Mare in the roof: concept, purpose, installation

Often called "mare," roof flashing is essential for preventing water intrusion into a building. Mare stops water from leaking into weak spots by strategically placing itself at important intersections where the roof meets walls or chimneys. Its main function is to divert water away from these intersections so that the building underneath the roof and the roof itself remain structurally sound.

Matrimony installation requires painstaking attention to detail. Mare is typically crafted from sturdy materials like copper, aluminum, or galvanized steel and is shaped to fit tightly around protrusions like chimneys and skylights. For a proper installation, waterproof materials such as silicone caulking or roofing cement must be used to seal any gaps that exist between the mare and the roof surface. This guarantees an impenetrable seal, which is essential in averting leaks that may require expensive repairs.

It’s critical to take local building codes and climate into account when installing mare. Certain areas might have particular demands for installing flashing in order to withstand regional weather patterns, like severe snowfall or rain. Proper installation of mare not only prolongs the roof’s lifespan by shielding it from moisture damage, but also improves its aesthetic appeal.

The term "Mare in the roof" refers to a concept in roofing where additional structural support is added to enhance stability and load-bearing capacity. Its purpose is to reinforce the roof structure, especially in areas prone to heavy snowfall or strong winds.
Installation involves assessing the existing roof structure and strategically placing additional supports or braces as needed. This process helps prevent roof damage and improves overall structural integrity.

The term "mare in the roof" describes a beautiful architectural element that is frequently seen on building pediments. Its dual function of diverting rainwater away from the building’s facade and enhancing the roof’s aesthetic appeal are its dual purposes. To guarantee that "Mare in the roof" endures weather conditions, installation requires precise placement and a strong attachment. This article examines the idea, emphasizing how it can both protect and beautify roofs. It also offers helpful advice on how to install it.

What is a mare

A mare is a component of the roof frame that is used to extend the rafter leg that rests on the brick or block Mauerlat or the upper timber or log strapping of the house in order to create a coronal overhang that is the necessary width.

By using a mare, you can lower the load on the walls and foundation, simplify roof frame construction and repair, and lower building costs.

The reason for this is that:

  1. Rrafts of smaller length are used, so it is not required to provide their departure by the wall plane of 40-100 cm to arrange an overhang. Therefore, they are cheaper, easier and shorter, they are easier to raise upstairs.
  2. Mares are mounted from boards of less thickness compared to lumber for rafters, which reduces the total weight of the roof frame.
  3. Easier to align the overhang line. The error allowed is easy to eliminate by replacing the mare.
  4. If during operation the moisture causes rotting of the support of the cornice overhang, it is much easier to change damaged mares than to repair the rafters.

Mares can also function as decorative elements if they provide the ends of the elements’ decorative shapes by resting on other wood.

The functions of the cornice of the roof

The portion of the roof slope below the wall plane is called the cornice. The cornice frame is made up of rafter legs or their continuation, known as mares. For aesthetic reasons and to keep birds out of the space beneath the roof, boards, regular siding, or special sofits can be sewed in place of the space between the wall and the roof’s edge.

The following are some of the cornice functions:

  1. Protecting wall structures and their decoration from moisture hit during rains, snowfalls, thaws. The appearance of the walls retains attractive appearance longer, structural elements made of wood do not dive and do not deteriorate.
  2. Protection of the blind area from water flowing from the roof. This prevents the penetration of moisture to the foundation, extends the service life of the blind area.
  3. Prevention of moisture penetration inside the roof frame – the cornice bakes protects the rafter system from water spray during oblique rains with a gusty wind.
  4. Protection of windows from direct sunlight. This allows you to maintain comfortable living conditions on the premises on the premises.
  5. Aesthetic completion of the roof structure. Bearing of the cornice hides the “wrong side” of the rafter system, adds attractiveness to the house.

If the roof’s germinum system is not installed, the minimum recommended width of the cornice overhang in Russia’s middle band is 40–50 cm. In this scenario, the design will shield the blind area from precipitation and meltwater that may come through the roof slopes.

Mares are formed from boards measuring 30 x 100 or 30 x 150 mm in cross section. It is important to dry the wood to prevent rot, damage, and knots.

The components that are cut into the size are treated with fireproof vehicles prior to installation. The length of the mare is determined by adding 50 cm to the intended width of the roof overhang when the element is fastened to the rafter leg.

