St Helens has a real mix of housing, from the Victorian terraces around Thatto Heath and Sutton to the post-war semis in Eccleston and newer estates out towards Rainhill. That mix means roofing jobs vary a lot. A slate roof on an older terrace needs different skills and materials to a concrete tile re-roof on a 1970s semi, and flat-roofed extensions on many local homes need their own specialist attention, especially with felt or GRP fibreglass systems. Weather off the West Pennine Moors and the general Merseyside damp mean gutters, flashing and ridge tiles take a battering, so local knowledge of what fails first and why genuinely counts for something.
The roofers listed on this page are pulled from public business listings and ranked by review rating and review count, with a small lift given to those showing a working website and phone number. We read each business's homepage to confirm roofing is actually what they do day to day, which keeps general builders or other trades that only dabble in roofing off this list. Listings flagged as permanently closed are stripped out automatically. Where you see 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. You can check our How We Verify page for the complete list of what that involves. Businesses without that badge haven't been through our full checks, so it's down to you to confirm their credentials before signing anything.
Before booking a roofer, ask to see their public liability insurance certificate and, if the work involves gas flues or vents, check they're appropriately qualified for that part of the job. A written quote should break down materials, labour and scaffolding costs separately, and it's worth asking whether they're offering a guarantee on workmanship, not just materials. Getting two or three quotes for anything beyond a small repair is standard practice, not overkill, since prices for the same job can vary by a few hundred pounds between firms. If you're not sure what a fair price looks like, ask each roofer to explain what's driving their figure, whether that's scaffolding hire, tile type or the pitch and access difficulty of your roof.
How We Select & Rate The Best Roofers in St Helens
Rankings are built from public business listings, driven mainly by review rating and review count, with a small lift for businesses that show a working website and phone number. We check each business's homepage to confirm roofing work is genuinely what they primarily offer, and listings flagged as permanently closed are removed automatically. Businesses marked Trust Verified 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 full detail. Other businesses on this page have not been independently verified by us, and their inclusion 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, such as replacing a handful of slipped tiles or fixing a leak, might run from £120 to £350 depending on access and scaffolding needs. A full re-roof on a typical three-bed semi can range from £4,500 to £8,000 or more, depending on whether you're using slate, concrete tiles or a felt flat roof, plus how much timber work is needed underneath. Guttering replacement usually falls between £600 and £1,500 for a standard semi. Prices vary with material choice, roof pitch, and how easy the property is to access, so it's worth getting two or three quotes before deciding.
Do I need scaffolding for roof repairs in St Helens?
For anything above single-storey height or where the roofer needs to spend more than an hour or two up there, scaffolding is usually the safer and more practical option rather than ladders. Terraced houses on tighter streets, like those around Parr or Thatto Heath, sometimes need pavement licences for scaffolding, which the roofer should sort out, but ask upfront whether that cost is included in your quote.
How long does a roof replacement take?
A straightforward re-roof on a semi-detached house typically takes five to ten working days, weather permitting. Flat roof replacements on extensions are quicker, often two to three days. Bad weather can push timelines back, particularly with the amount of rain this part of Merseyside gets, so build in some flexibility rather than expecting a fixed finish date.
What's the difference between a flat roof and a pitched roof repair?
Flat roofs, common on extensions and garages across St Helens, usually use felt, GRP fibreglass or single-ply membrane, and repairs tend to focus on patching splits or resealing joints. Pitched roofs use tiles or slates over a timber structure, so repairs often involve replacing individual tiles, fixing flashing around chimneys, or sorting out sagging ridge lines. The materials and skills involved are different enough that it's worth asking a roofer which type of work they do most of.
Will my roof repair need building regulations approval?
Like-for-like repairs, such as replacing damaged tiles or patching a small area of felt, generally don't need building control sign-off. Larger works, like a full re-roof involving structural changes or a new flat roof over an extension, may need to meet current building regulations, particularly around insulation. A reputable roofer should be able to tell you whether your job needs a building control notice and can usually arrange this on your behalf.
How do I choose between different roofers in St Helens?
Start by reading recent reviews, not just the star rating, to see how a roofer handled problems or delays. Ask to see photos of similar completed jobs, ideally on properties like yours, whether that's a Victorian terrace or a newer estate build. Request proof of public liability insurance and check whether they offer a written guarantee on workmanship. Get at least two or three quotes for anything beyond a minor repair, and be wary of anyone quoting significantly below the others without a clear explanation why.
