Just so you know the Presidential Shake TL’s weigh 480 lbs a square, the Presidential Shakes weigh around 350 lbs a square and Landmark 30’s weigh 250 lbs a square.
9 bundles of starters seem high for a 30 sq roof if your just laying them on the bottoms. I run my starters up the rakes as well for the nice clean edge look and on most 30 sq roofs I use 5 bundles total at $18 a bundle with tax you have under $100 which is a pretty small expense when looking at the overall job. With Landmark shingles I use the metric starters made by Certainteed.
With the Presidentials you have to use the matching starters and ridge which aren’t cheap. A bundle of Presidential starters are at least $30 a bundle which would bring a square price to around $100. Haven’t priced the ridge but I know the Contour style ridge is $2 a foot. When laid correctly there are something in the order of 5 layers of shingles in all areas at a minumal. Keep in mind the added weight to your roof with the TL version. If your in a snow region this is important to know when building the truss system.
I thought I recalled the TL’s going for close to $200 a square but that may have been the Centenial Slates. At any rate it is Certainteed most expensive shingle they offer.
Never laid a roof with one but did do an addition with the GAF version, very fun to cut in the Winter!
