How long your roof will last is dependent on a number of factors including the roofing material, the climate and rainfall levels. An aging roof that's not addressed can cause significant and costly problems, such as dampness in your home and mould growth. A damaged roof can also make your home less energy-efficient, as there will be an increase in the movement of air in and out of your home. Understanding the warning signs that your roof may need replacing can help prevent damage to your home and allow you to plan for a complete replacement rather than having to navigate emergency roof work. Read on to learn about two common signs your roof may need replacing.

Your Roof Has More Than One Leak

Common causes of a roof leak include a slipped tile and a blockage in the guttering. It's not unreasonable to expect a leak every now and then, particularly if you live in an area that experiences high winds. However, if your roof is developing leaks in several areas, it's a sign that your roof is worn and coming to the end of its lifespan. A leaking roof can cause rot to develop in the timber trusses, so it should be addressed as soon as possible.

Areas Of Your Roof Are Sagging

A visual inspection of your roof from the ground will allow you to spot any areas that look like they are sagging, and it's a good idea to check for this problem at least once a year. Rotten roof rafters will cause your roof to sag, and the roof rafters can rot due to a build-up of moisture in the roof space. This can occur when fine cracks have developed in your tiles or asphalt and allowed small amounts of moisture to seep into the roof space without causing noticeable leaks. When your roof rafters are no longer strong enough to support the roof tiles, your roof could cave in at the damaged area.

Having your roof replaced may seem like a daunting task, but it can be less inconvenient than multiple roof repairs and dealing with internal dampness and damage to the structure of your home caused by longstanding water ingress. If you have concerns about the condition of your roof you can have it inspected and your roofer will give you a report stating what, if any, damage is present and the steps required to tackle the problem.
