What happens if you nail shingles too high?
When the shingle is nailed too high the nail does not penetrate the shingle below it. High nailed roofs are easily blown off in windy or stormy conditions because the roof isn’t “connected” like it should be. Inadequate nailing means big reduction in wind rating.
What is high nailing and what is the issue that can result from it?
Placing nails in the adhesive strip can cause the shingles to fail to seal properly, reducing their wind resistance. Placing fasteners above the adhesive strip, called “high-nailing,” will also reduce the shingle’s wind resistance. On strip shingles, fastener placement should be limited to areas within the green strip.
How many nails do you use when nailing shingles in high wind areas?
six nails
Since then, the International Building Code required roofers to fasten shingles using six nails. You must also properly space nails in front of the seal line. They required these high-wind-rated products on any roofs in wind regions rated at or above 110 mph.
Should roof shingles be stapled or nailed?
Roofing nails are highly preferred to staples for asphalt and other types of roofs because they offer more holding power, meet building codes, and are easier to install correctly.
Can I nail down loose shingles?
Cut pieces with utility knife as necessary to position new pieces. Put roofing cement beneath new shingles to ensure they stick down. Use the holes where you removed the original nails when nailing new shingles. Be sure to nail back down any undamaged shingles that had to be loosened to release damaged shingles.
Should I nail shingles on the tar line?
Because the thickness, weight, and shape of shingles vary, manufacturer’s instructions vary slightly. But virtually all manufacturers agree that nails should be installed below the adhesive strip.
Where should nails be placed in shingles?
Use 4 nails per shingle placed 6-1/8″ above the butt edge, 1″ and 13″ in from each end and 1/2″ above each cutout. Drive nails straight so that nail head is flush with, but not cutting into shingle surface.
Do staples damage shingles?
Staples damage your shingles. Tiny holes from repeated stapling will limit the lifespan of your roof considerably. Asphalt shingles will lose granules much quicker this way, and wooden shingles can splinter and even rot away from underneath if water seeps beneath them.
What do you nail shingles down with?
Galvanized roofing nails tend to resist rust formation, and they are a suitable option for asphalt shingles. Owens Corning requires using either galvanized steel, stainless steel, or aluminum nails to affix shingles.
Where should you nail shingles?
Where do you put the nails on shingles?
Penetration. When nailing shingles, proper penetration into the roof deck is essential to ensure the nail and shingle remain secure. For all Owens Corning® shingles, roofing nails should penetrate into the wood deck by a minimum of ¾-inch or completely through the roof deck by a minimum of 1/8-inch.
