Best roof membrane to use?

[jaythegorilla]

Hello

Joiner is due to build the frames of my 3 dormers on hip roof next week. He will make them temp. water tight with membrane, roofer was due to strip, re batten, re tile roof etc week after.

To cut a long story short, looks like i will have to attempt re roof myself.
So if anyone could suggest which type and make of roof membrane i should be laying i would be very grateful.

Many thanks in advance.

Hello,
Most breather felts do not 'seal' around the nail as with traditional bituminous felts and consequently can be prone to letting water in under heavy prolonged rainfall, until the roof is slated/tiled.

However there are a couple of breather felts on the market that do seal around the nail giving much better waterproofing qualities if the roof needs to be left exposed for any period, these are also particularly good for using on boarded roofs.

The one I would recommend is 'Proctor Roofshield' which we have used many times, the extra expense has been well worth it.

Regards
Jon

Or Klober Permo forte..Very Good.

seconded - klober permo is excellent and reinforced..

Dont be tempted by budget breather membranes as they are like tissue paper, cromar vent 3 for example is awful.

Klober Permo Forte the best I reckon too. Make sure its the 'forte' and not 'eco-vent' though.
