NAILING THE UNDERLAYMENT


 

There has always been a lot of controversy in the construction industry on how to properly nail the underlayment or whether it's even necessary. Some roofers use regular roofing nails, some use staples, some attach it with hardly any nails at all, using only a single nail every few feet. It's not that roofers are trying to rip anyone off, they just don't see the need for nailing the underlayment so heavily since the shingles do such a fine job of securing the underlayment.

RoofHelp, and all other professional roofing organizations, consider properly nailed underlayment to be an important part of the roof assembly. It acts a secondary waterproofing element plus it provides longevity for the roof system, click HERE for a brief explanation. There have been several occasions where shingles have blown off in heavy thunderstorms or hurricanes but because the felt underlayment was nailed securely, the damage to the interior of the building was minimized.

RoofHelp has two ways of nailing the felt - one for high wind regions and one for all other regions. If you often experience winds of 50 mph or more, you should seriously consider the high wind method of nailing.
