5 Signs That You May Need a New Roof

Finished Result

1. Leaks, water damage and sagging

Watermarks and stains on your walls, ceiling and roof are tell-tale signs that water has seeped in through a crack or hole in your roof. Dark areas or trails mean that mould has already formed on the affected areas, and that these structures could be rotting.

Roofing leaks and water damage can also be spotted on floors as water patches. Dry patches indicate old stains and leaks, while fresh water leaks indicate new damage. Sagging means that the structure of your roof has caved in and gave way, which could be due to long-term exposure to water, weakening the area.

2. Light pollution 

If you can spot light coming in to your attic from your roof, then there’s a chance that you have a crack or hole in your roof – and that will require immediate attention. Even just small rays of light could be a sign of a bigger problem. Once you notice it, make sure to check it right away and seek the help of a professional roofing company.

The best time of the day to go up on your roof is around sunset, as light will still be coming in, but your loft interior will be dark enough for you to see the rays of light.

3. Mould, moss growth and rotting underlay 

Water and moisture is also another common sign that you may need a new roof. If your roof has been exposed to frequent and consistent moisture and cold, mould and moss can grow and cause damage to the structure of your roof. When this situation goes unnoticed and untreated for extended periods, the underlay of the roof will rot and, in turn, weaken the foundation of your roofing.

4. Damaged flashing around chimneys and vents

Flashing is used for chimneys, vents and other structures that protrude from your roof, and is designed to divert water away from the structures to prevent leaks and damage. Flashing is usually made up of galvanised steel or aluminium. If your flashing is already damaged, it may have been because the caulking under the flashing has already dried out, or because the material has simply deteriorated due to oxidation or the weather. With your flashing damaged, water will be able to seep in, causing leaks and surrounding materials to weaken.

5. Age of the roof

There is no hard number as to what age is best to replace your roof, as some materials last longer than others, some installation procedures are better than others, and some homeowners are better at maintaining their roofs than others. However, just like anything else in life, age weakens materials, so if your house is old, it will be more likely for your roof will need a replacement.
