Apply Roofing Underlayment and Shingles

don't screw myself over all right I got one and one only package of shingles did not measure how much I need but I kind of did the old one box should be fine probably going to be right but we're going to find out if you don't remember on the sauna build the way to install them is you kind of have a three- tier pattern I think they call a three tab pattern uh cut the first one in third keep the two piece or the the the 2/3 and then take a full sheet so there's your pattern start with the first one give yourself a nice uh I don't know/ inch overhang on both sides it'll only make it better just because the water will drip off and half the time it probably won't even hit your drip edge and hit your four roofing nails evenly spaced throughout the thing don't go too high don't go too low and don't go too much on the edge and most importantly make sure it's sunken flat so water doesn't get seeped into it if it's one of those weird nails that go sideways might be an opportunity for a leak
