Frequently Asked Questions

Yes, in warm roof systems, a minimum 13mm thick layer of IKO Permascreed laid on IKO Glass Fibre Tissue separating lauyer will act as an effective VCL.

The only roofing solutions that can be installed in ‘wet’ weather are those that are viewed as emergency roof repair compounds such as IKOpro Emergency Roof Repair, with the intention of undertaking further comprehensive or replacement works when the conditions are dry.

Installations in cold weather are dependent on many factors such as the types of IKO products / systems that are being considers and the air and surface temperatures being experienced on-site. For further information on specific product installation parameters please check the Technical Data Sheet (TDS) or contact the IKO Technical Department on 00353 (0) 1 8855090 or email waterproofing@iko.ie

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 Ltd) 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.

The duration period that IKO warranties cover ranges from 10 – 25 years depending on product and application. Subcontractor insolvency is available on their ‘Insured System Guarantee’. There are no charges for the various warranty types offered by IKO.

Organisational Commercial and Technical Support:

At Tender and Preconstruction stage:

• Regionally based area business manager who can assess technical drawings, advise on specific requirements and offer individual solutions for any given project. IKO area business managers can also survey existing buildings to ensure that your refurbishment scheme is ideally suited to the requirements of the project. This includes producing written reports, specifications, CAD drawings and thermal calculations.
• A trained and experienced Technical Services Team with over 100 years’ relevant experience who can deal with the specific needs of the professional roofing specifier and roofing contractor, responding accurately and rapidly to inquiries via fax, phone, email or letter.

At Construction and Post Construction stage IKO will offer:

• Regular monitoring of all projects during installation to maintain full specification compliance, and ensure that any site queries are handled quickly and effectively. This will always include attendance at a pre-start meeting and a guarantee sign-off inspection, with interim inspections and reporting measures as required. All members of the IKO technical site team are fully trained and CSCS registered. All IKO site reports are electronically recorded with a photographic record of each visit and issued to all parties.

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.
