Lead roof venting

A customer asks about venting a lead roof Spired on by my Youtube vide Lead Roof Venting Lead is beautiful & cross venting vital for a cold deck roofs. Warm deck usually avoids the need for cross venting but I notice that the LSA & other lead sheet groups recommend cross venting even a warm deck flat roof where this should be unnecessary for a warm deck roof. What is your opinion on providing yet another set of counter battens & decking on top pf a warm deck roof when lead sheeting is applied rather them single ply? Have you ever seen or experienced internal sweating of a lead sheeted warm deck roof? Is it an over precaution when using lead? What is your view from the sharp end? Surely if the visqueen FB vapour barrier is applied well under the insulation & sealed to all the abutments, cross venting the top side of a warm deck roof should be totally unnecessary. REPLY The perfect flat roof is a warm deck roof with a cold vented roof over the top. The cold vented roof allows any moister that gets past the warm roof to escape basically you are building in redundancy into the [...]

Hybrid roofs explained

I explain what a hybrid roof is and how to make one I’m frequently asked if I install hybrid roofs and do they work. In this video, I try to explain: what makes a hybrid roof how a hybrid roof differs from the standard cold roof or warm roof constructions, which are widely used in the building industry the different ways you can form a hybrid roof. A hybrid roof is a mixture of a cold roof and a warm roof construction. If you are constructing a cold roof – If you totally fill the void between the joists with insulation, it’s a hybrid roof. You don’t vent the roof, it’s a hybrid roof. Or you don’t use any insulation at all, it’s a hybrid roof. Or a warm roof – I’m often asked if some insulation can be put inside the roof and some outside the roof. If you do, it’s a hybrid roof. However, if you only place a small amount inside and have at least 3/4 outside this will probably work, but it’s still a hybrid roof! You definitely can’t have more insulation inside, and less outside that just won’t work. Having different layers of insulation with air gaps under a warm roof will be a hybrid roof, and [...]

OSB Expansion and contraction do I leave a gap?

Expansion and contraction in OSB is not a problem ( I think) As far as I know, no gaps needed in 18mm T+G OSB the expansion is built-in. The lower part of the T+G this doesn’t meet the other side; however, the top use so I don’t understand how that works! I know they are moving over to a new under T+G soon, but that’s all I know. I’ve tried reading the BS EN 1995-1-1:2004+A1:2008 Eurocode 5: ( 145 pages but went to sleep) Tongue and groove do I leave expansion joints The expansion per meter if it gets damp is recorded at.03mm so it’s not much we always leave a perimeter gape of 10 mm and push the bards together lightly; some never go tight as the edges are fragile and brake and bind. I’ve covered roofs over 100 m² and never had a problem, that said we don’t put rigid roofing material on the roof its normally rubber. I get lots of complaints from people that have had GRP glass reinforced plastic flat roofs installed. They constantly complain about the banging noise that comes from the contraction and expansion. Nobody seems to know if this is because of how the boards have [...]
