Federal Way, WA Metal Roofing Review: 22 Years of Interlock Roof Durability, Curb Appeal & High Resale Value

Federal Way, WA

Tim D.

I’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! The other, after we sold & moved to a new house in 2009 we went with Interlock again. The durability, warranty, and the good looks of the Interlock is why we paid the extra cost. It certainly paid off when we sold the old house – we had multiple bidders and the house went above asking – this in 2008 when real estate was not selling well. Here at the new house our neighbor was just over talking about roofs. He said it wanted to get a metal roof, and I said “yes, they are great. Our roof is metal”. He said “no way, that’s a composite roof isn’t it?” He couldn’t believe it could look so good, and still be metal – and he was 20 feet from it. Our other neighbor is on his second roof already – he could have paid for a metal roof and had triple the life left – and probably paid less! I highly recommend Interlock. Stellar installation service, great attention to detail, clear explanations, and careful aftercare. You can certainly find a cheaper roof, but you can’t beat the quality and longevity.
