1. ROOF TYPES
The primary function of a roof is to protect a building or the space below it from water infiltration. When choosing the right roof type, it is essential to minimize the risk of leaks and their damage. In addition to ensuring the waterproofing of a roof, several other considerations play a role, such as insulation, safety (e.g. fire safety), environmental impact, technical possibilities and limitations, aesthetic preference, specific use of the roof, compliance with regulations, budgetary considerations and the promotion of sustainable building.
PITCHED ROOF A sloping or pitched roof is waterproofed by covering the roof with a fragmentary layer of discontinuous materials (roof tiles and slates) that overlap. Roof insulation can be placed along the outside or inside of the roof floor. Another possibility is to insulate the attic floor.
Schematic cross-section of a pitched roof
FLAT ROOF A flat roof does not necessarily have to be exclusively horizontal, but can show - even a steep - slope. It is recommended that each flat roof is given a slope layer with a sufficient slope (±2%) to be able to drain the water to the water drainage point. After installing a vapour barrier, roof insulation is placed on a flat roof: • The most common and recommended installation technique is that of the warm flat roof. Here the insulation is placed on the outside of the roof floor. • With a cold flat roof, the insulation is placed under the roof floor. This technique is no longer recommended. • With a reversing roof, the insulation is placed loosely on top of a sealing layer and the use of a vapour barrier is not necessary, since that function is taken over by the sealing layer. A ballast layer must be applied on top of the insulation.
Schematic cross-section of a warm flat roof
The waterproofing of a flat roof is done with a continuous waterproof membrane of bituminous, synthetic, liquid or metal nature. • Bituminous roofing is applied in 1 or more layers of polymer bitumen (APP or SBS) and is always reinforced with glass fleece or polyester. An oxidized bitumen can possibly be used as a base layer. • Synthetic sealing is applied in one layer and is based on elastomers (EPDM), thermoplastic elastomers (TPE) or plastomers (PVC). This with or without reinforcement and/or caching at the bottom of the sealing layer. • In addition, there is the use of liquid seals (PU, SMP...) or metal roof seals.

2. INSTALLATION OF BITUMINOUS FLAT ROOF
2.1 INSTALLING INSULATION ON A WARM FLAT ROOF A warm flat roof is the most recommended and used insulation method and means that the insulation is placed on the outside of the roof floor. The advantage of this method is that the roof structure is located under the insulation layer, which significantly reduces the likelihood of cracks and fissures and therefore also leaks. The insulation layer acts as a heat buffer: the heat from the sun is absorbed during the day and released when night falls, which is advantageous for energy consumption. To apply an insulation layer, a vapour barrier is placed on top of the slope layer. The vapour barrier prevents condensation moisture from entering the insulation material. Insulation is mainly glued with synthetic cold adhesives (1C PU, 2C PU...) but can also be glued with a bituminous cold glue. On top of the insulation, the waterproof finishing layer is applied.

Prime the substrate if necessary (see the manufacturer's instructions for roof sealing/vapour barrier). Start gluing the insulation panels at the furthest point from the roof access point and work towards the access point to avoid walking on the bonded panels. After applying the adhesive foam to the insulation panel, wait for 2-3 minutes, then apply the insulation panel to the flat roof within 5 minutes and press it firmly into the grooves. Do not walk on the panels for at least 2 hours after pressing. If the insulation panels have shifted or been moved during the curing time of the adhesive foam, reapply the adhesive foam to ensure good adhesion.

Apply in grooves of at least 30 mm diameter every 20 cm. In corners and edge areas of the roof, at least twice as much adhesive foam must be applied. Maximum unevenness between insulation and substrate is 1 cm. For uneven surfaces, grooves of at least 50 mm diameter must be applied, so that 40% of the surface is covered after pressing the panel on the surface. The consumption of the adhesive foam or the correct number of adhesive grooves is determined by EN 1991-1-4 in which region, roof surface, building height and location on the roof play a role.

