Project Progress: Hamilton residence -

The new shingle roof was installed at the Hamilton residence in Maitland last week. The shingle is from CertainTeed and was installed by Collis Roofing. The color called Silver Birch has a high-reflective value and achieves an EnergyStar rating because it saves energy by keeping the attic cooler.

The low slope of the roof (2/12) mandates that a peel-and-stick underlayment is installed as a secondary waterproof barrier. Essentially the shingles protect the membrane underneath and will provide a leak-free roof years beyond the recommended normal life of the shingles themselves.

Another challenge we faced was the exposed T&G decking under the roof overhangs all the way around the existing part of the house. In the photo above, the new overhangs on the addition are shown, but in this case plywood roof decking is added on top of the T&G creating an overall thickness of 1-1/4"; enough to keep the roof nails from poking through. This was not the case on the existing part of the house where the original T&G had roofing applied directly on top of it. For the existing part of the house the roofers used a special shorter nail and had to add more nails per shingle in order to meet the building code requirements and prevent blow-off.
The special efforts will all seem worthwhile when the project is completed, if it's difficult to determine what is new and what was existing. We hope the completed project will look like a fresh update of a mid-century home that the original designers would be pleased with.
