Upgrading your conservatory roof is a big step and with so many options out there, it’s important to know the differences so you can make the best choice for your home. Cheaper options, like “clad over” solutions, might seem appealing at first, but they often come with hidden downsides that could affect the safety and long-term value of your conservatory.
This blog will explain the various types of clad-over systems, the factors you should consider, and why choosing an experienced company like Greenoak Concept & Design Ltd is essential.
What is a Clad Over?
A “clad over” refers to the practice of adding new materials to your existing conservatory roof without removing the original structure. This kind of approach is often promoted as a quick and cheap alternative to a complete roof replacement. However, while it may seem convenient, clad-over solutions can introduce weight, thermal efficiency, and structural integrity issues.
The Four Types of Clad Over
There are four primary types of clad-over systems, each with its own characteristics and potential drawbacks.
- Internal Clad Over (Clad Under): This involves adding insulation and boarding inside the conservatory roof. Wooden battens are often attached to the internal bars, which are then filled with insulation and finished with plasterboard. While this may improve the overall appearance of the interior, it compromises the original structure and can lead to issues like condensation, dampness, and weakened bars.
- External Clad Over: External clad over involves attaching timber battens or plywood to the exterior of the conservatory roof and finishing it with imitation tiles. In many cases, the original glazing remains in place, leaving little room for insulation. This method often results in poor thermal performance and adds significant weight to the existing roof.
- External and Internal Clad Over: A combination of the two methods above, this approach involves insulating and cladding both the inside and outside of the roof. While glazing is sometimes removed, the risk of moisture ingress is high, particularly when plastic cladding is used for the interior. This method still relies on the original structure, which may not be designed to support the added weight.
- Solid Panel Clad Over: Solid panel clad-over systems involve replacing some of the original glazing with solid panels. While this offers better thermal insulation compared to other clad-over options, it can still add substantial weight to the roof structure and may not meet building regulations unless the original framework is also replaced.
Things You Should Consider
Thermal Efficiency
Clad-over systems often lack proper insulation, resulting in poor thermal performance. Ensure any roof solution you choose provides excellent energy efficiency with a U-value low enough to keep your conservatory comfortable year-round.
Warranty
A quality roof installation should come with a robust warranty. Look for a product with a fully transferable guarantee backed by insurance for at least 10 years, ensuring peace of mind for years to come.
Condensation
Clad-over roofs can create condensation issues due to insufficient thermal barriers, leading to dampness, cracking plaster, or even electrical risks. Always check how the chosen system prevents condensation.
Structural Integrity
Your conservatory roof must handle heavy snow, strong winds, and additional weight safely. Ask for structural calculations and verify that the system complies with local building regulations to ensure long-term durability.
Weight
Clad-over solutions can add significant weight to the existing structure, potentially exceeding the limits it was designed to bear. Choose a lightweight solid roof system engineered for replacement conservatories to avoid damage.
