Concealed nail method
The concealed nail method is a roofing installation technique that involves securing the shingles or other roofing materials to the roof deck using nails that are hidden from view. In this method, the nails are driven through the top edge of the shingle, but are covered by the overlapping shingle course above it, which provides a clean and finished appearance to the roof.
The concealed nail method is typically used with certain types of shingles, such as architectural or laminated shingles, which are designed to be installed using this technique. The shingles are installed with the exposed nails located above the cutout, which is the portion of the shingle that is visible on the roof surface.
The concealed nail method is often preferred over the exposed nail method, as it provides a more aesthetically pleasing appearance to the roof, without visible nail heads or exposed fasteners. The method also helps to prevent water infiltration, as the shingles are more tightly secured to the roof deck and less susceptible to wind uplift and other types of damage.
Overall, the concealed nail method is a popular installation technique for roofing materials, and can help to provide a durable and attractive roof system that can withstand the elements and provide long-term protection for the building and its occupants.
