What Factors Affect Replacement Conservatory Roof Cost?

Replacement conservatory roof cost will vary a great deal due to size, style and the chosen material. Size is the obvious factor when considering the replacement conservatory roof cost.

The bigger the replacement conservatory roof, the more material will be used, whether that be glass, polycarbonate, or a solid tiled conservatory roof. If you are considering replacing the window frames as well as the conservatory roof, then the replacement conservatory roof cost would obviously rise.

The replacement conservatory roof cost will differ depending on the style of replacement conservatory roof that you decide on. There are several different style of conservatories, some more complex than others and requiring more labour and material.

A Lean-to conservatory is the most basic of design and therefore a replacement conservatory roof cost is much lower than other roof types usually because of its simplicity.

A Victorian Conservatory features a multi faceted front window and a more complex shape than a Lean-to, so the replacement conservatory roof would naturally be more. A victorian conservatory consists of multiple panels (glass or polycarbonate), and frames, also the curved end bay window means that costs involved and labour time would be more, therefore price would be more than a simpler design. Price could be lowered by choosing Polycarbonate rather than glass, materials make a difference to price but also performance.

Note that a polycarbonate replacement conservatory roof cost much less than the same roof with double or triple glazed glass panels, which in turn cost less than a tiled replacement conservatory roof or a solid roof such as a warm roof with GRP finish. Frame material also plays a part in the replacement conservatory roof cost.

If you purchase uPVC frames, you will save on the replacement conservatory roof costs, uPVC is less expensive than either aluminium or timber frames. The frame price difference is usually around 30% and 50% more expensive than uPVC respectively which is amassive difference when you consider the amount of frames in a conservatory.

Whats The Difference In Replacement Conservatory Roof Cost for Polycarbonate and Glass Roofs?

Polycarbonate replacement conservatory roof: It goes without saying that the polycarbonate roof would be the lowest priced replacment conservatory roof you can buy. The pros of a polycarbonate replacement conservatory roof are the light-weight and UV filter. The cons to a polycarbonate replacement conservatory roof are the poor insulation from environmental noise and also the thermal insulation is very poor. The lifespan of polycarbonate conservatory roofs is not as long as other materials and needs replacing often.

Glass replacement conservatory roof: A glass roof is more expensive than its polycarbonate counterpart, it lets in more natural sunlight than polycarbonate, however this does have its drawbacks during the summer if you do not have roof blinds installed. A glass roof will have better insulation with double or even triple glazing, and there is an option to have tinted glass which filters out the sunlight. Glass would not need replacing as often as polycarbonate conservatory roofs.

As you can see a Glass replacement conservatory roof would be the better choice in most cases, longer lifespan, better insulation, but what about the replacement conservatory roof cost …..
A polycarbonate lean-to roof 3000mm x 3000mm would be roughly £2,450 to £2,800 approximately. The replacement conservatory roof cost of a glass roof of the same size would be around £2,750 to £3,175 approximately.

All of these benefits mean a higher price tag. There are a lot of companies offering solid roof and tiled roof conservatory replacement roofs, needless to say some are of a much better quality than others which obviously affects the replacement conservatory roof costs for both solid or tiled conservatory roof replacements.

For a small size conservatory you should expect to pay at least £4,000. For a larger size conservatory, the replacement conservatory roof cost can start at £6,000.

When you find yourself trying to work out how much a replacement conservatory roof cost would be, you need to make sure you know exactly what style of roof you want, and whether it is possible and permissible.
So ask yourself what style of conservatory roof do you currently have? What style of replacement conservatory roof do you want? If the replacement conservatory roof style you want is different to your exisiting conservatory roof, can the new style be installed to your property?

A replacement conservatory roof doesn’t actually require any planning permission, however your new replacement conservatory roof must not be higher than the highest point of the roof on the house.

Another factor to consider is that the foundation needs to be able to adequate to hold the weight of the replacement conservatory roof. This is another reason why we only supply and install Ultraroof tiled conservatory roofs as they are the lightest and strongest on the market.

The replacement conservatory roof design will certainly be a key factor in the replacement conservatory roof cost. A lean-to roof which is the simplest conservatory roof will cost far less than a more complex design such as a Victorian or Edwardian style conservatory.
