There are certain signs to look for when a roof needs replacing. Various factors lead to roof damage such as mildew, mold, and weather, which can cause leaks, sagging, and cracks. Another thing to consider is your roof’s age. If it’s over 20 years old, there’s a good chance that it needs replacing.
Curling Or buckling shingles
Shingles that are curled or buckling is one of the first signs that a new roof needs to be installed. Typically, curling shingles occur due to aging, moisture, and excessive heat. In addition, poor installation is a common cause of buckling and curling. Shingles that are curled or buckled are vulnerable to wind and ice damage and can easily crack or break off due to their rigidness.
Broken or missing shingles
Broken or missing roof shingles are also a telling sign that something isn’t right. Broken or missing shingles are generally caused by extensive wind damage. They can also be a sign of rain and snow damage and leakage. Check the valleys for signs of damage. If the shingles are missing or broken, most likely the roof will need replacing.
A sagging roof is a sure sign that the roof is damaged and needs to be replaced. Long-term water damage is typically the cause of a sagging roof. Another cause is too much weight from ice and snow. To check for signs of sagging, look at the roof line. It should be straight. If there is a dip, swag, or curve present, the roof is sagging and will more than likely need to be replaced.
Check the flashing for signs of damage such as lifting, separation, and dried and flaky caulking. Flashing is located around the chimney, eaves, stacks, valleys, and skylights. The lifting or separation of flashing is caused by normal expansion and contraction of the roof. Due to the expansion and contraction, the fasteners become loose and can allow water to seep into the house and cause damage.
Look for large amounts of shingle granules in the gutters. When roofs age, bare spots can form, which causes them to lose more granules. Granules can also be a result of poorly designed valleys and a poorly placed downspout. Shingle granules are dark in color and look similar to sand crystals. Granule loss can accelerate the aging of the roof and can cause shingle decay, so this problem should be addressed immediately to stop moisture from entering the house.
When any of these signs are present, it is a good indication that the roof needs replacing. It is highly recommended that a roof repair professional is consulted to address these problems because ignoring them could lead to further, more costly damage.
