"A and GJ Construction did a great job replacing my home asphalt-shingle roof. The owner, Arian, is very knowledgeable, professional and friendly. My roof was completely replaced in 3 days for a very reasonable price. After the job was done, they left everything spotless clean. There was a leak due to a defective skylight from a previous installation, and Arian came back to take a look and fixed it at no extra cost. It turned out to be a defective glass seal, which Arian resealed using clear silicone. After the roof was replaced, it rained for two consecutive days and Arian called me each day to make sure there was no leak. Sometimes after we pay contractors, they do not even bother to follow up; and even to get in touch with them can be difficult after they get their money (but not Arian). Arian answered my call each time. He takes pride in his work which is rare nowadays. I already recommended him to do another roof repair job, which he successfully completed on time and as promised. I highly recommend A and GJ Construction for roofing replacement or repairs."

"Glenn is the best – and as a 70 year old, I have a lot of experience with workers in my home. I had a good deal of water damage over 2 floors and multiple walls and ceilings. It required expertise and a variety of skills to repair and replace all the various aspects, and to make it seamless with the undamaged areas. He is an absolute magician, totally outclassing any previous similar work that I’ve had done and resulting in a totally seamless, as-new appearance. And, he is a no-drama professional – reliable, honest, and sincere. His pricing was also more than competitive. He is now my go to guy for EVERYTHING related to the home."

Skylights FAQs, answered by experts

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.

Professionals repair or seal a skylight by inspecting for damages, resealing any gaps with appropriate weatherproofing materials, replacing cracked glass or seals, and ensuring the frame is tightly fitted to prevent future leaks and ensure proper drainage.

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.

Common skylight issues include leaks, condensation between glass panes, damaged seals, and cracks in the glazing. Regular exposure to weather elements can lead to these problems, requiring timely attention to preserve the integrity of the skylight and the surrounding roof structure.

Costs depend on skylight size, roof type, and additional features like blinds or tinting.
