Shingle roofs generally need to be replaced once every 20 or 25 years, give or take due to weathering. Unless you have kept a record of how often the roof on your property has been maintained, you might not know just how old it is, and just how much attention it needs. If you see a missing shingle, though, it is probably indicative of an older roof.
When you spot a missing shingle, you should have it replaced as soon as possible to prevent any water leaking into the building. A little bit of water could damage the woodwork in that area, jeopardizing the integrity. An inundation carried in from a storm could flood an attic or soak into wood and supports all throughout the property, just from that one spot.
Replace One or Replace Them All?
Replacing one or two missing shingles is good but it might be better to just get them all replaced. Shingles shouldn’t be tearing off or falling from your roof unless the structure is old or there is something wrong with it. So when you take the time to replace one, you could benefit from addressing all the potential issues, assuming it is necessary.
Three things to also look for if you spot a missing shingle to replace:
- Cracked shingles: A shingle that is in bits due to cracks and breaks is essentially just a missing shingle. It is no longer doing its job to protect your home and should be replaced.
- Bouncy roofing: You should never step on your roof and feel like you’re on a weak trampoline. Bouncy steps means that moisture is trapped in your shingles and affecting the underlying woodwork. This is not good.
- Foreign objects or visitors: Is there outside debris on the inside of your attic? Did you find a wild animal in your crawlspace? A larger hole in your shingles and roofing is likely to blame.
