A roof wears out with time, and this wear causes its appeal and performance to dwindle. Although you can repair the roof and restore its performance, there are instances when you need to replace it. For instance, if you have had the roof for several decades, you might need to replace it with a new one. Apart from age, there can be damage to the roof that demands a new roof to be installed. Here are the two common signs that you will soon need roof installation services:

Curling Or Missing Shingles 

When you notice that your roof is missing some shingles or several that are curling, you should consider having the entire roof replaced. Curled shingles are caused by poor attic ventilation, multiple layered roofs, poor shingle installation, and old age. This issue is a sign that your roof has a greater problem. If you have a few curled shingles, the most cost-effective solution is to have them repaired. However, when you have many shingles, replace the roof because it is a sign that it has reached the end of its life. 

When your roof has missing shingles, it can cause the rest of the roof to deteriorate fast. For instance, when you have missing shingles, the gaps allow water to penetrate, which causes interior damage. Additionally, when the roof is leaking, it causes water damage, mold growth, and it may even lead to structural damage to your home. If you only have a few missing shingles, you can replace them, but it is always advisable to replace the entire roof if you have many missing shingles.

Weakened Sheathing

Sheathing refers to the wood that supports the roof. When the decking or sheathing of your house is damaged, it negatively affects the roof's performance. It can be hard to tell when the sheathing has a problem because it's in between the shingles and the attic insulation. The majority of the homeowners only find out that this area has a problem when the entire roof is compromised. Therefore, it is important to regularly inspect the roof to identify any damage that compromises the sheath's performance. When the sheath has a serious problem, it's unable to support the roof, and this can cause the entire roof to collapse. Therefore, the moment the sheath shows signs of damage, you should consider replacing the entire roof. 

When the roof is worn out, it loses its aesthetic value, and its performance reduces. Some damages can be repaired, but you need a new roof installed if your roof gives off any of the two discussed signs.
