The post will also discuss some changes in the 2021 IRC that affect construction of stick-frame roofs. The 2021 International Residential Code (IRC) had several modifications that clarify construction methods for Steel Deck stick-frame roofs that address some of the issues discussed in this post. Whether it’s because of the growing size of houses, or because roofs are getting more complicated, the code requirements for stick-framing roofs have become more complex over the years. Is allowed by the code to consist of 1x lumber. In August 2021, to complement the existing LSSR model sizes for SCL and solid sawn lumber, we added new sizes to the series to accommodate single 2x lumber. Another product available for supporting 2x miter-cut solid sawn joists is the LSSJ. It can accommodate three typical rafter assembly types: common, miter-cut jack, and plumb-cut jack. A lighter-duty field-adjustable jack hanger, the LSSJ is the ideal hanger for connecting miter-cut jack rafters to hip or valley members. Best of all, it can be installed after the jack rafter is temporarily fastened in place.
One of its key features is that it can be installed after the rafter has been tacked into place. They do not want to leave that place in a ditch-like manner. For example, in Texas, where stick framing is common, there are entire crews specializing only in framing roofs. There are two common ways of framing the roof of a house: with pre-manufactured trusses, or with rafters and ceiling joists, commonly called stick framing. Although truss-designed roofs are predominant throughout most of the residential construction industry, there are regions where building with stick-frame roofs is still common. While truss roofs are the most popular construction style today – by some estimates, truss roofs outnumber stick-frame roofs two to one- there are regions of the country where builders still prefer stick-frame roofing. In this post, Randy Shackelford discusses some design choices available to stick-frame builders, the challenges they pose, and the solutions offered by the Simpson Strong-Tie® connector system for stick-frame roofing. Knowing a significant part of our customer base relies on out-of-the box solutions from Simpson Strong-Tie, we’ve crafted and engineered a system of products that can greatly simplify the construction of stick-framed roofs. Cooling system do you have? Perhaps it wasn’t planned that way, but could this feat have been a premonition of the subsequent popularity of Chevy’s poshest model?
The key to selection is to find plants that don’t have aggressive roots that can damage your rooftop (like bamboo). A leaky roof can damage ceilings, walls and furnishings. Using metal roofs designed to reduce environmental impacts and stand up to climate extremes such as wildfires and damage from hail and high winds, also makes them a better long-term investment. Only the best skylights in the industry can stand up to this type of warranty. Look for good carpentry skills, quality workmanship and moreover the capacity to pass on what they promise by having the best instruments and staff. These factors will determine how to best orient the house. At one time or another, you may think of disposing of your house or use it as a security in the bank. By installing enough PV panels to generate one megawatt of power per day, LACC hopes to lead the way in the use of sustainable energy on college campuses. Section R802.5.2.1 describes the use of ceiling joists to provide the continuous tie. Without the tie at the bottom, the rafters must be supported at their upper end to prevent the rafter thrust at the lower end. The new revision states that the “vertical bearing of the top of the rafter against the ridge board shall satisfy this bearing requirement” when the roof pitch is ≥ 3:12. The ceiling joists or rafter ties provide a continuous tie across the lower ends of the rafters.
Similarly, where ceiling joists are not parallel to rafters or not present, either rafter ties must be installed to provide the tie across the building, or a ridge beam must be installed. Conversely, it implies that when ceiling joists or rafter ties do not provide the tie (and a ridge beam is used), some sort of vertical bearing, such as a joist hanger, needs to be provided at the top ends of the rafters. The wording was revised to change the focus from providing “resistance to rafter thrust” to providing a “continuous tie across the building”, in the hopes of reinforcing the purpose of the requirements. Section R802.5.2 was revised to more clearly cover the three possible cases of ceiling joists and rafters: (1) ceiling joists parallel to rafters and located in the bottom third of the rafter height; (2) ceiling joists parallel to rafters but installed above the bottom third of the rafter height; and (3) ceiling joists not parallel to rafters, or ceiling joists not present. The load-resisting concepts of the vaulted ceiling are completely different. The connectors highlighted below are off-the-shelf, widely available, and economical solutions for the stick-framed roof connection points detailed in the above discussion.
