About This Service
Flat Roof Installation, Repair & Replacement
Flat roofs are standard on commercial buildings, additions, and many modern homes — but they demand more careful waterproofing than pitched roofs. Without proper slope, drainage, and sealing, standing water leads to membrane stress, leaks, and accelerated deterioration.
We install and service all major flat roofing systems — TPO, EPDM, modified bitumen, and built-up roofing — selecting the right system for your building type, budget, and performance requirements. Every flat roof we install is properly sloped to drain, fully sealed at all penetrations, and inspected before handoff.
- Flat roof inspection & condition assessment
- TPO membrane installation
- EPDM rubber roofing installation
- Modified bitumen system installation
Residential Services
Everything Your Roof Needs
TPO Membrane Roofing
The most popular commercial flat roofing choice. Heat-welded seams, UV resistance, and energy-efficient white surface make it ideal for Oklahoma.
EPDM Rubber Roofing
Highly flexible rubber membrane that handles temperature extremes and freeze-thaw cycles exceptionally well. Long service life with low maintenance.
Modified Bitumen
Torch-applied bitumen systems that provide excellent waterproofing for low-slope residential additions, walkout decks, and smaller commercial roofs.
Flat Roof Repair
Re-seaming, blister repair, drain clearing, and membrane patching to extend the life of your existing flat roof system.
Drain & Drainage Solutions
Proper drainage is critical on flat roofs. We install, reposition, and clear drains and scuppers to eliminate standing water.
Roof Coating for Flat Roofs
Reflective elastomeric coatings applied over existing flat roof membranes to seal minor damage and reduce cooling costs.

Questions Answered
Common Questions
How long does a flat roof last?
TPO and EPDM systems typically last 20–30 years with proper maintenance. Modified bitumen runs 15–20 years. Built-up roofing can exceed 30 years. Lifespan depends heavily on installation quality and drainage.
What causes most flat roof failures?
Standing water is the leading cause. It adds structural load and accelerates membrane degradation. Poor seam work and neglected penetration sealing are also common failure points.
Which flat roofing system is best for my building?
It depends on your building size, existing structure, climate exposure, and budget. TPO is our most commonly recommended system for commercial properties. We’ll assess your building and give you a clear comparison.
How often should a flat roof be inspected?
Twice a year — spring and fall — plus after any significant storm. Flat roofs accumulate debris and standing water that cause slow damage if left unchecked.
