Norwalk Roofing: Article About Roof Ridge Shingling Strategies
Homeowners see the intricate patterns shingles make on rooftops as they rise to meet the peak or ridge. This topmost meeting point is one of the most vulnerable areas on a rooftop because it's exposed to all weather events, from rain to hail. When Norwalk roofing professionals repair or replace roofing components, they must service the ridge with specific material placement procedures. Without proper protocols, ridges become pathways for frequent leaks.
Servicing ridges with care requires the right materials. Roofers have two main choices for ridge coverings: cut shingles or ridge caps. When contractors have ample shingles at a job site, they can cut the tabs to form rectangular pieces. They use these pieces to cover the ridge, which contributes to a streamlined appearance across all shingled surfaces. Ridge caps are specially designed covers that conform to the peak's shape. Many contractors are turning to these material solutions instead of cutting shingles to size.
Before contractors apply their specific ridge covering, the roof must have its basic shingles properly attached. The final shingle course at the ridge should be flush against the slope's edge. There cannot be any exposed decking within this area because leaks can easily saturate materials. The last shingle course works in conjunction with the ridge covering to direct water down the roof and into gutters.

Fastening ridge coverings is entirely different than other shingled areas. With the material straddling the ridge, contractors add one nail to each side. The longer lengths must have nails five inches above the edge while shorter end pieces only require one inch spacing from the edge. This nailing technique reduces wind uplift damages, holding the materials squarely to the structure.
Homeowners may be familiar with ridges displaying a stacked material effect, but this technique isn't the best choice for modern products. Today's ridges are capped with shingles that are layered only at adjoining edges. This installation choice is meant to cover nails and prevent excessive weathering. Roofers may even use some roofing cement to further protect fasteners while contributing to an attractive aesthetic.
When contractors must remove and replace roofing materials at the ridge, they have a chance to see part of the substrate or decking. This base roof layer is difficult to examine unless the roof is being serviced with a tear off and replacement process. Although roofers only see a small decking area at the ridge, any clues to leaks or structural decay help workers service the property better over the years.
