Are square skylight domes interchangeable between different brands?
Not always. While square skylight domes may appear similar in size, the base dimensions, fixing points, and lip profiles can differ between brands and generations. Matching the fixing style and edge profile is just as important as matching the overall size.
Do square skylight domes sit flat on all roof types?
Square domes are designed to mount onto specific skylight bases and flashing systems. The roof material and flashing profile determine how the dome interfaces with the roof surface, so compatibility depends on the skylight system rather than the roof shape alone.
Can square skylight domes be upgraded to a different acrylic finish?
In many cases, yes. If the base and fixing profile match, a square dome can often be replaced with a different finish (such as clear or opal) without changing the rest of the skylight assembly. The key requirement is matching the physical dimensions and fixing method.
