Skylight Repair & New Install Blog (Toronto)
This skylight has a lot of condensation forming on the underside of the interior pane of glass. Because it's in a bathroom, the high level of humidity in the air (from showering), causes an excessive amount of condensation to form, during cold weather. The colder the winter temperatures outside, and the higher the humidity level inside, the more condensation will form. IN Fact, the condensation was so much that it would occasionally drip down onto the drywall below and it has caused the paint to bubble.
This is an example of a skylight drainage system working properly. This Velux curb mounted glass skylight’s condensation drainage system is allowing any condensation that forms on the inside of the glass, to drain properly to the exterior. In cold weather, this continuous slow drainage of condensation, forms like an icicle.
Theres so much condensation on the inside of this skylight that you can clearly see if from outside. Eventually , all this condensation drips down into the gutters, drains down to the low end of the skylight, and is discharged to the outside.
This is something that we see quite often. The homeowner got his roofer to upgrade his vents at the same time as he was re-roofing the house. The roofer installed the large 14" turbine vent. Unfortunately, he put it on top of the old small hole (for the old passive vent that was there before), rather than cutting the hole to the size of the new vent. As you can imagine even though the new vent is much larger, it still doesn’tt draw much air as it has to draw through a small hole.
When installing new, more efficient venting systems, the hole in the plywood has to be cut to match the size of the new vent, for the new vent to be effective.
This is an example of the right kind of duct work to use for bathroom exhaust fan systems. The duct work is an insulated pipe with an aluminum exterior skin.
This allows for the hot air from the bathroom to go thru the pipe and to be exhausted to the exterior without putting any heat or humidity in the attic space…….that would cause a lot of mold. Notice that the piping is well sealed to the fan with tuck tape as well as sealed to the direct connect roof trap.
It’s also important to use the right roof exhaust trap (vent) on the exterior. Most common exhaust traps have a very low profile. We prefer to use the Ventilation Maximum trap that rises 8 inches above the roof. This keeps it out of the snow in the winter. Also, the Ventilation Maximum vents also has an anti-reverse damper that allows the hot moist air to be exhausted to the outside, without allowing cold winter winds to blow inside. So, a properly designed bathroom exhaust system gets rid of all the host moist air in the house directly to the outside, without allowing any hot, moist air into the attic.
VELUX is known for their design, engineering, quality and durability of skylight products and accessories. Here is an overview of their skylight products at a glance to help you make the right decision.
Solar Powered Venting Skylights
The Solar Powered Skylight (available for both deck and curb mount installations) features a solar panel that captures available daylight and uses it to recharge a highly efficient, fully concealed battery powered operator and control system. This operator is the power source that opens and closes the skylight, negating the need for electrical wiring during installation.
The Solar Powered Venting Skylight features a solar panel that captures any available daylight and uses it to recharge a highly efficient, fully concealed battery powered operator and control system. The battery powered operator is the power source that opens and closes the skylight. A rain sensor is built in to close the unit in the event that inclement weather arises while you're away.
There are several reasons a skylight might begin to leak. Most often, the cause of a leak is sealant that has failed or condensation build-up that occurs around the skylight, which often happens when there's an excess of melting snow or ice on the roof. If you have a skylight that begins to leak after a rain or wind storm, shingles around the structure may be clogged with dirt, dead leaves and other debris that prevent rain or melting snow from running off the roof as they should. Leaking can also occur when there are problems in other areas of the roof, and the leak eventually makes its way to the skylight.
Our experienced repair personnel will inspect your unit and your roof carefully to determine the source of the leak and ensure that no unnecessary repairs are made. Contrary to what you may think, skylight leak repair isn't always as costly and our crew will ensure that any repairs will be performed in way that least interfere with your home and its roof.
If you have an older skylight, leaking might be an indication that it's time to replace it. Another sign that you will need to replace your unit is if condensation and other moisture has leaked into the interior of the glass and stained it, causing some areas to have a milky appearance.
There are many considerations to be made when incorporating skylights into your home’s design. There are some as simple as where to locate the skylight to maximize the most natural light during the day, and some as complex as to which u-factor and solar heat gain coefficient ratings would be the most energy efficient in the climate you live. But have you ever considered the impact a VELUX skylight would have on your health and well-being?
The importance of daylight to many living organisms is paramount. Daylight is responsible for regulating many biological systems that allow us to function properly. It impacts our production of Vitamin D (which is important for calcium absorption), regulation of our circadian biological clocks, and even its impact on gene expression.
Now you may be wondering how much of an impact VELUX skylights can have on these biological functions. The answer is tremendous - most Canadians spend approximately 90% of their time indoors! Being indoors for such a lengthy period of time exposes our bodies to a higher concentration of pollutants; about 2 to 5 times more than if we were standing right outside of our home or office.

We were very pleased with Dave Flook from Skylights Unlimited; he has years of experience and specializes in sunrooms and solariums. Our sunroom was showing signs of structural weakness and we had numerous quotes and opinions. Dave proposed a practical and affordable solution that was just what we were looking for, preserving the warmth and elegance of the rest of the interior. It involved replacing the row of existing skylights, re-building the back wall and installing new energy efficient windows . Mike and Josh were pros - they were very skilled and had great work ethic working long days and even weekends. Dave was a stickler for detail and quality control which we were very impressed with. Loved the results and would definitely recommend! Roxanne
