Framing Checked First
Rafter spacing and header framing confirmed before any decking is cut, not discovered mid-project.

Step-by-step new skylight installation: framing the opening, setting the curb, flashing, and finishing the interior light well.



A new skylight install follows a documented sequence, so the structure, flashing, and interior finish all work together.
01
We check rafter spacing and interior layout to plan the opening and framing before cutting begins.
02
The roof opening is cut to the curb dimensions with proper support framed in around it.
03
The curb is set square and flashed into the surrounding shingle courses, layer by layer.
04
The light well is framed, insulated, and drywalled, with a full site cleanup when the work is done.
Installing a new skylight where none existed means opening up a section of roof that was never designed to have a break in it. At SGM Home Restoration (NJ HIC #13VH13723900) we treat that opening as a structural and waterproofing decision, not just a hole for a piece of glass. That starts with confirming the rafter spacing can support the opening, and planning the header framing before any cutting begins.
We size the opening to the skylight curb, not the other way around, so the finished flashing has the clearance it needs to shed water instead of relying on sealant to make up the difference.
Here is what actually happens during a new skylight install, from the outside in:
The flashing details in that process are the same ones covered on our broader skylights page. If the roof around the new opening is older or already showing wear, it is worth reviewing our roof replacement page as well, since a new skylight is a natural project to pair with a full roof.
You get a documented process from the framing decision through the finished light well, not a generic install that treats the opening as an afterthought. Contact us today for a free estimate and a clear, written scope for your home.
Cutting a new opening into a working roof rewards planning before the saw comes out. Here is what that looks like on every job.
Rafter spacing and header framing confirmed before any decking is cut, not discovered mid-project.
Interior framing, insulation, and drywall finished cleanly, so the skylight reads as designed, not cut in.

We used SGM Home Restoration to replace our roof and we can’t recommend Silverio and his team enough. Very honest and reliable, they were on time, no surprises and they did a very profesional job. Totally recommended 👌
Have used SGM Home Restoration & Roofing on many occasions. They were my roofer on two apartment complexes in Flemington and also replaced my roof on my own home. Silverio is wonderful to work with. They are thorough in both their work and clean up. Also their prices were more than 50% lower than the highest bid I received for my home. Would highly recommend getting a bid from this company on your next home repair/improvement.
Silverio and his crew did an amazing Job with our roof. Totally recommended.
The best option. Professional services.
We had a great experience with Silverio from SGM Roofing. He installed a completely new roof on our home in Bridgewater, and we couldn’t be happier! Very punctual, very kind, and transparent from the beginning. He explained everything clearly, gave us a detailed estimate, and kept us updated throughout the whole installation. He finished everything the same day, just as he promised. He also did an amazing job cleaning up afterward. He even used magnets to make sure there were no nails left in our driveway! We are very happy with the work and would 100% recommend Silverio and SGM Home Restoration
