Flat Roofs
All Northern Roofline roofers are Sarnafil registered installers. We have substituted the traditionally used felt roofing system to the new PVC waterproof system using Saranfil. All our flat roofs are immune to movement due to expansion of wooden structure when temperatures change. Sarnafil flat roofs are resistant to solar rays and harsh weather conditions that can damage other types of flat roofs.
Sarnafil is know a one of the world best PVC waterproof products because of its durability and this is the reason why we use it. The Sarnafil product was first introduced over forty year ago. One of the first instances where this was used was in 1964 for a Beil swimming pool in Switzerland. This swimming pool is still in use today, which shows how long-lasting the Sarnafil product is.
Sarnafil has been used throughout the UK for many commercial projects including Bluewater shopping centre, Bristol Airport and the British Standards Institute. We take the experience and knowledge gained from working on commercial projects and use these skills to provide a durable flat roof for all our domestic customers. All of our roofers are fully qualified an trained by Sarnafil. We can assure you that you will receive the best service and quality flat roof installation by a Sarnafil registered roofer. We provide our services to customers all over the North of England, including Manchester, Leeds and York.

Felt roofs can be prone to damage from UV rays and movement created by the building, in turn this can cause blisters, cracks and splits to occur. Damaged roofing can be a result of poor installation and bad design. To be able to install a Sarnafil roof, your roofer needs to be fully trained unlike other roofing solutions.

Many problems can go undetected, such as rot and moisture, which can start to accumulate beneath the felt and is most likely to go undetected until it reaches the inside of your home. If required, we can supply you with new insulation and decking boards which we will fit for you. All of our roofs provide long lasting solutions, when carried out by a Sarnafil registered installer.

Sarnafil edging is installed, once the fleece layer has been applied for separation. Then water stops get secured mechanically on to decking.

The next step is to apply the Sarnafil roofing membrane to the structure to safe guard against strong winds. We used a fixing and design process that is guaranteed and completed in accordance to BS6399:Part 2. The fixings that are installed are sealed permanently.

To ensure the strength of the roof is secured all joints, laps and other details are welded in place.

All details are reinforced using steel, with our seals being proven to handle movement from the building and creates a waterproof joint against the wall.

The Sarnafil flat roof has been completed.
We offer a range of roofing services in Manchester, Leeds and York, these include fascias and soffits to complete re-roofing services. For more information on all our services, please contact us via our enquiry form today.
