Every month, we seek to bring our readers insight from the worlds of home construction, home repair, and home maintenance straight from local Northwest Washington contractors in a segment we call “3 Questions.” Yep, you guessed it: we ask three questions, and the contractors answer them.

This month, in our inaugural edition of “3 Questions,” we spoke with Norman Flint—owner of Timberline Construction LLC—about some common roofing questions.”

Q1: What’s your favorite type of composition roof and why?
“Architectural composition is the most universal and widely used. It has longevity and looks good on a variety of buildings.”

Q2: What are your thoughts about pressure washing roofs?
“Pressure washing roofs tend to cause more damage than benefit. Moss treatment products are best applied early. Consistent maintenance for moss is a better approach. Once the moss gets rooted, it is a difficult process of scraping and light pressure washing. It is best to address moss in the dry months when the roots of the moss are dried out.”

Q3: For asphalt composition roofs, what are the most significant issues you discover when inspecting roofs coming to end-of-life? 
“The biggest problem with any roof coming to the end-of-life is that owners wait too long to replace them. This leads to a host of issues, ranging from (roofing) blow off, leaks, water damage, and rot-related issues.”
