Roofing & Guttering

Roofing & Guttering Supplies for Trade & DIY

At County Building Supplies, we supply roofing and guttering materials for professional roofers, builders, contractors, self-builders and DIY customers. Whether you're installing a new roof, repairing an existing structure or replacing damaged guttering, choosing the correct materials is essential for long-lasting weather protection and effective rainwater drainage.

Our range includes guttering, downpipes, roofing felt, lead flashing, roof battens, roofing ventilation, corrugated roofing sheets and soffit boards for a variety of residential and commercial projects.

Choosing the Right Roofing Materials

Different roofing projects require different materials depending on the roof construction, pitch and intended application.

• Roofing felt: Used in suitable roof covering and underlay systems to provide protection against moisture and weather exposure.
• Roof battens: Timber battens used to support roof tiles and slates in compatible pitched roof constructions.
• Lead flashing: Used to create weather-resistant details around chimneys, roof junctions and other suitable roof penetrations.
• Sheet roofing: Corrugated roofing sheets provide a practical covering for suitable sheds, garages, outbuildings and other structures.
• Roofing ventilation: Products designed to support airflow within specified roof constructions and help manage condensation risk.

Always select roofing materials suitable for the roof design, exposure conditions and manufacturer's installation requirements.

Guttering, Downpipes & Rainwater Drainage

A correctly designed guttering system helps collect rainwater from the roof and direct it safely away from the building.

County stocks Brett Martin guttering and downpipes, including selected 112mm roundstyle guttering and 68mm round downpipe products, alongside brackets, outlets, bends, stopends and other fittings.

When choosing guttering, consider the roof area, expected rainfall, gutter profile, downpipe capacity and compatibility between components.

Roofing Felt, Flashing & Weather Protection

Roofing felt and lead flashing are important components in many roof systems, helping manage water and protect vulnerable areas of the construction.

Roofing felt products vary according to their intended application, while lead flashing is commonly used around chimneys, abutments and roof junctions.

Choose products according to the roof specification and follow the manufacturer's guidance on overlaps, fixing methods and weatherproof detailing.

Roof Ventilation & Soffit Boards

Roof ventilation helps manage moisture within suitable roof constructions. The correct ventilation arrangement depends on the roof design, insulation position and condensation-control requirements.

Soffit boards provide a finish beneath the roof overhang and may form part of the roof ventilation arrangement where suitable vents are incorporated.

Always consider ventilation, insulation and moisture control together rather than selecting individual products in isolation.

How Much Roofing & Guttering Material Do You Need?

For roofing materials, measure the relevant roof dimensions and calculate the required area, taking account of roof pitch, overlaps, cutting waste and the manufacturer's stated coverage.

For guttering, measure the lengths of the roof edges requiring drainage and identify the necessary outlets, corners, brackets, stopends and downpipes.

Check the manufacturer's recommended fixing centres and system capacity before ordering.
