When I first heard the noise it reminded me of tree branches scraping the roof. Which worried me. We don’t have trees close enough to scrape the roof. Knowing this did little to quell the fear of having to replace another roof due to trees. Did I mention there was a thunderstorm outside? Right. Upstairs, in my office with no windows, it sounded like trees on the roof, but the closer I got to the patio door I realized trees were the least of my worries. Snow? Hail!
