There are also travel expenses and consumables (fasteners, tools, etc.) that have a weak but noticeable effect on prices. Take the roof in the projection of the square of 10h10m. If this is a ramp then we should not skate, drain system is only on one side – 10m. In the case of a gable roof ridge length will be 10m, and the spillway chute 20m – on both sides. In hipped roof ridge is going to need about 25m, and spillway system will go around the perimeter – 40m. From these simple calculations, it is clear that the overall price per square meter of roofing material in each case will be different. Even without waterproofing and ventilation output price set the roof in half – two times the price of one only roofing material. And we took a very simple roof.

At a more complex roofs difference in the price of the kit and roofing material increases. Noise roofing material. First of all, this characterization applies to the noise produced by raindrops. Noise, of course, makes any roof, but there is a widespread view that the metal is particularly noisy. Hard to say, where it went, maybe it's one of the producers of competitive advertising moves a roofing material.

In any case, from personal experience and the experience of many friends can say that this is an exaggeration. The biggest noise effect, probably have a flat metal roof. This is due to the fact that raindrops tapping on the plane as the drum, and if the roof is still poorly secured, it creates a vibration that amplifies the noise. On the other hand, the metal profile has no planes, unless somewhere in the design of the roof did not use a smooth sheet. Consequently, the noise and produces very little metal. Take the roof of the projection represents the 10h10m square. If this is a ramp, then we should not skate, drain system is only on one side – 10m. In the case of a gable roof ridge length will be 10m, and the spillway chute 20m – on both sides. In hipped roof ridge already need about 25m, and spillway system will go around the perimeter – 40m. From these simple calculations, it is clear that the overall price per square meter of roofing material in each case will be different.
