Fixing a rubber roof (help!)

Posted by on November 14, 2006, 8:07 pm

Ok, I have a slightly sloping rubber roof (12x12). It is an old roof,
and it is now leaking both by
the 'drain' (middle of the lower side of the roof), and next to the
house (this roof covers a single 'addition' room that will be demoed in
3-5 years).

>From visually inspecting the

areas, I cannot detect any obvious holes/tears. To further complicate
things, when I look from the 'underside' of the roof (it leaks into an
office with a suspended ceiling - so I removed some of
the panels to try to find the leek, well can't do that (tar paper under
rubber) so am trying
to figure out an 'easy' way of doing this.

I tryed to seal some of the seams with tape and also the EMPD(?) rubber
paint - it is very expensive
and difficult to work with (too thick).

Ideally, there would be an inexpensive 'paint' that would simply plug
all the holes when it dried -
I mean there must be a _simple_ solution.

Help me usenet gurus!

When I found some holes in my flat rubber roof, I just used a dab of
roofing cement. Works like a charm and cheap. But the leaks caused at edges
are tougher to try to track down ,especially if you get ice backup.

Use this on the seams:

It's relatively cheap and weathers well because it's vinyl.
Take a pair of scissors and cut the hose length wise until
you get the desired length. Purchase trowel grade roof tar
as opposed to brush grade. Lay a layer of the trowel grade
roof tar on top of the seam that is slightly wider than your
prepared vinyl tape. Apply the tape. When stable apply another
layer of roof cement on top of the vinyl for the purpose of
extra leak protection and protection of the vinyl from the sun.

It will last forever.

To get by for a few years on a basically sound roof, buy and
install an elastomeric roof coating. Goes on like paint, needs 2
or more coats. I have had some great results. Look for one
compatible with epdm as I have not used it on an EPDM roof.

Keep the whole world singing. . . .
