Virginia Beach Roofing: Article About Shingle Alignment Procedures
As homeowners look over a brand new roof installation on a neighbor's home, they'll notice the intricate layering and alignment necessary to complete the project. Virginia Beach roofing professionals must use certain strategies and tooling to make a shingle installation consistent across the entire surface. Any exposed or misaligned areas only contribute to leaks and roof decay.
With all roofing materials removed and the deck carefully inspected, contractors create horizontal straight lines across the surface using chalk lines. A roofer stands at one end of the roof with another person directly across from them. They'll stretch a specialized string dusted with chalk between themselves. Holding the string close to the roof, a third roofer snaps the line down. An instant straight edge appears across the roof. This visible line provides an alignment edge for all starter shingles. Contractors may continue up the roof to create more lines for the remaining shingle courses.
All contractors have different installation strategies, but many companies also insist on vertical alignment lines. Roofers will perform the same snapping maneuver in a vertical orientation. This tactic provides alignment for shingle cutouts. Without proper shingle alignment, leaks are almost unavoidable as crevices provide a pathway for moisture to the wood roof deck.
Homeowners should notice all shingle courses being laid with a staggered appearance.

Cutouts or shingle gaps should lay just above the tab's middle section. Contractors will cut shingles at their side edges to create this staggered installation. Rainwater will always have a direct pathway off the roof with this strategy. If cutouts were in a perfectly vertical line, torrents of water would flow like a stream down the rooftop. Excessive weathering would occur in these locations, so contractors make it a priority to alternate shingle locations for long term functionality and attractive appearances.
Shingles at the eave shouldn't be even with the edge. In fact, an overhang of about three quarters of an inch is common. As rain flows off the roof, it could easily stream into the wood roof deck if shingles simply ended perfectly with the edge. This overhang forces water away from the roof and into gutters.
Although shingled roofs are traffic bearing, allow only professionals to walk on the surface. A new installation usually has a limited warranty attributed to it, requiring homeowners to only hire professionals for servicing to keep the legal coverage intact. Contract with professionals and schedule at least two yearly appointments to maintain that warranty. It could save a homeowner significant money if an issue arises.
