Anderson Construction came out to my home to provide an on-site estimate for a minor repair to my metal roof the day within 24 hours of my request.
He confirmed the source of a leak (base of an old dormer), and used some caulk I had on hand to do the repair. Then would not let me pay him for his time.
While he was on the roof, he also did an inspection and identified a problem area I would not have spotted from the ground (took phone pics for me), and made some recommendations for general maintenance to extend the life of my now 20 year old beach-side roof.
Knowledgeable, professional, responsive = highly recommended.
