RCC Roofing Dryseal Contractor on DIY SOS

RCC Roofing’s Mike Wheeler Contributes to DIY SOS Project

Written by Bethany Smith on 26th March 2018. Posted in Blog, Dryseal Flat Roofing.

Long established Dryseal Approved Contractor Mike Wheeler of RCC Roofing from Bodmin, Cornwall recently contributed time and materials to a project for DIY SOS.

Mike Wheeler of RCC Roofing said;

“The experience in helping this family in Yealmpton near Plymouth was really fulfilling. Two members of the family are suffering from Cerebral Palsy and another family member has cancer. They had no way of paying for the costs of refurbishing their house, so contacted DIY SOS. We helped with a major part of the roofing work. It was a very hard but enjoyable time on the project where every trade helped each other. I even laid some turf! A fantastic experience and to be able to help to improve a family’s life to the extent that it has is quite overwhelming.”

Still going strong after 150 years

As the National Federation of Roofing Contractors celebrate their prestigious 125^th anniversary, our Dryseal Approved Contractor, John Williams & Company (Contracting ) Ltd, are proud to have been announced as probably their longest serving member.

The National Federation of Roofing Contractors (NFRC), as it is known today, was founded in 1892 when a group of 40 slate merchants and slaters met with the intention of forming an association. Over the years, the NFRC has expanded to include all major sectors of roofing eventually taking its current name in 1943. Across seven regions in the UK, it currently has over 1000 Trade and 187 Associate members, representing over 70% of the roofing industry by value.

The NFRC have delved into the archives and believe they have found the longest serving member whose continuous history goes back further than their own. The NFRC have published this statement,

“John Williams & Company, became involved with the London Association of Slate Merchants and Master Slaters very early on, with the company attending a meeting at the Charing Cross Hotel in London on 2nd November 1893, as far as we know the earliest reference to an existing member company. The company was owned by the Greenwood family from the 1870s right up until 2004, when MD, John Greenwood, retired. With no family to take over the company it was sold to Branch Director, John Howland, who had worked for John Williams & Company since 1974. John now runs the company with his son, Shaun, and as heritage members, they cherish their long history and membership of NFRC.”

John Williams & Company are a Dryseal Approved Contractor for Hambleside Danelaw. Since 2012, they have demonstrated quality workmanship throughout their projects. Dryseal Manager Andy Fell said “John Howland and his team have an enviable reputation for traditional roofing work, specialising in the heritage market and we were really flattered when John chose Dryseal as their alternative system to built-up felt in 2012. They have become a valued representative for Dryseal in Kent and the South East”.

Please join us in congratulating all the staff at John Williams & Company for such a recognition.

Green Roof added to Dryseal GRP flat roof system - NSBRC

The stand that delivers

Written by Dominic on 23rd January 2017. Posted in Blog, Dryseal Flat Roofing, Video Posts.

Our GRP flat roofing system Dryseal is featured as a permanent display at the NSBRC. The National Self Build and Renovation Centre is open to the public all year around, featuring quarterly events which focus on such topics as innovative green building methods and products.

We are now into our second year of showcasing Dryseal at the NSBRC but why? What benefits does it have for the system, the Hambleside Danelaw name and product visibility?

Andy Fell, Dryseal Manager is extremely positive about the centre “We were initially looking at ways to support our contractors and felt that using individual locations would be too restrictive and costly. We came to look at the Centre and felt it was fantastic. I feel that the permanent display has been worthwhile for us to highlight our top-quality system. To date, we have had over 140 leads created via the bar code scanners and at shows can meet face to face, when information and advice are initially exchanged and then followed up; a great way to build strong relationships.”

The Dryseal GRP roofing system is continually growing as an established and recognised product within the self-build and housing sectors. Having this permanent presence gives us the opportunity to continuously market Dryseal to an extremely relevant customer base. The stand markets itself as the features and benefits of Dryseal are permanently on view with literature available when
one of our team are unavailable to talk to.

Find out more information on the NSBRC or if you plan to visit the centre soon, make sure you come and see Dryseal on Stand 106.

Build green with Dryseal

Over the weekend of 7th to 9th October, the Dryseal team took to the stand at the NSBRC’s impressive Big Green Home Show. With 250 exhibitors in 67,000 square feet of exhibition space, there was a steady flow of budding self-build enthusiasts looking to fulfil their eco home objectives.

Architects, developers and self-builders visited the stand to find out about the numerous system benefits of Dryseal from one of our experts. One interested future customer wants to use Dryseal as the waterproofing layer on his soon to be constructed farmhouse on Bodmin Moor, with the intention of putting a field over it and grazing his flock of sheep there!

If you missed the show, don’t worry

The Dryseal stand is permanent – you can visit stand 106 free of charge all year round for more information about Dryseal. Dryseal is a GRP roofing system made from preformed components fitted complete with a 20 year insurance backed guarantee, is certified by the BBA and accredited for ‘zero-falls’ applications. The system is ideal for self-builders who need a durable and aesthetically pleasing roofing solution. Furthermore, Dryseal has exceptional detailing capabilities, and can be used to deal with awkward curved edge details.

