Shipping Details

When there’s a nagging roof leak that others can’t fix, or when you don’t want to take your chances, use Through the Roof!® Its unique co-polymer rubber formula creates a permanent, invisible seal, even when applied in the middle of a rain storm. (It works great on dry surfaces, too). Through the Roof! will stick to almost any roofing surface – metal, plastic, asphalt, wood, concrete, and more. Plus, it won’t freeze. So go ahead and fix that gutter in a Minnesota winter.

What Customers Are Saying

Customers overwhelmingly praise this roof sealant for exceptional leak-stopping performance, with many reporting sealed gaps, flashing, gutters, and siding lasting five years or more through heavy storms. Reviewers consistently describe it as durable, tough, and versatile across metal roofs, vinyl siding, and vent pipes. Most find it easy to apply and appreciate its paintable finish. However, some report the caulk is extremely thick and difficult to squeeze from the tube, and several note the advertised wet-surface application claim is misleading—the product fails to adhere during rain or wet conditions. Despite these application concerns, the vast majority consider it a top-tier solution for urgent roof repairs.

I bought Through the Roof Synthetic Rubber Chalk to repair a leaky gutter seam / slip joint. The water was leaking through the deteriorated rivets and slip joint. The chalk was easy to apply and I now have no leaky gutters!

I recently used this to weatherproof my new tankless water heater in my RV. It sticks well to the fiberglass surface and dries into nice and clear, stretchy solid weatherproof bead.
