After extensive research of local roofing companies and materials, and estimates from 5 companies ranging in cost from $5065 to almost $8000, I chose Cambridge Roofing for quality of product, factory certification for installation of GAF products, what they proposed to do, the recommendations from satisfied customers, evidence of good service, and the overall cost of $5875 which was very competitive for a steep pitched roof. They also agreed to fix my leaking roof earlier than other companies and tarped the problem area until they could do a complete roofing job. The roofers were knowledgeable, worked really hard, did an excellent job, and cleaned up meticulously to avoid problems for my neighbours' cars. The roof looks really great and I no longer worry when heavy rain or storms are forecast. I would happily recommend this company to family and friends.
