The practical order of work when you want clean energy and a sound roof without doubling the disruption.
The order of work matters
Solar panels are mounted to your roof, wired through your attic and connected to equipment on a wall. Every one of those surfaces is something a roofer may need to open, replace or repair. Doing the roof first — and doing it with the solar array in mind — avoids the most expensive mistake in this pairing: lifting an array to fix shingles underneath it.
If your roof is near the end of its service life, replace it now. If it has plenty of life left, have it inspected honestly before the design is finalised.
What the roof needs to know about the array
Panel layout is a structural conversation as much as an electrical one. Rafters, mounting points, snow or wind loads and the age of the sheathing all matter. We inspect the roof deck before committing to a layout, and we plan penetration points so they land on solid framing.
Shade is the other half of that conversation. A tree that will grow over the array in a few seasons can quietly undo a good design, so we look at the site over time, not just on the day of the survey.
Install the roof for the panels, and the panels for the next twenty years of the house.
Ventilation, insulation and heat
Attic ventilation and insulation decisions belong in the same meeting. Panels shade the roof, which changes how the deck behaves in summer, and improvements to insulation change how the house handles heat overall. Getting these right together makes the home more comfortable and the energy plan more effective.
Panels, battery and the everyday
Panel count is the easy number to focus on and the least useful on its own. What matters is what your household uses, when it uses it, and whether you want backup power during an outage. A modest array paired with a right-sized battery often serves a home better than a large array with nowhere to put the surplus.
We start with your routines and recent energy patterns, then size the system around them. Future additions — an electric vehicle, a heat pump, a home office — get planned for now so the equipment has room later.
Warranties, paperwork and the long view
A solar installation touches roofing warranties, electrical warranties and equipment warranties. They should be documented together, with clear notes about who to call for what. We keep all of it in one handover folder alongside the roof and window documentation, so nothing becomes a mystery in a few years' time.
