For best performance, you should use ring roofing nails that are made of hot-dip galvanized steel. Must use 12 gauge or thicker. The length of the nail you use depends on the thickness of the coating and the tiles you use. You must use 6 nails per asphalt shingle to properly adhere all materials to the roof surface.
The six-nail requirement is especially important for high wind shingle application areas where a pattern of 5 nails per shingle would not be enough. Some roofing nail materials are more suitable for certain geographies than others. For example, if you live in a coastal area where your home is exposed to salt, stainless steel roofing nails may be a good option. Galvanized roofing nails tend to resist rust formation and are a suitable choice for asphalt shingles.
Owens Corning requires the use of galvanized steel, stainless steel or aluminum nails to fix the roof tiles. Atlas has installation guidelines to ensure proper and uniform installation of Atlas shingles on each roof, whether the roof is new or reclaimed. Nails must have a nominal minimum shank diameter of 11 or 12 gauge and a minimum head diameter of three-eighths of an inch. The length of each nail should be a minimum of 1¼ inches long, and for roofs, Atlas recommends a nail length of at least 2 inches.
Roofing nails come in a variety of lengths to meet a variety of needs in the roofing industry. Approximately 70% of roofs in the United States are made from asphalt shingles, and most roofing nail guidelines use asphalt shingle as a standard. For attaching asphalt shingles to a standard deck, nails can range in length from 1 inch to 2 inches. However, some applications may require longer nails up to 6 inches long.
Those longer nails are unlikely to be needed for residential roofing, and as a result, are hard to find at local roofing supply stores. Please note that as the length of the roofing nail increases, so does its caliber. You should not use smooth shank roofing nails because they do not have the necessary grip for architectural shingles or any other type of roof tile. Typically made of galvanized steel and larger than a standard nail, ring shank nails hold felts and asphalt roofing shingles exceptionally well; however, due to their relative forcefulness with alternatives, they are known to create tension.
Estimating your roofing materials is key to your success, so you'll want to know how many nails you'll use in a square. Stainless steel nails are best used for slate and ceramic roofs or asphalt tile roofs in coastal climates. Screw shanks have the highest level of pull-out strength of all the different nail classifications that exist, but despite being superior supports, screw shanks are not the most popular nails for roofing replacement. If you use a nail gun for your roofing project, the same box sizes are available and you should look to buy electro galvanized roofing nails for all nail guns.
As they are stronger, nails made of stainless steel are sometimes preferred to hold harder tiles such as slate and ceramics. Most building codes also allow 11 or 10 gauge roofing nails, as they are thicker and stronger. These types of nails are the “good enough” type used for simple roofing projects in many parts of the country. The last thing you want for your beach area home is to find shingles that are missing from a 5-year old roof, simply because aluminum was used instead of a stronger stainless steel option.
A roof square has about 100 square feet of roofing material, and a package of shingles covers about ⅓ of a square of roof. These are good options for asphalt roofs, as they can withstand bad weather and make the roof stable. Roofing nails are usually placed no closer than 1 inch from the edge of the tile according to the manufacturer's specifications. The correct installation of roofing nails is important for a house, because these facilities determine how waterproof the roof would be, and also to ensure the overall long-term protection it will provide.
To calculate the appropriate length of roofing nails, add the thickness of the shingles and subfloor to the thickness of the coating. We'll guide you through the types, sizes and materials you can choose when choosing a roofing nail. . .
