Because of their durability and longevity, metal roofs are slowly getting more popular. Shingle roofs are still the most common in Seattle, but because metal roofs are on an uptrend we've researched and applied the best methods for metal roof cleaning. Now, we want to share our practices and what we've learned.
It's true that although metal roofs are more durable than shingle roofs, they also require regular maintenance. Just because your roof is metal and might be able to hold up against storms better than a shingle roof, that doesn't mean they won't be damaged by Seattle's unique climate. If you've lived in Seattle long enough, you'll know our climate here is more damp and humid compared to other American cities. That's why moss loves it here. And, although metal roofs are more resistant to moss growth than shingle roofs, moss still loves metal roofs, too.
How does moss damage metal roofs in Seattle?
Moss is excellent at absorbing and retaining water. That means, even though metal roofs are typically stronger than shingle ones, moss build up, especially when the moss has grown out of control and retains water, adds a lot of extra weight to the structural integrity of your roof which can undermine the whole point of having a stronger roofing material when structural deterioration starts to occur. Also, because moss is constantly retaining the moisture of Seattle's climate, that means water is constantly trapped against the metal which causes corrosion and discoloration over time, which can result in rust and leaks if left untreated.
The best way to clean metal roofs in Seattle
We specialize in cleaning all types of metal roofs, including painted metal roofs, stone-coated metal roofs, corrugated metal roofs, aluminum roofing, steel roofing, tin roofing, and even copper and zinc roofing. Each type of roofing material requires slightly different practices, so we won't go into each one here but we'll give a general overview of our metal roof cleaning process for the most common types which are painted and corrugated metal roofs.
We use soft bristle brushes and non-abrasive pads for cleaning metal roofs where possible, and pressure washing machines where needed. While it's not recommended to pressure wash shingle roofs, pressure washing certain metal roofs is fine so long as it's done by an expert with the correct nozzles and PSI (pound per square inch). We've seen the best results with custom-tailored solutions to each roof, taking into account factors such as roofing material and the amount of moss, lichen, and debris that needs to be cleaned. Starting with a soft brush to remove moss and debris, we use detergents and pressure washing to give a final finish that will leave your metal roof sparkly clean like new again.
