New 1802 (Rev. 04/26): quick answers to the questions that keep coming up

A few things from the threads here that keep tripping people on the new 1802:

Q2, wind speed. The form says ASCE 7-22 (700-year MRI), Risk Category 2, with the hazard tool at ascehazardtool.org. If you get 134 mph on one setting and 144 on another, check which Risk Category you selected. A normal single-family home is Category II. All of Miami-Dade and Broward are HVHZ.

Q3, roof slope. For a roof with several slopes, the form says to use the slope that covers at least two thirds of the main roof area, and to answer whether it is 6:12 or steeper. Measure it while you are on site; you can’t go back to get it from the car.

Q8, sealed roof deck (SWR). Option A on the new form now includes a double layer of felt or synthetic with no tape (two layers of ASTM D226 Type II, D4869 Type III/IV or D8257), along with fully adhered underlayment, taped seams and spray foam. Standard underlayment or hot-mopped felts still do not qualify. If you can’t verify which method it is, C (Unknown or undetermined) is a real answer on the form. Back it up with photos, a permit or a Fortified certificate where you can.

Disclosure: I build Warrior Inspection Network, a Florida-only tool for wind mits, 4-points and roof certs that fills in the state’s own form pages. Questions about the form are welcome whether or not you ever use it.

Notes like these save a ton of back-and-forth. The Risk Category II reminder looks especially handy.
