiding an existing problem.
4. Install the low-slope roofing systemWe install the roofing system using the attachment method that fits the material; we join the sheets according to the product requirements.
5. Check drainage and detailsWe check the roof perimeter, drainage outlets and membrane transitions before sign-off; we look for incomplete transitions that could undermine an otherwise sound membrane.
