Pinner's housing stock throws up a fair range of roofing work, from the mock-Tudor semis around Pinner Village to the 1930s terraces near Hatch End and the bigger detached properties out towards Eastcote. A lot of these roofs are original clay tile or slate, now well past the age where flashing round chimneys and dormer windows starts failing, so repointing and re-roofing jobs come up often. Properties near Pinner Memorial Park and the older parts of the village also tend to have overhanging trees, which means blocked gutters and moss build-up are a recurring headache for homeowners. Anyone hunting for a roofer locally is usually dealing with one of two things: a leak that needs sorting fast, or a bigger job like a full re-roof that needs proper planning and scaffolding.
The businesses listed here are pulled from public business listings and ranked by their review rating and how many reviews they've got, with a small boost given to those showing a working website and phone number. We also check each business's homepage to confirm roofing is genuinely what they do day to day, which stops general builders or handymen who dabble in roofs from cluttering up the page. Listings flagged as permanently closed get removed automatically. Where you spot a Trust Verified badge, that business has gone through our full verification process, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. Our How We Verify page sets out exactly what that involves. For any business without that badge, those checks haven't been done by us, so it's worth doing them yourself before you hand over a deposit.
Before booking, ask to see proof of public liability insurance and find out whether the roofer holds any relevant trade accreditation, such as membership with a recognised roofing body. Get a written quote that breaks down materials and labour separately, and ask what happens if they find rotten timber or hidden damage once they're up there, since that's where costs can creep up. It's also worth asking how long the work will take and whether scaffolding is included in the price. Getting two or three quotes is standard practice for anything beyond a minor repair, and it gives you a much better sense of what's a fair price for the job rather than taking the first number you're given.
How We Select & Rate The Best Roofers in Pinner
Ranking is based on review rating and review count from public business listings, with a small lift given to businesses showing a working website and phone number. We check each business's homepage to confirm roofing work is what they primarily offer, which keeps unrelated trades off the page. Listings marked as permanently closed are removed automatically. Businesses displaying a Trust Verified badge have additionally passed our full verification, covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information. See our How We Verify page for the complete list. Other businesses shown haven't been independently verified by us, and being listed isn't an endorsement, so do your own checks before hiring.
Recommended and Featured listings are paid placements, so a business's fee affects whether and where it appears. Every other listing is ranked on rating and review count from third-party business listings. How we rank & verify →

A small repair job, like replacing a handful of slipped tiles or fixing a section of flashing, typically runs from around £150 to £400 depending on access and how much scaffolding or a tower is needed. A full re-roof on a typical Pinner semi can range from £5,000 to £12,000 or more depending on the roof size, the materials used and whether there's timber replacement needed underneath. Guttering work is usually cheaper, often £300 to £800 for a full replacement on an average terraced house. Prices vary a lot depending on the roofer's overheads and the complexity of the job, so getting two or three quotes before committing is a sensible move.
Do I need planning permission to re-roof my house in Pinner?
Most straightforward re-roofing work, like replacing tiles with the same or similar materials, falls under permitted development and doesn't need planning permission. It's a different story if you're in a conservation area, which covers parts of Pinner Village and areas near the High Street, or if you're changing the roofline, adding dormers, or the property is listed. Check with Harrow Council's planning department before work starts if you're unsure, and ask your roofer whether they've dealt with conservation area rules before.
How long does a roof replacement take?
A typical semi-detached roof in Pinner takes anywhere from three days to a week for a straightforward re-roof, weather permitting. Larger detached properties or roofs with multiple pitches, dormers or chimneys can take two weeks or longer. Rain delays are common in the UK, so it's worth building in some flexibility around the estimated finish date, and asking your roofer upfront how they handle bad weather days.
What's the difference between a repair and a full re-roof?
A repair deals with a specific problem, a cracked tile, a leaking valley, damaged flashing around a chimney, and is usually quick and relatively cheap. A full re-roof strips the roof back to the timber battens or rafters and replaces everything, which makes sense once a roof is getting patched repeatedly or is coming up to the end of its lifespan, typically 40 to 60 years for tiled roofs. A decent roofer should tell you honestly whether a repair will hold for a few more years or whether you're better off biting the bullet and doing the whole thing.
Will my roofer deal with scaffolding themselves?
Most established roofers either have their own scaffolding team or work regularly with a local scaffolding contractor, and this should be factored into your quote rather than added as a surprise extra later. Ask specifically whether scaffolding is included in the price you're given, how long it'll be up for, and whether there's an additional daily or weekly charge if the job overruns.
How do I choose between roofers in Pinner?
Start by checking recent reviews on public listings, not just the star rating but what people actually say about reliability and tidiness on site. Ask each roofer for proof of public liability insurance and whether they hold any relevant trade accreditation, and don't be afraid to ask for photos of similar jobs they've completed nearby. Get a written quote from at least two or three roofers, itemised so you can compare materials and labour properly, and ask about guarantees on both the workmanship and the materials used. If a business has a Trust Verified badge on this page, that means it's been through additional checks on qualifications, insurance and trading history, but for anyone without it, it's down to you to ask these questions directly before booking.
