Roof Deck Attachments

Poorly attached roof decking is a major cause of home damage from hurricanes.

Roof Deck Attachments for Florida Homes

When experts looked at storm damage in major hurricanes, they found that the cause was often poorly attached roof decking. The roof decking is the wood surface, usually made of plywood, that the roof covering is attached to. The way that the roof decking is attached to the framing of the structure is called the roof deck attachment.

The roof deck holds the whole house together, providing structural integrity.

Most roofs in Florida consist of shingles nailed to plywood sheets. If the plywood sheets are not adequately nailed to your roof trusses, additional nails, and/or longer nails, should be added to ensure the plywood is not blown off in a hurricane. If a roof has already been installed, a system such as foam adhesive can be added to increase the uplift resistance of the roof deck and qualify for a mitigation discount. A roof deck that is strong enough to resist hurricane winds protects furnishings and interior walls from rain damage.

Retrofitting makes the roof deck far less likely to separate from the rafters below. If the roof covering is not being replaced, adding a foam adhesive from the attic can create the strong bond between the decking and the framing. This process can be used to increase the uplift resistance of the roof. When the roof is being replaced, the roof deck attachment can be improved by adding additional nails.

Whichever solution is necessary, strengthening the connection between roof deck and rafters will result in annual savings on insurance premiums as well as greater safety and security for your family.
