The center of country life can be called a patio. This is a continuation of the house, depending on the design features (open or closed type) allows you to gather households or guests under your roof. The climatic conditions and purpose of the annex determine the construction of the structure. Usually it serves as a place for rest in the warm season, and in winter it is used as an auxiliary room. Of course, if you wish, you can warm it and arrange a greenhouse, a library, etc. In this article, we will talk about how to build a patio roof.
- Achieve the ideal harmony will help the use of materials from which the residential real estate was built;
- The wooden house settles down within 2-3 years, therefore to make extensions before the expiration of this term it does not follow;
- Patios are arranged in such a way that there is access to it from the inner room (kitchen, corridor);
- It is desirable that the foundation and the roof for the main structure and patios are unified. If the annex is erected later, the frame is supported by columns of brick, and the roof is made with a large slope;
- The length of the structure usually corresponds to the wall parameter, the width does not exceed 8 feet.
As a rule, the roof is finished with the same material and in the same color solution as the main structure. This approach will avoid disharmony, provide a visual continuation. The one-deck roof for the patio most often has a steep slope, which allows the snow masses falling from a thaw at home to not accumulate on the roof.
The construction of the roof is carried out using lumber. To increase the service life of the finished frame, all wooden elements are treated with impregnations. Means provide protection against moisture, fire, damage by woodcarvers.
For security reasons, the roof slope is organized away from the entrance. In winter, this will prevent the unpleasant consequences associated with the descent of snow.
The pitch of the rafters and the battens is determined by the material to be coated. Particular attention deserves the joint of the roof of the patio and the wall of the house. It must be securely isolated, otherwise, leaks can not be avoided.
Do not neglect and waterproofing, especially if the structure is covered and it will be used until late autumn, and in winter to use as a storage facility. Next, will be given useful advice on how to make a roof on the patio.
The slope of this type of roof should far exceed the minimum indicator – 12-15°. The supporting structure, including rafters, racks and other elements, is made of boards with a thickness of at least 2 inch.
The construction of the roof begins with the definition of the side of its slope. Create an additional height will help an additional frame, which is installed on the top harness of the future extension.
It is made of bars 23.5-31.5″ in height or more, depending on the planned slope. The upper horizontal beam is fixed to the wall of the main structure by means of anchor bolts. In the same way, the frames of the frame are attached. All the details of the construction are fixed to each other by hardware or metal corners.
In the received rectangle spacers are inserted every 20 inch, they will strengthen the bearing capacity of the roof. To increase the rigidity of the rack, strengthen the braces set at an angle of 45°.
In the bars of the binding at the fastening points of the rafters, cuts are made for their installation.
The upper ends of the rafters are installed on the run (horizontal beam), which runs along the wall of the house and is connected with the frame pillars of the patio. The underside of the supports is inserted into the prepared grooves of the strapping. Fastening of wooden elements is carried out by means of nails or screws.
The step between the elements of the rafter system is determined by:
- Total length of the roof;
- Angle of inclination (the larger it is, the more often longitudinal supports are used);
- Length of rafter legs (high index reduces the step between elements);
- Choice of roofing material (for a light material the distance between the rafters can be maximum).
Recommended step of the experts depending on the roofing material:
- Ceramic tiles – up to 14″;
- Metal tiles – 23-35 in;
- Ondulin – 24-40 in;
- Slate – up to 32″;
- Polycarbonate – 40″.
The roof is covered by a crate, which can be solid or discharged, again the horizontal planking is determined by the type of coating. Rolled materials are spread on solid flooring. When installing, it is desirable to cut the material in such a way that its edges on all sides of the roof are more than 4″. Later they will be bent and nailed with special nails.
Before laying insulation or roofing material in the area of the connection between the roof and the wall of the house, a metal apron must be installed. Here you can also use additional elements (internal corners), corresponding to the roofing.
Such parts will provide reliable protection against possible leaks, they will not create problems when fixing the same type of materials and give the structure a complete look.
Roof gutters on the patio
An important element of any structure is the system for removing rain and meltwater. The patio and the house should have separate gutters. The matter is that the existing system can not cope with its purpose in connection with the increased area.
It is sufficient to use standard U-shaped troughs. They can be covered with a net that will prevent the ingress of foliage, branches and other large debris. The main thing is that the diversion should be carried out as far as possible from the foundation of the house. Ideal option is the outlet of the drainpipe in close proximity to the storm sewer.
