Modern Polycarbonate Roofing

Polycarbonate Conservatory Roof Panels – Lightweight, Affordable, and Versatile In areas like Poole, Christchurch, and across Dorset, polycarbonate remains one of the most popular conservatory roofing materials for homeowners looking to upgrade without overspending. Modern polycarbonate conservatory roof panels are available in thicknesses from 10mm to 35mm, with 25mm and 35mm being the most commonly installed across the South Coast. Most professional installers—including our Conservatory MOT team—won’t recommend anything under 25mm due to reduced thermal performance. There are five main colour and finish options: Clear Opal Bronze Bronze & Opal (dual-tone) HeatGuard (also called SolarGuard) HeatGuard features a reflective silver-grey outer layer designed to reduce heat absorption—perfect for sunny locations along the Jurassic Coast. It’s available in both 25mm and 35mm panels. The clear finish provides the most light but has the highest U-value (i.e. lower insulation), while 35mm HeatGuard offers the best energy performance and glare reduction—rivaling double-glazed glass panels at a much lower cost. One consideration with polycarbonate is rain noise. However, 35mm panels offer a noticeable improvement, cutting noise levels by up to 40% compared to 25mm. If complete sound insulation is a priority, modern glass roofs remain the quietest option.

Flat Roofs – A Modern & Practical Roofing Solution

A flat conservatory roof is a versatile, contemporary solution for upgrading existing conservatories, new extensions, or garden rooms. Popular across Poole, Bournemouth, and surrounding Dorset areas, this style offers a clean, minimalist aesthetic with outstanding thermal performance and durability. Why Choose a Flat Roof? Sleek & Contemporary – Ideal for modern home extensions with a minimalist feel. Strong & Durable – Built to last using high-performance insulated panels. Better Insulation – Helps maintain stable indoor temperatures all year round. Optional Rooflights or Lanterns – Add privacy, natural daylight, and a touch of design flair. Low Maintenance – Fewer external components make upkeep simple. Planning Permission Notes: Flat roof upgrades may require additional approvals when replacing a traditional pitched roof. Our Conservatory MOT team will guide you through this, ensuring all regulations are handled quickly and smoothly. Flat Living Roofs create a seamless connection between your conservatory and main home—delivering a practical, energy-efficient space without compromising on style.

Upgrade Your Conservatory Roof the Smart Way

Upgrading your conservatory roof isn’t just the No. 1 improvement—it’s the foundation for better insulation, energy efficiency, and year-round comfort. Most homeowners don’t realize that starting at the top solves multiple issues in one go. And from a builder’s perspective, sealing up the envelope begins with the roof—it’s the first and most important step to making any conservatory space truly efficient.


Why Upgrade?

Regulate Temperature – Stay cool in summer and warm in winter.

Improve Insulation – Reduce energy costs with better heat retention.

Minimize Noise – Enjoy a quieter, more peaceful space.

Replace Worn Parts – There’s more to a conservatory roof than meets the eye. Hidden components like glazing bars, seals, and support trims all affect long-term performance and comfort.

Budget-Friendly Options – From polycarbonate to hybrid and tiled systems, there’s a solution to suit every budget.

This conservatory roof is an Orangery design

Orangery Roof – A Timeless & Elegant Upgrade

An orangery roof is more than just a roofing option—it’s a design statement that enhances both style and structure. Unlike standard conservatories, an orangery incorporates solid architectural elements, blending seamlessly with your home to create a more permanent and substantial living space. Traditional brick or decorative piers at the corners provide structural strength while giving the orangery a high-end aesthetic that feels more like a true extension of your home rather than a simple add-on. KEY FEATURES

Key Features of an Orangery Roof:

 Grand Architectural Design – A wider insulated beam and soffit give the roofline a refined, elegant look. 

Central Glass Roof – Allows natural light to flood the space while maintaining the warmth and coziness of a solid structure.
 

Structural Piers – Brick or decorative piers at the corners enhance stability and create a more permanent extension feel. 

Thermal Efficiency – More insulated than a traditional conservatory roof, keeping your space comfortable all year.


 Versatile Styling – Available in modern or traditional designs, with the option to include lantern roofs or decorative cornices.


Minimal Approvals Required – Like LivinRoof, most orangery designs do not need additional planning permissions or fees.

A Blend of Light & Structure

Orangery roofs provide the perfect balance between open, light-filled spaces and solid, well-insulated structures. The combination of large glazed panels with a solid perimeter roof makes them an excellent choice for those who want more privacy and insulation while still enjoying natural daylight.

Unlike traditional conservatories, an orangery feels like a true home extension rather than a separate room. Whether you are renovating an older conservatory or building from scratch, an orangery-style roof delivers elegance, warmth, and long-term value to your property.

Customization & Integration
Orangeries are highly customizable, allowing homeowners to personalize their design with:

Roof lanterns or multiple glazed sections to optimize light.

Modern or classical decorative elements to suit any home style.

High-performance glazing to further enhance insulation and reduce glare.

With their distinctive charm and superior comfort, orangeries are an investment in lifestyle and property value, offering a sophisticated yet practical solution for modern living.
