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

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

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.

Flat Roofing FAQ

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.

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.

About Our Lilliwaup Flat Roofing Services

TPO is our most-installed flat roof membrane. White reflective surface reduces cooling costs, hot-air welded seams create a watertight bond stronger than the membrane itself, and manufacturer warranties run 15-20 years. We install 60-mil and 80-mil TPO, fully adhered or mechanically attached over polyiso insulation.

Roof coatings can extend the life of an existing flat roof by 10-15 years for a fraction of replacement cost. Silicone coatings over TPO, EPDM, or metal work well when the existing membrane is still in decent condition. We core sample and moisture scan to make sure coating is the right call before recommending it.
