Quick Roofing Question

[lindy rig]

I am building a shed.

Would you put the roof paper under or over the metal roof edge? Does it matter?

[TDH]

Over, it might not matter but thats what I was taught. When ever possible you want to make the water have to shed onto another barrier just like the shingles do. If you were to put it under water would be able to get under the drip edge to easily if the shingles were to fail.

Paper should go over the drip edge on the eaves, and under it on the gables.

Paper should go over the drip edge on the eaves, and under it on the gables.

I do the same, over the roof edge on the eves.

Gable ends I put the paper under the drip edge as it helps from having the paper get blown off.
