“How long should my roof last?”
It is the most common question we get at Cornerstone Roofing. If you look at the marketing brochure on a bundle of shingles, it might say “25 Years” or even “Lifetime Limited Warranty.” But in the real-world laboratory of Middle Georgia, those numbers can be misleading.
We follow the “15-Year Rule.” In our climate—with its unique mix of high heat, high humidity, and severe storms—an asphalt shingle roof typically begins to reach the end of its functional life between year 15 and year 20. If your roof was installed around 2005-2009, you are currently in the critical decision window.
