Greg- that's a building code requirement specifically for slate? Composition/asphalt shingles are just two inches headlap(per manufacturer) all the way down to 4/12? Sounds odd to me but, gee, isn't it nice to actually get "slate recognition" from city hall, if true. North Carolina is kind of a "buzzword" for me over here at 28425 outside Wilmington- look me up in the consultants section and RSVP if you might like someone like me to look over your shoulder once't or twice't... | ||

Greg, Looks like your on your way to a really good looking roof, you should post some picture for all to see, progress or finshed pictures. | ||

I am planning on using the 2 nail standard method for applying the old slate. I just thought I would need some slate hooks to replace slates that were intentionally left out for roof jacks, etc. I understand the nail and bib technique now--thanks for the link Joe. As for the reason I am using 4" headlap, I am doing a 7 in 12 pitch, fairly flat for a slate roof. Also, there are heavy lap marks on the 80 year old 22" X 14" buckingham slate (which previously used a 3" headlap) that I am trying to conceal. And most importantly, our building code here in North Carolina requires a 4" headlap for anything flatter than 8 in 12 pitch. Is this an odd code requirement? Thanks for your input, Greg | ||

Greg, Why are you using a 4" headlap to begin with ?? | ||

Greg- i agree with William, nail your roof as per custom- the European all-hook roofs may be of a different layout to save slate/weight and the hooks therefor are advised. Further for the nail and bib, also called the "baby" or "babie"?- if you're gonna knock a hole in a slate, why do it out in the weather part of the shingle and have to cover it w/ a bib? All that takes longer and costs more than a hook and you ruin that slate w/ the hole or destroy it(maybe) if you punch it "in situ"- punching the top inch of a slate(4" exp.) leaves three(3) inches of weather protection for that hole automatically and I wouldn't call it a "ruined" slate, either- small nailsets and icepicks, etc. are great for easing holes in slates esp. if you support the slate while punching and then put it back into the roof when done- the icepick makes good scratch marks to go by for that process... make your own 4" hooks? The strap and nail method isn't long-cycle technique for slate but it will work- subject to ice damage and rusting, etc. | ||

Sorry Bill, in Europe they install whole roofs with hooks and they look great. Stainless steel hooks are not likely to rust. Maybe they are using slate hooks in the areas where they have omit a slate to install roof brackets... For an illustration of the nail and bib method check out the info section on this site. There's a guide somewhere. | ||

you say you are putting a salvaged slate roof on your new house??? why are you hooking it??? if you are doing a new install with old stuff you should only have to nail it just as you would any new install, hooks will always eventualy rust out and they look like crab on an entire roof. leave the hooks for repairs..

I guess I'm unfamiliar with the nail and bib technique. Is this a bib bent at the bottom to act as a hook to hold the slate? Thanks again, Greg | ||

If it's more than 3" you would have to drill or punch through the slate which is not the best idea. You could always use nail & bib instead. | ||

I'm getting ready to put a salvaged slate roof on my new house. My question is this: Do the standard slate hooks (like the ones sold here) work if the headlap is 4 inches instead of three? It seems like these are too short to drive into the subroof without hitting the course underneath if the headlap is greater than 3 inches. Any clarification is appreciated. Thanks, Greg |
