GMG Roof Experts, the leading roofing company in London, offers top-tier roofing solutions tailored to your specific needs.
GMG Roof Experts carry out roof inspections and surveys across the whole London Borough of Hillingdon. We climb the roof, go into the loft, and give you a written condition report with photographs that tells you what is sound, what needs attention now, and what to plan for. Pre-purchase and homebuyer roof surveys, condition reports for landlords and managing agents, insurance and storm damage reports, flat roof and fibreglass surveys, and leak tracing, all from our Hayes UB3 base across Uxbridge, Hayes, Ruislip, Ickenham, Northwood and every postcode in between.
The background
Most roof problems are invisible from the pavement. Hillingdon's housing stock runs from Victorian and Edwardian slate terraces around Uxbridge and Yiewsley, through 1930s Metroland tiled semis in Ruislip, Eastcote and Northwood, to inter-war and post-war terraces in Hayes and Yeading and decades of extensions on top. On all of them the covering, the underlay, the flashings and the timbers age at different rates, and by the time a stain shows on a ceiling the water has usually been getting in for a while.
A proper roof inspection catches that early. On a house you are buying, it tells you whether the roof has years of life left or is a five-figure job waiting to land on you after completion. On a house you already own, it turns "the roof looks a bit tired" into a costed list of what to do now, what to do in a year or two, and what is fine to leave. For a landlord or managing agent it is the evidence behind a planned maintenance budget, and after a storm it is the report an insurer wants before settling a claim.
We are roofers, not desk surveyors. The person who inspects your roof is the person who could carry out the repair, so the report is grounded in what the work would actually involve, not a checklist ticked from the ground.
We are based in Hayes, we survey roofs across Hillingdon every week, and we report on everything from a single suspect valley to a whole roof at the end of its life.
What we survey
Every survey below is carried out in person by our own roofers, roof and loft, and every one ends with a written condition report and photographs. Any repairs we identify are quoted separately with no obligation.
An independent roof condition report before you buy, so you know what you are taking on and can use it in your negotiation or hand it to your solicitor.
A costed picture of your roof for homeowners, landlords and managing agents: what to do now, what to plan for, and what is fine to leave.
After wind or storm damage we document the condition, cause and extent with photographs in the format an insurer needs to assess a claim.
A focused check of felt, EPDM and GRP fibreglass flat roofs over extensions, garages, dormers and bays for ponding, splits, blisters and moisture ingress.
An inspection of the stack, the party wall junction and every piece of lead: flaunching, flashing, soakers, valleys and cover flashings where the roof meets brickwork.
Where water is coming in but the source is not obvious, we trace it from the stain back to the entry point across the covering, flashings, valleys and underlay.
A survey starts inside. We look in the loft first for daylight, damp, staining and the condition of the timbers, the underlay and the insulation, because that is where the evidence of a leak usually shows before anything is visible outside.
Then we get up to the roof itself, by ladder, tower, scaffold or foot access as the roof allows, and where a roof cannot be reached safely we use a pole camera or a drone. We work across the covering, the ridge and hips, the valleys, the flashings, the chimney, the verges and the rainwater goods, photographing anything that matters. You get a written report that sets out the condition, the defects, what needs doing and roughly when, with the photographs alongside.
How it works
The process is the same whether it is a pre-purchase survey or a leak investigation, and it starts with a conversation, not a sales pitch.
Call 07949 999411 or use the contact form. Tell us the property, why you need the survey, and any deadline you are working to.
We book a time, arrange the right access, and inspect the loft and the roof in full, photographing the covering, flashings, valleys, chimney and rainwater goods.
Within a couple of working days you get a written condition report with photographs: what is sound, what needs doing, and roughly when.
If you want any of the work done, we quote it separately. There is no obligation to use us, and the survey stands on its own.
The report
The report is written to be read by a homeowner, a landlord or a solicitor, not just another roofer. It sets out the roof type and covering, the condition of each element, the defects found with a photograph of each, a clear now, soon and later priority against every item, and an honest view on whether the roof is a case for ongoing repair or is reaching the point of a re-roof. Where a defect could not be seen safely, the report says so rather than glossing over it.