The exhibition stand also shows how Dryseal can be the ideal waterproof membrane for a green roof and, being non- pollutant, it is also ideal for use in a grey water harvesting system.

GRP Roofing Common Misconceptions Explained

Written by Dominic on 31st March 2016. Posted in Dryseal Flat Roofing, News.

Having long witnessed disputes and arguments regarding various aspects of GRP roofing, we would like to assist in clarifying common misconceptions about the way that GRP roofing performs.

Traditional ‘wet’ laid GRP roofs, where liquid resin is applied directly to a timber substrate before having the glass reinforcement incorporated in situ can provide extremely tough, reliable and durable roofs that will outlast any thermoplastic or elastomeric membrane.

In this method of application, resin is absorbed into the surface of the timber substrate or decking, usually an OSB3 or roofing grade WBP plywood. Where there is sometimes a noise problem experienced with these type of roofs, it is usually due to the expansion and contraction of the decking through the seasons due to the boards dimensionally reacting to thermal and moisture content changes.

It is generally recommended that 8’ x 4’ (2.40m x 1.20m) roof decking boards are fitted with a minimum of a 3mm gap around all of the edges, and 10mm at an abutment wall to allow for this movement. In ‘wet-lay’ GRP roofing practice, this movement at the board edges should be restrained or eliminated by the application of additional glass reinforcing layers over the board joint. This can generally be perfectly successful if undertaken by properly trained operatives and large roof areas avoided as this introduces a requirement for expansion joints within the system.

CGI — The Dryseal is a component based flat GRP roofing system

Unfortunately, some might argue, roofing resins and roof edge trims are available to anyone who wishes to purchase and install them, often with insufficient knowledge or training. Board joints can be intentionally laid tight to minimise the movement at the edges, and the reinforcement at these joints can often be inadequate.

As the boards expand and contract, stresses can be induced at the edges due to movement, and just like a PVC fascia or gutter, creaking and cracking or banging noises can be heard. The movement at the board edges can also lead to excessive loads being transferred to the fully bonded GRP layer resulting in cracks that pass all of the way through.

Unlike fully bonded GRP roofing systems, Dryseal was developed as a pre-cured single layer membrane that is supplied on a roll and typically fully mechanically fixed through side edge overlaps at 300mm centres. This allows the GRP membrane to be secured to the roof construction, but still be allowed to move independently of the layers below. This capability allows for the differential rates of expansion between the differing roof layers and an installation that can reasonably be expected to last longer than a thermoplastic or elastomeric single ply system, and without the need for the inclusion of expansion joints unless required to accommodate specific areas of building movement.

Dryseal has carried BBA certification since 1995 including ‘zero falls’ applications and is only available to trained and approved installers, with perhaps one of the best insurance backed guarantees in the construction sector.

Dryseal is generally one of the most universal systems available and can accommodate almost all applications except where the requirement for the waterproofing layer is to be ballasted only.

Why choose Dryseal over ‘wet-lay’ GRP roofing systems?

Written by Dominic on 14th January 2016. Posted in Dryseal Flat Roofing.

Fast becoming the specification choice of a growing number of Housing Associations, Dryseal is the unique component based fibreglass or glass reinforced polyester (GRP) roofing system. Unlike ‘wet lay’ systems, the Dryseal system is supplied pre-cured and ready to install. All Dryseal GRP trims and membrane are manufactured under strict BS EN ISO 9001 and 14001 quality and environmental controls and then supplied via our network of fully trained Approved Contractors for installation on site.

Dryseal should not be confused with ‘wet lay’ systems, which comprise fibreglass reinforcement saturated with liquid resin hand laid on site. Wet lay systems have greater potential for error as the process relies on fair weather from the outset. Liquid resin containing a catalyst is applied directly to a completely dry new roof deck. Fibreglass reinforcement is then manually laid into the resin. The fibreglass reinforcement is rolled to fully saturate the mat and expel any air pockets in the laminate in a critical process called “consolidation”.

Common problems with ‘wet lay’ GRP installations.

The need to renew the roof decking boards on most projects.
An extra layer of plywood or OSB is necessary above the insulation for ‘warm’ roofs.
Too much catalyst added to the resin mix, leading to the cure being too fast and potentially brittle laminate.
Residual moisture in the roof deck can result in the cure process failing.
Too little catalyst added to the resin mix, leading to delayed curing of the lamination and project delay.
Temperature drop late in the day, potentially leading to un-cured top coat.
Un-reinforced deck board joints leading to stress cracking due to differential expansion rates between the roof deck and waterproofing membrane.
Expansion joints are often recommended on roofs above 30 m².
Guarantees often only cover the materials, rather than the installation.

