Clapham Conservatory Roof Replacements: Glass to Solid Tiled Roofs

Replacing a glazed or polycarbonate conservatory roof with a solid system is more than changing the outer covering. The existing structure, additional weight, insulation, ventilation, drainage and approvals all need to be considered together. This guide explains the practical checks a Clapham property owner should make before requesting or approving work.

Quick answer

Replacing a glazed or polycarbonate conservatory roof with a solid system is more than changing the outer covering. The existing structure, additional weight, insulation, ventilation, drainage and approvals all need to be considered together.

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.

The main decision this article should support

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.

• Roof pitch, spans and structural calculations
• Insulation continuity and condensation control
• Eaves, abutments, flashings and rainwater drainage
• Who confirms structural suitability?
• What insulation and ventilation build-up is specified?

What should be inspected?

• Whether the existing frames and foundations can support the proposed system
• Roof pitch, spans and structural calculations
• Insulation continuity and condensation control
• Eaves, abutments, flashings and rainwater drainage
• Planning and building-control requirements
• Internal ceiling, electrics and making-good responsibilities

Access can change the repair method

Terraced and converted properties can have different access at the front and rear. The quotation should say whether scaffold, a tower or another planned system is assumed, and how materials and waste will move without damaging occupied areas.

• Front and rear access considered separately
• Shared routes agreed before work
• Protection below the work included
• Parking and delivery assumptions recorded

Plan access before the repair

A short task is still roof work. Safe access, edge protection and the condition of the surface should be decided before anyone climbs. Ladders are not a substitute for a planned working position, and gutters must not be used as supports. The HSE roof-work guidance explains the main requirements and hazards.

Questions to ask in the quotation

• Who confirms structural suitability?
• What insulation and ventilation build-up is specified?
• Are approvals and drawings included?
• How will junctions with the house be weatherproofed?

Frequently asked questions

Can work continue in bad weather?

That depends on the task and safe system. High winds, lightning, ice or heavy rain can prevent access and may make opening the roof inappropriate.

What information should I give the roofer?

Provide the property location, roof type if known, when the symptom occurs, safe photographs, access constraints and details of previous related repairs.

Does every roofing job require scaffolding?

No single access method fits every property. Height, duration, roof geometry, public areas and the task determine what safe access and edge protection are required.
