If you are planning an extension at your property you may be faced with the problem of bringing natural light into the new area for example if you cannot put a window into a new wall or you are converting part of your garage to extend your kitchen. The costs of any extension can rocket if there needs to be extra double-glazed windows installed so a roof light is a sensible alternative. The costs can be minimised further by installing a fixed unit rather than an opening one.
The major factor when installing a roof light in a roof is that it is adequately sealed to avoid any leaks due to rainwater. When purchasing the unit, the enclosed fitting instructions should be followed to ensure that the roof light is fitted correctly. It may be that you chose to employ someone to install the roof light for you as you will need to get access to the roof with either a ladder or scaffolding making the job more challenging for the average householder. In this case a reputable builder should be able to install the roof light for a reasonable cost.
Cleaning the glass is sometimes a worry for some people but recent developments in self-cleaning glass means that this is no longer a problem and should not deter you from installing this feature in your extension.
