Signs Of Metal Roof Repair Vs. Replacement

A metal roof is an investment that will last for several decades. But that doesn't mean it won't need maintenance or repairs along the way. But how do you know when a problem can be solved by repairs and when the roof needs a full replacement? Here are common signs that indicate a repair will fix the problem and signs that might indicate a full replacement is needed.


Small leaks

A metal roof is a durable and long-lasting roofing system but that doesn't mean that it's impervious to potential problems. Small isolated leaks are often easily repairable. Sometimes the problem is related to small perforations by improperly fixed nails that can be replaced. Damaged flashing or open laps might also be repairable problems responsible for small leaks.


When the coating of a metal roof becomes damaged, it can lead to discoloration on the surface and that can eventually lead to the more corrosive problem of rust. Fortunately, this is easily repairable by touching up the coating or replacing a panel, especially if you catch the problem early.

Poor Installation

In some cases, a few panels may have been improperly installed. When the problem is isolated to one or a few problem areas on the entirety of the metal roof, it can often be easily repaired. One sign of poor installation is a wrinkling panel. This is caused by improper placement that didn't leave room for expansion and contraction of the metal. Replacing the panel in the correct alignment can often fix the problem.



The number one factor in determining if a problem is repairable or if replacement is needed is the age of the roof. If your roof has reached the end of its lifespan, fixing one problem may not be enough because others may follow soon after. Find out when your roof was installed and then check with the manufacturer of your roofing system to determine the average lifespan of your specific roof.

Widespread Damage

Another cause for roof replacement is widespread damage. This may be due to storm damage such as projectiles caused by high winds or punctures from branches or trees. Additionally, if there is widespread damage to the coating on your panels and rust has spread over the majority of the roof, this might also be a cause for replacement.

Constant Problems

Another reason for replacement is if you continue to experience constant problems with the roof. You may repair one problem only to have another crop up shortly after and then another. A problematic roof is often cheaper to replace than to continue to constantly repair.
