Weather can affect how well your metal roof holds up over time. Even though metal roofs are tough, they still have to deal with the weather. Different kinds of weather can cause problems for metal roofs. For example, really hot or really cold temperatures can make metal expand and contract, which can lead to damage like warping or cracking.

In this article, we’ll explore how different weather conditions can affect the performance and longevity of your metal roof. Remember that if you install your metal roof correctly, keep up with maintenance, and use good materials, you can help protect it from the weather. And metal roof experts like can be your go-to solution provider.

Impact of snow and ice on metal roof

When snow and ice come together, they create big problems. They hide dangers and make it hard to move around safely. Ice can form on important things like pipes and harnesses, making them even riskier. Even retractable lifelines can freeze up and stop working.

When water freezes, it expands and can cause damage, just like a water bottle bursting in the freezer. Metal, including metal roofs, can also be damaged, especially if there’s no way for the water to escape.

So, if things freeze up or get covered in snow, don’t use heat guns to thaw them – it can make things worse. Instead, use gentler methods like towels or special tools. And always make sure safety systems are well-made to avoid adding to the risks.

Impact of windy weather on metal roof

Strong winds, whether from a big storm or just a windy day, can ruin your metal roof. Roofs are made to handle wind in your area, so it’s rare for sheets to fly off, but it can happen in really extreme cases.

What’s more common is that sheets and flashings can gradually move, even if they were installed properly. This movement can create weak spots in your metal roof, letting water in and causing damage over time. But the good news is that metal roofs usually have fewer seams than tiled roofs, so there’s less chance of this happening.

Another thing you should be concerned about is trees rubbing against your roof or gutters when it’s windy. This rubbing can damage the roof coating, leading to corrosion. To prevent this, make sure trees aren’t touching your roof. Keep an eye on tree growth and trim them back if needed.

Impact of Heavy rain and water on metal roof

Heavy rain can mess up your metal roof, almost as much as big disasters like floods and cyclones. When it pours, water can cause lots of problems that weaken the metal roof’s structure. The most obvious issue is leaks, which happen when water builds up and sneaks into your roof.

Leaky metal roofs often lead to mold or water dripping from your ceiling. In serious cases, leaks can make wood rot or mess with the foundation of your house and roof. So, when leaks happen, it’s important to find where they’re coming from and fix any holes or cracks to prevent more leaks. Plus, don’t forget to keep your gutters and drains clean to stop water from backing up.

If a downpipe gets blocked and water can’t go anywhere, it’s bad news. Your home could end up flooded, and water might even seep under your house or into your roof. So, make sure to clean your gutters regularly and fix any issues to avoid stress and damage later on.

Extreme heat can impact metal roof

Hot weather can also affect your rooftop. In scorching conditions, the roof membranes might stick to equipment or systems in place. Walking on the roof surface can be tough and might even damage the membrane. Using raised walkways can help because they keep you off the roof surface and spread your weight more evenly across it.

Just like with cold weather, it’s important to think about heat when designing the system. Temperature changes can lead to thermal expansion, which might loosen or tighten systems. This could end up damaging or making the protection measures ineffective. So, it’s essential to consider these factors before setting everything up.

Hail damage

Hailstorms are happening more often these days. Depending on how big, heavy, and dense the hailstones are, they can cause a bunch of problems. When the hail is small, it might just mess up your gutters and metal roof a bit. But if the hail gets bigger, it can damage your roof – knocking things out of place, cracking, or even breaking them.

And it’s not just the roof that gets hit. The debris from damaged roof coverings can block your gutters and cause water to build up. If your house has a chimney, skylight, or metal vents, they can get damaged too. Sometimes, really big hailstones can even punch holes in older roofs, letting water inside.

So, after a hailstorm, it’s a good idea to have someone who knows about roofs and check yours. They can see how bad the damage is and figure out if it can be fixed or if you need a new roof altogether. It’s better to take care of any problems early on to keep your home safe.

Impact of weather on metal roofs in coastal area

Living near the coast in Canada and the USA means facing the challenge of corrosion. Metal roofs that reside by the ocean are at risk of rust and corrosion due to salty sea air and humidity. The closer you are to the ocean, the faster these issues occur.

However, you don’t have to move inland to protect your roof. The trick is to use the right products. Metal roofing has gotten better, and there are special products with the latest technologies.
