What to Do When Your Metal Roof Squeaks or Expands
Metal roofing is one of the most durable and long-lasting roofing options available, but like all building materials, it has its quirks. Homeowners sometimes notice sounds like squeaks, pops, or creaks coming from their roof, especially during hot summer afternoons or cooler nights. While these noises can be surprising, they are usually not a cause for alarm. Instead, they are a natural result of the way metal reacts to changes in temperature.
In this post, we will explain why metal roofs expand and contract, why they sometimes squeak, and what you can do about it.
Why Does a Metal Roof Expand and Contract?
Metal roofing panels are installed with fasteners and trims that hold them securely in place. However, metal naturally expands in the heat and contracts in cooler temperatures. In Georgia’s climate, with hot sunny days followed by cooler evenings, this cycle happens every single day. Expansion occurs when sunlight heats the panels, causing them to slightly lengthen. Contraction happens at night or on cooler days when the panels return to their normal size.
This movement is normal, but when panels rub against each other, fasteners, or the underlying decking, you may hear noises that sound like squeaks or pops.
Common Reasons Metal Roofs Make Noise
One common reason is tight fasteners or improper installation. If screws or fasteners are overtightened, the panels may not have enough room to move naturally, which creates friction and noise. Another factor is panel overlap. Where one panel overlaps another, thermal expansion can cause rubbing or slipping that produces squeaks. Large swings in temperature between day and night can exaggerate the expansion and contraction cycle. Finally, the age of the roof also plays a role, since some fasteners can loosen or rubber washers can wear out over time, which increases the chance of noise.
What You Can Do About a Squeaky Metal Roof
While these sounds are usually harmless, there are steps you can take to minimize them. Scheduling a roof inspection is a good start. A professional roofing supplier or contractor can check whether the panels are properly secured and if fasteners need adjusting or replacing. Checking fasteners and washers is also important. Fasteners with worn washers should be replaced. This not only reduces noise but also helps prevent leaks.
Using proper underlayment is another solution, since a high-quality underlayment helps absorb some of the sound and creates a better surface for panels to expand and contract quietly. If you are installing a new roof, make sure the contractor leaves proper spacing for thermal movement. Standing seam panels, for example, are designed with clips that allow controlled movement. Lastly, do not ignore excessive noise. Occasional squeaks are normal, but loud or frequent noises could point to installation issues that should be addressed before they cause long-term problems.
When to Call a Professional
If your roof is under warranty, or if you suspect installation errors, it is always best to contact a professional rather than attempting repairs yourself. Improper handling can void warranties or cause leaks.
