Harrow's mix of housing throws up all sorts of roofing jobs, from the interwar semis around Pinner and Hatch End with their original clay tiles, to the flat-roofed extensions common on properties near Wealdstone and South Harrow. A lot of the terraced stock in Harrow Weald still has timber sarking boards that need careful handling during a reroof, and the area's tree cover means gutters clog fast in autumn, particularly on tree-lined roads near Harrow-on-the-Hill. Local roofers deal with everything from slipped tiles after a windy week to full flat roof replacements using EPDM or GRP fibreglass, plus the usual chimney flashing and valley repairs that crop up on older bay-fronted houses.

The businesses listed here come from public business listings, ranked mainly by review rating and how many reviews they've built up, with a small boost for those showing a working website and phone number. We then check each business's homepage to confirm roofing is genuinely their main line of work, which stops general builders or handymen who happen to mention roofs from cluttering the page. Any listing flagged as permanently closed gets removed automatically as part of that process. Where you spot a Trust Verified badge, that business has gone through additional checks covering trade qualifications and accreditations, public liability insurance, trading history, customer review history and registered company information, and you can read more about what that involves on our How We Verify page. Businesses without that badge haven't been through our full verification, so it's worth doing your own checks before booking.

Before signing off any job, ask to see proof of public liability insurance and check whether the roofer holds any trade body accreditation, such as membership of the NFRC or a similar body. For anything involving scaffolding or working at height, ask who's supplying and erecting it, and whether that's included in the quote. Get at least two or three quotes for anything beyond a minor repair, since prices for full reroofs can vary by a few thousand pounds depending on materials and access. A written quote that specifies tile or slate type, guttering material and expected timescale will save arguments later, and it's reasonable to ask for photos of similar completed jobs nearby.
How We Select & Rate The Best Roofers in Harrow

Ranking is based on review rating and review count pulled from public business listings, with a modest lift for businesses that show a working website and phone number. We check each homepage to confirm roofing work is what the business primarily does, so unrelated trades don't appear on the page, and listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified have gone through 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 details. Other listed businesses haven't been independently verified by us, and being included isn't an endorsement. 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 →

Frequently Asked Questions

How much does a roofer cost in Harrow?
A small repair job, such as replacing a handful of slipped tiles or resealing a flashing, typically runs from around £150 to £400 depending on access and scaffolding needs. A new flat roof on a rear extension using EPDM rubber might cost £1,000 to £3,000 for a modest size, while a full pitched roof replacement on a semi-detached house in Harrow could run from £6,000 up to £12,000 or more depending on tile type and how much timber needs replacing underneath. Gutter clearing or replacement is usually a few hundred pounds. Prices vary a fair bit between roofers, so get two or three written quotes before deciding.
Do I need planning permission for roof work in Harrow?
Most like-for-like repairs and reroofs don't need planning permission, as they count as permitted development. However, if you're changing the roofline, adding a loft conversion with dormer windows, or your property is in a conservation area (parts of Harrow-on-the-Hill and Pinner fall under this), you may need consent from Harrow Council. It's worth checking with the council's planning department or asking your roofer whether they've dealt with similar properties in your area before work starts.
How long does a roof replacement take?
A straightforward pitched roof reroof on a typical semi in Harrow usually takes between five and ten working days, weather permitting. Flat roof replacements on extensions are often quicker, sometimes two to four days. Delays are common if there's hidden timber rot once old tiles come off, or if scaffolding hire runs into scheduling issues, so build in some flexibility when planning around the work.
What's the difference between a roof repair and a full reroof?
A repair addresses a specific problem, such as a leak, cracked tile or damaged flashing around a chimney, and is usually the cheaper, quicker option. A full reroof strips the roof back to the rafters, replaces the felt or breathable membrane, battens, and tiles or slates, and is worth considering if the roof covering is over 25 to 30 years old or if repairs are becoming frequent. A decent roofer should be able to tell you honestly whether a repair will hold or whether you're better off biting the bullet on a full replacement.
Should I use a local roofer or a national company?
Local roofers tend to know Harrow's housing stock well, including common issues with certain estates or terraces, and can usually get to you faster for emergency callouts like storm damage. National companies sometimes offer longer guarantees on materials, but response times can be slower and pricing less flexible. For most jobs, a well-reviewed local roofer with public liability insurance and a solid trading history is a sensible starting point.
How do I choose between roofers in Harrow?
Start by checking recent reviews, not just the overall star rating, to see how a roofer handles problems when they crop up. Ask for proof of public liability insurance and whether they hold accreditation with a trade body such as the NFRC. Request a written quote that breaks down materials, labour and scaffolding costs, and ask how long they've been trading under their current company name. Get at least two or three quotes for anything beyond a minor repair, and ask for photos or addresses of recent similar jobs in Harrow or nearby areas so you can see the standard of their work.
