Why It Matters
Let the Sunshine In With Our Window & Skylight Specialists
A dark, lifeless room can feel like a different house once the light comes in. A skylight transforms the space, and new windows cut your energy bills while making your home more comfortable. But both only work when they are installed correctly, and poor flashing is the number one cause of skylight leaks.
Because we are roofers first, we know exactly how to flash and seal a skylight so it never leaks. As certified Velux installers, we install and replace skylights and energy-efficient windows with the same attention to detail we bring to every roof, adding natural light, lower energy bills, and lasting value to your home.
