What Is a Wind Mitigation Inspection?

What is a Wind Mitigation inspection and should I get one?

Wind Mitigation inspection must be performed by a licensed general contractor, building contractor, architect, engineer, building inspector or home inspector. The form used as of August 2014 is OIR-B1-1802 and photos must accompany the wind mitigation report for it to be valid.

Wind Mitigation credits were mandated by the Florida Legislature several years ago, and they earn premium discounts for construction methods within your roof that resist damage by wind. There are several categories of credits, and within the several categories there are several levels of discounts. The age of the home and roof will be examined and inspectors will also be noting and taking photos of the roof deck attachment, roof to wall connection, roof shape and the existence of a secondary water resistance barrier.

The cost of a Wind Mitigation Inspection varies by vendor, but it is generally inexpensive. Do your research on inspection companies. You want to make sure the inspection is done properly. If you need a referral we work closely with and trust a few local inspectors so just ask!

The only way to know exactly how much you can save is by having the inspection done. The inspection cannot hurt you or cause your premium to go up. It can only cause the premium to stay the same or go down, sometimes by several hundreds of dollars!

Understanding a Wind Mitigation inspection

Understanding A Wind Mitigation Inspection

You definitely don’t have to be a professional to understand a Wind Mitigation inspection, however it does get technical.  Let’s take a look at what the inspector is looking for, why he or she is looking, and how the process came to be.  

First, it’s important to know that the Uniform Mitigation Verification Inspection Form is actually a legal affidavit.  That means that it’s considered a written statement confirmed by oath or affirmation for use as evidence in court.  This goes along with why all insurance companies in Florida must offer premium discounts for Wind Mitigation (although they can vary by company); the state legislature mandated the credits!

A Wind Mitigation Inspection looks at 7 areas of your roof system.  They are:

1. Which set of building codes is your entire home in compliance with?  Basically, when your house was constructed determines how strict the building codes were and how wind resistive it is at a minimum.
   • Wind Mitigation Discount Tip:  The newer the home the deeper the discount.  
2. What kind of roof covering you have.  This is where the inspector notes if you have shingles, tiles, etc., and what building codes they are compliant with.  This is important because an older home from the first item can have a much newer roof.
   • Wind Mitigation Discount Tip: The newer the roof the deeper the discount (much more so than in number 1)
3. What is the weakest portion of your roof decking (typically the flat plywood under roof) made of, what kind of nails is secured down with and how far apart are the nails.
   • Wind Mitigation Discount Tip:  Plywood is almost universally used, but not always.  The longer the nails and the closer they are together, the deeper the discount.  
4. What is the roof attached to the walls of your home with?  There are 8 findings the inspection can have, but the most common in order from weakest to strongest are Toe Nails, Clips, Single Wraps, and Double Wraps.
   • Wind Mitigation Discount Tip:  If you are re-roofing your home make sure the best/strongest method is used.  All you have to do is upgrade as much is possible.  Always ensure proper permits are pulled and building codes are followed too.
5. What is the geometry of your roof?  Very simply put, from a home insurance perspective, hip roofs are the best, gables are OK, and flat roofs are great for wind but aren’t so great overall.  A hip roof slants up on all sides like a pyramid.  It can have more than 4 sides.  Hip roofs can withstand the highest pressure loads from very fast blowing wind.  Gable roofs can be simple upside down V-shaped roofs or roofs with multiple peaks in the shape of a letter V.  Gable roofs can only withstand certain pressure loads because the blowing wind can get under and lift them, unlike hip roofs.  Flat roofs are less of a wind issue, but they tend to collect debris and to be very leak prone as they age.  
   • Wind Mitigation Discount Tip:  If building or purchasing a home, a hip roof is always preferable.  A home with a hip roof will generally have a lower insurance premium than a perfectly equivalent home with a gable or flat roof.
6. The first item that has absolutely nothing to do with wind but is on a Wind Mitigation Inspection is Secondary Water Resistance.  Does the roof have more than just felt paper between the outer covering (shingles/tiles/etc.) and the decking (plywood)?  Is there rolled waterproof membrane in between?  Felt paper has a tendency to dry out and behave like potato chips.  As it crumbs away water can permeate the wood decking and work its way into the house causing damage.  Secondary Water Resistance helps prevent this water intrusion.
   • Wind Mitigation Discount Tip:  On a re-roof make sure Secondary Water Resistance is used.  It’s now part of the building codes throughout Florida to use it on new construction.
7. Opening Protection is another less roof involving item, but it very much concerns itself with wind.  This possible credits looks to see if your house has hurricane shutters, specially designed garage doors, windows, skylights or other “openings” meant to withstand wind and strikes from blowing debris.  
   • Wind Mitigation Discount Tip:  A few extra bucks on the hurricane rated garage door/skylight/windows/etc. and investing in hurricane shutters will qualify you for some extra discounts!

