The importance of checking your roof regularly

Don’t underestimate the importance of checking your roof regularly for damage. Determining your roof’s condition from how it looks isn’t always easy, and it often requires inspection by an experienced roofer. Regular roof inspections allow you to find any damage early on. This allows you to make the necessary repairs before they become more expensive to fix. Finding damage promptly can save you a lot of money and trouble in the long-term. 

The biggest signs your roof needs replacing 

When it comes to your roof, it’s better to be safe than sorry. If you’ve noticed any problems with your roof, it’s important to best to address them as quickly as possible. Although replacing your roof can be costly and inconvenient, it may be necessary to prevent water coming into your home. Damaged and ageing roofs can also look unsightly and are likely to bring the value of your property down. A new roof is a very worthy investment in many cases. 

Water damage 

Have you noticed water damage in your home? Perhaps you’ve spotted wet patches upstairs? If so, you might assume that you have a case of damp or that water came in from a window during the last downpour. However, the problem may actually be your roof. If your roof is cracked or has a hole, water could be seeping in and causing damage. If you notice signs of water damage in your home, you need to arrange a roof inspection. Call our professional roofers in Grimsby or Louth as soon as possible.

Mould or moss growth 

Moss or algae growth on your roof can be concerning, particularly if you’ve let it grow unchecked for several years. In some cases, their growth could force the tiles to move apart, creating gaps that let in water. If you notice moss in small sections on your roof, you should remove it. Whilst you can do this on your own, many people find it easier to find a roof to do the job for them. Small patches of moss or algae are usually not a problem. However, if the moisture travels underneath the tiles, the components of the roof could become rotted, threatening its structural integrity. This often requires a full roof replacement. 

Loose roof tiles 

How can you tell if your roof needs to be replaced?

Although a few loose roof tiles may not seem like a big deal, ignoring the issue can lead to serious damage occurring to your property. A roof with damaged or missing tiles can become structurally unsound, so it’s important to deal with the problem right away. If there are more than a couple of tiles loose or missing, you may want to consider replacing your roof. At Raven Roofing and Repairs, we can inspect your roof to see whether your tiles are loose. 

Light is coming through your roof 

If you can see daylight coming through the roof tiles in your loft space, that’s a good sign that your roof needs repairing or replacing. Even if the gaps that allow light to enter are small, this could be the start of a bigger problem. Your roof may have cracks or holes in it that need dealing with as promptly as possible. To check if light is coming through your roof, turn the lights out in the upper rooms of your property and look upwards. If there’s any light entering your home, your roof needs assessing to see if repairs or a full replacement is required. 


If your roof is sagging, this is a big sign that replacement may not be too far in the future.  Sagging may result from weakened joists or issues with the layers underneath the exposed roofing. This is often caused by too much weight being placed on the structure (e.g. rainwater, snow, or ice) or due to improper installations. Take a look at your roof and see if it’s following a straight line along the ridge. If it’s sagging in the middle, structural damage may have occurred and there is a risk of the roof collapsing if you don’t take action. 

Your roof is old

Knowing when your roof was installed (as well as what’s made from) can offer insight into how much life it has left. For example, a roof made from asphalt shingles may last up to 25 years, whereas a roof fitted over an remaining sheet of shingles should ideally be replaced after 20. Whilst roofs in the UK are designed to stand the test of time, they don’t last forever. Extreme weather will eventually take a toll on the roof, causing damage that can’t be easily fixed.
