Roof Flashings
What are Roof Flashings?
A vital part of any roofing project in sealing the roof against the wind and rain, roof flashings are used to protect any potential weak points of flat and sloped roofs from becoming damaged, which can make your roof vulnerable to flooding. Generally, we apply roof flashings along any edges, walls, valleys, or protrusions, such as chimneys, to offer the best protection.
What materials do we use for flashing?
Roof flashings can be made from a variety of materials including aluminium, copper, steel, rubber, or roofing felt. All our roof flashing sections are 3 metres long and are manufactured to suit individual orders in a wide variety of sizes, colours, and angles. They can be ordered in the same colour as the sheets or in an alternative colour to the sheets to provide a highlight or feature on the building.
Copper is the most popular metal flashing material choice due to its durability and ability to adapt to changes in weather. Though plastic is a less expensive alternative to metal, it can be worn down over time if exposed to direct sunlight.
What are Roof Flashings with lock roll edges?
At Rollaclad, we also offer Roof Flashings with lock roll edges, which are recommended for added rigidity, especially where straight building lines are important. This treatment eliminates sharp edges, which makes the roof flashings easier to handle on site. Additionally, we can also supply you with butt straps if required.
Why are Roof Flashings important?
To ensure a long-lasting and watertight structure, roof flashings are an important roofing component that needs to be correctly installed. Roof flashings create an impervious membrane around weak points all around the roof which helps you to fight against water infiltration, as well as damage caused to the joints around vents, chimneys, and skylights by extreme weather. For flat roofs, roof flashings are especially effective at preventing water from pooling and causing damage such as damp which incurs significant additional costs. Therefore, roof flashings represent a great costeffective way of keeping your costs down and giving your building the protection, it needs.
Which areas of the roof require flashing?
During initial roof installation, it is essential that any Flashing is installed properly as poor installation of flashing can result in premature roof deterioration. We understand that replacing or repairing damaged flashing can be annoying. Therefore, it is critical that you choose the right material from the beginning so that the flashing is durable enough and of a high enough quality for your needs, ensuring that the flashings are compatible with your other roofing materials.
For Chimneys, strips of flashing are placed around the chimney, sealing the intersection of the chimney and the roof. For Vents, the two common types of roof vents are hoods and pipes (AKA stacks).
For Skylights, a continuous piece of flashing is often used to create the seal needed to keep water out around
skylights. A dormer is simply a structural element that projects from the side of a sloping
roof.
Flashing can be installed as multiple square pieces that are added in between every row of
shingles (or whatever type of roofing material is used) surrounding the dormer or as a strip that is
placed around the projection and underneath the roofing material around it.

Eaves Roof Flashings
What are Eaves Flashings and where are they used?
To achieve a decorative finish across the wall, Eaves flashings are attached underneath the roofing
sheets at the eaves (gutter) end of the run. This helps to protect the facade from a wide range of
ever-changing weather conditions, providing support for the shingles, and creating a roof drip edge
that helps channel water into a gutter or away from the facade.
Why are Eaves Flashings important?
A key concern that is common to all eaves is withstanding wind forces as this is a very vulnerable
part of the building exterior. By withstanding suction forces and other adverse weather conditions,
the eaves of the roof help to keep the entire roofing from being peeled off during high wind
conditions. Therefore, Eaves Flashings are an essential low-cost investment to keep your roof
looking great whilst protecting you from the elements for years and years to come.
What Eaves Flashings are available?
At Rollaclad, we provide a range of eaves flashings in all standard colours and finishes. All our
flashing sections are 3 metres long and are manufactured to suit your requirements in a wide variety
of sizes, colours and angles. To prevent any accidents when fitting the steel and to stiffen the edges
up, all the flashings are safe edged (welted) to. If you want to provide a highlight or feature on the
building, they can be ordered in the same colour as the sheets or in an alternative colour to the
sheets. If you have any bespoke requirements (e.g., dimensions, colour etc.), then please do not
hesitate to contact us as we will always strive to meet them as closely as possible, providing you with
the best-suited eaves flashings for your needs.
How can Eaves Flashings with lock roll edges help?
