Can someone tell me if the total building perimeter is included in the roof geometry for a townhouse or just the unit being inspected for the windmitgation. The reason I ask one unit maybe considered a hip but the other unit would be a gable. If I add them together it would all be a gable
Thank you in advance
You cannot use the sum of gables on one unit only divided by the entire roof perimeter. You should use the sum of all gables devided by the total roof perimeter - IMHO ---- However, that might depend on how the roof geometry lays out. Does it appear that each unit has its own well defined roof that is not tied into the other units? If it does, then you would use onlly the gables and roof perimeter which applies to that unit. Most townhomes that i have seen share a common roof which is seperated only by firewalls in the attic. the fire walls are normally not structural in nature, therefore if part of the roof was to blow off over one unit, the other units would most likely be adversely affected — that is why i say – total of all gables over the total of entire roof perimeter. Others may disagree
No offense to anyone here but that makes me think.
You know what I think is funny?
Many feel that a square house with gable ends on two opposing sides is half hip and half gable. :roll:
Guess what?
It is a gable roof. 
Total building perimeter, like a big house… Unless, the firewalls extend above the roof line seperating the units. Most likely, you treat it like a big house
I hope noone got that one wrong.
Now for a hard one: square house with hip on three sides and gable on one side - Mike, you go first
PS — ok a hint — the gable is in the front and is the side to the right (and left) of a hip — lol
My opinion is gable.
If it is a square than the front would be 25%. 
I think the form should read Hip or Not.
That would be plain and simple.
That makes the most sense to me
I’m glad I don’t live in Florida 
Instead of everyone guessing, why not contact the insurance company and let them explain how it is supposed to be done.
Haaa haaa haaa. Good one Bill 
Even better yet, why not ask the people who made the form? The OIR.
Mike,
You are not dealing with logic here. Everybody has a different answer. The fact of the matter is - it is not up to us to decide how it should be done. Get the answer from the horses mouth, put a note in the report that so and so from such and such a company said to to it this way. Understand that the next person you talk to may say something different. At least this way you have a name to go back on.
Im not guessing
Dennis,
Qualify that statement please
That doesnt make sense to you Bill?
I am all for it the only problem is every insurance company and every insurance guy will have a different answer.
I would just like the Oir to make some concrete decisions on what=what in plain English and then I will gladly report on the conditions as I find them.
Hmmmm - Thats pretty clear to me
Dennis B. did not GUESS at the way he said it should be done. It IS the right way.
Dennis B is correct
Dennis
I like your answer and agree regarding the whole building unless the fire walls protrude.
Think of this “are we to determine if the fire walls are structural”? In a high wind event that knocks down all the trusses and the trusses take down the firewall then the unit is compromised!
Just being a little :twisted: -----
