""I am absolutely thrilled with my new cedar roof! From start to finish, the experience was top-notch. The craftsmanship is impeccable, and the attention to detail is evident in every shingle. The team was professional, courteous, and went above and beyond to ensure I was completely satisfied. Not only does my house look stunning, but I also have peace of mind knowing that my roof is durable and built to last. The natural beauty of the cedar has transformed the entire aesthetic of my home.

"Genti of Proper Construction was a pleasure to deal with. He explained how our project would be managed in full detail. He and his crew replaced our roof, along with new plywood, gutters, chimney, shutters, and skylight. Everything was completed with care and detail. We are very happy with the work and we highly recommend this company for any of your outside house projects. Thank you Genti!"

"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"

"They were able to replace the skylight in less than 2 weeks after the quote. They did a good job and make the finish on the inside look good. A few weeks later, there was a heavy rain and my new skylight is no longer leaking like my old one that was replaced."

Skylights FAQs, answered by experts

Skylights might sometimes increase your homeowners insurance premium, but the increase is usually minimal. Some home insurance companies won’t adjust your premium with the addition of a skylight, so you can contact your insurer or your professional skylight installer to ask about any expected changes. It’s crucial to have an expert install the skylight, as insurance companies may not insure your roof or cover water damage that results from a non-professional skylight installation.

When planning out skylights and deciding how big they should be, it's important to look at the dimensions of the interior space. In addition to changing a room aesthetically, skylights influence the illumination and temperature of the space below. The U.S. Department of Energy recommends that a skylight’s size should never be more than 5% of the floor area in rooms with many windows.

To maintain a skylight and ensure its performance over time, regular maintenance is required. This includes periodically cleaning the glass and frame to remove dirt, debris, and condensation. It is also crucial to inspect the seals and flashing at least once a year for any signs of wear, degradation, or leaks, paying special attention after heavy storms. Ensure that the drainage system is clear to prevent water buildup and potential leaks. Address minor issues like cracks promptly and consider occasional resealing to prevent drafts and moisture problems. While energy-efficient skylights with Low-E coatings or double glazing may require less upkeep, periodic professional servicing can help keep any skylight in optimal condition.

An improperly installed skylight could potentially impact your roof's warranty. This happens because roofing penetration is necessary during skylight installation. Check your warranty information to verify. In most cases, having skylights professionally installed with proof that flashing is being done to specifications can be enough to preserve your roof's warranty.

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.
