A home’s roof provides it from protection against the weather, ranging from the baking sun during the summer to howling winds and deep snowdrifts in the winter. Even the best-quality roof won’t be able to withstand the worst winter has to throw at it if it isn’t kept in a state of good repair, though, so don’t assume a lifetime warranty means the roof can simply be ignored. Instead, read on to find out about a few warning signs of trouble to come and address them before the temperatures drop.
Asphalt shingles are the most popular roofing type thanks to their affordability and efficiency, but they’re not the longest-lasting material in today’s markets. They can only be reasonably expected to last between 20 and 25 years with proper installation and adequate maintenance. Homeowners whose roofs aren’t properly ventilated or who haven’t been scheduling routine maintenance may notice signs of premature aging much sooner.
Shingles should lie flat against the roof. If any of them are protruding, buckling, or curling at the edges, it may be time to consider replacing them. Roofers can repair the roof by replacing a few shingles at a time if one area has suffered acute damage after a storm, but if the whole roof is showing signs of wear, it’s best to replace it.
Drooping or Sagging
The home’s roofline should look straight, crisp, and level. If the middle is sagging or there are areas that droop away from the peak or edges, it’s a sure sign that moisture has permeated the shingles. This will eventually cause the roof deck to rot, so take action now to avoid more expensive repairs as water seeps into the home.
Moss and Algae
Year-round moisture places homes at increased risk of developing moss, algae, mold, and fungi growth. The earliest sign of these issues is shingle discoloration, so homeowners who notice green, gray, or white discoloration on their black roofs should schedule an inspection with a roofing contractor. The roof may also be retaining moisture, leading to spongy, damp areas, so it’s best to hire a pro to evaluate the situation instead of just cleaning the growth off and calling it a day.
