Complete Guide to Rooflights

Rooflights, also known as skylights, are windows installed on a building’s roof to allow natural light to enter. They are usually made of glass or plastic and come in various shapes and sizes. Rooflights are frequently used in residential homes, commercial buildings, and other structures to provide additional lighting and improve a space’s ambiance. Rooflights, in addition to their aesthetic benefits, can help to reduce the need for artificial lighting and improve energy efficiency.

Types of Rooflights

Rooflights come in various styles, each with its advantages and disadvantages. Among the most common types of rooflights are:

  • Fixed rooflights are rooflights that do not open and provide a constant source of natural light. They are most commonly found in bathrooms, hallways, and other areas where ventilation is not an issue.
  • Rooflights with ventilation: These rooflights are designed to allow for air circulation and ventilation. They frequently include manual or motorized opening mechanisms, allowing you to control the amount of fresh air entering the building easily.
  • Walk-on rooflights: These are designed to support people’s weight and can be used as a skylight or to gain access to the roof. They are frequently made of tough materials like tempered glass.

How are Roof Lights Installed

The installation of rooflights can vary depending on the type of rooflight, the structure of the building, and local building codes and regulations. However, here is a general overview of the steps involved in installing a rooflight:

  • Preparing the roof: The roof must be designed before installing a rooflight by removing any existing roofing material and reinforcing the area where the rooflight will be installed. This could entail adding more framing or reinforcement to support the weight of the rooflight.
  • Cutting the roof opening: The roof light’s opening is cut according to the size and shape of the rooflight. This is done carefully to ensure a proper fit and minimize water leak risk.
  • Installing the rooflight frame: The rooflight frame is then attached to the roof structure, either by bolting it or by adhering it with a waterproof sealant. The frame must be securely attached to the roof to withstand wind and other weather conditions.
  • Attaching the glazing: After that, the glazing, or glass or plastic panel, is attached to the light roof frame. This may entail inserting it into a frame groove or using a sealant to keep it in place.
  • Installing flashing: Flashing is installed around the roof light to prevent water from leaking into the building. This may entail carefully sealing a waterproof membrane or metal flashing to the roof and rooflight frame.
  • Finishing the roof: After that, the roof is finished by installing shingles or other roofing material over the rooflight and flashing. This helps to conceal the rooflight and protect it from the elements.

It’s important to note that installing roof lights is best left to professional contractors with experience and the proper equipment to complete the job safely and effectively. Improper installation can lead to leaks and other problems, compromising the integrity of your roof and building.
