Roofers in Glasgow — Roof Repairs, Conservatory Roofs & Roofline
If you are looking for roofers in Glasgow who turn up when they say, give you a fixed written price and stand behind the work for ten years, we are worth a call, with one honest caveat first. F J Allan & Sons is a family-run roofing firm based in the Falkirk and North Lanarkshire area, not in the city itself. We cover north and east Glasgow and the towns between us: Stepps, Bishopbriggs, Kirkintilloch, Lenzie, Moodiesburn, Chryston, Baillieston, Easterhouse and Springburn, reached along the M80 and M8 from Cumbernauld, Airdrie, Coatbridge and Kilsyth, where we work every week.
We are roofers first and conservatory roof specialists second, which matters in a city where many of the conservatory roof adverts come from window companies. Slate, tile, flat roofs in EPDM, GRP and felt, chimneys, leadwork, fascias, soffits and guttering, storm damage and water ingress are all our own work, done by our own team with more than 25 years’ experience behind it. Every job starts with a free, no-obligation survey and ends with a 10-year workmanship guarantee. Our reviews sit at 5.0 on Google and Facebook and 4.95 from 164 reviews on MyBuilder.
Roof leaking in Glasgow right now?
We offer fast call-outs across Glasgow for urgent leaks and storm damage — a temporary make-safe today and a permanent fix booked in.
Roof problems we fix
Whatever’s letting the water in, we’ve repaired it hundreds of times.
Slipped, cracked & broken tiles
We refit or replace slipped, cracked or missing tiles and slates and check the area for hidden damage.
Leaking lead flashing
Failed flashing around chimneys, dormers and roof junctions re-dressed with proper leadwork that lasts.
Cracked & loose ridge tiles
Ridge and hip tiles re-bedded and re-pointed where the mortar has cracked and washed out.
Flat roof leaks
Splits, failed joints and worn edges on felt, EPDM or GRP flat roofs patched or re-covered.
Blocked & failed valleys
Valleys cleared and re-lined so water runs to the gutter, not into the roof.
Chimney leaks & repairs
Cracked flaunching, spalled brick and failed pointing repaired, re-pointed and re-flashed.
Storm & wind damage
Lifted tiles and torn flashing made safe fast, then fully repaired — often insurance-friendly.
Leak tracing & damp
We find the true source of a leak rather than guessing, so it’s fixed once, not patched repeatedly.
Roofing costs in Glasgow — guide prices
Guide figures for typical jobs on the north and east side of Glasgow. Tenement work is the big variable: a repair that is a ladder job on a bungalow needs a tower or scaffold on a four-storey stair, and the bill is then shared between the owners under the rules above.

Guide prices only, drawn from 2025/26 UK cost guides and our own recent work across North Lanarkshire and the Forth Valley. Scaffold is itemised separately, and on a tenement the total is shared between the owners. You get a fixed written price after a free, no-obligation survey, and that is the price you pay.

Conservatory roof replacement in Glasgow
Most Glasgow conservatories went up between the mid-1990s and the late 2000s, and most still carry their original polycarbonate or plain glass roof. In a city that sees well over a metre of rain a year, that means a room too loud to sit in when it pours, too cold from October to April and too hot for the few weeks it is not raining. A warm tiled roof replaces the old panels with an insulated, plastered ceiling inside and lightweight tiles outside, so the conservatory finally behaves like a room. It can go on an old conservatory as long as the frames and base are sound, which our free survey checks before we quote.
Converting a glazed roof to a solid one needs a building warrant in Scotland. We prepare and submit the application to Glasgow City Council, East Dunbartonshire Council or North Lanarkshire Council depending on your address, and itemise the fee in your quote. Prices start from around £5,000, and because you are dealing with roofers rather than a window company, the junction between the new roof and your house wall is detailed like a roof, not an afterthought.
Roof repair in Glasgow
Roof repair in Glasgow follows the building. On a sandstone tenement it is usually a slipped or broken Scotch slate, a lead apron lifting at the chimney head or a blocked rhone pushing water back under the slates at the eaves. On the interwar cottage flats and the post-war schemes it is more often a cracked concrete tile, a verge that has lost its mortar or a ridge line letting in wind-driven rain. Either way, a brown stain on the ceiling is rarely directly under the fault, so we start on the roof and trace the water back to where it gets in rather than sealing the stain and hoping.
