Roof & Gutter Sealant

About Roof & Gutter Sealant

Roof and gutter sealants are essential waterproofing products designed to protect buildings from water ingress, leaks, and weather damage. These specialised compounds create durable, flexible seals that prevent moisture from penetrating vulnerable areas of roofing systems, guttering, flashings, and drainage components. Whether you're dealing with emergency repairs during a downpour or planning preventative maintenance, quality sealants can save thousands of pounds in potential water damage whilst extending the lifespan of roofing systems.

MyToolShed.co.uk stocks a comprehensive range from Everbuild, a trusted British manufacturer renowned for professional-grade sealants and weatherproofing products. From liquid roof coatings like Aquaseal for large area coverage to cartridge-based solutions such as Evercryl for emergency repairs and Lead Mate for flashing work, our selection covers both planned maintenance and urgent repair scenarios across residential, commercial, and industrial applications.

• Agricultural workers repairing farm buildings, barns, and outbuildings

Choosing The Right Roof & Gutter Sealant

Selecting the appropriate sealant depends on several critical factors:

Application Type: Emergency repair products like Everbuild Evercryl can be applied in damp conditions, whilst standard sealants require dry substrates for optimal adhesion. Consider your timeline and weather conditions when selecting products.

Substrate Compatibility: Different formulations suit specific materials. Lead Mate products are designed for lead flashings, whilst general roof sealants work across slate, tile, concrete, and felt. Always verify compatibility before application.

Coverage Area: Liquid roof coatings in tins are economical for large areas and offer better value per square metre, whilst cartridge-based sealants provide precise application for joints, seams, and localised repairs without waste.

Weather Resistance: British weather demands products that withstand freeze-thaw cycles, UV exposure, and persistent moisture. MyToolShed.co.uk stocks sealants specifically tested for UK climate conditions with proven long-term flexibility.

Finish and Colour: For visible areas, select colours that blend with existing roofing materials. Many sealants are overpaintable once cured, offering flexibility for aesthetic matching on customer-facing projects.

Safety Information

Working at Height: Roof work falls under HSE guidelines. Use appropriate access equipment including properly secured ladders or scaffolding, and always use fall protection equipment when working above two metres.

Product Handling: Consult manufacturer safety data sheets before use. Many sealants contain solvents requiring adequate ventilation. Wear appropriate PPE including nitrile gloves and safety glasses to protect against skin contact and splashes.

Weather Conditions: Never work on roofs during high winds, rain, ice, or when surfaces are slippery. Personal safety must take precedence over completing repairs urgently.

Frequently Asked Questions

Can roof sealant be applied in wet weather?

Most standard roof sealants require dry conditions for proper adhesion, but emergency repair products like Everbuild Evercryl are specifically formulated to be applied even in damp conditions or light rain. However, standing water should always be removed before application, and dry conditions will always produce superior long-term results when possible.

How long does roof and gutter sealant last?

Quality roof sealants typically provide 5-10 years of effective weatherproofing when correctly applied to properly prepared surfaces. Lifespan depends on substrate preparation, application thickness, UV exposure, and weather severity. Regular inspection and minor touch-ups can extend service life significantly.

What's the difference between cartridge and liquid roof sealant?

Cartridge sealants are ideal for joints, seams, flashings, and localised repairs, offering precise application with minimal waste. Liquid roof sealants in tins are more economical for coating larger areas like flat roofs or extensive gutter repairs, applied with brush or roller for uniform coverage across square metres of surface.
