Soft roof Ruflex. Materials and accessories. Installation of the roof base and lining carpet. Installation of metal cornice strips and tiles

Soft roof Ruflex has recently become increasingly popular, mainly due to the ease of installation and the attractiveness of external characteristics. Flexible roofing tiles are applicable both for the installation of new and for the reconstruction of old roofs.

The main feature of this material is the possibility of its use on roofs of any shape, configuration and complexity in general, while ensuring 100% tightness and excellent appearance.

In addition, flexible tiles have high noise-absorbing qualities, in contrast to such a structure as roll roof.

Roof soft Ruflex is a flat sheet of small size with figured cutouts along one of the edges. The top layer of the tile is covered with coarse-grained basalt dressing, which provides a variety of colors and protects the material from climatic and mechanical influences.

Over 60% of the lower part of the shingles is usually covered with a layer of self-adhesive frost-resistant bitumen-polymer mass, which is protected by a siliconized easily removable film.

The main part of the components that are used in the manufacture of soft tiles is almost always the same:

• modified bitumen;
• fiberglass or polyester;
• sprinkles and other materials.

Materials and accessories for soft tiled roofing

To install a soft tile roof, you will need the following set of tools:

• ridge-cornice tiles;
• lining carpet;
• valley carpet;
• drainage system;
• ventilation elements;
• nails;
• glue;
• metal slats.

Installation of a roofing base for flexible tiles

Often, oriented strand board (OSB), moisture-resistant plywood, or solid flooring made of edged or tongue-and-groove boards is used as a base for flexible tiles.

Base properties to be achieved:

• dryness - the maximum moisture level is 20% of the dry weight of the material;
• rigidity;
• evenness - differences in height should not exceed 1-2 mm;
• strength - the calculation of a roof made of soft tiles should provide for such a thickness of the material, which will take into account the presence of lathing, the slope of the roof slopes, snow load and other factors.

Ruflex soft roof is mounted according to the following rules:

• Plates are mounted in a checkerboard pattern, providing displacement of vertical joints.
• Leave between the plates the necessary gap of 3-4 mm to take into account the linear expansion of tile sheets with fluctuations in temperature and humidity of the surrounding air. The absence of this gap can lead to deformation of the base of the roof.
• The base plates are laid across the supports parallel to the eaves.
• A solid base is fixed with an indent from the edge of 10 mm and with a step of 15 cm with self-tapping screws 2.5 times the thickness of the base, or with galvanized nails with improved fit.
• Provide a distance between the nails inside the plates - 30 cm, along the contour of the plate - 15 cm.

The device of a lining carpet under a soft roof

The roofing cake under soft tiles, in addition to the base, also includes a lining carpet, designed to provide additional waterproofing.

Along with shingles and soft tile roof manufacturers also offer a wide range of additional elements in combination with roofing material.

Roll lining material is laid over the entire roofing surface or in the most problematic places that require increased attention - valleys, roof ridges, end parts, cornice overhangs, junctions with pipes and skylights, and others.

The variant of the underlayment carpet device is selected depending on the length of the roof slope and the angle of the slope.

Ruflex soft roof provides for the installation of a lining carpet, carried out according to the following rules:

• Lay the underlayment on a flat, hard and dry base.
• First, it is laid in valleys and fixed with nails every 20 cm.
• Next, a lining carpet is mounted on the entire roofing area parallel to the eaves, in rows from bottom to top, observing a longitudinal overlap of 10 cm, a transverse overlap of 20 cm.
• The edges are fixed with nails in increments of 15 cm.
• Glue the overlap seams with glue.
• In the valleys, an overlap of 10-15 cm is provided.

Installation of metal cornice strips

To protect the edges of the base from atmospheric precipitation, metal cornice strips are mounted - the so-called droppers, which are installed on the eaves of the roof overhangs and gables.

