VELUX Curb Mount Skylights Installation by Moore Skylights Inc. – Durable, Energy-Efficient Skylight Solutions
A curb mounted skylight is precisely as its name suggests. It features a structural lumber frame that rises 5.5 inches above the roof surface, forming a robust curb. This wooden frame, known as the curb, is meticulously sealed to the roof using fasteners, a high-grade ice and water membrane, new surrounding shingles, and a VELUX flashing kit. Once the curb is sealed and watertight, the VELUX skylight is positioned on top of the curb. Subsequently, the skylight and the curb are securely fastened together to create a complete watertight seal. The "curb" option is widely regarded as one of the best and most commonly used options for skylight replacement. Curb mount skylights can be tailored to custom sizes and are suitable for almost all home situations. Additionally, they feature larger condensation gaskets, making them particularly effective in areas with higher condensation levels. Both curb mount and deck mount skylights come with extensive warranties, including a full 10-year warranty from Moore Skylights Inc. and a 20-year warranty from VELUX Canada for seal failure.

01
High Grade Ice and Water Membrane
The secret to ensuring your skylight remains fully water- and snow-tight is the installation of a high-quality ice and water membrane. This premium membrane is carefully applied around the skylight and onto the surrounding roof, forming a 100% watertight seal. It effectively prevents water infiltration, ice dams, and snow accumulation, providing maximum protection against leaks and damage. By installing a top-tier ice and water barrier, you not only extend the lifespan of your skylight but also improve the overall durability and energy efficiency of your roof, offering lasting protection and peace of mind.
