Our Roof leak on our Allegro Motor Home

Just wanted to ask if anyone has tried a do it yourself project of stopping your roof from leaking on an Allegro motor home?

We made a big mistake letting someone kool seal our top, did not know they pressure washed it first but now have a big problem where the elastic coating has leaks in it. We have it parked under our barn but now are unable to use it until we can do the necessary repairs.

We would like to make the necessary repairs, as we miss not being able to use our RV. We learned a lesson, trying to help someone out but has cost us a great deal of heartache and probably a large amount of money to get our motor home back up and running for us to enjoy.

Thanks so much for any and all information.

  • Most sealants, roof products are not "RV brand specific". I doubt Allegro would have anything for you but advice. Here is one option.

    Roof Sealant

    There are many others. Just do a qoogle search on RV roof sealant.
  • Thanks for the reply.

    When we first discovered the leak our home was sitting with the front lower than the back. I noticed what looked like the windshield leaking on the inside to which after checking it was coming in running to the front and down the windshield. It appears to have its own path to do this when our home was lower in the front. We have had it under our barn now for some time, it is all dry with no mold issues or any damage except a few water spots on the ceiling next to the trim nearest the side of the front door on the passenger side and one on the inside of a cabinet door near the front door. We parked it inside as soon as we discovered the leaking.

    We have not used it now for about two years and miss out by this leak. I wondered if there is a skin or some type of something we could buy from Allegro to rework the whole top and coat it with new elastic coating.

    Thanks.
  • Welcome to the forum. If done properly, coating the roof will extend its life.
    If you have holes you can see, Eternabond is your best bet.
    Dicor self leveling caulk is another option.
    Can you give us a little more info about your leaks, maybe someone has a better answer.
  • If you posted more information regarding your motorhome, the type of roof material, it would be more helpful.

    Kool Seal is a product that was targeted for the mobile home industry for use on all metal roofs. It was never designed for the RV industry. You may be in a situation where complete removal of your old roof will be necessary.
