It's totally understandable question. After all, how often does the average homeowner need to order flat roof skylights in their life? Not often.
It's worth taking the time to measure for the flat skylight properly, in order to avoid disputes and costly extra work. It's essential that you inform your builder / roofer clearly and correctly as to what size to build the timber kerb. Perhaps most importantly, and this is where it can go wrong, it's not just the width and length sizes that the builder / roofer needs, they also need to know whether those sizes they are being given are internal kerb or external kerb sizes.
Here's 3 simple steps to ensuring you have measured for your flat roof skylight correctly and that everyone is on the same page.
Step one
Find out from your architect or builder what size they had in mind for the flat roof skylight. On the other hand they might not know and ask for your input. In this case, decide on the rough size you think will work in your build.
Step two
Tell your builder the following: Our flat roof skylights are measured to the internal kerb size, and we recommend an 60mm deep timber kerb. You should also print off and give your builder / roofer this document. For example, a flat skylight 1m x 1m would require timber upstand that is 1m x 1m internal kerb size.
Step three
Order the skylight through us either through our website, over the phone or by email.
