Strong winds are one of the greatest sources of wear and tear to any roofing system. Uplifting breezes can cause poorly fastened shingles to become free of their nails, allowing them to blow off. This creates the opportunity for water to infiltrate the bare spots created by missing shingles. Even straight-line winds are a problem for roofing systems, as they can cause shingles to curl, crack or split. Experienced Syracuse roofing experts use different techniques in order to strengthen rooftops against the effects of damaging winds.

Most asphalt and composite shingles are nailed to the roof with long, thick nails. A typical nailing pattern involves the use of four nails. One easy way that roofing crews can enhance the roof's strength is to use six nails. When the fasteners are spaced closely together, this reduces the ability of wind to blow off one or more of the shingles. The cost of installing six nails per shingle is minimal, as roofing nails are inexpensive. Because the roofers use nailing guns, the additional time required for their installation is also minimal.

Roofers often use the tar line as a way to guide the positioning of nails, regardless of how many fasteners are used on the roof. Most manufacturers specify that the nails be located between 5.5 and 6 inches above the bottom of the shingle's edge and underneath the seal down strip. However, the size of the shingle and the actual placement of the sealing strip can vary. The roofers will place the nails as close to the newly installed shingle and the course below it as possible. This helps to make sure the shingles are correctly overlapping one another and adds to the roof's structural integrity.

Houses with a steeply pitched roof may require even more shingles, especially when they are located in windy areas. A roof with a slope of greater than or equal to 9 to 12 is considered steep. Roofers will place two nails around the middle tabs or cutouts of the shingles on steeply sloped roofs as opposed to the one nail that is usually used on moderately sloped roofs.

Another technique for ensuring shingle strength in high wind areas is to only install a new roof when the weather is warm enough for the sealing strips to self-activate. In northern locations, this means only installing roofs from May through October, when the sun's energy can heat up the shingles enough to activate the asphalt and adhesives.
