Metal Roofing Federal Way, WA Review
Review: April 16, 2025Completion: March 29, 2010I've had 2 Interlock Metal Roofs and 2 different houses. One in 2003 and the roof still looks great - almost like new after 22 years!

Metal Shingles Federal Way, WA Review
Review: October 13, 2015Completion: October 13, 2015I was impressed with Ross Peterson's presentation of the information to us. He was very very friendly in a non-pushy way. It really is a situation so many times with salespeople where they are so eager to get a deal they start getting pushy and show frustration when you don't buy at that moment. That was not the case with Ross. He also knew we weren't in the market for another year or two. Hopefully it will all work out.
