What Size Roofing Nails For 7 16 Sheathing

Minimum Requirement For Roofing Nails Sticking Through Sheathing

Looking at a 2005 tile roof installation manual, it looks like the minimum penetration of a roofing nail into roof sheathing was 3/4. So If I assume 1/2 OSB sheathing, I should be able to cut the nails off with 1/4 still sticking through the sheathing into the attic. Is this correct, or am I missing something?

What Kind Of Nails Do You Use For Sheathing

nails

Using proper nails to attach sheathing will help your roof withstand strong winds. Traditional sheathing material typically comprises 15/32-inch plywood or oriented-strand-board panels. Builders generally use 8d common nails, which are approximately 2 ½ inches long and 131/1000 inch wide in diameter.

One may also ask, should roofing nails go through the sheathing? A 1nail will fully penetrate through 3/8roof sheathing, but it won’t fully penetrate 1/2sheathing. The other way to determine if the proper nails were used is to look in the attic if the roof has 1/2sheathing, you should be able to see the nails sticking through in to the attic.

Considering this, what kind of nails do you use for plywood?

Framing nails are used for plywood assembly both interior or exterior. They are referred to as sinker nails, common nails and box nails. Sinker nails have a waffled head, which makes driving them easier, and a coating over the shank to keep them solidly in place once driven.

Can I use screws for roof sheathing?

Screws can be used for even greater withdrawal strength, but should be sized by the building designer. Staples are not recommended for roof sheathing attachment in high-wind areas.

Fasten Roof Sheathing Panels Properly

Fasten panels with a minimum of 8d Common nails spaced a maximum of 6 inches on center at supported panel ends and edges. At intermediate supports, fasten panels 12 inches on center. In high-wind areas, more fasteners may be required. Fasteners should be 3/8 inch from panel ends and 3/8 inch from panel edges .

For pitched roofs, wear skid-resistant shoes.

On panels with a screened surface or skid-resistant coating, install panels with the non-skid surface up.

What Is The Best Osb For Roofing

With 24-inch truss/joist spacing, the National Wood Flooring Association recommends 1-inch OSB underlayment, compared to 7/8-inch plywood. Depending on thickness, plywood is also approximately two pounds or more lighter per sheet. Perhaps, plywoods biggest feature is the homeowners perception of higher quality.

Is Osb Or Plywood Better For Roof Sheathing

Plywood Holds the Moisture Advantage Over OSB

When plywood gets wet, it tends to swell. OSB takes longer than plywood to get saturated, but also takes much longer to dry out. When used as roof sheathing, this tendency to hold moisture means it will degrade faster than plywood when exposed to chronic leaks.

This is only slightly smaller than ½-inch roof sheathing, but some people say there is a noticeable difference in using it for roof sheathing because of its weight-bearing potential.

Can I Use 7/16 Osb For Roof Sheathing

Roof sheathing is the structural support for your roofs exterior. OSB is the most common choice for roof sheathing because of its flexibility and low price point. However, despite the popularity, some buildings require stronger support like plywood which can withstand heavier loads. This is because plywood tends to require thicker roof decking compared to OSB.

The most common roof sheathing thickness is 7/16. 7/16 is durable and maintains building integrity much longer than other sizes. Many people recommend going no lower than 5/8 thickness to maintain durability, especially when using OSB. You may notice that 3/8 is a common choice for roof sheathing, however, it is not as durable as 7/16 and does not typically abide by modern code requirements.

The APA stamping on roof decking is beneficial to determining appropriate thickness when deciding upon different roof sheathing thicknesses. Always remember the board you choose must support your roof and the weight you intend to bear on top of it. The roof decking must also be resistant to aging and heavy loads, including harsh weather .

What Is Roof Sheathing

A roof system consists of several elements working together to protect the home. Roof sheathing is one of those elements. In the U.S., it is almost always composed of woodusually OSB or plywood. OSB is lightweight, relatively inexpensive, and strong enough to resist bending or breaking should someone walk on the roof. Plywood is a bit more expensive, but is usually stronger and is often selected in cases where the roof covering is heavier, such as for slate, clay, or concrete tile roofs.

