Dryseal Flat Roofing

The Dryseal flat roofing system is a component based pre-cured GRP system, meaning it is much more versatile than ‘wet lay’ systems. Manufactured from long-established glass reinforced polyester (GRP), Dryseal can be installed over the existing roof covering as long as the deck is in good condition, easily accommodating the introduction of insulation to form a warm roof.

To ensure that your Dryseal roofing system is fitted correctly and offers the watertight protection it is designed to do, Dryseal must be installed by one of our Approved Contractors.

The Dryseal flat roofing system is guaranteed to remain leak free for 20 years and comes with an insurance backed warranty. The Materials Guarantee is supplemented by our Approved Installer’s Guarantee directly to the customer. Dryseal is manufactured under factory conditions in accordance with ISO 9001:2008 Quality and ISO 14001:2004 Environmental standards.

Dryseal commercial:

As a premium-quality, glass-reinforced polyester (GRP) roofing system, Dryseal is suited perfectly to commercial projects such as new-build property construction and private sector refurbishment jobs.

Dryseal heritage:

Designed for flat and low-pitched roofs, Dryseal is manufactured from high-grade polyester resins and glass reinforcement (AKA fibreglass or GRP). It is produced in the UK and serves as an ideal alternative to lead, as it doesn’t attract thieves and is far more cost-efficient.

Dryseal housing:

Combining aesthetics and performance, Dryseal Housing provides a hard-wearing, long-life solution for the homeowner or housebuilder looking for a flat roofing or low pitched roofing system, or an alternative to lead detailing.

BS 8612. Designed to Address the Sub-Standard Dry Fix Roofing Products

April 2018

Dry fix roofing to replace the use of mortar on slate and tile roofs has gradually developed over many years and grown in popularity. It is simple, fast, cost-effective and removes many of the issues related to the use of mortar, the reliability and weather dependency.

Revisions to BS 5534 in 2014 addressed the problems of failing mortar and required that all ridge and hip tiles be mechanically fixed, even when mortar was used, and this further increased the use of mortar-free roofing installations, but with this increase in demand for products, the industry also saw an increase in the numbers of products on the market with a wide range of different qualities.

The new Standard is the first-ever British product standard for pitched roofing dry fixed products and is intended to address the problem created by the appearance of poor quality products on the market by ensuring that all dry fixed ridge, hip and verge systems meet minimum agreed standards.

It establishes the suitability of dry verge products to be used as a fixing for perimeter tiles to resist wind uplift together with tests to determine the mechanical resistance to wind loading and therefore their suitability for any design wind exposure of the site and building.

The Standard also includes a test to confirm the ability of verge systems to shed water from the roof verge without staining the gable wall, sets out requirements for the specification of materials used to manufacture dry fix ridge, hip and verge products and their durability in UV exposure and artificial aging tests.

Other tests include the suitability and adhesion quality of ridge and hip-roll products to fit the wide range of roof tile profiles used in the UK, whilst requiring that they also meet the requirements of BS 5250:2011 for ventilation performance.

As a brand-new Standard, testing for performance and compliance under BS 8612:2018 is voluntary. Accordingly, independent test houses cannot yet offer all the testing covered by this new Standard, and most of the dimensional criteria stipulated in the Standard will be declared by the manufacturer.

Many of the elements contained within this new Standard are methods of assessment of level of performance rather than pass/fail criteria. Manufacturers claiming that their products comply with the Standard, or requirements of the Standard should be quite specific about what and how they are they are claiming compliance.

We expect to see that NHBC will start to require testing and confirmation of wind load performance and the avoidance of water run-off staining from verge systems under the Standard at the next issue Of the NHBC Standards, the 2018 Standards having only just come into force.

Hambleside Danelaw are familiar with the content of the new Standard and have been able to undertake indicative tests on the relevant products from the Danelaw range. It is expected that all the Danelaw brand dry fix products will perform very well under the various assessment criteria contained within the Standard.

It is possible that the industry will see some modifications to various manufacturers products over the next year or so, however as a manufacturer of high quality and reliable products, we do not expect that any of our product range will require any changes.
