Flat and Low-Slope Roofing in Goshen, Utah

Flat roofs need a different roofing approach because runoff moves more slowly, so water control depends on the membrane, seams, drains and transitions rather than shingles alone.

A flat roof needs attention when water remains after normal drainage or the membrane starts showing damage because the roof can deteriorate before water reaches the occupied space below.

Walls, roof curbs, vents and equipment create important flashing details on a flat roof, so flashing details are treated as part of the waterproof surface.

A flat roof still has to drain during freeze-and-thaw weather, so the drainage layout has to work through changing winter temperatures.

A membrane can hide wet insulation or damaged materials underneath, so the inspection includes signs of wet insulation or roof-base damage.

Low-slope roofs can use TPO, EPDM or modified-bitumen membranes; the membrane has to fit the roof rather than the other way around.

• TPO single-ply membrane: TPO roofing uses a thermoplastic membrane; heat-welded seams connect the sheets across the roof surface.
• EPDM rubber membrane: EPDM roofing uses a durable rubber membrane; seams and transitions are finished with products made for the rubber membrane.
• Modified bitumen: Modified-bitumen roofing combines asphalt with reinforcement for low-slope applications; the material often fits smaller roof sections and areas with several transitions.
• Existing membrane repairs: Existing membrane repairs begin with an inspection of seams, flashing and damaged surface areas; we determine whether the damage is localized enough for repair.

Drainage is the starting point for a low-slope roofing project; we inspect the materials below the membrane before planning the new work.

• Build roof edges and transitions: We secure and finish the membrane at edges, parapets and wall transitions; these details close paths where wind or water could get beneath the membrane.
• Check the roof base and insulation: We inspect the roof base and insulation before they are covered; we identify materials that should not remain under the finished roof.
• Test and inspect seams: We check each completed seam and critical detail before the roof is considered finished; the final seam review follows the requirements of the selected membrane.
• Assess drainage first: We look at how runoff reaches drains, scuppers, gutters and roof edges; we identify low areas before choosing the membrane work.
• Install the membrane: We install the membrane using the layout and attachment method specified for that roof; we join the membrane sheets with the method designed for that product.
• Detail drains and roof openings: We build membrane flashing around drains, pipes, vents, skylight curbs, walls and equipment; the goal is a continuous waterproof connection around every interruption.

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 a continuous membrane and working drainage system are essential to keeping water out.

1. Inspect the existing roofWe review the existing roof surface, drainage and previous repairs; we check for drainage or moisture concerns that need closer attention.
2. Confirm the roofing approachThe existing roof condition determines whether we repair it, install new roofing over suitable existing materials or replace it; we use the inspection to avoid removing repairable areas unnecessarily.
3. Correct problems below the membraneWe remove or repair wet and damaged materials that should not remain below the new membrane; we finish roof preparation before the waterproof surface covers problem areas.
4. Install the low-slope roofing systemWe lay out and secure the chosen membrane system; we use the joining method required for the selected membrane.
5. Check drainage and detailsWe check the completed roof at drains, scuppers, walls, curbs and roof openings; we confirm the roof handles water as planned.
