What Is Standing Seam Roofing?

Sloped roofs are also called inclined roofs, which refer to roofs with drainage slopes generally greater than 3%. Sloped roofs are widely used in buildings, mainly including single-slope, double-slope, four-slope and folded waist types.

The form and slope of a pitched roof depends mainly on the building plan,

The sloped surfaces of a double-slope or multi-slope roof meet each other, and the horizontal intersection at the top is called the positive ridge; the diagonal line where the slopes meet to form a convex angle is called a ridge; A sloping roof without a ridge is called a roll roof. The hard mountain top, the hanging mountain top, and the Xie mountain top can all be made into the form of a roll top.

In addition,

The projected height of the slope on the vertical plane from the slope of the roof (

Common types of support structures for pitched roofs are:

There are many types of roofing materials. When selecting them, comprehensive consideration should be made according to the support structure type, roof slope, building appearance, durability, fire resistance, waterproofness, self-weight, construction requirements, and cost. Commonly used are:

The structure of the roof must be strong and durable, waterproof, fireproof, thermal insulation, heat insulation, corrosion resistance, light weight, simple structure and convenient construction.

Pitched roof insulation

For sloped roofs of heating buildings in cold areas, insulation issues should be considered. There are usually two methods of roof insulation and ceiling insulation. Roof insulation is to place insulation materials below the roof waterproof layer. For example, in traditional construction, wheat straw mud is used to directly tile or light insulation boards are laid under the roof. There are two methods for ceiling insulation: one is to lay lightweight thermal insulation materials on the suspended ceiling; the other is to use the thermal insulation performance of the suspended ceiling material itself. In the design of these two methods, attention should be paid to the ventilation, moisture-proof, anti-corrosion, and fire prevention of the insulation structure.

Slope roof insulation and ventilation

The purpose is to reduce the indoor influence of radiant heat and protect roofing materials. In a covered sloping roof, ventilation in the mezzanine space between the roof and the ceiling can be provided at the cornice, ridge or gable, or ventilated tiger windows can be opened on the roof.

Canopy

The cornice is the interface between the roof and the wall to protect the wall, and it is also a decorative part of the building facade.

Pitched roof

According to the length of the cantilever, there are many ways to do it: you can use the brick to eave the less; you can use the rafter to eave the eaves, the eaves or exposed, or nail the eaves; The eaves wood pressed into the wall is taken out, and eaves are set to increase the depth of the eaves.

Sloping roof drainage

The rainwater on the sloping roof can be drained freely along the roof through the eaves; horizontal eaves with a slight longitudinal slope can also be set at the eaves, so that the rainwater is collected under a certain distance of vertical rainwater pipes and discharged.
