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 issues. 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.
