The verandas attached to the house are a familiar structure, and there is nothing surprising here. But an unusual approach to organizing a place for recreation can be called the arrangement of a terrace on the roof of a building. Previously, such projects were developed for government agencies. Now the roof terrace of a residential building is present in many private courtyards.
Planning is an important step in setting up a terrace
The terrace itself is a simple structure, but its location on the roof complicates the design significantly. A serious approach to the preparation of the project is required. You need to take into account everything: a solid and waterproof roof under the terrace, arrangement of fences, design, and many other important issues.
Before you start drawing up the project, you need to assess the building on which the terrace is planned to be erected. Most often, such places for recreation are equipped on the roof, an extension adjacent to the house, for example, a veranda or a garage. The terrace can also be located on the roof of a residential building, but such projects are usually developed before the construction of the entire building.
When evaluating a building, it is important to pay attention to the walls and foundations. The second floor will put a lot of stress on these building elements. Suppose a light veranda assembled using frame technology will not withstand if such a resting place is piled on top. Indeed, in addition to the mass of the terrace itself, you need to take into account the weight of people, furniture, etc. But on the roof of an extension made of brick walls and a concrete foundation, you can safely build such a resting place. However, here, too, it is necessary to calculate the maximum permissible load on the building.
Features of the arrangement of the floor
The biggest problem in the arrangement of the terrace is the floor, as it also serves as the roof of the subordinate building. If done incorrectly, there is a risk of flooding during rain or melting snow.
The base of the roof terrace of the building is floor slabs or wooden flooring. A pie made of vapor-waterproofing, insulation and reinforced screed is laid on top. Moreover, this entire layer is made at a slope of 2about towards the drain funnels so that water does not accumulate on the terrace floor. For such flat roofs, an internal drainage system is usually equipped. Its peculiarity is that the gutters are embedded inside the walls and under the concrete screed, which serves as a roof. Drainage funnels remain on the surface, covered with a protective mesh.
To arrange a roof terrace, perform the following steps:
- First, waterproofing is laid on top of the floor slab. Roll materials or bituminous mastic are suitable. The next layer is vapor barrier, and on top - thermal insulation. Insulation is used only solid. No kind of mineral wool will work. From above, the thermal insulation is protected by at least 5 layers of roll-up waterproofing. The entire cake is covered by the leveling concrete screed.
- The final layer is waterproofing again. A carpet is arranged on the roof, consisting of a mixture of bitumen mastic with gravel.Reinforced concrete slabs with a size of 40x44 cm, lined with ceramic tiles with a corrugated surface, serve as a clean floor. Instead of slabs, the floor can be covered with decking.
Together with the arrangement of the floor, you need to worry about the parapet, because the safety of rest depends on this. You can install the structure as a stair railing. Forged elements and handrails made of natural wood look beautiful. The continuation of the house wall, protruding above the terrace floor, can serve as a parapet.
Outdoor recreation areas are susceptible to rainfall. To prevent snow or raindrops from blowing into the house through the front doors, they make a closed exit to the terrace.
Correct arrangement of the roof over the terrace
Open terraces are built without a roof. The roof can be a collapsible or retractable awning. Such a light canopy will protect the resting place from the sun and light rain. Closed verandas with sliding glass walls allow you to equip a cozy room on the roof of the house. Here you can already install a barbecue, fireplace and other attributes. You can relax on the glazed veranda in any weather. When the heat comes, the walls simply move to the side, opening the way for fresh air. Above the closed veranda, they equip a light plexiglass roof or hang an awning.
The most difficult roof is for a fully enclosed terrace. That is, a full-fledged insulated veranda with solid walls is obtained on the roof of the house. Heating can be extended inside such a room, and it can be used as a living space. Fully enclosed verandas have an impressive weight. Before erecting them, you need to accurately calculate the loads falling on the foundation and walls of the house. The roof of a closed veranda and a residential building is a single covering. If the extension is carried out on top of the finished building, then usually the entire roof has to be dismantled, after which a new rafter system is installed and the roof is equipped.
Flooring
The choice of material for covering the terrace floor is huge:
- As always, the tree comes first... Decking flooring looks beautiful. The material is in demand for any design, it is easily processed during installation, and special impregnations increase its service life. The most demanded is the decking made of larch. The popularity is based on the resistance of wood to rotting in conditions of high humidity. A floor made of such a terrace board will last for more than a decade. Wealthy owners of private houses prefer exotic wood planks. The appearance of such a floor is striking in its beauty, but the cost of the material sometimes goes beyond reason. A budget option for a terrace floor is a softwood board. Pine is the most commonly used. Wood of this species does not tolerate dampness well. After a couple of years, the board will start to rot in places. Special impregnations help to extend the service life of the material. The advantage of a terrace board is its low weight. Wooden flooring is the only option for arranging a light terrace on the roof of a frame building.
- Ceramic tile has a lot of advantages, but a fly in the ointment spoils honey. An important disadvantage of the material is its large weight, which creates an additional load on the supporting structures of the house. In addition, experts often equate the cost of laying with the price of the tiles themselves. When choosing such a terrace covering, preference is given to tiles with an anti-slip surface. Rough or corrugated texture prevents slipping after rain.
- The open terrace floor can be used as loose natural materials such as pebbles or colored rubble... Natural stone is in harmony with green spaces, and looks spectacular. A huge drawback is the large weight of the material. Such a floor can only be organized on a house with a strong foundation, brick walls and concrete floor slabs.Another disadvantage of flooring is its frequent maintenance.
- Flooring made of rubber on terraces is rarely used... Such material is appropriate to use if the place is reserved for the gym.
- Rooftop terrace looks great in urban environments with lawn... The resting place takes a person to a corner of untouched nature. The lawn requires constant maintenance, but the result is worth the effort.
- Gaining great popularity composite materials... They contain natural and artificial ingredients. Composite board completely imitates natural wood. Polymer additives increase the service life of the decking, and are safe for humans.

The material for the terrace floor is usually chosen based on the price, which is not always correct. The main thing is that it is lightweight, resistant to environmental influences and not slippery.
Terrace design
The terrace serves as a resting place. Here you need to create a calm atmosphere close to natural conditions. Of course, not everyone can get a lawn. Flowerpots with decorative vegetation will help to bring the feeling of being in nature as close as possible. Mini-flower beds with flowers, weaving lianas, a decorative pond with a fountain, etc. are welcome. In flowerpots, you can even plant low-growing trees, shrubs, and girlish grapes.
Furniture items woven from natural vine look spectacular on the terrace. These can be benches, chairs, armchairs or sun loungers. You can even hang a hammock, and above it organize a lattice canopy, braided with lianas. There are a lot of design options for a roof terrace. It all depends on the desire and financial capabilities of the owner.
