One hundred and troubles with the roof due to incorrect arrangement of screws

I think it will be about banal things. However, a couple of times I've seen this mistake even the "roofers," therefore I shall tell more. Information, no doubt, will be useful for those who want their own hands cut off the roof with metal and makes it the first time.

Mounted crate with a standard pitch - 350 mm. It's time to install and fasten the sheets. If someone put in front of this fence of metal sheets, the technology is familiar: the first screw tightened, pulled the cord along the boards lathing, leveled at him the rest of the holes and twist. It is with this approach, there is a lot of problems.

We have a lot of time to spend on the manipulation of the cord. Constantly flip it and try to get to the board. If you put off the distance on the roulette wheel, there is always a risk to get off and get into the "milk". Manufacturers of metal they think of us, and all provided.

Step crates duplicates each wave. Screws securing the right place - just under the "stepping stone." Then I do not have anything vymeryat. Risk fluff past the crates also reduced to zero. But it's not the only problem.

The farther from the "step" you thread the screw, the greater grows the gap between the board and the sheet metal. It comes to the fact that the screws are held in the timber only by their tips. If clamping them against the stop, the metal sheets are deformed.

With proper installation of the cap screws fall into the shadow of the "steps". When viewed from the ground, they are almost not visible. The roof looks nice and tidy. Observance of technology avoids many problems. Do not neglect materiel! And, of course, thanks for reading! If the article was helpful, subscribe to the channel.
