Our porch - which is on the North facing side of the house - has such a
roof seemingly fitted by the previous owners. The porches on all the other
houses in the area have fallen down, look awful or have been replaced. I
did some extensive reconstruction a few years ago - but that was to repair
damage that had obviously occurred prior to the glass fibre roof being
installed. (That is, the installers must have failed to repair everything
when fitting it.) The roofing itself must be around ten or more years old
and is still in a pretty good state. I did find that a tiny area where it
went up the wall had not been finished so well so that too needed some
In summary, for us it is excellent. Being such a small area might help to
avoid problems that would only occur on larger areas - so keep researching.
We have a glass fibre roof over our extension and a glass fibre roof on our
sun lounge which is also our balcony floor.
Highly recommended compared to your average felt roof - no problems walking
on it and so far (seven years or more) no signs of any problems with water
We live by the coast and there are loads of glass fibre boats, which seem to
last pretty well.
Couldn't envisage building a boat of roofing felt :-))
In summary, a bit more expensive but IMHO much more robust and likely to be
much longer lasting.
P.S. be sure to employ a reputable roofing contractor - remind me to tell
you the bird seed story some time :-)
Just had a big one done. It's good - but I had to go to a lot of
trouble to get the company to make good some shoddy work at a corner,
which would have leaked. I recommend the method - but as usual you have
to ensure work is done well. Tip: don't pay *anything* until completely
satisfied - that at least gives you some leverage.
I fibreglassed my flat-roofed extension six or seven years ago - no
problems since. I bought the stuff from Glasplies in Southport and did it
I just used plywood, sealed with resin, covered with matting and more
resin, followed by tissue and more resin and finally coated with a coloured
(grey) resin containing wax.
At the time I was told that the colour helps prevent UV damage and the wax
is necessary to get a non-tacky finish, as the surface won't set properly
in the presence of air (the wax rises to the surface and gives an airtight
It cost me 200 odd quid to do a 19' x 9' roof, but it is a horribly messy
and uncomfortable job!
