Antigua 215sb Roof Repair...updated

Today I began the removal of bad patching on this 2005 Hybrid we recently acquired. The skylight and vent in the bathroom (sound familiar) was badly patched and on our first camping trip we had torrential downpours that flooded the bathroom. So since then I've been researching here and other TT forums for examples, youtube, etc.

I believe this can be partially reroofed. There is solid full EPDM adhesion from the front edge for about 14 feet - full width, then I have loose but intact EPDM until the Skylight openings and rotted wood around that area...see pics.

I could get away with a 6' by 6' EPDM "patch" once the structure is replaced but I think going full width with one seam across the roof would be better. Appreciate the DIY pros opinion on this. But wait theres more.

The roof deck is a Luan sandwich with polystyrene foam and in this back area over the rear bunks and bathroom wall I dont see any beams or structure. I imagine the Luan/foam deck can span the 4.5 feet and use the bathroom wall top as a bearing, but where are the beams? I cant see any in that last 6 feet of exposed deck wood, Luan foam assembly. Should I replace this deck structure with the same Luan/Foam board? I cant find this material at Home Depot/Lowes. Forget Camping World, those guys are trying to sell me a 40 foot roll of EPDM for a full reroof for $1400+ today.

Again, thanks in advance for any input.

  • So I measured and fabricated (3) 1.5 inch aluminum angles to fit those spans. Then I bolted the double angle together to stiffen any chance for deflection. Here they are pre-installation:

  • So the deck support changed a bit. There is a board to board joint that pronounces the sag approx. 6 inches inside the kitchen/bath wall which I used for a slot to house the main double aluminum angle.
    Where that break is, that required an angle across the door header to bridge the support like this:

    Great job on the 3D picture. Although mine is a Jayco it is the same year and same type of roof. Never had to fix anything on the roof but had to fix a spot on the floor from a leaking tub drain that we did not notice until damage had been done. It is a pain in the butt to work on. But that is the trade off to keep these things light weight. Although I have no roof leaks mine is getting recoated this spring with this stuff.
    Liquid roof

    Good luck.
  • Owned one of these brand new.

    The whole thing really is just a luan/fiberglass/Styrofoam sandwich with AL studs at semi regular intervals, the best of which is around the a/c unit on the roof.

    I was told NOT to walk on the roof without putting down a sheet of plywood to distribute the weight or I might find myself with a hole in it.

    Walk cautiously!

    edit - seen the picture! Sorry I'm at a lost for that one.
  • So after consulting and studying the conditions, my plan is to leave the Foam intact and shore it up. The Luan/Foam/Masonite sandwich board is the heart of the structure and other than the top luan layer being damaged and /or gone, I can replace that layer on top of the intact foam, secure it and roof over the back 6 feet. I will remove the trim and replace EPDM full width of the unit.

    Heres images of how I will shore up the sagging assembly around the skylight openings. Back to back 1.5 inch aluminum angles. this wont effect headroom in the bathroom as well.

  • Thank you for that info. I read it somewhere but validation is helpful. After some deconstruction, I have a plan to repair this area and will report back once I get a way to load or link photos.

    BTW the photo faq is way old, the hosting sites in that list are not working for me.
  • I was in the plant in '04. If I recall correctly the roof is an aluminum tube frame with Styrofoam sandwiched between plywood. The floor is the same. The walls are the same aluminum frame with Styrofoam sandwiched between filon exterior and the paneling on the inside.
