Florida property insurance premiums are among the highest in the nation, and for many rental property portfolios, wind coverage represents the largest share of that cost. A wind mitigation inspection is one of the few levers property managers can pull to meaningfully reduce those premiums -- not by reducing coverage, but by documenting the physical features of a property that make it more resistant to wind damage.
Premium reductions from a favorable wind mitigation inspection typically range from 10 to 40 percent of the wind portion of the premium. For a Florida coastal property paying $8,000 per year for wind coverage, that is $800 to $3,200 in annual savings from a single $100 inspection.
What a Wind Mitigation Inspection Assesses
The OIR-B1-1802 form documents six construction features that Florida insurance companies use to calculate wind mitigation credits. Each feature is rated on a scale from least to most wind-resistant, and the combination of ratings determines the total discount available on the policy.
Roof Shape
Roof shape is one of the most significant factors in wind resistance. Hip roofs -- where all four sides slope downward to the walls -- perform significantly better in high-wind events than gable roofs, which have vertical triangular ends that are more vulnerable to wind uplift. A fully hip roof qualifies for the highest credits. Properties with partial hip configurations receive partial credit.
Roof Covering
The inspection documents whether the existing roof covering meets the Florida Building Code or Miami-Dade Product Approval standards -- the highest level of wind resistance. Metal roofing systems and concrete tile installed to current FBC standards generally qualify for the highest credits. Older asphalt shingle installations that predate current code standards receive lower credits.
Roof Deck Attachment
The roof deck is the structural sheathing nailed to the roof framing. Inspectors assess nail size (6d vs. 8d), nail spacing, and whether clips or staples were used. Properties built or re-roofed under current Florida Building Code typically qualify for favorable ratings. Older properties with staple-attached or lightly nailed decks receive lower credits and represent the greatest vulnerability in a wind event.
Roof-to-Wall Connection
The inspector documents the type of connector: toe nails (least resistant), clips, single wraps, double wraps, or structural connectors (most resistant). Modern Florida construction requires hurricane straps or clips. Older construction -- particularly pre-1994 properties in South Florida and pre-2002 properties elsewhere -- often has only toe-nail connections, which receive no credit.
Secondary Water Resistance
Secondary water resistance (SWR) refers to a self-adhering polymer-modified bitumen layer applied to the roof deck before the primary roofing material is installed. If the primary roofing fails in a storm, SWR provides a secondary barrier against water intrusion. Properties built after 2008 in most counties have SWR as a code requirement. Properties with documented SWR receive significant credits.
Opening Protection
How well a property protects its openings -- windows, doors, skylights, and garage doors -- is one of the most controllable factors. The inspector documents the type of protection: no protection, basic wind resistance, impact-resistant glass or panels, or Miami-Dade HVHZ approval. Full opening protection with HVHZ-approved systems provides the maximum credit and is the single highest-ROI upgrade most Florida property managers can make to existing buildings.
How Credits Work on Citizens and Private Policies
Florida law requires all admitted carriers to offer actuarially justified credits based on the OIR-B1-1802 inspection results. Citizens Property Insurance publishes its wind mitigation credit schedule publicly. Private carriers calculate credits differently, which is why the same property can receive different discounts from different insurers.
The credits are applied to the wind portion of the premium -- not the total premium. Since wind coverage typically represents 50 to 80 percent of a Florida coastal premium, a 30 percent wind credit translates to roughly 15 to 24 percent of total premium reduction.
Typical Premium Reductions
Based on the Citizens credit schedule and typical private market credits:
- Hip roof: 10 to 20 percent credit on wind premium
- Secondary water resistance: 5 to 10 percent credit
- Roof deck -- 8d nails, 6/6 pattern: 10 to 15 percent credit
- Double-wrap roof-to-wall connectors: 10 to 15 percent credit
- Full HVHZ-rated opening protection: 20 to 30 percent credit
These credits can stack, but most carriers cap total wind mitigation credits. A well-built post-2000 Florida coastal property with hip roof, secondary water resistance, hurricane straps, and impact windows can qualify for the maximum available credits -- sometimes 40 percent or more of the wind premium.
The 5-Year Re-Inspection Cycle
Wind mitigation inspection reports are valid for five years. At the five-year mark, the report expires and the carrier can no longer apply credits without a new inspection. Property managers should track inspection dates and schedule re-inspections 60 to 90 days before expiration to avoid losing credits at renewal.
Re-inspections are also warranted any time significant roof work is completed -- a full re-roof, re-decking, or opening protection upgrade. These improvements may qualify for higher credits than the previous inspection documented.
When a wind mitigation report expires, the carrier is no longer required to apply the credits -- and many will not unless a new report is submitted. An expired inspection is the same as no inspection for premium calculation purposes. Portfolio managers who are not tracking inspection expiration dates are likely losing credits they earned years ago.
Using the Report When Shopping for Coverage
A wind mitigation report is portable. When a property is re-shopped to new carriers at renewal, submitting the OIR-B1-1802 form ensures that each carrier applies the appropriate credits. Without the form, some carriers quote without credits and some apply assumed credits -- making it impossible to do a true apples-to-apples comparison.
Order wind mitigation inspections 60 to 90 days before policy renewal for each property. Submit the OIR-B1-1802 form with your renewal request and also use it when shopping for alternative quotes. Carriers are required to apply the credits -- getting the inspection done before renewal shopping ensures every quote reflects the same discounts.

Start Free -- No Card Required ->The Bottom Line
Wind mitigation inspections are one of the highest-ROI actions available to Florida property managers. A $100 inspection that generates $1,500 in annual premium savings pays for itself every year. The key is maintaining current reports across the portfolio, scheduling re-inspections before the five-year expiration, and submitting reports every time a property is shopped for coverage.
