Caring For Metal Roof Screws

On metal roofs, the screws that hold the panels in place are made to survive for many years, if not decades. It’s still crucial to have them inspected annually to ensure they aren’t missing, slanted, loose, or crooked, as this can happen as a result of your roof expanding and contracting over time.

What Causes Screws To Back Out Of a Metal Roof?

Screws can back out of a metal roof for several reasons. Let’s take a look at them:

Thermal Expansion

Your roof will expand and contract with seasonal temperature variations. For this reason, before installing the panels, your roofing contractor should make sure there is adequate space between them. The screws keeping the roof in place can come free due to the panels’ altered sizes.


Your metal roof’s screws might come loose as a result of the compression process. For instance, your roof may drop lower than the screws when there is a lot of snow or ice on it, leaving the screws exposed. When the ice and snow melt, the material will typically reposition itself, but the screws can come loose at that moment.

Water Damage

Moisture of any kind seeping under the panels could harm the underlayment and cause the roof’s screws to come loose. This is because damaged underlayment may make screws in the roof framework no longer strong enough to hold it down.

How Often Should You Replace Screws on a Metal Roof?

The lifespan of your metal panels is equal to that of the metal roofing screws. Their lifespans, however, can vary based on the weather conditions your roof has seen and the caliber of the roof installation. It is advised that you look for evidence of wear and strain on the screws during your roof inspection.

How Long Do Metal Roofs Last?

One of the key advantages and the main reasons homeowners select metal roofs is their longevity. Metal roofs can endure for fifty years or longer if they are installed and maintained correctly. The most frequent elements influencing the longevity of metal roofs are listed below.


Your roof’s lifespan may be impacted by the type of fastener you use and the caliber of the installation. For instance, because standing seam metal roofs permit the panels to expand and contract in response to temperature changes, they often survive longer than screw-down panel roofs. If the roof was placed improperly by the contractor, repairs and even a replacement will also be necessary sooner.

Paint Finish

Your roof will look better and be more protected from the weather with a paint finish. Make sure to have any paint chips or coating damage fixed as soon as you see them since they could shorten the life of your roof and result in other kinds of damage to your house.

Local Weather Condition

The lifespan of your roof may also be impacted by weather conditions. Even though metal roofs are strong and made to resist the elements, severe weather can still cause damage. For instance, metal panels are susceptible to dents from hail or ice, and fluctuations in temperature can cause the metal to expand and contract, which, if your roof isn’t prepared for, might result in further issues.
