Fiberglass Laminate Shingles

Asphalt Shingles in North Vancouver

If you are thinking about a new asphalt shingle roof and want the full protection offered by a shingle manufacturer’s warranty, then you face the following challenge:

Hiring a roofing contractor who is capable of designing and installing a roof system in accordance with a manufacture’s specific warranty requirements.

The warranty period offered by the shingle manufacturer, whether 30, 40, 50 years or even lifetime, is based on shingle performance when tested under the conditions defined in their installation requirements.

Inadequate and unbalanced soffit to roof ventilation is the most frequently ignored or misunderstood requirement for material warranty.

Shingle manufacturers cannot be held liable if the contractor installing the shingles is not aware or chooses not to install the shingles in accordance with the manufacturer’s installation requirements.

At Westcoast Roofing Systems we install to manufacturers’ requirements. Westcoast has the rare distinction of maintaining the highest level installer certification for a number of major roofing material manufacturers, including CertainTeed and GAF.

Tip

Converting a cedar roof to an asphalt roof is not always recommended.

The plywood underlayment and asphalt shingles reduce the breathability of attic cavities causing the relative humidity in the attic cavity to increase. This risk of condensation, the leaky condo syndrome, must be managed by introducing the appropriate amount of soffit and roof ventilation in accordance with BC building code. This modification in ventilation cannot be achieved in all cases, meaning not all cedar roofs should be converted to asphalt roofs.
