TL;DR: We think buying a garage roof should be one of the simplest jobs you organise this year, so we have taken the games out of it. You get one fixed price, in writing, before anything is booked — roof, fitting, removal of the old material and the disposal paperwork included. Nobody sits in your kitchen: most quotations are prepared from a copy of your original paperwork, or from the width and length of the building plus a few photographs sent by WhatsApp. If you hold a written quotation from a comparable specialist for comparable work, tell us and we will do our best to match it — just check that you are comparing the same specification. Asbestos-type material is removed by contractors trained in asbestos awareness Categories A and B and taken to a licensed disposal depot, with the correct paperwork handed to you. Most roofs are stripped and replaced in a single day.

What does “fixed price” actually mean?
It means one price, in writing, before anything is booked. Not a guide price, not a starting-from figure, and not a day rate that grows while somebody is standing on your roof.
A concrete sectional garage is a manufactured building. Its roof is a known area with a known number of sheets, a known ridge length and a known eaves length, which is why the job can be priced accurately before anybody arrives — provided the person quoting knows these buildings. That is the whole reason a fixed price is possible here when it is not always possible on, say, a house roof: there are no hidden layers and no surprises under the covering on a building type we see every week.
So there are no day-rate surprises and no extras invented halfway through the job. If we have quoted it, that is the price you pay.
From 35 years in the trade: the “extras” people get caught by are nearly always the same three — taking the old roof away, disposing of it legally, and capping and filling the ridge and eaves properly. All three are in our price. When you read any other quotation, those are the three lines to look for.
What is included in the price?
| Included in our fixed price | What it means on the day |
|---|---|
| The roof | The replacement covering itself, ordered to your building’s measurements |
| The fitting | Installation by time-served approved contractors |
| Removal of the old material | The old roof comes off and leaves site with the crew |
| Disposal paperwork | The correct documentation for what has been taken away |
| Ridge and eaves capping and filling | The edges finished properly rather than left open |
| Warranty | Five-year warranty on a system with a typical life of up to 40 years |
No prices are published on this page, because a garage roof price depends on the size of your building and the specification you choose. Send the width and length — or your original paperwork — and you will have a figure in writing.
Why there are no pushy salespeople
Nobody will be sitting in your kitchen bearing down on you. There is no commissioned sales visit, no “price that is only good tonight”, and no reason for either.
That matters beyond comfort. A contract agreed in your home is an off-premises contract in law, and the Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 give you a 14-day cancellation right on those and on distance contracts, along with a right to clear information before you commit. High-pressure doorstep selling exists precisely because it works against people who have not had time to think; quoting at a distance removes the pressure entirely and leaves you to compare quotations at your own pace. If you ever do feel pressured by any trader, Citizens Advice consumer helpline is the place to go.
How a remote quotation works
Most quotations are prepared from a copy of your original paperwork, or from the width and length of the building plus a few photographs.
- Find your paperwork if you have it. Original order paperwork, a handbook or an old invoice usually names the make and model and the exact size. That is the fastest route to an accurate price.
- If you have not, measure the building. Width and length, taken outside along the base, to the nearest few centimetres is plenty.
- Send photographs. One of each elevation from far enough back to see the whole building, one along the roof line from the ground, and one close-up of the eaves or ridge if you can get it safely from ground level.
- Tell us the access. Whether a vehicle can get near the garage, and whether anything overhangs it.
- We send the price in writing. One figure, with the specification alongside it, so you can compare it with anything else you hold.
Do not climb onto the roof to take photographs. If the covering is a corrugated cement type of an age that may contain asbestos, do not brush, drill, cut or pressure-wash it either — see our guide to spotting asbestos on UK garage roofs.
The Price Match Promise, and what to compare
If you have a written quotation from a comparable specialist for comparable work, tell us, and we will do our best to match it.
The two words doing the work there are written and comparable. A verbal figure cannot be matched because nobody can tell what it contains, and a cheaper quotation for a thinner, shorter-lived specification is not the same purchase. Do check what is actually being compared:
- whether the roof is box-profile steel with anti-drip lining and a plastisol finish;
- whether the ridge and eaves are properly capped and filled;
- whether the old material is taken away and disposed of legally;
- and whether there is a warranty at the end of it. Ours carries a five-year warranty on a system with a typical life of up to 40 years.
From 35 years in the trade: when a quotation is a long way below everyone else, the gap is almost never labour. It is usually the old roof staying on your drive, no anti-drip lining, or a lighter gauge sheet. Our article on the true cost of cheap garage roofs sets out where the money is taken out.
