Signature Roofing did a first class job for me 26 years ago, and they did another first class job last month when they replaced my wood roof with a new composition shingle roof.
William Cotter was my Signature Roofing contact and he was responsive and comprehensive in his responses to my questions, providing a quote, advantages or optional roofing tiles to choose from and in coordinating their installation dates.
After a competitive bid process, I selected Signature Roofing to reroof my home with heavy wood shakes when I first bought the house 26 years ago. That original Signature roof had another 6 years of life left in it, but I had to replace it last month because my insurance company no longer insures wood roofs.
I highly recommend Signature Roofing. Not the cheapest, but certainly one of the best.

Had roof replaced by Signature in August. An opening in schedule allowed them to complete earlier than the scheduled slot od early October. William and roofing crew were on time , available for any questions, cleaned up and had new roof in 3 days. An issue with an area I felt was exposed was addressed and remedied the following day. Pricing was competitive, they are local and have been in business for a long time, as I had them replace my previous roof of 25 + years, which William advised I could have waited at least another year, which says alot about their business itself
