Surrey's Source for Asphalt Roofing and Cedar Shakes and Shingles

At Stoney Cedar Ltd., we’re committed to carrying the best quality products in the industry. While some other suppliers may carry the same brands, no one carries them better and offers you more reliable information and advice about what types of products will suit your specific application.

Q. What is the difference between a cedar shingle and a shake?

A. The most significant difference is the amount of exposure. An 18" shingle is applied at 5½" to the weather while an 18" shake is applied at 7½" to the weather. Shingles applied at 5½" become a 3-ply roof which means that there are three layers of shingles at any location on the roof. Shakes are 2-ply. Shakes are layered with felt between each layer, thus having two layers of felt at any location. No felt is required between each layer of the shingle application. Another difference is shakes have a split face, which gives a rustic appearance. The exception is the taper-sawn shake, which looks like a thick shingle.

Q. Does a roof need felt?

A. Yes, building code regulations require the use of 30lb. felt along the eave line for both shakes and shingles, plus 15lb felt for the interlayment with shakes.

Q. I’ve heard that felt doesn’t allow the shakes or shingles to breathe, causing them to rot underneath. Is this true?

A. No, that is not the case at all. Inadequate ventilation in the attic is what causes the underside of a roof to sweat and eventually rot. A well-ventilated attic will not only add many years to the roof, but it will also keep your home cooler in the summer. Most homes are too airtight. Good ventilation will make it more comfortable all year-round.

Q. What is CCA treating and is it safe?

A. Shakes and shingles are placed in a vacuum retort. Then with pressure, a treating compound mixed with water is inserted in the wood at 200 lbs. per square inch. The CCA pressure-treated roof is not harmful to humans, animals or vegetation. CCA treated shakes and shingles will not grow moss, an important factor in British Columbia. The CCA treatment also carries a 30-year warranty against rot.

Q. A cedar roof is more expensive than it used to be. What do you think of an alternative, such as Duroid?

A. First of all, Duroid was a brand name on an organic backed asphalt shingle and it is no longer available. Asphalt shingles with a fiberglass mat are an excellent alternative. An added advantage is that they carry a Class A Fire Rating. The 20-year fibreglass asphalt shingles cost approximately 25% of the price of the least expensive cedar. The 40-year fibreglass asphalt shingles are less than 50% of the cost of the CCA treated 30-year cedar roof.
