About your attic
The key to extending the life of your roof is in your attic
As roofing, London, Ontario experts, Murray Shaw understands the role of the attic in your home’s protection system. With our help, you can potentially save thousands of dollars in energy costs and repairs. A well ventilated and insulated attic will:
- Protect your roof system from excessive heat, ice and interior moisture
- Improve home heating and cooling
- Reduce damaging ice dams
- Extend the life of your roof
The attic is the foundation of your roof. It has to be done right before the roof can be installed to our high quality standards. We can ensure that your attic is structurally sound, properly ventilated, sealed and insulated before we add shingles and seal it in.
Prevent ice dams
Ice dams can be a major cause of leaks that cause damage to your attic, ceilings and walls. They form when heat from the inside of your home escapes into the attic and warms the roof decking, causing the snow to melt. The water runs down to the eaves and refreezes, causing water to back-up under the shingles or behind fascia board. From there, the water can soak through the roof decking or wall sheathing.

Save energy, increase roof life
In the summer, a poorly insulated attic can cost you a lot of money in roof repairs and air conditioning. Hot, moist air in the attic can warp floor boards and roof sheathing, significantly decreasing the life of your roofing system. A hot attic also makes a home more difficult – and expensive — to cool.
To eliminate hot spots,:
- Ensure that bathroom and kitchen exhaust fans vent through the walls (not the roof), if at all possible
- Insulate the attic and access to the attic
- Install soffit and ridge vents in a 2:1 ratio
- Ensure that insulation is not blocking soffit vents
- Seal off recessed lights
