Flat and Low-Slope Roofing in West Haven, Utah

The lower the roof slope, the more the system depends on membrane seams and drainage details, which makes membrane seams, drainage, edges and roof openings especially important.

Repeated ponding, damaged seams and water staining are signs that a low-slope roof should be evaluated, so we can determine whether the problem starts with drainage, the membrane or both.

We look at drainage before assuming a membrane problem is causing ponding, and we note where water collects or has trouble reaching an exit point.

Snow on a low-slope roof eventually becomes a drainage problem as temperatures rise, and the roof needs a clear path for that meltwater to reach drains or scuppers.

Wind resistance depends on the membrane attachment and the way perimeter details are secured because a strong membrane can still fail if perimeter details are loose.

The right low-slope membrane may be TPO, EPDM or modified bitumen; drainage, roof details and the existing assembly guide the choice.

• TPO single-ply membrane: A TPO system relies on a thermoplastic membrane for its waterproof surface; heat-welded seams connect adjacent sheets into one continuous surface.
• EPDM rubber membrane: An EPDM system uses flexible rubber as its waterproof surface; installers join seams with compatible tapes or adhesives and use matching flashing products at details.
• Modified bitumen: A modified-bitumen system relies on reinforced asphalt-based sheets; it is often practical on garages, porches and smaller low-slope sections.
• Existing membrane repairs: We check the existing roof membrane for openings, surface damage and failed flashing; we inspect the drainage system for conditions that may be contributing to the damage.

Low-slope roofing work starts with the roof's drainage and existing condition; we also check the membrane, roof base, seams, edges and roof openings before deciding what needs work.

• Build roof edges and transitions: We finish the membrane where it meets roof edges, walls and parapets; proper termination helps prevent water or wind from getting behind the roofing.
• Detail drains and roof openings: We integrate drains and roof openings into the membrane system; the detail has to stay watertight where the flat roof is interrupted.
• Install the membrane: We install the main membrane surface using the layout requirements of the selected material; TPO seams are heat welded, while EPDM and modified-bitumen seams use compatible system-specific methods.
• Test and inspect seams: The final inspection includes the seams, edges and other membrane details; applicable systems may also allow seams to be probed or otherwise tested.
• Prepare the roof surface: Before membrane installation, we make sure the supporting roof surface is ready; we remove or prepare existing materials according to the condition of the roof.
• Check the roof base and insulation: The inspection includes the roof base and insulation before new roofing covers them; we correct conditions that would leave the new membrane over a failing base.

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.

Membrane roofing needs a different work sequence from a pitched shingle roof because the drainage path and continuous membrane have to work before the roof can keep water out.

1. Inspect the existing roofWe document the current roof before deciding on the work; we record damaged areas or locations that hold water.
2. Confirm the roofing approachThe next step is choosing the roofing approach that matches the existing conditions; we do not assume every low-slope roof needs full replacement.
3. Correct problems below the membraneWe make sure wet or damaged materials are addressed before the new roof is installed; the finished roof should sit over sound materials.
4. Install the low-slope roofing systemWe install the chosen flat-roof membrane over the prepared roof; we use compatible seam and flashing materials.
5. Check drainage and detailsWe inspect the completed water-control details across drains, edges, walls and roof openings; we check that runoff is directed away from vulnerable details.
