"Contracted Federal Building and Roofing with Richard and his team after Listening to Richard's suggestions during the estimate. Had bad water damage to many Rafter Tails as well as a severe leak in the garage, Had several Contractors out for estimates some wanting to go a much more expensive route to repair the damaged wood on the Rafters as well as suggesting a complete Torch down on the entire roof which was not needed, which came with a less than desirable Warranty along with higher costs. Richard gave me peace of mind with his knowledge and suggestions which in turn provided a much longer Warranty and cheaper more effective route to repairing the damaged Rafter tails,all at a very reasonable price compared to other estimates. Any Contractor should have been able to provide me with these suggestions and alternatives but failed to do so. Richard and his team were Professional, polite,cleaned up thoroughly each and every day and completed the job on time as scheduled."

"I highly recommend Robert Noy, from start to finish he was honest straightforward, and very professional. He gave me a great price and unlike many other contractors never tried to upsell me on work or services I didn’t need. He communicated well throughout the entire process and the job was completed quickly and efficiently. I wouldn’t call anyone else for my future roofing needs."

"Corey was able to come and resolve our issue in a timely manner. Best way to communicate is through a phone call. Leave a message if it's not answered and they will get back to you as soon as they can. Had a leak in my roof that kept springing up. He had someone come look at it the same day, and they're able to patch it up just before the rain. I'm grateful for the quick resolution."
