Leak-Proof Roof Hatch and Fan Openings

[Pam Garlow]

Very nice job, and excellent documentation. I think the curbing is brilliant, and when combined with proper maintenance, it will not leak. I would think that by building up the curb, the opening has been reinforced, so less flexing around the vent.

A properly done putty tape sealing job should last a minimum of 5-7 years with many lasting more than twice that long. Do we have any such history on this stuff in a tube?????

Most leaks are found on trailers that have not been maintained in even a reasonable manner. Joe buys a used trailer and, 2 years later finds a roof leak in what is now 15 year old putty, and declares that "Putty Tape is No Good" and piles on some other untried goop-in-a-tube that seals the leak, for a while.

When I removed the windows when I repainted my Hunter they had not leaked and the edges of the putty still showed evidence of the repaint color that was applied over 30 years ago.

My Rule #17: When I buy a used trailer I reseal everything on a horizontal surface and anything on the sides except the windows with putty tape. Windows I inspect carefully and remove and reseal with putty tape if there is any evidence of silicone type sealers gooped around the edges.
