Just like with skylight prices, location is a factor in determining the cost of a skylight installation job. Some places have more expensive labour costs, and this will add to the total cost of the project.

Another factor that significantly affects skylight installation costs is the number of skylights and how large are they.

How To Save On The Cost Of Skylight Installation

As usual, in any line of business, economies of scale and batching identical tasks reduces costs!

In case of skylights, you will probably want more than just one unit. So grouping them together will save you some serious cash!

If you place 3 or 4 of them in a row, you will only need to build 1 shaft, so a lot of labor and some materials will be saved.

However, since you are cutting larger holes in your roof rafters and ceiling joists, you will need to better reinforce the framing. This will also add to the labor cost and offset the savings a little bit.

As far as water-tightness goes, Velux and other manufacturers offer special flashing kits that allow you to stack multiple units together, without worrying about leaks.

How Much Does It Cost To Install A Tubular Skylight

Skylights: What You Need To Know

When properly installed, a light tube costs between $500 and $1,000, compared to more than $2,000 for a skylight. If you’re adept and comfortable working on a roof, you can install a light tube yourself using a kit that costs between $200 and $400. However, most people should hire a professional installer.

The price varies depending on the size of the hole to be covered, but generally speaking, a light tube is less expensive than a traditional skylight. It may not last as long nor provide as much illumination, but it can be an affordable option for your home.

A light tube consists of an aluminum tube with glass lenses attached to each end. One lens is placed inside the house while the other is left outside to allow light in. The tube is then mounted on the roof above the desired location. Finally, the outer shell of the tube is filled with water which serves as insulation against heat and cold, and also reduces noise from traffic below.

People often ask me how they can install a light tube themselves. While it’s not difficult, it is dangerous work that requires certain skills and tools not usually available to homeowners. I would only do it if I were sure there was no other option for keeping my customers warm during the winter months.

Light tubes are very efficient at letting in light because they use glass lenses instead of windows.

Skylights: Sometimes, they may appear to be nothing more than windows. However, theyre actually a very different building feature.

That said, only skilled professionals should install and maintain skylights. Thinking about getting skylights to add more light and space to your home? Make sure you know how they could impact your roof first:

Adding Edges to Your Roof: The Bad News

Skylights dont have to make your roof weaker especially if theyre properly installed. However, they can increase your chance of leaks and other related problems. When you install skylights, you add new edges to your roof. This requires new flashing, new sealants, and for new shapes to be cut through important roofing materials. All of this can add to the risk of something going wrong . If something like that does happen, your roof will require swift repairs.

Skylights can be made of glass, acrylic, or single glazed opal moulded units. The top glazing of the skylights can also be in clear or tinted glass, acrylic or polycarbonate. Skylights typically have long white-coloured or flexible light wells and a diffuser panel fitted at ceiling level.

Tubular skylights

Tubular skylights , capture direct-beam sunlight, transmit it down a highly reflective light well and diffuse it at ceiling level around the room. They can reduce absolute heat loss and heat gain compared with conventional skylights, because of their small cross-sectional area.

Tubular skylights work best in climates with a high incidence of clear, sunny days. On cloudy days, the amount of daylight admitted is considerably less than for a conventional, large area skylight.

In tubular skylights, a reflecting tube is used to direct sunlight downward. Using a straight tube with a silvered lining can achieve the best results. Flexible tubes can also be effective, provided their internal reflectance is high and the material is kept taut. Diffusers fitted to tubular skylights can reduce glare and throw the light over a broad area.

LED virtual skylights are an alternative in situations where a skylight is not easy or possible to install. They can simulate the effect of daylight by providing artificial light from LED lights, powered by solar energy.

Skylight Sizes & Prices

Labor prices are directly related to the size of the window. You may only need to pay $500 for cutting a 16″ x 16″ hole in the roof, but a 48″ x 48″ hole will range up to $4,000.

The right size depends on more than just cost. If you choose the wrong size, it could be too small and fail its function of bringing in natural light. For example, a 16″ x 16″ opening might not be enough to light a large, open-space living area. If it’s too large, air could escape, or water could leak in.

Details are essential for the installation. The opening in the roof and ceiling must be precisely aligned. If that doesn’t happen, the window will not fit into the spot. Fixing that mistake will require more time and money.
