While a lot of people don't spend a lot of time thinking about their roof, it is a major component of your home's structure. Unfortunately, a roof can last a long time but it won't last forever, so you will need to know when to have it replaced by an experienced roofing contractor. The following signs may mean that your house needs a new roof:
It is not uncommon for a storm or strong wind to damage a few shingles on a roof-- this can typically be easily repaired by a roofing company. But if large areas of your roof have shingles that are cracked or curling, it is typically a sign that your roof has come to the end of its lifespan. If you can see some problem areas from the ground, contact a roofing company to do a full roof inspection.
It is also a good idea to check your gutters and downspouts for signs of shingle granules. In the event that the shingles are shedding the top layer of granules, it usually means that it is time for a roof replacement.
A roof that has any sagging spots definitely needs to be replaced promptly before further damage to the home occurs. Check the lowest points of the roof first for signs of sagging. If your roof is sagging in any spots, it often means that there may be wood rot or trapped moisture.
Moss or Mold Growth
Greenery may look great in your yard, but if you see green on your roof it is probably in trouble. Moss or mold on the roof may not seem like a serious problem, but in many cases it is. Mold and moss typically only grow in large amounts on a roof when there is a lot of trapped moisture under the shingles.
Some homeowners try to remove moss or mold by cleaning the roof, but this is typically just like putting a bandage on the problem. If there is enough moisture trapped in your roof to promote the growth of mold or moss, it is a good idea to have a new roof installed.
A small leak after a big rain storm is not a reason to panic, but if you have large leaks in several areas of your home it may be a sign that the roof is no longer structurally sound. In addition to active leaks, watch your ceiling for signs of water damage and go up in the attic during the day to see if you can see sunlight through any cracks in the roof.
