First and foremost, before winter you need to check the condition of the drainage system, such as gutters, downspouts, couplings, kettles and more.

Generally, gutters should be cleaned at least twice a year. To eliminate barriers in the gutter can DIY to use your own hands, powerful stream of water or a special telescopic rod with cleaning tips in the form of brushes and squeegees. "Gutter systems made of sheet metal are designed so that they are able to withstand the weather. They are therefore provided with a surface layer of polyester paint, which ensures a long life and good color stability. Maintenance of such a system is very simple and economical, "explains Jaroslav Nikodým (et al. Borga). Do not forget to also check whether the gutter joints strong and tight and that the individual parts well connected. Otherwise, the water could overflow or leak, and thereby commit damage to the facade of the house. During harsh winters and freezing it pays to install and frost gutter systems.

In the case of roof tiles make particularly metal sheet elements, which occur at the lateral connections, chimneys, skylights and the like. Clean them to make them nevrstvily dirt and could post them seamlessly to drain the water. In contrast, light covering, which usually occurs on flat roofs require from the cold any special care. "Light coverings are usually equipped with special water groove, which prevents the ingress of rainwater and snow gaps in the overlap of individual profiles," explained Jaroslav Nikodým.

An essential part of ensuring the roof before the winter is also installing protisněhových measures. This requirement differs from the site. If the house is located at an altitude of 400 meters, the barriers are not necessary. At a height of 600 meters above sea level, it would be a part of every roof with a slope of over 10 degrees should be snow guards, hooks, snow catchers, sněholamy baffles or snow. In mountainous areas where snow loads roofs considerably more than in the lowlands, it pays to zainsvestovat also protisněhových bags. If the roof ice occurs frequently, it is advisable to use hooks. Sněholamy again installed more often on the edge of the roof, usually above the entrance to the building. Generally, the higher the snow, the greater the amount measures. Helpful is the standard EN 1991-1-3, for example, or snow map Czech Hydrometeorological Institute. Barriers are distributed always evenly over the entire surface of the roof. Proper and functional installation of snow-protection requires fulfillment of strict parameters, so in this case pays to use rather help of an expert.

It is very important to provide wooden roof windows quality coating to protect against moisture and bad weather. With the advent of winter's best to avoid ventilation through roof windows and skylights. Not only that, it facilitates the entry of snow and water into the interior, but also increases the thermal leaks, which could significantly weigh down your purse.
