I have spent the last several years surveying roofs and helping fit domestic solar systems across Liverpool, from older terraces near Wavertree to larger semis out toward Woolton. I started as the person carrying rails, ladders, and cable trays, then moved into roof checks and customer walk-throughs after I had seen enough awkward lofts and uneven slate to know what can slow a job down. I still like being on site because solar panels look simple from the pavement, while the real decisions usually happen in the roof space, at the consumer unit, and during the first proper conversation at the kitchen table.
The roof tells me more than the brochure
I always begin with the roof, because a neat quote means very little if the tiles are loose or the rafters are not ready for extra fixings. Liverpool has a lot of mixed roof stock, and I have seen two houses on the same street need completely different plans. One might have plain concrete tiles and easy loft access, while the next has brittle slate, a narrow hatch, and pipework running exactly where I would like to route cable.
A customer last spring had a back roof that looked ideal from the garden, with a clean south-facing pitch and very little shade. Once I got into the loft, I found a few old repairs around the chimney breast and some felt that had started to sag. I told him to sort the roof work first, even though I knew he was keen to get panels fitted before summer.
I would rather lose a week than trap a roof problem under a new array for the next 20 years. That is not dramatic. It is just practical. I have had enough calls from people who inherited poor installs to know that the cheapest job can become the most expensive one after the first winter storm.
How I size a system for Liverpool homes
I do not start by asking how many panels someone wants. I ask how they use power, whether anyone works from home, what time the washing machine usually runs, and whether an electric car is likely in the next few years. A family using most of its electricity in the evening may need a different setup from a retired couple who are home during the day and already run appliances while the sun is up.
On a typical three-bedroom house, I often see enough roof space for a system in the range of several panels rather than a huge array. The exact number depends on panel size, roof shape, chimney shade, and the inverter choice. I also point homeowners to the website if they want to compare local solar services before they book a survey.
The best conversations happen when the customer brings a recent electricity bill and has a fair idea of future plans. I had one couple in Childwall who were ready to fill every available bit of roof, but their daytime use was low and their budget was better spent leaving room for battery storage. We settled on a smaller array than they first imagined, and that decision made more sense for the way they actually lived.
I do not promise magic savings. Solar is still a long-term home improvement, not a scratch card. If a salesperson talks only about payback and never looks properly at the roof, the consumer unit, or shading, I would slow the whole process down.
Shading, weather, and the reality of Merseyside skies
People sometimes ask me if Liverpool gets enough sun for solar panels, and I understand why they ask. I have fitted panels in light drizzle, packed tools away under grey skies, and watched sea air roll in faster than expected. Even so, solar panels do not need perfect blue skies to work, and the bigger issue on many jobs is shade from chimneys, dormers, trees, or the house next door.
I carry a shade app and take roof measurements because guesses are not good enough. A small chimney shadow across one part of an array can reduce output more than a homeowner expects, especially during the lower sun months. On one Anfield terrace, a chimney stack looked harmless at noon, but the later afternoon shadow changed how I grouped the panels and where I placed the optimised sections.
Weather matters in another way too. I pay close attention to fixing points, wind exposure, and the condition of old mortar because a roof near the river can take a beating. A system that looks tidy on day one still has to sit there through years of rain, gusts, gull mess, and temperature swings.
I like simple designs when the roof allows them. Fewer awkward turns usually means fewer points of future trouble. That does not mean every roof needs the plainest layout, but it does mean I avoid clever-looking panel plans that make maintenance harder for very little gain.
What I check inside the house before I say yes
The roof gets the attention, yet the inside of the house can decide the job just as quickly. I look at the consumer unit, earthing, meter position, cable routes, and where the inverter can sit without annoying everyone. A garage wall is often ideal, but plenty of Liverpool homes do not have that easy option.
I once surveyed a terrace where the roof worked nicely, but the route from loft to meter cupboard was awkward because of a finished bedroom, a tight stairwell, and a recently decorated hallway. The customer had spent several thousand pounds on plastering and paint, so I took extra time to discuss visible trunking and alternative cable paths. That was a better conversation to have before the job, not halfway through with dust sheets already down.
Battery storage also needs a sensible spot. I do not like squeezing equipment into damp corners or places where access will be poor later. If I cannot stand comfortably in front of the kit for inspection and maintenance, I usually push for another location.
Fire access, ventilation, and basic tidiness matter more than people think. A neat install is easier to understand, easier to service, and easier to explain to the next electrician who opens the cupboard. I label things clearly because I have been that next tradesman, staring at a mystery box and wondering who thought silence was helpful.
The questions I wish more homeowners asked
I like it when a homeowner asks about scaffolding, warranties, bird protection, and what happens if a roof tile breaks during the work. Those are normal concerns, not difficult questions. A serious installer should be able to explain the plan without making the customer feel like they are slowing things down.
I also encourage people to ask who will actually be on the roof. Some firms sell the job and pass the work to teams the homeowner has never met. Subcontracting is not automatically bad, but I think the customer deserves to know who is responsible for the finish, the paperwork, and any return visit after commissioning.
Paperwork is dull until someone needs it. I keep copies of commissioning documents, handover packs, inverter details, and panel information because those records matter for insurance, house sales, and future repairs. A tidy folder can save a lot of phone calls years later.
My own rule is simple: if I would not fit it that way on my brother’s house, I do not recommend it to a paying customer. That rule has made me slower on some surveys, and I am fine with that. Solar panels are too visible, too long-lasting, and too tied into the fabric of the home for rushed decisions.
If I were advising a friend in Liverpool, I would tell them to start with the roof, then the bills, then the installer’s survey notes. I would tell them to be wary of anyone who gives a firm answer before checking the loft and the electrics. Most good solar jobs feel calm before they feel exciting, because the boring checks are what make the panels worth having years later.
