Hey there! As a side flashing supplier, I've been getting a lot of questions lately about how long side flashing lasts in different climates. So, I thought I'd put together this blog post to share some insights and help you understand what to expect.
First off, let's talk about what side flashing is. Side flashing is a crucial component in roofing systems. It's used to prevent water from seeping into the joints between the roof and vertical surfaces like walls or chimneys. You can check out our Side Flashing for more details on the types and features.
Now, let's dive into how different climates can affect the lifespan of side flashing.
Hot and Dry Climates
In hot and dry climates, side flashing is exposed to intense sunlight and high temperatures. The UV rays from the sun can cause the material of the side flashing to degrade over time. For example, if it's made of a plastic or resin material, the UV rays can make it brittle and prone to cracking.
The lack of moisture in the air can also be a problem. Without regular moisture to keep the material flexible, it can become stiff and break easily. On average, in a hot and dry climate, side flashing might last anywhere from 10 to 15 years. However, this can vary depending on the quality of the material and how well it's installed.
Humid and Tropical Climates
Humid and tropical climates bring a different set of challenges. The high levels of humidity can lead to the growth of mold and mildew on the side flashing. This not only looks bad but can also weaken the material.
Heavy rainfall in these areas can also put a lot of stress on the side flashing. If the water isn't properly diverted, it can seep behind the flashing and cause water damage to the underlying structure. In a humid and tropical climate, side flashing may last around 15 to 20 years. But again, proper installation and maintenance are key to achieving this lifespan.
Cold and Snowy Climates
In cold and snowy climates, side flashing has to deal with freezing temperatures and the weight of snow. When water freezes, it expands, which can put pressure on the side flashing and cause it to crack or separate from the surface.
Snow can also act as an insulator, trapping moisture against the side flashing. This can lead to corrosion, especially if the flashing is made of metal. In a cold and snowy climate, side flashing typically lasts about 12 to 18 years.
Mild and Temperate Climates
Mild and temperate climates are generally more forgiving for side flashing. The moderate temperatures and relatively stable weather conditions mean that the side flashing is exposed to less stress. As a result, it can last longer, usually around 20 to 25 years.
But even in these mild climates, it's important to keep an eye on the side flashing. Regular inspections can help you catch any issues early and prevent them from becoming major problems.
Factors That Affect Lifespan
Apart from the climate, there are other factors that can affect the lifespan of side flashing. The quality of the material is a big one. Higher-quality materials are generally more durable and can withstand the elements better.
Installation also plays a crucial role. If the side flashing isn't installed correctly, it can lead to leaks and premature failure. Make sure to hire a professional installer who has experience with side flashing.
Maintenance is another important factor. Regularly cleaning the side flashing and checking for any signs of damage can help extend its lifespan.
