What
gradient do I need to lay guttering ?
A domestic eaves gutter when fixed on rafter brackets should be laid
to a fall of not greater than 1:350 to allow for settlement. If there
is too steep a fall, an excessive gap would be created between the lowest
edge of the roof and the top of the gutter.

I
have noticed condensation in my roof space – how can I prevent this?
The only practical way to prevent condensation is through effective
ventilation.By promoting cross currents of air, the entire roof void
will be kept well ventilated and will disperse any water vapour before
it can condense.Contact your local
branch who will be able to advise you of the most suitable product.
