All new roof systems are installed with the industries highest grade of materials. No flipping shingles up-side down or cutting 20yr shingles to make hip and ridge shingles for a 30yr roof. All necessary components are replaced on every roof. Each roof gets a complete overhaul to ensure the highest quality, weather tight roof for years to come. Every roof is installed with high quality waterproof & water-resistant underlayments, new ventilation, starter shingles (yielding the highest wind warranty available), and all roof penetrations are painted to match. We merge 2 of the best manufacturer warranties available by overlapping a Limited LIFETIME Shingle Warranty with a 20 YEAR, Non-Prorated, Extended Sure Start Warranty. Most roofing contractors that have the ability to offer an enhanced or extended manufacturer warranty will sell these warranties to the homeowner in order to increase profit. Here at Rock City Roofing, we pledge to donate a portion of the job proceeds (once paid in full) directly to the shingle manufacturer in order to register the new roof system with an enhanced warranty whenever applicable.
