Flat and Low-Slope Roofing in Farmington, Utah

Flat roofs need a different roofing approach because runoff moves more slowly, so the membrane and drainage system have to work together across the entire roof.

A flat roof needs attention when water remains after normal drainage or the membrane starts showing damage before a small drainage or seam problem turns into a larger leak.

Roof-surface heat is part of the material choice on an exposed flat roof, so reflective materials may be useful when surface temperature is a concern.

Wind uplift can be strongest around the perimeter and corners of a flat roof, and the attachment method has to match the conditions the roof will face.

A flat roof still has to drain during freeze-and-thaw weather, and we evaluate low areas that may hold moisture after thawing.

Low-slope roofs can use TPO, EPDM or modified-bitumen membranes; we match the membrane to the roof layout, drainage and existing materials.

• TPO single-ply membrane: TPO roofing uses a thermoplastic membrane; the seams are heat welded so neighboring sheets form a continuous waterproof layer.
• EPDM rubber membrane: EPDM roofing uses a durable rubber membrane; the system uses compatible seam products and flashing materials at joints and roof openings.
• Modified bitumen: Modified-bitumen roofing combines asphalt with reinforcement for low-slope applications; the system can be a good fit for smaller or more complex low-slope roof areas.
• Existing membrane repairs: Existing membrane repairs begin with an inspection of seams, flashing and damaged surface areas; we compare the damaged area with the overall roof before recommending repair or replacement.

Drainage is the starting point for a low-slope roofing project; we use the membrane condition and roof-base condition to determine the scope.

• Build roof edges and transitions: We secure and finish the membrane at edges, parapets and wall transitions; the edge work keeps the membrane secure where the roof changes direction.
• Prepare the roof surface: We prepare a stable roof surface before installing the membrane; the condition of the existing roof determines how much removal or preparation is needed.
• Assess drainage first: We look at how runoff reaches drains, scuppers, gutters and roof edges; we check whether blockage, slope or settled materials are contributing to ponding.
• Install the membrane: We install the membrane using the layout and attachment method specified for that roof; the membrane type determines whether adjoining sheets are welded, taped, adhered or otherwise joined.
• Detail drains and roof openings: We build membrane flashing around drains, pipes, vents, skylight curbs, walls and equipment; we use the method required for the selected membrane at each transition.
• Check the roof base and insulation: We inspect the roof base and insulation before they are covered; wet or damaged materials are addressed before the roof is closed up.

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.

A flat-roof project has a different order of work than a shingle roof since the roof depends on both drainage and an unbroken waterproof membrane.

1. Inspect the existing roofWe review the existing roof surface, drainage and previous repairs; the inspection establishes the roof's actual condition.
2. Confirm the roofing approachThe existing roof condition determines whether we repair it, install new roofing over suitable existing materials or replace it; trapped moisture and drainage problems can change the recommendation.
3. Correct problems below the membraneWe remove or repair wet and damaged materials that should not remain below the new membrane; this prevents the new membrane from hiding an existing problem.
4. Install the low-slope roofing systemWe lay out and secure the chosen membrane system; we join the sheets according to the product requirements.
5. Check drainage and detailsWe check the completed roof at drains, scuppers, walls, curbs and roof openings; we look for incomplete transitions that could undermine an otherwise sound membrane.

Homeowners can call Courtland Roofing for flat-roof repair, replacement and membrane installation; we check for wet insulation or drainage problems before covering the existing roof.
