Exposed nail method
The exposed nail method refers to a technique of fastening shingles or other roofing materials to the roof deck using exposed nails. With this method, the nails are driven through the surface of the roofing material, and are left exposed to the elements.
The exposed nail method is a commonly used technique for installing asphalt shingles, as it is relatively fast and easy to perform. However, this method can present some potential issues, as the exposed nails can be more susceptible to damage from wind and other types of weather-related stress. Additionally, the exposed nails can be more visible on the roof surface, which can affect the overall appearance of the roof.
In contrast, the concealed nail method is another popular technique for installing roofing materials, in which the nails are driven through the roofing material and are then covered by the overlapping shingle courses. This method can provide additional protection against wind damage, as the nails are not exposed to the elements, and can also provide a cleaner and more uniform appearance on the roof surface.
Overall, the choice between the exposed nail method and the concealed nail method will depend on a variety of factors, including the type of roofing material being used, the climate and weather conditions in the area, and the specific needs and preferences of the building owner. Proper installation and maintenance of the roofing system is essential, regardless of the installation method that is chosen.
