Price Increases Effective March 1st 2011 (1):
"Well folks price increases (as much as 5% to 7%) are in effect as of March 1st on the following products: GAF Shingles, all polyisocyanurate products, Poly ISO 1, and Poly ISO 2 Insulation, TPO membranes and accessories, excluding sealants and adhesives. If you are planning a weatherization project I recommend doing it prior to the increases to save some $$$. More information to come on GAF, Mulehide, Carlisle or ASC websites as official notices haven't been posted yet."
When one increases, all others usually follow suit!!!
