Roof Flashings & Fabrications FAQs
What are flashings on a roof?
As far as flashings & fabrications go, roof flashings are an incredibly important part of the roof since they protect roof joints from water and weather damage.
Roof flashings are usually made from galvanised steel in industrial buildings and work by routing water away from other areas of the roof. They are always used where the roof plane meets a vertical surface to prevent water pooling and weather damage. You’ll often see roof flashings fitted around other features too such as skylights and chimneys.
There are several different types of fabricated flashings, including continuous (a long single piece of steel), base roof flashings (usually two pieces of flashing for roof features), counter-flashing and step flashing (roof to wall fabricated flashings).
What are the different types of roof flashing?
There are several different types of roof flashings, and these are:
Continuous fabricated flashings. Often referred to as apron roof flashings given their large apron like appearance, continuous roof flashings are long single pieces of fabricated flashings that carry water away. They typically have built-in expansion joints so they can expand and contract far more easily.
Base roof flashings. Some roof features, such as skylights, have two or more flashings & fabrications. This is to make sure that running water always meets a flashing surface that directs it away from the roof. When the roof materials naturally expand and contract, the base roof flashings flex, so the entire system remains secure.
Counter-flashing. Placed opposite or above base roof flashings, counter-flashing is secured on or into a wall, curb, pipe, rooftop unit, or other surface to cover and protect base roof flashings.
Step roof flashings are fabricated flashings that have a 90-degree bend in the centre. They are used for roof to wall flashing, and usually multiple pieces are installed in layers to ensure the water flows away from the wall.
Parapet roof flashings are used to waterproof and cap the ends of vertical sheets or masonry walls.

What are the material options for industrial roof flashing?
Although most of the roof flashings we supply tend be made from galvanised steel or aluminium, flashings & fabrications can be made from a variety of materials.
Plastic and rubber are mainly used as caulk and are excellent water repellents. However, PVC cannot come into contact with asphalt, making it unsuitable for some builds.
Roofing felt is asphalt-saturated, meaning it is an option but must be used with roof flashings material otherwise it will not be fully waterproof.
Aluminium is an incredibly malleable fabricated flashing meaning it can be bent to shape with little force, which is great for unusual roofs.
Copper is more difficult to bend and form than aluminium but is more durable. It is only really used to custom match a copper roof.
Galvanised steel is robust and durable type of material used in roof flashings. It is also low maintenance and rust proof and is one of our biggest selling roof flashings.
What is the expected lifespan of roof flashings?
Most of the leading manufacturers of roof flashings offer a 25 year guarantee on their flashings & fabrications. The warranty is valid provided the roof flashings have been specified and installed correctly and have been maintained to the expected standard.
Therefore, it’s important that roof flashings are routinely expected to make sure that nothing has caused any unforeseen damage and that debris and other items are cleared away.
What are the options for aluminium roof flashings?
Aluminium roof flashings can be supplied in a wide variety of thicknesses depending on the application but tend to between 0.9mm and 3mm thick. They can be supplied as mill finished, pre coated or powder coated after fabrication. The sheet sizes are expansive and range from 3000mm in length to 1500mm wide.
Given the flexibility of the metal, aluminium roof flashings can be bent to almost any size or shape, including to bullnose and parapet fabricated flashings.
These roof flashings can be supplied as polyester powder coated flashings in a wide range of RAL colours, BS colours, heritage texture, metallic or anodised finish. Made specifically and uniquely to each project, our powder coating service allows us to be able to cover simple standard aluminium flashings, secret-fix cappings or cover a more complex projects with bespoke capping roof flashings profiles.
