Extension roof opening or skylight

For an extension roof with a roof opening (dormer) and/or skylight, or one that was added later, special attention must be paid to the beam structure. To install larger skylights or skylights, load-bearing beams, which are part of the roof structure, must be regularly interrupted. If this is not properly supported, there is a real risk of the roof surface sagging. The adjustments must be carried out professionally and properly .

If the adjustments are not carried out professionally and properly , improvements/modifications to the structure will be necessary. Be aware that the roof surface may sag or weaken further if the structure is not repaired (in time). However, this repair is usually relatively simple; it can be remedied by inserting a few beams between the existing purlins.

Often, due to finishing, it's not visible whether the beam structure around the roof opening has been modified. In that case, there are no visible deviations that would indicate that any modification would be improper.

The lead connections around the roof opening (of the extension) should be checked automatically.

• Check lead connections around roof openings annually. Any blown-up lead can be repaired immediately.
• Remove dirt and leaves around the roof opening to prevent obstructions in the drainage system.

If, after inspection, the lead connections around the roof openings (of the extension) show minor defects, they are (in most cases) easy to repair. For repairs, consider using permanent waterproofing tape. This type of tape is available at any hardware store. For larger defects, consult a professional. An expert in this field may be able to install new lead, extending the lifespan of the skylights.

If the hinges and locks of the roof opening (dome or skylight under construction) or any mechanical components are not functioning properly, they should be checked (by a professional) and replaced if necessary. After that, the whole thing will usually function properly again.

If the skylight (dome or skylight under construction) is difficult to open and close, we recommend first spraying all moving parts with penetrating oil and then lubricating them. If necessary, the entire system can be adjusted so that the operation, as well as the window's opening and closing, functions smoothly and as intended.

With an acrylic skylight, if it becomes damaged or broken, there's a risk of water ingress. In that case, repair is usually no longer possible. The dome (only the cover) must then be replaced.
