Solar Panel Roof Preparation Market Harborough
Solar panels last 25 years or more. The roof under them has to last just as long, or you pay to take the whole array off and put it back. That is why solar panel roof preparation in Market Harborough matters as much as the panels themselves. Tate & Sons Roofing are the roofers who get the tiles, felt and timber right first, so the solar crew fixes their brackets to a roof that will not let you down.
We are not solar installers, and we do not sell you panels. We check the roof, repair or re-cover what needs it, and handle in-roof mounting where you want a flush, tile-level finish. This page covers roof age and condition, tile and felt damage, on-roof versus in-roof, and taking panels off for later roof work. It sits alongside the wider service we run as a roofing contractor across Market Harborough. Start with a free drone survey and a written price before anyone books the scaffold.

Sort the Roof First, Then Let the Solar Crew On
A solar array adds weight and wind load to your roof. Every bracket needs a fixing into sound timber, and every lifted tile has to sit back down watertight. Fit panels over a worn roof and you lock in its faults for the next two decades.
Most solar firms are electricians first and roofers second. They know panels and inverters inside out. They are less likely to spot a brittle felt line or a cracked batten before the hooks go in. That gap is where leaks start, and it is the gap we close for homeowners across Market Harborough.
Our job runs before the panels arrive. We survey the roof, flag anything that needs work, and put it right. Then your chosen installer fixes to a roof we have already made sound. Two trades, one clear handover, no finger-pointing later if a tile slips.
Is Your Roof Ready for Solar? Age and Condition Come First
The first question is simple: how much life is left in the roof? If your covering has fewer than ten years left, panels are going on borrowed time. Take them off to re-roof later and you add a big bill on top of the roofing work.
A roof under fifteen years old, with no slipped tiles, no sagging and no damp in the loft, is usually a straight go. An older roof needs a closer look before you commit. Age alone does not rule it out, but worn felt and tired battens often do.
Here is what we check before we call a roof solar-ready:
- Tile or slate condition — cracks, slips and past patch repairs
- Felt underlay — brittle, torn or perished bitumen from before the 1990s
- Battens — split, rotten or under-nailed timber that a hook would loosen
- Rafters and structure — any sag, rot or bounce underfoot
- Flashings and valleys — old lead work near where the array will sit
- Loft signs — damp stains, daylight or dripping after rain
We see plenty of 1970s and 1980s roofs around Lubenham and Great Bowden with felt that crumbles the moment a boot lands on it. Better to know that before the hooks go in, not after the first storm. A free drone survey gives you the full picture from the ridge to the eaves.
Broken Tiles, Torn Felt and Cracked Battens — How Panels Go Wrong
Solar panels do not damage a roof on their own. Poor fitting does, and so does fitting to a roof that was never checked first. The classic fault is a broken tile right under a roof hook, hidden by the panel above it.
A hook has to slot around a tile without cracking it or holding the tile off its bed. Rush that, and the tile lifts a fraction and lets water track underneath. Multiply that by forty fixings and you have a roof that leaks in a dozen quiet places.
Felt is the other weak point. Older bitumen underlay tears from a dropped tool, a stray screw or a misstep. Once it splits under a panel, water gets past the tiles with nothing to stop it. You will not see the stain on the ceiling for a season or two.
We head all of this off at the prep stage. Cracked tiles get swapped, weak battens get renewed, and tired felt near the array gets sorted before a single bracket goes on. Get the groundwork right and the panels sit tight for their full life.
On-Roof, In-Roof or Re-Roof First — Pick the Right Route
There are three honest ways to get a roof ready for solar, and the right one depends on the roof you have. On-roof mounting bolts the panels above your existing tiles on brackets and rails. In-roof, or integrated, sets the panels into the roof in place of the tiles, for a flush finish. Re-roofing first renews the whole covering, then mounts the panels on a roof with a full lifespan ahead of it. In short: on-roof suits a sound roof, in-roof suits a new or good roof where looks matter, and a re-roof suits a covering that is near the end.
| :-: | :-: | :-: | :-: |
| Route | Typical cost (roof side) | Roof impact | Best for |
| On-roof mounting | Little to none on a sound roof; £150–£400 to swap any cracked tiles | Tiles lifted for hooks; a few may be cut or need replacing | Roofs under 15 years old with 10-plus years of life left |
| In-roof / integrated | Roughly £1,000+ more than on-roof for the tray, flashing kit and tile work | Tiles removed where the array sits; panels take their place | New builds, fresh re-roofs and looks-led jobs on good roofs |
| Re-roof, then mount | £4,000–£12,000+ for the new roof, then the mounting on top | Whole covering, felt and battens renewed; longest life | Worn roofs with under 10 years left, or perished felt and battens |
On-roof is the common choice, and rightly so on a roof with years left in it. In-roof looks tidy and reads as part of the roof, but it runs a touch warmer and costs more to fit. If your roof is on its way out, spending on either mount is money you may lose when the re-roof finally comes.
In-Roof Mounting and Re-Covering Done by Roofers, Not Solar Fitters
In-roof mounting is roofing work. The panels sit in a waterproof tray, and that tray has to flash into the surrounding tiles like any other roof feature. Get the detailing wrong and you have a large hole in the roof with panels sitting over it.
This is where a roofing crew earns its place. We strip the tiles where the array will go, fit the tray and its flashings, and dress the tiles back around it. The join between panel and tile ends up as watertight as the rest of the roof.
