A flat roof that ponds water is a flat roof with a problem. Standing water degrades membrane material, compresses insulation, and finds every weak point in the system. Leland Roofing & Maintenance solves ponding with tapered insulation that creates positive drainage, minimum quarter-inch per foot slope to drains, scuppers, or roof edges.

Our Flat Roofing Process

1

Free Evaluation

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

System Recommendation

Based on inspection findings, we recommend the right solution: targeted repair, a coating system, or full replacement. Each option is priced with material specs, warranty terms, and expected lifespan.

3

Membrane 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

Your flat roof gets a completion package: installation documentation, warranty certificates, drainage verification, and maintenance recommendations. We stand behind every flat roof we install in Leland.

Why Choose Leland Roofing & Maintenance for Flat Roofing?

Manufacturer Warranties

15-20 year manufacturer warranties on new flat roof installations. Coating systems warrantied for 10-15 years. All backed by certified installation.

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.

All Flat Roof Systems

TPO, EPDM, PVC, modified bitumen, built-up roofing, and coatings. We install the right system for your building, not whatever we have on the truck.

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.

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.

TPO and PVC: 15-25 years. EPDM: 20-30 years. Modified bitumen: 15-20 years. Lifespan depends on proper installation, drainage, and maintenance. Regular inspections catch small issues before they shorten roof life.

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.
