What are the best nails for roofing?
Stainless steel nails are good for fastening tiles and slate. Galvanized roofing nails, or steel nails coated in zinc, are perfect for asphalt shingles, and they hold up well against rust. Aluminum nails should be used for surfaces made out of metal and siding.
What size roofing nails should I use?
NRCA does not recommend the use of staples for fastening asphalt shingles. Roofing nails should be round-headed, sharp-pointed 11-gauge galvanized steel or the equivalent corrosion-resistant roofing nails. Nail head sizes recommended are 3/8-inch to 7/16-inch diameter. Nail heads should be low profile, smooth and flat.
Do you need galvanized nails for roofing?
Roofing nails tend to be galvanized, a process that makes stainless steel resistant to rust by coating it in a layer of zinc, which does not rust. Galvanization is very important when it comes to roofing nails, but even here you need to be careful because there are different types of galvanization.
Should roofing nails go through the sheathing?
It is crucial that roofing nails of the correct length were used to secure the shingles. The sharp tip of the roofing nail should pass through and extend approximately 3/8-inch past the underside of the roof sheathing.
Can I use 1 inch roofing nails?
If you’re using typical architectural shingles and 3/8-inch-thick sheathing, you’ll need 1‐inch nails. If your building codes require thicker sheathing, you’ll need 1 ¼-inch nails. When installing thicker shingles, you may need to use a longer nail in order to penetrate the OSB beneath fully.
Are stainless roofing nails worth it?
Since they’re stronger, nails made of stainless steel are sometimes preferred for fastening harder roof tiles like slate and ceramic. Overall, stainless is a good but not great nailing option for your roof. Better than aluminum, but not as great as the next choice…
Which is better roofing nails or staples?
Staple guns are smaller and better balanced. Coil nail guns are literally fed with a coil of nails, and the holder for the nails makes the gun much bulkier. Staples are far less prone to jamming up in a gun than nails. Staples cost less money.
Is it better to hand nail shingles?
Some roofers believe hand-nailing shingles gives them more control over the process. They can use “feel” to determine if the nail is deep enough and in the right location. Since hand-nailing takes a bit more time, they have the chance to correct any mistakes on the spot. On the other hand, labor costs will be higher.
What material are roofing nails coated with so they won’t rust?
When the nails come out of the molten zinc, they also have an additional coating of pure zinc on them. Zinc doesn’t rust, and the coating protects the steel from the ravages of water.
Do Galvanised nails rust?
Galvanised nails have undergone a galvanisation process which involves covering them in order to form a protective barrier making them highly resistant to rust and corrosion, and the ideal product for outdoor uses.
What does a 4/12 pitch or a 12 12 pitch mean?
Roof slopes are most commonly defined by the rise-over-run ratio. If a roof slope “rises”, say, 4 inches when measured 12 inches along the bottom of a horizontal roof truss, the roof slope is said to be 4:12; i.e., 4 inches of rise per 12 inches (one foot) of run.
How long do Galvanised nails last?
A key benefit of using Hot Dip Galvanizing is its durability. Data shows that galvanizing can provide between 34 to 170 years of protection for steel.
Can a roofing nail be too long?
Yes, they can. If they are too long, they will protrude through the sheathing at the roof overhang and be visible. We call these “shiners.”
Can you nail through shingles?
Is It Safe to Nail the Roof? Driving even a single nail into your roof can compromise the entire system. Nailing will puncture the shingles and underlayment of the roof, creating a hole where water can enter when it rains. Keep in mind that even the smallest leaks can result in expensive roof repair costs.
How can I cover my nails in the attic?
Leave a hardhat or bump helmet (lighter version of a hardhat) by the attic hatch. Put it on when you enter; take it off when you leave. I stick a wine cork on each nail. Thin (1/4″) plywood or OSB across the bottom of the rafters would work well.
