Yes, I'm in the UK and at the moment it's very frosty and cold. Meanwhile, I have the local agent of Icopal/Anderson roofing materials coming in the next couple of days. They offer a free service whereby they assess the roof and come up with a spec for its renewal, obviously centred around their own products. It'll be a good opportunity for me to get his comments on the proposals already obtained.
I also spoke to the technical people at Ruberoid and they too said that, certainly along the side joints, there should be no problem getting a good joint with mineral-faced capsheet, although they admitted that on cut edges care obviously is needed.
