Older house so had two layers of shingles removed and some extra work done for the new roof. Workers were cheerful and professional and got the job done in one day. They were careful to pick up nails and clean up. Roof and gutter look great!

What a fantastic company and group of people. They installed a roof on our church and did an amazing job. They worked their tails off to provide timely and exceptional service, even with a major hiccup in regard to OSB board (hiccup was not due to them). You will not be disappointed in their work ethic and service.

Integrity replaced the siding on my home. I was referred to this company by a friend. I'm glad I took their advice because I had a great experience! Everyone I worked with was knowledgeable, trustworthy, professional, and efficient. They did an excellent job keeping me informed through the entire process. The crew that came to my residence was hard working, precise, respectful and they finished early! Afterward, they cleaned up their workspace. My house looks beautiful! I recommend this company and will be contacting them again in the future for any additional work that I need done to my house.
