Benefits of a Tiled Conservatory Roof

An uninsulated polycarbonate conservatory roof has a U-value of around 1.8–3.0 W/m²K — meaning heat escapes through it at a rate comparable to a single-glazed window. Our tiled roof system achieves a U-value of just 0.15 W/m²K, which is roughly ten times more efficient than even a modern A-rated window, and comparable to an insulated house wall.

In practical terms, a polycarbonate conservatory is almost impossible to heat efficiently in winter — any heat you put in escapes through the roof almost immediately. With our tiled roof, the insulation holds the heat inside the space so a single radiator or small electric heater can warm the room to a comfortable temperature and keep it there at a fraction of the running cost. Customers consistently tell us the conservatory has gone from a space they rush through with a coat on, to one they sit in comfortably throughout winter.

Customers consistently tell us the cost of heating the conservatory drops noticeably after installation — because the heat they generate actually stays in the room rather than disappearing through a polycarbonate ceiling.

Polycarbonate and glass conservatory roofs transmit solar radiation directly into the room, creating a greenhouse effect in warm weather. On a sunny summer day, a polycarbonate conservatory can reach 42°C or above — genuinely dangerous to spend time in, and completely unusable for working, relaxing, or entertaining.

A tiled roof eliminates the greenhouse effect entirely. Because there's no transparent or semi-transparent material, solar radiation cannot enter the room through the roof. The multi-layer insulation system above the ceiling also prevents conducted heat from passing through the structure. Rather than the extreme temperatures a polycarbonate roof produces, the room stays at a level that tracks the ambient outdoor temperature more closely — far cooler than the sweltering 40°C+ a polycarbonate conservatory reaches on a warm day.

This is perhaps the single biggest quality-of-life improvement. The room goes from something you avoid from May through September to one of the most comfortable rooms in the house — and unlike a polycarbonate conservatory, you won't need to open every window and door just to make it bearable.

Rain noise is one of the most commonly cited reasons that people stop using their conservatory. The drumming of rain on polycarbonate — particularly during heavy showers or hailstorms — makes it impossible to hear a conversation, watch television, or concentrate on work. Many customers tell us their conservatory effectively has only about four usable months per year as a result.

Our tiled roof system eliminates rain noise almost completely. The combination of the structural tile layer and breathable moisture barrier absorbs virtually all impact sound from rain — the same multi-layer construction used in standard house roofs. The contrast with polycarbonate is dramatic: customers who couldn't hold a conversation during a shower now report no perceptible difference from sitting in the main house.

If you've ever sat in a conservatory in heavy rain and had to raise your voice to be heard, you'll understand why this is such a significant benefit.

Polycarbonate and glass conservatory roofs transmit significant levels of UV radiation — even panels with UV coatings allow some UV through, and those coatings degrade over time. The result is furniture that fades and bleaches, carpets and rugs that discolour, wooden floors that lose their finish, curtains that weaken and tear, and even photographs or artwork on the walls that fade.

A solid tiled roof blocks UV radiation entirely — there is no transparent element through which UV can pass. Many customers who've replaced their roof are able to keep furniture, flooring, and furnishings in the conservatory without any concern about sun damage. Over a 10–15 year period, the cost of replacing faded or damaged furnishings can easily exceed the cost of the roof replacement itself.

Heating a polycarbonate conservatory is expensive and largely pointless: the heat you generate escapes through the roof almost as fast as you can produce it. A typical gas or electric heater running in a polycarbonate conservatory costs significantly more per hour than heating an equivalent room in the main house.

Because the roof no longer haemorrhages heat, a much smaller and cheaper heat source can maintain a comfortable temperature. Customers who previously ran a large electric or LPG heater just to take the edge off tell us they now use a single small radiator or none at all. Many report meaningful reductions in what they spend heating the conservatory — and some find they heat the room far less often because it holds warmth far longer once brought up to temperature.

Many customers also find they no longer need the electric or portable heater they previously relied on in the conservatory, removing it from their energy consumption entirely.

An uninsulated conservatory is typically excluded from a property's habitable floor area by estate agents and mortgage surveyors. It adds garden room value only — typically marginal. A fully insulated, year-round conservatory is treated differently: it is classified as usable living space and counted toward the property's floor area.

The logic is simple: a room you can use 12 months a year is worth more than one you can use for four. Buyers viewing a property in winter can immediately see whether a conservatory is a usable space or a cold, damp room you hurry through — and that perception affects what they're willing to pay.

Perhaps the most profound benefit isn't thermal — it's about how you use your home. Most customers who contact us are using their conservatory for perhaps 4 months of the year, between April and September, and even then only in reasonable weather. For the rest of the year it sits largely empty, used as a storage area or a room you rush through on the way to the garden.

After a roof replacement, the conservatory becomes genuinely useful 12 months a year. Many customers tell us it becomes their favourite room — a bright, comfortable dining area; a home office; a playroom; a second sitting room. The investment in the roof is repaid daily in the quality of the living space it creates.

Our customers frequently say variations of the same thing: "I wish we'd done it years ago."

All materials used in our tiled roof system are BBA (British Board of Agrément) certified, which requires independent testing for fire performance, structural integrity, and durability. The BBA is the UK's leading independent construction product testing authority, and BBA certification is required for many building control applications.

Our Eco Friendly tile system has been tested to withstand sustained wind speeds of up to 147mph — well in excess of anything experienced in the UK. The tiles are manufactured from recycled materials and are designed to last 40+ years with minimal maintenance. Fire performance data is available on request and is provided to building control as part of the installation documentation.
