Sander Scott compares two roofs: a 10-12 year old one that looks shot, and a 30-year-old one that looks new. The difference isn't the shingles. It's that one homeowner actually cleaned it. Regular maintenance, especially keeping your roof clean, adds years to its life.
We often, I tell this story often to my clients, that it's not uncommon for us to go on a roof one day and it will be like a 10-year, 12-year-old roof, and the roof looks terrible. And then we'll go down the same day, different roof, different home, a 30-year-old roof, looks like it's brand new. And it could be shingle manufacturer to a certain point, but most of the time it's because one homeowner maintained their roof and kept it cleaner.
