We have a video demonstrating aluminum boat repair: Fixing Leaking Rivets in an Aluminum Boat. After the area around the leaky rivets is cleaned and well scuffed, heat the area with a propane torch to drive off moisture and warm the metal.
Their roofs tend to be built of thin spars and thin sheet materials due to the need to save weight.
The stresses in any of these lightweight constructions may cause seams to spring away from their carrier ribs.
Check gutter joints, seam rivets and roof-light enclosures on caravan and boat roofs for signs of corrosion and distortion.

We use Rubba-Roof on a regular basis for school projects in Wales and have always been more than satisfied with the service received and the finished result. We find that Rubba-Roof offers us an effective and economical solution for the long term maintenance of flat roofs within the school estate. I was quite surprised to find that every aluminum boat owner I talked to said they had some sort of leak. The heat initially thins the epoxy, allowing it to seep into the smallest crevice, and then speeds the gel time. Another common site of leaks is along the gutter channels at the edges of the roofs of vans and boats; the flexion through the side panels travels vertically but is then transferred into a horizontal vector causing a reflective stress at the joint. To reduce the possibility of destruction or distortion, I tilted the boat and only filled one end at a time since filling the boat up entirely might have done more damage to the seams.


Heat  the repair area with a propane torch (a heat gun will work) up to 180–220°F to dry out the repair area. The wheelhouse coverings on narrow boats, barges and other craft may be of GRP, metal or timber. Complete heating and filling each rivet or seam section before moving on to the next to avoid too much heat loss.
