Installing skylights can be a challenge especially on older structures when you have to cut into the existing substrate "roof deck" to ensure that they are situated properly. Sometimes utilities have to be relocated or the skylight adjusted to work around existing electrical, plumbing lines, or structural supports but in general, these systems are fairly easy to install. The most important part of the assembly is to make sure that the "skylight housing" is well sealed and that you provide for the proper thermal break to ensure that you are not losing energy through the skylight. Normally, we recommend that the curbs of these systems be constructed out of structurally insulated panels or wooden 2"x 12" if you are planning to use it in conjunction with an extensive greenroof. Most off the shelf pre-fabricated systems such as Velux come with a gasketed frames that will overlap the curbs and provide a weathertight seal. The flashing should be conducted per this attached detail or as approved by the manufacturer to ensure that it will meet warranty requirements. If you have any questions on the design for your skylight when used in conjunction with a greenroof assembly just let us know and we would be happy to assist you.
