How to Choose a Roofer in Sussex: Surveys, Quotes, Access and Red Flags

If you need a roofer in Sussex, compare what each roofer believes is wrong and exactly how they propose fixing it before you compare the price.

Two roofing quotes can be thousands of pounds apart because they are not actually pricing the same job.

One may be replacing a small failed detail. Another may be proposing a wider strip-and-recover. The total alone tells you very little.

Start with evidence of the problem

Before anyone quotes, gather what you can safely observe.

Useful information includes:

• where staining appears inside;
• when the leak happens;
• whether wind direction seems relevant;
• missing or slipped tiles visible from ground level;
• recent chimney, solar, gutter or loft work;
• whether the roof is pitched or flat;
• approximate roof age if known;
• photographs taken safely from ground level;
• loft photographs if the area is safely accessible.

Do not climb onto the roof to help diagnose it.

HSE describes roof work as high risk and says it must be properly planned with safe access and precautions.

Ask the roofer to explain the diagnosis

A good roofing quote starts with a reason.

Ask:

“What do you think is causing the problem, and what did you see that points to that?”

Possible causes can include:

• broken or slipped coverings;
• failed flashing;
• defective valleys;
• ridge or verge problems;
• chimney defects;
• membrane or underlay problems;
• roof penetrations;
• flat-roof detailing;
• guttering or drainage issues;
• condensation mistaken for a roof leak.

The goal is not to challenge every technical detail.

It is to understand why the proposed repair matches the symptom.

Compare the exact scope

A useful roofing quote explains:

• what area is being worked on;
• what is being removed;
• what will be retained;
• material type/specification;
• flashing details;
• battens/membranes where relevant;
• timber repairs included or excluded;
• waste removal;
• scaffolding/access;
• making good;
• start timing;
• duration estimate;
• weather contingency;
• payment stages;
• guarantee terms.

If the quote says “repair roof £2,500”, ask for more detail before accepting it.

Access is part of the job

Roofing cannot be separated from access.

Ask:

• Is scaffolding required?
• Is it included?
• Who arranges it?
• Does it cover the full work area?
• Will a tower, platform or other access system be used?
• Is access needed through a neighbour's land?
• Are there conservatories or extensions below the work area?

A cheap quote can become expensive if access was assumed but not included.

More importantly, you do not want a contractor improvising unsafe access because the quote ignored it.

Beware the instant full-roof diagnosis

Sometimes a roof genuinely needs major replacement.

But be cautious when a business jumps from a small symptom to a complete reroof without explaining the evidence.

Ask whether there are repair options.

Ask what happens if only the failed area is addressed.

Ask what condition the remaining roof is in.

A roofer may still recommend replacement. The difference is that you understand the reasoning.

For a substantial roof project, getting more than one opinion is usually sensible.

Landlords: ask for photographs before and after

Roof repairs often happen where the owner cannot easily inspect the finished work.

Before work:

• photograph the defect;
• record the roofer's diagnosis;
• save the written scope.

Afterwards, ask for photographs showing the repaired area, particularly where work is not visible from ground level.

That creates a maintenance record for future leaks, insurance discussions or property sales.

If the repair is temporary, label it as temporary in your records.

Building Regulations may apply

GOV.UK lists replacing roof coverings on pitched and flat roofs among work that can require Building Regulations approval.

The exact requirements depend on the project.

For a replacement or significant alteration, ask:

“Does this work need Building Regulations approval or notification, and who is responsible for it?”

Do not confuse planning permission with Building Regulations. They are separate systems.

Payment stages should match the project

For larger roof work, staged payments can be reasonable.

Ask what each payment corresponds to.

For example:

• deposit/material order;
• scaffold/access in place;
• defined work milestone;
• completion.

Be cautious about a large unexplained upfront payment.

If specialist materials are being ordered, it is reasonable for the business to explain what that deposit funds.

Repair guarantees: read the wording

A guarantee can sound reassuring without telling you much.

Ask:

• what work it covers;
• for how long;
• whether it covers labour and materials;
• what exclusions apply;
• who provides it;
• whether it is transferable;
• what happens if the business stops trading.

The answer may be perfectly reasonable.

Just do not treat the word “guarantee” as a substitute for the actual terms.

Flat roof or pitched roof?

If the problem is specifically a flat roof, you may want someone who regularly installs and repairs the system on your property.

TradeKind has a separate flat roof specialists section.

For general pitched roofing, chimneys, tiles, slates and broader roof repairs, start with roofers across Sussex.

Using TradeKind

You can browse Sussex roofer profiles and check whether the services and areas shown match your job.

Or post a roofing job with:

• town;
• roof type;
• symptoms;
• photographs;
• known age;
• urgency;
• safe access information.

If the issue is active water ingress, explain where the water is entering and whether electrics or ceilings are affected.

TradeKind gives you a simple route to relevant Sussex businesses, but it does not guarantee responses or the quality of workmanship. Use the profile to shortlist, then make the job-specific checks.

Final roofing checklist

Before choosing, confirm:

• the diagnosis makes sense;
• the scope is written;
• access/scaffolding is clear;
• materials are specified;
• hidden timber repairs are addressed in the quote terms;
• waste is covered;
• compliance responsibility is clear where relevant;
• payment stages are understandable;
• guarantee wording is available;
• the roofer has experience with this roof type.

If you can compare those points, you are comparing roofing proposals — not just prices.