We do not charge a call-out fee, and we quote a fixed price after looking rather than an hourly rate. Small repairs start from around £150. If the roof needs making safe before a proper repair, we fit temporary cover and photograph everything so you have a record for your insurer or your factor. Call-outs run Monday to Saturday, 09:00 to 17:00.
Flat roof in Glasgow
Glasgow has more flat roofs than people expect. Tenements often finish in a flat platform between the pitched slopes, originally lead and later asphalt or felt, and it is the platform and its edge details that leak, not the slates. The 1960s left east Glasgow with flat-roofed houses, maisonettes and garage rows, and every decade since has added extensions and dormers with felt on top.
For a wet west-coast climate we favour EPDM rubber on larger, simpler roofs because it is one sheet with very few joints, and GRP fibreglass on small, detailed roofs such as dormers and bays where upstands and outlets need a rigid finish. Torch-on felt still earns its place on garages where budget matters. Where a flat roof covers a room we can upgrade to a warm deck at the same time, which cuts condensation as well as heat loss. A garage re-cover starts from around £1,200; tenement platforms are priced per square metre and shared among the owners.
Slate roof in Glasgow
A slate roof in Glasgow is nearly always Scottish slate, laid in diminishing courses on close sarking boards, and it is nearly always over a hundred years old. The slate itself is usually fine. What fails is the nails, which rust through and let slates slide one at a time, and the lead in the valleys, gutters and chimney flashings that has done a century of work. Nail sickness is why a tenement roof that behaved for decades suddenly seems to shed slates every winter.
We repair where repair is honest, re-slate one elevation where the rest of the roof has life left, and re-slate fully when the fixings have gone across the board. Matching slate comes from reclaimed Scotch stock where we can source it, or graded Welsh or Spanish slate where budget or supply decides. On a tenement the scaffold cost is shared with your neighbours, so the sums for a whole roof are often better than owners fear.
Tiled roof in Glasgow
Concrete tiles arrived on Glasgow roofs with the interwar bungalows and cottage flats of Stepps, Bishopbriggs, Riddrie and Carntyne, then covered the big post-war schemes. Many of those roofs are now 60 to 90 years old. The tiles go porous, grow moss in the damp air, and the mortar at ridges and verges washes out, so the first sign of trouble is often grit in the gutter and a damp patch at the top of a gable wall.
Isolated cracked tiles and a ridge re-bed are straightforward repairs from around £200. When the sarking is nailing through or the tiles crumble as you lift them, a full re-roof is the honest answer: strip, breathable membrane, new battens, new tiles and a dry ridge and verge system that needs no mortar. A three-bed semi in concrete interlocking tiles typically runs £4,500 to £9,000. On a four-in-a-block we help the owners agree the shared roof and price each side clearly.
Fascias and soffits in Glasgow
Fascias and soffits in Glasgow rot from the top down. A rhone that has overflowed for a few winters soaks the timber fascia behind it, the paint blisters, the gutter brackets lose their grip, and the soffit underneath starts to sag. On the 1930s to 1970s houses that make up most of the north and east suburbs, this is the most common roofline job we see.
We replace the timber with uPVC fascias and ventilated soffits rather than capping over rotten wood, because capping hides the problem and traps damp against the rafter feet. While the old boards are off we check the rafter ends and the bottom edge of the sarking and repair anything soft before the new roofline goes on. A full roofline of fascias, soffits and guttering on a semi starts from around £1,000, with a choice of white, black, anthracite and woodgrain finishes.
Guttering in Glasgow
Guttering in Glasgow has to move more water than almost anywhere else in Britain. On tenements and Victorian villas that means cast iron rhones, often shared along a whole terrace, where a single failed joint or a rusted bracket sends water down the stonework and shows up as damp high on an inside wall. On the estates it means uPVC that has sagged, pulled off its brackets or simply filled with moss from the roof above.
