I am thinking that Mr. Woodhouse was contemplating random widths and that is why he was confused. If he used random widths with clipped corners, he would be cutting into the headlap. Hey, all is well! thanks Joe. | ||

Yes, you are right Old School. But random width slates are not typically beveled. If they are, the bevel is insignificant for the very reason you mention. Deep bevels such as when slates come to a point require uniform widths. | ||

I read that Joe and something was bothering me about the answer. It came to me today. You MUST be using slates that are all the same size and laying them so that the setback is half of the width of the slate for that to be a true statement. Random widths with a clipped corner may impinge on the headlap, depending on how clipped the corner is. | ||

You are correct. The bevel does not affect the headlap. | ||

I'm pretty sure I've found my answers on this board but to confirm. Does bevelling, fishscaling, etc. slate change the headlap and sidelap? Am I correct in assuming that as long as I don't reduce the length of the slate (16inches), I can make a bevel on each side of a 10X16 inch slate that is four inches up the side and two inches across the face at the bottom and not effect headlap or sidelap? This is being installed vertically for siding on a dormer. I plan to use 3 inch headlap measured from the bottom of the slate. I assume you don't now have to measure headlap from where you make the bevel (i.e. 4 inches higher). |
