Choosing what size roofing nails to use is crucial for waterproofing and long-term protection. The length of roofing nails is determined by the material to be nailed to. While some materials require longer nails, others do not require much penetration. A shed or garden house, for example, may have a lower amount of penetration than a house made of solid wood. In this case, a 19mm nail is necessary. In addition, nails with different gauge sizes may be necessary for various layers. roofing company
Roofing nails can come in various sizes. Metal roof nails are the largest, with a diameter of about.190″. Common nails are smaller and are.08-.11-inches long. Brads are typically smaller, and range in size from.06-.09″. The size of your roofing nails should overlap the material completely. If you can’t overlap the material completely, use additional fasteners along the edges.
Asphalt shingles require fasteners with a shank thickness of 12 gauge or larger. Nails with a diameter less than 12 gauge will not meet IBC standards. Nails with a head diameter of 9.5mm or less should not be used on asphalt shingles. If you are installing dimensional shingles over existing asphalt shingles, use one-inch roofing nails. You can experiment with other sizes to see what works best for your roofing needs.
The head diameter of roofing nails is generally 3/8 inches. A larger head size might expose the nail head when used in standard nailing locations. During an IKO test, ring shank nails were found to be stronger than smooth-shanked nails. For a roof made of felt, you should use a square cap nail. They have square head sizes and either a smooth or coiled shank. These nails are often the cheapest type.
While there are several types of roofing nails, the two most common are the trim head and spiral shank. While these are both grayish in color, the latter type is less effective. In addition, stainless steel roofing nails are less expensive than their aluminum counterparts. Aluminum roofing nails may be considered “good enough” in many parts of the country. However, you must still remember that the type of nail you choose will determine how effective your roof will be in the long run.
When choosing which nails to use, it is important to consider the roof’s pitch. Normally, a flat roof needs more nails than a slanted one. You may also need additional nails if the roof is unusually shaped or has a high wind speed. To make the selection process easier, check out nail suppliers that offer professional estimates. A little knowledge can go a long way. However, it is always important to know the appropriate length of roofing nails for a particular type of roof.
When installing shingles, the size of nails used for each shingle matters. Residential roofing nails are typically three to four inches long, but the size of nails is different for more complex applications. New roofers often make the mistake of thinking that three nails per shingle or two nails every other row will suffice. But there are several variables involved and the number of nails needed for the job will depend on the type of shingles and other materials on the roof.
