How to choose a roofing contractor 

All roofing contractors are not alike. Your roof is an important part of your home, both structurally and aesthetically, but you don't buy one everyday. Before you spend your money, spend time learning how to evaluate roofing contractors. Here are some guidelines to help you from the National Roofing Contractors Association (NRCA).

Are They Licensed and Insured?

Ensure the contractor is licensed, bonded and fully insured for liability and workers’ compensation to protect you from any liability arising from unforeseen accidents that might occur on your property.

Do They Have a Proven Track Record?

Check their completed projects. Get client references. Inquire about their project supervision and quality control procedures. Find out which roofing manufacturers have certified them as preferred installers. Choose a company committed to worker safety and education. 

Do They Offer a Quality Roof at a Fair Price?

Price is only one of the criteria for selecting a roofing contractor. Professionalism, experience and quality workmanship also should weigh heavily in your decision. Keep a healthy skepticism about the lowest bid. If it sounds too good to be true, it probably is. 

Don’t trust your home to just anyone.
Be a knowledgeable consumer and insist on working with a professional roofing contractor.