We clear, repair and replace. A gutter clean on a bungalow or semi starts from around £80, a leaking joint or loose bracket is usually a small fixed-price repair, and where the run has had its day we fit uPVC or seamless aluminium in deep-flow profiles that suit the rainfall here. On a tenement, rhone work needs safe access from a tower or scaffold and usually goes through the factor; we are used to both.
Chimney repairs in Glasgow
Glasgow tenement chimney heads are big, shared and high, with eight or twelve cans on a single sandstone stack serving flats up and down the stair. A century of frost and coal smoke leaves the pointing soft, the flaunching cracked and the cans loose, and the lead apron where the stack meets the slates is one of the most common leak points on the whole roof. Loose masonry at that height is also a safety issue the council takes seriously.
We repoint and re-flaunch, replace cracked cans, fit cowls or cap and vent redundant flues, and renew the lead at the base of the stack. On a house the work starts from around £300; on a tenement stack it is a common repair shared among the owners, and we itemise it so the factor can allocate the cost. Where a stack is beyond repair we can rebuild the head or, where every flue is disused and the council’s consent allows, take it down and slate over.
Glasgow's roofs: sandstone tenements, interwar bungalows and the schemes
Glasgow’s housing tells you what its roofs will do. The tenements of Dennistoun, Springburn and the inner north-east are blond sandstone if they went up before the 1890s and red sandstone, quarried in Dumfriesshire, if they came after. Above the stone the pattern is the same: Scotch slate on sarking boards, lead valleys, a flat platform at the top, shared cast iron rhones along front and back, and chimney heads serving several flats at once. Everything above the top-floor ceiling belongs to everyone, which is why factors exist and why the section on common repairs below matters.
Around and beyond the tenements sit the Victorian villas and terraces of Lenzie and Kirkintilloch, then the interwar cottage flats and bungalows of Riddrie, Carntyne and Stepps under concrete tiles, then the post-war schemes such as Easterhouse, where the same tiles were laid over thousands of roofs in a few years and are now reaching the end of their life together. A share of the 1950s and 1960s stock is system-built or no-fines concrete, some of it with flat roofs that have been re-covered several times.
Over all of it falls the weather. Glasgow takes well over a metre of rain in a typical year against roughly 700 mm in Edinburgh, and it arrives on a westerly wind. Rhones, valleys and outlets work harder here than almost anywhere in Scotland, moss grows on anything that stays damp, and a small fault at a gutter or flashing turns into damp and water ingress faster than owners expect.
Tenement common repairs in Glasgow: how the decision and the bill actually work
Most Glasgow flats sit under a roof that nobody owns alone. The Tenements (Scotland) Act 2004 fills in whatever your title deeds leave out with a default set of rules called the Tenement Management Scheme. Under it the roof, including the rafters and sarking that hold it up, is scheme property that every owner is responsible for. A repair is agreed by a scheme decision: one vote per flat and a simple majority carries it, taken at a meeting called with 48 hours’ notice or by going round the doors and recording who agrees. Once made, the decision binds the owners who voted against it and the ones who never replied.
Costs are shared equally between the flats unless the largest flat is more than one and a half times the floor area of the smallest, in which case each owner pays in proportion to floor area. If water is coming in now, any single owner can instruct emergency work to prevent damage or protect health and safety without waiting for a vote, and the cost is still shared; our note on what to do about an emergency roof leak covers the first hour. Most Glasgow stairs have a property factor, registered under the Property Factors (Scotland) Act 2011, who gathers the shares and instructs the roofer. Where an owner cannot be found or will not pay, section 50 of the Housing (Scotland) Act 2006 lets Glasgow City Council pay the missing share into the maintenance account and recover it from that owner, so a majority is not held to ransom by one flat.
Our part is to make the decision easy: a survey report with photographs the factor can circulate, a single itemised written quote that separates essential repair from optional upgrade, and a fixed price that does not move once the owners have voted. If your stair has no factor, we will work with whoever the owners nominate.
