This looks pretty much like a standard architectural or dimensional shingle but has some hidden technology hiding. SBS is a modified polymer asphalt giving shingles greater flexibility and crack resistance. Additionally this lead to the shingle being rated CLASS 4 impact resistant - so if you live in a hail zone it may be for you. There are quite a bit of colors available still. You won't find this shingle anywhere thought as Certainteed limits the availability regionally.
