Looking to expand the size of their house it is not uncommon to build an extension. It is easy to forget the importance of choosing the right type of roof extension to go on top of it. There are a number of reasons why it is important to take this seemingly innocuous aspect into consideration. But first lets look at why someone might build an extension in the first place.

Many people who have managed to save or have come into some unexpected money find themselves having to make a decision. Feeling they need more space in their house their first impulse is to move into a new home. However, moving home is no small decision. There are so many factors to consider. Cost is one thing. Even if the new home only costs slightly more than the price they get for the old one there are plenty of requirements that cost a huge amount of money.

Beyond the obvious cost of hiring moving companies and income lost from having to take time off work to pack, supervise the move and unpack there are also a number of hidden costs in the process of buying and selling a house. The lawyers who draw up the documents will need a cut, the realtor who organised the sale will want a share and of course the tax man will need to take his share too. That added space with a roof extension on it is starting to look pretty good about now.

Apart from the financial costs there are other things to take on board when considering a move not least of all community. The friends and neighbours you have built up friends and relationships with over the years are no longer going to be just a short walk away. Its clear that if extra space is all a person needs for their house then an extension is the way to go.

Even when the simple decision has been made to build an extension there are still a few important decisions to be made about how it is to be built. Let's say a person wants a simple sun room or conservatory built on their house, one of the first things they need to decide is how high they want it to be. The height of an extension can make the difference between whether an extension gets built at all. Once an extension goes over a certain height it is subject to planning permission. Also if the roof extension blocks a neighbours view it is likely to be refused planning permission.

In this case the option of a lightweight roof extension should be considered. The lighter the material that the roof is made from the lower the pitch of the roof extension can be. A roof extension with a low pitch provides greater internal height to the extension. Insulation is another factor that has to be balanced against the lightness of the roof extension material. Particularly with conservatories where a lot of heat can be lost an extension roof with high insulation value can lead to substantial savings on energy costs. It is important then to find an roof extension that has high insulation value along with low weight.
