CertainTeed does not back up the manufacture of its Pacific Blue Monogram siding with a meaningful warranty. The siding failed on my house where it literally melted and bucked in. The CertainTeed sales rep has tried to blame the problem on windows that reflect the sun but this siding is on an adjoining wall, and the damage extends above the windows. The CertainTeed sales rep is not even willing to come inspect the damage reported by the contractors I used. I should have stayed with siding and painted it. Don't ever buy this siding because it is tood dark, absorbs the heat, and will never be supported properly by CertainTeed.
