From my family to the Thunder Bay staff we want to send a sincere thank you. As new home owners we were met with a few minor issues and one major issue; being the need to replace our siding. I contacted Thunder Bay immediately and was greeted by the wonderful personality of Mr. Tom. Tom was detailed, educated in his content and built a rapport with my family that laid the foundation for our faith in the company. With such a major issue at hand, Thunder Bay took the lead and left us with little to no worries. They were quick, efficient and professional. This company made the project so seamless and was able to get it done within 3 days. We are currently very satisfied and you will be too!

I'm a project manager and have hired and worked with hundreds of contractors from a variety of trades over 25 years. I'm confident in my abilities to sort out the good ones from the not so good ones just because I've been doing it so long. I needed to replace my roof after storm damage deemed it necessary and urgent. I contacted four roofing contractors and received cost estimates from each one. This is where Thunder Bay stood out from the rest. Their estimate was not the cheapest of the four. It wasn't the highest either. Thunder Bay stood out due to their professionalism. Their project manager Tom provided a detailed explanation of how the Owens Corning roofing products Thunder Bay uses work together to create a roofing system that prolongs the functional life of your roof. The estimate itself was professionally prepared and detailed. Everything was spelled out clearly. Other contractors sent me a PDF of a hand written estimate that was hard to read and din't have much on details. Thunder Bay's professional approach convinced me they were the right contractor to replace my roof. After signing the contract, a date was scheduled and the TB crew were there on time and started work immediately. They were done in less than 8 hrs including clean up. Their workmanship was excellent and clean. I did, however, notice a couple of areas that needed additional attention and Thunder Bay Co-Owner Nick, scheduled a subsequent service visit and personally ensured everything was addressed and resolved to my satisfaction. Thunder Bays professionalism stood out from the other three contractors but TB's integrity and dedication to their customer was a welcome surprise. We chose the new Desert Rose shingles and we love our new roof. P.S. We also had Thunder Bay replace our gutters. And they're just perfect.

“Super Satisfied” After receiving several quotes for our roof replacement, we decided to go with Thunder Bay over the other companies. The choice was easy, because of their professionalism and the care given to our project. They treated us as valued customers addressing all our questions and concerns. Installation was fast and on schedule. The post inspection was prompt and informative. I wouldn’t hesitate to refer Thunder Bay to all my friends and family.

When I was ready to replace the roof and 3 skylights, I called 6 companies. When I contacted Thunder Bay, I immediately got a call back and set up an appointment. One of the owners came out to the house, used a drone and a satellite to measure the roof and look for damage. When I decided to go with Thunder Bay, employees brought out roofing materials about 3 business days later, and the roofers came out the next day, June 1. The roof and skylights were replaced that day, all old shingles and materials were removed, and the gentlemen used a magnet to clean up any stray nails. Today, 6/5, Steve came back out and examined the roof. He had already told me that he was going to take care of my roof just as if it were his mother's roof. There was just one tiny thing left to do, and it has been completed, as promised. We all worry about the companies that take money and never show up, but with Thunder Bay, I felt really safe. I got calls and emails regularly updating me on what was happening. The company did what they told me they would. I am very happy with the price, quality of materials, and workmanship.

These guys were great from the first call all the way through. I had recent storm damage & needed a quick turnaround. They did not disappoint, showed up when they said they would, provided a quick & fair estimate & returned to complete the repairs. They will have my business again if needed. Would highly recommend them to anyone looking for a dependable & honest company!
