Need a different size or custom size/ shape/ configuration? Contact SIG Customer Service via the SIG Skylights Storefront link to discuss your application and / or to request a quote. Custom Skylights are our specialty! SIG Skylights are Beautiful, extremely Durable and a Smart investment! They are backed by a lifetime warranty on the frame. They are made with tempered, insulated glass that resists scratching and does not fade, haze, nor easily crack like plastic skylights, making them a perfect no-maintenance replacement for acrylic or fiberglass skylights. The opening in each sky light exactly matches the home’s finished opening– thus maximizing daylight into the home. The glass is specially tinted to conserve energy and reduce glare, heat gain, and UV damage. And, they are simple to install! IMPORTANT! The SIG Deck Mount (FM) Skylight will fit an inside finished opening equal to the quoted skylight size. E.g. if the skylight is an FMB 24x48 model, it will cover a 24” x 48” inside finished opening, which is already finished with sheetrock, etc., and sit directly on the roof deck around the finished opening. To INSTALL SIG FM style skylights, simply remove some shingles, cut a hole in the roof, adhere and fasten the skylight to the roof, applying self-sealing roofing membrane under and above the skylight flange, and replace the shingles. No need to purchase a separate flashing kit. Installation will require basic roofing tools including adhesive/ sealants and nails. A minimum roof pitch of 3:12 is recommended. Instructions are included in English and Spanish. For FULL SUN locations and where glare, UV damage and heat gain are a particular concern, Solar Reflective glass is recommended. (FMBSC style). All of our skylights are manufactured in the USA by a Veteran Owned Business, of quality materials sourced in the USA.

I bought this skylight assuming it will work for installation on a tile roof. The production description does not mention anything about its suitability for tile roofs or on how to install it on tile roof, while it does so for shingle roofs. I contacted Amazon and they are trying to convey this issue to the seller. The seller is dancing around the issue without trying to address it responsibly. At least, they can take it back and refund me for the same.

This was my first time ever doing any roof work, did some research and found this skylight. I found a video that shows how to install it.It’s perfect for a mobile home. I installed 2 ski lights a year a ago and they held up well so far in Wisconsin.Make sure to use water and ice shield, cover the bottom side of the opening first then the sides and last the top. Make sure that the bottom of the window is placed on top of the bottom row of shingles, see my pictures.Make sure to use a sealant around the edges.Make sure to watch videos on how to remove and reinstall shingles.I’m planning to buy a third one this summer to replace the bathroom skylight. I will call them and see if the run any discounts.

Replaced an old skylight when I recently re-roofed. I called SIG company at about 7:30 PM EST on a Friday night and one of the guys discussed my purchase with me for about 20 minutes. The skylight is well made and went on just fine. I might have considered the more tinted glass as the sunlight in the afternoon is somewhat intense in East Texas in the summer. The light concentration falls on a tile floor in the master bath so not a big issue. Would buy again based on overall good product and superior customer service.

My roof was damaged by hail and wind. The insurance company agreed to replace the roof. The roofing contractor suggested that I replace the original skylight. I tried getting a replacement from the local big box store, but they couldn't get it to me in time for the roofing contractor. Amazon delivered this skylight in two days and it fit perfectly. So far I am very pleased with the quality, fit and finish of the unit.
