High expectations for roofing

Planning figures, in particular, a 35% increase in floor area approvals, demonstrate the growth potential in the roofing products sector.

Latest planning permission statistics from the CSO show that in the period January-September 2015, a total of 3,282,000m² of floor area planned was granted permission, representing an overall increase of 35% on the same period last year.

A total of 1,519,000m2 was approved for new dwellings with a one-off house having an average floor area of 243m² and a scheme house having an average floor area of 144m². Of the total floor area planned for new houses and apartments over the year so far, one-off houses accounted for 44%, multi-development houses 48%, and apartments 8% (see page 6 for full breakdown by county).

In regards to agricultural buildings, the first nine months of 2015 saw an increase of 35% on the same period in 2014. In total, 494,000m² of floor area was granted permission compared to 352,000m² over the same period the previous year, reflecting a substantial 40% increase. New constructions in the Buildings for Commercial and Industrial Use category have also experienced growth, up 40% in the floor area planned with 402,000m2 approved. The trend continues into Buildings for Health, Education and Social Use with a total of 422,000m2 planned, up on last year by 18%.

While planning permission rates are high, commencement notices and completion rates are slow as securing finance to build developments remains a major stumbling block. However the outlook remains positive and provides strong potential for growth in the supply of roofing products to the domestic market over the next 12 months (Many thanks to Claire Kelly of Tegral for supplying the statistics).

THE ROOFER’S “BEST KEPT SECRET”

The roofer’s best kept secret is finally out. According to Everbuild, it’s Aquaseal Liquid Roof,

Aquaseal Liquid Roof – the one component, all-weather roofing system.

the new, one-component, easy-to-use, all-weather roofing system, ideal for waterproofing flat and pitched roofs. The product, from Everbuild, a Sika company, creates a solid waterproof membrane, which covers the entire area without any seams. Liquid Roof is applied in two coats straight from the tin and has a moisture-triggered curing system to allow fast curing. Liquid Roof is completely rain resistant after just 10 minutes and will even cure if a pool of water forms on top of it, according to Everbuild. Suitable for use on a variety of substrates including concrete, mortar, brick and stone, Liquid Roof can be used on new roofs as well as refurbishing old.

Available in slate grey colour in 7kg and 21kg tins, Liquid Roof will leave you with a professional-looking, fully waterproof roof in just five easy steps.

TORCH-APPLIED ROOFING

IKO has an extensive range of torch-applied roofing systems.

IKO describes its range of torch-applied roofing systems as being one of the most recognised, established and trusted product lines across Ireland and Europe. An IKO spokesperson commented: “It is because of our unparalleled choice of flat roof waterproofing systems that IKO is the preferred partner for so many building merchants, specifiers, contractors, and local authorities throughout the country. Regardless of your budget, IKO has a product to suit your project, torch-on or cold applied. Whether it’s new build or a refurbishment project, installation by a skilled contractor or by a DIY enthusiast, there is a solution to meet every need and budget.” IKO offers a diverse range of bituminous flat roofing membranes, as well as manufacturing and distributing an extensive range of Hyload structural waterproofing products, IKO Rubershield pitched roofing membranes, IKOflash lead-replacement flashings, IKOpro innovative liquid applied systems and the world-renowned range of bitumen roofing shingles. The spokesperson added: “It is this product diversity which enables us to be the first point of contact for our merchant partners with any roofing or waterproofing project, whether it is a private dwelling or commercial development, one roof or many.”

AIRTIGHT AND WINDTIGHT

MacCann & Byrne imports and distributes the complete range of pro clima high performance intelligent airtightness and windtightness membranes tapes and seals. It is now widely accepted that wind penetration of roofs can lead to a significant reduction in thermal performance. In recognition of this, MacCann & Byrne have launched pro clima Solitex Plus Connect. Solitext Plus Connect is a windtight, yet diffusion-open, vapour permeable membrane, suitable for pitched roofs.

Solitex Plus Connect features a pre-applied tape guaranteeing optimal windtightness for pitched roofs. Niall Crosson, Senior Engineer at MacCann & Byrne outlines the key features of Solitex Plus: “Unlike many conventional breather membranes, which use an air- permeable micro-porous technology, Solitex Plus Connect features a pre-applied tape, an integrated reinforcement netting and employs a closed cell, vapour permeable layer.”

