"Dealing with O'Brien Brother's Construction was a absolute pleasure from start to finish. The job consisted of removing and replacing a 30x30 vented skylight, new water & ice shield installed along with matching the existing shingles. The job came out great. I highly recommend this company for your next job."

"I recently had a skylight repaired and a small new roof installed, and I'm very satisfied with the work. The team was professional, punctual, and respectful of the property throughout the project. The skylight no longer leaks and looks great, and the new roof section blends in perfectly with the existing structure. They explained everything clearly before starting, provided a fair quote, and completed the job on time. Clean-up was thorough, and I appreciated their attention to detail. I’d definitely recommend them for both small roofing jobs and more specialized repairs like skylights"

Skylights questions, answered by experts

Leaks are the top concern for skylights, often due to improper installation or worn-out seals. Over time, water can seep in and cause major damage to your home’s ceilings and walls. Other common issues include condensation, which leads to mold, as well as physical damage from weather or debris. If they’re not sealed properly, skylights can also bring unwanted heat in the summer or cold in the winter, affecting your home’s energy efficiency and tacking on extra dollars to your bills.

Yes, you can install skylights on an existing roof, and it’s a common service that many homeowners opt for, especially on older homes built when skylights weren’t as prevalent. The installation process will be a bit more involved, and the design and planning process will take longer, meaning you’ll pay more to install a skylight on an existing roof than you would in new construction. The process involves cutting a hole in the roof, moving rafters, if necessary, and installing and sealing around the skylight.

Whether you need a permit to install a skylight depends on the scope of the project and local regulations. Generally, permits are required if the installation involves altering the structural components of your home, such as moving roof rafters. In some municipalities, a permit might also be necessary if the skylight protrudes above the highest point of your existing roof. However, if no structural changes are made, a permit may not be needed. The cost for a skylight installation permit is typically under $100. A convenient time to add a skylight is during a roof replacement, as your contractor can incorporate the new opening into the design.

Roof windows and skylights can be installed on various roof materials, but skylights are usually the only option that you have if you have a flat roof or a roof with a slope under 15 degrees. In these cases, roof windows have too high of a risk of leaking to be suitable options. The specific installation requirements may vary, so it's important to hire a window replacement contractor. Certain types of roofs may not be ideal if they limit the size of the window or if they pose an issue with rainwater collecting around the area.

Yes, skylights can affect a home’s energy efficiency, either positively or negatively. Properly installed, energy-efficient skylights with Low-E coatings, double glazing, and UV-blocking glass can help regulate indoor temperatures and reduce heating and cooling costs. However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.
