Glaces for a soft roof: overview of cornice and end bar

To ensure longevity and efficacy in the installation of a soft roof, it is essential to comprehend components such as cornices and end bars. These components are essential for maintaining the structural integrity and weather resistance of your roof in addition to making it look better.

The ornamental molding that runs along a roof’s edge is referred to as a cornice in the roofing industry. The cornice has functional uses in addition to aesthetic ones. It aids in directing water away from the structure, guarding against water damage and guaranteeing effective management of snow and rain runoff.

However, an end bar—also referred to as an edge strip or edge trim—is necessary to secure the roofing material’s edges. In addition to giving the roof’s perimeter a tidy finish, it helps shield the edges from weather-related deterioration.

It’s important to select the appropriate materials for your end bar and cornice. These parts are usually constructed from PVC, aluminum, or galvanized steel. You can select a material according to your needs and budget because each one has unique benefits in terms of cost-effectiveness, durability, and upkeep.

Careful planning and close attention to detail are necessary when installing cornices and end bars. These elements must be installed correctly in order to effectively divert water and safeguard the roof edges. Consulting with roofing experts can ensure that the job is done correctly, improving the look and functionality of your soft roof, whether you’re installing new components on an existing roof or replacing them.

The main thing about the soft roof

An arrangement of flexible tiles creates a soft roof. Sheets (hounds) of this type are made of fiberglass, modified bitumen layers, and a decorative layer of basalt crumbs (granulators).

The hounds can be combined to create a drawing that resembles a tile. Manufacturers supply flexible roofing material in a variety of styles and hues.

The roof pie made of flexible tiles has unique qualities. It is made up of the following components:

  • Vapor barrier film.
  • Rafters.
  • Insulation.
  • Hydro-light membrane.
  • Contact.
  • Chat.
  • Oriented stoves (OSP).
  • Lining carpet.
  • Roofing.

In contrast to a roof composed of different materials, like corrugated board or metal tiles, a soft roof design is integrated into a continuous base and lining carpet.

Oriented stoves (OSP-plots) and moisture-resistant plywood (FSF) are utilized as continuous bases. They are necessary for the even layering of flexible roofing material.

On a continuous base, a lining carpet is installed. It acts as an extra leveling layer for flexible tiles and shields the roofing cake from the effects of rain and talus snow.

The construction of a roof pediment and cornice comes before installing flexible tiles. This is accomplished by installing endoons on the pediment and cornice strips on the cornice. We’ll talk about them later, along with the fact that they exist and how to mount them properly.

Carnish bar: review and installation

Metal corners that are fixed to the roof’s cornice are called cades for soft roofs. More specifically, the first launch board is situated beneath a continuous base and lining carpet. Cades are necessary to give the cornice a lovely and tidy appearance while shielding the crate from wind and precipitation.

Types of cornice planks

For a soft roof, there are two kinds of cornices:

  • Steel strips with polymer coating. Such a coating protects the product from burnout in the sun, corrosion and mechanical damage for many years. As for the guarantee and the service life of the planks, then each manufacturer has different.
  • Steel strips with a sprinkle from basalt granulatory. If you want the slopes and cornice to be made in the same style, then the option with stone sprinkling is a great solution.

The dimensions of the cornice planks

The following specifications are typical for soft roof cornices, though they vary depending on the manufacturer:

  • The width of the upper shelf – 100 mm.
  • The width of the lower shelf – 65/70 mm.
  • The width of the hooked edge – 10 mm.
  • Planes length – 1.25-2 m.

Generally speaking, the cornice strips’ inner angle is 120 degrees. You can straighten and make the corner more ridiculous in order to arrange the bar’s steeper roofs.

Installation of cornice planks

For soft roofs, cades are installed after gutter installation but before the roofing material is laid, with a continuous base and lining carpet. The bottom edge of the cornice strips should sit atop the gutter’s edge and be 40 mm from the mounts.

Take the following steps to install cornice strips:

  • Install the cornice bar on the first launch board. Use the hazardous nails with a wide hat for this.

Using a 150 mm step, cut the nails in a checkerboard pattern. Retrench 25–30 mm from the bar’s fold site at the same moment. As a result, fasteners won’t be visible once you install a flexible tile. 10–20 mm is the distance from the bar’s upper edge.

  • Install the rest of the strips with an overlap equal to 30-50 mm. At the same time, do not allow fasteners fixing two planks at the same time. Make the joints as indicated in the second image.

Cut the lower shelf of the lower bar as indicated in the picture for dependable docking. Next, place the components inside one another.

Granulatory coated cades have unique areas that are 5 cm wide and devoid of ornamental sprinkles. This makes connecting such strips with one another convenient.

Installation of cornice planks at the outer corners of the roof

The cornice strips are placed on the outer corners of the soft roof if it is hollow or tent-like. Two strips joined in a specific manner are used for this. We explain the process to you:

  • Take the cornice bar and mark 3 cm from its edge. Then draw a line across the lower shelf.
  • Make incisions along the marked line and at the place of fold of the bar. Bend the resulting petal down 90 °.
  • Attach the bar to the cornice corner. Mark with a pencil the place in which it comes into contact with the rib of the roof. Then draw a line connecting this point and angle of the resulting cut.
  • Attach the bar again to the cornice of the cornice and bend along the marked line. Also bend the bar along the cornice line. Fasten the resulting design on the cornice with hazardous nails.

