Back in the day, glazed glass rooflights in a room could make the space it covers below very cold during the winter months. When these overhead features were sealed inadequately, the cold winds and draughts would pass through and create undesirable winter ventilation. Because of this, these structures were eventually made to be smaller. In extreme cases, the rooflights were removed and covered over because of their impracticality. For one thing, they were not weather-proof enough and maintenance was a huge and expensive problem.

But in recent times, there have been modern sealing and double glazing procedures that would make a better thermal efficiency in the room which could lessen the cost of heating. There has also been larger use of sturdy hardwood timber for the rooflights and modern paint for their bodies, making them more customizable and durable for the owner.

When paints were still low in quality, owners had to endure the constant weathering of their glass rooflights. Since these structures were constantly exposed to frost, rain and sunlight, the paints would get destroyed easily. People used to repaint often year after year, contributing to the larger maintenance costs. This problem has since been solved with the introduction of microporous paints and stains. Even rooflights in the harsh coastal and northern locations could withstand the constant natural battering.

With these new innovations, rooflights have been brought back into mainstream architecture. Modern roof lanterns, as they are called, are even more effective in providing a cozy environment below it.
