How much does a new conservatory roof cost? A homeowner’s guide

If you’ve been Googling the cost of a new roof for a conservatory, you’ve probably already realised one thing, that there isn’t a single, fixed price, and that’s not us being vague. The truth is, every conservatory roof we install at Advanced Glazing Systems is bespoke. Your final conservatory roof cost depends on your choices.

In simple terms, the price of a replacement conservatory roof is shaped by:

• The type of roof you choose (solid, tiled, glass or combination)
• The material it’s made from
• The size of your conservatory
• How insulated you want it to be
• Any extras like roof lanterns or roof lights

Because we design each roof around your home, your budget and how you use the space, there’s always a solution, whether you’re looking for the most affordable option or more of a premium product, giving that luxury feel all year round.

In this guide, we’ll break down the main factors behind new conservatory roof costs, explain your options and help you plan a budget that makes sense for your home in Essex or London.

What impacts the cost of a new conservatory roof?

Several main factors shape the cost of a new roof for conservatory projects. Some you can’t change, like the size of the conservatory. Others are fully in your control, like the type of roof and the level of insulation.

Material

The material plays a huge part in determining the final cost of a new conservatory roof. Different materials suit different budgets and lifestyles.

Budget, mid-range and premium options

• Budget: Polycarbonate roofs
• Mid-range: Glass roofs
• Premium: Tiled and solid roof systems or combination roofs

Let’s look at the main materials on the market.

Polycarbonate roof

Polycarbonate was once the most popular choice for conservatories across the UK. It’s lightweight and affordable, making it the cheapest option.

However, it’s also:

• Poor at keeping heat in during winter
• Prone to overheating in summer
• Noisy when it rains
• Quite dated in appearance

Most homeowners now choose glass or solid roofs because they offer far better comfort and long-term value.

Tiled roof

A tiled conservatory roof is designed to turn your conservatory into a proper, year-round room. We specialise in the Equinox roof system, which is fully insulated, lightweight and extremely durable.

Benefits include:

• Warm in winter and cool in summer
• Much quieter in heavy rain
• Looks like a real extension
• Strong and long-lasting

Glass roof

Glass roofs are perfect if light is your top priority. Our glass roofs use toughened safety glass with special coatings that:

• Reduce glare
• Reflect heat in summer
• Keep warmth in during winter
• Stay cleaner for longer

Glass conservatory roof costs usually sit in the mid-range. They’re a great way to keep the open feel of a conservatory while improving comfort.

Combination roof

Some homeowners want the best of both worlds. Combination roofs mix solid panels with glass sections or roof windows.

This gives you:

• Excellent insulation properties
• More light than full solid
• A truly bespoke look

They often sit between glass and solid roofs in pricing.

Roof material comparison

Material	Best for	Benefits	Typical market
Polycarbonate	Tight budgets	Lightweight, low upfront cost	Budget
Glass	Bright spaces	Light, solar control, modern look	Mid-range
Tiled / solid	Year-round use	Warm, quiet, durable	Premium
Combination	Balanced design	Light + insulation	Mid to premium

Size

At Advanced Glazing Systems, every conservatory is made to measure. But the rule is simple: the bigger the conservatory roof, the more materials, labour and time are needed.

So:

• A small lean-to roof costs less
• A large P-shaped or Victorian roof costs more

The size of your conservatory is one of the biggest drivers of replacement conservatory roof costs.

Conservatory style

We can fit new roofs to all styles:

• Georgian
• Victorian
• Gable
• Lean-to
• P or T shape
• Orangeries

More complex shapes like Victorian or Edwardian styles can cost slightly more because they:

• Have more sections
• Need more cutting and fitting
• Take longer to install

Simpler lean-to designs are often lower-cost.

Insulation levels

Insulation is what turns a conservatory into a space you can use all year.

Better insulation means:

• Lower heat loss in winter
• Less overheating in summer
• Lower energy bills

Highly insulated solid roof systems like Equinox cost more at first, but they usually save money over time because you won’t need to blast the heating just to use the room.

Additional upgrades

Extras don’t usually make or break your budget, but they can gently raise the final price.

Roof lanterns

A roof lantern is a raised glazed structure that sits on a flat or solid roof.

Benefits:

• Brings in loads of natural light
• Makes rooms feel bigger
• Looks stunning inside and out

We install Korniche and Atlas lantern roofs with aluminium frames, great thermal performance and self-cleaning glass.

Roof lights

Flat roof lights are sleek glass panels fitted into flat or solid roofs.

They:

• Brighten darker rooms
• Reduce the need for lights during the day

They’re available in custom sizes and colours like white, grey and black.

Other upgrades

• Roof vents for airflow
• Spotlights in internal pelmets
• Solar control glass
• Self-cleaning glass

Colour

Colour doesn’t have a huge impact on cost, with our tiled roofs available in beautiful finishes like terracotta, dark brown, slate grey, anthracite grey, brick red, pewter grey, stone black, plum and much more!

What are the benefits of a new conservatory roof?

A new roof isn’t just about fixing leaks or draughts. It changes how you use your home.

Better thermal efficiency

Thermal efficiency simply means how well your roof keeps heat where you want it.

• Keeps warmth inside during winter
• Stops overheating in summer
• Makes the room usable all year

Lower energy bills

Because your room holds heat better, you don’t need as much heating. That means lower energy bills over time.

Year-round comfort

No more:

• Freezing mornings
• Sweaty afternoons
• Condensation on windows

Just a comfortable room, whatever the weather.

Durability

Modern solid roof systems are:

• Strong
• Weather-resistant
• Long-lasting

They’re built to deal with British weather.

Added home value

A comfortable, usable conservatory can increase property value and make your home more attractive to buyers.

Looks that last

New roofs improve:

• The outside of your home
• The inside feel of the room
• The overall style of your property

How much should you budget for a conservatory roof replacement?

Most homeowners fall into one of three groups:

• Looking for the cheapest option
• Wanting a balanced upgrade
• Wanting a full conversion

Your budget should reflect:

• How often you use the space
• Whether you want year-round use
• Your long-term plans for the house
