Residential Roofing

When it comes to replacing your roof, quality is paramount as it’s your roof which protects your greatest asset. At Gauthier Roofing and Siding, we have a team of factory-certified residential roofing specialists.

A quality roof is much more than some shingles and nails, it is the proper integration of the many different components which truly make a “superior roofing system”.

From the design to the completed product, we will walk you through the entire process step-by-step, so the finished roof not only meets, but exceeds your expectations.

We have both 5” and 6” seamless aluminum sizes in an array of colours. We utilize heavy-duty, screw-type aluminum hangers. These hangers are concealed and secured with special rubber-washer, bolt head screws. Plus we use oversized downpipes for better drainage.

We also offer eavestrough covers also known as “gutter guards” to cover your new or existing eavestroughing, eliminating the need for cleaning. When you choose Gauthier Roofing and Siding for your eavestroughing, you’re guaranteed a system that’s second to none.
