Thornton Roofing: Article About Roof Material Fasteners
When Thornton roofing professionals service or install any materials, they must use proper tooling and techniques to ensure a solid, finished product. Rooftops cannot be loosely fastened because winds will eventually pry materials from the structure. From nails to specialized screws, various fasteners are used by professionals to hold rooftops steady over several decades.
Nails are the most common fastener used on any rooftop. They must be long enough to pierce shingles, underlayment and decking, however. A strong rooftop installation displays short nail tips extending through decking into soffit areas, for example. Nails must also be added perpendicularly to the shingled surface to reduce possible leaks. When nails are driven at an angle or too far into materials, accelerated deterioration begins almost immediately. Nail guns with torque control allow roofers to efficiently add fasteners without any issues along material surfaces.
Flashing is used throughout a rooftop to protect transitions, such as valleys and penetration locations. Nails are often used to hold flashing down, but they can pull out over time. Experienced contractors usually rely on screws to keep metal pieces in place. Screws have threads that grasp support beams as they're being driven into place.

These fasteners hold tight to structures, reducing possible bent flashing and leaks into the interior. When nails and flashing are combined, contractors must frequently inspect these areas for any deterioration at each appointment.
Along roof peaks or ridges are specialized shingle caps. These coverings allow water to strike the ridge and fall to either side of the structure's slope. Ridge caps must be fastened with nails along each side of their rectangular shape. Most nails are covered by adjacent caps lining the peak, but contractors often go further with their installation strategies and coat nails with roofing cement. Both material layering and roofing cement contributes to fasteners remaining in place even through the toughest weather.
When homeowners want to upgrade their rooftop from a shingled installation, they often choose metal panels. Because of its weight and size, metal roofing must be secured with screws. These fasteners hold metal tightly to decking and rafters, giving the home a strong barrier to leaks.
Along with windy rooftop concerns, contractors must also be aware of material thermal resistance. Hundreds of nails are available for construction use, but not all of them can withstand excessive heat and cold along a rooftop. Experienced contractors work with galvanized fasteners and other specialized materials to make each rooftop as strong as possible.
