Why Do Flat Roofs Need a Different Approach in Draper?
A shingle roof uses slope and overlapping rows to move water downhill. A flat or low-slope roof in Draper relies on a waterproof membrane and carefully built seams instead. That makes drainage, penetrations, edges, and substrate condition especially important.

When Does a Flat or Low-Slope Roof in Draper Need Attention?
A low-slope roof does not have to be actively leaking before it needs service. In Draper, we look for ponding, loose seams, cracked sealant at details, surface damage, wet insulation, and drainage paths that no longer move water cleanly off the roof.
How Does Draper Weather Affect Flat and Low-Slope Roofing?
Skylights and roof curbs need special attention on a low-slope roof in Draper. Water moves more slowly around these raised openings, so the membrane flashing has to turn up the curb and stay watertight at corners and transitions.
Flat roofs in Draper often have more membrane flashing around walls, curbs, vents, and equipment. Those transitions need careful detailing because the field membrane can remain watertight while one poorly sealed penetration still allows water inside.
Winter drainage is important on Draper flat roofs. Snow can melt during warmer periods and refreeze near drains or edges. We pay attention to where water moves, where ice may restrict drainage, and whether low areas are likely to hold moisture for long periods.
What Flat Roofing Systems Do You Work With in Draper?
A Draper low-slope roof can use several membrane systems. TPO uses thermoplastic sheets with heat-welded seams. EPDM uses a rubber membrane with compatible seam and flashing details. Modified bitumen uses reinforced asphalt-based sheets. Each system handles details and repairs differently, so the existing roof and drainage layout matter when choosing between them.
- TPO single-ply membrane: TPO is a thermoplastic roofing membrane. Seams are joined with heat-welding equipment so separate sheets become part of one continuous roof surface.
- EPDM rubber membrane: EPDM is a flexible synthetic rubber membrane. Seams and roof details use compatible adhesives, tapes, or flashing products designed for the system.
- Modified bitumen: Modified bitumen is an asphalt-based low-slope membrane reinforced for roofing use. It can be practical on smaller flat sections, porches, garages, and similar areas.
- Existing membrane repairs: We can inspect existing flat-roof membranes for open seams, damaged flashing, punctures, failed details, and drainage problems before recommending repair or replacement.
What Does Flat and Low-Slope Roofing Work in Draper Include?
A low-slope roofing project in Draper starts with understanding how the roof handles water. We inspect drainage, membrane condition, substrate, seams, edges, and penetrations before deciding what work is appropriate.
- Assess drainage first: We identify where water currently flows, where it stands, and whether drains, scuppers, gutters, or roof edges are handling runoff correctly.
- Check the substrate and insulation: We look for soft areas, trapped moisture, damaged insulation, or substrate problems that should not be covered by a new membrane.
- Install the membrane: The membrane is laid out and attached according to the selected system. TPO seams are heat welded, while EPDM and modified-bitumen systems use their approved joining methods.
- Build roof edges and transitions: Edges, parapets, wall transitions, and termination points are finished so wind and water cannot work behind the membrane.
- Detail drains and penetrations: Drains, vents, pipes, skylight curbs, walls, and rooftop equipment receive membrane flashing designed for the selected roofing system.
- Test and inspect seams: We inspect completed seams and details before the roof is considered finished. On applicable systems, seams can be probed or otherwise checked for continuity.
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.

How Do You Approach a Flat Roof Job in Draper?
Flat roofing in Draper follows a different sequence from shingle work because drainage and membrane continuity have to be addressed before the roof is considered watertight.
- Find the drainage problem firstBefore changing the membrane, we determine whether the roof is holding water because of clogged drainage, poor slope, settled insulation, or another condition.
- Open up suspect areas when neededIf trapped moisture is suspected, the roof assembly may need targeted investigation before a new membrane is installed.
- Build a sound substrateWet or damaged materials are addressed as part of the approved scope so the new roof is not installed over a failing base.
- Install and join the membraneSeams are welded, taped, adhered, or otherwise completed according to the selected roofing system.
- Finish every transitionEdges, walls, curbs, drains, vents, and other interruptions are completed before the roof is signed off.

Draper homeowners choose Courtland Roofing for flat roofing because of how we approach the work:
- Drainage first: We look at where water sits and why before deciding whether the membrane itself is the main problem.
- Moisture checked before covering: We inspect for signs of wet insulation or damaged substrate so a new membrane does not simply hide an existing moisture problem.
- Membrane seams treated as critical details: TPO seams are heat welded, while EPDM and modified-bitumen systems use their approved seam methods. We use the correct detail for the system instead of treating every membrane the same.
- Flat work separated from shingle work: Low-slope roofs need membrane systems and details designed for slow drainage. We do not use shingles on roof sections that are too low-slope for them to perform properly.
- 5-year workmanship warranty: Our installation labor is backed by Courtland Roofing's 5-year workmanship warranty. Manufacturer material warranties depend on the selected roofing product and its terms.

Common Questions About Flat Roofing in Draper
What is modified bitumen roofing?
Modified bitumen is an asphalt-based roofing membrane reinforced for low-slope applications. It is often used on smaller flat sections and other roofs where an asphalt-based membrane is a practical fit.
Can wet insulation stay under a new flat roof?
Wet insulation should be identified before new roofing covers it. Trapped moisture can damage the roof assembly and reduce the value of the new membrane, so suspect areas need to be evaluated.
How do you know where a flat roof is leaking?
The interior stain is not always directly below the entry point. We inspect seams, drains, penetrations, flashing, ponding areas, and the roof assembly to trace the most likely path.
