Whether it's a residential flat section over a room addition, a garage with a flat top, or a full commercial building, New Underwood Roofing & Maintenance handles flat roofing in New Underwood with the same attention to detail. TPO for reflectivity, EPDM for budget, PVC for chemical resistance, modified bitumen for foot traffic.

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 New Underwood property owners who want proven performance without the premium price of TPO or PVC.

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

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

Completion & Warranty

Final roof inspection with drainage verification. Warranty paperwork provided. We recommend a maintenance plan to keep your flat roof performing and your warranty valid for its full term.

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.

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.

It depends on the application. TPO is great for energy efficiency. PVC resists grease and chemicals. EPDM is proven and affordable. Modified bitumen handles foot traffic well. We recommend based on your building's specific needs and budget.