Do you desire greater rigidity for your roof or are straight building lines particularly important? If so,
we would particularly recommend eaves flashings with lock roll edges. To make the flashings easier
to handle on site, the lock roll edges eliminate sharp edges, which also makes installation much
easier and quicker. If required, we can also supply you with Butt straps, which are a strap or plate
covering a butt joint and secured to both pieces.
Can we help you with anything else?
As well as eaves flashings, we can also supply a wide range of other flashings depending on your
needs, including ridge caps, apron flashings, barge flashings, drip flashings, and parapet flashings.

Drip Roof Flashings
What are Drip Flashings and where are they used?
Installed at the edges of the roof, Drip Roof Flashing is metal flashing that keeps water away from your fascia and from getting underneath your roofing components. The drip flashing overhangs the sides of the roof and has a small metal flange which is slightly bent away from the fascia.
Additionally, the drip flashing is non-corrosive and non-staining. This protects your roof’s and your building’s aesthetic appeal whilst maintaining strong structural stability. Without drip roof flashing, water can get behind your gutters and cause rot in both your fascia board and roof decking.
Therefore, Drip Roof Flashing is a high-value investment which will protect your building for years and years to come.
Why should I use Drip Flashing?
Drip flashing directs water away from the fascia, which prevents water from rotting the fascia over time. Additionally, drip flashing protects the decking edge from water penetration during periods of significant rainfall, which are becoming increasingly common due to climate change. As well as this, drip flashing seals any gaps at the bottom of the roof where there is commonly a gap between the decking and the fascia which could allow small animals to enter the attic. During the colder winter months, water can freeze along the roof and in the gutter, creating ice dams that can block the normal flow of water running along the gutter. To protect the bottom of the roof line, especially
during the colder winter months, drip flashings are essential. As well as preventing movement between fascia and deck boards, drip flashing assists gutters to direct water away from your house and foundation, prolonging your roof’s longevity and improving its overall effectiveness.
What Drip Flashings are available?
At Rollaclad, we provide a range of drip flashings in all standard colours and finishes. All our flashing sections are 3 metres long and are manufactured to suit individual orders in a wide variety of sizes, colours and angles. To provide a highlight or feature on the Building, they can be ordered in the same colour as the sheets or in an alternative colour to the sheets. If you have any bespoke requirements (e.g. dimensions, colour etc.), then please do not hesitate to contact us as we will always strive to meet them as closely as possible.
How can Drip Flashings with lock roll edges help?
As well as standard drip roof flashings, we can also supply drip roof flashings with lock roll edges.
These enhance rigidity and are especially useful where straight building lines are important. The lock roll edges also eliminate sharp edges, which makes the flashings easier to handle and install on site.
If necessary, we can also supply you with Butt straps, which are a strap or plate covering a butt joint
and are secured to both pieces.
Can we help you with anything else?
As well as drip roof flashings, we can also supply a wide range of other flashings depending on your needs, including ridge caps, apron flashings, eaves, barge flashings, and parapet flashings. For more information about any of our Roof Flashings or any of our other products, please do not hesitate to contact us by email (sales@rollaclad.com) or by giving us a call (+44 (0)1792 893985).
Ridge Roof Flashings
What are Ridge Flashings?
Flashings and trims are a great way to finish off your roofing project, they deliver a quality finish on the corners and ridges of your roof, ensuring that you have a watertight roof allowing any rain water to run down the facia. Generally, an externally finished ridge flashing is used at the Apex of a roof to bridge the gap and a form a cover between the two roof slopes, enhancing the robustness of your roof and providing a better finish. At Rollaclad, we can provide you with stock ridges to suit our stock roofing sheets, which are generally folded to 130 degrees with a standard a 3 metre in length.
However, you can also order other bespoke ridge flashings on demand with larger or smaller wing dimensions, or in different colours. This ensures that you have the perfect ridge flashings for your needs.
Why are Ridge Flashings important?
Similar to barge flashings, ridge flashings are essential to maintain a strong roof structure by preventing wind from getting under the roof sheets and causing the roof sheets to lift up.
Additionally, ridge flashings protect the roof from water intrusion from the apex joint. Typically, ridge flashings are made with a 10-degree angle in standard 3 metre lengths, but they can also be customised for your individual needs. Regarding roof sheet flashings and ridge flashing, it is very important that you use the best quality to avoid any problems with your sheet roofing in the future, such as leaks and moved sheets. At Rollaclad, we have been manufacturing and supplying the best roof sheets and related parts for many years, allowing us to use our years of experience to provide the best service to our customers.
