When it comes to ensuring the longevity and resistance of your roof, water-repellent treatment proves to be an essential solution. Protecting against the harmful effects of humidity, mold and bad weather, this process preserves the integrity of your roof and guarantees the watertightness of your home. In this article, we will explore in detail the waterproof roof treatment , its price per square meter and the benefits it offers.
Understanding the water-repellent roof treatment
The water-repellent roof treatment consists of the application of a specific product to the roof of the house. This product creates a protective barrier that prevents water from infiltrating the roof and the development of moss. There are two main types of preventive water-repellent treatments: film-forming water-repellent treatment and beading-effect water-repellent treatment. So how to choose a waterproof roof ? Some explanations.
Film-forming water-repellent treatment
The film-forming treatment forms a preventive protective film on the surface of the roof. This film acts as a shield against bad weather, UV rays and atmospheric pollutants. It is particularly suitable for porous and old roofs which require reinforced protection.
Water-repellent treatment with a pearl effect
The beading effect treatment creates an invisible layer that allows water to slide quickly over the roof surface. This prevents moisture from building up and reduces the chance of moss and cracks developing. This type of treatment is ideal for roofs in good condition that require prevention against humidity.
What price per square meter for a water-repellent roof treatment?
The cost of a roof waterproofing job varies depending on several factors, such as the size of the roof, the type of material, the general condition of the roof, and the geographic region. Larger roofs generally have a slightly lower cost per square meter because the fixed costs are spread over a larger area. In addition, the choice between film-forming treatments and beading effect treatments can also influence the price. It is recommended to request quotes from professionals to obtain a precise estimate based on your renovation project.
General idea of the prices charged in France
In general, renovation prices vary between 10 and 22 euros per square meter, including the supply and installation of the product. Here are the average price estimates based on product choices:
For water repellents with a beading effect: the average price is around 30 euros per liter
For film-forming water repellents: the price is between 30 and 40 euros per liter
Do not neglect the price of moss removal
It is essential to note that before waterproofing your cover, preliminary moss removal is often necessary. Upstream cleaning is crucial in order to eliminate any moss present on the tiles. Indeed, the treatment cannot be effective on a roof invaded by moss. This additional cleaning has an average cost of around €15 to €35 per square meter.
Our advice: to remove moss from the roof, we recommend using a professional anti-moss such as Anti-Dépôt Vert Guard or its concentrated version Anti-Dépôt Vert Guard 500.
In summary, the overall cost of a renovation operation includes not only the price of the product and the intervention, but also any costs linked to prior moss removal/cleaning of the roof. It is recommended to request specific quotes from professionals to obtain a precise assessment based on your situation and your project.
Do it yourself or call a professional?
When it comes to deciding whether to carry out a waterproof roof treatment yourself or hire a professional roofer, there are several factors to consider to ensure long-lasting and effective results.
Requesting the intervention of a professional in waterproof roof treatment guarantees the use of quality products and materials, but also a precise application that takes into account the unique characteristics of your roof. If you use a craftsman, ask for several quotes to ensure the best price.
To reduce the price, it is entirely possible to carry out the work yourself. By carrying out the treatment yourself, you will only pay for the product. To make your cover water repellent, we recommend ImperGuard ST water repellent. This colorless, biosourced waterproofing product deeply protects absorbent roofs against water infiltration. It prevents the development of moss and lichens and avoids damage due to frost. ImperGuard ST can be used on all types of tiles (clay, concrete, etc.) and on slate. ImperGuard ST is available on our website at €50.40 for a 5L container.
Whether for cleaning or waterproofing tiles, don’t forget to obtain the professional equipment generally used by a roofer: a roof ladder, a safety harness, non-slip shoes and a low-pressure sprayer with straps. To remove moss from the roof, avoid using a high-pressure cleaner which can damage the roofing or products that are too aggressive.
Some advice: for all work on the roof, avoid rainy or windy days and above all do the work in pairs for greater safety. Do not also neglect the maintenance of the gutters and the cleaning of the walls and the facade to maintain the perfect aesthetic of the house.
Advantages of waterproof roof treatment
- Prevention of water infiltration: The main advantage of water repellent treatment is its ability to prevent water infiltration. This protects the structure of your roof and prevents damage caused by rain and humidity.
- Increased roof life: By preventing moisture-related damage, water-repellent treatment helps extend the life of your roof, avoiding early renovation and replacement costs.
- Reducing the risk of mold: Mold can be harmful to your health and damage your roof tiles. The water-repellent treatment reduces the conditions conducive to their development.
- UV Protection: Some water-repellent treatments provide protection against ultraviolet rays, which preserves the color and appearance of your tiles.
- Simplified maintenance: A water-repellent roof is easier to maintain, because it prevents the accumulation of dirt on the tiles or in the gutters and makes cleaning easier.
