Before they start taking any measurements, ask to see the necessary credentials that prove the roofer is licensed, bonded and insured. This is very important because any reputable roofing contractor has these credentials. They are necessary to protect you from being responsible for any damage or injury to the contractor or to your home. Also make sure that the roofers that the contractor employs are experienced and have a long track record of quality workmanship. A good way to guarantee that the workers who install a roof on your home are good quality contractors is if the company has a policy of performing background checks on new hires. A good contractor will provide you with references for the company and for the roofers they employ.
Follow the contractor as he takes measurements and inspects the roof. Ask about the condition of the roof planking and trusses. Make sure that any underlying problems with the roofing frame or siding is inspected during this walk through in order for the roofing contractor to give you an accurate estimate. Rotting trusses will need to be replaced, so make sure your contractor is qualified to perform that type of work. It is important to know that re-shingling a roof will not stop roof trusses from rotting if they have already started. If there are any terms or procedures that you don’t understand, be sure to ask the contractor to fully explain them to you. This will ensure you know exactly what work needs to be done to your home and why the contractor will quote you a specific price.
After the roofing contractor explains the work that is needed, you can begin picking out the shingles and shingling materials. Be sure to ask about the warranty of the shingles and any maintenance that they may need. Copies of the warranties and instructions for care should be printed out and given to you, along with the manufacturer’s contact information.
Finally, talk about a timetable. Ask the contractor to give you a rough estimate at how long the job will take to complete. Also be sure to find out about clean up and debris removal.
The contractor will give you an estimate and if you agree to the terms and are satisfied with the price, you should take one final step. Check the references. If you are pleased with what the references have to say about the roofing contractor, you should hire them and rest easy knowing that your roofer will do quality work.