Re-covering works the same way. Where a roof needs renewing before solar, we strip it back, renew felt and battens, and re-lay the tiles. It ties in neatly with our Roof Replacement & Re-roofing service, so the roof and the solar prep get done in one visit and one scaffold. Homeowners in Foxton and Kibworth Beauchamp save on access costs by lining the two jobs up together.
Taking Panels Off and Putting Them Back for Roof Work
Sometimes the panels are already up when the roof needs attention. A slipped tile, a leak or a full re-roof still has to happen, and the array is in the way. We work with your installer to take the panels down, do the roofing, and get them refitted.
Panels come off in sections, get set aside safely, and the roof work goes ahead underneath. Once the tiles, felt or battens are sound again, the array goes back on the same mounts or new ones. It is fiddly, but it is routine when the two trades talk to each other.
Do the roof properly the first time and you avoid this whole job. That is the case for solar panel roof preparation up front. A sound roof under the array means no removal bill halfway through its life. Birds can also nest under a raised array and lift tiles, which is why some homeowners pair prep with Bird Proofing for Solar Panels at the same time.
What Solar Panel Roof Preparation Costs in Market Harborough
Prep cost depends on the roof, not the panels. A sound roof may need almost nothing beyond a check. A tired one may need tiles, felt, battens or a full re-cover before solar makes sense.
As a rough guide, here is what the roof side of a solar job tends to run in 2025 and 2026:
These are general market ranges, not a quote for your roof. Two roofs the same size can price very differently once age, felt condition and access are weighed up. The only way to a firm figure is a proper survey — which is exactly what our free drone survey gives you, followed by a clear written price with nothing added later. A fixed price needs a survey.
- **Swapping cracked or slipped tiles*— around £150–£400 for a handful, more on slate
- **Renewing worn felt and battens under the array*— priced by area, often a few hundred pounds up
- **Structural or timber repairs*— roughly £100–£200 per square metre of affected roof
- **Full re-roof before solar*— about £120–£275 per square metre, or £4,000–£12,000+ for a whole house
- **In-roof upgrade over on-roof*— roughly £1,000 more for the tray and flashing work
- **Removing and refitting an existing array*— around £1,000–£2,900, plus £300–£600 if new mounts are needed
Planning, Permissions and Getting It Signed Off
Most solar panels count as permitted development in England and need no planning application. Limits apply on how far panels stand off the roof, and listed buildings and conservation areas are the exception. Parts of Great Bowden and Medbourne sit in areas where visible roof changes get a closer look.
We check this before any work is booked, so nothing stalls once the scaffold is up. For the official rules on panel projections and where consent is needed, the Planning Portal guidance on solar panels is the place to read up first. In-roof arrays and re-roofs sit closer to the tile line, which often helps in sensitive spots.

Got Questions?
Your Solar Roof Preparation Questions, Answered Properly
Should I replace my roof before installing solar panels?
Only if the roof has fewer than ten years of life left. Panels last 25 years or more, so a roof that fails first means taking the whole array off to re-roof. That double job costs far more than doing the roof up front. A roof under fifteen years old and in sound shape usually needs no replacing at all. A survey tells you which camp your roof is in.
Will solar panels damage my roof tiles?
They should not, but poor fitting can. The usual fault is a tile cracked by a roof hook that was forced into place. Broken tiles hide under the panels and let water track past. We check and swap weak tiles before the brackets go on, so the array sits on sound covering. Done right, panels protect the tiles under them from the worst of the weather.
What is the difference between on-roof and in-roof solar panels?
On-roof panels sit above your existing tiles on brackets and rails. In-roof, or integrated, panels set into the roof in place of the tiles, for a flush finish. On-roof is cheaper, quicker and slightly cooler running, so it produces a touch more power. In-roof looks neater and reads as part of the roof, but it costs around a thousand pounds more to fit. In-roof suits new roofs and re-roofs best.
Can you install solar panels on an old roof?
Sometimes, but the felt and battens usually decide it. An old roof with sound timber, good felt and no slipped tiles can take panels fine. An old roof with perished bitumen felt is a different story, since a boot or a screw tears it easily. We survey the felt and battens first, then tell you straight whether it is ready or needs work. Age matters less than what the roof is made of underneath.
Do I need to strengthen my roof for solar panels?
Most sound roofs carry a domestic array with no trouble. Panels and rails add weight and wind load, so any sag, rot or bounce in the timbers has to be sorted first. Where rafters or battens are weak, strengthening runs roughly a hundred to two hundred pounds per square metre of affected roof. We check the structure as part of the survey, not after the panels are up. Getting it right first avoids a sagging array down the line.
How much does it cost to remove and refit solar panels for roof repairs?
Taking an array down and putting it back typically runs around a thousand to two thousand nine hundred pounds. Removal is the bigger part, with refitting and recommissioning on top. If the old mounts do not suit the new tiles, new racking adds roughly three to six hundred pounds. It is fiddly work, and it is why we push for sound roof prep before the panels ever go up. Do the roof first and you skip this bill entirely.
Do solar panels need planning permission?
Most do not, as they count as permitted development in England. There are limits on how far panels stand off the roof slope, and listed buildings and conservation areas need consent. Parts of Great Bowden and Medbourne fall under closer local rules on visible roof changes. We check this before work is booked, so nothing stalls once the scaffold is up. In-roof arrays sit closer to the tiles, which can help in sensitive spots.
Do you fit the solar panels as well?
No, we are roofers, not solar installers. We get the roof sound, handle in-roof mounting trays, and re-cover where needed. Your chosen solar firm fits the panels, the inverter and the wiring. We work alongside them, so the roof and the electrical work hand over cleanly. That split keeps each trade doing what it does best, with no leaks falling through the gap.
