What are the 4 Disadvantages of Fixing an Old Roof?

Jan 28


Is your flat roof membrane old and leaking? According to experts in flat roofing, there are times when repairing a flat roof membrane is not an option. Our roofing experts outline four of the most disadvantageous aspects of fixing a flat roof membrane rather than replacing it.

1. The Repair might not hold

It can take too long to fix an old roof because the material is weak and old. If you are laying new roof shingles on an older deck, it is possible that the foundation will not be strong enough to keep them secure. The leak might be fixed immediately, but substantial rains could cause it to return.

2. You might also have issues with other parts of the roof

An old roof can have weak components, so there is a high chance another roofing problem will arise shortly after you've fixed the leak. Experts in residential roofing say this will only lead to more repairs in the future. It's better to replace the entire roof system.

3. This Fix might not even work!

Sometimes, a roof that is deteriorating can have multiple problems. It may be challenging to identify the source of the leak. Some people make incorrect assumptions and fix one spot on the roof, only to later discover that another is problematic.

4. You will need to cover repairs

Warranty coverage for old roofs is rare, if any, available. Roofing repairs will almost always be completed in full. A complete roof replacement will likely mean that roof repairs for existing issues will be covered under a product warranty. Local roofers can help you replace your roof.


Fixing an old roof can have several disadvantages. Firstly, it can be quite costly as the materials and labor required to fix an old roof can be expensive. Additionally, the older the roof, the more likely it is that it will require extensive repairs, which can add to the overall cost. Secondly, fixing an old roof can be time-consuming, as it may require several days or even weeks to complete the repairs, depending on the extent of the damage. 


This can be a significant inconvenience for homeowners, as they may need to temporarily relocate while the repairs are being made. Finally, fixing an old roof does not guarantee that it will last for a long time, as the age of the roof may mean that it is more prone to future damage or leaks. In these cases, it may be more cost-effective and efficient to simply replace the entire roof.

In conclusion, fixing an old roof can come with several disadvantages. The cost of repairs can be high, especially if the roof is in poor condition. Additionally, the process can be time-consuming, which can cause disruptions to your daily routine. Furthermore, older roofing materials may not be as energy-efficient as newer options, resulting in higher energy bills. While it may be tempting to put off repairs, it's important to address any issues with an old roof as soon as possible to avoid further damage and costly repairs in the future.
