Cedar Roofing

Another natural beauty in roofing is cedar roofing. With rich texture and color, cedar roofing is a unique addition to any home. Cedar roofing is also naturally durable and long-lasting. The natural oils and tannins in cedar resist insect attack, and also act as a rot repellent.

Cedar has the highest insulative value of any building material, and in fact, is the only one with an “R” value. Tests show that a cedar roof can save you up to 20% off your heating and cooling costs, due to its thermal efficiency. The cells in cedar allow them to act as an insulator naturally. It has been tested to withstand 130mph, hurricane force winds, and pounding hailstorms.

We needed new gutters but we kept putting it off because there was always some other project that needed to be done first. Until we started noticing damage from our gutters not draining properly. Along comes Scott to our rescue! He showed us the problems, explained how they would fix it, and before our next thunderstorm our gutters were right as rain! Thanks Dunsmore Exteriors!
