Essex County roofers have hundreds of fasteners to select from when securing materials to structure surfaces. Roofer experience and training dictates the best choices for each project, however. Generally, contractors use a mixture of nails, screws and clips to properly install any roofing materials. Homeowners should understand fastener use and proper application as roofers continue with a new installation.
The most common fastener is the roofing nail. These fasteners have long shafts with flat heads to rest flush against rooftop surfaces. Ideally, contractors must install each nail at a perpendicular angle to the rooftop to create leak free surfaces. However, poor application techniques can plague entire rooftop sections. Over driven, loose or angled nails contribute to leaks into shingles and underlayment. To combat possible leak problems, contractors must use proper air tools and application angles for each shingle section.
Traditionally, contractors installed shingles almost exclusively. Currently, material manufacturers also offer metal shingling and panels for even more aesthetic diversity among properties. However, metal materials usually require screws instead of nails for proper rooftop attachment. Contractors simply add screws to prefabricated holes along metal panel edges. In reality, these fasteners have the same installation requirements of nails.

All screws must be flush against paneling to ward off moisture leaks under metal installations.
Metal shingles or panels come in relatively large sections, so contractors must use specialized clips to keep adjacent materials properly aligned. For example, contractors install two adjoining panels to a rooftop. They continue installation by adding clips along all panel edges. Clip quantities, however, depend on panel sizes, typical weather patterns and contractor installation strategies. These clips shouldn't be visible from the ground, so installations remain as seamless as possible with proper installation.
All rooftops must have some flashing or metal pieces protecting transition areas, such as chimneys meeting shingled surfaces. As a result, flashing becomes a type of fastener. For example, contractors must fit and secure flashing against finished shingle surfaces using screws or nails. In fact, contractors choose between screws or nails based on regional weather patterns and structure shape. In the end, professionals must secure flashing to remain in place for as long as shingle lifespans.
The best fastener selections can fail if they aren't matched with proper material applications. Starter courses, for instance, must be perfectly installed along rooftop edges to prevent moisture wicking under overhanging shingles. Without proper starter course installation, fasteners will usually fail to hold materials and allow moisture to infiltrate the structure.
