Roofing materials and types

Roofing comes in several types, each with its own specific advantages. Among the most widely used are modified bitumen, synthetic materials, and innovative solutions like cool roof paint to maximize energy efficiency.

SBS and APP modified bitumen

Modified bitumen is composed of petroleum, fiberglass and polyester. Common types include SBS and APP. SBS (styrene-butadiene-styrene) offers high elasticity and is perfect for cold climates, ensuring flexibility at low temperatures. APP (atactic polypropylene), on the other hand, is ideal for hot climates and resists UV rays well. These performances can be further enhanced by the application of specialized reflective paints, compatible with certain bituminous membranes.

These materials are often applied in strip form, easy to handle and suitable for flat roofs. They offer good durability and require minimal maintenance.

Synthetic materials EPDM and PVC

Synthetic materials such asEPDM (ethylene-propylene-diene monomer) and PVC (polyvinyl chloride ) are popular for their strength and durability.

EPDM is a flexible material, renowned for its durability and tolerance to extreme temperatures. It is often used in flat roof installations. PVC, on the other hand, is more rigid but offers exceptional resistance to fire and chemicals. It is also lightweight, making it easy to install.

These materials are often chosen for their ability to offer excellent long-term value for money.

Innovative solutions like the cool roof

The cool roof is an innovative solution designed to reflect more sunlight and reduce heat build-up on the roof. It's ideal for hot regions where temperature control is crucial.

By exploiting special materials with reflective coatings, these roofs reduce energy costs by keeping buildings cooler. An environmentally-friendly option that helps improve the energy efficiency of modern buildings.

Integrating solutions such as the cool roof or green roof requires careful attention to technical details and local environmental requirements. This can greatly increase a building's energy efficiency while remaining environmentally friendly. These solutions are also part of a wider strategy to combat climate change, as demonstrated by the impact of the white roof on global warming.

Preparing the roof for roofing

Before installing roofing, it's essential to prepare the roof surface. The roof must be clean and free of debris or vegetation. This ensures perfect adhesion of the product.

Moisture assessment is crucial. A damp roof can cause adhesion problems and impair waterproofing. Make sure the surface is completely dry.

The installation of a vapour barrier is often necessary. This component protects the roof from internal moisture build-up. It is placed under the roofing and plays a key role in the durability of the structure.

Preparing the substrate also involves repairing any cracks or imperfections. A smooth, even surface is essential for correct installation.

The roof must be inspected for structural soundness. Ensuring its robustness avoids future complications.

Installation and laying

Installing a roofing system requires precise, methodical work. Correct installation of the elements and careful bonding of the strips are crucial to ensure watertightness and durability.

Installation techniques

Roofing installation requires the expertise of a professional roofer. They start by preparing the surface, making sure it's clean and dry. This step is essential to ensure perfect adhesion.

Next, the roofing sheets are aligned and cut to the dimensions of the roof. This must be done with precision, to avoid costly adjustments later.

Installation always starts at the bottom of the roof, ensuring that the materials overlap. This ensures better water drainage. Joints must be perfectly aligned to prevent infiltration.

Gluing and applying the strips

Gluing roofing strips is a delicate operation. The roofer uses a special adhesive, applied evenly to avoid air bubbles. The strip is then pressed firmly into place to ensure a solid bond with the underside.

For application, the strips must overlap by at least 5 centimetres. This reinforces the seal, preventing water from seeping between the layers.

It's crucial to check that each strip is properly bonded and tensioned. This is to prolong the life of the roof. In case of doubt, a professional should be called in to rectify any errors.

Maintenance and repair

Maintaining a roofing system requires regular attention to avoid problems linked to water infiltration and to guarantee watertightness. Maintenance and repair techniques vary according to need, from regular inspection to more extensive interventions such as renovation.

Regular maintenance and inspection

Regular maintenance is essential to prolong the life of a roofing system. This includes clearing debris such as leaves and moss that can clog gutters.

Periodic visual inspection helps spot problems such as cracks or bubbles. Checking joints and sealants to make sure they're intact and securely fastened helps keep the roof watertight.

A professional can be engaged to assess the overall condition and provide appropriate recommendations.

Infiltration management and localized repairs

Water infiltration is one of the most common problems. Identifying a leak quickly is crucial to avoid considerable damage.
