Roofing industry experts agree that in order to properly frame a roof, the proper tools and measurements must be used. Accuracy is key, and in order to make sure your roof frame is accurate you’ll need to start with accurate information. This article will help the lay person understand the fundamental concepts dealing with how to frame a roof.
Before making the first cut a plan must be designed. The roofing plan is the blueprint that will help you create a well built roof frame. After the plan is created the pattern can be cut out using power tools. The ridge board’s height is indicated by the rise and slope of the roof rafters.
Most of the time a professional carpenter with years of experience with the construction of frames will build the roof frames. These carpenters have a skill that takes years of training to perfect and can create beautiful works of art. However, recently, the craft of how to frame a roof is dying out because of the modern pre-fabricated roofs that are becoming popular. When detailed customization is required, traditional conventional framing still wins the day.
There are several common types of roof framing rafters. Tail cut, plumb cut, ridge board, are just a few of the parts of roof framing rafters. Roof rafters need to be measured precisely and cut cleanly. This process starts by calculating the pitch, length of the rafter, and lumber size. Spacing between rafters is also taken into consideration when cutting. In modern buildings, the width is determined measuring the distance between framing rafters.
The next step in the process of how to frame a roof is determining the proper lumber length. These should be chosen with the horizontal run of the rafter kept in mind not the span of the rafter. In order to make sure your measurements are accurate, a roofing calculator can be used. Some websites even have calculators available for you to use for free to make your life easier.
Next you will need to find lumber that is straight and lightweight. This lumber is used to create a pattern for your frame. Many rafters will be used in this process, so the lighter lumber you select the easier it will be for you to create the design.
When cutting the lumber, make sure you mark carefully and always cut at the appropriate angle. It would also be wise to mark the outside edge of your building on the rafter.
The overall size of the building is what will dictate how big your roof frame will be. If you are framing a small shed, 2×6 or 2×8 rafters will due just fine, but for houses, 2×10 or 2×12 rafters will need to be used. Just remember, the shallower the slope of the roof the larger pieces you will need for the roof frame.
Framing a roof can be a rewarding experience as a home owner. Just remember that accurate cuts are key to a successful frame.