Slipped, cracked and missing units, surface loss, nail sickness and delamination, slope by slope.
The state of the felt, the battens and the rafters, plus insulation and ventilation seen from the loft.
Lead valleys, chimney and abutment flashing, soakers and box gutters, and where they have failed.
A straight view on whether targeted repairs will hold or the roof is a case for a full re-roof.
Flat roofs over extensions, garages, dormers and bay windows fail sooner than the main pitched roof, and they are the part buyers and owners most often ask us to check on their own. Old three-layer felt ponds and splits, GRP fibreglass crazes and cracks at the angles, and the upstand where the flat roof meets a wall lifts and lets water track behind it.
Our flat roof survey checks the falls and drainage, the seams and laps, the upstands and trims, the outlets, and the junction where the flat roof meets a pitched roof or a wall. The report tells you whether a localised repair will hold, whether the roof needs a full recover, and which covering would suit the deck.
A homebuyer report or a mortgage valuation looks at the whole house and often dismisses the roof in a line or two. The roof is usually the single most expensive thing that can go wrong after you move in, so it is worth having a roofer look at it properly before you commit.
We inspect the roof and the loft, photograph the condition, and give you a written report you can read before exchange. It tells you what state the roof is in, what will need doing and roughly when, and what a re-roof would involve if it is close to that point, so you can factor it into your offer or your budget.
Completed work
Every image below is a real GMG Roof Experts photograph taken from the company's own site. Each one appears once, and the caption names the type of work where it could be confirmed from the source.
Our roof surveys are carried out by working roofers from our Hayes base, inside the borough, not by someone who only ever sees roofs from the ground. That means the report is grounded in what a repair would actually involve, and the priorities are real ones.
We inspect the roof and the loft, photograph everything that matters, and write it up in plain language you can act on or pass to a solicitor. Any repairs we find are quoted separately, and there is no obligation to use us for the work. We are CITB certified, fully insured, and work from the right access for the roof.

Questions
The questions below come up most often from Hillingdon homeowners, buyers, landlords and businesses.
A loft inspection for damp, daylight and timber condition, and a full inspection of the roof itself: the tile, slate or flat roof covering and fixings, the underlay and battens, the ridge, hips, valleys and verges, the flashings, chimney weathering and leadwork, and the gutters and downpipes. Everything that matters is photographed, and you get a written condition report.
Yes. Every survey ends with a written condition report that sets out the roof type and covering, the condition of each element, the defects found with a photograph of each, and a now, soon and later priority against every item, plus an honest view on repair versus re-roof. It is written to be read by a homeowner, a landlord or a solicitor.
It is worth it. A homebuyer report or mortgage valuation usually dismisses the roof in a line or two, yet the roof is the single most expensive thing that can go wrong after you move in. An independent roof survey tells you the condition, the remaining life and the likely costs before you exchange, which you can use in your negotiation.
Yes. After wind or storm damage we document the condition, the cause and the extent with dated photographs in the format an insurer needs to assess a claim, and we can arrange a temporary make-safe at the same time if the roof is letting water in.
Yes. We survey felt, EPDM and GRP fibreglass flat roofs over extensions, garages, dormers and bays, checking falls and drainage, seams and laps, upstands and trims, outlets, and the junction where the flat roof meets a pitched roof or a wall, and we say whether a repair or a full recover is the right call.
It depends on the roof. Many surveys are done from a ladder, a tower or by foot access. Where a roof cannot be reached safely we use a pole camera or a drone to get the detail. If a survey does need a scaffold or tower for full access, we will tell you before booking.
The on-site inspection of a typical house roof takes around an hour to ninety minutes. The written report with photographs normally follows within two working days, and we can turn it around faster where a purchase deadline needs it.
Yes, if you want us to. Any repairs identified in the survey are quoted separately, so you can see the cost, but there is no obligation to use us for the work. The survey and its report stand on their own.
No. This is a roofing condition survey carried out by roofers, focused on the roof covering, the roof structure seen from the loft, the flashings, the chimney weathering and the rainwater goods. It is not a RICS Home Survey and it does not replace structural engineering advice where a structural problem is suspected. Where we see something that needs a structural engineer, the report says so.
