There are several different signs that a homeowner should look for when asking the question “is it time to replace my roof?”. Here’s what you should look for:
If you have curled, buckled, or missing shingles, it’s a sign that your roof’s durability is starting to fade. Buckled shingles can occur because of moisture in the attic space forcing nails to push up and out of the roof’s decking. This may put the interior of your home at risk to exposure of unwanted outside elements, as well as lead to shingles blowing off in high winds or during a storm.Missing granules are a sign that your roof is rapidly losing its weatherproofing properties. To check to see if you are missing granules, check your gutters for granule build up.
Take a look at the exterior of your roof. Are there any stains, discoloration, or patches of algae? Tar Streaking stains and Algae growth is caused by bacteria eating away at the shingles. Some shingles companies will take the cheap and easy way out by using fillers such as limestone, which is fairly easy for bacteria to eat through. This leaves your roof vulnerable to weather damage.
Be sure to pay attention to the environment of your attic. It is important to pay attention to temperature differences, look for moisture or mold, and be aware of any light from outside making it’s way through your roof. Your attic temperature is supposed to be consistent with the outdoor temperature. Your attic should have sufficient ventilation that circulates air in and out of the attic. If your attic is not ventilated properly, this can cause mold to grow, thus compromising the structural integrity of your roof decking. If light from outside is visible through your roof decking, it’s a sure sign that it needs to be replaced. Gaps in roof decking give moisture and other elements pathways into your home.
If your chimney is leaking or if there are any other leaks throughout the span of your home, this could mean your roof and / chimney flashing has been compromised.
Lastly, if you are experiencing an increase in heating or cooling bills, it could mean your ventilation isn’t functioning as it should. If your roof is in need of replacing, oftentimes interior energy will escape due to poor ventilation, which results in running energy higher and losing money. These are all things homeowners should be aware of.
