Signs that indicate that your roof should be repaired rather than replaced

The roof of the house is the essential part of the house. It protects your family from extreme weather conditions. Therefore, it is very crucial to inspect your home regularly. The state of your roof will indicate if you need to repair or replace it. Here are some signs that indicate that your roof should be repaired rather than replaced:

A buildup of shingle granules in your gutter

This is a sign that you have an old roof. When the shingles deteriorate, they release their granules into the gutter system. This can cause blockages in the gutters, further damaging your house's foundation. Therefore, it is advisable to replace an old roof before it worsens.

Mould growth on your roof

It is usual for mould to grow on roofs when there is too much moisture. However, continued mould growth indicates that there are leaks in your roof. Therefore, you should take the necessary measures to repair or replace it before getting worse.

You can see the source of the problem.

If your roof is leaking or sagging in one area, it's only a localized issue and not a general problem with the entire roof. If your roofing contractor can quickly pinpoint the problem and confirm that it's not something more serious that needs to be addressed immediately, repairing it could be a good option.

The damage is minor

If only a few shingles have been damaged, it's only a minor problem and not too extensive. In this case, you won't have to replace the entire roofing system because the damage is minimal and localized.

The age of the roof

Roofs have an average life span of 20 to 30 years. If you're within this range, it's only standard for repairs on minor damages. However, suppose your roof has exceeded its life expectancy and has undergone several repairs in the past months or years. In that case, you should consider replacing it with a brand new one because more damages are expected in the future.

Signs that indicate that your roof should be replaced rather than repaired In Montgomery County

It's important to know when necessary to repair your roof versus when you should just replace it. Here are some signs that indicate that it is time to replace your roof:

Ageing Roof

If your roof is over 20 years old, it may be time to consider a replacement. Even if your roof looks solid from the outside and inside, there may be unseen damage that can only be found by hiring a professional roofer to inspect the inside of your roof. Neglecting maintenance or repairs for an aging roof can lead to more costly repairs or replacements. 

Falling Mortar

If you have noticed missing mortar or crumbling shingles outside your home, there is likely hidden damage within your roof. This kind of damage often indicates that a problem with the structure or foundation of your home has been neglected for too long. A professional Montgomery roofing company can help you determine if any repairs need to be made before they can replace the whole thing.

Missing Shingles or Granules

Missing shingles can often be repaired, but if you have several missing shingles in different roof sections, it could be time to replace them. Also, if you notice granules collecting in the gutters, your shingles are wearing down and will likely need to be replaced soon.

Rotting underlay

The underlayment of your roof is critical in preventing water from leaking into your home. If you notice that your underlayment has started to rot, this can be caused by moisture getting trapped between the shingles and the underlayment. Once these materials soften and become saturated with water, they will begin to rot and cause leaks on your roof. If you notice any rotting on your underlayment, it is essential to have your roof replaced as soon as possible.

Missing Flashing, Gutter Guards or Fascia

The area where your roof meets your gutters or your home's foundation must be appropriately sealed with flashing. This is particularly true around dormers and chimneys. If you have noticed flashing missing around these areas or noticed rust stains in these places on your roof, it may be time for you to replace it rather than repair it.

Benefits of roof replacement over a roof repair

You need to know about the benefits of roof replacement over a roof repair. This will help you understand when you should opt for a roof repair and go for a complete replacement. Here are some benefits of roof replacement over a roof repair in Montgomery County:


New roofs usually last for two times as long as repaired ones. If your roof lasts for ten years, its repaired counterpart will wear out in 5 years. This is the main difference between these two options.


A new roof comes with a manufacturer warranty for its materials and installation. On the other hand, companies do not provide any warranty on their repairs. Therefore, if something goes wrong with your repaired roof, you can not get it fixed without additional charges. If something goes wrong with a new one, you can get it fixed without paying anything extra.

Energy Efficiency

Replacing your old roof with a new one will make your home more energy-efficient than before because newer roofs come pre-equipped with energy efficiency features that reduce energy consumption in your house. On the other hand, repairing an old roof does nothing to increase your home's energy efficiency.

Preventing Future Problems

When your roof is repaired, there's no guarantee that it won't begin to experience problems once again in a short amount of time. If you have multiple shingles that are damaged, a new roof can prevent problems from occurring in the future. Over time, if your roof is repaired numerous times, these repairs can add up; investing in a brand new roof right away can save you money in the long run.
