Jim, I suggest you go for pressure treated Cedar, since Cedar is a stable wood and It does not warp, or shrink, or crack but can be expensive when compared to PT Pine .

I've read that the humidity can have a much greater effect on pine than cedar so that using pine in dry climates is better. I'm guessing Atlanta is humid though, so cedar would be the choice for that climate.

Hello Jim, Cedar is the old way to go. Over time all wood will warp and break, as well it will decay. Cedar has been used for 100s of years as a roofing product. The traditional material of choice would be western red cedar, But cedar roofs require maintenance and periodic cleaning, application of mildicide in certain conditions and, like most wood species, today's cedar just isn't as tight-grained and long-lasting as the stuff our forebears got to use. Ironically, the southern yellow pine that our new shingles are made from is the quintessential modern tree: grown on a plantation, 25 to 50 years old, with wide growth rings, It is, however, a stronger wood than cedar, making it tougher in hail and high-wind conditions. To overcome the wood's tendency to cup and split, the manufacturer has impregnated the shingles with a water repellant. To protect it against rot, insect attack, fungus, mold, and mildew, the wood is 100-percent saturated with chromated copper arsenate (CCA) preservative. The company also offers, and is moving toward solely offering, the more-benign but equally effective ammoniacal copper quaternary (ACQ) preservative. The result is a shingle that the company warrants against fungal decay, rot and termites for 50 years, which is 20 years longer than the highest-rated red cedar roofing. Western red cedar is around $880 a square. The pine shingles retail at around $185 per square (at 5 inches exposure),

To HD: Are you comparing the pine to pressure treated cedar? I haven't seen prices per square that high for cedar or that low for pine.

If you would like a shingle that lasts longer, then there are some composite shingles available as well.

Hi Jim, The $880 price also includes covering the entire roof in bituminous membrane and a three-dimensional nylon mesh that allows air to circulate underneath the shingles and labor. I use estimates from work done over 6 years ago in Sky valley, North Ga. mountains Sorry about the mix up. With shingle as with all building supply's the price drops based on order size. Today's current pricing in Georgia. Red Cedar $209 per square $2500.00 min, order. PT Pine shingles $ 197 per square $ 2500.min order. bituminous membrane W.R. Grace 36. x 75 ft. Grace Ice & Water Shield $135.00 Roll Three-dimensional nylon mesh $4.98 - 5.43 / Meter, Minimum Order 500 Meter.
