Roof drop is a whim or need

The independent construction of any building, which implies the presence of a roof, requires experience in its implementation or competent guidance. For example, is it necessary to mount a drip for the roof or will it be good without it? As the experience of other builders and residents of the constructed houses has shown, its presence is still welcomed. Why?

The main task, which is assisted by the installation of a drop cap on the roof, is to protect it from moisture, from the accumulation of liquid and from the destruction of the roof rafters (their decay). But also a drip cap is installed on window or doorways, it is also a protection against moisture, which appears during different kinds of precipitation. It is not worth saving on this, although many workers offer this option to their customers, arguing that the hydro-tar is enough. This very hydrobarrier, on which condensate is collected under the main coating, simply must (!) Have its logical completion, and this is nothing more than a drip for the roof.

The economical option - to remove the film from under the roof, which inexperience can do both by self-workers and construction workers - shows its failure on many examples: the action of the sun and the wind quickly turns this film into nothing. In addition to losing its functional properties, it also significantly disfigures the appearance of the building.

Roof, which requires a drip

Any type of roof implies the presence of a protective layer (hydro-barrier), and it is not superfluous in any case, whether it is soft bituminous coating, ceramic tile, slate or seam roof. So, any type of such a roof should have a drip. If you are 100% sure of the protective properties of the coating and you will not spend extra money on the hydrobaryar, then the expense item for droppers also falls. But he pays a miser twice, right?

If you do not know how to proceed, if you need a chapel for the roof, try at least to calculate your approximate costs for additional protection.

Ten minutes of calculations - and see the benefits

Suppose that the attic will not be residential. In this case, you only need one layer of film. If you intend to use the attic as a living space in the future, then you need to protect against moisture of two types: steam protection (inside the attic, over the heater) and moisture protection (between the heater and the roof), that is, two layers. Why do I need a layer of protection from the inside? It protects against moisture, which accumulates indoors. In the case of a non-residential attic, we sorted it out.

The next step is to take the roof plans that you have selected for your house, and calculate their size. Suppose that the quadrature of the chosen roof - 150 square meters. The area of the standard roll of waterproofing is 75 square meters. Meters, and it costs about two thousand rubles. Total - four thousand for waterproofing.

And how much do you have to pay for the drip?

We calculate the length of those sides where the chapel for the roof will be installed. Let's say 30 meters for a given quadrature. Kapelnik, whose price from 85 rubles and above, you need to choose based on its properties specified by the manufacturer, and recommendations for a specific type of roof. Suppose that you are an option for 140 rubles / pog. Meter - drip for metal from the domestic manufacturer. Total another 4,200 rubles.

In the amount of slightly more than eight thousand rubles for waterproofing. It would seem expensive, but if you found money for 150 square meters of metal (and this is at least 45 thousand rubles), is it not wise to find a little more to buy a hydraulic barrier and a drip - for the roof and for your own peace of mind?

Simple conclusions from the above material

Roof projects that you can offer from existing ones or develop for you construction companies will contain more correct calculations, since the installation of insulation will require appropriate hardware and adhesives. A solid, impenetrable roof is a reliable protection for your furniture, electrical appliances, decoration materials, which cover the walls, the ceiling - for everything that is inside the house. And life in a rainy region requires additional protection. It would be much cheaper to lay a film under the roof, than to do anew repairs.
