Do you own your own home? Have you ever given much thought to your roof? For many people, a roof isn't something to think about unless it starts to leak. Unfortunately, leaky roofs can cause significant and expensive damage. Before your roof gets to the point where it's leaking, there are often signs that something needs to be repaired as soon as possible. Some signs that you should start considering replacing your roof include:
Roof indentations: During a roof installation, sheets of plywood are fastened to the rafters, then shingles are attached to the plywood. Over time, moisture and other factors can affect the plywood, causing it to weaken and get soft. This would be obvious if you were to walk across your roof, but it's not always obvious from the ground. At first, it will be difficult to notice any differences in your roof. As time passes, however, the plywood sheets will start to buckle downward. This will be subtle at first but will become more obvious as time goes by. If any section of your roof no longer looks flat, there's a good chance that your imagination isn't playing tricks on you and you need to contact a roofer as soon as possible.
Curled shingles: Although asphalt shingles can last for decades, they do eventually succumb to the elements. On a south-facing roof, one of the first signs that your shingles are getting too old to do their jobs properly may be a slight upward curl around the edges of some of the shingles. Generally caused by sun or heat damage, curled shingles will no longer be as efficient at keeping out rain as they once were. If only some of the shingles are showing signs of starting to curl, you may be able to replace just that section instead of opting for a full roof installation.
Gravel in your drainpipe: While there are several components that make up an asphalt shingle, their color is the result of small bits of gravel being embedded in the asphalt base. This gravel helps to protect the asphalt from wear, both by the sun and by rain. But the gravel will eventually start to loosen and get washed away by rain or melting snow. This results in the tiny pebbles getting washed down into your gutters and down your drainpipe. Lacking gutters, you'll notice a collection of this gravel starting to form at the drip line along the edge of your roof. While you may still have time before your shingles are damaged enough that they start to leak and you need a full roof installation, seeing these small pebbles is a sign that you should start making preparations to reshingle your roof.
