The panels are sized to the length of your roof rafter plus fascia.  Any trims and other fabrications such as eave flashings and soffits are supplied in 3 metre lengths.  

All panels are packed and delivered to site in a crate providing protection, and covered with polythene to minimise water ingress. 

The lead time quoted ranges from 2-8 weeks, depending on your individual colour requirement and our on-hand stock availability.  

However, it should be noted there is high demand on roofing installers and therefore early engagement is recommended circa 6 months to avoid delays in the commencement of your project. The chosen installer will be able to manage the lead time and order placement with Vertix Systems, generally by placing a reservation order.  Vertix Systems will purchase the material specified for your project to meet the required delivery time to site. 

When the roof is ready to be measured for the final order, it is typically 4 weeks from placement of order or payment to delivery to site. 

The key characteristic of a standing seam system is that the fixings are concealed, enhancing the aesthetics and reducing the risk of leaks from potential fixing points. The seam detail and closing mechanism of a standing seam vary from system to system. Some feature a convenient click-and-lock mechanism, whilst others require manual closure or the use of specialised machinery. Vertix EasySeam Roof System uses a snap and lock system which makes it quick and easy to install.

Longevity 

Metal standing seam roofs have an impressive lifespan and can last for over 50 years when properly installed and maintained.  

Eco-Friendly and Recyclable 

Metal standing seam roofs are environmentally friendly. At the end of their life cycle, they are fully recyclable, minimising the impact on landfills and reducing the demand for new raw materials. 

Standard Form of Construction 

Metal standing seam roofs are often classified as a standard form of construction. This designation has practical benefits, such as making it easier to secure standard house insurance and a mortgage on the property.  

Concealed Fixings 

A key design feature of metal standing seam roofs is the concealed or secret fixings. This not only enhances the overall aesthetics of the roof but also eliminates a potential source of leakage at fixing points. The result is a clean and streamlined appearance that minimises the risk of water infiltration. 

Energy Efficiency 

Vertix EasySeam Roof and Wall Cladding Systems are what is termed as fully supported, typically fitted directly to a solid substrate, such as plywood or a metal deck. They have a flat section with a relatively small 25mm high seam which is where the panels are joined. The panel is nailed to the OSB Board on one side and clips over onto the next panel on the other side, snapping and locking into place.

Pre-finished steel standing seam roofs when fitted correctly, have a low whole life cost and minimal replacement when compared to tiles and or slate. 

The efficient use of the pre-finished steel material and minimal onsite waste means it is a low carbon solution (typically between 10-15 Kg of carbon per sqm.) Steel is also 100% recyclable at the end of its life, meaning the standing seam offers a cradle to cradle solution. 

Vertix EasySeam Roof System is easy to install, allowing the building to become watertight in a shorter timescale compared to traditional standing seams and other building materials, delivering a speedy transition to second fix.

Vertix EasySeam Roof System has a fixing specification which, if used together with Vertix^® Systems tested and certified fixings, should ensure the roof remains intact in normal weather conditions during its service life.  

For more exposed regional conditions, Vertix EasySeam Roof System is available in a narrower (300mm width) profile which increases the fixings by 50% and in a Wide Rib profile which has a 50mm stiffening rib. Vertix Systems also recommend fixing panels to an 18mm OSB3 board where tests prove a significantly better pull-out strength when compared with 11mm OSB3 board. 

You can find out more information about wind loads and pull-out rates in the Vertix EasySeam Roof System Technical guide on our downloads page. 

Metal roofs sometimes have a reputation for being noisy during rainfall, but these tend to be single skin construction roofs. Vertix EasySeam Roof System is mounted on Oriented Strand Board (OSB) 3, with insulation to 0.15 U-value or higher and an air gap for the service void or ventilation gap. All of this ensures the noise of rain on the roof is minimised.  

Where this type of roof can be noisier is in high wind areas. In such situations, tile roofs can chatter and low pitch standing seam roofs can drum. To reduce drumming, Vertix Systems recommends the use of either Vertix EasySeam Flat Standing Seam profile in 300mm width or Vertix EasySeam Wide Rib Profile which has a 50mm central stiffening rib.

5 degrees. This is because a slight slope is required to ensure water run-off and prevent ponding which can compromise the durability of the roof over time.

