What is waterproof siding?


While vinyl and aluminum siding are often called “waterproof,” understand that even they require expert installation to truly protect your home. Most siding materials are waterproof, withstanding harsh conditions for years. However, even minor leaks can cause major water damage behind any siding. Let’s explore popular siding options and their water resistance: fiber cement, steel, vinyl, aluminum, and cedar.

Proper installation is also crucial to ensure complete water protection.
