Metal Roof Sealant Recommendations

Ask an RV Expert


My rig has a tin/metal roof and I’m seeing some water deposits inside. I’m noticing some small holes in the tin – what should I seal it with?

Submitted via email


I would recommend the metal roof coating from Dicor. It applies easy, will seal the holes and actually insulate the inside better as well. Check out their Elastomeric Metal RV Roof Coating and give it a try. I hope this helps!

Dicor additionally makes sealants for all roof types, not just metal or tin. They have products to help clean, replace, protect, and repair your RV Roof.

    Our shop has been using rv roof magic for years now. Many reason but the main one is that we never had a customer call us about product issues. For us it is the best rv roof sealant out there and it never needs a primer one coat also. Their site is

    I hit a column and messed up the back corner and have new corner pieces but what is the best way to get the old caulking off? It seams more like a sealant versus caulking.
