Before you approve for a section of your home to cut for roof skylight installation, let’s look at some of pros and cons of roof skylights and having them installed.

Pros of Roof Skylights & Velux Windows

1. Natural Heating & Lighting

Roof skylights help rooms in homes and workspaces that have poor lighting. It lightens up dark spaces, especially those located in the middle of the building or without windows such as the bathrooms and stores. With a provision for natural lighting, it also cuts down on energy bills for electrical lighting. Installing roof skylights can also come in handy for spaces located in raining seasons or overcast climates.

2. Energy Cost Saving

As mentioned earlier, not only does a roof skylight provide heating, a vented skylight provides cross ventilation as a cooling effect. This effect of heating and cooling produced naturally can cut down on your energy costs quite significantly.

3. Healthy Ventilation

For most homeowners, fresh air within a space is not debatable. Skylight windows make for a refreshing space without the need for the air conditioners or heaters to be turned on all the time – a handy feel for the winter season.

4. Striking Home Beauty & Property Value

The attractive look of a naturally lighted room and the atmosphere it offers with a nice view outside has the potential to increase the value of the property. As such, installing skylight will often put your property at a favourable position to others of perceived competition.

5. Provides a Spacious Look

Small room spaces can significantly appear bigger when illuminated by skylights and the natural light they offer. Roof skylights give your room a look of extended space, a similar feature which homeowners achieve with mirrors placed at strategic locations to enhance the visual space. Moreover, roof skylights are quite useful because they brighten the room and offer a natural view with little to no obstruction.

6. Added Home Ambience

Given the seasonal changes in weather conditions, the ambience within your home is generally linked to weather and seasons. However, a skylight helps set/lighten the mood in your home all the time. Perceived moods could come as a warm, cosy, or even minimalistic feel at the home or workspace.

Having looked at some of the advantages of installing skylights, it is important to determine some of the factors that affect and heighten the risks of having a skylight installed in your home or workplace. Quite often, these factors are linked to poor to no consultations on skylight installations that would have otherwise provided a reliable decision-making process to homeowners.

Cons of Roof Skylights & Velux Windows

  • Settling for inferior quality materials that often come at cheap rates
  • Hiring skylight professionals with little to no experience for installations
  • Self-installation without professional supervision
  • Random placement of skylight with no professional consultation

1. Unmet Expectations

This is often common for the DIY-ers who are oblivious to the different types of skylights, what functions they offer and the features that best soothe the needs in their homes. Do you need more ventilation or need an automated skylight for periods of an unexpected rainstorm? What climate is typical to your home location? These considerations are relevant and help prevent the installation of skylights that fall short of expectation.

2. Possible Interior Exposure to Damage

With skylights getting more sophisticated, solutions to curbing damage to properties and cause of harm to occupants within the home or workspace have been provided. Excessive heating which could cause interior damage to carpets and furniture can be prevented by opting for tinted laminated and or tempered Skylight glass with UV or Low-E, which we often recommend. 

Also on the possible shattering of skylight glass (given an external force), a laminated glass film will hold the broken glasses in place to prevent more damage or casualty within the building. 

3. Uncontrolled heat (Sun glare) & Lighting

Placing skylights in shady areas or angles can let in too much light or provide much heat than needed. An installation on the south side of a building can provide solar heat in winter although it must be shaded in the summer for controlled temperature, north side installation in a building gives cooling light. These are relevant considerations that require professional consultations to be done right.

4. Poor Roof type & fit

Not all roof types are structural fits of any skylight of your choice. For example, a truss roof frame requires a lot more expertise than a standard roof frame which goes with almost all types of skylights.

5. Moisture (Roof) leaks

This is a common con for skylights made from poor and cheap quality materials that are prone to discolouration and wearing out within short periods. Quite often poor installation is also reasons for leaks, especially for skylights not mounted above the roof surface.

6. Conditional Expenses

These expenses are conditional because they depend on the type of skylight you want to be installed, and the brand. Of course, extra expenses in the form of maintenance and repairs come in based on the above cons, which are caused by overlooked professional services.
