Alpha Systems roof membranes are common on Jayco trailers. This is some of what they say about maintenance and repair.
RECOMMENDED REPAIR METHOD FOR ALPHA SYSTEMS
During routine cleaning (3-4 times a year), all caulk and sealants should be inspected for voids or cracking. If the caulk is cracking, pull up any loose caulk. Do not use any tools, such as a putty knife, that could puncture the rubber roof membrane. If you cannot pull the caulk off by hand, it is still adhered to the roof and should be left alone.
Clean the areas to be re-sealed using regular soap and water. The area must be dry before continuing.
Apply a generous amount of sealant over the top of any existing caulk in the area being re-sealed.
Solvents should not be used during cleaning. Solvents can damage existing caulk and may weaken plastic parts that are present on the roof.
