To repair it there are two primary methods.
Replace insulation in pole barn roof.
This is not only because of the metal costs.
It ranges from r 5 to an r 16 value depending on the type.
In a non insulated pole barn there will be a large amount of heat transferred in and out.
Above the roof trusses this choice comes with new construction or a roof replacement.
I want to start insulating my pole building.
Steel roofing is a highly conductive material in terms of heat transfer.
The higher the r value the higher the insulation capacity.
R values indicate the insulative properties of the material used.
Pole barn or post frame buildings are typically constructed using wood framing with steel roofing and siding.
When insulation for a pre engineered metal steel building is originally installed it is compressed between the wall or roof panels and the roof purlins or wall girts.
For budgetary purposes plan on roughly 2 3 per square foot for the materials to repair pole barn roof leaks.
Thank you mike the pole barn guru responds.
Larger barns are going to cost more to recover than smaller barns.
One is to remove the panels remove the old insulation and replace it with new insulation.
30x40x16 roof layers are metal synthetic underlayment osb 2 8 purlins.
The fiberglass insulation used in this method can be as high as r 13 insulation thickness on single layer systems range from r 7 to r 30.
The actual length of the steel and number of pieces will depend upon roof slope and overhangs.
Has an open ridge vent.
My question is can i leave an air gap between roof and insulation as i plan on using r19 batting and covering with facing.
The size of the barn also plays a large part in the cost of the roof replacement.
Similar to the repair on the column you can also do the same with a truss.
One or two inch insulation can be placed on the exterior of the building underneath the steel.
You should also replace the ridge cap rake trims ridge and eave closures and reflective roof insulation.
If a tree has fallen and smashed the roof on a building you can put up a truss alongside the existing one where it s damaged.
Labor additional materials insulation and even the pitch of the roof can all play a part in the final cost and that will vary depending on the size.
Here the insulation is placed between the inner purlin supported by the truss and the outside metal panel.
