Installing Skylights In Commercial Roofing: How, Why, And What

About Me
Keeping Your Roof In Decent Shape

After listening to a few friends of mine complain about the cost of replacing their roof, I realized that I should make sure that my own roof was in decent shape. I climbed up on a ladder to see if I could see the shingles, and things weren't looking very pretty. Some patches of shingles were missing entirely, while others looked badly damaged. Fortunately, I caught the damage early enough that experts could patch up the issues. However, since roofing damage isn't always obvious, I decided to put up this website so that others can spot trouble of their own.

Installing Skylights In Commercial Roofing: How, Why, And What

Have you recently walked into a big box store, looked up, and seen skylights? These commercial skylights are large rectangles from below, but resemble greenhouse roofs from above. How do they install these?  Why would they install these? Answers to these curious questions follow.

How Commercial Skylights Are Installed

Most commercial skylights are installed over bases. These bases are either concrete or fiberglass in nature, and they provide a lipped edge on which the edges of the skylights rest. The commercial roofing contractor then adheres and seals the skylights to the lipped edges of the bases, taking care not to leave a single gap for leaks to develop.

Why Stores and Other Commercial Sites Install Skylights

Skylights for commercial use have become very popular in the last decade for many reasons. 

These reasons include:

  • A demand for more natural light in architectural design
  • Natural lighting reduces the need for artificial indoor lighting and electrical expenses
  • Many skylights, such as the "extended pyramid" and "double pitch" designs, are decorative as well as functional
  • Commercial skylights can be installed vertically on the faces of buildings as well as on roofs, providing more versatility in their design
  • Skylights can reveal bad weather outside when everyone inside cannot see or hear it 

Of course, there may be other individual reasons for skylight installation, but these reasons are the more common ones.

What Styles and Kinds Are Used

There are dozens of styles of commercial skylights in use. There are domed clear squares, domed frosted squares, flat panels, circular, vaulted, canopy, clustered, pyramid, pitched and double pitched, lean-to's, octagonal, vertical glass walls, prismatic, tandem, and structural ridge, just to name a few. In addition to these styles, you can  also get hurricane graded varieties and various glazes for specific purposes. It all depends on what the commercial property owners want and what they are looking to do with the skylights.

The Installation Person

A roofing contractor installs the skylights in the roof. The construction contractor will install them on the front of the building. Skylights are typically installed on commercial buildings when they are being built, but they may also be installed years after the building has been standing. A lot of shopping malls in recent years have had remodeling work done that installed a lot of windows and a lot of skylights long after the malls had been built. You, as a consumer, will probably see a lot more of this trend in years to come.
