When you ask for a roofing inspection, it’s a great way to assess its current condition. Your roofer may make some recommendations about repairs which need completing or even potential issues to keep an eye on. However, every roof has a lifespan. Here are some of the key signs you may need to replace your roof.

Roof repair guides - key signs your roofing may need fully replacingCost of Repairs

One of the first signs that a new roof may be the best solution for you is if you’re spending a lot of money on regular repairs. For example, it may be that the materials on your roofing are old and have come to the end of their natural life span. This could result in constant problems with your tiling, requiring ongoing repairs and replacements. In these cases, it’s going to be difficult to resolve the issues which keep recurring, so a full roof replacement should be considered.


Whether you’re a home or business, a leaky roof is never a good sign. If you’re experiencing leaks within your property, don’t ignore it. A professional roofer can identify the source of the issue. Perhaps some simple repairs can be carried out to resolve the problem. However, you may also find you keep having leaks if they’re being caused by deterioration within your roofing. Upgrading your roof may be the best option because leaks could cause a lot of damage within your property, so they’re not something you want to occur time and time again.

Issues in Your Rafters

While a roofer will always inspect the outside of your roof, they’ll also take a look in your loft or attic area too if necessary. Signs that you have issues with your existing roofing could be spotted within the rafters. This includes damp or rotting wood, water damage marks or mould. While damage to your roof may have left an entrance point for moisture, if it’s a widespread problem which has been left unaddressed, or your roof is no longer watertight, you may want to think about a replacement.

Structural Damage

If you ever see light coming through into your loft space, call a roofing contractor immediately to come and assess the structure of your roof. Pitched roofing lasts a long time, but some older roofs and poor quality flat roofs may have developed structural issues. Another sign to look out for on your flat roof is sagging and guttering which no longer looks straight or supported. Your roof’s drainage may also be affected. If your roofing is no longer structurally sound, it could put you and your property at risk. A contractor can explain more about the solutions available, and this may include a roofing upgrade.
