Flat and Low-Slope Roofing in Highland, Utah

A low-slope roof depends more on waterproof membrane continuity than on gravity alone, which means drains, flashing, seams and roof openings need careful detailing.

You should have a low-slope roof checked when ponding, loose seams, bubbles, cracks or water staining appear because standing water can keep pressure on weak seams and roof openings.

We pay close attention to drainage because low-slope roofs can hold water in shallow areas, and compare ponding areas with the location of drains, scuppers and roof edges.

A flat roof can remain watertight across the main membrane while leaking at one transition, so we inspect those transitions separately from the open main membrane surface.

A storm can damage a low-slope roof even without tearing a large section of membrane, so the post-storm inspection includes drainage as well as visible membrane damage.

We compare TPO, EPDM and modified bitumen for flat and low-slope roofs; each system uses different seam and flashing methods.

• TPO single-ply membrane: The TPO system uses a thermoplastic roofing sheet; installers use heat-welding equipment to join the sheets at their seams.
• EPDM rubber membrane: The EPDM system relies on a flexible rubber sheet; seams are completed with materials designed specifically for the EPDM system.
• Modified bitumen: The modified-bitumen system uses reinforced asphalt-based roofing sheets; it can suit compact roof sections where an asphalt-based membrane is appropriate.
• Existing membrane repairs: We check the current membrane for open joints, punctures and failed flashing; we check whether an isolated repair will address the underlying cause.

Before planning low-slope roofing work, we first evaluate how the roof drains; we inspect the membrane, underlying roof base, seams, perimeter edges and roof openings as one system.

• Build roof edges and transitions: We complete perimeter edges and wall transitions with secure membrane terminations; these exposed locations need dependable attachment and water-control details.
• Check the roof base and insulation: We look below the membrane surface for wet insulation and damaged roof-base materials; we want the new membrane installed over sound, dry materials.
• Assess drainage first: We map water movement across the roof and identify recurring low areas; the results help determine whether the roof needs membrane work, drainage work or both.
• Prepare the roof surface: The roof surface has to be clean and sound before the new membrane goes down; we decide whether existing layers can remain only after evaluating the roof base and insulation.
• Install the membrane: We lay out the selected membrane and secure it as the system requires; we use the seam technique specified for TPO, EPDM or modified bitumen.
• Detail drains and roof openings: We tie each drain or roof opening into the membrane with compatible flashing; the flashing keeps water moving toward drainage instead of into the roof.

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.

We approach low-slope roofing differently from steep-slope shingle work because water control depends on drainage, seams and membrane continuity rather than overlapping shingles.

1. Inspect the existing roofWe examine membrane condition, drainage and roof openings; we use the inspection to decide whether repair or replacement is appropriate.
2. Confirm the roofing approachAfter the inspection, we decide whether to repair the roof, install a new membrane over suitable existing roofing or replace it; the scope should match the actual extent of the problem.
3. Correct problems below the membraneWe address problem areas below the membrane before the new roof covers them; the goal is a stable, dry base for the new roofing system.
4. Install the low-slope roofing systemWe install the new membrane according to the requirements of the selected material; the attachment and seam details follow the selected system.
5. Check drainage and detailsWe finish by reviewing the places where water leaves the roof or the membrane changes direction; we verify that drainage and waterproofing work together.
