Mattoon Roofing: Article About Proper Shingle Nailing Techniques
Shingles may be one of the simplest roofing materials to install, but shingles also require a lot of specialized fasteners. Roofing nails must be applied in the right quantity and location to securely lock a shingle into place. From concerns about wind uplift to possible leaks, homeowners should be aware of all shingle fastening strategies to be confident in their overall installation.
Each standard shingle has three tabs with a long, horizontal connecting section. Mattoon roofing contractors must add four nails at minimum to each horizontal section. They should be spread out across the section to hold the shingle tightly against the structure. Even one missing nail could encourage wind to pull the material upward with leak possibilities. For steep slope applications, six nails should be used. The extra two nails hold the shingle even more securely to the structure because high winds can easily blow these sections off.
All shingles have cutouts between the tabs, creating an aesthetically pleasing appearance from the ground. All nails should be at least one half inch above these cutout areas. If roofers add nails too closely to cutouts, the penetration might tear down to the opening. The shingle becomes misaligned and could tear off in high winds.
A self sealing strip is part of every shingle backside.

This adhesive strip allows the shingle to hold on to the surface temporarily so that roofers can nail it down. However, nails shouldn't be driven through the strip itself. Fasteners damage and possibly lift the shingle from its flush position on the rooftop with strip penetration. The strip must act on its own with nails surrounding its location. With adhesive and fasteners, each shingle can last up to 30 years without any lifting or detachment.
Steep slope applications pose unique challenges for roofers, so they rely on adhesive strips, fasteners and roofing cement. As shingles are laid and nailed, contractors will typically add a small amount of roofing cement under the tabs. This installation strategy prevents shingles from lifting with winds passing across the surface. Roofing cement isn't necessary for standard pitches because winds aren't as volatile across the structure.
Don't be tempted to try a roofing job as a novice. Professionals survey each roof for specific challenges and variations from the norm. Flat, steep and standard roofs must have a distinct shingle design that only a professional can install precisely.
