roof ends

[soccer55]

I bought a 1989 Jayco KB1207 pop up. I have found that the wood panels along the roof where the canvas support locks in have rotted away. I would like to replace it with marine plywood. How do I get to the wood. It is covered by fabric on the inside. Any help would be appreciated.

It should be available from Menards, Home Depot, type of places.  Several not so good things about marine grade to mention.  Heavy and expensive.  Exterior grade plywood with a good primer would work well.

Just my 2 cents.

To get at the wood on the interior, you'll have a few screws to remove up along the top of the canvas by the roof, that should allow you to pull down the canvas to expose the wood on the roof boards.

I just replaced the wood sides on my 1993 Jayco Eagle...can't wait for my new Bearcreek canvas.  I had to do the sides and the ends.  Hopefully you do not have rot in the corners and can just replace the ends...they are easy.  The side pieces are more work.
  Another thing about Marine grade Plywood is that it is usually CDX.  Meaning C grade side and D grade side with X exterior grade glue.  CDX grade plywood usually has a lot of voids in it.  The voids are usually cut out and filled with a biscuit "football" shape.  I apoligize if you know all of this already but if you have voids you tend to have a weak spot.  Usually voids are only filled on the outside layers, the inside are not.  The other thing about CDX is that it is usally only 3 plys.  Chances are your ends are out of 1/2" plywood.  If you get another grade of plywood like AC or BC sanded you will find that it is a better finish it has no voids and it usually will have 4 and sometimes 5 plys.  I was able to find 4 plys and it seems like it worked well.  I was going to go with the PT ply wood but it was only 3 ply and I knew the voids would give me trouble.  I was able to brace the corners with some TECO braces.  If you go to HD or Lowes the braces are in with the decking fasteners.   I almost was going to go with Furniture grade plywood it has like 6-8 plys depending on its thickness, and man is it strong stuff.  My local lumber yards did not have it and it is sometimes pricey, and it usually is not put together with exterior grade glue.  Just my .02 but I would stay away from the PT plywood.

Thank you for the info. I was looking more for information on how to get to the wood. You did the sides and ends. The interior fabric is wrapped and tucked inside the ends. I am looking on how to get to the wood.

Mine only had a valance which was attached to the ceiling.  I just pulled the valance down and we are going to be replacing it.  If yours is wrapped around it is different than mine was.  You may have to cut it to remove it or maybe someone has something like yours.  Mine has a trim strip which is made of aluminum that wraps around the entire camper roof along the bottom.  It has pieces of rubber gasket which seal against the base when it is closed.  If yours has this strip there are scews under the rubber gasket which need to be removed to get to the plywood sides and ends.