Working in Glasgow from North Lanarkshire, and how to choose a roofer
We will not pretend to be a Glasgow firm. Our base is in the Falkirk and North Lanarkshire area, about 25 miles from the city centre, and Cumbernauld, Airdrie, Coatbridge and Kilsyth are where our vans are most days. From there the M80 and M8 put Stepps, Moodiesburn, Chryston, Bishopbriggs, Kirkintilloch, Lenzie, Baillieston, Easterhouse and Springburn within easy reach, so that is the side of the city we cover; the full list is on our areas we cover page. If you are in the West End or on the Southside, a firm based there will serve you better and we will say so on the phone. Our hours are Monday to Saturday, 09:00 to 17:00, and within them we get to leaks quickly; we do not advertise round-the-clock cover because we do not offer it.
Whoever you choose, in Glasgow or anywhere, run these checks before you pay anything:
- Look the company up on Companies House and make sure the name on the quote matches the name on the record.
- Ask for the public liability insurance certificate and check the dates on it.
- Insist on a written quote that itemises materials, fixings, scaffold or access, waste disposal, any building warrant fee, VAT and payment terms.
- Never pay cash up front. A deposit against materials on a large job is normal; full payment before the work starts is not.
- Find reviews on platforms the firm does not control, not only on its own website.
- Get the guarantee in writing, with what it covers and for how long. Ours is 10 years on workmanship.
- On a tenement, ask how they will work with your factor and whether they will attend an owners’ meeting.
There is a fuller list in our guide to choosing a roofer and the questions to ask, our commitments are set out on why choose us, and you can judge the work for yourself in the gallery.
Roofing FAQs — Glasgow
How much should a roof repair cost in Glasgow?
A small repair such as refixing a few slipped slates or tiles on a house you can reach from a ladder starts from around £150 and rarely passes £500. Slate batches, lead flashings and ridge work sit between £200 and £900. On a tenement the same repair costs more because of access, but the cost is shared across the stair. We quote a fixed price after a free survey rather than an hourly rate, so the figure you see is the figure you pay.
Which parts of Glasgow do you actually cover?
North and east Glasgow and the towns between the city and our base: Stepps, Bishopbriggs, Kirkintilloch, Lenzie, Moodiesburn, Chryston, Baillieston, Easterhouse and Springburn, alongside Cumbernauld, Airdrie and Coatbridge, where we work every week. We are based in the Falkirk and North Lanarkshire area, about 25 miles out, and we do not have a Glasgow office. For the Southside or the West End, a firm based there will usually serve you better, and we will say so.
How is a tenement roof repair paid for in Glasgow?
Under the Tenements (Scotland) Act 2004 the roof is common scheme property. Owners take a majority decision, one vote per flat, and the cost is split equally unless the largest flat is more than one and a half times the size of the smallest, when it is split by floor area. A factor normally collects the shares. If an owner will not or cannot pay, Glasgow City Council can pay the missing share under the Housing (Scotland) Act 2006 and recover it from them later.
Are there grants for roof repairs or conservatory roofs in Scotland?
For most owner-occupiers, no. There is no national grant for roof repairs or for replacing a conservatory roof, and offers of a free roof are sales tactics rather than schemes. Councils have a duty to offer advice and can help with missing shares in tenements, Care and Repair services help older and disabled owners organise work, and some heritage schemes fund repairs in particular conservation areas for a limited time. If something applies to your address, we will tell you rather than sell round it.
What checks should I make before hiring a roofer in Glasgow?
Find the company on Companies House and check the trading name matches the quote. Ask to see the public liability insurance certificate. Get a written, itemised quote covering materials, access, disposal and VAT, with a fixed total. Do not pay cash up front. Read reviews on platforms the firm does not control, and get the guarantee in writing. A roofer who knocks on the door unannounced after a storm and wants to start today fails most of these tests.
Will my buildings insurance pay for storm damage to my Glasgow roof?
Usually yes, if the damage came from a single identifiable storm and the roof was in reasonable condition before it. Insurers exclude gradual wear, so slates lost through nail sickness or rhones that have leaked for years are not covered. Photograph the damage before anything is moved, note the date of the storm, and get a roofer's written report. In a tenement the block policy is normally claimed through the factor; if each flat insures separately, the owners claim their own shares.
