Frequently asked Questions


How quickly does Keramoplast fade?

Keramoplast does not fade. The sheets of our roofing material are painted throughout the entire thickness by the best light-resistant European mineral dyes that do not fade in the sun. There is a lifetime guarantee for color preservation.


What is the content of Keramoplast?

Our roofing material consists of a polymer and ceramic composition.


What are the similarities of polymeric sand tiles and Keramoplast?

They have nothing in common. These are different roofing materials. They have different content, different production technology, different structure and thickness.


Terms of Keramoplast shipping to consumer.

The price indicated on the website and in the price lists is the selling price at the plant in Kherson city. Shipping of roofing sheets and accessories (wind boards, ridges, roofing nails, protective caps) is carried out at the expense of the buyer. However, the delivery can be partially or completely compensated by the plant. Before you buy our roofing material, please discuss the terms of delivery with our roof manager.


What colors can I order?

At present, the plant produces Keramoplast roofing material in 4 main colors: black, brown, red, and terracotta. On a by-order basis, we can make green, blue, yellow and white ones. However, the price of Keramoplast roofing sheets performed in these colors will be 1.5 times more expensive than in basic colors.


What is the most popular color for a consumer?

It is black. Brown is the second-most-popular. Then goes red. Then – terracotta.


Where can I see and touch Keramoplast?

Open Dealers page of the web-site There, you will see addresses and phone numbers of dealers who sell our roofing material. There you will find the phone numbers of sales department of a plant for the production of Keramoplast.


How to mount Keramoplast during installation?

Keramoplast sheets are mounted on conventional roof sheathing, the same as for conventional asbestos cement slate or Onduline: with nails or screws – the more, the better.

Of course, you can fasten the sheet with 6 nails, but the closer you fix it, the more resistant it will be in extreme weather conditions: in a storm, in gusts of wind, in a large hail, etc.

For more information about installation see Keramoplast the installation instructions on our web-site.


What is the term of service of Keramoplast? Give an example of an object covered with Keramoplast with the largest roof-life.

The plant guarantees 15 years of service life of Keramoplast: tightness, inalterability of shape and color. However, our roofing material will actually serve more than 30-40 years. Now, let’s discuss an example of the object covered with Keramoplast with the largest roof-life.

Today, in Kherson city, the most accessible object to inspect is a house in the courtyard of St. Catherine’s Cathedral on Perekopska street. House walls are made of white Keramoplast sheet, roof – of black roofing sheets. It was built in 1998. The house is 18 years old. It has not changed over the years. Roofing material it is made of the first Keramoplast.

The second public object in Kherson is the roof of “Garde” cafe in Lenin Komsomol Park. The third roof is on a beautiful 3-storey brick residential building in the center of Kherson near Maternity Hospital No.1, opposite the Water-Transport Workers’ Hospital.

There are a number of other serious facilities: cooling towers of metallurgical plants in Donetsk, Ynakiievo and other metallurgical plants in Ukraine. They are already in operation from 10 to 13 years. Other roofing materials cannot stand more than a year in such conditions.


Should I use water barrier when mounting Keramoplast sheets?

As in the process of installation of other roofing materials, water barrier never hurts. When strong storm side winds, sudden gusts accompanied by rainfall occur, the air flow may drive some water in under-roof space.

Therefore, it is better to lay wide sheets of common polyethylene film or other water barrier on roof sheathing before the installation of Keramoplast. Then, even if strong side wind blows water under the roofing sheets (regardless of lateral and vertical overlapping of the sheets), it will roll down this side film.

As a matter of actual practice, Keramoplast is often used without such a film, etc.


What is a capillary groove for?

Capillary groove is needed to save lateral overlap of roofing sheets. Usually, when mounting a corrugated sheet, a lateral overlap in 2 corrugations is made.

The capillary groove replaces one corrugation when overlapping. As a result, when installing sheets with a capillary groove, the size of one corrugation is saved.


How many nails and caps one needs for mounting a single Keramoplast sheet?

At least, you need to batter down 3 nails at the top of the sheet, 3 – at the bottom, and 2 nails – in the middle. This is true at the widest spacing of roof sheathing of 500 mm. This is a necessary minimum. However, in general, there works the rule: the closer, the better.

The best way is to batter down 12 nails per sheet. They are not as expensive, but guarantee stability of Keramoplast under very strong snow loads or hail with icing. They may form a snowdrift up to 1 m high on the roof. In fact, the pressure on the roof sheathing can be more than a ton.

Therefore, spare no nails and screws, when mounting Keramoplast sheets. The roofing material itself is very durable, it withstands much – if only load-bearing construction is able to withstand the same.


What is the cost of 1 square meter of Keramoplast?

Prices can be found in the price list or you can ask managers.


How much will the installation of 1 sq.m of Keramoplast cost? Is it more expensive or cheaper than installing another roof?

