The product you choose for your roof shouldn’t be taken lightly, nor should you just choose the cheapest option. A roof system is an investment that can increase the value of your property. We have a wide selection of options so that you can make the best choice for your property.

Please find below some of the products we feel are best for our clients.

Certainteed Landmark ®

The Landmark series is our best selling shingle, with good reason: entry level price, lifetime performance and brilliant colour selection just to name a few.

Certainteed Landmark Pro ®

Landmark PRO builds on the quality of the regular Landmark with more weight per square and vibrant Max Def colour blends to enrich your home’s appeal.

Certainteed Landmark
Premium ®

Landmark Premium uses a double layer technology to create a thick, dimensional shingle that is 30% heavier than traditional laminates.

Certainteed Highland Slate ®

Highland Slate’s 4-tab single-layer design offers a unique aesthetic at a fraction of the cost of real or composite slate. Colour blends are uniquely engineered to accent the exterior of your home perfectly whether stone, brick or siding.

Certainteed Grand Manor  ®

Grand Manor’s double layer engineering matches its elegant design to bring a style to your home and earn it place in CertainTeed’s line of Luxury shingles. Grand Manor best compliments natural stone, brick and stucco exteriors with colour blends that provide depth and character to match.

Certaineed Presidential Shake ®

Presidential Shake and Presidential TL are the heaviest shingles available on the market. With a pattern and dimension that replicate off-set wood shake, these shingles are the perfect compliment to timber frame or log home design without the cost or maintenance of real cedar.