Who Executes a Wind Mitigation inspection?

There are 6 types of qualified people who can sign-off on your Wind Mitigation Inspection.  It must also include your signature a series of photos that substantiate each of the 7 items.  Sadly, the photos became a requirement because a lot of Wind Mitigation fraud when the program first came to be.  This six approved inspectors are:

1. A Home Inspector licensed under Section 468.8314, Florida Statutes, and is properly trained and passes a test, such as  interNACHI certification.
2. A Building Code Inspector certified under Section 468.607, Florida Statutes.
3. A General, Building or Residential Contractor licensed under Section 489.111, Florida Statutes.
4. A Professional Engineer licensed under Section 471.015, Florida Statutes.
5. A Professional Architect licensed under Section 481.213, Florida Statutes.
6. Any other individual or entity recognized by the insurer as possessing the necessary qualifications to properly complete a uniform mitigation verification form pursuant to Section 627.711(2), FL Statutes.
   • Item 6 is rarely used – I’ve never seen it – and is solely at the discretion of your insurance company.  Insureds – you – have no say in the matter regarding the acceptability of a Wind Mitigation Inspector outside of the first five legally defined types.

Where did Wind Mitigation credits come from?  

Building Inspector

Every home insurance company in Florida must offer Wind Mitigation discounts.  However, there is no standard amount for each of the 7 credit earning items, nor is there any scientific data used to determine how much credit each carrier awards for each item.  Insurer A might give a 5% discount for having “Clips” in item 4, but Insurer B might offer only 1% or as much as 10%.  These discounts are also often only applied to the “Wind” portion of your premium:  Say your insurance costs $1,000.00 per year.  It is then broken down into “Wind” and “Non-Wind” portions.  Again, there is no standard amongst carriers for that split, so there is no way to substantiate it on a common level for all homeowners.  Effectively, the Florida Legislature said, “In order to get reelected we need a juicy talking point about saving Florida homeowners money on their insurance.  We’re going to cast aside the scientific data that makes claims costs predictable and require quasi-scientific discounts.”   

The proof is in the pudding.  It’s why the companies are required to offer a certain level discount.  There’s no data to use to be certain that feature X is really that significantly better than feature Y.  Thus, the elected officials get to say they got you a discount, but the insurers get to make it as big or little as they want because it’s not really a science-based item.  

This doesn’t mean that all Florida homeowners shouldn’t take advantage of a Wind Mitigation Inspection.  We often find that the inspections pay for themselves, earning at least $80-$100 of credit each year for a guaranteed 5 years (often longer).  Many times the credits reach well into the hundreds and even thousands of dollars.  It is rare that no credits are earned because without the inspection your home is assumed to have the least possible wind resistive features.  It’s also important to note that the inspection CANNOT hurt you.  You cannot be charged more unless you had a prior Wind Mitigation Inspection that had incorrect findings in your favor.  I urge all Florida homeowners to get the inspection done.  I cannot guarantee a savings with 100% certainty, but it’s tremendously likely ( 90% or more in my opinion) that you’ll wind up with a positive result!
