Fields Roof Service is the BEST - from the first phone call to the last shingle! I got 3 bids. One was far below Fields, but I didn't feel confident that they would do the job correctly, and the other one was about the same as Fields. But I chose Fields because Jason was so knowledgeable. I felt that the job would be done right. He was organized and took care of every little detail. And the crew who worked on my roof were great, too. The roof looks great, and I love my 2 new skylights in my living room. I highly recommend Fields Roof Service!!!

Steve came out to help us investigate a potential leak. He was not only thorough in checking for the leak (which he verified was not coming from the roof) but was also extremely friendly and gave us suggestions on where the leak could be coming from as well as general roofing tips. This was my first time working with them, and will be highly recommending them to my friends and coworkers. Thanks Steve!"

Estimates provided upfront. Great work and new Sky Light installed as expected. They also offer if leaking again, call them any time.