2.3 COLD BONDING OF ROOF MEMBRANES A bituminous seal of a flat roof consists of one or more layers of finishing, where the top layer consists of polymer bitumen and a reinforcement of polyester. The finishing layer must be provided with a certificate of suitability for use. The bituminous seal can be attached via, for example, flame welding. However, an easy and fire-safe way is to use a bituminous cold glue in which the finishing layer is glued to the substrate.

3. PROTECTION OF BITUMINOUS FLAT ROOF
Although bitumen roofing offers many advantages, it is important to know that bitumen is naturally less resistant to UV radiation. Over time this can lead to damage to the bitumen layer, which increases the risk of leaks. To give bitumen additional advantageous properties, polymers are added. For example, a plastomer (APP) can make the bitumen firmer and offer better UV resistance. Adding elastomers (SBS) makes the bitumen more manageable, even at colder temperatures, and improves peeling resistance. However, it is important to note that the UV resistance is still not optimal. To improve UV resistance, a mineral protection layer with slate flakes or granulates (available in different colours) can be integrated, or a ballast layer can be added, consisting of gravel, slate or roof tiles.
IMPROVED OPERATION WITH A REFLECTIVE COATING LAYER An alternative approach is to apply a reflective coating layer on top of the bitumen roofing. In addition to protecting the bitumen layer, this type of roof coating offers additional advantages. The sunlight is strongly reflected, so that the roof heats up much less. This can lead to a reduced cooling requirement in the summer. In addition, the operation of solar panels placed on such a roof will provide an improved efficiency of up to 15% and extend the life of the photovoltaic installation. This leads to increased energy generation and therefore additional savings.

4. RENOVATION OF BITUMINOUS FLAT ROOF
If, despite protective measures of the bituminous roof, wear and/or bladders occur, the roof must be repaired to extend its lifespan. A first option is to apply a renovation layer that has a nourishing and restorative function. If the wear has gone too far, it is necessary to apply an additional layer of bitumen. In both cases, the method is the same: • Clean the existing surface so that it is clean and flat • Repair bladders by cutting them open, drying and sticking them, shut and repair possible cracks and fissures with Pararoof Super • Application of a bituminous primer (Pararoof Quick Primer) • Apply a renovation layer (Pararoof Renovation) or a new bituminous layer and seal with Pararoof Bitumen or Pararoof Super If there is no insulation layer yet, it can still be installed during the renovation of the flat roof (reversing roof method).

1. MOISTURE, A SOURCE OF CONCERN
CAUSES OF MOISTURE PROBLEMS Moisture problems in buildings can be a significant source of concern. The problems vary in origin and severity. Understanding the different causes is critical to effectively addressing and preventing damage to buildings. Common causes are rising damp (p. 18), infiltration of rainwater (p. 21) but also: Building moisture is the moisture that remains in building materials after the construction period. It is estimated that up to 5,000 liters of moisture remain in the construction of a family home. Internal condensation: moisture transport occurs under the influence of a vapour pressure difference between the inside and outside of a building. When the moist air comes into contact with a cold surface in a building element, there is a risk of internal condensation. Surface condensation: by cooking, showering, moisture released by plants... vapour is created in the house. Depending on the temperature, the air contains a percentage of water vapour. Once 100% relative humidity is achieved, the vapour will condense and surface condensation will occur. Porous materials absorb moisture from the ambient air, a phenomenon known as hygroscopy. Soluble salts: salts in building materials easily absorb water. When dried, they can cause cracks and fissures. Leaks and splashing water
HOW DOES MOISTURE MOVE? Moisture movement in porous materials has three main mechanisms: •
Vapour transport In porous materials that are (almost) dry, moisture mainly travels as vapour. This process is slower than the transport of water in liquid form. At high humidity (>70%), the pores gradually begin to fill with water, turning vapour transport into a liquid process.
•
Hygroscopic properties Porous materials can absorb moisture from the ambient air. Hygroscopy is done even without the presence of liquid water. The degree of hygroscopy depends on the number of small pores (<0.1μm) in the material. The more of these small pores there are (for example, with cement), the higher the hygroscopic properties of the material.
•
WHAT IS POROSITY? Porosity is the ratio of the volume of pores to the toal volume of a material. Porosity allows moisture to be transported, which can lead to moisture-related problems. Almost all building materials have some degree of porosity. However, some materials show higher porosity than others. Sandstone is considerably more porous than concrete.
Capillary action Capillary action is the phenomenon when water comes into contact with the surface of a porous material and it is sucked up by the material. The size of the pores determines how far the water can penetrate into the material. The smaller the pores, the further the water can penetrate. The larger the pores, the faster water is absorbed.

