When it comes to the safety of your family, home and property, you want to make sure that any work performed on your roof is done by a professional. Not all roofing contractors are created equal, however. While regulations for roofing are somewhat looser than other trades such as plumbing, HVAC and electrical, it is still important to choose a licensed and certified roofer to ensure that your repairs or installation is done properly, safely and in compliance with local building codes and any homeowners association guidelines that may apply.

In the US, the National Roofing Certification certified roofers and Inspection Association (NRCIA) oversees roofing certification. In order to become a NRCIA certified roofer, a contractor must meet a number of requirements including being fully licensed and insured. It also means that the roofer has passed an extensive background check and training. A roofer who is NRCIA certified can provide you with references from past clients and will be able to explain how the inspection process works. During the inspection, the roofer will look at the entire roofing system and its components to identify any issues. They will also inspect the attic and interior of your home for leaks, mold or other signs of damage caused by the roof. They will also be able to advise you on the best roofing solution for your needs, whether that’s an asphalt shingle replacement or a metal roof installation.

Roofers who are certified by the manufacturers of roofing materials have gone through advanced training with that particular company. The manufacturers then watch and oversee several roof installations and repairs to ensure that the roofer follows their instructions exactly. They also typically offer additional warranties and workmanship coverage on top of the manufacturer’s warranty.

It is a good idea to ask any roofers you are considering for a list of their manufacturer certifications and which ones they hold. If a roofer can’t provide you with this information, it might be wise to move on to another contractor.

Aside from manufacturer certifications, a licensed roofer should also carry basic insurance coverage such as general liability and workers’ compensation coverage. This is to protect you in the event that the roofing crew gets injured while on your property or they damage anything else during the repair or installation process.

Licensed roofers will always provide a written contract with details on the scope of work, the materials required and the expected timeline for the project. They will also discuss any possible alternative solutions and the pros and cons of each. In addition, they will be able to advise you on how to maintain your roof after it is installed, and how to protect against any possible warranty claims in the future.

Depending on the location, some provinces may require roofers to get a roofing-specific trade certification. In Quebec, for example, the process of becoming a certified roofer involves completing two apprenticeship periods and earning Red Seal trade certification from the Commission de la construction du Québec.
