Installation Process

Expert installation made easy.

VELUX® skylight systems and Sun Tunnel® Skylights can be installed in flat or vaulted ceilings in two worry-free phases: rooftop and interior. The pros will recommend where skylight systems should be installed, so you can reap the maximum benefit from the natural light and fresh air they provide.

Installation Types

The Room

VELUX-trained pros will come inside for interior finish work and possible painting. If you have a flat ceiling, your installer will use drywall or other finish material to build a shaft from the skylight to direct the daylight into the room. This phase takes around half a day per skylight.

The Rooftop

VELUX-trained pros will cut a hole and fasten the VELUX skylight to the roof with three layers of protection to prevent leaks. Depending on the circumstances such as roof pitch and weather, the rooftop phase can take between one and three days.
2-3+ Days Total*

The Room

VELUX-trained pros will cut a hole in the ceiling to install the lower portion of the reflective tube between the roof and ceiling.

The Rooftop

VELUX-trained pros will cut a hole in the roof and install the top collar, the upper portion of the reflective tunnel, the lens and the flashing.
2 Hours*

The Room

There may be a small amount of interior drywall work depending on your replacement situation, but the majority of the replacement process will take place on the roof.

The Rooftop

VELUX-trained pros will get measurements from your existing skylights to ensure your replacements are a perfect fit, then they’ll replace your skylights

    M&M’s team leader Kenny was the first to arrive and reviewed the site and explained that the remaining 4 members with multiple vans would be showing up and what we could expect. He was extremely professional and polite and reassuring that M&M was indeed the best installation team in the US! We came up with a plan for parking and I showed him how our elevator could help get materials to the roof much faster. A two day install turned out to be a one day job and the results are amazing! You would never even had known the M&M had been there except for the fact that these 6 beautiful new white skylights had replaced the old 30 year old natural wood velux skylights. The blackout shades are amazing. The trim and caulking made it look like it was new construction! The roof looks the same - totally blended in! There wasn’t a hint of debris - they vacuumed up after themselves. Kenny explained the new controls and then returned the next morning with the Velux Active modules. M$M totally delivered on everything Kevin had promised! A 10 out of a 5 star reviews!

    We were so impressed with the installation crew from M&M Skylights. They removed our ancient skylight and expertly installed a beautiful new Velux modern replacement. The entire process was smooth, efficient, and clearly handled by experienced professionals. What really stood out was their attention to detail. When they finished, the work area was spotless—you wouldn't even know they had been there except for the gorgeous new skylight. Excellent workmanship and a fantastic result.

    The guys were pleasant, professional, and quick. We love our remote control skylight shades.
