The best way to find out whether your asphalt shingle roof needs replacing is to have a professional roofer carry out an inspection. That being said, there are certain signs that you can look out for that might indicate that it is time to get an inspection carried out.
Granules Missing From The Asphalt
If you can see dark patches on the shingles, then this may be a sign that the granules have fallen off. You will probably also find some granules in the guttering. The granules play no part in waterproofing the roof so you should have not any issues with a leaking roof. When the granules are missing though it can leave the roof vulnerable to other damage, so a repair will be needed as soon as possible.
Shingles Starting To Curl
When the asphalt in the shingles starts to dry and shrink, it will cause the shingles to curl. This is a problem that cannot be repaired and the shingles that are affected will need to be replaced. Shingles that have started to curl become brittle and they are more likely to blow off in high winds.
The Presence Of Moss On The Roof
A small amount of moss on the roof will not usually be anything to worry about, and it can be cleaned off.
However, if there has been some moss there for a long time, or if there is a large amount, then damage can start to occur. Checking the roof for moss on a regular basis is recommended because it is something that can be easily removed before it does too much damage.
The Age Of The Roof
General wear and tear mean that shingles on the roof are more likely to need repair or replacement the older they are. The average lifespan of a roof is 14 years, and if you have had the same roof for over 20 years, then the chances are that you will need a replacement sometime shortly.
While age is a factor to look at when thinking about roof repair, it should not be taken in isolation. If your roof is approaching 14 years old but is not showing any other problems, then you may not need any work carried out on it just yet. You may want to make your checks more frequent to increase your chances of finding a problem early.
Shingles On The Floor
This is one of the biggest signs that there is a problem with your roof. There will be a reason that they have fallen off and this needs investigating as soon as possible. When shingles start to fall off, they have probably already started to curl and crack. If you are at this stage, then you need to call a professional.
