Postponing a roof replacement even for a few months can be a disaster. If a storm hits and finds your roof in a poor state, the amount of damage caused inside and outside your building could be immense. However, a common problem is that many building owners can't even tell when it's time to replace their roofing.
Many people are only guided by the projected lifespan of their roofing material. However, many people have had to replace their roofs long before or long after this. How can you know when it's time?
A Large Section of the Roof is Damaged
When a small section of the roof is damaged, this can be replaced without having to worry about the rest of the roof. However, an extreme weather event can result in serious damage to a large section of the roof. While it may seem economical to only replace the damaged sections, this may not make sense later. For starters, it may be harder to match the old roof sections with the new ones. Secondly, this can create additional challenges when the older roof sections start to deteriorate due to age.
If you're dealing with leaks in your roof on a regular basis, it's possible that it's time to get rid of the whole thing and put in a new roof. Frequent leaks are often a sign that the entire roof is deteriorating. Patching leaks may work in the short-term, however, a single leak can cause serious damage before you've even noticed it.
Parts of the Roof Are Sagging
Roofing can sag for a number of reasons and none of these reasons is good. A roof can start to sag if the underlying structure is weakened or damaged. This means that the structure is no longer able to support the weight of the roof. The roof can also start to sag when it has absorbed too much water. This can happen if the moisture barriers under the roofing material are compromised. In such cases, the roofing material and even the underlying structure may need to be replaced.
Poor Energy Performance
With energy prices going up, you'll need every part of your home to be as energy efficient as possible. The roof plays an important in your home's energy efficiency. If you feel your old roof is no longer energy efficient it may be time to call a commercial roofing contractor and start discussing replacement options.