  • Take the second bar, attach it to the cornice and put it on the first. Make marks where it is in contact with the roofing edge. Between the marks, draw a line. Cut the bar along the drawn line.
  • Attach a trimmed bar to the cornice and fix it with nails. Connect the lower shelves of the strips with a rivet.

Installation of cornice planks at the inner corners of the roof

You must dock two cornice strips on the soft roof’s cornice if it has internal corners, or yendovs. To accomplish this, take the following steps:

  • Take the cornice bar and make a cut at the place of its fold. Its length should be approximately 20–25 cm.

  • Bend the edge of the upper shelf a little upstairs. Cut the petal from the edge of the lower shelf and bend it in the same way. You should get a design, as in the photo below.

  • Attach a cut bar to the cornice, at the junction of two slopes. Fasten it with fidget nails.

  • On the other bar, also make a cut at the bending site. Cut length – 20-30 cm. The upper shelf must be bent up, and the bottom is completely cut off. Install the resulting structure on top of the already installed bar. Do this with the help of ruffled nails.

After installing the cornice strips all the way around the soft roof’s cornice, move on to installing the end planks.

Parts: review and installation

Metal corners known as end strips are fastened to the ends of the roof. They give the ends a finished look and shield the crate from rain. The small side of the thin strips for a soft roof keeps the hounds from raising to the side when a strong wind is present.

Types of end planks

Similar to cornice strips, there are two variations available for end strips on a soft roof:

  • Polymeric steel with a polymer coating. Such strips for many years have not been covered with rust and scratches. They also retain their color for a long time.

  • Ending trims made of steel with stone sprinkling. Depending on the installation site, end strips for the soft roof can be right and left. The right is mounted on the right end board, and the left on the left. For convenient installation, such strips have a strip without granulatory.

The dimensions of the end planks

The following are the specifications for the soft roof’s end strips:

  • The width of the upper shelf – 100 mm.
  • The width of the lower shelf – 70/65 mm.
  • Bort width – 15/20 mm.
  • The width of the hooked edge – 15 mm.

Installation of end planks

Cornice installation is followed by the mounting of file strips for soft roofs. You decorate one end board at a time first, then the other. End on the skate after starting on the cornice. The following is a more thorough action plan:

  • Cut the first end bar. This is necessary to create an aesthetic joint with a cornice bar. To do this, cut part of the upper shelf. How to do this is shown in the photo:

Cut the "petal" on the bottom shelf after that. Specifics in the picture:

After that, bend the "petal" 90 degrees inward. Next, position the end bar on the end board and slide it into the cornice bar that is already in place.

You ought to receive a tidy and dependable joint.

  • Fasten the first end bar on the end board. Use fidget nails for this. Cut the fasteners in a checkerboard pattern with an interval of 120-150 mm. At the same time, retreat from the fold of the bar 10-15 mm. This is necessary so that after installing flexible tiles, nails are not visible.

  • Fasten the rest of the end strips. Do this with a 30-50 mm overwhelming.

After finishing the first end board’s end strip installation, move on to the other. For this, utilize the algorithm provided above.

Connection of the end planks on the skate

Attach the end strips for the soft roof on its skate after both ends have been registered. They have to be cut to accomplish this. The steps are as follows:

  • Mark. Attach the first end bar to the left end board and mark on the lower shelf the place where the roof is located. Spend a vertical line in this place.

  • Cut the bar for the left end board. Cut it along the marked line. You should get a diagonal incision. Then retreat 10-15 cm from it along the fold of the bar and make a vertical incision on the adjacent upper shelf.

Another semicircular should be made on the lower shelf with a diagonal cut. It should be situated 10–15 cm away from the diagonal incision and continue vertically from there. As a result, you remove everything unnecessary and obtain the end bar that is the right length.

Make a cut along the side that is 10 to 15 cm long on the bar’s upper shelf. A rectangular "petal" that bends inside should result.

Slice a line through the side. The diagonal section on the lower shelf ought to continue there. Consequently, you will make a semicircular cut to remove a portion of the bar. Get a design like the one in the third picture.

  • Put the cut bar on the left end board. Make it so that the "petal" covers the right end board.

  • Cut the bar for the right end board. To do this, first make an incision across the upper shelf, and then along the bend of the bar. You should get a bar with a short upper and long lower shelf.

Then, on the longer, lower shelf, cut a semicircular petal. Slice off the remaining portion. Get a design like the one in the third picture.

  • Install the resulting bar on the right end board. Cook it with the bar on the left end board. Then secure both elements with yellow nails. You should get a beautiful and neat joint.

Install the flexible tiles after installing the cornice and end strips for a soft roof. See the article "Installation of flexible tiles with your own hands: step-by-step briefing on work" for instructions on how to accomplish this.