The benefits of working with Dryseal:

Re-roofing work using Dryseal can be carried out re-using the existing roof deck, if it is in good condition. This saves on labour, landfill costs and reduces the risk of water ingress during re-roofing.
‘Warm roof’ installations are straightforward using standard flat roofing boards.
Lamination of pre-cured flat sheet joints much quicker than full ‘wet’ application.
Residual moisture in the original roof build-up will naturally vent out as Dryseal “breathes”.
Flexibility of installation allows better certainty of successful projects.
Thermal movement is catered for within the Dryseal membrane and fixing method, dramatically reducing the need for expansion joints.
Complex details are easily handled, due to a wide range of pre-formed trim options.
Full BBA certification covering un-restricted use under current Building Regulations.
Full technical and design support.
BBA certification covers ‘zero-falls’ installation – for terraces and green roofs.
Acceptable to the NHBC as a roof covering system.
‘Secured by Design’ accreditation and recommendation as a replacement for lead or copper on Heritage projects.

Northamptonshire Churches buckle from lead theft

Written by Bethany Smith on 2nd November 2015. Posted in Dryseal Flat Roofing.

It has long been a problem for churches and local Parishes, and thieves have recently struck again in Northamptonshire. In August this year, St Mary’s Church in Great Brington, the Spencer’s family church, became the latest target of lead thieves. The grade one listed church was stripped of over 3,000 square feet of lead from the roof, seriously debilitating the Church.

Recent thefts have led to a conference this week being held to discuss what can be done. The Archdeacon of Northampton will lead the seminar discussing steps that can be taken to prevent lead theft, and will provide an update on the situation in Northamptonshire.

St John the Baptist Grade 1 listed Church in Bromsgrove

Dryseal is a GRP component based roofing system that can be formed to look just like lead. It holds Secured by Design certification, a Police initiative to design out theft and improve security for buildings and is recommended by SBD as a viable alternative to lead or copper.
The Dryseal system is the ideal for heritage buildings as it is lightweight and holds no value to thieves. Hambleside Danelaw has been delighted to be able to assist in preserving English history with the re-roofing of various Churches throughout the UK.

GRP Material

Written by Dominic on 7th October 2015. Posted in Dryseal Flat Roofing, News.

pexels-photo-71241-1 — Egyptians used glass fibre reinforcement in the fabric of clay jars

Following the lead of the Egyptians who used glass fibre reinforcement in the fabric of clay jars to stop them breaking during transit, GRP or “Glass Reinforced Polyester” was developed for a wide range of applications by the British military during WW2.

The initial aim was to use GRP for a number of applications such as minesweeping, because of its lack of magnetic footprint. The benefits of GRP were subsequently picked up for use outside of the military in the boat building, motor manufacturing and construction industries.

As the name suggests, the material is produced by combining thermosetting polyester resin and glass fibres under strictly controlled factory conditions. Glass fibres are applied into the resin with each layer of fibres facing in different directions, enabling the stiffness and strength of the finished material to be controlled.

Why is GRP ideal for roofing?

GRP is a strong, lightweight material which is naturally watertight, aesthetically pleasing and has great longevity. Its bulk strength and weight being better than many metals mean that it can be readily moulded into complex shapes and can be used for a wide variety of roof coverings.

As GRP benefits from being fire retardant, easy to handle and UV resistant, it is ideal for roofing installations. The flexible material is incredibly versatile and easy to repair, and providing it is offered by a responsible manufacturer, is fully recyclable at the end of its service life.

The cost of lead theft and vandalism

Written by Dominic on 22nd June 2015. Posted in Dryseal Flat Roofing.

It is well documented that metal theft on railways is rife; costing Network Rail up to £16 million a year, and causing severe disruptions for British rail users. Similarly, the stripping of copper and lead from church roofs has also hit headlines in recent years, and although reducing, this is still a real issue for communities.

Heritage buildings are the most targeted and the most affected by lead theft as it is far more of a struggle to find funding for community buildings and churches. Indeed, replacement roofing cost the Church of England £10million in 2012.

However, opportunistic thieves are now looking to construction sites for more materials. Often leaving themselves open to theft through poor security, building sites have a wealth of materials, and thieves have come to know this.

What can I do to prevent lead theft?

Alongside standard security, site managers are encouraged to make it harder for thieves by moving precious materials off floor level. Any physical security such as barbed wire or anti-vandal paint must have the appropriate signage and must be placed at 2.5 metres or above to avoid legal liability.

However the most simple way to avoid metal theft is to combat this at the root and use a different roofing material altogether.

Dryseal defeats vandals and thieves

Dryseal is accredited with the Secured By Design certificate, a police initiated campaign to highlight the deterrent of thieved through the physical properties of a material. Dryseal holds no value to thieves, and yet is able to replicate the lead rolls synonymous with heritage buildings.

Furthermore, Dryseal itself is incredibly hardy. The durable and fire resistant material has been put to the test.
