SINGLE PLY ROOFING
Single ply is a cost effective roofing solution.
What is Single Ply?
Single Ply remains one of the most popular and reliable flat roofing solutions for construction and refurbishment projects in the UK. Sage Roofing are experienced Single Ply roofing contractors and are approved installers for Sika, Alumasc, Bauder and IKO. We use two of the leading Sika brands, Sarnafil and Trocal.
It is a PVC or TPO membrane that can be mechanically fixed, bonded or ballasted. Single Ply roofing systems use flexible sheets of synthetic materials that are manufactured to strict requirements to ensure high quality. This type of roofing membrane is designed to give lasting durability and strength and has become an increasingly popular system for flat roofing.
SIKA SARNAFIL AND TROCAL SYSTEMS
Sarnafil and Trocal are cost effective quality products that can be laid quickly in almost all applications. It is recommended that single ply is laid to falls, the BBA recommendation is to aim at 1.5° fall to get 0.75° with building tolerances, however this can be expensive and cause height problems. Sarnafil and Trocal single ply have exactly the same guarantee whether laid to a fall or flat and our Sage warranty is also the same.
Mechanically fixed Sarnafil is not weather dependant and can be fixed all year round without the need for a naked flame during installation. However, adhered systems can only be laid in 5°C and surfaces need to be dry. Both systems will bond to concrete, screed and ply, and are available fleece backed for enhanced aesthetics. Subject to stock and minimum quality, Sarnafil and Trocal are available in a range of colours. Excellent air seal can be achieved with this roofing method and it offers a number of VCL/ air seal options.
Sika monitor their approved contractor network and remove under performers. Each system requires residential course training for staff and installers, and Sika write a technical specification for every project. Their field engineers check every installation for quality and inspect the final construction prior to sign off and approval of warranty, so you are guaranteed an excellent service when you choose an approved installer like Sage Roofing.
