Flat and Low-Slope Roofing in Taylorsville, Utah

A flat roof needs continuous waterproofing because water does not leave the surface as quickly, so standing water and weak transitions deserve more attention than they do on a steep roof.

A flat roof deserves attention when drainage slows, seams move or signs of moisture show up inside, so the cause can be identified before more roofing or insulation is affected.

A flat roof may see repeated cycles of snow accumulation, melting and refreezing, so we evaluate where the water will go as snow turns to runoff.

The roof's ability to move water is one of the first conditions we review because repeated standing water can keep pressure on seams and flashing.

Older low-slope assemblies need careful evaluation before another layer is added because installing another roofing layer over the existing materials may not make sense if moisture is trapped below.

TPO, EPDM and modified bitumen provide different ways to waterproof a low-slope roof; roof shape, drainage, exposure and repair needs affect the decision.

• TPO single-ply membrane: TPO uses a thermoplastic sheet as the main roof membrane; heat welding joins the individual sheets into a continuous membrane.
• EPDM rubber membrane: EPDM uses a synthetic rubber sheet as the main roof membrane; compatible adhesives, tapes and flashing products are used to complete seams and details.
• Modified bitumen: Modified bitumen uses reinforced asphalt sheets as the main roof membrane; smaller flat roofs and detailed roof sections are common places to consider it.
• Existing membrane repairs: We inspect existing low-slope roofing for failed seams, punctures and damaged flashing; we use the overall membrane condition to decide whether a repair is worthwhile.

Before choosing the work, we evaluate how the roof currently manages water; we check the roof base and membrane details before deciding whether repair or replacement is appropriate.

• Assess drainage first: The drainage review follows runoff from the roof surface to its exit points; we use the drainage review to plan the repair or replacement around actual water movement.
• Build roof edges and transitions: Perimeter edges, parapets and wall transitions are tied into the membrane system; the finished transitions protect vulnerable perimeter areas from wind and water.
• Check the roof base and insulation: We look for trapped moisture and damaged materials in the roof base and insulation; we correct damaged areas before membrane installation.
• Prepare the roof surface: We prepare the roof base so the membrane is not installed over loose or unsound material; the project may require removing old roofing, replacing insulation or preparing suitable existing materials to remain under the new membrane.
• Detail drains and roof openings: Membrane flashing is installed at drains, walls, curbs and other roof openings; these areas receive the same attention as the main membrane seams.
• Install the membrane: We secure the membrane with the attachment method that matches the chosen roof system; we complete each seam with materials and methods compatible with the selected 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.

The installation order changes when the roof uses a membrane instead of shingles since the membrane and drainage details together make the roof watertight.

1. Inspect the existing roofWe examine the roof surface, edges, openings and drainage; we include previous repairs and recurring ponding areas in the evaluation.
2. Confirm the roofing approachWe compare the available repair and replacement approaches; the existing assembly guides how much removal is necessary.
3. Correct problems below the membraneWe repair or remove unsound materials that could compromise the new membrane; we do not want trapped moisture sealed into the roof assembly.
4. Install the low-slope roofing systemWe complete the main membrane surface with the selected low-slope system; the main membrane surface and its joints become one waterproof surface.
5. Check drainage and detailsThe last review focuses on drainage and the detailed areas around edges and openings; we complete this review before considering the membrane system finished.
