New Roof Lantern & Flat Roof Installation in Farnham – 3×2m Solar Glass Lantern

Project Overview – Flat Roof Replacement.

Our team of professional roofers in Farnham, Surrey recently completed a full flat roof replacement alongside the installation of a bespoke 3m x 2m solar glass roof lantern.

The property, located in Farnham, required a modern roofing upgrade that would:

  • Improve natural light levels

  • Increase energy efficiency

  • Provide long-term waterproof protection

  • Enhance the overall appearance of the extension

This project combined a three-layer torch-on mineral felt flat roofing system with a high-performance aluminium roof lantern featuring an integrated electric opener. Check out some of the systems capabilities here

Electric Roof Lantern Opener – Enhanced Ventilation

The integrated electric opener allows the homeowner to easily control airflow within the extension.

Benefits of the Opening Roof Lantern

  • Improved natural ventilation

  • Reduced condensation

  • Increased comfort during warmer months

  • Convenient remote operation

This feature is particularly beneficial for kitchen-diner extensions and open-plan living areas.

Results for the Farnham Homeowner

✔ Bright, modern living space
✔ Improved energy efficiency
✔ Durable, weatherproof flat roof system
✔ Enhanced property value
✔ Clean, contemporary external finish

The combination of a robust flat roof and premium roof lantern significantly improved both functionality and aesthetics.

Why We Chose a Torch-On Felt System

  • Exceptional waterproofing performance

  • Long lifespan (20+ years with correct maintenance)

  • UV-resistant mineral cap sheet finish

  • Ideal for residential extensions and garages

  • Proven reliability in Surrey weather conditions

Flat Roof Installation Process

  1. Full removal of existing flat roof coverings

  2. Inspection and reinforcement of roof decking

  3. Installation of high-performance underlay

  4. Application of reinforced intermediate layer

  5. Torch-bonded mineral cap sheet for long-term durability

  6. Professional sealing of edges, upstands and flashings

This system provides robust protection and remains one of the most popular choices for flat roof replacement in Farnham and surrounding Surrey villages.

Josh and his team have worked on several projects at our house, not least a new flat roof and large lantern. The boys were very friendly and polite - and importantly neat and tidy! Costings were very reasonable and work was carried out on time. It was also great that Josh was always available for a chat - unlike some contractors we have used in the past.

I recently had an extension built by Primary Construction, and I couldn't be happier with the results. From start to finish, their team was professional, efficient, and highly skilled. They worked with precision, ensuring every detail was completed to the highest standard.

The quality of the workmanship is outstanding, and the extension blends seamlessly with the existing structure. The team was always punctual, kept the site clean, and communicated clearly throughout the process, keeping me informed at every stage.

Not only did they complete the project on time, but they also stayed within budget with no hidden surprises. Their attention to detail and commitment to excellence truly set them apart.
