Questions you may have about skylights

Q. Why is the roof pitch important for skylight installations?

A. Each of our flashing kits are engineered with specific pitch requirements. The roof pitch is important because it ensures that the roof has the proper slope to effectively drain water off of both the flashing and the skylight. The roof pitch and the roofing material used are both important in determining the type of flashing needed.

Q. Can I convert my fixed skylight into a venting one?

A. No. It would be necessary to replace the fixed skylight with a ventilating unit.

Q. What are the basic types of Skylights?


  • Fixed Skylights – glass is fixed in place, does not open or close.
  • Manual Venting Skylights – glass raises and lowers by crank or by pushing upward.
  • Electric Venting Skylights – glass raises and lowers by means of electric motor.
  • Tube Skylights – flexible tube runs between ceiling and roof, eliminating need to build a tunnel. Does not raise or lower.

Q. How much light will a rigid VELUX SUN TUNNEL™ skylight transmit?

A. A precise answer depends on many factors including the roof orientation (i.e. South is always best), tunnel length, tunnel angles, time of day, season of the year, etc. However, generally the 10 and 14-inch diameter TGR and TMR units are best for lighting up bathrooms, halls, walk-in closets and areas up to 10′ x 10′. The 22-inch diameter TCC or TGC model is perfect for lighting larger areas. The same size rigid tunnel will always transmit more light than a flexible tunnel of the same size, length and configuration.

Q. Will the VELUX SUN TUNNEL™ skylights help with the winter ‘blahs’?

A. Winter time means that lots of us get stuck indoors at home and work. Studies show that natural, full-spectrum sunlight greatly contributes to increased productivity in the workplace and to an overall feeling of well-being. Sunlight deprivation can lead to a condition that experts call “Seasonal Affective Disorder,” also known as S.A.D. or the winter blahs. By bringing light from the sun into your house, or home office, a VELUX SUN TUNNEL™ skylight can help you reduce the winter blahs.
