Flat roofs don't drain like sloped roofs. Water sits instead of running off. That fundamental difference means flat roofing requires specialized materials, installation methods, and drainage solutions. Lebanon Roofing & Maintenance installs and repairs TPO, PVC, EPDM, and modified bitumen flat roofing systems throughout Lebanon.

Our Flat Roofing Process

1

Flat Roof Inspection

We inspect the membrane surface, seam integrity, flashing condition, penetration seals, drain function, and overall drainage pattern. Core samples reveal whether the existing insulation is dry or waterlogged. Full findings provided in a written report.

2

Your Options

Your proposal includes membrane type, insulation R-value, drainage design, and warranty coverage. If multiple options make sense, we price all of them so you can compare and choose what fits your budget and goals.

3

Professional Installation

Our flat roof crew installs per manufacturer specifications and NRCA guidelines. TPO seams hot-air welded and probe-tested. Modified bitumen torch-applied in two plies. EPDM fully adhered with proper lap adhesive. Tapered insulation installed to create positive drainage.

4

Final Inspection

After installation, we verify drainage by checking water flow to all drain points. No ponding. Every seam tested. Manufacturer warranty registered, 15-20 year coverage depending on system and build-up.

Why Choose Lebanon Roofing & Maintenance for Flat Roofing?

Electronic Leak Detection

We use electronic testing to pinpoint flat roof leaks without destructive investigation. Find the source, fix the source, move on.

Core Sampling & Testing

Before recommending replacement or coating, we core sample the roof to check insulation moisture. Waterlogged insulation means tear-off. Dry insulation means options.

23+ Years Flat Roof Experience

Lebanon Roofing & Maintenance has been installing and repairing flat roofs in Lebanon for 23 years. Residential flat sections, commercial buildings, and everything in between.

Drainage Solutions

We solve ponding water with tapered insulation systems. Minimum quarter-inch per foot slope to drains or edges. Ponding is the number one flat roof killer. We eliminate it.

Flat Roofing FAQ

TPO is more energy-efficient (reflective white) and has stronger seam welds. EPDM is proven over 50+ years and typically costs less. Both are solid choices. We recommend TPO for energy savings and EPDM for budget-conscious projects.

Usually, yes. Most flat roof leaks originate at seams, flashings, or penetrations, all repairable. If the leak is from widespread membrane failure or waterlogged insulation, replacement is the better long-term solution.

Yes. Semi-annual inspections checking seams, flashings, drains, and membrane condition prevent small issues from becoming expensive repairs. Drain clearing is especially important. Clogged drains cause ponding that damages the membrane.
