VALLEY RAFTER Meaning and
Definition
-
A valley rafter is a critical structural member that plays a fundamental role in the construction of a roof in residential or commercial buildings. It is a diagonal beam that runs from the ridge board, or the highest point of the roof, to the wall plate, which is situated at the top of the wall.
The primary function of a valley rafter is to provide support and stability to the roof structure, particularly in areas where two parts of the roof intersect, creating a valley. In this context, a valley refers to the internal angle formed by the intersection of two roof slopes. The valley rafter essentially carries the load of the roofing materials such as shingles, tiles, or metal sheets, as well as any weight applied on the roof, such as snow or rain.
Valley rafters are typically made of wood or engineered lumber, chosen for their strength and durability. They are carefully designed to withstand the pressure and stress exerted on the roof, ensuring the integrity of the structure. Additionally, valley rafters also help to direct rainwater and melting snow away from the roof, preventing water accumulation and potential damage.
In summary, a valley rafter is a inclined beam that offers structural support and stability to a roof, particularly at the intersection of two slopes, forming a valley. It carries the weight of the roof materials and external elements, playing a vital role in maintaining the overall integrity of the roof structure.
Common Misspellings for VALLEY RAFTER
Etymology of VALLEY RAFTER
The etymology of the term "valley rafter" comes from the combination of two different words.
1. Valley: The word "valley" traces its origins back to Old English "wælġ" or "wealġ", which referred to a low-lying land between hills or mountains. This word has Germanic roots, and it eventually evolved into the modern English term "valley".
2. Rafter: The term "rafter" originated from Old English "raefter", which denoted the beams used to support a roof. This word shares its origins with Old Norse "raptr", both of which can be traced back to the Proto-Germanic root "*raftrijaną", meaning "to furnish with beams".
When combined, "valley rafter" refers to the structural beam used to support the junction where two roof sections meet in a valley.
