Even a roof made of the best materials needs to be repaired after a while, so it needs to be cleaned, repaired and painted. This last step is not as difficult and difficult today as it used to be.
Not every type of roof can be painted the same. It all depends on the material from which it is made, how much time has passed since its installation or the last reconstruction.
Currently, on the shelves of hardware stores - a wide range of paints that are suitable for painting roofs from different materials. However, not all paint finishes are created equal. When buying paint, you need to pay attention to the warranty period and weather resistance parameters.
Some experts recommend rubber paints that are highly resistant to external factors, but lose their shine and quickly acquire a yellow tint.
In turn, alkyd ones are susceptible to washing off, they are not recommended for use on galvanized roofs, and paints containing vinyl compounds tend to dry quickly in dry and windy weather.
It is important to paint the roof not only for aesthetic reasons in order to update the facade design, but also, first of all, to protect against harmful factors, such as:
The choice of paint and varnish coating is of great importance, since the strength of the protective coating depends on the correct choice of type, and affects how long the roofing material will last.
Sheet metal (steel) roofs are subject to changes in weather conditions (high temperature, frost, precipitation, wind). Any decrease or increase in temperature will cause the material to contract and expand. As a result, small microcracks form on it, which become larger over time. Cracks are not resistant to water, which leads to metal corrosion after a short time.
Products for painting metal are not always synonymous with paints that can be used to paint roofs. It is important here to remember the intense weather conditions to which it will be exposed. Therefore, it is good to choose paints whose manufacturers mark that they are excellent for the roof, indicating the types.
The most commonly used roof coatings are vinyl and acrylic paints.
They are characterized by good mechanical properties, excellent adhesion to both metallic and non-metallic surfaces. Moreover, the coatings created by this type of paintwork materials are plastic, due to which they contract and expand with changes in temperature along with the roofing sheet itself. The roof does not crack like chlorinated rubber paints. And they retain their original color and physical properties unchanged for a long period of time.
Therefore, for reliable painting, you need to choose a roof paint that will withstand the harshest weather conditions, heavy rain, snow and high temperatures.
Various types of them are used for different surfaces, be it galvanized steel, slate, roof tiles.
In order to successfully renovate a roof, the paint must have the following properties:
Most often, polyurethane paints are recommended for painting, rather than epoxy resins.
And that's why:
The use of conventional metallic paints is strongly discouraged due to the fact that after application and exposure to strong sunlight, they release harmful chemical compounds, not to mention the fact that they can quickly lose their color or, even worse, they will start to rub and scratch metal almost immediately. Over time, these spots cannot be painted over, so that brush marks will not be visible and the appearance of the roof will be spoiled.
Most popular group with very wide properties (low performance paints and very good performance paints). As a rule, they are characterized by durability, wide color palette, and resistance to washing and moisture.
Most often they are available in 10 L and 3 L packs, ideal for galvanized and other metal surfaces. The product is an excellent anti-corrosion paint for roofs and other metal surfaces, in addition it is a primer and at the same time acts as a thixotropic top coat (2 in 1). After painting, it creates a durable matte finish with a high level of durability. It works exceptionally well in changing weather conditions and is resistant to mechanical damage, which is the most important advantage of the product.
When applying it, you do not have to use an additional primer before painting, it adheres perfectly to the surface. It is recommended to thoroughly clean the surface, you can use a special emulsion to degrease the surface.
In order for the roof to remain in its original condition after painting as long as possible, it is necessary to apply the paint correctly. In accordance with the manufacturer's recommendations, it is worth paying attention to the preparation, priming of the roof and the application itself. Some types, for example, do not require additional primer.
Thanks to the use of this type of paintwork, the working time will be reduced.
They have lower performance than acrylics (eg adhesion, biocorrosion resistance, durability, weather resistance). Their greatest advantage is ease of application and smooth coatings.
They are characterized by high resistance to various atmospheric factors (variable temperatures and ultraviolet rays), the process of self-cleaning of the coating from surface impurities during precipitation and very high resistance to water (in various forms). They exhibit hydrophobic properties and good resistance to biocorrosion (development of fungi, algae, lichens). Unlike acrylic, they have lower abrasion resistance and color fastness. Available in a wide range of colors, they are part of the group of facade paints.
The use of phthalic and acidic rubber paints is strongly discouraged for repairing roofing sheets. They are excellent paints that can be used successfully in many other situations. However, in strong sunlight, which is typical of the environment in which the roofing sheet is located, they quickly flake off. They are also characterized by a lack of resistance to changing temperatures, which will lead to their rapid cracking, poor adhesion to the roofing sheet and, ultimately, insufficient protection.
