What this work involves
Consider the room from inside and coordinate the opening with structure, roof build-up, operation and shading.
- Position and daylight distribution
- Operation and shading
- Weatherproofing and internal lining
Use the following design considerations when coordinating this service with a wider project. Agree which parts apply to your request.
Resolve drainage, fixings and replaceability of exterior finishes together.
What the drawing needs to explain
Detail the lower edge and the junction with another material. Show where water can drain and how an element can be replaced without opening the entire finish.
Allow for later maintenance
Create a maintenance record for each material, including access points and product information. Base the first inspection on the chosen system and actual exposure.
Which trade-off matters?
Uniform colour and low maintenance are not automatically the same choice. Compare a coated surface with a material allowed to change visibly, including access for future maintenance.
Cost factors for this service
Costs depend on size, glazing type, structural alterations and finishes. Ask for the scope and selected specification to be described separately.
Bring this to the discussion
Photographs of the existing situation, available drawings and your requirements for roof windows, domes & rooflights. Identify the elements that should remain.
Questions about the work
What should I discuss before arranging roof windows, domes & rooflights?
A larger rooflight does not always give a better result. Consider overheating, privacy and how light is distributed in the room.
The design situations here illustrate choices; they are not completed projects or a diagnosis of your property.
