Flashband

About Flashband

Flashband is a self-adhesive flashing tape designed to provide instant weatherproof sealing for roofing repairs, joints, and vulnerable areas exposed to the British climate. Consisting of a bitumen-based compound with a durable aluminium or polyester surface layer, this versatile material creates an effective barrier against water ingress, wind, and general weathering without requiring specialist installation skills or heat application. MyToolShed.co.uk stocks trusted brands including Everbuild, Evo-Stik, and Denso, offering reliable solutions for both professional tradespeople and DIY enthusiasts.

Available in various widths from 75mm to 300mm, flashband can be easily cut to size and moulded to fit awkward shapes and contours around chimneys, guttering, conservatory roofs, and joints between different building materials. The pressure-sensitive adhesive backing bonds firmly to clean, dry surfaces, whilst primer application on porous materials ensures optimal adhesion and longevity. Many products come with extended guarantees when properly applied, making flashband a cost-effective alternative to traditional lead flashing methods.

Applications

Flashband is an essential weatherproofing product for a wide range of construction and maintenance professionals, including:

• Roofers performing repairs and installations on domestic and commercial properties
• General builders requiring quick weatherproofing during construction projects
• Property maintenance professionals and facilities managers
• Plumbers sealing around soil pipes, vent stacks, and roof penetrations
• Carpenters and joiners weatherproofing timber-to-masonry joints
• Window and conservatory fitters creating watertight seals
• Local authority maintenance teams carrying out repairs on council properties
• DIY homeowners tackling roofing repairs and home improvement projects

Choosing The Right Flashband

Surface Type: Identify your substrate material. Non-porous surfaces like metal, glass, and plastic generally don't require primer, whilst porous materials such as brick, concrete, timber, and roofing felt need primer application for proper adhesion and longevity.

Width and Coverage: Measure the area requiring coverage and select a width that provides adequate overlap on both sides. Wider rolls reduce installation time and minimise seams for larger applications.

Application Temperature: Most flashband products require temperatures above 5°C for proper adhesion. Check manufacturer specifications and avoid applying in wet conditions or when rain is forecast within 24 hours.

Quality and Lifespan: Premium products from brands stocked at MyToolShed.co.uk offer reinforced backing, superior bitumen compounds, and extended guarantees of 10-20 years. For critical applications or difficult-to-access areas, investing in higher-quality flashband reduces premature failure.

Safety Information

Flashband application often involves working at height on roofs or ladders. Ensure compliance with HSE guidance on working at height, using appropriate access equipment, edge protection, and fall arrest systems. Never work on roofs in wet, icy, or windy conditions. Wear protective gloves as bitumen-based materials can cause skin irritation. Ensure adequate ventilation when working in confined spaces, and check COSHH data sheets when using primers or solvents. Keep flashband away from naked flames and store in a cool, dry place away from direct sunlight.

Frequently Asked Questions

Do I need to use primer with flashband?

Primer is essential when applying flashband to porous surfaces such as brick, concrete, timber, and roofing felt. The primer seals the surface and significantly improves bond strength and longevity. Non-porous surfaces like metal and glass generally don't require primer, though they must be clean, dry, and free from contaminants.

How long does flashband last once installed?

When properly applied to correctly prepared surfaces, quality flashband products typically last 10-15 years or longer, with some premium products offering guarantees of up to 20 years. Lifespan depends on surface preparation, correct primer use, UV exposure, and temperature extremes.

Can flashband be painted over?

Yes, most flashband products can be painted once fully cured, typically after 24-48 hours. Use exterior-grade paint suitable for bitumen-based surfaces. Painting improves aesthetics and provides additional UV protection to extend the flashband's lifespan.
