The key to longevity of shingles is proper installation, regular maintenance, and timely replacement.
However, over time, the shingles can deteriorate, become damaged, or start to show signs of wear and tear, which can result in leaks and damage to the underlying roof structure.
In this article, we will discuss the signs of aging shingles, and the steps you can take to restore the life of your shingles or replace them before they cause further damage.
Signs of aging shingles
The following are the most common signs of aging shingles:
Cracking: This is the most common sign of aging shingles. Cracks can be caused by exposure to extreme temperatures, high winds, and hail.
Blistering: This occurs when the shingle separates from the underlayment, and forms a blister-like appearance on the surface. Blistering is often caused by moisture that becomes trapped under the shingle, causing it to lift.
Cupping: This is a sign that the shingles are losing their flexibility, and becoming brittle. Cupping occurs when the edges of the shingle start to curl upward, and the center of the shingle begins to dip downward.
Granule loss: Over time, the granules on the surface of the shingle will begin to wear off, leaving a smooth surface. This can cause the shingle to become more susceptible to damage from the sun, wind, and rain.
Staining: Stains on the surface of the shingles can indicate a problem with the roof's ventilation, or a problem with the shingles themselves. Stains can be caused by algae growth, mold, and other environmental factors.
Steps to restore the life of your shingles
If your shingles are showing signs of aging, there are a few steps you can take to restore their life, including:
Cleaning: Cleaning your shingles can help to remove any buildup of algae, moss, and other debris that can cause damage over time. You can use a mild soap solution, or a specialized roof cleaning product, to clean the shingles.
Sealing: Sealing your shingles can help to protect them from water damage and extend their life. You can use a roofing sealant, which is typically a brush-on or spray-on product, to seal the shingles.
Repairs: If you have a small area of damaged shingles, you can repair them by applying a patch or patching compound. You should only attempt to repair your shingles if you are comfortable working on a roof, as it can be dangerous to walk on a roof that is not secure.
When to replace your shingles
If your shingles are beyond repair, or if they are showing signs of severe wear and tear, it may be time to replace them. The following are some of the most common reasons why you may need to replace your shingles:
Age: Asphalt shingles typically last between 15 and 25 years, depending on the type of shingle and the local climate. If your shingles are approaching the end of their life span, it may be time to replace them.
Missing or damaged shingles: If you notice that shingles are missing, cracked, torn, or otherwise damaged, it's important to address the issue promptly. Damaged shingles can compromise the integrity of your roof and lead to leaks.
Moss or algae growth: Excessive moss, algae, or fungal growth on your shingles can indicate moisture retention, which can damage the shingles over time. While cleaning may be a temporary solution, if the growth persists, it's worth considering replacement.
Leaks or water damage: If you're experiencing roof leaks or notice water stains on your ceilings or walls, it's important to have your roof inspected. Leaks can be a sign of shingle deterioration or other roofing issues that require attention. It may be time to replace your shingles. Leaks can cause serious damage to the underlying roof structure.
It's important to note that these signs are general indicators, and a professional roofing contractor can provide a more accurate assessment of your shingles' condition and advise you on whether replacement is necessary. Regular inspections and maintenance can help prolong the lifespan of your shingles and ensure the overall health of your roof.
