For an aesthetically pleasing roof it’s hard to beat Cedar Shingle Roofs. When a cedar shingle roof is first installed it has a light brown colour but after time this will change to a light grey colour. Cedar shingles are machine made and have the same thickness but can vary in width and have a smooth surface. Having a cedar shingle roof is great for insulation too, because their natural wood fiber acts as a layer of insulation, preventing heat escaping in winter and keeping cold air in summer. This gives you a beautiful looking roof while saving heating costs.
Compared to other materials used for steep roofing, cedar shingles are more resistant to hail damage and wind blow off. As long as they are installed as recommended, they can withstand wind speeds of more than 160 mph. They provide good surface adhesion, therefore having a higher resistance to snow sliding off as compared to most other materials.
Cedar shakes and cedar shingles are either CCA treated or not CCA treated. CCA stands for chromated copper arsenate. CCA is a preservative that inhibits the growth of mildew, mold and fungus and helps keep insects from eating away your beautiful cedar roof. CCA cedar can make your roof last longer, but CCA is NOT A FIRE TREAMENT. Cedar that has been fire treated is available, but your roofer will have to special order it. CCA treated cedar normally cost 15 – 20% more than non-CCA cedar. Most cedar roofs are not CCA treated.
MAINTAINING YOUR CEDAR SHINGLE ROOF
Installing a cedar shingle roof is a long term investment as they may last anywhere between 15 and 40 years. Their longevity depends on several factors, including climate and the roof slope. In general, a steep roof will allow less damage because the slope prevents rain and snow from gathering and causing damage to the wood. A flat, less sloping roof may allow elements to build up and cause added weight to the roofing structure. Excessive weight is not good for the structure and may cause a lot of problems, including the need to do an entire roof replacement.
Installing cedar roof shingles will give the home a natural covering, which can last for many years. Because wood is designed to withstand various types of weather and other natural occurrences, installing cedar roof shingles will require very little maintenance as the years continue. However without proper and constant care, cedar shingles tend to deteriorate. They are vulnerable to several kinds of molds and insects. Every six months you should make sure there are not any loose shingles or other issues that can cause problems for your cedar shingle roof.

Although shingle roofs are easier to install, due to the need for tools, carpentry skills, ventilation and weather considerations, roofing a house with shingles is best left to professionals.
