Tampa Wind Mitigation Inspection Guide: Form OIR-B1-1802 & Insurance Credits

Florida homeowners pay some of the highest property insurance premiums in the nation, but state law (F.S. 627.711) requires insurance companies to offer substantial discounts for certified wind-mitigation construction features. Conducting a professional wind mitigation inspection (Form OIR-B1-1802) after a new roof installation or as an independent evaluation can save Tampa homeowners hundreds to thousands of dollars every year on their insurance premiums.

Seven Key Wind Mitigation Features That Maximize Premium Credits

A licensed inspector evaluates seven specific architectural and construction parameters. Among these, roof covering age, roof deck attachment nail size and spacing, roof-to-wall connectors, and secondary water barriers deliver the largest insurance discount credits in Hillsborough County.

  • Roof Covering: Verifying installation under 2001 or newer Florida Building Code
  • Roof Deck Attachment: Level C credits for 8d nails spaced at 6 inches along panel edges
  • Roof-to-Wall Connection: Clips or single/double wraps securing trusses to wall plates
  • Roof Geometry: Hip roof shapes qualifying for up to 40% base premium wind discounts

Secondary Water Resistance (SWR) & Self-Adhering Underlayment

Secondary Water Resistance (SWR) is a self-adhering polymer-modified bitumen underlayment applied directly to the bare wood roof deck. If hurricane winds strip outer shingles or tiles, the SWR membrane seals around fastener penetrations and prevents interior water inundation, qualifying your home for top-tier wind mitigation credits.

  • Peel-and-stick membranes sealed across 100% of the roof sheathing surface
  • Self-healing properties around mechanical fasteners preventing nail-hole leaks
  • Photographic documentation of SWR membrane during dry-in for inspector sign-off
  • Substantial reductions in water damage risk and corresponding insurer loss exposure

Frequently asked questions

How long is a Florida Wind Mitigation Inspection report valid?

A completed and certified Form OIR-B1-1802 wind mitigation inspection report is valid for five years from the inspection date, after which a re-inspection is required to continue receiving insurance premium credits.

Can hurricane clips be retrofitted to an existing home in Tampa?

Yes. If your home was built with simple toe-nails, specialized wind mitigation retrofit contractors can access the attic space or exterior soffits to install engineered hurricane clips, qualifying your home for major insurance discounts.
