![]() ![]() ![]() Hip Roof - has slopes at the end of the building as well as at the two sides. Mary and I know that our roof pitch table and rafter information below will make it easier for your calculations. The gable roof is the most common type of roof. Gable Roof - has two sloping sides that meet at the top to form a gable at each end. Sometimes used for an addition to an existing structure (being attached to the side of the structure or to the roof) Shed Roof - or a lean-to roof, have slopes in one direction only. Rise and Run means that a 6/12 pitch roof has 6' of rise (vertical) for each foot of run (horizontal). Roofing Calculator is mobile and accurate, fast and offers an abundance of features, makes life easier for everyone involved in a project for building a roof. Our roof rafter calculator tools are handy for calculating the number of rafters needed, rafter length calculator, lineal feet of rafter, board feed in ridge and sub-facia,and the total board feet in the roof. House Roofing Calculator is designed to help architects, engineers, construction professionals, field technicians, builders, framers, carpenters, handymen and contractors, designers, drafts persons. Fast calculations and design, ideal for roof builders.Īfter calculation, you can see the graphical roof, rafter, hip from side to top in 2D drawing exactly how you like it. You’ll need to speak with an actual representative and likely schedule a roof inspection to determine specific quotes.House roofing calculator is a powerful and user-friendly roof calculator used for designing and calculating shed roof, gable roof, common rafter and much more. Of course, our roof truss design calculator doesn’t provide a guaranteed calculation or price. This will be done with steel joints and a bridge, added to support the weight of the entire truss. Our truss calculator computes the best dimensional method to connect the pieces of the truss. This allows you to better estimate purchasing costs, as well as labor costs from a reliable roof truss designer and installer. Roof rise This should be calculated from the base of the roof to the highest point of the roof gable (the peak). Once you have the roof overhang, pitch, span, and rake length calculations, you can better understand just how much material you’ll need. Rafter run outer wall This should be measured starting from the center of the roof span, and then extending to the very edge of the exterior wall. A “gable end” refers to the entire wall, including the gable (triangle portion of the wall) and the wall below it. Your roof “rake” is essentially the measurement of the sloped sides of a gable end. Unless you’re a builder or roofer, you likely haven’t heard terminology like “rake length” used much - and that’s okay. What can you do with this information provided by our roof calculator? Well, knowing the roof rake length helps you understand how much the truss project will cost and what materials you will need. ![]() Common industry spacing for rafters is 12, 16, 19.2, and 24 on-center with other spacing used where design, climate conditions, and Engineers identify them. Simply enter the measurements and our handy tool will calculate your “ rake length” instantly. Roof joists should be nominally 2 wide and 4 to 12 deep, although larger dimensions can be used.
