RV Roof Replacement — 45-Mil Commercial TPO & EPDM
When repair isn't enough, we install a new roof using the same membranes trusted on commercial buildings, hospitals, and schools across Minnesota — not the lightweight factory-grade material.
45-Mil TPO Replacement
White, reflective thermoplastic membrane — nearly double the thickness of standard RV roofs. Heat-welded seams create a single monolithic, leak-proof barrier. UV-resistant, energy-efficient, and reduces interior heat by up to 30%.
- 45-mil commercial thickness
- Heat-welded (not taped) seams
- Reflective white surface
- Resists UV, ozone, and weathering
Commercial EPDM Replacement
Black rubber roofing with a 50+ year commercial track record. Exceptional flexibility, weather resistance, and longevity — especially in Minnesota's cold extremes. Ideal for RVs that see heavy seasonal storage exposure.
- Industry-leading EPDM rubber
- Excellent cold-weather performance
- Reinforced flashing on every penetration
- Caulk-free, no annual maintenance
Our Replacement Process
On-Site Inspection
We document the existing roof condition with photos and provide a written quote.
Tear-Off & Decking Inspection
We remove the old membrane, inspect every inch of decking, and rebuild any soft or rotted areas before going further.
Structural Repair (If Needed)
Rotted rafters or decking get rebuilt with proper materials — often with R26 spray-foam insulation when applicable.
Membrane Installation
45-mil TPO heat-welded or EPDM bonded — with reinforced flashing at every vent, skylight, A/C unit, and seam.
Final Walk-Through
Photo documentation, warranty paperwork, and your new lifetime leak-free RV roof.
How Much Does RV Roof Replacement Cost in Minnesota?
RV roof replacement cost in Minnesota depends primarily on three factors: the size of your RV's roof, the membrane system chosen, and the structural condition of the existing roof deck.
Most sizes with standard EPDM or TPO and minimal deck work
Larger roof spans, slide-out transitions, potential decking work
Large roof areas, complex penetrations, structural repairs if needed
All replacement costs include tear-off, full deck inspection, membrane installation, and warranted penetration sealing. Written quote on-site before any work begins.
When Should You Replace Instead of Repair?
We always start with rv roof repair when it's viable — replacement is the more expensive option and we don't recommend it unless it's genuinely necessary. These are the situations where replacement is the right call:
- The membrane has failed or degraded across large sections — not just at individual penetrations
- Multiple soft spots indicate long-term water intrusion throughout the roof deck
- Prior repairs keep failing because the membrane itself is too far gone
- The decking and structural framing have widespread rot that can't be spot-patched
- You want a permanently maintenance-free roof for the next 20+ years
Not sure which way to go? A free on-site inspection is the honest answer — we'll tell you what we find and what makes the most sense financially and structurally.
Frequently Asked Questions
How much does it cost to replace an RV roof in Minnesota?
Complete RV roof replacement in Minnesota typically runs $4,000–$12,000 depending on the size of the RV, the membrane chosen (TPO or EPDM), and whether structural work (rotted decking or rafters) is needed underneath. Smaller travel trailers run toward the lower end; large Class A motorhomes run toward the higher end. We inspect first and provide a written quote.
TPO or EPDM — which is better for my RV?
Both are commercial-grade and vastly outperform factory RV membranes. TPO is white, highly reflective, and energy-efficient with heat-welded seams. EPDM is a black rubber that excels in extreme cold and has a 50+ year track record on commercial roofs. We'll recommend the right one based on your RV, climate exposure, and goals.
How long does a full RV roof replacement take?
Most full replacements take 2–3 days at your location. Larger fifth wheels or motorhomes, or jobs that require structural rebuild (rotted rafters, decking, etc.) can take 4–6 days. We'll give you a firm timeline before we start.
Do you replace the decking too if it's rotted?
Yes. We inspect all decking after tear-off. Any rotted or compromised sections are replaced with proper materials before the membrane goes down. We will not install a new roof over a bad deck.
Do I have to bring my RV to a shop?
No. We come to you anywhere in Minnesota. Most replacements happen at your home, storage lot, or campground. We bring everything needed for a complete installation.
What's the warranty on a full replacement?
Our installations carry an up to 20-year warranty on materials and workmanship plus a lifetime leak-free guarantee on covered systems. Our membranes also carry their own manufacturer warranty.
Can you replace the roof on any type of RV?
Yes — motorhomes (Class A, B & C), fifth wheels, travel trailers, toy haulers, campers, fish houses, and bus conversions. Each vehicle type has different roof shapes and attachment methods; we carry the right materials and techniques for all of them.
