The device and step of the crate for soft roof

It is essential to comprehend the fundamentals of both the roof deck and underlayment when installing a soft roof. The roof deck provides the structural foundation to which the roof covering is fastened. It is frequently constructed of plywood or oriented strand board (OSB). It gives the roofing system as a whole stability and support. It is crucial to make sure the roof deck is dry, clean, and defect-free before applying any roofing material.

The roofing underlayment is a vital layer that sits atop the roof deck and offers extra defense against water infiltration. The underlayment, which is usually composed of polyester or felt paper, serves as a barrier between the roof deck and the final roofing material. It assists in averting potential water damage that might arise from moisture seeping through the roof covering.

Roof decking is the process of building the structure that holds up the roof covering. In this step, a grid-like structure made of horizontal and vertical beams is laid out on top of the roof deck. These beams—also referred to as rafters or trusses—provide the support structure for the roof covering. To support the weight of the roofing materials and endure weather, it is imperative that these beams are positioned correctly and firmly fastened.

Basic rules for the execution of the crate

The following guidelines are followed when working on the crate beneath the soft roof:

  • If the roof slope angle is in the range from 5 to 10 °, then it is made in the form of a continuous flooring of moisture -resistant plywood or boards;
  • If the angle of the roof is in the range from 10 to 15 °, then it is performed using a beam of 45 × 50 millimeters, moisture -resistant plywood and the direction of parallel cornice with a step of 45 centimeters;
  • With a slope angle of more than 15 °, a beam of 45 × 50 millimeters is used in the design of the crate, but with a step of 600 millimeters;
  • The installation of an additional timber is used in the mounting zone of the yendova and the skate.

Calibrated boards are thought to be the best choice for setting up the soft roof crate. This is because it is challenging to create a smooth surface at the junction when using boards that differ in thickness; as a result, the crate will end up being stepped in this instance. It has been established through many years of use that a soft roof’s service life is significantly shorter in areas where the crate’s surface is uneven.

Stepo-drop variations in the height of the boards are not acceptable; for this reason, high-quality building materials are used and their joints are meticulously adjusted when arranging a roof.

Coniferous trees are a great choice for boards due to their excellent operational characteristics and low cost.

Because of the way roofing materials work, the crate’s step beneath the soft roof can only be 100 millimeters. A solid layer is composed of wood steering plates, moisture-resistant plywood, or calibrated overlaid boards (OSB). The continuous layer needs to be firmly fastened to the boards and have a maximum humidity of 20%.

The following influences should cause the crate’s strength to match the loads it perceives:

  • loads from snow cover;
  • loads from roofing materials.

The best roof design parameters are computed based on these variables. For instance, to build a crate with 500 millimeters of rafters, use a board 20 millimeters thick or ten millimeters thick of moisture-resistant plywood. Boards 30 millimeters thick or moisture-resistant plywood 20 millimeters thick are used with rafters spaced 1200 millimeters apart.

The wood that is used to make the crate is not as resistant to mold and fungus as the soft roof. All wooden structures receive special attention when it comes to the initial antiseptic treatment.

Installation of a dropper

A dropper that shields the cornices from the damaging effects of moisture is one of the key components of the crate for a soft roof. Moisture on the cornices is what causes the rotting and eventual destruction of the wooden structural elements.

Depending on how steeply the roof slopes are inclined, the dropper may bend between 100 and 130 degrees. In order to guarantee that water drains straight into the gutter, the dropper is mounted on the very edge of the roof and given a strict vertical direction downward. Apart from its protective purposes, the dropper enhances the roof’s aesthetic appeal and prolongs its lifespan.

The dropper’s primary characteristics are:

  • The material for its manufacture is galvanized steel with a layer of special coating, increasing the anti -corrosion properties of the dropper;
  • The color of the dropper must correspond to the color of the roof so as not to spoil the aesthetic appearance;
  • The installation of the dropper is carried out along the entire perimeter of the building, which makes it possible to fully protect the roof and facade from the harmful effects of water;
  • In addition to moisture -proof properties, droppers give the roof additional protection against wind.

"The roof deck is the cornerstone that ensures longevity and performance in the construction of soft roofs. Preparing the underlying structure and choosing and securing the right materials are just two of the crucial steps in the roof deck installation process. Comprehending these procedures is imperative in order to attain a robust roof that can endure environmental conditions and offer durable defense. In order to guarantee a strong and dependable roofing system, this article examines the significance of the roof deck in soft roof construction, outlining its parts, installation techniques, and best practices."

The technology of installation of the dropper

Observe the following fundamental guidelines when installing a dropper:

  • Its base is attached to the crate, and the lower edge is directed to the gutter;
  • The mounting of the droppers among themselves is overlapping;
  • To protect the edges of the crate, the front -line planks are additionally installed;
  • After that, the carpet is installed, the edges of which are treated with mastic, which allows you to improve the clutch with the surface of the roof;
  • On top of the dropper, the installation of a soft roof is made.

To guarantee the longevity and efficacy of a soft roof, one must comprehend the composition and procedures involved in building the roof decking, also known as the roof truss or roof crate. The roof crate gives the entire roof system support and structure by acting as the base upon which the roofing material is installed. It is made up of a structure with carefully positioned beams, joists, or rafters to evenly distribute the weight of the roof over the building’s walls and foundation.

The first step in building a roof crate is to measure and mark the layout precisely on the wall’s top plates. In order to ensure that the rafters or trusses are positioned correctly to support the weight of the roof, this layout acts as a guide for their placement. After that, each rafter or truss is fastened to the walls and joined to one another with horizontal beams or purlins, forming a sturdy structure that is weatherproof.

The span of the roof, the weight of the roofing material, and regional building codes are some of the variables that affect the rafters’ or trusses’ size and spacing. Maintaining the proper spacing prevents the roof crate from collapsing or sagging under the weight of the roof. Furthermore, adding ventilation channels between the rafters or trusses aids in controlling the attic space’s temperature and moisture content, avoiding problems like heat accumulation and the growth of mold.

All things considered, building a roof crate for a soft roof requires meticulous planning, exact measurements, and compliance with building codes. Homeowners and contractors can guarantee a solid and long-lasting foundation for their soft roof, extending the lifespan and functionality of the entire roofing system, by being aware of the goal of the roof crate construction process and the procedures that must be followed.
