After hearing about difficult yard clean ups following a roof installation, customers often ask us, “Are roofing nails magnetic?” Well the answer is, it depends on which type of nail is used. Some common roofing nail materials include:
- Stainless steel
- Galvanized steel
there are many methods used to galvanize nails, but all coat the nail in order to protect it from corrosion. While stainless and galvanized steel nails are magnetic, aluminum and copper nails are not.
Why does it matter whether they’re magnetic?
Thousands of nails are used in each roof. During the process of tearing up an old roof or installing a new one, a responsible contractor such as Midwestern Construction will lay down tarps to catch loose nails. In order to retrieve any remaining nails from the surrounding lawns, roofing magnets are used and the task is completed quickly and easily.
Aluminum and copper nails require a much more labor intensive clean up. Whether using a metal detector or simply crawling and spotting nails up close, it will take much longer to get the job done. Make sure not to mow until you get the nails out of the grass, as nails become shrapnel when shot out by a mower blade. Avoid injuries to people and property holding off on mowing.
Why not only use magnetic roofing nails?
Every type of nail has their purpose, and a good roofer with take all factors into consideration before choosing which nail to use. For roofs near the ocean, an aluminum nail might be best to resist the corrosion from salty air. Similarly in urban areas where sulfur acids in the air might damage galvanized coatings an alternate may be necessary. On the other hand, certain roofs such as slate require copper nails.
Be sure to ask your roofer which nails they plan on using and how they intend to ensure a safe yard free of nails after they complete the job. A professional roofing company will be pleased to answer the following questions:
- Are roofing nails magnetic?
- Which nails are best in your area?
- Which nails are recommended for your roof type?
- Are there,any guarantees about clean up?
Getting a roof installed is a major purchase, and you have every right to know how your roofer will complete the job safely. With quality materials and installation a roof will serve you well for many years to come.
