You have finally decided to replace your old glass or polycarbonate conservatory roof with a solid, insulated upgrade. You are ready to reclaim your space and lower your energy bills. But before you accept a quote, there is a hidden industry secret you need to know about.
When upgrading a conservatory to a permanent living space, the most important components are the ones you'll never see once the plaster is dry. Most modern "warm roofs" fall into two categories: Mass-produced aluminum kits or Bespoke timber-framed structures.
If you are only getting quotes for pre-fabricated kits, your new roof might be at risk of dampness, poor fit, and lower energy efficiency.
The Hidden Problems with Aluminum Kits
Many national brands and installers rely on factory-cut aluminum kits. While quick to assemble, they come with two major drawbacks for the homeowner:
The "Cold Bridge" Phenomenon: Aluminum Kits use metal, which is a natural conductor. Even with thermal breaks, aluminum rafters can allow external cold to travel toward the internal plasterboard. This is "Cold Bridging," and it is the leading cause of damp spots and ghosting lines on finished ceilings.
The "Forced Fit": Houses are rarely perfectly square, and older conservatories naturally settle over time. A kit is cut in a factory to "perfect" 90-degree angles. If your home is even slightly out of alignment, the kit must be "forced" to fit, often relying on expanding foam and heavy trims to hide the gaps.
The CBC Solution: Crafted On-Site, Built to Last
At Cheshire Bespoke Conservatories, we refuse to compromise on the bones of your build. We choose a "Site-Built" philosophy over pre-fabricated kits.
Here is why our bespoke, timber-framed roofs offer a vastly superior replacement for your conservatory:
Zero Condensation Risk: Timber is a natural insulator. By using C24-grade structural timber, we break the thermal bridge entirely, ensuring your ceiling remains bone-dry.
Superior Thermal Efficiency: Most pre-fabricated kits are engineered to meet a baseline U-value requirement of 0.18. By utilizing a 150mm PIR high-performance core, our builds typically achieve a U-value of 0.13 to 0.15. This makes our standard specification roughly 20% more efficient than the entry-level models of the UK's most famous kit brands.
A True, Sympathetic Fit: Instead of forcing a factory-cut box onto your unique home, we measure, cut, and craft your roof on-site. This results in a "sympathetic" fit that works with your building, not against it.
Premium Exterior Finish: We finish our roofs with Tapco Lightweight Slate, which provides the aesthetic of natural slate with a fraction of the weight. It is UV-resistant, Grade A fire-rated, and won't crack or delaminate.
Because we are the craftsmen on-site—not a franchise paying for a national brand name—we are able to invest your budget into better materials.
Do It Once, Do It Right
When you see a cheaper quote for a roof replacement, it is usually because vital insulation layers have been thinned out or removed entirely. At CBC, we don't offer "upgraded insulation" as an extra; we build it into the bones of the roof from day one.
A solid roof conversion isn't just a roof replacement; it's a structural home extension. Ensure you are investing in a product that will keep your home warm, dry, and beautiful for decades to come.
