Of course, the construction of the roof is the completion of the entire building. Therefore, the quality of living in the house, its durability and reliability depend on this element. It is for this reason that roof drawings, which we will discuss in our article, are of great importance in the construction of a house.
Roof design
If we consider the importance of each structural system of the house, we can determine that the roof is superior in general value to other elements. In this regard, when constructing a roof, considerable attention is required.
Before starting roofing work on construction sites, it is necessary to draw up drawings of the roofs of houses, that is, to design the roof, taking into account the main functions that it must perform at a qualitative level.
Roof options
Before starting the design, it is worth deciding on the most suitable design option.
Advice. To do this, explore the many options and stop at the one that will fit the house in all respects.
When choosing a roof structure, you should consider whether it is suitable for the climatic conditions of the area where the house is being built. This is determined in order to choose the right roof material and roofing.
Advice! If your house is being built in an area where gusty winds prevail, then you should not choose a structure with a high roof. Since it is less resistant to natural loads. On the contrary, if the area under the construction site is characterized by heavy snowfalls, then the roof structure should be chosen higher and steeper so that the snow does not linger on the roof, in order to prevent moisture from entering under the roof.
Flat roofs definitely do not perform their functions. Therefore, it will be correct to build pitched structures on residential buildings. The pitched roof is able to resist such atmospheric phenomena as snow, rain, fallen leaves.
The design of the roof with a slope prevents debris and precipitation from being retained on the roof, which contributes to the reliable protection of the roof from the damaging effects of moisture and untimely damage to the roof structure.
Drawing up the drawings of a pitched roof, you can make additional ideas or major changes in engineering.
Of course, everything should happen within reason, since the ability of the roof to perform its functions depends on the features of the roof structure:
- reliability of the roof structure;
- home safety.
Drawing Executors
A document such as a roof drawing is made individually for each project. Self-compilation can lead to negative consequences.
Many developers, when performing drawing work, are guided by SNIP standards, use auxiliary literature, but at the same time make many inaccuracies. Subsequently, the drawing is not approved by the architect.
Advice. Therefore, in order not to do the same work twice or spend time and money on correcting errors in the drawing, it is better to immediately entrust its compilation to specialists of architectural institutions.
Therefore, trusting professionals, you will be sure of the correct drawing up of the drawing and the reliability of the roof structure.
The process of creating a drawing requires a thorough understanding of the complexity of the process, which directly affects the construction and operation of the roof. .
Stages of drawing up a drawing
The start in drawing up a drawing begins with determining the pitch and shape of the rafter legs.
In order to correctly determine the thickness of the material for the rafters, it is necessary to consider:
- roof slope;
- type of roofing;
- climatic features of the region.
The next stage after the start is to determine the number of truss structures. The person who draws up the drawing of the roof of the house must determine the best option for the truss structure.
She may be:
- oblique;
- hanging.
Hanging roof truss system is installed on two load-bearing walls. Sloped rafters are reinforced with load-bearing columns or a middle wall.
Planning also includes the calculation roof battens (basics).
Roofing lathing is divided into the following types:
- for rolled and soft roofing - solid;
- for a wavy sheet roof - ordinary (intermediate).
When calculating the crate should take into account roof pitch and type of roofing material. In addition to the above points, when drawing up the drawing, the presence of fasteners, auxiliary stops, which will be located on the roof structure, is taken into account.
Drawing composition
Be sure to design the roof + drawings contains a clear idea of the truss system and calculations for it.
In addition, the drawing, depending on the design, contains the following information:
- a plan for joining the roof with a clamping profile to the parapet;
- adjoining without clamping profile;
- plan of the operated roof with a doorway;
- junction of several slopes;
- installation of drain funnels;
- roofing tray scheme and so on.
It is not enough that the drawing contains only a schematic representation of the type of roof proposed for arrangement.
Of course, according to the scheme, you can determine the type of roof:
- lean-to;
- tent;
- hip;
- flat.
But this is not enough in construction.
Attention. The drawing must be drawn up taking into account all the nuances and calculating the size of the forms and the amount of material.
Where can I get a drawing?
Surely, many are faced with such a situation that they like the drawing, but it does not suit you from the point of view of financial considerations.
So we begin to act on the principle of economy, just like the Matroskin cat from the cartoon. Only he has a cow - milk, and here the roof and the reliability of the house are at stake.
So think about it, is it worth it to draw up a drawing yourself, if there is no necessary knowledge base for this? Will such savings turn into big waste?
In our opinion, it is better to entrust this serious matter to professionals - architects, designers. Only then will you be 100% sure that your actions are performed correctly.
What kind of roof you have over your head depends entirely on your choice. Remember that when arranging it, special attention should be paid to all stages, from the moment the drawing is drawn up, until the installation of roofing materials and the gutter system on the roof.
