Compare West Sussex roofing contractors on itemised scope, not headline price — a cheaper quote often uses concrete over clay, excludes lead work, or omits batten replacement. Check NFRC membership, public liability insurance, and local coastal experience. Get three written quotes so you can identify which one is the outlier. Call 01903 905 128.
West Sussex homeowners receive a significant number of roofing quotes over the life of a property. Some of those quotes are from excellent contractors. Some are not. This guide gives you a practical framework for separating the two — based on the specific characteristics of the West Sussex roofing market and the housing stock you are likely to be dealing with.
Why Comparing Roofing Contractors Is Harder Than It Looks
Comparing roofing quotes is not like comparing quotes for a commodity. Two contractors can give you quotes for "roof repairs" or "a new roof" that differ by 30–40% and both be quoting honestly — because they are quoting genuinely different things. The lower quote uses concrete tile; the higher uses clay. The lower quote uses sealant on lead flashings; the higher uses hand-dressed Code 4 lead. The lower quote excludes batten replacement; the higher includes it. Until you make the scope identical, you are not comparing like for like.
This is not always deliberate misdirection. Sometimes it reflects genuinely different views on what constitutes appropriate specification for your property. But it means you need to understand what is in each quote before you compare the prices.
NFRC membership requires an inspection of completed work before admission, minimum public liability insurance, and adherence to a formal complaints procedure — a baseline filter for West Sussex contractors.

Checking Credentials — the Non-Negotiables
NFRC Membership
The National Federation of Roofing Contractors is the primary trade body for professional roofing contractors in the UK. NFRC membership requires: work quality inspection before admission, minimum public liability insurance, a complaints procedure, and adherence to the NFRC code of practice. It is not a guarantee of quality but it is a meaningful filter. Check nfrc.co.uk — enter the contractor's postcode and their name should appear in the results if they are genuine members.
Public Liability Insurance
A minimum of £1m public liability insurance is essential. On a property job that could cause significant damage to your home or a neighbour's, £1m can be insufficient — we carry £5m. Ask to see the certificate, check the policyholder name matches the contractor, and check the expiry date. An insurance certificate that expired six months ago is worthless.
Local Track Record
Ask for references from jobs completed in West Sussex in the past 12 months, on properties of a similar age and type to yours. A contractor with extensive experience in Hampshire may have limited familiarity with the specific housing stock and material requirements of the West Sussex coastal zone. The Victorian terrace stock in Broadwater and Heene, the 1930s concrete tile estates of Goring-by-Sea and West Worthing, and the seafront flat roof requirements on Marine Parade all have specific characteristics that experience counts for.
What to Check in Each Quote
Materials Specified by Name
A proper quote names the specific tile profile and manufacturer, the lead code for all flashing work, the membrane type, and the batten treatment. "Quality materials" is not a specification. "Marley Eternit Mendip clay interlocking tile, Code 4 hand-dressed lead, Klober Permo-Air breathable membrane, 50×25mm pressure-treated batten" is a specification. If you cannot get this level of detail, the contractor has not finalised the specification — which means you have no reliable basis for what you are buying.
What Is Explicitly Excluded
Equally important: what does the quote explicitly exclude? Some contractors exclude batten replacement, assuming existing batten is sound. Some exclude disposal of existing tile. Some exclude scaffolding, quoting it as a separate item. Some exclude all lead work. These exclusions are not always unreasonable, but they need to be stated explicitly so you can compare the true total cost.
Guarantee Terms
A 10-year workmanship guarantee is the current industry standard for quality contractors. Check what the guarantee specifically covers — a guarantee that covers defects in workmanship is standard; one that also covers consequential damage is stronger. Check whether the guarantee is transferable on sale. Check what the process is for claiming under it.
Specific Considerations for West Sussex Coastal Properties
The West Sussex coastal environment creates roofing requirements that differ from inland work in ways that are relevant to contractor selection.
Coastal Material Specification
The correct specification for a coastal Worthing property uses stainless steel tile fixings (not galvanised), Code 4 hand-dressed lead as a minimum (not Code 3 or sealant alternatives), clay tile over concrete where replacement is involved, and GRP over felt for flat roofing. If a quote does not reflect these specifications, it is either a lower-quality specification or the contractor is not familiar with coastal West Sussex requirements.
Conservation Area and Listed Building Experience
If your property is in Tarring conservation area, on the Shoreham-by-Sea historic street pattern, or is a listed building, you need a contractor who understands the material requirements and planning obligations. Lime mortar on pre-1930 brickwork is not optional — standard cement damages the masonry. The ability to advise on planning prior approval for conservation area work is relevant before any work begins.

Frequently Asked Questions
NFRC (National Federation of Roofing Contractors) membership is the key credential. It requires inspection of work quality, minimum insurance requirements, and adherence to industry codes. Check nfrc.co.uk before appointing anyone. We are NFRC registered — call 01903 905 128.
Three is the standard. One quote gives you a price. Two gives you a comparison. Three gives you enough information to identify if any single quote is significantly out of line, and whether the outlier is the high one or the low one.
It depends on what is excluded. A quote that is significantly cheaper because it uses concrete tile instead of clay, excludes lead work, or does not include batten and felt replacement is not the same job as a more expensive quote that includes all of these. Always compare itemised scope before comparing price.
Public liability insurance of at least £1m — preferably £2m or £5m. Employers liability insurance if they have staff. Ask for the certificate and check the expiry date. Uninsured contractors leave you exposed if something goes wrong on your property. We carry £5m public liability — call 01903 905 128.