Comparing two quotations line by line
Use this as a checklist against any quotation you hold, including ours.
| What to check | Ask for it in writing | Why it changes the price |
|---|---|---|
| Sheet profile and gauge | “Box profile, what gauge?” | Lighter gauge costs less and flexes more — see the benefits of 0.7mm roofing |
| Anti-drip lining | “Is anti-drip lining included?” | Without it, condensation drips onto everything below |
| Finish | “Plastisol, and which colour?” | Finish quality drives how the roof looks and lasts |
| Fixing centres | “Fixed at close centres?” | Fewer fixings is cheaper and less rigid |
| Ridge and eaves | “Capped and filled?” | Open edges let wind and rain in from day one |
| Old roof | “Taken away, or left on site?” | Removal and disposal is a real cost someone pays |
| Disposal paperwork | “Will I receive documentation?” | Hazardous waste has legal paperwork attached to it |
| Warranty | “How long, and on what?” | A warranty on the sheet only is not a warranty on the job |
| Who fits it | “Employed, approved, or subcontracted on the day?” | Experience on this building type is the whole job |
| Price certainty | “Is this fixed, or subject to survey?” | “Subject to survey” is where extras appear |
If you are weighing up whether a new roof is even the right purchase, new roof vs new garage and how long a replacement garage roof lasts cover that decision, and garage roof replacement timing covers when to do it.
Responsible disposal is included, not extra
Asbestos-type material is handled by contractors trained in asbestos awareness Categories A and B and taken to a licensed disposal depot in line with Environment Agency and hazardous waste requirements. You receive the correct paperwork. We recycle what can be recycled.
That is not a courtesy, it is the law. Work with asbestos in Great Britain is governed by the Control of Asbestos Regulations 2012, with practical guidance in the HSE’s asbestos essentials task sheets. Asbestos waste is hazardous waste: it must go to a site permitted to take it, it travels under a consignment note, and anyone carrying it away as a business must be a registered waste carrier — a register you can search yourself on the Environment Agency public register.
Fly-tipped garage roofs are common, and the liability for waste does not simply vanish when somebody drives off with it. Keeping your consignment note is the proof that yours was dealt with properly. See understanding asbestos garage roof removal for how the removal itself works.
From 35 years in the trade: keep the disposal paperwork with your house papers. When you sell, the buyer’s solicitor asks about the garage roof, and a dated consignment note answers it in one line.
One visit, usually one day
Most roofs are stripped and replaced in a single day by time-served approved contractors. One visit, one crew, one price.
A single-day job matters more than it sounds: the building is never left open overnight, you are not taking two days off work, and there is no partly-finished roof waiting on a return visit when the weather turns. If your building also needs doors, fascias, gutters or a general tidy-up, those are far cheaper done while the crew and the access are already there — see garage revamps. If the building is genuinely finished, we also handle garage removal and supply new garages.
Who you are dealing with
We are family-owned and managed; our owner has 35 years’ experience of concrete garages, and we work nationwide from our Chesterfield yard. The yard is a working compound and is not open to the public — all quoting is done by phone, email and photograph.
Alongside roofing we remanufacture and stock obsolete spares for buildings nobody supports any more — locks, springs, cables, pulley wheels, clips, washers, eaves filler and gutter support kits are all in the spares shop. If you want to see the standard of finished work first, the gallery is the place to start, and why pay more for your concrete garage explains our thinking on specification.
To get a price: contact us, or send your building’s width and length with a few photographs.
FAQs
Is the price you quote really the price I pay?
Yes. You get one price, in writing, before anything is booked, covering the roof, the fitting, the removal of the old material and the disposal paperwork. There are no day-rate surprises and no extras invented halfway through the job.
Do you need to visit before you can quote?
Usually not. Most quotations are prepared from a copy of your original paperwork, or from the width and length of the building plus a few photographs sent by WhatsApp. That is also why there is no salesperson sitting in your kitchen.
How does the Price Match Promise work?
If you have a written quotation from a comparable specialist for comparable work, tell us and we will do our best to match it. It has to be written, and it has to be for genuinely comparable work — same sheet specification, same edge detail, old material removed and disposed of, and a warranty at the end of it.
What should I compare between garage roof quotations?
Whether the roof is box-profile steel with anti-drip lining and a plastisol finish, whether the ridge and eaves are properly capped and filled, whether the old material is taken away and disposed of legally, and whether there is a warranty. A quotation that is far cheaper is usually cheaper for one of those reasons.
Is removing and disposing of the old roof included?
Yes. Removal of the old material and the disposal paperwork are both inside the fixed price. Asbestos-type material is handled by contractors trained in asbestos awareness Categories A and B and taken to a licensed disposal depot in line with Environment Agency and hazardous waste requirements, and we recycle what can be recycled.
What paperwork do I get for asbestos-type waste?
You receive the correct documentation for the material taken away. Hazardous waste travels under a consignment note, and anyone removing it as a business must be a registered waste carrier — a register you can search on the Environment Agency public register. Keep your paperwork with your house papers for when you sell.
How long does a garage roof replacement take?
Most roofs are stripped and replaced in a single day by time-served approved contractors, so it is normally one visit rather than a return trip.
What warranty comes with the roof?
A five-year warranty, on a system with a typical life of up to 40 years.
Can I visit your yard?
No — the Chesterfield yard is a working compound and is not open to the public. All quoting is done by phone, email and photograph.
Do you do insurance work?
Yes, insurance work is undertaken. Call freephone 0800 318359 between 10 am and 4 pm, or contact us with the details.
