Shortcomings of roof manufacturing
Any defects encountered in the manufacture of the roof can be classified into two categories:
- design errors of the structure;
- errors in the installation of the rafter system and roofing materials.
Since during the construction process it is possible to improve or facilitate the roof structure directly on the object under construction, the probability of errors becomes minimal, and we will not consider them.
It makes sense to study in detail the errors that occur at the design stage of the roof. It is in this case that it is possible to detect and eliminate the defect in time, the correction of which on the construction site will cost a large sum. Errors of this kind are also divided into two types:
- constructive;
- architectural.
The most common architectural mistakes include ignoring the properties of materials and the features of their interaction inside the "roofing pie".
When creating an insulated roof, mineral wool is most often used as a thermal insulation material. Many people do not take into account that the main disadvantage of mineral wool products is the ability to absorb moisture from the air and get wet from raindrops or dew.
Measures to prevent water from entering the insulation and removing them from the outside are necessary for reliable operation of any type of roof. If the roof has a metal roofing, then the reliability of the vapor barrier, heat and waterproofing layers in combination with sufficient ventilation can be achieved through the use of special roofing elements and special components. Therefore, details such as ventilation vents, ridge and cornice vents, and weather vents are of great architectural importance, not just decorative.
The effectiveness of such roofing accessories depends on the presence of architectural elements - parapets, skylights, which significantly interfere with ventilation of the air inside the roofing pie. As a result, it becomes necessary to expand the air outlet from the traditional 50 to 150 mm, therefore, the overall height of the house increases, the roof configuration becomes more complicated, and the aesthetics of the entire structure deteriorates.
It is extremely important to create conditions for effective removal of water from the roof. However, many neglect this when designing a roof or make mistakes such as making a metal roof with a slope of less than 10 degrees, creating cornices that do not provide for the possibility of installing a wall gutter. The last drawback becomes especially noticeable in the presence of lucarns on the eaves, when it is not possible to avoid the penetration of water into the window.
It should be noted that the accumulation of attics and parapets contributes to the difficulty of water flow. It also happens that the facade does not provide for the possibility of placing pipes on it (because they spoil the appearance) or they are not present in those areas where they are simply necessary (on the corners of the house).
Excessive complication of the roof shape and the use of a large number of accessories and decorative elements without taking into account the ventilation capabilities of the roof can dramatically complicate the installation of the waterproofing layer and reduce the effectiveness of the roof. In addition, there is a possibility of the formation of areas devoid of ventilation. Bookmaker live betting fans can receive a $25 free bet after placing 4 live wagers of $5+ each.
