Who this guide is for
- Owners planning facade, cladding or whole-exterior work.
- Anyone coordinating roof, windows and cladding together.
- Homeowners preparing to brief a builder or architect.
Facade and the roof relationship
The facade and roof meet at junctions that handle weather, so changing one often affects the other. Planning them together — rather than as separate projects — avoids mismatched details and repeated access costs.
Windows, doors, cladding and siding
Openings and cladding are usually part of the same exterior project. Coordinating them means consistent detailing, fewer trades returning twice, and a coherent final appearance.
Drainage
Exterior work is the moment to get roof and ground drainage right, because access is already in place. Ignoring drainage during a facade project is a common missed opportunity.
Access and scaffolding
Working at height needs safe access, which is a real cost and logistics item. Sharing scaffolding across roof, cladding and window work is far more efficient than mobilising it repeatedly.
Local rules and neighbour impact
Exterior changes are visible and can be subject to appearance, heritage or boundary rules; they also affect neighbours through noise, access and scaffolding. Confirm local requirements and communicate with neighbours early.
Sequencing
Exterior work has a logical order — weather protection and structure before finishes. Sequencing it well keeps the building protected throughout and avoids redoing completed work.
Exterior renovation planning checklist
- 1Plan facade and roof junctions together.
- 2Coordinate windows, doors and cladding in one project.
- 3Address drainage while access is in place.
- 4Plan safe access and share scaffolding across trades.
- 5Confirm local appearance, heritage or boundary rules.
- 6Communicate with neighbours about noise and access.
- 7Sequence weather protection and structure before finishes.
- 8Keep the building protected throughout the work.
- 9Use qualified professionals for all exterior trades.
Common mistakes to avoid
- Treating roof, cladding and windows as separate projects.
- Mobilising scaffolding more than once for related work.
- Skipping drainage while access is already available.
- Ignoring local appearance or heritage rules.
- Surprising neighbours with noise and access.
- Sequencing finishes before weather protection.
When to involve a professional
- Roofing, cladding, structural and weather-sealing work must be carried out by qualified professionals.
- Working at height requires safe, professional access arrangements.
- Local appearance, heritage and boundary requirements vary — confirm them.
- Costs and timelines vary by scope, access, weather and materials.

Frequently asked questions
Questions readers ask about this topic
Should I do exterior jobs together or separately?
Usually together. Roof, cladding, windows and drainage interact, and sharing access and scaffolding is far more efficient than mobilising it repeatedly for separate projects.
Do exterior changes need permission?
Often — appearance, heritage and boundary rules can apply, and they vary by location. Confirm with the relevant authority and consider neighbour impact early.
What order should exterior work happen in?
Weather protection and structure before finishes, so the building stays protected and completed work isn't redone. Your builder sequences it against your specific project.