Should Roofing Nails Be Visible In The Attic

I have a colonial built in 1913 and I live in NYS. My roof was just completed today and I have exposed nails across the entire roof!

It was not like this before. When I asked the contractor about it, he said this is normal, but I’m having a difficult time accepting this answer. I have included a picture to show what the entire roof looks like from the inside of the attic.

• My house in Florida has very long nails too. They say it’s preferred for hurricanes. I even got a discount on insurance.

That’s perfectly normal. I would have preferred to see the vertical joints in the sheathing line up with the rafters, but that’s about it. Roofing nails actually should come through about a quarter inch – I’d be more concerned if they didn’t.

Most sheathing now is 1/2 to 3/4 at most and a shingle is only about an 1/8 so with that being said the distance with synthetic is about an inch. If you’re using a nail gun, which most roofers do, then your coils are 1-1/4 inch long at a low end . So, unless you’re hand nailing, yes there will be about 1/4 inch showing. It is normal for this to happen it is unlikely for there to be no nails showing unless your roof is made of planks, in which case they wont show.

Required by the International Building Code, proper nailing is essential to the optimum performance of roofing shingles. Accurate nailing requires the use of approved nails, nail-driving methods and placement .

Atlas has installation guidelines in place to ensure proper, uniform installation of Atlas shingles on every roof, whether that roof is new or recovered. Nails should have a minimum, nominal shank diameter of 11- or 12-gauge, and a minimum head diameter of three-eighths of an inch. The length of each nail must be a minimum of 1¼ inches long, and for roof-overs, Atlas recommends a nail length of at least 2 inches.

Nails of the proper length should penetrate three-fourths of an inch into the roof deck. However, where the roof deck is less than three-fourths of an inch thick, the nail should be long enough to penetrate fully and extend at least one-eighth of an inch through the roof deck.

Each shingle model has specific requirements for nails printed on each shingle wrapper. These guidelines must be followed to comply with building codes and ensure intended performance levels

All nails need to be driven either by hand or with a properly adjusted pneumatic nailer. Improper adjustment of a pneumatic nailer can result in overdriven or underdriven nails, which can cause nail corrosion, sealing failures, raised tabs, buckling and blow offs.

What Size Osb Should Be Used For Roofing

Typical types of wood used for roof sheathing are oriented strand board, known as OSB, and plywood, the most popular being OSB. Sheets of 7/16-inch thick, with no edge support, can be used in an area where the snow load is 30 pounds per square foot. With edge support and the same snow load, 3/8-inch OSB can be used.

Calculating Proper Roofing Nail Length

The length of the roofing nail is determined by the material it will be drilled into. Some materials require longer nails, while others do not need a lot of penetration and work with shorter ones.

• Some materials like sheds or garden houses have roofs which work just fine with less penetration of the nails.
• For materials like solid wood, plywood, OSB, and non-veneer wood decking, the nail should go in 19mm.
• If you are installing thick shingles or doubling the roof by adding shingles over shingles, then the nails need to be at least 30mm to 35mm long.

Nails that are properly seated will penetrate the roof deck about three-fourths of an inch. If the roof deck itself is three-fourths of an inch thick, then the nail should penetrate at least one-eighth of an inch through the roof deck.

Staples Or Nails Choosing The Right Fastener For Wall And Roof Sheathing

We are often asked by contractors if they can substitute framing staples instead of nails for their wall and roof sheathing fasteners. There is no easy universal answer to this question because the location of the project may place it in a high wind or seismic zone that may require special engineering for the fastening systems. However, according to the International Building Code, there is a fastening schedule under Table 2304.9.1 that lists the approved equivalent fasteners for nails and staples in a wide array of assemblies not subject to these special engineering conditions.

For example, according to the table, 7/16 OSB wall sheathing may be fastened with 6d common, box or casing nails OR 1-3/4 16 gage staples at 6 on center at the panel edges and 12 on center in the field . Similarly, 19/32 OSB roof sheathing would be 8d common, box or casing nails at 6 on center at the panel edges and 12 on center in the field OR 2 16 gage staples at 4 on center at the panel edges and 8 on center in the field.