Solitext Plus Connect is a windtight, yet diffusion-open, vapour permeable membrane, suitable for pitched roofs.

This provides a combination of key benefits, Niall notes, including:
• optimum windtightness and weathertightness with pre-applied tape;
• greater cost-effectiveness and increased speed of application with pre-applied tape;
• extreme resistance to wood preservatives, wood treatments or natural wood resins;
• extreme resistance to on-site chemicals;
• complete resistance to air penetration;
• extreme nail-tear resistance;
• extreme watertightness;
• exceptional thermal stability; and,
• high levels of protection against condensation due to high vapour permeability.

Niall sums up: “As the roofing membrane is the second line of defence for the roof, it is absolutely essential that it provides optimum resistance to wind-driven rain, which we are accustomed to in Ireland, as well as minimising condensation risk. With Solitex Plus Connect, this performance is guaranteed under extreme conditions typically found on construction sites where roofing membranes need to provide durable protection against intruding dampness, particularly in exposed areas during the building phase.”

With proven reliability and performance, Solitex Plus Connect not only optimises weathertightness but also maximises thermal performance. The German engineered and produced Solitex Plus Connect roofing membrane has full British Board of Agrément Approval.

LEADING THE WAY

2015 has been a busy year for Tegral, Ireland’s longest established manufacturer of roofing materials. Living up to its reputation as the market leader, the company has invested heavily in training and innovation this past year.

Paddy Kelly, MD, Tegral.

In March, the company officially launched the Tegral Academy. Established as a centre of excellence for roofing contractors, the Tegral Academy aims to raise the standards of roofing in Ireland today. Initial plans were to train 300 to 400 delegates in best practice standards of roofing and, due to a hugely positive industry response and an overwhelming demand, Tegral increased its number of training days in 2015. In fact, by the end of the year, it had trained almost 500 roofing contractors.

In June, Tegral launched Endurance, which it describes as Ireland’s strongest slate. Tegral says it is the highest density slate on the Irish market, offering the best resistance to Ireland’s famously volatile weather, with extra fibres that give the product its highest flexural strength and a specialist silicone paint providing a unique type of water repellence.

Then, in October, Tegral launched Vertigo, the first range of fibre cement slates specifically designed for use on vertical facades, as well as roofs, according to the company, opening up a host of creative possibilities for architects. Vertigo was specifically developed in response to the growing trend towards using fibre cement slates across the whole building envelope.

And to top off what has been a very rewarding year for Tegral, the company also managed to maintain its BES 6001 Sustainability Standard, once again achieving the “Very Good” rating. This demonstrates that Tegral products are made with materials that have been responsibly sourced from suppliers who have documented health, safety, quality and environment systems and underpins Tegral’s ongoing commitment to sustainability.

Paddy Kelly, MD, Tegral commented: “The year ahead marks an important milestone for Tegral, as it is our 80-year anniversary. Being in business for so long wouldn’t have been possible without a strong reputation for quality products, competitiveness and continuous innovation, all of which we are very proud of, and we will continue in this vein throughout 2016.”

I-JOIST INNOVATION

Steico, a leading European manufacturer of engineered timber joists, offers a bespoke, enhanced floor/roof joist designed especially for the smaller developer and renovator. The product, Steico Tradejoist, is available in Ireland through suppliers, Wood Concepts. It offers what Wood Concepts describes as a simpler engineered timber floor/roof solution for house-building, self-build, and home improvement or renovation projects.

The complete kit, combining tradejoist beams with either Weatherdek or new weatherprotect panels and fixing accessories, ensures a superior performance, according to Steico. Wood Concepts says this initiative is a positive move to simplify the I-joist experience for smaller users and developers, and to open up the supply chain to non-specialist merchant customers.

Steico tradejoist uses a simplified single specification TJ60/220mm deep I-joist format available ‘off the shelf’ in three cut lengths: 3.6m, 4.8m and 6.0m. All the accessory products are provided to complete the project. According to Steico, key features include: spans up to 5m for standard loads; solid timber flange for ease of fixing; colour-coated for enhanced moisture resistance; beams are clearly stamped with usage criteria; lightweight and easy to cut; and ease of access for all service runs and ducting.
