Main Roofing Systems:

Adhered Roofs:

An adhered system will typically consist of a structural deck, adhered vapour control layer, adhered or mechanically fastened thermal insulation and adhered Sarnafil membrane.

Mechanically Fastened:

Mechanically fastened systems are suitable for both new and refurbishment projects of any size, providing cost efficient roofing systems for exposed applications.

Green Roofs:

Green roof systems are specified for a variety of reasons, principally to manage incident rainfall or to replace the biodiverse footprint that construction destroys; creating habitat for flora and fauna. But green roofs provide a wide variety of additional benefits including amenity, thermal mass, pollution reduction, natural cooling and aesthetics.

Ballasted Roofs:

A ballasted roof is one where the roofing membrane is restrained by means of either gravel or paving slabs. Green roofs are also classed as ballasted roofs but are covered in a specific section within this site.

Sika SolaRoof Is a 20 year guaranteed Solar Roof System based on an engineered non penetrative and lightweight mounting system the Sika SolarMount-1. Sika SolarMount-1 is an aerodynamic, lightweight mounting system for the installation of rigid Photovoltaic (PV) panels to flat roofs.

Self adhered membranes Sarnafil G 410 ELF SA is a self adhered hot air weldable roof membrane that combines all the traditional and proven advantages of a Sarnafil membrane with fast and easy installation thanks to a strong self adhered fixing attachment method. Cutting installation times by up to 50 per cent with no need for the use of adhesives on site Sarnafil Self Adhered is the quick, simple solution for installers, specifiers and building owners.

SIKA SARNAFIL EXPLOSIVE SUCCESS FOR ROYAL GUNPOWDER MILLS HERITAGE ROOF REFURBISHMENT

November 2019

A historic and archaeological treasure, the Royal Gunpowder Mills heritage site in Waltham Abbey, Essex, has been given a new lease of life with a stunning and sympathetic roof refurbishment.
Consisting of listed buildings, ancient monuments and natural aspect features, the site is a well-loved attraction. A busy hub of activity, it attracts thousands of visitors every year, with exhibitions and a programme of hands-on activities for school groups.

With previous roof coverings across the site's buildings close to derelict, a new roofing system was needed that would both guarantee a durable solution and fit with the aesthetic of the heritage buildings. To meet those needs, Sika Sarnafil G410-15EL FSA Lead Grey was specified alongside Sarnavap 1000E air and vapour control layer.

The high-quality roofing system was chosen after the project's main contractors Courtenay Builders Limited were impressed with the results from similar Sika Sarnafil projects. They also entrusted Contour Roofing with the specification and installation after seeing its award-winning track record with Sika Sarnafil.

As a site once home to tonnes of explosives and with visitors in throughout the refurbishment, the project proved challenging, requiring extensive attention to health and safety. A strict ban on naked flames and hot works meant that the plywood boards had to be primed immediately after installation and before exposure to any wet weather. The specification therefore considered this and the original system, which would have needed a completely dry substrate, was switched to a loose laid polyethylene air and vapour control layer that was more equipped for a faster installation in the expected conditions.

Further challenges were met due to the 45-degree pitch of the roof. Roof ladders had to be used to allow workers access to the complex angles and achieve a seamless finish, using Sarnafil membrane and bespoke Sarnametal flashings at abutments, changes of angle and ridge angles.

Although time consuming work that required the utmost skill to ensure the roofs were completed to the highest standards, the project was kept on track. With Contour's contract manager making daily site visits, coupled with regular site visits from Sika Sarnafil Technicians, the project finished a week early.

Jonathan Woods, managing director at Contour Roofing, says: "This was a particularly interesting roof refurbishment with unique and complex challenges due to the nature of the site. However, by ensuring we had the right team in place with relevant experience, and the added support from Sika, we were able to complete the installation a week early while still providing an excellent finish that wowed the client."

Securing a 20-year Sarnafil guarantee, the newly refurbished roofs have not only met the client's need for a stunning aesthetic, but have also provided a durable weatherproof roofing system – upholding the heritage charity's mission to conserve the site for the benefit of the general public.

SIKA SARNAFIL HD PROVES IT’S TOUGH ENOUGH

July 2019

New Elgin primary school in Moray, Scotland, has had a Sarnafil HD system installed to meet their need for a new high-quality flat roof refurbishment.
With previous roof re-coverings not up to scratch, the school needed a system to improve the building’s thermal performance, save energy and improve robustness – providing a solution tough enough to mitigate damage caused by vandalism attacks experienced at the school.

By combining the thickest single ply membrane available – 2mm – and the most robust insulation board – SarnaTherm HD – the Sarnafil HD system offered a resilient and well-insulated solution. Plus, with the 2mm membrane outperforming all other membranes according to puncture test data, the system guarantees a long-lasting roof.
Moray Council specified Sarnafil HD for the 2500m2 roof after having previously used Sika Sarnafil products for numerous other school and council properties with great success.

The main challenge of the refurbishment was installing the roof during term time in an operational school. However, all required health and safety measures were executed by principal contractor, Morrison Construction, ensuring the safety of those working onsite as well as staff, pupils and visitors.

Roofing sub-contractor A & B Buchan Ltd, a Sika Sarnafil Registered Contractor, was tasked with the installation. Despite the thicker HD membrane specified, their thirty years of experience with Sarnafil products meant the system was installed seamlessly by their expertly trained team.

Senior Technical Advisor at Sika, John Love said: “Despite the challenges of the project, regular site visits carried out by Sika and the excellent communication maintained between Morrison Construction and A & B Buchan Ltd meant the installation ran smoothly and was completed to the client’s satisfaction. This project is also a prime example of the many benefits of Sarnafil HD and we are thrilled with the final result in terms of durability and longevity.”

Moray Council said: “The design had measures of complexity, however, our Environmental Services Property section worked with Sika throughout the process to combat any issues and were completely satisfied that the end result is an efficient, effective and long-term flat roof construction.”

With a combination of the hard-wearing Sarnafil HD and the use of SarnaLite roof lights and SikaLastic liquid polyurethane to finish the installation, the durable roof is now protected for years to come. And with a twenty-year Sarnafil Plus Extended Product and Installation Guarantee, the school has gained complete peace of mind.
