The answer
Should an ageing roof be covered first?
A large roof is not automatically solar-ready. Its covering, remaining life, structural capacity, fire and access arrangements, lease rights and grid connection all affect whether an array can be installed and kept there economically.
01 / 02
Check the roof before the array
A roof close to replacement may need repairs or renewal first; removing and refitting panels later adds cost and disruption. Structural load, fixings, roof warranty and safe maintenance access require confirmation. Vents, skylights and fire or access routes can reduce the panel area far below a satellite estimate.

Match the roof to the business
A well-oriented array is more valuable when the site can use much of its daytime output. Review interval demand and planned electrification, then check inverter and network constraints. If the occupier is a tenant, establish who owns the roof rights, equipment and electricity benefit for the life of the project.
