Skylights transform dark interiors into bright, open spaces — but only when installed correctly. At Sisu Roofing, we specialize in skylight installation and repair that integrates seamlessly with your existing roof system. Whether you’re upgrading an older unit or adding new natural light to your home, our team ensures watertight precision, durable flashing, and long-lasting beauty.
We install and service both residential and commercial skylights across the Flathead Valley, bringing daylight efficiency and modern design to homes, offices, and cabins alike.
A skylight can elevate any space — but poor installation or aging seals often lead to leaks and energy loss. Our experienced roofers handle every phase: from cutting and framing the opening to custom flashing, insulation, and finish work. We use high-quality skylight products designed for Montana’s climate — engineered to withstand snow load, prevent condensation, and resist UV degradation.
For skylight repairs, we diagnose issues like cracked lenses, failed seals, or leaking flashing. Most repairs can be completed without replacing the entire unit, saving you time and money.
If you notice any of these, it’s best to address them early — small skylight leaks can quickly damage insulation and drywall.
We provide skylight installation and repair across Northwest Montana, including:
Kalispell, Whitefish, Columbia Falls, Bigfork, Lakeside, Somers, Kila, and the greater Flathead Valley.

What types of skylights can you install?
We install fixed, vented, and tubular skylights from top manufacturers, available in both glass and acrylic options.
Do you repair leaking skylights?
Yes — most skylight leaks can be fixed by resealing flashing, replacing glass, or improving roof integration without full replacement.
How long does installation take?
Most installations are completed in a single day, depending on the roof type and interior finish work.
Can skylights be installed on metal roofs?
Absolutely. We use specialized flashing systems to integrate skylights into standing seam and corrugated metal roofing.