It is cheaper than installing Onduline but a bit more expensive than installation of conventional asbestos-cement slate. However, it is much cheaper than ceramic tiles: Keramoplast does not require such strong roof sheathing.


How many nails one needs to mount 1 sheet of Keramoplast?

– 12-20 nails per sheet (roof sheathing with the spacing of 465 mm)
– 15-25 nails per sheet (roof sheathing with the spacing of  350 mm)

Corrugation with a capillary groove:
– 12-20 nails per sheet (roof sheathing with the spacing of  465 mm)
– 15-25 nails per sheet (roof sheathing with the spacing of  350 mm)

Oblique corrugation:
– 9-16 nails per sheet

– 12-20 nails per sheet

Roof tiles:
– 9-16 nails on a leaf

In general, the number of nails depends on the location of the sheet on the roof: fewer nails are used due to overlapping.


What snow load can 1 sq. m of Keramoplast withstand?

Our roof can withstand snow loads up to 1000 kg/sq.m with a spacing of a roof sheathing of 250-300 mm.


Many people, who have the roof covered with metal tile, complain that rain and hail make a terrible noise in the house. How does Keramoplast deal with this?

Pouring rain or falling hail are not heard when the roof is covered with Keramoplast.


What is the weight of 1 sq. m of Keramoplast?

Corrugation – 7.8 kg/sq.m.

Corrugation with a capillary groove – 7.8 kg/sq.m.

Oblique corrugation – 8.9 kg/sq.m.

Cascade – 8.6 kg/sq.m.

Tile – 6.5 kg/sq.m.


What happens with Keramoplast in extreme heat and cold? Is it necessary to use thermal insulation during installation?

No. Thermal insulation is not needed. Keramoplast “works” as thermal insulation itself.


Is it safe to live in a house with a roof made of Keramopolast? Is there any harmful substance in it?

Keramoplast is an environmentally friendly roofing material. It does not contain asbestos, bitumen and other carcinogenic substances.


When installing complex roofs, flexibility of the roof is very important. Can Keramoplast flex during installation? How much?

Keramoplast is very flexible. It can be given any shape – by heating the bending point with a gas burner, bending it and then letting it cool down. At the same time, in our roofing material flexibility is combined with elasticity: this makes it possible to create arched roofs and curved surfaces up to a radius of 4 m without heating.


To assess the durability of the roof, it is important to know the number of seasons of rapid change of temperature it is able to withstand. How many cycles of freeze-thaw is Keramoplast resistant to?

Our roofing material withstands over 100 winter-summer seasons.


A series of extreme hails passed through Ukraine. Huge hailstones literally pierced the roofs. Will Keramoplast withstand bombing of hail the size of a chicken egg?

Tensile strength of Keramoplast is up to 140 kg per square centimeter.
Its flexural strength is 238 kilogram-force. It was evidenced during the events in Mostyshche village  where extreme hail storm damaged the roofs of nearly all buildings except 2 covered with Keramopast.


Can I order a thickened sheet of Keramoplast to increase its strength?

Yes, we can produce sheets 6-7-8 mm thick instead of 4.5 mm (a standard sheet). Thick sheets have strength directly proportional to thickening. With a thickness of 8 mm, roof can withstand static loads of up to 5000 kg/sq.m with a spacing of the roof sheathing no more than 300 mm! To tear an 8 mm thick sheet, it is necessary to apply a force of more than 12 000 kilograms!
The price of thick sheets depends on the individual order.


Is Keramoplast subject to corrosion?

No. Furthermore, our roofing material is resistant to diluted solutions of acids and alkalis and limited concentrations of salt solutions.


When the time comes to change the roof covered with Keramoplast, will there be problems with its disposal?

Keramoplast is easily disposed of. According to EU standards, our roofing material is preferred for use and subsequent disposal of. Keramoplast is easily recycled. For example, it can be crushed, and the resulting mass can be pressed: it is subsequently used for making excellent eco poles for vineyards.


Are all the roofs suitable for using Keramoplast? Is there a limit of the angle?

When mounting Keramoplast, angle of inclination of the roof must be at least 5 degrees with roof sheathing spacing of no more than 250 mm. The smaller the angle of inclination of the roof is – the greater lengthwise overlapping shall be. However, there is one condition: in case of a small angle, it is necessary to treat overlap with a joint sealant.


What is the useful area of the various Keramoplast sheets? How does it differ from the total area?

In case of corrugation roofing sheets, useful area of the roof depends on the angle and size of the lengthwise overlap of the sheet.

See the correlation of the useful area and the total area of Keramoplast roofing sheets in the table below:


Name Total area, sq.m Useful area, sq.m
Corrugation 1.8 1.55
Corrugation with a capillary groove 1.74 1.5
Oblique corrugation 1.74 1.46
Oblique corrugation – 1540 1.34 1.15
Cascade 1.64 1.44
Tile 1.3 1.06
