Flat and Low-Slope Roofing in Harrisville, Utah

A low-slope roof depends more on waterproof membrane continuity than on gravity alone, so seams, drains, roof openings, edges and the roof base all become critical parts of the waterproof system.

You should have a low-slope roof checked when ponding, loose seams, bubbles, cracks or water staining appear because the inspection can separate a drainage problem from membrane failure.

A flat roof can remain watertight across the main membrane while leaking at one transition, so each transition has to remain watertight as water moves across the roof.

Low-slope roofing has to turn up and seal around skylight curbs, so the membrane has to turn up the curb and remain sealed at every corner.

Moisture beneath a flat roof can remain out of sight even when the surface looks intact, so we look for wet insulation and damage in the roof base before recommending new roofing.

We compare TPO, EPDM and modified bitumen for flat and low-slope roofs; we choose between them based on drainage, roof size, foot traffic, existing construction and budget.

• TPO single-ply membrane: The TPO system uses a thermoplastic roofing sheet; installers heat-weld the seams to join separate sheets into a continuous roof surface.
• EPDM rubber membrane: The EPDM system relies on a flexible rubber sheet; seams and roof details use compatible tapes, adhesives and flashing materials.
• Modified bitumen: The modified-bitumen system uses reinforced asphalt-based roofing sheets; it can work well on smaller flat sections, porches, garages and other compact roof areas.
• Existing membrane repairs: We check the current membrane for open joints, punctures and failed flashing; we also check drainage before deciding whether repair or replacement makes sense.

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

• Test and inspect seams: Our final review includes the membrane seams and detailed transitions; we use the inspection method appropriate for the selected membrane system.
• Assess drainage first: We map water movement across the roof and identify recurring low areas; we use that information to decide whether drainage changes belong in the roofing work.
• Detail drains and roof openings: We tie each drain or roof opening into the membrane with compatible flashing; the flashing directs water away from the opening.
• Install the membrane: We lay out the selected membrane and secure it as the system requires; we complete the seams using the joining method required for the membrane.
• Check the roof base and insulation: We look below the membrane surface for wet insulation and damaged roof-base materials; we address problem areas before the new membrane hides them.
• Build roof edges and transitions: We complete perimeter edges and wall transitions with secure membrane terminations; these details keep wind and water from working behind the 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.

We approach low-slope roofing differently from steep-slope shingle work because drainage and membrane continuity must be established before the roof is watertight.

1. Inspect the existing roofWe examine membrane condition, drainage and roof openings; we also note roof openings, repairs and areas that stay wet.
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; we base that decision on membrane condition, moisture and drainage.
3. Correct problems below the membraneWe address problem areas below the membrane before the new roof covers them; the new membrane should not be installed over a failing base.
4. Install the low-slope roofing systemWe install the new membrane according to the requirements of the selected material; we complete the seams with the method designed for that material.
5. Check drainage and detailsWe finish by reviewing the places where water leaves the roof or the membrane changes direction; we confirm that water has a clear path off the finished roof.
