Nails for wooden chimney chase metal “top hat”
as could a 45 mph wind which would blow the top had off and soak my house and living room side. they fixed it but I dont know how well.
So I thought about that when Dorian went through .
how many fastners do I need and should they be screws or nails and with what size heads, A top hat could easily see 100 to 140 mph wind- seems you would need more than a regular small nail head- that could pull thru the galvalume metal?
what say you Finehomebuilding brain trust- screws? nails? washers? how many on each side? Thanks . would an architcct specify?
now it seems to have 2 nails , together, at end of each side, so 4 nails on the long side, but no fastners anywhere else, that is, none in the middle of the 6 ft long sides. and looks from the ground like 6 penny common nails (small heads.)
I would use SS screws rather than nails. No one has ever complained that they had too many fasteners in anything after a hurricane. I'd put 6 on each side and 2 or 3 on each end.
and I guess I need the type screws with the washer as part of the head?
this subject I cant find anything on, on the web.
if anyone knows where more info might be, please direct me
Waferhead screws, come in stainless and self drilling through metal.
In florida does Miami Dade have any requirements on this? seems like the hurricane winds would increase the need for more nailing, nails or screws?
