Install flashing and flashing bricks on a tile roof

Flashing is the essential element that makes it possible to ensure the watertightness of a roof at the places of connection with a wall or with a stump of chimney and a good evacuation of the waters. From the classic mortar flashing (still widely used) or bitumen and aluminum grid sheet, to the shape accessories specifically studied today, depending on the roofing materials and the covering conditions, the range of solutions has highly enriched, allowing to give a specific and optimal answer to the different problems posed. This progress ensures that roofs have a better seal, regardless of the case presented.

To guarantee the tightness

The watertightness between the roof (here, in terracotta tiles, but also in slates or cladding) and a wall (for example at a gutter) or a chimney stump (or even at the ridge or a junction with a flat roof) can be provided by a simple mortar joint forming a flashing strip. This arrangement does not guarantee a perfect sealing of rainwater in the long term, hence the development of profiles in the form of angles, called "flashing" galvanized steel coated or zinc and with a flap of lead. They conform to traditional metal roofing accessories.
A brand like Terreal has developed a range of accessories in colors in harmony with the color of the facades and the tone of the tiles for a better integration of the flashings in the construction. A deployed metal flashing is used on new constructions whose facade coating has not yet been done (the expanded metal ensuring a better adhesion of the coating) and a folded flashing door in renovation, on a house whose facade coating is already done. This work can be done by a zinc roofer.

Ease of implementation

The implementation of this type of accessory is possible regardless of the weather and the season. It is easy and quick to grind, while ensuring a complete seal. Presented in length of 2 m, it is easy to transport and maneuver.

Flashing and flashing

Flashing Flashing

Flashing flashing for excellent adhesion of the coating.

The flashing flashing allows a good adhesion of the coating as well as a perfect finish.
Characteristics and techniques of installation : by covering and screwing.

Folding flashing door

The folded flashing door (or hem) is ideal on a façade that has already been plastered.

The folded flashing door is used on an already plastered façade. The fold facilitates the realization of a putty seal cartridge (with an extruder gun) for a perfect seal.
Characteristics and techniques of installation: by overlapping and screwing plus seal sealant.

Fronton flashing

Pedestal flashing (for a perfect lateral seal).

Lateral waterproofing of the wall and roof by overlapping with a flashing or bent flashing door.
Characteristics and techniques of installation: provide a flashing or bending flashing.

Reversible standard flashing

Reversible standard flashing for a lateral wall and roof waterproofing per lane.

A standard reversible flashing ensures a lateral waterproofing of the wall and roof per lane.
Characteristics and techniques of installation: Provide a flashing gate for grilling or bending.

Flashing hallway

Flashing hallway

Hall flashing (use a flashing or folding flashing).

Lateral sealing of the wall and the roof by corridor. The frontal flashing is to be cut on site according to the model of tiles.
Characteristics and techniques of installation : provide a flashing or bending flashing.
