Metal Roof Sealant Recommendations


Question


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


Answer


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.

    Best way to get side seams front and back to close back after coming apart after top fell while moving. Seller didn’t tell me it had leaked for years. Have the reccomended sealing tape, but need seams closed good.

      Hello Lynda,

      Thank you for your patience while I reached out to the expert, here is the reply:

      The only thing you can do is try really long screws to drive the seams in. There should have been screws holding it in before and you can remove those and install longer ones in the same area or make new holes around the existing ones. If you are careful and drive the screws straight along the wall edge and don’t angle them you can use 3 1/2″ screws to try to get a better grab on more supports. If those still aren’t grabbing strong enough then the framing supports are too rotted and will need replaced, if it is possible to replace. It depends on how your walls are made but sometimes the whole wall needs replaced and others can have panels taken out to replace the structure. I would not recommend using any sort of adhesive as they will not typically hold up after travel. Screws into the framing is the best option.

    Does anyone know if i can get a power awning put on my 2009 forest river lexington. It has a curved angle at the top of the RV and I can’t seem to find anyone who carries this power awning. Any help would be greatly appreciated.

      If it wasn’t powered before it isn’t easy to get powered ones as you would have to drill through the wall and run wires inside to another power source, sometimes this involves going through ceiling and wall panels. Sometimes it can be easy to. If you did already have a power awning the replacement is easy. You should be able to take out the awning and look at the identification tag to find out who makes it. Usually it is on the tube, arms or even the fabric. You can also call the manufacture with the VIN to find out as well. The only company I was able to find that makes the curved arms was Dometic. They have a chart to find out which system you have but did not mention if it was powered or not. Some of these arms are still available online so it might be worth contacting Dometic directly and see if they have what you are looking for. I will share the link with the arm catalog below.

    RV Ladders. I received the schematic diagram for our camper from KZ. The diagram shows the backing on the back wall, however for the roof their is no cross member. What’s the proper way to attach? Roof decking is 3/8 plywood.

      Hello Thomas,

      Thank you for contacting us, here is the experts reply:

      It will just sit on the roof, there is no extra support on the roof for the ladder. The roof is strong enough to support it without extra wood. It just needs to be screwed into place when resting into position with 1″ screws.

      I personally don’t have any experience with that product but I have heard many good things about it. It does come with a lifetime warranty so as long as they uphold that it sounds like a good investment. I would look up reviews and see what others have said but as I mentioned I have heard nothing but good things about it.

      Eternabond is a great product and works well on metal roofs. It can be used to seal around existing components or when installing new ones. This can be found online and at local hardware stores as well. It is very strong and hard to get off so make sure you are using it over something you want to stay for a long time.

      Hello Keith,

      You will need to use a nut and bolt most likely to hold it in place. Typically they use machine rivets when making the steps and you would need a special tool and rivet to make it original again. Depending on what style of steps you have and who makes them they might have something else that can be used but the ones I have seen can typically only be fixed with a nut and bolt. Use a nylon nut so it locks into place without much tension.

      The two 6v batteries will have to be connected in series. I can share a diagram that shows how to do this but you will need to connect the negative from battery 1 to the positive of battery 2. The negative from the RV connects to the negative on battery 2 and the positive from the RV connects to the positive from battery 1. It sounds confusing but the diagram should help. The chassis battery will be connected in parallel. This means all negatives together and all positives together. The colors for both of these wires can be different on all RV’s but typically red is positive and black is negative but sometimes black can be positive and if there are white wires these can be negative. The only way to know for sure is to trace the wires and see what they lead to.
