Re roofing barns if the outside of a barn has experienced severe structural damage it must be decided if only a portion needs to be replaced or if the entire structure should be completely redone.
Re roofing a barn.
Hi i am contemplating re roofing my barn which has a 40 year old galvanized corrugated metal roof on it.
Position the roofing felt at the bottom left hand corner of the roof.
Unroll the felt a bit at a time working from left to right making sure the felt is flush with the edge of the roof.
However a tin roof will have to be replaced sooner than other sorts of metal roofs.
The existing roof is laid directly on purlins on about 3 centers with no roof deck.
The existing metal sheet is not in super bad shape but is definitely pretty rusty in some areas and is curling up in others.
This is the least expensive form of metal roofing.
