Installation requirements

• Installation shall be carried out by a Viking trained installer.
• Installation shall be undertaken in accordance with all relevant technical information related to the selected installation method, including information contained within the BRANZ Appraisal No. 276 (2018).
• Long term properties of the material may be affected by contact with petroleum-based products such as oils, greases and solvents.

Maintenance requirements

• Little maintenance should be required apart from the removal of lichen, moss and organic growth that may become established and the removal of accumulations of the stone granules in spouting.
• Annual inspections must be made to ensure that all aspects of the roof cladding, including the pre-finished coating, the flashings and any joints remain in a weatherproof condition. Any damaged areas or areas showing signs of deterioration which would allow water ingress must be repaired immediately.
• A water-based chemical treatment recommended by Viking Roofspec as being suitable for use with bitumen-based products must be used for the removal of organic material. Petroleum-based solvents or cleaners must not be used.

Warrantees

The Viking CertainTeed asphalt shingles system is backed by product warranties ranging from 20-50 years (depending on the profile).

Company Product Information

Environmental

• By utilising what would otherwise be waste materials, such as slag residue from oil refining, the manufacturing process of CertainTeed shingles reduces land fill waste and greenhouse gas emissions.
• At the end of their serviceable life, shingles can be overlaid (special conditions apply), avoiding the dumping of inorganic materials.
• Lighter colours in the CertainTeed range; many of which carry US CoolStar energy ratings, reduce the energy required to cool a building.
• CertainTeed asphalt shingles meet the AS/NZS 4020 testing of products for use in contact with drinking water standard, so they can be used for the collection of drinking water.
