"Hey! How's it going? I'm [Name] with [Company] — we're working in this neighborhood today and I wanted to stop by real quick."
"A lot of homes in this area have roofs coming up on that 20-year mark — some are already showing wear from recent storms. We've been helping neighbors get it looked at before it becomes a bigger issue."
"Would you be open to us taking a quick look at your roof? Takes maybe 10 minutes — totally free, no obligation. We'll tell you exactly what we see."
"Totally get it — I'd just hate for you to miss the insurance window if there's storm damage. Most homeowners don't even realize they're covered."
"Awesome — I can get our inspector over here [today/tomorrow]. What time works best for you?"
