At Reliance Roof Pros, roofing in the Northwest requires focus and science to get the best possible result. Industry statistics show that for every new roof installed, there are 5-6 repair jobs that are performed. People do not repair worn out roofs—they replace them! This means that the minimum ratio of roofs that require work before they are worn-out is 5 to 1. We want to help you receive the information needed to make a wise choice to avoid the pitfalls of our unique environment. It is a sick feeling to know you spent good money on a bad result. The Northwest region (Oregon and Washington) is one of the most challenging environments for roof performance and roofing services in the world. We have a number of factors that create tremendous stress on the waterproofing and roofing integrity of our homes and buildings. The metro areas of the Northwest have about 40 inches of rain a year, mostly compressed into 8 months. We have heavy tree debris and moss. We have cool/cold temperatures with heavy moisture/high humidity, leading to a mold and mildew growing environment which affects the underside of the roof, and encourages rot in the wood supporting the roof. Because we do not have a lot of snow load, our homes are built lighter and with lesser roof slope than other homes throughout the northern United States. We also had a large “tech boom” building phase in the 90’s that led to some sub-par construction methods that we are still paying for.
