Question

The roof at the front of the trailer is leaking at 3 or more of the seams.  The front seam is where the fiber glass and steel meet.  I've tried a sealant from an RV repair shop and also the as seen on tv flex seal.  Neither worked well, if at all.  I live in the mountains of Colorado so there are wide temperature fluctuations.  I want to insulate and put up walls inside the dressing area, but can't even leave a mattress inside because the roof leaks.  I keep it covered with a tarp when not in use.  What is the best material to seal and waterproof this roof that will last for a long time?  What kind of prep needs to be done?  Thank you.

Answer 1

Sure the liquid roof can go directly over fiberglass and steel.  Here are the specific substrates and their limitations

• Stainless steel-Only if sanded
• Neither the primer or Liquid EPDM can be applied to glass
