How Many Nails....


do you use per shingle? I have worked for people who want only 4 and some who demanded 5. My personal standard is 5, however I don't hold it against anyone who only uses 4. and I 6 nail anything on a 12/12 or higher.

I think you wrote the book on nails per shingle!

Re: How Many Nails....


When we ran nail guns we 6 nailed every thing from a 9/12 and up,
4 is plenty when hand nailing until you get to a mansard, than double nailing should be done, atleast in my opinion.

Re: How Many Nails....


isnt there actually a nailing pattern
too many nails can put you closer to ''key way'' than you should be no?

with 3 tabs I only 4 nail to avoid this, except on a steep slope I'd 6 nail them 1 at each end and 1 on either side of each key-way, with dimensional shingles, It's a matter of how far you step them. and 6 nails is what Certainteed calls for on steep slope application.

Re: How Many Nails....


Yes, Tom is right. There is a nailing pattern. You don't want a nail on a shingle right below a joint. We do 4 per shingle. Use more in windy areas or wind traps with valleys and surrounding buildings.
Nail placement is more important than how many.

Re: How Many Nails....


I agree with 5 or 6 nailing on a real steep slope, but whenever we see a roof 6 nailed, we usually figure a farmer did the roof. They did this in the past to keep shingles on with many layers and shingles with no tar strip.

Re: How Many Nails....


Wow
Most of the roofs around here are 3 nailed, the stupid part its the tar strip that usualy fails and makes the loved "flapper"


I screw the piss out of my roofs so Im as bad as you 6 nail guys i suppose, I hate callbacks and have yet to have 1 for a roof.......roofjacks are my nemesis after heavy snows break the pipes off

Re: How Many Nails....


Hello,

It depends on where you are located. When I lived in Va. we only 4 nailed unless it was steep. Here in AK every roof is 6 nailed. We have winds of 25+mph quite often so it just becomes a habit.
Most important though is what the manufacturer calls for(imo). Follow that and you should be o.k.

Oh, btw even though I am from the country I am not a farmer. LOL

I don't care if you put 20 in each shingle, if that tar strip does not seal to the next shingle, it's coming off.

Re: How Many Nails....


Self sealer strips are not designed to hold shingles on the roof, the fasteners do that. The sealant strips hold the tabbed or lower laminated portion in place.
I have lost a few tabs here in there on jobs that are prone to high winds, etc., but never lost a shingle.
If you see a roof with missing tabs, maybe it's a self sealer issue, maybe it's a fastener issue, but if you see shingles missing it's a fastener issue period.
