Asphalt roofing is one of the most common types of roofing materials that you can find on the market, largely because of its low price point, relatively easy installation, long lifespan, and durability. However, no roofing material is invincible, and the variety of weather conditions that your home's roof experiences throughout the year will quickly take a toll on your asphalt shingles. Understanding the warning signs associated with asphalt shingles that have begun to deteriorate can help you determine when you should talk to a roofing contractor about replacing your roof before leaks and other complications can arise.
While it may be hard to spot from the ground, you should be able to tell what condition your shingles are in when you are cleaning the gutters out. Shingles should lay flat over one another. Over time, as they expand and contract due to temperature changes and are exposed to heavy moisture, shingles can begin to curl upwards. This allows for water to get between them and loosen your shingles from your roof, while also allowing water to seep into your attic.
2. Black Grains
Another thing to look out for when cleaning your gutters, even if your shingles appear to be flat and in good condition, are black granules spread throughout the gutters and around the base of your downspout. This happens when shingles have been exposed to a significant amount of rainfall, sunlight, and friction, which causes their top layer to literally break off. This degrades the overall structural integrity of your shingles and makes it more likely that they will crack, curl, or otherwise fall apart and allow water to enter your home. The greater the amount of black granules you find, the more serious the problem and the quicker you should begin the replacement process.
3. Sagging Sections
Finally, the last and surest sign that you are overdue for a complete roof replacement is if you notice that there is a section of your roof that has begun to sag inwards. Any sort of misshapen roof will allow water to begin to pool, and stagnant or standing water on your roof represents a massive drainage issue and a potential for water damage within the interior of your home. In this case, not only will you likely have to replace your shingles, but you may also need to have new roofing trusses and supports installed in the damaged area.
