Jason started out with sharing the roofing procedure from start to finish in our home. As he left we felt very comfortable choosing guaranteed roofing to replace our existing one. Thanks to Jason and his team they finished our new roof within a day and a half just in time for winter. We could not be happier with our new roof as well as the cost! Thanks to Jason and his team we now have a roof we love for years to come!

I had Guaranteed Roofing install my roof in early December. From the original meeting & proposal to the installation and final invoice, Jason & team were professional throughout. What Jason quoted and promised, he delivered. Jason was on sight during the install and the team did a great job cleaning up when the project was finished. I would highly recommend this team to install your roof. They provide a hometown feel with world class service. Great job and thank you.

We called Jason & he was able to take care of our needs in a timely manner. His company will be called whenever we need his expertise. By the way, after the severe rain the other day our fireplace ws nice and dry!

Removal of existing shingle roof, replace with 30 yr architectural shingles, replace 3 skylights with velux updated models, install new sun tube to add natural light to lower level, replace two power vents with new solar power roof vents. Remove bad sheathing due to leaky condition, replace with new wood. Jason provided excellent communication from start to finish. He was knowledgeable, prompt, and very pleasant to work with. The job was finished in one day, testimony to the skills of his crew. I watched the whole process and have 100% confidence in the quality of my roof & skylight installation. At the end of the day they thoroughly cleaned up the area. Overall – exceeded expectations. Would not hesitate to recommend.
