Few private home builders admit that built a house for sale. This is one of the rare occasions that buyers will be suspicious of a home, which is not surprising. Homes built for sale suffer from many disadvantages. It's like a houseplant from a supermarket. It looks good only for the first week, and then it begins to wither and die, because it is not adapted to real life. The same is true for most houses built for sale: a beautiful picture, which then turns into a harsh reality. And you can list the problems from foundation To roof and vice versa - as you like best. Well, for example, let's start with the roof.

Drains that don't work
A beautiful roof is part of the picture for sale. A chic color that matches the facade and the elements of the fence - and you are ready to open your wallet.
The further the rainwater is diverted from the walls, the more durable the entire building. But in order to properly drain the water, it is necessary that the gutters be up to 12 m long, no more. If more, then the water will overflow and flow along the wall and on blind area. If the length of the gutters is more than 12 m, additional elements must be installed to prevent overflow.
The presence of a monolithic belt
Basic knowledge of roof design is important here. If the roof is spacer, then the force vector in it is directed from the axis of the house along the horizon, and in this case the monolithic belt is necessarily closed along the entire perimeter.
If this is a non-expansion system, then the load falls on the ridge beam, and the roof rests on the walls only vertically. In this situation, a monolithic belt is unnecessary.
Why is it important to look at the crate
Roof decking is an important choice, but it is equally important to choose the right sheathing and rough decking for it. If you chose metal roofing - then you need a lathing and counter-lathing, and for soft tiles - lathing and flooring made of OSB. But in any case, it is important that the counter lattice is made of a bar with an edge of at least 40 mm and a good clearance for ventilation.
Rafter step
Why is it important to design all the elements of the house first, taking into account all the properties of materials and permissible loads? Many neglect this rule for the sake of economy, relying on experience or available information. And this is wrong.
You should not take an average step of 60-100 cm as a basis. There are a lot of nuances that need to be taken into account: the attic floor or not, what is the length of the rafter leg, the type of coverage and much more. As a result of accurate calculations, we will get values from 0.6 to 1.5 m, and this is a large spread and a significant difference in the price of the structure.
Not all wood is rafters
Not only that the rafters must be at the right distance and made of the material of the required dimensions - you need make sure that they are free of bark residues, wane and must be treated with an antiseptic and fire retardant.
How is the vapor barrier installed
There are a large number of vapor barrier films on sale from different manufacturers, but even professionals can confuse the front and the wrong side of the material, and the efficiency of work directly depends on this roofs. You can find out if the film is correctly placed using the manufacturer's website.
Why is it important to drive a nail correctly?
And this is also important, because incorrectly installed fasteners negate all the efforts described above.
You see how many nuances there are in the roof alone. And if only these were all possible mistakes! Watch this helpful video:
