The headlap is fine. The underlayment laid on top of the slates is a mistake which now creates a maintenance nuisance until it eventually turns to dust. | ||

You have a 3" headlap then- you're all set there. | ||

Slates are Vermont Gray. 14 X 20 with 8.5" of exposed face. The pitch is 8:12. | ||

Can you find out the headlap, or slate size and exposure, and the slope of the roof? | ||

The roof is original to the house 1947. From what I have read they installed felt to slightly decrease the amount of slate needed on the roof. I have read about this technique in several places. I have not measured the headlap but it appears to be enough to have lasted all these years without leaking. | ||

When was the roof installed and why was underlayment installed between the courses? What is the headlap? You may have a much bigger problem there than is immediately apparent. If there is no or little headlap and the felt paper is what's keeping the roof from leaking, the entire roof will have to be removed and re-installed correctly. | ||

Retrofit guards like you're going to use are more likely to fail during heavy snow loading. Heres an album showing installation of the best snow guards made . http://share.shutterfly.com/action/welcome?sid=8cbsmrhqzlg | ||

That would mean removing and reinstalling about 70 pieces of slate. I am trying to minimize the impact to the existing roof. Is that my only option? | ||

why not remove the slate as needed,install the guard shank,re-install the slate with a hook? | ||

I am attempting to install retrofit snowguards. They are the long shank type that hook onto an existing nail in the course above. The slates themselves are in excellent condition. The problem I am having is that there is paper laid between the courses which makes it very difficult to slide the guard up to hook the nail. The paper was apparently installed originally to "stretch" the slate. In lieu of face nailing does anyone have any advice or suggestions? |
