Complete removal of failed flat or low-slope roofing membrane down to the deck, followed by installation of a new single-ply or built-up system with proper drainage slope, insulation, and membrane welding or bonding.
Why Choose Ironclad Roofing for Flat Roof Replacement
Why Choose Us
Ironclad Roofing brings commercial flat roof expertise to Kansas City projects of all sizes. We assess drainage patterns before selecting materials, because the number one cause of premature flat roof failure in the KC area is water that has nowhere to drain properly. We correct slope issues during replacement, not after.
Common Flat Roof Replacement Scenarios
Ponding Water and Membrane Blistering
Standing water on a flat roof accelerates UV degradation and eventually saturates insulation below the membrane, making repair increasingly ineffective over time.
EPDM Shrinkage and Seam Separation
Older EPDM rubber membranes on Kansas City commercial buildings shrink over decades, pulling away from flashings and splitting at field seams after heavy temperature cycling.
Roof Addition or Building Expansion
When a Kansas City business adds square footage or a residential addition requires a new flat section, a properly tied-in replacement system prevents leak-prone transitions.
Our Flat Roof Replacement Process
Drainage and Slope Assessment
Before any material is selected, we map existing drainage points, identify low spots, and determine whether tapered insulation or drain repositioning is needed.
Tear-Off and Deck Evaluation
Old membrane, insulation, and failed layers are removed. Wet or rotted decking is replaced before any new materials go down to prevent trapped moisture.
Insulation and Membrane Installation
Rigid insulation is fastened to code, then TPO, EPDM, or modified bitumen is installed and seamed using heat welding or adhesive bonding depending on the system chosen.
Flashing, Drains, and Final Inspection
All penetrations, curbs, parapet walls, and drains are flashed and sealed. We conduct a final water test before completing cleanup and handing over documentation.
Flat Roof Replacement - Frequently Asked Questions
If your membrane has widespread seam failures, multiple blistered or cracked sections, or if the insulation underneath has become saturated, repairs become a temporary patch over a failing system. An Ironclad inspection will show you exactly where the membrane stands and what the cost comparison looks like.
TPO is a white thermoplastic membrane that reflects UV heat - beneficial for Kansas City's hot summers - and is heat-welded at seams for a strong bond. EPDM is a black rubber membrane that has been used for decades and is durable but absorbs more heat. TPO has become the more common choice for new installations in the KC area.
A properly installed TPO or EPDM system on a Kansas City building should perform for 20 to 30 years with annual inspections and minor maintenance. Modified bitumen systems in the 15 to 25 year range. Longevity depends heavily on drainage quality and how quickly small issues are addressed.
Yes, and the transition flashing between the two systems is the most critical detail in that scenario. Ironclad Roofing handles combination roofs regularly on Kansas City homes with additions and garages, ensuring the flat-to-slope transition is waterproofed correctly with step and counter flashing.
