If your house needs a new roof, new windows, and new siding, it is tempting to start with whatever bothers you most. But exterior projects overlap. Done in the wrong order, one project can damage or undo another, and you may pay to remove and reinstall work you just finished.
Here is the sequence that usually makes sense, and why.
The general rule: top down, inside out
Water runs down, so exterior work usually goes from the top of the house down. And parts that sit inside an opening or under another layer, like windows, go in before the layers that wrap around them, like siding and trim.
1. Roof first
The roof protects everything below it. Roof replacement also involves tear-off debris, foot traffic, and work along the edges of the house. If you install new gutters or siding first, the roof crew has to work around them, and there is a real chance of damage.
The roof work also touches the drip edge and fascia line, which affects how gutters and soffit go on later. At West Coast Exteriors, every roof is a full tear-off with peel-and-stick underlayment, so the roof deck is exposed and checked during the job.
2. Fascia and soffit repairs
Once the roof is done, it is the right time to deal with rotted fascia boards and damaged soffit. Gutters hang from the fascia, so this has to come before gutters. Soffit and fascia come in several materials, including aluminum, vinyl, Hardie, PVC, and wood.
3. Windows and sliding doors
Windows and doors go in before siding when both are being replaced. Here is why:
- Windows are flashed and sealed into the wall opening. When siding is off, that flashing can be done cleanly and tied into the house wrap.
- If you replace siding first, new windows later may mean cutting into or removing new siding and trim around each opening.
If you are only replacing windows and keeping your siding, that is fine too. Window replacement can be done without new siding. The point is that if both are planned, windows come first.
4. Entry doors
Entry doors follow the same logic as windows. They sit in the wall opening and need to be flashed and sealed, so they go in before new siding and trim when both are planned.
5. Siding and trim
With the roof, fascia, windows, and doors done, siding wraps the walls and ties everything together. Trim around windows and doors goes on last in this step so it lines up with the new openings.
6. Gutters last
Gutters go on after the roof, fascia, and siding are finished. They hang on the fascia and their downspouts run down the walls, so installing them earlier means taking them down and putting them back up.
Can you do it in phases?
Yes. Many homeowners spread exterior work out. If you phase it, the same order still applies. Some practical tips:
- Fix active leaks first. If water is getting in, that comes before everything.
- Address safety and storm protection early, such as a failing roof or openings you worry about in storm season.
- Plan ahead even if you do one step at a time. Choose colors and materials with the whole house in mind so each phase fits the next.
Why one contractor can help
When different companies handle each step, coordinating the order falls on you, and each crew may not know what the next one needs. Working with one contractor across roof, windows, doors, siding, soffit, fascia, and gutters means one plan and one point of contact. That is the idea behind our full exterior renovation service.
Common mistakes to avoid
- New gutters before a roof replacement.
- New siding before planned window replacement.
- Choosing siding color without thinking about the roof and trim.
- Ignoring soft fascia before hanging gutters.
