Reroofing with Asphalt Shingles in Winter Original Post: http://www.vikingroofspec.co.nz/blog/post/reroofing-with-asphalt-shinglesin-winter It's that time of year when we experience the stronger winds and heavier rain of winter. This provides challenges during construction and reroofing with delays and increased costs.

Below we look at three points on how the installation of an asphalt shingle roof can prevent delays, provide weather-tightness and piece of mind throughout the reroofing process.

The Reroofing Process The challenge with reroofing in winter is removing sections of the old roof and installing the new roof within the same day to ensure the building is watertight over night. The advantage of using the CertainTeed shingle system is that it contains a plywood substrate which is quick to install and when covered with a peel & stick underlay it immediately waterproofs the building for up to 6 months, even before the shingles are laid. This means the installer of the CertainTeed asphalt shingle roof, a Viking Approved Applicator, is able to remove the old roof in sections, install the new plywood and protect the building with peel & stick underlay. This can be done within a day so the building is watertight during the night.

The End Product The CertainTeed asphalt shingle system possesses the capacity to deal with winds of up-to 205km/h, which is classified as an 'extra high' wind rating. This is an obvious benefit in winter, where much stronger winds can be experienced.

The way a CertainTeed asphalt shingle system provides ventilation in winter is a key benefit of the system. In an unvented roof space, moisture generated from exposure to the elements or from within the home condenses on the cold surfaces within the roof, causing damage to insulation and framing. The Viking CertainTeed asphalt shingle system uses a proprietary ridge vent offering the most-efficient low-profile ventilation system in the market. Its external baffle design 'pulls' air out of the roof from both sides of the ridge, allowing for moisture to escape.

Without this effective ventilation, a home can encounter unhealthy consequences such as damp, rot and mould.

Above are three very worthwhile points to keep in mind when considering building or reroofing this winter. If you are considering a reroof, contact Viking Roofspec and a representative will meet you to discuss your project. Requiring a reroof can sound daunting, but is made easy with Viking's BRANZ Appraised CertainTeed asphalt shingles.
