The Difference Between Re-roofing and Roof Replacement

A well-designed and built roofing system is the most valuable investment on your home as it safeguards your home and everything in it from the harsh weather elements.

When signs of damage start showing up on your roof, the decision as to whether reroofing or roof replacement is the best option can be a hard nut to crack for most homeowners. However, a trusted roofing company like Red Tag Roofing which specialises in re-roofing will help you solve the equation in no time. 

Despite the fact that most roof-related issues can be resolved through quick fixes, there are times when roof replacement becomes essential particularly when the state of the roof is beyond repair either because it’s old or can’t withstand future storms.

So, should you reroof or replace? Well, let’s delve into understanding the two terms and you’ll know the answer to this question by the time you reach the end.


The process of reroofing is simple and features the installation of a new roof by installing a roof on top of the old one. Generally, re-roofing is less expensive than installing a completely new roof. However, this option is not for everyone. If your house already has two layers of roofing materials, forget about re-roofing. The option also depends on the material used on your roof. For example, and asbestos roof would need to be safely removed and replaced due to the carcinogenic properties of the material.

In addition, re roofing Perth experts advise that this option is only suitable for roofs that are still in good shape with no damage to the framework. Keep in mind that it’s not worthwhile to re-roof small parts of your roof; it’s better to reroof the whole of it. Hence if re-roofing isn’t an option, then you should consider a roof replacement.

Roof Replacement

Roof replacement is common in situations when the roof frame has major problems. This option involves tearing off everything on the existing roof all the way to the frame and making any repairs before installing a new roof. Unlike re-roofing, roof replacement can be done regardless of how many layers are already on the roof. Hence, it’s a preferred option when reroofing isn’t possible.

When your roof isn’t in the best condition, consider which option will be best for you. And when you need a re roofing Perth or roof replacement Perth specialist, be sure to choose Red Tag Roofing, the go-to roofing company that specialises in re-roofing, particularly steel roofing.
