Roofing Nails Through Eaves

Nails placed outside the common bond area can void the roof s warranty and prevent asphalt shingles from performing as intended during extreme weather.

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. I m getting my house painted in a few weeks and i want to cut off all the tiny nail points under the eaves. To determine the nail length you should consider the number of layers of shingles shingle thicknesses underlayment and flashings installed on eaves. Even if the attic is a living space they are covered up with insulation and then drywall.

The process of installing a roof is the same in most cases. It takes two missed opportunities for this to happen. Luckily i live in the desert and we ve had a long drought so probably the only damage has been cosmetic. If the nail does go through the decking it will only show if someone is hanging out in the attic.

Overhangs and eaves are a different story. Nails and overhangs and eaves. Placed nails go through two layers of shingles penetrating through the previous shingle course underneath attaching them securely to the roof deck. Now it is riddled with nails although it does have a mighty fine roof i must say.

Pneumatic nail guns are popular. 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. These nails protrude about a half inch and are visible. Any roofer salesman or roofing contractor should know that exposed overhangs should not have nails sticking through them and it doesn t take a rocket scientist to determine if they will come through.

First the guy that evaluated the roof could have stopped it and then the roofers. What do i do about roof nails whose tips are showing through my eaves. 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. In determining nail length consider the number of layers of shingles shingle thickness es underlayment and flashing eaves sidewall and valley etc.

The house was reshingled about ten years ago and the guy used nails over the eaves and porch overhang that were too long. I bought the shortest roofing nails i could find 7 8 but still a bunch popped through starter course and many more just made unsightly bumps in the under side of the sheathing. I intended to have the osb be the finished ceiling inside the fort.
