We're wanting to replace our rotting wooden porch/conservatory with
upvc and the plastic roof with glass and have a couple of quotes.

There are two items that the installers are not interested in covering
and I don't mind doing myself if there are some good ideas
forthcoming.


2) The porch is about 3m wide x 1.3m deep. Probably the main reason
that the wooden porch has rotted is that no-one thought to deal with
the water run-off from the roof. It only needs to be diverted to the
left onto the garage roof which in turn is designed for water to run
into its gutters. Neat ideas for this bearing in mind I'm aware that
we're not going to have the same rotting issue with pvc.

Lots of responses on Item 1 and nothing on the water run-off - surely
someone's got a brainwave.

Judging by what our reasonably reputable roofers did (with slate roof)
just run a short downpipe from the end of the conservatory gutter as a
spout either into the garage gutter or to intersect the garage roof at
less than 90 degrees a couple of feet above the gutter. It may require
a 135deg bend to do this.


It's not the downpipe that is my concern as the porch roof is higher
than the garage roof - I just want an unobtrusive way of getting from
the nice glass roof to the top of the the adjacent garage roof and all
guttering seems to be an overkill size of 3".

Try green house suppliers. Extruded Aluminium in 3m+ lengths.
