minimum roof slope calculation : useful tips

Definition roof slope.Determination of the minimum slope

Construction concept of "bias" due to the slope of the roof.This accommodation slope angle to the horizontal surface.Smaller degree angle makes the roof slope is steeper.Angle calculation is based on the principle: the height of the ridge board divided by 0.5 times the width of the room in percentages - multiplied by 100. Visually: width 20 m and height 5 m and get a share of 0.5, multiplied by 100 and receive 50%.

At the minimum angle of impact climatic conditions of the terrain.The slope of 30 degrees is used in regions with abundant precipitation.In arid areas of the roof are constructed with a slope of 10-25 degrees.

Building material - metal - used in the structure of buildings of different complexities.Exception - the minimum angle of inclination for the metal is from 14 degrees, no less.This inclination is able to withstand strong gusts of wind, unlike the snow, not having the ability to roll with such a small slope.

minimum slope allows you to save on building materials.Reliable and solid foundation of the roof creates a wooden crate, a little distance between its mounting boards makes a solid metal.

few tips on installation and coordination of the minimum angle of inclination of the roof

Important recommendations:

1. Layers of metal should be put on a perfectly flat surface, the height of a number can not be more than one meter
2. Take layersshould be in the building gloves to protect the hands from damage
3. Keep reservoir needed for
4. edges securely fastened metal roofing to the crate construction screws
5. walking on the roof of metal tile in a special soft shoes without damaging the surface of the roof, do not step on the waves tiles
6. cutting of metal should be carried out by prior scheme, measured off the right size sheets

preliminary processes:

1. Rafter system must be fully prepared.Measure rays
2. Existing error triangular shape eliminate dobornye details
3. Get rid of moisture between the metal tile and insulation layer is recommended because of the crate (height 0.4 cm)
4. leave a gap of 0.5 cm in the casing of the eaves truss
5. On board Stela waterproofing.From the edge of the eaves board waterproofing must have sagged 0.2 centimeters.Joints waterproofing stele with an overlap of 15 cm.
6. special insulated roof slabs.We put them between the rafter boards
7. Apply the next layer - a vapor barrier

Mounting batten

Crate - an important element of the roof.It is installed on the truss system.It consists of the same boards.They pre-treated with an antiseptic solution.The distance between the boards, lying on the edge of the eaves - 30-35 centimeters, the next - 35-40 centimeters.Metal is attached to the crate on the wave troughs.

By eaves board screwed downspout, which provides a uniform flow of rainwater.Cornice is set on the edge of metallocherepichnoy roofing screws with a flat head.Coincidence is constructed by overlapping an average of 7 centimeters.Solid sheathing is used near the chimney.Endova installed in the interior of the roof joints (overlap - 10-15 cm).

Additions installation of the roof and the regeneration of its minimal slope

Mounting roof provides a comprehensive process and avoid important nuances impossible:

1. not install metal roofing in the upper bending wave
2. Screws screwed nottight
3. Do not use a hammer
4. Screws screwed in with a special lining
5. When cutting of metal is necessary to use electric clippers or other special tools (do not use grinders)
6. Do not use construction foam

slope of the roof is formedthanks to the rafters structure, they create an angle.Details of the roof assembly and installation of its minimum angle look at the video in the next tab.
