My wife and I bought a 'heritage house' in Nepean a few years ago and, on the recommendation of a neighbour, decided to replace the aging shingle roof that had been there for 25+ years.
After getting estimates from a few different companies (prices ranged dramatically!) we settled on Godfry Roofing because they appeared to be the most professional and trustworthy. The guy we spoke to on the phone (Mike I think) was polite and explained the costs and the work that was required etc.
Granted, i have low expectations of roofing companies based on past experiences, but we were extremely pleased with Godfrey and the new roof looks great. They finished the job in just a couple of days, and the workers were quiet and seemed professional. they didnt leave any mess, and there was no giant metal bin in our driveway like some of our friends have had when they had their roof replaced.
All in all, very pleased with Godfrey roofing, and definitely recommend them if you need to get roofing done in Ottawa.
