We had serious roof and chimney issues, and the tiles were icy. OSI eliminated the potential danger with a Winter outdoor inspection and saved us a lot of money. I wanted to reach out and express our gratitude for your before and after aerial photos and video. They helped to show grantees what we needed Grants for and demonstrated a good use of funds. The imaging was crystal clear and was very helpful to our mason. It also brought issues to our attention on our tile roof peaks. Thank you for your services.
