Asphalt shingles are individual bituminous sheets (usually 915mm long), nailed on top of a timber-sarked roof substrate with either a layer of bitumen felt or self-adhering membrane in-between. The 'shingled' (overlapped) method of shingle installation, provides maximum watershed and the ridge-vent system on the roof's apex ensures the building is adequately ventilated.
Viking's CertainTeed Asphalt shingles are composed of a strong fibre-glass mat base. Asphalt is applied over this and ceramic-coated mineral granules are embedded in the water-resistant asphalt. These ceramic granules provide UV resistance and come in a wide colour range. CertainTeed asphalt shingles have proven their durability by withstanding extreme conditions in New Zealand and the Pacific Islands over the last 25 years.
