IKO’s Long Term Solution
Remember a flat roof which has been designed and installed in accordance with the relevant British Standards and an IKO long-term solution can be trouble-free, providing it is properly maintained and checked at routine and regular intervals, with a note made of any items requiring attention. Key detail areas to check include flashings, upstands, penetrations, edge trims and drainage channels. Maintaining these checks will extend the life expectancy of the roof.
IKO also consider the longevity and lifetime value of an existing, updated or new roof, partnering with a school to make sure any future upgrades or developments such as solar or photovoltaic (PV) possibilities, increased insulation benefits, accessibility or additional drainage can be achieved and conform to building regulations.
A roofing system which has been designed and installed in accordance with the IKO recommendations and relevant British Standards can be expected to provide trouble-free service provided it is properly maintained.
With any roofing system it is essential that proper and adequate maintenance is undertaken at routine intervals to ensure long term performance and life expectancy. This is an integral part of the terms and conditions of any guarantee.
IKO Technical Services recommend that any IKO roofing system is inspected and maintained in accordance with the guidelines given in BS8217 : 2005, Clauses 11.3 to 12.2 inclusive. The frequency of inspections will depend upon local conditions, but there should be at least one visit each year. The presence of trees or local atmospheric pollution would suggest more frequent inspections.
During the course of regular maintenance inspections the whole of the roof should be systematically checked and a note made of any items requiring attention. Other than the main roof area, key detail areas to check include flashings, upstands, penetrations, edge trims and drainage channels.
BRE has assigned generic Green Guide ratings to various types of insulation. These thermal insulation ratings are the same for the following building types:
Domestic, Health, Commercial, Retail, Industrial, Education.
Although a number of different types of thermal insulation may be used within IKO’s roofing systems, rigid urethane polyisocyanurate (PIR) is the major type which would tend to be specified within the vast majority of warm roof build-ups.
Rigid urethane insulation which is pentane blown, and which has a density of 32 kg/m³ has been given a generic Green Guide rating by the BRE of A. IKO’s brand for this type of insulation is Enertherm.
To complement this generic Green Guide rating, IKO Enertherm insulation boards are manufactured in accordance with ISO 14001. Click here to download the certificate.
In addition, IKO Enertherm boards are only ever pentane blown, and therefore have a zero ozone depletion potential. The blowing agent used also has a global warming potential of 0. Click here to download our confirmation letter.
The Green Guide is part of BREEAM (BRE Environmental Assessment Method) and is an accredited environmental rating scheme for buildings. It was first published in 1996 and today contains more than 1500 specifications used in various types of building.
The Green Guide’s aim is to provide specifiers with a simple ‘guide’ to the environmental impacts of various building materials. The data used to generate the ratings is based on known information on the latest manufacturing process, the way in which materials are used in buildings, and the relative environmental performance of building materials and components.
The Green Guide examines the relative environmental impacts of the construction materials commonly used in six different generic types building including Commercial buildings (such as offices), Education, Healthcare, Retail, Domestic and Industrial.
The environmental rankings are based on Life Cycle Assessments (LCA), using BRE’s Environmental Profiles Methodology 2008
Materials and components are arranged on an elemental basis so that designers and specifiers can compare and select from comparable systems or materials as they compile their specification. Roofing materials are one of the major elements covered and, within this area, the Green Guide provides an extensive (but not complete) overview of ratings for materials used within common roof constructions.
Overall system ratings are based on analysis of thirteen core environmental impacts each of these impacts is measured on an A+ to E ranking system, where A+ represents the best environmental performance / least environmental impact, and E the worst environmental performance / most environmental impact. BRE then uses this data to provide a summary environmental rating – The Green Guide rating.
By evaluating the performance of materials and building systems against the thirteen specific environmental impacts, it is possible for the specifier to select specifications on the basis of personal or organisational preferences or priorities, or take decisions based on the performance of a material against a particular environmental impact.

