My roof repair

[Cougarkid]

Double,


Just read the thread on your roof repair. Looks like you are doing a fine job.

Noticed you stated you are going to liquid rubber it when the wood repairs are complete. Are you going to put down new rubber roofing and then coat with liquid rubber? Or just coat the wood with liquid rubber?

I can tell you from experience that the liquid rubber roofing WILL NOT work over exposed wood. It will work great for a bit, but the wood is not an approved substrate for the liquid rubber. After a short period of time, moisture will permeate thru the liquid rubber roofing and you will develop leaks. Been there, done that.

i am about to re-roof our older Rv for the second time. Did the liquid rubber roof over wood - supply house I was to get my white epdm from only had black in stock. They talked me into the liquid rubber - I bought in. Worked great for about a year.

The leaks started. Worst part is you couldn't tell where the water was getting in at. Water dripping in the cabinet onto the plates was getting in 6 feet away on the roof. I recoated the roof and stopped most of the leaks but they came back again.

If you are set on the liquid rubber, at least patch the repaired spots with epdm or vinyl before you coat the roof. Don't want to see you have to redo your repairs down the road.

Hi Mike,
No I am patching my existing roof and then coating with Liquid Roof. I would never try to just coat wood. Chemist may be good but they aren't that good. Too much movement of substrates in an RV. These are pictures of my patches.



Here is the last photos of the latest patch.

Did you have to make any repairs on the inside? Pics?

Pics are backed off onto an external hard drive. I am out of state right now.

Some ceiling spots required attention, but not too bad. Passenger side front corner was a mess.

We stripped the siding (1-piece fiberglass) off of the entire Rv and replaced all the luan on the walls. Rebuilt the fronts corners with new foam and plywood. Arched the roof to get an inch height in the middle for drainage. Rebuilt the entire back wall from top to bottom.

Older Georgie Boy Rv. It was down to the box frame and foam on the outside. Basement doors were all off. Only the windshield was left into place.
We were in a borrowed garage, really tall and big. I had to pull it out and turn it around while it was stripped down.
It was like driving a box. No mirrors. Had to rely on directions from others.

Reglued the siding on, put the windows back in and hung the basement doors. Painted the liquid roof on and put the drip rails on.

Really wish I had gotten the edpm roof on. This time I will!!!
