Recommendation points
The roof occupies an important place both in the house itself and in its design, and also in the estimate of construction costs. The roof, which will last for tens of years, must be of very high quality, therefore it does not cost two kopecks. Let’s see what makes up the cost of a slate roof for an ordinary one-story house 12×11 m with a warm attic floor.
Correct project
There are general costs for a house project, which can also be attributed to the list of costs for the roof, because the architect creates the roof as an aesthetic element of the appearance of the house, calculates the load that falls on the walls, based on the possible load, offers design solutions and types of suitable materials. The house project costs in the range of 25-150 thousand rubles. depending on the complexity and degree of elaboration, and approximately 20% of this amount can be safely attributed to the cost of designing the roof. The average market price of the project will be: (150,000 – 25,000) / 2 = 62,500 thousand rubles, and 20% of it – 12,500 thousand rubles.
Choose only the best materials for your roof
Quality building materials
It is obvious that it is absolutely impossible to save on the quality of building materials. But this does not mean that any variation within the selected building materials is prohibited. For example, you do not need to spend a lot on the lathing, if you are making a roof from slate, make it from durable wood, but with a smaller step between the bars, since large sheets of slate with a margin will fall on such a lathing without prejudice to further operation. With other materials, such a trick will not work – in order for the residential attic to be comfortable enough, you will have to invest a lot in a solid crate and additional heat and sound insulation.
Often, future homeowners decide to save on fasteners, but such a “benefit” will save a penny, but in the future, low-quality washer-seals can deform and let water pass. The roof will lose its main function – to protect from precipitation.
If you calculate all the costs of materials used to install a slate roof on the online roof calculator, you get the amount of 125 147 rubles. The calculation is carried out on the basis of SP 17.13330.2011 “Roofs”, with a building width of 12 meters, a roof height in the ridge – 5 meters, ridge length – 11 meters, overhang length – 5 meters.
This includes: lathing and counter-lattice, vapor barrier, thermal insulation, moisture and wind protection, gutters, fasteners. Is it expensive?
For comparison, the same roof made of metal tiles will cost 302 856 rubles, and from cheap and popular corrugated board – 265 312 rubles. Flexible tiles are even more expensive – 326 633 rubles. It turns out that slate is beneficial in comparison with any other materials..
But we advise you to spend a little more when purchasing slate for the roof not of the usual gray color, but painted with water-dispersive acrylic paints and varnishes. Such a roof will stand without holes and problems for several years longer than traditional gray, because the application of paint in an industrial environment allows you to obtain coatings with higher performance in terms of weather and light resistance. However, ordinary slate also serves for at least 25 years, but for someone additional 3-5 years are important, because you want to transfer everything valuable to your children and grandchildren.
Skillful hands of installers also contribute to the long service life of the roof
Professional installation
Considering the cost of the roof, you need to consider the cost of the craftsmen. They do everything from the installation of rafters and battens to the installation of additional elements on the finished roof. Their services are not cheap, and each type of work, be it a vapor barrier or installation of slate, is paid separately at a flat rate per square meter. Usually, the pros take in the region of 250-350 rubles. for laying a square meter of the roof. If we imagine that our roof area is about 140 m2, and at least two specialists are needed for installation, then for this expense item it turns out: 300 x 140 x 2 = 84,000 rubles.
The total amount for all cost items: project 12,500 + materials 125,147 + work 84,000 = 221,647 rubles.
