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. Custer Roofing & Maintenance installs and repairs TPO, PVC, EPDM, and modified bitumen flat roofing systems throughout Custer.

Our Flat Roofing Process

1

Flat Roof Inspection

Before recommending repair, coating, or replacement, we inspect the entire flat roof system. Membrane condition, insulation integrity, and drainage patterns all factor into our recommendation.

2

Your Options

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

Flat roof installation requires specialized equipment and training. Our crew uses calibrated hot-air welders for TPO and PVC, torching equipment for modified bitumen, and proper adhesive systems for EPDM. Every seam, flashing, and penetration detail gets individual attention.

4

Warranty & Drainage Test

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 Custer Roofing & Maintenance for Flat Roofing?

13+ Years Flat Roof Experience

Custer Roofing & Maintenance has been installing and repairing flat roofs in Custer for 13 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.

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.

Manufacturer Warranties

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

Flat Roofing FAQ

A roof coating is a liquid-applied membrane, usually silicone or acrylic. That extends the life of an existing flat roof by 10-15 years. It works when the existing membrane and insulation are in reasonable shape. We core sample and moisture test to determine if your roof qualifies.

Ponding happens when the roof lacks adequate slope to drains or edges. Causes include compressed insulation, clogged drains, building settlement, or the original installation didn't include tapered insulation. We fix it with tapered ISO boards that create positive drainage.

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.

About Our Custer Flat Roofing Services

EPDM (rubber roofing) has a 50-year track record as a proven flat roofing membrane. Fully adhered EPDM over polyiso insulation is a reliable, cost-effective choice for Custer property owners who want proven performance without the premium price of TPO or PVC.

Every flat roof Custer Roofing & Maintenance installs includes proper drainage design. Tapered insulation, cricket saddles around rooftop equipment, and properly sized drains or scuppers ensure water moves off the roof, not into your building. Ponding water voids many manufacturer warranties. We eliminate it.