Cadet overhang device

By simply fastening the mares to the rafters installed on the Mauerlat or the upper strapping and the flush cut off with the wall, cadetless removal up to 90–100 cm wide can be formed. Since the mares are an extension of the rafters, the roofing, waterproofing, and crate are installed on them at the same time as the roof ramp is being assembled.

The dropper is mounted after the cornice board has been stuffed along the edge of the overhang.

It is advised to sew the cornice overhang using special elements, such as sofitis or regular fugged boards, after the roof has been arranged. In order to maintain the ventilation of the area beneath the roof, they are affixed with a small space between each element and positioned perpendicular to the wall.

You can get rid of moisture through air circulation, which keeps the rafter system’s components from rotting.

The weight of the roof itself and any snow accumulation will cause the filly to experience increased loads if a roof overhang is installed that is wider than one meter.

These rafter system components—a system of a vertical beam fixed on the building wall, a horizontal beam on which a mare rests, and a slanting that provides the design stiffness—should be covered on the console to reduce the risk of the roof collapsing.

The Mares rest on this Mauerlat console. Consoles can be attached separately, without connecting, or with a horizontal connection along the whole slope.

The design selection is contingent upon the breadth of the cornice removal; for roof lengths exceeding 1.5 meters, the use of consoles with Mauerlat is advised. Also messed up below is the console-equipped cornice overhang.

Installation process

Standard technology is used in the construction of the roof frame, where filly will be used to extend the rafter legs. The filly must be ready once the rafters are mounted on the Mauerlat; their quantity should match the number of rafter legs.

The length of the mare is chosen based on the overhang that the width has planned, and an additional 30 to 50 centimeters is added for fasteners. The size of the mare is determined by the roof project. The longer the mare, the greater the mounting margin required to maintain the structure’s rigidity and prevent the edge of the roof from sinking under load. Use an appropriate cross-sectional board or trim the unit left over after installing the rafters for their manufacture.

The last phase of the roof frame construction involves the mounting of mares:

  1. Prepare a puff template, according to which the required number of elements is cut out. Each of them treat fire -protection composition.
  2. Mareflows are mounted on rafter legs with an overlap of 30-50 cm, leaving the upper ends of the elements. They can be attached with the help of ruffled or ordinary nails. It is important to ensure high -quality clutch for which four nails are used for each node. They are driven two on each side. The ends of the nails should be bent so that the fasteners do not weaken over time. Bolts are also used for fastening.
  3. First of all, the extreme filly on the slope are attached, carefully measuring the sizes. Then the cord is pulled between these elements and the rest are mounted on it. The method is suitable for slopes of a relatively small length on which the cord will not sag.
  4. If the design of the overhang involves the use of consoles, the end of the mare is fastened with a flush with a horizontal beam.
  5. To strengthen the roofing overhang, a frequent or continuous crate is mounted on top of the filly, which adds the stiffness of the structure.
  6. After the roofing device is completed, the cornice is heated.

When fixed with sofit, siding, or boards, the cornice maintains its aesthetic appeal, prevents moisture from getting into the rafter system, and doesn’t obstruct natural roof ventilation.

There are two ways to detect an overhanging cornice:

  1. Diagonal strips are mounted directly along the filly;
  2. Horizontal supporting bars are preliminarily installed on the building of the building to create a box and attached elements of the binder perpendicular to the wall.

During the last stage, the wind corner is installed along the slope and the end portion of the cornice box is stitched. These components give the roof a finished appearance, shield it from drops during oblique rains, and prevent strong winds from blowing the structure.

Anyone wishing to improve the looks and functionality of their roof must comprehend the idea of a "mare in the roof." This architectural element, commonly referred to as a pediment, is located above a building’s main structure and serves both functional and aesthetic purposes.

Above all, a mare in the roof adds a unique visual element that frequently improves the building’s overall appeal and character. It can make a major contribution to the architectural style, whether it is classical or modern, giving the roofline a more polished and well-balanced appearance.

Careful preparation and execution are necessary when installing a mare in the roof. In order to guarantee a proper fit and alignment with the current roof structure, it requires precise measurements as well as structural considerations. It is frequently advised to hire a professional installer to get the best results and to guarantee durability against weather conditions.

Homeowners and builders can improve the practicality and visual appeal of their roofs by making educated decisions based on their understanding of the function and installation procedure of a mare in the roof. This architectural element is still a classic choice in roofing design, regardless of whether it is used for new construction or renovations.
