Hi, we want a steel rood for the cottage. We had several contractors come and quote. All but one want to use 1x4 strapping. One wants to do
2x4. What would be the benefit of using the 2x4, other than the price difference. We have cathedral ceilings, with one side sloping toward North. Winds can be strong, but are slowed down by huge spruces that grow on that side. Thanks Folks!
