The roof of a house is one of its most important features, as it is the first line of defense against the elements. A strong, sturdy roof is a must for protecting the home’s interior and its occupants from water damage, pests, and other hazards. Unfortunately, roofs do not last forever and eventually need to be replaced.
Knowing when to replace a roof can be tricky, but some telltale signs can help determine if it’s time to invest in a new roof. This article will look at seven telltale signs that your home’s roof needs to be replaced.
1. Missing Shingles
Missing shingles can leave your roof vulnerable to water and other elemental damage. As water seeps into the crevices caused by missing shingles, other roof parts can quickly become compromised. You can also check to see if any shingles are buckling, curling, blistering, or cracking; these all indicate that your roof needs to be replaced.
2. Uneven Roof Surface
If you spot waves, ridges, sags, or dips in the surface of your roof, it may be aged beyond repair. Unevenness indicates the presence of unstable structures that can no longer hold up the weight of a roof. Look around your home to check for signs of bowing or leaning walls, which are additional warning signs that you need to replace your roof.
3. Water Stains
Water stains are caused by water seeping through your roof and onto the surface of your home. This not only makes your home look less attractive, but it is also extremely damaging. Water stains can lead to mold and rot within the walls, which can be expensive and difficult to repair. Look for water stains and check your roof as soon as possible.
4. Excessive Algae Growth
Algae can grow on any surface, but you should take special note if it grows on your roof. Excessive algae growth usually indicates that your roof is old and deteriorating.
The algae are attracted to the moisture in your roof, which can lead to further damage. Check for any noticeable algae growth and have an experienced roofer inspect your roof as soon as possible if you spot any.
5. Excessive Age
Your roof will eventually reach a point of deterioration due to exposure to sun and weather. However, the age of your roof can directly affect its future lifespan.
If your roof is 20 years old or older, you will likely need to replace it. The elements can cause severe damage to your roof over time, and replacing them could make a big difference in the overall integrity of your home.
6. Daylighting
Daylighting occurs when light can be seen through the surface of your roof. This indicates that your roof is not doing its job properly and should be replaced.
Daylighting can occur due to the presence of broken, cracked, or damaged shingles and a lack of insulation. Inspecting your roof for daylighting is the best way to determine if you need a replacement.
7. Sagging Roffline
Sagging is caused by a structural weakness, which an old or leaky roof may cause. If you notice that the roofline is sagging, the framework beneath the roof is no longer stable and could collapse if left untreated. Have an experienced roofer inspect your roof for any noticeable defects and have it replaced if necessary
