Getting nearer the top! Was rained off today but have spent the time looking at roof trusses.  Also Gary from Cavitytrays came out yesterday to measure up for the bespoke peice which goes between the old and the new! Whatva great service! ( will let you know if I still think that when I have had the bill!) His trip was worthwhile, he has probably convinced me to with their grp valleys as opposed to lead.
