When deciding on a new nail for your roof, consider the material that you are attaching it to. If you are using asphalt shingles, choose a nail with a head diameter of three-quarters of an inch. Depending on the material, you may need to add additional fasteners along the edges. When using a roofing nail, it is important to use a long shank that will penetrate a layer of plywood or asphalt shingles. Wood shingles require a longer nail. roofing contractors near me
Roofing nails typically come in 1.5-inch sizes. They have an 11-gauge shank and an oversize 7/16-inch flathead. These nails are hot-galvanized to resist weathering. Each pound of nails weighs about one ounce. During normal conditions, two and a half pounds of nails are needed for one square of shingles. However, if the weather is windy, three and a half pounds of nails are required. Roofing nail suppliers can advise you on the right nail size for your particular roof and application.
In addition to the material used for roofing, the shape of a nail also makes a difference in its effectiveness and efficiency. A smooth shank nail is most commonly used in construction sites, but it isn’t the best choice for roofing projects. A smooth shank nail is also the least expensive to produce and isn’t the most effective roofing nail. If you are planning to use a copper nail for your project, you should know its exact length and diameter.
You should also consider the type of sheathing on your roof. Wood sheathing can consist of oriented strand boards and plywood. Nails can back out along the seams if they hit a weak spot in the wood. Wood sheathing expands and contracts dramatically, and this expansion and contraction can push a nail out of the wood and into the attic. A wood sheathing has a thin tongue that makes it vulnerable to damage.
When nailing roofing shingles, screws are not a good choice because they leave tiny gaps in the material when driven in. This can let water leak in. Instead, ring-shank nails are a better choice if you want extra security. Choose nails with a 12-gauge ring shank for added security. Also, the length of the nail depends on the thickness of the sheathing and shingles.
The right size of roofing nails is critical to preventing major roofing problems. It is also critical to remember that the nails on your roof should be long enough to penetrate the entire roof structure. A three-inch nail could poke through your attic ceiling and protrude through the decking. If your nails are too short, the result can be splintered wood and cracks, which may lead to moisture and mold.
Depending on the type of roofing material, there are different types of nails. You can choose between steel nails, galvanized nails, and ring shank nails. Stainless steel nails are corrosion-resistant, and are the most popular choice for homes in coastal climates. For the best roofing protection, you should also use corrosion-resistant nails for your roof. The ring-shank nails are cheap and are best suited for flat and shingle roofs.
