Leka System — Trade Supply
Leka Conservatory
Roof Systems
Structurally tested lightweight tiled warm roofs, fabricated to your survey and supplied as complete kits — U-values from 0.12, installed in two to three days.
The Detail
The Warm Roof That
Ends Callbacks
The Leka replacement conservatory roof is a structurally tested composite tiled system at around 10–12% of the weight of the traditional glass roof it replaces — most existing frames accept the load, subject to survey, with no extra bracing.
NO aluminium, steel or timber anywhere in the structure — no condensation, no thermal bridging, no rot. The patented GRP framework (GB patent no. 2538540) has a higher tensile strength than steel by weight and complies with BS EN13706.
Every kit is fabricated to your site dimensions in our Liverpool facility, labelled for fit sequence, and delivered with the documentation Building Control wants to see.
Compatibility
Fits Most Frames
Compatible with most existing conservatories and new builds. The finished roof weighs only a little more than the glass it replaces — subject to survey, no structural steels needed.
Thermal
Comfort All Year
A solid insulated roof replaces glazing or polycarbonate — comfortable in summer and winter, fewer callbacks, and a ceiling ready for plaster skim and downlights.
Longevity
Built to Outlast
GRP doesn’t absorb moisture, twist or rot. Factory-cut Leka insulated boards mean less waste on site and a repeatable result on every job.
Why trade installers choose it
Why Installers Fit The
Leka Conservatory Roof
■Truly lightweight
Controls the loads on existing frames and foundations — most conversions need no reinforcement, subject to survey.
■Leka Insulated Board
Factory-cut boards cut waste and speed up the internal finish. ECO specifications can use standard plasterboard.
■Faster build speeds
MFA approval streamlines Building Control applications. Lightweight parts and a logical fit sequence get you weather-tight in days.
■Improved energy efficiency
Insulated outer sheets mean fewer roof bars, lower weight and stronger U-values — warm in January, cool in July.