2. PROTECT AGAINST RISING DAMP
Rising damp in walls can be a persistent problem in older buildings and can lead to damage to the structure and interior. Buildings built before 1945 were mainly constructed in solid masonry walls, without a waterrepellent membrane being installed at the base of the wall. This practice has led to the occurrence of capillary ascent of soil moisture and the accumulation of salts in the walls, usually to a height of 0.5 to 1.5 meters. Modern buildings, on the other hand, often use masonry with an air cavity and a water-repellent membrane to avoid such problems. However, these construction methods have their own challenges: •
Errors in the installation of the membrane or in the design of the structure. Grounding added later that is above the membrane level, preventing the membrane from functioning effectively.
•
To combat rising damp, injection of a moisture repellent is an excellent and effective solution. Rising damp is blocked at the physiochemical level.

Holes in the wall should be drilled at the correct level, usually in the mortar joint of the wall. The holes should have a diameter of approximately 12 mm and should be spaced about 100 mm apart horizontally. The depth of the drill holes should be about 90% of the wall thickness to ensure even distribution of the injection material. After drilling the holes, it's essential to thoroughly remove dust from the drill holes to ensure optimal adhesion of the injection material. This can be done by blowing or brushing out the drill hole.

3. PROTECT AGAINST GROUNDWATER
The infiltration of groundwater into basements can occur due to negative pressure, or capillary forces can cause groundwater to result in rising damp through the foundations. Both can lead to potential moisture problems. The extent to which groundwater plays a role in the moisture issues of buildings depends on the following factors: • • • • •
Level of the temporary or permanent groundwater layer Circulation direction of the groundwater Water supply flow rate Nature and relief of the soil Nature and properties of the fill between the construction pit and the building
Depending on the conditions of the water load (from low to heavy load), various solutions are possible • • •
The application of an exterior plaster based on cement mortar. The installation of a drainage net and providing the exterior of the structure with waterproof cladding.

4. PROTECT AGAINST RAINWATER INFILTRATION
Due to the porous nature of most common building materials, there is always a risk of moisture problems resulting from rainwater seeping through the walls, joinery, and the roof. Walls and porous roofs can be easily protected by the application of a hydrophobic agent. This technique involves treating porous surfaces to make them water-repellent. This prevents rainwater from penetrating the wall while still allowing vapour transport from inside to the outside. In addition to preventing rainwater infiltration, a hydrophobic agent offers additional benefits, including: • • • •
Increased durability of materials, which limits damage from frost and the effects of acid rain. Simplified maintenance of facades, as dirt washes off more easily, and the likelihood of dust infiltration is reduced. Improved thermal insulation of exterior walls by limiting moisture content. Reduction of green algae formation.

Clean the substrate with Green Cleaner and allow it to dry. Protect the surfaces that are not to be treated. Do not apply in direct sunlight. Apply Parafuge Facade F with a sprayer in one coat or treatment. Start the treatment at the top in a 40 cm strip with a back-and-forth motion. Always allow it to flow in a liquid curtain over the surface, saturating the entire area. Apply Parafuge Facade G with a low-pressure gun, roller or brush.

Manually remove large accumulations of dirt for quicker results. The substrate can be dry or slightly damp. Always shake Green Cleaner before use. Apply undiluted with a brush or sprayer in a single layer. Allow Green Cleaner to work. The cleaning process happens on its own, and the results will be visible after a few days. Do not apply in high temperatures, full sun, or when rain is expected within 24 hours.
