Assessing a roof before buying PV. This guide is for Northern Ireland homeowners considering solar electricity or storage, and the details should be checked against their own property and current local arrangements.
Why this matters for Northern Ireland homeowners
Roof condition matters as much as available area. Loose tiles, ageing coverings, difficult access and structural concerns should be resolved before expensive electrical equipment is fitted.
What to check before making a decision
Identify pitches facing different directions, roof windows, chimneys and shaded sections. Record whether a planned extension or roof replacement could change the installation.
Questions to put to an installer or provider
Arrange a professional site survey and ask for written findings. An online roof estimate is useful for screening, but cannot verify structure, wiring routes or safe access.
Practical checklist
- Keep a copy of your electricity usage and recent bills.
- Ask for a written explanation of equipment, exclusions and assumptions.
- Confirm relevant Northern Ireland requirements before paying a deposit.
- Compare at least two detailed options where practical.
- Retain your quotation, warranties and handover records.
