Finding the right roofing contractor can be daunting, but selecting a reliable professional is essential to ensure the quality and longevity of your roof.
When evaluating a roofing contractor, the objective is to establish competence, compliance, risk management, value - not simply price.
Key Factors to Consider:
-
Experience: Look for contractors with extensive experience in roofing and positive customer reviews.
-
Certifications: Ensure your contractor is certified and insured to carry out roofing work.
-
Quality of Materials: A trustworthy contractor should recommend high-quality materials like Birdcomb’s galvanised steel eaves filler combs.
-
Detailed Quotes: Get a clear, written estimate covering materials, labour, and timelines.
We've put together some questions below that are structured to help you assess a contractor rigorously and avoid common failure points in residential roofing projects.
1. Credentials, Legitimacy, and Compliance
You should establish that the contractor is operating legally and professionally.
- Are you a limited company or sole trader, and how long have you been trading?
- Can you provide your company registration number and registered address?
- Do you hold public liability insurance (minimum £2m recommended) and employers’ liability insurance if you use staff?
- Are you VAT registered, and will VAT be clearly itemised on the quote?
- Are you a member of any recognised trade bodies (e.g. NFRC, CompetentRoofer, TrustMark)?
Red flag: reluctance to provide insurance certificates or company details.
2. Experience and Specialisation
Roofing is not a single discipline - Professional experience must match your roof type.
- How many years’ experience do you have with my specific roof type (pitched, flat, slate, tiled, heritage, etc.)?
- Have you completed similar projects in the last 12–24 months?
- Can you provide local references or addresses of recent work?
- Who will be supervising the job on site day to day?
3. Scope of Work and Technical Approach
This is where many disputes originate. Clarity here is critical.
Can you provide a fully itemised written quotation?
Does the price include:
- Removal and disposal of existing materials?
- Replacement of felt/membranes, battens, and fixings if required?
- Leadwork (flashings, valleys, soakers)?
- Ridge system type (dry ridge vs mortar)?
- Fascia, soffits, and ventilation upgrades, Birdcomb?
- What products and brands will you be using, and why?
- Will you be installing ventilation to meet current Building Regulations?
- How will you protect the property from weather during the works?
Look for firms who will be using materials on your roof which will stand the test of time. Cheapest is often not the best.
Why Birdcomb?
Galvanised steel does not become brittle or degrade like plastic. Birdcomb is designed to last for decades, often matching the life of the roof itself.
Steel teeth cannot be chewed through or pulled out by birds, squirrels, or rodents, unlike plastic which can crack or be forced open.
Preventing pest entry helps avoid insulation damage, nesting debris, blocked ventilation, damp, and associated repair costs.
Plastic combs may need replacing multiple times over the life of a roof; Birdcomb is intended to be installed once and left in place.
Steel maintains its shape and strength in UV exposure, frost, and heat. Plastic can warp, crack, or snap over time.
Birdcomb is designed to allow airflow while blocking pests, so roof ventilation is not compromised when installed correctly.
Steel is fully recyclable and avoids repeated plastic waste over the years.
Although plastic is cheaper initially, the cost of replacement (labour, access, scaffolding) can outweigh the saving. Birdcomb reduces long-term ownership costs.
Provides a more robust and professional eaves detail, particularly on higher-value properties or full re-roof projects.
Distinguish clearly between workmanship guarantees and material warranties.
- What workmanship guarantee do you provide, and for how long?
- Are material warranties manufacturer-backed, and are they transferable?
- Will the guarantee still be valid if you cease trading?
- Is the work eligible for an insurance backed guarantee?
5. Building Regulations and Certification (UK-Specific)
Non-compliance can affect insurance and future property sales.
- Will the work require Building Control notification?
- Are you registered with a Competent Person Scheme?
- Will I receive a completion certificate on completion?
- Who is responsible for inspections and fees?
6. Project Management and Practicalities
You want predictability, cleanliness, and accountability.
- What is the start date and estimated duration?
- How many people will be on site each day?
- Will scaffolding be required, and is it included in the price?
- Who is responsible for waste removal and skips?
- How will you protect gardens, driveways, and neighbouring properties?
- What happens if bad weather causes delays?
7. Payment Structure and Contract Terms
Avoid large upfront payments without protection.
- What is the payment schedule?
- Is a deposit required, and how much?
- Are stage payments linked to defined milestones?
- Will I receive a written contract before work begins?
- How are variations or unforeseen issues priced and agreed?
8. Risk and Problem Scenarios
A competent contractor should answer these confidently.
- What happens if you uncover rotted timbers or structural issues?
- How are additional costs agreed?
- Who is liable for damage to my property or neighbouring properties?
- How do you handle post-completion defects or call-backs?
9. Price Comparison and Decision-Making
When comparing quotes, ask yourself:
- Are all contractors quoting on the same scope?
- Is one price significantly lower and if so, what's missing?
- Are cheaper materials or shortcuts being proposed?
- Lowest price is rarely lowest risk.

- Welcome detailed questions
