Types of Conservatory Roofs
Conservatories may have glass, polycarbonate, or tiled roofs. Each option differs in appearance, performance, and cost. Tiled, solid roofs could also have some additional costs. One thing you’ll need to consider here is conservatory roof insulation cost, since it’ll make your conservatory a much more comfortable space whilst saving you money, too.
Glass Roofs
Glass conservatory roofs provide an elegant look with plenty of natural light. The glass is available toughened or laminated for safety and insulation depending on your needs. With glass, however, you should expect to pay more compared to other materials as replacement conservatory roofs made of glass will likely need to be designed and cut to exact specifications.
Polycarbonate Roofs
Polycarbonate conservatory roofs are affordable, durable, and lightweight. They’re the cheapest conservatory roof option and in many cases are also probably the material your existing roof is using. The material is an excellent insulator also protecting against UV rays, they aren’t, however, known for their thermal performance so this could be a great opportunity to upgrade your old roof with a new material that performs incredibly well.
Other Roofing Materials
Some conservatories have tiled or slate roofs matching the main house roof. These blend with your property but reduce light levels and can add substantial weight requiring a robust frame. They do, however, offer a more robust installation and the new roof can feel much more a part of the home than your existing conservatory. Tiled roofs can be some of the most visually impressive too.
Factors Affecting Conservatory Roof Cost
When estimating your conservatory roof cost, you’ll need to consider:
Size and Shape
Larger and more complex designs require more materials and labour to install, increasing prices. A simple lean-to is the most affordable shape but many homeowners prefer more complex conservatory designs like p-shaped or l-shaped conservatories.
Materials
As shown above, glass is more expensive than (some) tiled and (all) polycarbonate roofs, with polycarbonate roofs being the cheapest of them all. Also, consider thickness, coating, thermal performance and special glass types (e.g. self-cleaning), which all add to the final price you’ll pay.
Special Features
Add-ons like roof vents, automatic openers, blinds and lighting increase costs. Manage your budget by identifying must-have or nice-to-have features and determining what’s really needed to make your conservatory a comfortable, enjoyable space.
Access Issues
Restricted access can mean additional labour costs for installation. This may apply for higher conservatories or awkward spaces. Discuss access with your installer to ensure they can actually carry out their work effectively without too many complications.
Average Cost by Conservatory Roof Type
To budget for your new conservatory roof, check typical supply and install costs before choosing a conservatory roof specialist to carry out the work.
Glass Roofs
Glass conservatory roofs range from £185 to £500 per m2. Tempered glass is the cheaper option from £185/m2 but might not be to everyone’s taste or thermal requirements. Higher performance laminated or double glazed units cost £300 to £500/m2. They’ll help you save on your energy bills long term, meaning some of that cost is recuperated, but there’s no denying that the upfront cost can be significant for the best performing glass conservatory roof options.
Polycarbonate Roofs
Polycarbonate conservatory roofs costs range from £120 to £250 per m2. Hollow polycarbonate sheets start around £120/m2. The best insulated solid and triple-wall polycarbonate options cost up to £250/m2. It’s worth noting though that a polycarbonate conservatory roof will be much cheaper than the other materials, but even with triple-wall polycarbonate and the latest innovations these conservatory roof styles can’t compete with tiled, solid, or glass roofs when it comes to thermal performance and energy efficiency.
Tiled Roofs
A tiled conservatory roof costs £300 to £700 per m2 installed. Concrete tiles are more affordable at around £300/m2. For slate tiles, expect to pay £500 to £700/m2. Slate is more expensive because it’s a higher-end tile finish and adds a lot more aesthetic appeal than simple concrete options.
Getting Accurate Quotes
To get precise conservatory roof quotes, ensure you provide:
Measurements
Supply exact dimensions rather than estimates so you receive accurate material costs. Consider internal and external dimensions to provide the most information upfront and to be as clear as possible. An accurate estimate is still better than a shot in the dark, it just means your quoted price might be off slightly.
Material and Build Specifications
Choose your preferred materials and finishes. Provide details like glazing type, ventilation needs, colour and additional features to get an accurate quote for your complete conservatory roof replacement.
Additional Works
Have a think about if you need other works like electrics, plastering or decorating after the roof has been replaced. This prevents budget surprises after you receive your quote through us for the roof alone.
Our network of conservatory roof installers are all vetted to ensure they have the right qualifications and reputation to carry out top-quality work. And better yet, they offer some of the most competitive prices on the market. Consider the information above and then apply for a quote today to get an accurate estimated cost for your conservatory roof project.
Potential Additional Costs
Alongside the roof build, factor in expenses like:
Base Works
The conservatory roof frame rests on a conservatory base which may require extension, reinforcement or replacement at extra cost. Not all conservatory bases are capable of supporting the weight of a new roof, so some work may be required to ensure you get the final conservatory you’re hoping for.
Electrics
Power and lighting typically adds £500+ to the job. You may also want heating, speakers or smart controls depending on how you plan to use the space. This all adds to the final price you’ll pay.
Furnishings
Furnishing the new space with flooring, drapes, furniture etc can easily amount to several thousand pounds depending on the finish you’re looking for and the way you’re using the space. You might not consider furnishings straight away, but they will need thinking about eventually and they’ll come at an additional cost.
Ongoing Maintenance Estimates
Future maintenance is essential to enjoy your conservatory long-term and again, this all needs to be considered to understand the true cost of your conservatory roof replacement over time:
Cleaning
For glass and polycarbonate roofs, allow around £250 annually for specialist external and internal cleaning to keep your new roof looking and performing at its best.
Repairs
Repair costs will vary depending on any storm, fall or accidental damage that might happen. Inspect annually and fix minor issues immediately to avoid bigger problems. An annual repair budget of £150 can help cover eventualities.
Replacements
Expect to replace polycarbonate panels every 8-10 years (£150+ each), with glass units lasting at least 25 years if properly maintained. Tiled conservatory roofs can last even longer when cared for in the right way.
