Certainteed has just came out with a new, revolutionary shingle called Patriot AR. At first glance, it might look like a Certainteed New Horizon or Owens Corning Prominence from years ago. Why does it remind you of one of those shingles? Patriot AR gives you a dimensional look with a slap, non-laminated shingle. The big difference between this shingle and those older slab shingles is it doesn’t take a second granual drop to create the dimensional look. In the old days, a second granual drop would cause cracking in the shingle. Now that Certainteed has perfected the dimensional look on a slab, they’ve got a truly revolutionary shingle they can offer.
You can read what John Reese has to say about why you you need to start using Certainteed Patriot AR instead of a 3-Tab shingle here. Basically, what you need to know about Patriot AR comes down to these bullet points:
First, you should never rack this shingle. Because of the variation and style, Patriot should always be stair stepped and not racked. Second, always chalk horizontal lines at least every 4 courses (that’s 22 1/2″). Third, ALWAYS put 4 nails below the seal strip. Yes, you might get a few shiners, but just touch them up with a some caulk and sprinkler some granuals on them. A few shiners is a sign of a good roofer.
