Build my teardrop 4 years ago. A year or so ago I found a spot on the front curve of the roof that had developed a couple a couple small cracks. The area around the cracks seemed a little soft. I assumed it was a weak spot in the wood. The roof is 1/8" thick plywood, covered in two coats of epoxy, and six coats of boat hull paint. The whole tear is finished in this way and has held up great. I covered the cracks in silicone goop and haven't had any issues since then, until now. Last weekend I noticed a couple more cracks develop above my silicone "patch". Still didn't worry my too much. These are on the passenger side of the teardrop. But then I looked on the driver side and saw too more cracks starting. The longest being 1.5" and in a direct line with the originals. So now I'm thinking it's a stress crack that may make it's way all the way across the front of the trailer. The angle of the front curve is pretty soft, so I'm surprised this is happening.
Any thoughts on a cause or a possible solution? I'm wondering if I could put a strip of fiberglass cloth across it to strengthen and seal it. I'd REALLY like to avoid rebuilding the front end of the camper. Thanks in advance.
