Cracked, curled, or missing shingles can be a sign that your roof needs some love. Sometimes, these issues are localized and can be fixed easily. But if your morning jog around the house reveals more and more problem areas, this could indicate a deeper, more systemic issue. Think of it like this: if you're constantly patching your roof, it's like using a small umbrella to try to stay dry in a hurricane.
Water stains on your ceilings or walls inside your home are also tell-tale signs that your roof may be failing. These leaks can lead to mold, mildew, and a whole host of other issues that you definitely don't want to deal with over breakfast. If you're setting out buckets every time it rains, it's probably time to consider a replacement.
