"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."

"Hired land star to fix a leak in my kitchen coming from ice buildup on my roof. Steve came the next day. New exactly what was wrong with roof and gave a fair price. Came the following day removing snow and ice. Then came the next day and fixed roof. He was prompt and is very knowledgeable. Would definitely recommend and use him again."

"Fast, excellent work, friendly people, reasonable price. I checked 2 other companies, and neither one actually went on the roof to check the skylight. Witz Glazz did, and explained what they found. No guesswork."

"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."

"I wanted to wait for a bad rain storm and wind to see if the job was done well, and I can say it was an excellent job. Overall, I was very happy with them. They came to fix our leaking skylights. The two offered the best price (beating three other quotes) and were able to quickly complete the job the next day. I really appreciate that they didn't give a quote and then said they need 3 weeks to show up. The replaced shingles and ice shield are holding up well, made it through the past several rain storms and really strong winds. They cleaned up and made sure no nails were around in the yard, that was great. If we decide to replace the whole main roof in the future, I would not hesitate to call them and get a new quote and let them do the job. Definitely call them and let them give you an estimate!!!!!!!"

Skylights FAQs, answered by experts

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.

Water will leak through a skylight if there are issues in the sealing of the skylight. Find and fix those issues yourself if possible, but it’s a good idea to contact a professional, as there could be much more water damage than you initially saw. Plus, it’s dangerous to work on a roof without the proper safety equipment and know-how.

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.

Prevent future skylight issues by conducting regular inspections, ensuring gutters are clean to prevent water pooling, applying protective sealants periodically, and trimming overhanging branches that might cause physical damage to 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.
