Campbell roofing replaced my older 3 tab shingles with the new IKO Dynasty Line shingles... a little more money but guaranteed to up to 250Km hr winds. They did a great job at a reasonable price, the workmen were friendly and considerate of us as well as our neighbors... they did a good job cleaning up afterwards and went the extra mile to insure nothing was damaged in the driveway or yard when they were doing the job. I would highly recommend them!