Building Regulations (2)
Building Regulations, Part B:2006 (Volumes 1 & 2) make provisions which limit the use, near a boundary, of roof coverings which will not give adequate protection against the spread of fire over them. (The term ‘Roof coverings’ refers to the external layers of the roof but not the roof construction as a whole). The provisions regarding roof coverings are principally concerned with the performance of roofs when exposed to fire from the outside.
The performance of roof coverings is designated by reference to the test methods specified in BS476-Part 3:2004, or in accordance with BS EN 13501-5:2005.
Under BS476, the external coverings of roofs are classified by two letters in the range A-D, with an AA rating being the best. The first letter indicates the time for a standard flame to penetrate to a certain depth in the roof covering, while the second letter is a measure of the spread of flame over a roof surface.
These two-letter ratings are used by the Building Regulations to define minimum separation distances for roofs from adjacent property boundaries, and roof coverings designated as AA, AB or AC are un-restricted in respect this regulation.
The table below (reproduced from Approved Document B) sets out building/boundary separation distances for various categories of fire performance.
IKO’s bituminous membrane systems are tested and certified by Exova Warringtonfire. As a result, the following membranes gained an AA Fire Rating in accordance with the Building Regulations. They are also approved by the LPCB:
- IKO Ultra Prevent
- IKO Mach One
- IKO Safestick
- IKO Superflex
- IKO Goldseal
- IKO ProTorch
For further information, please refer to Approved Document B (2006 Edition): Fire Safety (Volumes 1 &2).
Similar principles to the England & Wales Building Regulations are applied by the Scottish Technical Standards, in respect of roof coverings.
BS476 ratings are used to form ‘Low’, ‘Medium’ and ‘High’ vulnerability categories for the fire performance of roof coverings. These vulnerability categories are then used to designate separation distances between roofs and adjacent boundaries.
Please refer to Section 2.8.1 of the Scottish Technical Handbook for further clarification of these criteria.
The roofing works to be carried out will need to comply with the requirements of Building Regulations 2000, Part L (Revision October 2010) in England & Wales, or The Building (Scotland) Regulations 2004, Section 6 of the Building Standards Technical Handbook in Scotland.
The calculation of thermal transmittance, or U-Values, for a roof is controlled by the above mentioned regulations. There are different procedures according to whether the roofing work is for new-build or refurbishment. Where the refurbishment works is part of a change of use of the building, the works should comply with the latest Building Regulations and any revision thereof.
In all circumstances, it is recommended that advice be sought from your local Building Control Office, as to the compliance requirements for this particular project. The following links offer outline guidance in specific areas:
Linked guarantees cover the workmanship and material performance elements of a newly installed roof but unlike a single point guarantee, responsibility is split between the materials manufacturer and the installing contractor. Whilst only one guarantee certificate is issued to the client, the contractor will sign the document to cover any labour defects and the manufacturer signs for the material element. Whilst linked guarantees are widely used, there can be responsibility disputes with this guarantee format that can potentially leave the client with an unresolved problem.
The roofing materials will usually be covered by product liability insurance (as in the case of IKO PLC) however, the workmanship element is not usually insured, and reliant on the contractor continuing to trade, should defects need to be rectified. Insolvency insurance to cover workmanship can be arranged but this will usually incurs a separate premium to be paid direct to the insurer by the client.
Single point guarantees are often preferred by specifiers and building owners, as the responsibility for all the elements of the guarantee, including workmanship defects, material quality/performance issues and design input, is placed with the product manufacturer. If there is a problem with the roof during service, the client has only to call the manufacturer to get the matter resolved, regardless of whether the defect is material or workmanship related.
When a single point roofing guarantee is offered by the leading UK manufacturer of roofing and waterproofing materials, as in the case of IKO PLC, the assurance that this provides is of major value, and the additional peace of mind for the client is almost incalculable.
A single point guarantee can be a major factor in maximising the rental value of a property, as potential tenants will know that any roof problems will be rectified quickly. In addition, as the guarantee is fully transferable to a new owner, a single point guarantee can also have a significant and positive impact on the final sale value of a property.
In addition, the single point guarantee offered by IKO PLC is insurance backed, making it one of the best the best all round guarantee packages available on the market.
