Tree house roofs1/20/2024 Pre-drill the decking screws and put them about halfway in so when you put up the trim, all you have to do is fasten the screws all the way. A couple of coats is recommended.įor trim, we used 1×4 cut to size, with 45 degree miters on each end. You can use a paint sprayer or roll it on, whichever you prefer. Once the roof was up and the siding was finished, it was time to paint. Grab the ridge cap, put it in place, and fasten it with screws every 9 inches on the ridges. Start by placing some adhesive seals, working your way down the ridge. □ Without a lot of support up there, just go slow and be careful. The toughest part of doing the ridge cap was just getting up there and working on the roof. Use the same cutoff wheel to cut off any excess flashing. Use a Sharpie to mark you line, and a cheap cut off wheel from Harbor Freight to cut it to length. When you get to the end piece, you’ll most likely need to cut it to fit. Make sure your panels are overlapping as you go from one piece to the next. Attach the roof panel to the flashing and framing. These are available at the metal supply store as well. Almost forgot about that! You need to use a foam seal in between the flashing and the roof to keep water and wind out. Drive two screws on each valley on the roofing, securing it to each of the 2×4 runners you put into place earlier.ĭon’t forget your metal flashing, which goes underneath the roofing panels. They have rubber seals/washers that help keep water out. The screws that you’ll use for the metal are a special type for this exact application. They can cut these to length, but we lucked out and found some that were the right length already. ![]() These are 3 ft wide and availabe at most metal supply stores. Fasten each board with outdoor rated screws to every rafter to make sure there is good connection.įor the roofing itself, we used a ribbed 29 gauge steel roofing panel. Put one on the top, in the middle, and on the bottom on either side of the roof. Next up we put some 2×4’s running the length of the roof, which is what we attached the metal roofing to. These usually go on the outside, but we put them on the inside in this case. ![]() Use hurricane ties/straps to strap everything down. With your 4 end rafters in place, use a measuring tape to mark where your other rafters will be (every 2 feet on center in our case), which will make it quick to attach the rest of them. To make it easier to mount, pre-drill the screws, and then attach them by driving some screws on the underside of the walls, and then driving through the tops, near the ridge.ĭoing the rafters on each end gives you the ability to make sure the ridge post is nice and plumb. The rest of the rafters will be full length. This is the case for both ends of the roof (front and back) so 4 boards in total will be a little shorter. When putting your rafters up, keep in mind that the first one on the edge is going to be a little shorter in length due to the ridge post you’ve put in place, so take about 1 1/2″ off of that one, and the one on the opposite side. Some people choose a circular saw for both. Use a circular saw to cut out the angles, and a jigsaw to cut out the birdsmouth for a nice straight cut without cutting more than you need to. ![]() It may be easiest to create one single tempate out of your first board that you can then transfer to the other 2×4’s to make multiple, consistent rafters without having to make multiple measurements for every single board. (The birdsmouth is where your common rafters connect with the framing around the walls.) It will even give you a PDF to scale to use on the board and use it as a template for cutting out the birdsmouth. It’s completely customizable on the website, and will provide and exact cutout of what the birdsmouth will be. They have a great truss calculator that helps you figure out what your rafter length needs to be, what the angles will be this depends on the pitch, the overhang, and the rest of the dimensions that you put in. Our clubhouse is 10 ft x 10ft, but yours may be different.
