Roof + Solar.
Done properly.

If your roof is approaching the end of its life, renewing it and installing solar together can be the better long-term approach. Cube Solar coordinates the roof, solar and battery as one carefully managed project.

The question to ask first

Why put a long-life solar system on a roof that may soon need replacing?

Solar panels are designed to stay on a roof for decades. If the roof underneath is already near the end of its life, it will probably need attention while the panels are still working.

That means scaffolding up again, the panels lifted off and stored, the roof renewed, and the system refitted and recommissioned. It can be done, but it is cost and disruption you can often avoid.

If the roof is ageing, or a reroof is already on the cards, it is worth considering both together. Do it once. Do it properly.

How it works

One project.
One point of contact.

Instead of organising a roofer, a scaffolder, a solar installer and an electrician separately, and then working out who does what and in what order, you deal with Cube from the survey to the handover.

The value is not just convenience. It is that the roof, the solar layout, the cable routes and the battery are designed as one system, sequenced properly on site, and checked by the same people who designed them.

The roofing is carried out by experienced roofing specialists as part of the Cube project. The solar, battery and electrical work is done by our own electricians.

What we can coordinate
  • Roof works
  • Scaffolding
  • Solar PV
  • In-roof solar
  • Battery storage
  • Inverter
  • Electrical work
  • Monitoring
  • Certification
  • Handover

Not every project needs every item. We include what your roof and your home actually need.

Three routes

The right approach
depends on your roof.

01

Solar only

For roofs already in good condition and suitable for solar.

We survey the property and install the solar and battery system, with no roofing work that isn't needed.

Most of our installations take this route.
02

Roof renewal + solar

For homes where repairs, partial renewal or a full reroof make sense before solar goes on. Depending on the roof, the work may include:

  • Stripping the old covering
  • New membrane and battens
  • New tiles or reuse of sound ones
  • Flashings and leadwork
  • Scaffolding and waste removal
Only the work your roof actually needs. The solar then goes onto a renewed roof.
03

Integrated solar roof

The panels become part of the roof covering instead of sitting on rails above the tiles, finishing flush with the roofline.

We use proven in-roof systems such as GSE In-Roof, chosen to suit the roof.

Roof condition

We assess the roof
before designing the solar.

Roof condition is part of the first conversation and the survey. We look at the roof covering by drone and from the ground, and check the loft where we can. The aim is simple: to choose the right route before anything is designed.

01

Suitable

The roof appears suitable for solar without significant roofing work.

02

Remedial work recommended

Repairs or remedial work may be sensible before the solar goes on.

03

Roof renewal recommended

The roof may be better renewed before installing a long-life solar system.

This is a practical assessment to help choose the right installation route. It is not a structural survey or a formal roofing inspection. Where roofing work is recommended, our roofing specialists inspect the roof before the work is priced.

This is not about adding solar to a roof as quickly as possible.

It is about designing the roof, solar, battery and electrical system so the finished installation looks right, performs properly and is built for the long term.

Designed together from the start

Roof, panel layout, cable routes and equipment positions planned at the same time.

Sequenced as one project

One scaffold, one programme, and trades that follow each other in the right order.

Cleaner detailing

The option of in-roof solar, and flashings and penetrations designed in rather than added later.

Less chance of lifting panels later

A renewed roof under the panels means less likelihood of removing them for roof work.

One point of contact

One managed project and one main point of contact, so nothing falls between trades.

Quality checked by the designers

The people who designed the system check the finished installation and commission it.

Should I replace my roof before installing solar panels?

If the roof has many years of life left, no. If it is likely to need replacing within the life of the panels, it is usually better to deal with the roof first, or at the same time, rather than lift the panels off and refit them later. We look at the roof as part of the survey and tell you which route makes sense.

Can solar panels be installed while a roof is being replaced?

Yes, and it is often the best time. The scaffold is already up and the roof is open, so the solar can be planned into the roof rather than fitted on top of it afterwards. With in-roof systems, the panels go in as part of the new roof covering.

Is in-roof solar more expensive than standard panels?

The in-roof mounting usually costs a little more than a standard rail system. On a reroof the gap narrows, because the panels replace tiles you would otherwise buy. We price both options at survey so you can compare them properly.

Can Cube manage the roofing and solar together?

Yes. You get one survey, one quote and one point of contact. Cube manages the project from survey to handover. The roofing is carried out by experienced roofing specialists working as part of the Cube project, and the solar, battery and electrical work is done by our own team.

Can you install a battery at the same time?

Yes. The battery, inverter and any electrical upgrades are designed alongside the roof and solar, so cable routes, equipment positions and the consumer unit are planned once rather than worked around later.

Do I need integrated solar panels when reroofing?

No. Standard on-roof panels work perfectly well on a new roof. In-roof suits people who care about how the roof looks, or where planning or the street makes a lower profile sensible. We will show you both.

Can you reuse my existing roof tiles?

Sometimes. It depends on their condition, the tile type and how many are needed. Where tiles are sound and available in enough quantity, reuse can be sensible, particularly on period properties. We will say honestly whether it is practical.

Can you work with my existing roofer or architect?

Yes. If you already have a roofer or architect involved, we can work with them on the solar and electrical design and sequencing. Tell us at the start so the responsibilities are clear from day one.

Is the whole project VAT-free?

No. The solar panels and battery are currently zero-rated for VAT when installed in a home, until 31 March 2027, after which the rate is due to become 5%. Roofing work is standard-rated at 20%. Your quote shows each part separately, so it is clear what you are paying for.

Who handles Building Regulations for the roof?

We do. A full reroof normally needs Building Regulations approval, while smaller repairs often do not. Where approval is required, we arrange it, and the completion certificate is included in your handover pack.

Speak to us before the work starts.

The earlier we can look at the roof, solar layout and electrical requirements together, the easier it is to design the project properly.
