Q. Who can install my rooflight?

A. The CLEMENT Conservation rooflight is a supply only product. Installing any rooflight is a specialist job so it is important for you to consult a chartered builder or surveyor before undertaking the project. Detailed installation instructions come with every rooflight. We can not recommend installers, however here are individuals who have experience of installing our products:

Andrew Booton Midlands. Tel: 07887 714134

Q. Will I need a flashing kit?

A. We would always suggest you consult your roofer as every roof is different. As a general guide we recommend you use a Code 5 lead flashing for bottom apron, Code 3 for the top apron and lead soakers.

Q. What about condensation?

A. Condensation is possible but very unlikely with the thermal efficiency of the argon gas filled double glazed units of the CLEMENT conservation rooflight combined with the thermal shield and thermally broken ‘T’ glazing bar, which comes as standard. Please ensure that the entire fitting is in accordance with our installation instructions and Part F of the Building Regulations.

Q. What roof pitches are your rooflights suitable for?

A. Our rooflights have been tested between 30 and 70 degrees. If your roof pitch does not come into this category please ring us and we will advise you on the best option. If you wish we can do a simple drawing for you showing the detail.

Q. Can you rooflights be installed next to each other?

A. Yes as long as you have supporting rafters our rooflights can bepositioned right next to each other.

Q. I have a slate roof, does my rooflight need to be different?

Taking care of your Rooflight

Open and shut the rooflight, clean down the paint surface at least twice a year (polluted or marine environments will require more intensive maintenance) using warm water with a drop of washing up liquid. Keep the weatherstripping clean removing any grime, ensure the working parts remain dust free and regularly lubricated. If you plan to install the rooflight in a marine environment, please contact us on 01428 643393


We offer a 10 year warranty on the paint surface, 5 years for glass unit failure and 1 year fittings. In the event of any problem please contact us within 48 hours. All subject to our terms and conditions which you should read thoroughly. Copy available upon request or see the website.
