When should you replace your roof?

It is a question we get every so often, and typically when there is a problem. It usually comes with a grimace as homeowners realise they have to fork out lots of money to fix something that if caught earlier could have been easier and cheaper to fix or they could have been more prepared. So this month we decided to take a look at the top things to look out for when it comes to roof problems so that you are not caught unaware. What are the warning signs that tell you your roof may need to be replaced?

The age of your roof

Typically, asphalt shingle roofs have a lifespan of 20 to 30 years. Anything approaching that and you need to keep a close eye on it and start putting together a roof fund as it will need to be replaced sooner rather than later. Even if it looks good from the ground, there could be problems that you can’t spot unless you get up there and do a thorough check.

The shingles are doing strange things

By that we mean that they can be curling. What does that look like? There are two ways in which they can do this: clawing, where the edges stay flat and the middle rises, or cupping, where the edges curl upwards while the middle stays flat. Either way, this is a big sign of wear and tear and could let water through. Depending on the extent of the problem you are likely to need to replace them within one to five years.

Cracked and missing shingles

You probably don’t need us to tell you that neither of those is a good sign. While you can replace either of those where there are a few isolated tiles that are affected, you need to be prepared for the fact that you will not be able to match the colour as the old ones will have weathered over time. In addition, there have been plenty of changes over time to manufacturing, style, and colour so finding something close to the original could be tricky.

If the cracking is more extensive over any section of the roof then you should consider a full replacement. Cracking is the result of wind damage and things will only get worse if your problem is already more widespread.

You can see daylight

Another one that doesn’t need an expert diagnosis. If you can see daylight through your roof, then water can also get in. And you clearly need to replace it to avoid the problem getting worse and more complicated. To check for this turn off all the lights in your attic or loft and have a good look up and across the full extent of the roof looking for any signs of light coming through.

A sagging roof

This one requires immediate intervention. A sagging roof is the result of a structural problem and while we don’t wish to alarm you, it’s something that you need to call the experts in for a full assessment as soon as possible. Unless it is widespread it is unlikely to come down on you, but it should not be left unchecked.
