Top 5 Benefits of Installing a Tiled Roof

A pitched roof is a system of covering, fixings, battens, underlay, flashings, ventilation and drainage. Replacing isolated slates or tiles can be sensible when those adjoining components remain serviceable. This guide explains the practical checks a Bromley property owner should make before requesting or approving work.

Quick answer

A pitched roof is a system of covering, fixings, battens, underlay, flashings, ventilation and drainage. Replacing isolated slates or tiles can be sensible when those adjoining components remain serviceable.

tile in this decision

Clay and concrete tiles vary in weight, profile, minimum pitch and visual character. Structural suitability, compatible fittings and local appearance need to be checked before substitution.

How professional installation is planned

This is an overview for commissioning work, not instructions for climbing onto or constructing a roof. A competent contractor should plan access, temporary weather protection, stripping, substrate repairs, the complete new build-up and inspection of critical details.

• Confirm the existing structure and measured roof geometry
• Select a system compatible with pitch, deck, exposure and intended use
• Specify insulation, vapour control and ventilation as one build-up
• Detail eaves, verges, ridges, abutments, outlets and penetrations
• Plan scaffolding, edge protection, deliveries and waste
• Record concealed defects and agree variations before covering them
• Provide completion photographs, care information and written guarantee terms

What should be written into the quotation?

The covering name is not enough. The quotation should identify preparation, substrate, fixings or adhesives, insulation, ventilation, flashings, trims, drainage, access, disposal and responsibility for internal making good.

Treat installation as a sequence of hold points

A sensible programme pauses after strip-off and deck inspection, again after critical junctions are formed, and before completion. Photographs at those stages make hidden preparation and agreed details easier to verify.

• Pre-start specification agreed
• Substrate exposed and condition recorded
• Variations approved before covering
• Junctions photographed during construction
• Drainage and finish checked at handover

What should be inspected?

• Slipped, cracked, delaminating or missing coverings
• Fixing fatigue and repeated movement across the slope
• Ridges, hips, valleys, verges and abutments
• Underlay, battens and visible timber condition
• Ventilation and insulation at eaves and high level
• Matching materials and any conservation constraints

Junctions often matter more than the main roof area

London properties frequently combine an older pitched roof with later extensions, dormers or small flat areas. Water entry often occurs where systems meet, so the inspection should follow abutments, parapets, valleys and changes in level.

• Main covering and additions inspected together
• Parapets and shared junctions traced
• Drainage from upper roofs checked
• Earlier repairs identified where visible

Assume sheeted roofs and rooflights are fragile

Old sheets, corroded material and rooflights can fail without warning. Do not test them by standing on them. A competent contractor should identify fragile areas and plan platforms, protection and access that avoid loading them. The HSE roof-work guidance explains the main requirements and hazards.

Questions to ask in the quotation

• Is failure localised or widespread?
• Can replacement materials be matched?
• What underlay, batten and ventilation work is included?
• How will valleys, chimneys and abutments be treated?

Frequently asked questions

How are unexpected defects handled?

The quotation should identify likely concealed risks and a variation process. Ask for photographs and approval before additional work is covered or charged.

When is a local repair sensible?

A repair is easier to justify when the defect is isolated and surrounding material is sound. Repeated failure, widespread deterioration or damaged support layers can change that decision.

Can old slates, tiles or fittings be reused?

Sound material may sometimes be retained or reused, but condition, matching, breakage allowance and any planning constraints should be assessed before promising a quantity.

Discuss your roof with a local roofer
