Wind Mit Form SWR Section

[Gary Young]

With the typical Florida Clay Tile roof, do the insurance companies want proof of a Self adhering polymer modified bitumen roofing or is it a given?

[Thomas P. Korte]

Documented proof!

[Michael J. Meeker]

Not ever a given.

Good luck finding them applied as necessary or my opinion of necessary in S. Florida.

Fortunately, at the conference last weekend, this was addressed.
You will need the permit or the invoice with the phrase "peel and stick membrane", than manufacturers name and...I forgot, but something else. Maybe Michelle will chime in and post the third thing.

The client may have to contact the roofer to get the information. You can also try to get a picture of the membrane in between the two pieces of plywood and send that with the report.

Added with edit:

For SWR you need:

The roofers invoice that lists Peel & Stick Modified Bitumen SWR

The Manufacturer of the Product

The Brand Name

You are wrong.

I am getting one from one of my customers as we speak. The documentation is available. Take the extra step and ask for it.

[Michael J. Meeker]

I do ask and am not wrong I just have almost never given that credit. Maybe twice.

Submit that with the report. I just went through this with a client and he got the credit as he sent the invoice that had the above information to his insurance company.

If everyone followed the building code, there would be no problems.

Permits required

[John Shishilla]

You do not need an SWR to meet code. SFBC does not allow it to be applied as required to meet SWR on the 1802.

Then again, actually still, the form is incorrect, or at least the way it is interpreted, isn't it?

And, my reply was to the permit portion of the statement. The first thing that has to be done for any work that requires a permit is................................................ ..........



wait for it................................................ .........


Apply for the permit!

1. In either HVHZ or non-HVHZ regions,
a) All joints in structural panel roof sheathing or decking shall be covered with a minimum 4-inch (102 mm) wide strip of self-adhering polymer modified bitumen tape applied directly to the sheathing or decking.
The deck and self adhering polymer modified bitumen tape shall be covered with one of the underlayment systems approved for the particular roof covering to be applied to the roof.

b) The entire roof deck shall be covered with an approved asphalt impregnated 30# felt underlayment or approved synthetic underlayment installed with nails and tin-tabs in accordance with Section R4402.7.2, R4402.7.3 or R4402.7.4 of the Florida Building Code, Residential.

No additional underlayment shall be required on top of this sheet for new installations.
b) An underlayment system approved for the particular roof covering shall be applied with the following modification:
(1) For roof slopes that require one layer of underlayment, a layer of approved asphalt impregnated ASTM D 226 Type I or Type II underlayment or approved synthetic underlayment shall be installed. The felt is to be fastened with 1-inch (25 mm) round plastic cap or metal cap nails, attached to a nailable deck in a grid pattern of 12 inches (305 mm) staggered between the overlaps, with 6-inch (152 mm) spacing at the overlaps. The synthetic underlayment shall be fastened in accordance with the manufacturer's recommendations.
(2) For roof slopes that require two layers of underlayment, an approved asphalt impregnated ASTM D 226 Type I or Type II underlayment shall be installed in a shingle-fashion and lapped 19 inches (483 mm) and fastened as described above.

Nick, I don't follow the Miami-Dade code revisions but I recall that they had at one point prevented use of mod-bit direct applied to sheathing. Did they change that again?
