Cost of turnkey roof construction per 1 м2

You make the decision yourself — to do everything in stages or turnkey. In any case, it is important to follow a clear sequence of work, technology, and material selection. The cost of the work performed by our company is very low. Don’t forget about that.

How the quality and price of building materials affect the roof
 

The choice of building material is a very important moment. The price in this case plays a secondary role. The main thing is high quality work and time-tested material. Here is an example: Hydro-wind protection is provided by many manufacturers on the market. The cost is practically the same for everyone. But for some, the service life is a couple of years, while for others, it is more than 50 years. It is important to select the right grade of wood, as the third grade of wood can withstand a load that is twice as low as the first grade. There are many nuances. We recommend that you familiarize yourself with the information in the section — quality of building materials.

As for roofing, we have professional roofing contractors JRD 200 and new roof installation LTKV 400 available for you to choose from.

Types of roofs and their impact on installation
 

There are many types of roofs, differing in their working time, complexity, and more.

1. Single-pitch roof

   They are very simple in installation and design. The material cost is small.

2. Gabled roof

   In terms of design and installation, it is the second easiest. Everything will depend on the size of the box.

3. Hip roof

   More materials are required for this type of roof.

4. Hipped and valley roof

   Pure hipped and valley roofs are quite rare because they require additional structures. Nowadays, this roof is one of the most popular, as it is beautiful and diverse in options, installation, and design. The work complexity is above average.

5. Half-hipped roof

   Not the most common option, as it is not suitable for every home.

6. Arched roof

   One of the most complex in design and installation. It is built from wood, not metal, and can withstand heavy loads. Many non-standard solutions must be made during construction.

7. Shed roof

   Quite simple in design and construction, but not encountered often.

Find more detailed information in the sections on our website. The more options, the more difficult the roof is to construct.

Video instructions for installing a roof yourself
 

In addition to construction and design, our company also provides free education. We have made a video tutorial for you on building houses, foundations, roofs, etc. Before you start working, you should calculate all the loads. This is a very important point. For more information, see the video instructions section.
 

Do you need a roof project?
 

Every competent project consists of such sections as calculation of project documentation, details, video instructions, etc. It is almost impossible to do everything correctly without a project. It is not worth relying only on the experience of builders when calculating loads.

Common mistakes when installing roofs
 

Many make mistakes during construction. The most common ones are:

1. Using non-kiln-dried wood. For example, pine with a moisture content of 12% has a strength limit of 86, and at 30%, it is already 49. As you can see, the difference is almost 2 times.
2. Purchasing 3rd grade wood. 1st grade can withstand loads almost twice as much as 3rd grade. If you make a mistake, you can confidently say that the roof is unlikely to last the first winter.
3. When installing the rafter system, it is often necessary to extend the rafters. Many do not put a support at an angle, which leads to sagging and damage to this node.
4. Not calculating the eaves. This is the most heavily loaded element of the roof, it must be calculated separately, and the material for its construction must be selected correctly.

These are some of the most common mistakes. You can see the extended list in the section on roof installation errors.

Frequently Asked Questions about Installation

 
Question: What is the ridge made of?

Answer: The ridge experiences minimal loads and there is no need to calculate stress there. The most important thing is stiffness, i.e., thickness. It is important for it to be as even as possible.

Question: I have a truss on my roof, do I need to attach it to the floor in any way?

Answer: Yes, it needs to be secured to the base with reinforcing bar soles, bolts, etc.

Question: How do I attach the overlap joint itself?

Answer: The joint itself is calculated based on such indicators as the slope angle and the type of wood used. The most popular methods are 12-diameter bolts and nails.
