QUICK ANSWER:
To ensure a successful conservatory roof upgrade, you must verify that the installation is:
- Building-regulation-approved
- Backed by a professional structural and thermal assessment.
- Provided with a formal Completion Certificate.
- Capable of solving the issue of a room being “too hot or too cold.
Replacing your conservatory with a tiled roof is one of the best ways to turn a “seasonal room” into a year-round living space. However, as the popularity of these renovations grows, so does the number of substandard installations that fail to meet modern performance or compliance standards.
At Greenoak Concept and Design, we were recently contacted by a homeowner whose previous roof renovation had not delivered the results they expected. Despite investing in what they thought was a thermal upgrade, they were left with a room that was still freezing in winter, boiling in summer, and most worryingly, not up to code.
To help you avoid a similar experience and protect your investment, we’ve put together a ‘red flag’ guide to help you vet a conservatory roof replacement company before signing up.
Don’t Get Caught Out: Common Industry Red Flags
Unfortunately, the case we’ve highlighted isn’t an isolated incident. We are often called out to help homeowners who have invested in conservatory roof replacements that simply don’t work.
Based on our experiences assessing and fixing substandard installations, here are the warning signs you should look for:
Red flag 1: Limited Improvements in Thermal Efficiency
If you’ve paid for a “new” roof but the room is still freezing in the winter and like an oven in the summer, the insulation has failed. A quality roof should make the room comfortable the moment it is installed.
What to look for: Ask for a high-performance system, such as a SupaLite insulated roof. Make sure it includes breathable membranes and proper ventilation to keep the temperature steady year-round.
Red flag 2: Uncertainty around Building Regulations
Many providers claim their work is “compliant”, but fail to provide the paperwork to prove it. Without a formal certificate, you may even find it difficult to sell your home in the future.
What to look for: Make sure your contractor manages the entire Building Regulation process for you and hands over a formal Completion Certificate once the job is done.
Red flag 3: Skipping the Structural Assessment
A very common (and dangerous) shortcut is to install a new roof without first checking if the existing conservatory frames and foundations can actually hold the weight. This is how leaks and structural cracks start, leading to much more expensive repairs later on.
What to look for: A reputable installer should always conduct a full structural and thermal assessment of your current conservatory before any work begins.
Red flag 4: Lack of Business Transparency
Be cautious of companies that lack a stable, clear history or operate under multiple different names.
Some providers even use different “trading names” to hide a history of bad work, meaning if your roof fails, they might disappear, leaving your warranty worthless.
What to look for: Research the company’s background – Are they an established UK-based business that can be found on Companies House? Do they have a transparent portfolio of compliant work?
Case Study: Fixing a Failed Conservatory Renovation
We were recently contacted by a homeowner whose previous conservatory renovation, installed by another provider, had failed to deliver the comfort or compliance they expected. You can read the full case study here.
The problem:
The customer had previously spent money on a replacement roof, but the room was still a nightmare to live in. Following an independent assessment, it became clear that the installation didn’t meet modern building standards. It needed a complete, regulation-approved overhaul.
Our approach:
We began with a detailed survey and honest consultation to ensure the homeowners fully understood compliance requirements.
Our team:
- Conducted a full structural and thermal assessment of the existing conservatory.
- Reviewed all requirements under current UK Building Regulations.
- Designed a tailored replacement plan focused on long-term performance and certification.
The result:
We installed a fully compliant, insulated tiled conservatory roof. The new system featured a breathable membrane, high-spec insulation, and a lightweight tiled finish.
The homeowner saw immediate benefits:
- Significantly improved temperature regulation
- Reduced heat loss during colder months
- Increased year-round usability of the living space
- The confidence and peace of mind of having a Building Regulations Completion Certificate.
