Roofing Nails Through Eaves
If the nail does go through the decking it will only show if someone is hanging out in the attic.
Roofing nails through eaves. When i replaced my roof a few years ago i made sure i used the shortest possible nails because i was tired of banging my head on nails in the attic. Roofing nails must always come through the sub roofing to hold. You can just paint over them and live with the result or fill in the areas with wood covering the tips. Nails and overhangs and eaves the process of installing a roof is the same in most cases.
It s that the roof sheathing is not thick enough for the nails. You say the nails are sticking through the plywood if this is the case you are supposed to have a soffit installed that covers the underside of the roof deck. Just make sure that you don t damage the shingles lifting them up. I would suggest to remove the nail and put a urethane sealer which can be found at any home store to seal the hole from underneath.
Roofing nails should be long enough to penetrate the roofing material and go 19 mm into osb solid wood plywood or non veneer wood decking or through thickness of decking whichever is less. I m getting my house painted in a few weeks and i want to cut off all the tiny nail points under the eaves. Remove nail lift shingle and apply a small dab where nail penetrated shingle then push the overlapping shingle down and your done. Relax have a drink.
Your contractor is correct in his interpretation of the national roofing contractors association standards as well as the ohio building code which state that nails must be long enough to penetrate through all roofing materials and extend through the underside of the deck or penetrate a wood plank by of an inch even if that surface is less than inch thick. In determining nail length consider the number of layers of shingles shingle thickness es underlayment and flashing eaves sidewall and valley etc. If you do glue the wood with construction adhesive. If the deck sheathing is less than thick use nails long enough to penetrate the roof deck sheathing and extend at least 1 8 beyond the lower side of the roof deck.
However i failed to notice that the nails are poking thru the eaves about 1 8 to 1 4 inch. Don t use nails or you will poke through the roof. Even if the attic is a living space they are covered up with insulation and then drywall.
