When to Repair vs. Replace

If your asphalt shingle roof is under 15 years old and damage is isolated (under 25% of the surface), repair makes sense. If the roof is 20+ years old, granules are washing into gutters, or you have widespread cracking, replacement is more economical than repeated repairs. A reputable roofer will give you an honest assessment — get three quotes. (Serving North York, Ontario.)
