I have 34 years of experience, and specialize in the field of sloped roofing with specific knowledge in the areas of asphalt shingles, slate roofing and moisture, ventilation issues. I have published on such topics as roofing, ventilation and general home repairs. I view the the home holistically. I stated in roofing, but realized that roof problems are often related to basement/crawl space issues, HVAC conditions and many other factors. I’ve never stopped studying how these factors work together to affect the home. I have a recognized expert in tracking down and finding extremely complex leaks in buildings.
