Does anyone have firsthand experience with getting a roof redone under the warranty? I have 25 year BP asphalt shingles that were installed 10 years ago, on a rental home, by a large, reputable Edmonton roofing company. The roof is leaking in at least 3 places. The water is dripping through the roof itself, and not at a flashing or plumbing stack or other penetration. I have all the paperwork. According to the warranty, at their choice, BP will either pay 15/25 of the cost of redoing the roof - materials and labour, or they will pay me 15/25 of the cost of the original roof job. (15/25 because that is how much of the shingle warranty is left). Has anyone been in the same position and gone through the process? How did it go?
