Case Study

Bagnall Heights

A full roof replacement for an occupied retirement village using Danum TLE tiles, designed to improve airflow, moisture control, and long-term comfort.

Bagnall Heights is an independent-living retirement village comprising single-storey bungalows. Following historic, issues with the roof (tail vents and partial fixes), the estate needed a coordinated re-roof to address poor ventilation, localised leaks, and inconsistent detailing, while keeping disruption, dust and noise to a minimum for vulnerable residents.

The estate faced a combination of technical and logistical challenges. The original roofs had under-ventilated eaves and ridges, with no soffit vents at the eaves and ridge tiles that were not fully mortared or vented. Airflow through the roof spaces had also been compromised by incorrectly installed loft insulation, which restricted ventilation pathways.

Working in a live, sensitive environment required a safe and well-organised approach. Every stage of the work had to be carefully sequenced around the residents’ needs, maintaining clean, accessible routes at all times. Cost control was also a key factor, the chosen solution needed to strike the right balance between value, quality, and long-term performance.

A robust, labour-efficient roof system built around Danum TLE tiles. The Danum TLE specified as a practical alternative to Sandtoft wienerberger 20/20 tiles. The contractor favoured Danum due to the reduced amount of tiles required per m2, fewer cuts, and straightforward setting-out—helping reduce labour time and waste.

Performance in handling & install: Reported lower breakages in transit and on-roof; a robust weather bar that felt much more resilient to foot traffic.
Profile & aesthetics: Preferred ridge profile and a clean, slimmer appearance for a neat, consistent finish across the bungalow roofs.

“We choose Sandtoft Danum roof tiles for their sleek, slimline profile and the efficiency of the supply chain behind them — together delivering a clean, contemporary look that enhances the overall appearance of any roof.” - Bagnall Heights

Ventilation strategy: Introduction of continuous eaves ventilation and a ventilated ridge line to restore through-roof airflow, supported by corrected loft insulation detailing to maintain clear pathways.
Site management: Works area securely segregated; dust and noise carefully managed. Daily housekeeping to keep access routes clean and safe.

The Danum TLE tiles provided significant advantages in terms of labour efficiency and long-term durability. Its simple gauge and installation method allowed faster progress and reduced complexity on site. The tiles’ strength offered reassurance of long-term performance, while their colour and profile matched the estate’s existing aesthetic, This all helped to achieve a consistent, cohesive finish that complemented the village’s appearance.

“Small leaks gone,

looks smart, and you can feel the fresh air path working.” - Resident, Bagnall Heights

Close coordination between all parties was essential to the project’s success. The client and estate management team, led by Vicky and the ownership group at Bagnall Heights, worked closely with the contractor to plan the works in carefully managed phases, ensuring minimal disruption to residents.

SIG Merchant supplied the Danum TLE tiles along with all necessary fittings and accessories, keeping procurement streamlined and cost-efficient. On site, clear communication with residents was prioritised. Regular notices were issued, safe access was maintained, and welfare considerations were embedded in daily planning. This open and respectful approach helped build confidence and trust throughout the project.

The completed re-roof has delivered lasting improvements for the estate and its residents. Corrected eaves and ridge ventilation, together with improved insulation detailing, have restored healthy airflow through the roofs and residents have already reported fresher attic spaces and improved indoor comfort.

All localised leaks were resolved, and the ridge and verge lines now display a neat, consistent finish. The works were completed with zero incidents, maintaining a clean and well-managed site throughout.

Feedback from residents has been overwhelmingly positive, with many commenting on the tidy appearance and considerate conduct of the team. As one resident put it, “Small leaks gone, looks smart, and you can feel the fresh air path working.”