There are 2 basic rules for the construction of metal cornice strips:

• Planks of this kind are mounted on top of the underlayment carpet, while providing an overlap of 5 cm and fixing the planks with 2-3 nails through both eaves strips.
• Fasten metal planks in a zigzag manner with roofing nails in 10 cm increments.

Installation of cornice tiles and valley carpet

To ensure reliable waterproofing of the valleys during precipitation and snow melting, it is necessary to lay along the valleys above the lining layer, the so-called valley carpet. It is matched to the color of tiles of flexible tiles.

When installing the valley carpet, it is laid out on the roof along the valleys and glued along the edges with glue. After that, the edges are fixed with roofing nails at intervals of 10 cm.

Installation of cornice tiles is usually carried out according to the following rules:

• Remove the protective self-adhesive film from the bottom surface of the tile.
• Strips of cornice tiles are laid end to end, retreating from the edge of 1-2 cm.
• The tile is fixed with 4 roofing nails near the perforation points with the following overlapping of the fixing points with ordinary tile tiles.

Installation of an ordinary flexible tile

To avoid differences in color shades, tile tiles are mixed from 4-5 packs. On the same roof, it is not recommended to use tiles produced at different times.

Advice! Among other things, it must be remembered that the minimum slope of a roof made of soft tiles is 12 degrees.

The rules for installing an ordinary flexible tile are as follows:

• Remove the protective film from the bottom of the tiles, after which it is forbidden to stack them on top of each other.
• Tiles are mounted, starting from the middle of the cornice overhang towards the end parts of the roof.
• Glue the first row on a structure such as soft roof standard, so that the petals of ordinary tiles overlap the joints of the flexible cornice tiles and the caps of nails.
• The lower edge of the first row is arranged no higher than 1 cm relative to the lower edge of the cornice tiles.
• Fix with 4 roofing nails slightly above the edge of the tile groove, about 2-30 mm from it, as well as along the edges.
• With a slope angle of more than 45 degrees, the tile is fixed with 6 nails - two additional nails are nailed in the upper corners of the tile.
• Each subsequent row is laid in such a way that the location of the ends of the petals is ensured at the same level or slightly higher than the cutouts of the tiles of the previous row, and the nail heads are also closed.
• The bottom edge of the tile should not be fastened.
• Care is taken to ensure that the roofing nails penetrate both tiles of both the upper and lower rows.
• Cut the tiles at the ends of the roof along the edge, laying boards so as not to damage the bottom layer, and glue them with glue to a width of at least 10 cm.
• Apply glue to a metal bar and distribute with a spatula.
• The edges of the tiles in the valleys are laid on the valley carpet with an overlap, while leaving a strip of the valley carpet open to a width of approximately 15 cm.
• Cut the edges of the tiles along a line that is parallel to the valley line and glue them.
• Glue is applied to the valley carpet and distributed with a spatula.

Installation of flexible tiles in problem areas

If soft roofing has become your choice, flexible tiles, of which it often consists, are great for laying in hard-to-reach places - at the junction with chimneys, walls, ventilation outlets.

The list of rules for laying shingles at junctions:

• A triangular rail 50 * 50 mm is attached to the crate at the junctions around the perimeter.
• Next, a lining carpet is glued onto it and glue is applied in a continuous layer.
• Mount ordinary tiles up to the vertical side of the junction, over the underlayment carpet and lath, and glue it with glue.
• A strip of valley carpet is glued along the adjacent vertical surface to a height of at least 30 cm, while the strip is led onto the slope by 15 cm.
• Gluing is carried out with a continuous layer of bituminous mastic or glue.
• The junctions are closed with a metal apron or an adjacent bar fixed with dowels.
• The seams between the adjacent surface and the apron are sealed with silicone sealant.
• Then the installation of tiles is continued behind the pipe with an overlap on the valley carpet.
• The outlets of antennas or ventilation of small diameter are sealed with rubber seals fixed to the crate with glue and attached with nails.
• At the same time, ordinary tiles are glued to the protruding skirt of the sealant, after which the flexible tiles are mounted over the sealant.
