skylight/rooflight

[Oilyboy]

I want to construct a skylight/rooflight for a flat roof. I wonder if anyone has a plan/drawing for one. Thanks

You can get them pre-built, all ready to install, in a variety of sizes and styles.

The walls and lip that goes under the roof coating have to be watertight, bond with the coating and flex a little with it whilst remaining watertight - which basically means plastic, aluminium or fibreglass. They typically have a three part seal to ensure that water cannot get past into the roof structure.

Unless you are in to making up your own fibreglass moulds or a bit of aluminium welding, then buying a pre-built one is probably best..

Its a bit cheeky to some companies but when i have done construction on things like skylights i get an idea of the one i want to go for first then get in touch with a company and ask for the fitting instructions which usually gives all the dimensions.Most skylight/rooflights are very similar in build but some have a very slight difference that you need to accomodate into your plans.Mind you the net makes it easier as a fair number of companies now put a PDF download on their sites of fitting instructions which gives a good idea.Shop around first though online to see which ones you like,then get a copy of their instructions.Dont start cutting out things before you have the specific detailing otherwise thats when you end up in trouble.

Good luck.
