Chesapeake Roofers: Article About Professional Roof Fastener Applications
Simply driving a few nails into each shingle sounds like a basic contractor's task, but securing components on any rooftop requires extensive skill and experience. Chesapeake roofers must use the right fasteners and apply them perfectly to the materials for a leak free surface. Homeowners should understand the basics behind fastener types and use, so they know when their property is being serviced correctly.
A common sealant used on almost all rooftops is plastic roof cement. This sealant is a filling agent meant to work in conjunction with metal flashing. With flashing secured to a roof and penetration, for example, contractors complete the installation portion with plastic roof cement. They'll fill gaps along the flashing and penetration, ensuring rains simply flow down the surface without leaking into the structure's interior areas.
Ideally, contractors should always use nails instead of staples to secure shingles and underlayment. Staples are too narrow and short, contributing to material loss as the fasteners back out of their installation area. These fasteners are normally covered by other shingle layers as well, which protects them further from any weathering effects. Nails are usually driven into shingles using power tools, and at least four fasteners are affixed to each section.
Homeowners often use caulk extensively within the home for small projects, but roofers tend to apply this sealant sparingly.

Caulk is an excellent filling agent, but can wear down from weathering elements. Contractors use caulk in strategic areas across the rooftop. They only apply it where the sealant is sheltered from sunlight, rain and other damaging elements. Contractors using caulk exclusively instead of roofing cement may not have the experience to understand the critical wear differences.
Although most shingles simply hang down a rooftop with just nails holding the top section, contractors must install these materials with the region's weather patterns in mind. Roofing cement will usually be applied at shingle tab ends to secure the entire material flat against the roof if high winds are common. Updraft winds forced up the roof's surface won't dislodge shingles, giving them extra strength against damage and preventing possible leaks from entering the home.
Sealants and adhesives are meant to fortify solid roofing components. Homeowners should never see contractors using sealants to repair major roof damages, such as filling in missing shingles with roofing cement. Only small rooftop repairs should be corrected with sealants. If improper material usage is suspected, homeowners should discuss their concerns with contractors to verify the quality of workmanship.
