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. Mcallister Roofing & Maintenance solves ponding with tapered insulation that creates positive drainage, minimum quarter-inch per foot slope to drains, scuppers, or roof edges.

PVC membrane is the only flat roofing material that resists animal fats and chemical exposure from rooftop grease exhaust. If you own a restaurant or commercial kitchen in Mcallister, PVC is the right choice. TPO and EPDM will deteriorate when exposed to kitchen grease venting.

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

Detailed Proposal

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

Expert Flat Roof Crew

Insulation board cut and installed with staggered joints. Membrane installed over insulation per manufacturer specs. All penetrations (pipes, vents, HVAC curbs) receive custom-fabricated flashing. Drains and scuppers cleared and properly connected to the new membrane system.

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 Mcallister.

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.

Electronic Leak Detection

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

Flat Roofing FAQ

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.

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.

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.