How is installation carried out?
Ridge flashing installation is a task that should be carried out towards the end of your roofing project. If you have a sloped roof with two sides, which meet at an apex in the middle, it is essential that you know how to install roof cap ridges. This is because roofs without adequate ridge capping could be a costly error that you may end up paying significant costs for in years to come. Largely, this is caused by rain, snow and winds seeping through the gaps in the apex of the roof, compromising your energy supply and allowing heat to escape.
First, we determine which end of your ridge is least affected by the wind. Your first ridge flashing will be laid at this point, and each flashing thereafter overlapped by the next flashing on the run by an absolute minimum of 150mm. If required, we can use foam fillers for eaves and ridges to seal off ends or this can be left out if you wish to keep the ventilation. Fillers can help ensure a robust weather resistant joint as well as keeping out birds and vermin.

Barge Roof Flashings
What are Barge Roof Flashings?
To complete any roofing project, every roof requires flashings and trims as flashings play an integral role in sealing the roof against the wind and rain. This is because flashings help to protect your roof from changeable weather conditions which are becoming increasingly common in the UK and around the world thanks to climate change. To trim and seal off the edge of a roof, you can use Barge board flashings at the end of a run of sheets. By using barge boards at the gable ends of Apex roofs, you can help to deflect wind, which can protect the roofing sheets from lifting up
unnecessarily. If these fall off and/or are damaged, then this can result in significant replacement or
repair costs later on. Therefore, barge roof flashings represent a cost-effective investment that will protect your roof for years to come.
Where are Barge Roof Flashings used?
Generally, barge board flashings can be used at the gable ends of an apex roof, to flash around a single sloping pitched roof and on the corners of buildings. Barge roof flashings provide protection against high winds, and closure between sheets and walls, ensuring that your building has a professional, clean, and tidy finish that is robust and looks fantastic.
What Barge Roof Flashings are available?
At Rollaclad, we provide a range of barge roof flashings in all standard colours and finishes. All our flashing sections are 3 metres long and are manufactured to suit individual orders in a wide variety of sizes, colours and angles. They can be ordered in the same colour as the sheets or in an alternative colour to the sheets to provide a highlight or feature on the Building.
If you have any bespoke requirements (e.g. dimensions, colour etc.), then please do not hesitate to contact us with your bespoke requirements as we will always strive to meet them as closely as possible. This ensures that we can provide you with the best-suited barge roof flashings for your needs.
How can Barge Flashings with lock roll edges help?
We can also supply barge roof flashings with lock roll edges which we recommend for added rigidity, especially where straight building lines are important. The lock roll edges help to eliminate sharp edges, which in turn makes the flashings easier to handle on site. Consequently, installation is much simpler, easier, and less expensive, saving time, money, and effort. Additionally, we can also supply you with Butt straps if required, which are a strap or plate covering a butt joint and secured to both pieces.
As well as barge roof flashings, we can also supply a wide range of other flashings depending on your needs, including ridge caps, apron flashings, eaves, drip flashings, and parapet flashings.

Corner Roof Flashings
What are Corner Roof Flashings and where are they used?
Essentially, Corner Roof Flashings are barge board flashings which are used vertically rather than horizontally. Corner Roof Flashing is used to protect any potential weak points of flat and sloped roofs from becoming damaged, which can make the roof vulnerable to flooding. When you need to cover the gap in the roof sheeting occurring at the corners of buildings, you will need corner roof flashings as in most sheds or homes, wall cladding generally stops and restarts at the corners. To finish the cladding run, corner flashings are used at the corners of buildings. Corner roof flashings
are used at the end of a run of sheets to trim and seal off the edge of the roof. In order to weatherproof the building as well as add to the building’s aesthetic value, any profiled clad roof needs flashings to retain their protection and value over time, delivering significant cost savings.
What Corner Roof Flashings are available?
At Rollaclad, we provide corner roof flashings in all standard colours and finishes using only the highest quality components for all our roof flashings. This means that you can be confident that your building will stay protected from the elements for years to come.
