First, we assess your current skylight and the surrounding roof structure. We check for water damage, measure everything precisely, and explain what needs to happen.Next, we order the right materials—usually Velux skylights because they’re built to last and come with real warranties. We schedule the work for good weather because skylight replacement means temporarily opening your roof.On installation day, we protect your interior space, remove the old skylight carefully, address any structural issues we find, and install your new skylight with proper flashing and weatherproofing. We clean up completely and test everything before we leave.The whole process typically takes one day for a standard replacement, weather permitting.