It is important to mark the layout of the roof prior to installation. The end panels are reduced to adjust the position of the standing seam. You will need to make a starter and end panel to suit the roof. The verge trim with the backing plate connects with this to give a neat finish. If there are penetrations in the roof, these will also need to be factored in when finalising the layout. For example, when using rooflights,150mm of EasySeam profile will be required each side of the roof light. 

Detailed instructions for laying out and calculating start and end panels are included in the Vertix EasySeam Roof System Installation Guide on our downloads page.

Yes they can.

For a soil vent pipe or a wood burner flue, Vertix Systems recommends use of a Dektite. This is a type of roof flashing made from rubber or silicone and is designed to create a watertight seal around pipes or other penetrations on a roof. 

Where a Velux rooflight is used on a roof with a pitch above 20 degrees, Velux supply an EDQ flashing kit. Below 15 degrees the can be installed as a square penetration. 

For a roof light or square chimney, Vertix Systems can supply a square penetration flashing.   

Detailing for these are available in the Vertix EasySeam Roof System Technical Guide or Vertix EasySeam Roof System Drawing details pack on our downloads page. 

The terms “warm roof” and “cold roof” refer to different methods of insulating the space above the structural elements of a building, such as the rafters or joists. These methods have implications for energy efficiency, condensation, and the overall performance of the building.  

Warm roof 

In a warm roof construction, the insulation is placed above the structural deck, typically on top of the roof rafters. This means that the entire roof structure, including the rafters, is within the insulated envelope of the building. The warmth from the heated interior of the building helps to keep the roof structure above the dew point, reducing the risk of condensation. Warm roofs are generally considered more energy-efficient as they help to maintain a consistent temperature throughout the structure. 

Cold roof 

In a cold roof construction, insulation is placed either at the ceiling level (just above the ceiling) or between the rafters, allowing for a ventilated space between the insulation and the roof deck. This creates a “cold” or unheated attic space above the insulation. Cold roofs rely on ventilation to remove any moisture that may accumulate, preventing condensation within the roof structure. Cold roofs are simpler and may be more cost-effective to install but they are less energy efficient than warm roofs and therefore ongoing costs may be higher. 

The choice between warm and cold roof designs depends on factors such as climate, building design and budget. Warm roofs are often favoured in colder climates to prevent issues with condensation, while cold roofs may be more common in milder climates where the risk of condensation is lower and ventilation is easier to achieve.

Vertix^® Systems can supply metal gutters and downpipes to complement EasySeam^® Roof and Wall Cladding Systems. There are 3 different gutter options to choose from; external internal or hidden gutters. External gutters are standard metal gutters and are supplied with all the components including downpipes. They are available as a half round or rectangular shape. Internal and hidden gutters are made from pre-finished steel backed with a thick membrane and are supplied with the joint brackets and outlets. 

You can find more information about guttering and downpipes in the Vertix EasySeam^® Roof System Technical guide which is on our downloads page.

Vertix EasySeam^® Roof System can accommodate PV solutions. There are three main options to consider:- 

• Stick on laminate photovoltaic panels- these would have to be applied in the factory and are not a retro-fit option. 
• Standard crystalline photovoltaic panels 
• Crystalline photovoltaic panels integrated into the roof 

When considering photovoltaics, all structures will need to be checked by a competent structural engineer to ensure they can take the added weight of the photovoltaic panels. 

You can find more information about these different PV technologies in the Vertix EasySeam^® Roof System Technical guide which is on our downloads page. 

Exceptional Durability 

Metal standing seam roofs can withstand the harshest elements, including heavy wind, rain, intense sunlight, and snow. This resilience ensures a long-lasting roofing solution that can endure the test of time and various weather conditions. 

Low Maintenance 

Metal standing seam roofing is a “fix and forget” system, meaning once installed, it demands minimal ongoing maintenance. This not only saves time and effort but also reduces the long-term cost of roof care and upkeep. 

High-End Appearance and Finish 

The sleek and modern appearance of metal standing seam roofs sets them apart from traditional metal profile systems. Clean lines and smooth surfaces create a high-end finish that enhances the aesthetics of any structure.  

Metal standing seam roofs offer excellent energy efficiency. They naturally reflect heat back into the environment rather than allowing it to build up inside the building. This means that in the summer, the roof helps keep the interior cooler, while in the winter, it aids in maintaining warmth.
