The roof over your head is the most important component of your house. It keeps your family safe from the elements, and your house dry and mold-free. You do not want to entrust your roof installation to just anyone.
At Principal Roofing and Exterior Contractors, only highly-skilled tradespeople and roofers will be completing your project. We ensure that the roof is installed correctly with our on-site training program, where each roofer is trained on our installation methods to ensure that there are no corners cut. Ask us about the little extras we do to make sure the water stays out!


At the end of the project, your roof is inspected at completion to ensure that there are no deficiencies or oversites and that your roof will be prepared for whatever weather is thrown at it. Our goal is to never have to attend your home again and using only high-quality materials ensures your roof will last.

How much does re-roofing add to the property’s value?

An inspection of the roof by an expert is necessary to gauge the quality of the roof. The damages, if not fixed, will lower the value and might even cause the buyer to back out of the deal if they have to pay for pricey roof upkeep and repairs. A leaking roof can also cause mold in the inside of the house, which can be very costly to remedy. This can completely turn off buyers from purchasing your property.
A well-maintained house will always win the hearts of buyers over ones that need major repairs.
