Yesterday in the Tri-Cities, I saw three new roofs being installed incorrectly (and no, it wasn't us at SCR Exteriors!).Shingles shed water, but they are not a total waterproof barrier. Without the right backup, vulnerable areas like eaves and valleys will leak when ice dams form or heavy rain hits.That is why CertainTeed requires fully adhered, self-adhering waterproofing underlayment in these critical spots to protect your wood deck.We always do it right the first time. Call SCR Exteriors today at (423) 384-4727 to protect your home.
