The roof that adds beauty to the house and protects you from natural elements needs routine maintenance to increase its lifespan. But the best maintained and designed roof will also reach the end of its lifespan. If your roof is old and is damaged it might be the time to get a new roofing rather than spending money on getting it repaired. The signs of ageing of the roof are cracked, curled and missing shingles, leak in the attic, staining along the exterior wall, clogged vents, areas where the deck appears to sag, excessive moss or other biological growth, stains on your ceilings or on interior walls, granules from shingles collecting in gutters, missing or damaged flashing, or open seams or joints.
These could be the sign of danger and there is a need to consult roofing canton MI. The roofing contractor can analyze the condition of your roof and will let you know the exact life of the roof and will help you decide if repairing the existing roof can solve your issue or it will be better to get a new roof. A normal asphalt shingle roof has a maximum lifespan of 20-30 years. If your roof is 25 years old and demands high maintenance and the expenditure of getting it to repair cost big, it will be better for you to get a new roof. Even if your roof looks good from the outside, there could be a problem.
If shingles are curling
Shingles curls in two ways cupping and clawing. When the edges of the shingles turn upwards it is cupping and when the edges stay flat and the middle starts to come up it is clawing. Both the curls are signs of leakage and damage. Depending on the intensity of curl the life of the roof will be anywhere between one to five years.
If shingles are missing
If the shingles are missing you can replace it with new shingles or can keep patching until a bigger issue comes up. It is highly recommended to get the condition of your roof checked before getting the replacement done. It might be possible that replacing the shingle will work but if there would be other damages also it will be a better option for you to get a new roof.
Leak/hole on the attic
A hole on attic is not a good sign as the sunlight, rain, and snow all can get a way through it. Small leaks can be patched, but larger ones, structural damage, and the age factor might make it wise and cost-efficient to replace the roof sooner.
The entire roof is shagging
A sagging roof is dangerous and is the indication of structural issues. It can be due to the decking in the attic or, with the supports in the foundation. You immediately need to call a professional and get a new roof. But such conditions can be avoided if you will take care of the issues when they are small.
Most of the signs are dangerous and will need a replacement if not now then after a few years. The professional always recommend getting the roof renovation done before the condition gets worse.
