This procedure simultaneously solves several important problems: it improves the appearance of the roof, prevents the occurrence of corrosion, and also extends the service life. Properly selected roof paint will help to avoid replacing this important part of the house, which is a much more expensive and troublesome procedure.

When choosing a paint for the roof, several important parameters should be taken into account, among which:

• color spectrum;
• type and composition;
• pronounced anti-corrosion properties;
• resistance to aggressive environmental influences;
• resistance to temperature differences.

Effective painting of the roof of the house can be carried out using the following varieties of paint:

• acrylic;
• oil;
• special paints and varnishes containing components to combat corrosion.

All these types of paints are applicable for the refinement of metal roofs, as well as those that are finished with metal tiles.

An important preliminary step is preparing the roof for painting

Before you start painting the iron roof, you must properly perform its preparation. To this end, work is being done aimed at eliminating pollution, obsolete paintwork, as well as corrosion, if any.

The process of cleaning a metal roof from the above defects consists of several successive stages:

• processing with a special brush with a hard pile;
• soft brush processing;
• washing the entire roof area;
• thorough drying.

If there are cracks and holes on the surface of the roof, it is recommended to process them with a soldering iron.

Particular attention should be paid to areas affected by corrosion. They need to be thoroughly treated with a special tool, and then immediately apply the paint.

Paints for metal roofing

Galvanized Metal Roofs Due to their practicality and accessibility, they are very popular. The best roofing paint in this case is a special acrylic primer-enamel, which has a number of undeniable advantages over oil. The following important qualities are characteristic of her:

• elastic texture;
• good adhesion;
• the ability to use in all weather conditions;
• minimum drying time;
• uniform matte or glossy finish.

High-quality paints and varnishes intended for painting metal roofs are present in the assortment of many popular foreign and domestic brands. Such paints as Tsikrol, Tikkurila, Hammerite, Serebrol, Unikom and others have proven themselves very well.Many of them are distinguished by refractory and anticorrosive properties.

A universal option is rubber paint, which is used for painting galvanized metal, slate roofs, as well as metal roofs. Due to good hiding power and a high degree of adhesion, this paint does not peel at all. Its composition contains high-quality pigments, in connection with which the initial saturated color remains for a long time. The main advantages of rubber paints are:

• elasticity;
• anti-slip properties;
• dirt and water repellent properties;
• safety due to the absence of harmful components in the composition;
• good wear resistance.

How to paint a metal roof

If the goal of your search is high-quality paint for metal, pay attention to aerosol enamelspresented in cans, very convenient to use.

There are three types of paints whose properties differ from each other:

• conventional, designed to give the desired color;
• two-component, simultaneously performing the role of primer and paint;
• three-component, consisting of a special rust converter, primer and the paint itself.

In some cases, it makes sense to use heat-resistant spray paints for roofs, the basis of which are special organosilicon compounds.

Paints in cans are conveniently used if it is necessary to partially update the paintwork of metal tiles.

Paints for black metal roofs

One of the most common materials for creating roofs is ferrous metal.

To effectively paint such a metal roof, it is recommended to use paints characterized by increased elasticity, as well as the presence of special additives against corrosion. These properties are possessed by rubber and acrylic paints and varnishes. It is advisable to avoid oil and alkyd paints, since they are more susceptible to delamination and corrosion damage during operation - this is due to the low level of elasticity.

Features of staining slate coating

Over the years, slate has been used as roofing material. In itself, such a coating is gray and unprepossessing, however, a successful painting can completely transform it.

The advantages of slate are its frost resistance and resistance to temperature extremes, minimal thermal conductivity, water resistance, as well as flame resistance. But he also has a serious drawback: over time, this material begins to become covered with asbestos dust, which carries a danger to humans by inhalation. In addition, microscopic cracks form on its surface, and in the north side there is also a layer of green moss. All these troubles can be prevented by timely painting with high-quality materials.

Currently, there are three main types inks for slateapplied on the roof:

• quick-drying slate enamel;
• water dispersible or acrylic paint;
• liquid plastic.

Special slate enamel is able to create a perfectly smooth and durable coating. It contains high-quality pigments that are not exposed to ultraviolet rays.

Acrylic paints do not allow water to penetrate into microcracks on the slate surface. In addition, with such a coating, water and snow more easily and quickly leave the roof, which, in turn, minimizes stress.

The third option for slate roofs is liquid plastic, which is a synthetic product based on polystyrene or vinyl chloride.Due to its toxicity, this material is not applicable for residential buildings.

The modern market of paints and varnishes offers many options with which you can update the appearance of roofs of various types: from iron to slate. It is very important that the paint properties are fully consistent with the type and characteristics of the roof.
