Skylight Installation Cost

The cost range of skylight repair is very wide, from replacing a faulty crank-handle to replacing an existing skylight completely with a new and maybe upgraded skylight.

You will find that the cost to replace a typical skylight depends upon the type, size, material, finish-quality, and accessories. The replacement cost further depends on the condition of the roof opening and structure, the type of roof and roofing, and the labor rate.

The typical skylight replacement cost range starts around $210 for a professional grade unit for DIY replacement. The cost rises to around $900 for a fully installed, deluxe-grade, fixed-closed unit. The cost can rise as high as $2,114 for a deluxe-grade, ventilating-opening unit with certain attractive accessories.

In the following tables the Labor Cost figures are what the able DIY person should expect to save by performing the complete installation. The Total High Cost allows for possible regional and seasonal variation of labor and material costs.
