How to Seal a Rusty Metal Roof on a Trailer

Metal roofs are notoriously leaky due to the holes that are created for roof anchor bolts. The anchor bolts drive through the metal and into beams of the roof's structure. During installation of the roof, acrylic or silicone caulking is applied around bolts to prevent leakage. Over time, the sun dries and cracks the caulking, leading to leaks. If you have a rusty metal roof on your trailer that leaks, this can be remedied with the installation of a rubber sealant o-ring or reapplication of caulking.

1. • 1

     Brush away loose debris from the surface of the roof.

   • 2

     Tighten any loose roof fasteners with the socket wrench.

   • 3

     Slip a rubber o-ring around the fastener and press it down to the base of the fastener. If you opt for caulking, squeeze a bead of caulk around the base of the fastener. Ensure the bead is continuous and completely fills the area around the base of the bolt.
