Galvanised roofing members - venting requirements ?
If I use galvanised steel roofing members instead of timber, they
cannot rot. How does this affect the roof ventilation requirements in comparison to a conventional timber roof ? Thanks, Simon. |

In addition, the likelyhood of cold bridging and increased risk of condensation forming on the steel, may require greater insulation detailing on top of the steel, and around the roofspace generally dg |
