Siding for decoration is a material that is affordable in price and attractive for its ease of installation. Many owners of private houses seek to buy siding. Experts say that it has no problems in operation: frost-resistant, resistant to deformations, etc. But there are still siding issues, and we propose to consider them.

Surface curvature

This material has a high coefficient of expansion in heat, and under the influence of temperature, the lamella increases proportionally to the original dimensions, both in thickness and length. So it turns out that over time, the surface curvature effect occurs. Moreover, a few hot days are enough for siding problems to arise, and the surface becomes skewed. Do not tightly connect the lamellas at the corners. When the lamella expands, it rests against an adjacent element, which in turn acts similarly. And as a result, bending of the skin occurs.

Loss of color

Trying to save money, the owners buy the material cheaper. They think that there is no difference, and the types of siding and the different prices for them are a marketing ploy. And there is a difference! The lack of coloring pigments leads to the fact that in the sun, it fades faster because there is no UV resistance. On light material, this is less visible, but on more saturated colors, it is noticeable.

Mold on siding

If mold appears on your vinyl, this indicates a factor of dampness and moisture. Vinyl is a product of organic chemistry. This means that the possibility of the appearance of microorganisms is very likely. Plastic swells, depressions appear (invisible to us), and fungi and mold begin to multiply on them. To fix the problem, wash more often with disinfectant solution.

Siding turns green

It is also the result of increased humidity and dampness. Instead of microorganisms, mosses multiply on the surface, and the beautiful, shiny surface takes on a greenish color. Thorough rinsing with a special agent will correct the situation.

Waves on siding

It happens that after a couple of years, waves appear on the siding if initially there were violations during installation. The fact is that the lamellas have a perforated section for their attachment. And during installation, it is necessary to insert a nail or self-tapping screw only into the center of the oval hole. The displacement of the attachment down, up, or on the sides does not allow uniform expansion of the lamellas when the temperature rises. They push against the edges, creating tension, and the sheathing takes on a wave pattern, negating the aesthetics and life of the material.

Fire risk

The main and probably the only real danger associated with the use of façade-hinged systems is the likelihood of fire. This problem is especially relevant for a façade that has a ventilated layer. The thrust in the ventilation gap will fan the fire and quickly spread it along the wall. Replace your siding with a fire retardant one. The most fire-resistant is fiber-cement siding, which not only does not catch fire but can even survive local impact without any extraordinary consequences. Metal siding is also considered non-combustible, but due to the effects of fire, it will lose its original appearance, lose its protective layer from corrosion and become unusable for further use.


Often siding deteriorates due to moisture. The solution to the problem is to change the current one to vinyl. It contains polyvinyl chloride. The material is recognized as resistant to moisture, but at the same time, it cannot withstand mechanical damage. The service life of vinyl siding is no more than 20 years.

Since most decks are attached to the siding, you must keep in mind that changing your siding affects your deck too. They are very closely built therefore you must pay extra attention to the process of changing your siding. The best thing you could do is work with professional deck builders so that you get the siding and the decking that you need.

Final word

To have complete confidence that the façade material will not fray and break in the coming year, you should assess the impact factors correctly. To choose classic siding, you should consider the level of humidity - when high, select materials that do not contain metal components. The price is also essential - the best option would be the middle price category. Do not neglect the temperature factor since large temperature drops are constantly observed in your region. It will help if you choose a siding that will not contain either wood or metal.
