Not all hurricane clips are the same. Some hold 1,000 pounds. Others hold 1,500. The difference between a roof that stays on and one that blows off often comes down to a $3 piece of metal. Here's how to pick the right one.
Each connector type has trade-offs. More strength costs more money and takes more time. Here's how they stack up.
Every clip does the same job: keep the roof attached to the walls when wind tries to lift it off.
During a hurricane, wind flows over your roof like air over an airplane wing. This creates suction that pulls the roof upward. A typical roof can experience over 1,000 lbs of uplift force per truss.
Hurricane clips wrap around the truss and nail into the wall plate below. They create a continuous connection from roof to wall. When wind lifts, the clip pulls against the wall instead of just the nails.
Double-wrap clips contact more wood. More nail holes means more nails. Straps that go over the top engage both sides of the truss. Each design choice adds strength but also cost and install time.
Figure out how many clips you need and what it'll cost.
The H2.5A clip wraps around the truss from one side and provides about 1,000 lbs of uplift resistance. The H10 clip wraps around from both sides and provides about 1,340 lbs of uplift resistance. H10 is stronger but costs more and takes longer to install.
Standard toe-nails handle only 200-400 lbs. Single-wrap clips like H2.5A handle about 1,000 lbs. Double-wrap clips like H10 handle about 1,340 lbs. Hurricane straps can handle 1,500+ lbs depending on the model.
Yes. Broward County is in the High-Velocity Hurricane Zone (HVHZ) where building code requires approved roof-to-wall connectors. Toe-nails alone do not meet code for new construction or re-roofing projects.
Yes, retrofit hurricane clips can be added from the attic. This is one of the most cost-effective hurricane upgrades. Many insurance companies offer discounts for verified hurricane clip installation.
It depends on the clip type. H2.5A clips typically need 4 nails (2 in truss, 2 in wall plate). H10 clips need 6-8 nails. Using fewer nails than specified dramatically reduces the clip's strength.
