From the initial project meeting with us to the final installation by the crew this was as smooth and professional experience I have had with a Home Contractor in a long time. The owner Tom, not a salesperson, made the initial site visit and went through the options and installation process in a very thorough way. He not only answered any question I had but provided and explained samples of the all the products used in replacing the roof. I am one of those people who does their homework before reaching out for bids. I knew what roofing product I wanted and how it needed to be installed to insure it would live up to its rated weather resistance and longevity. So my questions were specific and I knew what the answers should be and Tom did not disappoint. The quote I received was in the middle of the pack price wise, but at the top of the list for thoroughness and clearly outlining what I was getting and any contingency costs for things like replacing rotted roof plywood sheets. My roof was 30 years old so I expected we would have to replace a number of sheets and I could easily calculate the costs based on the details of the contract. Weather can play havoc with scheduling a roof replacement but Diana in the front office was a gem about promptly notifying me when any change was needed. and working with to identify the next soonest date that was convenient. In spite of a lot of wet weather during the period around my installation the date was only moved a few days. The installation crew was prompt, professional and the crew lead was very gracious in answering questions I had during the process and allowing me to inspect the old plywood sheets that had to be replaced. The team was very fastidious in making every effort to sweep the property for debris and nails, and cleaned up the few places where some of the old roofing material left dirt behind as it fell from the roof. The final result is wonderful and the process was efficient and painless. I now have added peace of mind that my roof is up to the increasingly high winds we now experience during Spring and Summer storms. I can’t recommend Certified highly enough for roof and skylight replacement, especially if you want the best install possible for Certified Roofing products.
