Is Your House Covered if Mt. Rainier Erupts? -Pt 2 Ash

April 28, 20261 min read

Washington homeowners — do you actually know if your house is covered if Mount Rainier erupts?

Most people think volcanic ash is just dust you can wash off…

But it can actually collapse a roof.

When Mount St. Helens erupted in 1980, areas nearly 80 miles away ended up covered in ash.

And when ash gets wet, it becomes incredibly heavy.

It can weigh 10 to 20 pounds per square foot sitting on a roof.

That kind of weight can cause serious structural damage.

The surprising part is that many homeowners policies actually include coverage for volcanic ash.

But the wording in the policy matters.

When Mount St. Helens erupted, ash covered cars, rooftops, and entire neighborhoods across Washington.

That’s exactly the kind of fine print I help families catch before it becomes a very expensive surprise.
