Wondering if it is acceptable to use 3/4" beadboad plywood on my porch roof so that I get the beadboard look underneath, but have exposed beams. I would put shingles on top of the 3/4" beadboard plywood. Is this something that people do? Is the 3/4" beadboard plywood durable enough for roofing applications? Thanks.

you can do that,but you need too probably hand nail the roofing on with 3/4'' roofers,the smallest gun nail i believe is 1'' and will penetrate through the beadboard sheathing

What I might do is cover the 3/4" beadboard ply with 1/4" or 11/32" OSB and then use 1" or 7/8" roofing nails. Thoughts?

got an even better idea...less expensive. Use 1/4" beadboard ply first and cover that with 3/4" OSB. Save some money and get the same effect.

place down your boards then sheet the roof with plywood, chalk your trusses so you dont nail through into your fancy beadboard ;). depending on anything less then a 4-12 youll need to use ice and water underlay. but thats your discretion.

Hello,
I know this is a very old thread, but I'm wondering how the beadboard has held up to heat being attached directly to the porch roof sheathing.

On my screen porch project, I'm considering applying 3/8" beadboard on top of the rafters, then 1/2" plywood followed by tar paper and shingles. I'm just not sure if the summer NC heat coming through the rough will damage the beadboard?

Has anyone done this?

strubles right.. the only way osb will turn into that mess is if the roofer makes every attempt possible to make sure water does get in under the shingles and ice and water shield....
