About Products: Flat Roof Membranes We Install
Your Flat & Low-Slope Roof Specialists
We install, repair, and maintain (through our turn-key maintenance program) a variety of membrane types:
- EPDM: Ethylene Propylene Diene Monomer (“Rubber roof” with glued seams)
- TPO: Thermoplastic Polyolefin (Mixture of Rubber and Thermoplastic, welded)
- PVC: Polyvinyl Chloride (Thermoplastic with heat welded seams)
Of course we have our preferences, for a variety of reasons. But we are experienced with all major roof membrane system types, and serve a wide range of flat roofing applications.
We’ve been a Dealer and Elite Roofing Contractor with Duro-Last Roofing, Inc. for 15 consecutive years.
This means when Grell Roofing installs a Duro-Last roof, in order for the manufacturer to warranty the system for up to 20 years, an independent crew of quality assurance professionals goes to every job site to check every linear foot of heat-welded seam and roof protrusion before signing off on the job.
Quality is assured on Duro-Last roofing system installs by experienced personnel employed by the manufacturer, not Grell Roofing. This verification system is how Duro-Last can confidently provide one of the longest and most comprehensive warranties in the roofing industry.
For Grell to qualify as an Elite Contractor, the QA teams rarely find a substandard weld, low fastener density or vent-to-roof-area ratio, nor other checklist issue. In other words, we do thorough work that allows you to rest assured as a building owner or maintainer. Of all the decisions you have to make to keep a facility running, hiring Grell Roofing won’t be one you regret.
Adding insulation and a reflective membrane to your roofing system pays for itself, especially compared to other flat and low-slope roof types. Grell Roofing will help you find rebates, credits, or programs to make a good financial decision even better.
References & Testimonials
We have used Grell Roofing on four different projects over the past three years in Storm Lake, Iowa. We have found them to be professional and have been pleased with the quality of their work. Their response time is great and they have always done what they told me they would do. I would recommend Grell Roofing based on my experience with them.
–Steve Brashears, Real Estate Specialists
A big thanks to Grell Roofing for a quick and professional installation of our new roof. They were incredibly respectful of our business as they worked. We barely even knew they were there. We are excited to finally be leak-free!
–Gena Becker, Anytime Fitness
We would like to take a moment to both thank and highly recommend Grell Roofing. We recently had our roof and gutters replaced by Grell Roofing. The materials and workmanship are top notch, and came with a 20 year transferrable warranty. The Grell representatives are very professional, courteous and accommodating. Every aspect of the project was explained in an understandable and detailed manner. The entire process took less than 2 days, and the finished project looks amazing. Again, we would highly recommend Grell Roofing to all our friends and associates. Thanks!
