Seal-it came to our house and explained in detail the work that they would do and what was covered in the price. They arrived when they said they would, completed the work when they said they would, and charged the amount they said they would. Our roof look much better and more importantly over the last 4 years has maintained its appearance and performance. I expect that the 10 year additional life
Seal-it said would occurr will in fact happen. Their employees were careful and thorough. I even had a neighbour comment on their workmanship.
Seal-it "Walks their own talk" I would recommend them to anyone who has a cedar shake roof!
