In House vs Subcontractors Roofers: What Edinburgh Homeowners Need to Know

In-house roofers are directly employed by the roofing company on your quotation, while subcontracted roofers are self-employed operatives brought in by that company to carry out the work on their behalf. The practical difference for Edinburgh homeowners comes down to one word: accountability. Under each model, responsibility for the work, the insurance, and the warranty sits with different parties.

For homeowners in Marchmont tenements, Georgian townhouses in the New Town, or Victorian terraces in Newington, understanding which model your roofer uses matters more than which sounds better in a sales pitch. Both models can deliver excellent work when set up properly. Edinburgh Borders Roofing operates with in-house teams as a matter of principle, but this article treats both models fairly so you can decide what fits your job.

Key Takeaways

• In-house roofers are directly employed by the company you hired.
• Subcontracted roofers are self-employed and brought in by that company for the job.
• Both models can produce excellent work; both carry distinct risks.
• Accountability, insurance chain, and supervision differ significantly between the two.
• Ask which model the roofer uses before agreeing anything in writing.
• The right question is not which is better in general, but which is right for your job.

What Is an In-House Roofing Team?

An in-house roofing team is one where the operatives working on your roof are directly employed by the company on your quotation, usually on PAYE terms with formal employment contracts. That means training, insurance, supervision, and workmanship all sit under a single business entity. The company hires them, trains them, insures them, and is directly responsible for what they do on your roof.

For a homeowner in Stockbridge or Bruntsfield, this arrangement means there is only ever one business to hold accountable. The roofer on the ladder and the company on your paperwork are the same operation. If a slate is fitted incorrectly, the same business that quoted the work must return and put it right.

What Is a Subcontracted Roofing Team?

A subcontracted roofing team is one where the company on your quotation hires self-employed roofers or a separate roofing firm to carry out the physical work on their behalf. The main contractor typically operates under a Construction Industry Scheme (CIS) arrangement or a similar self-employed structure. The company you signed with manages the project; a different party actually installs the roof.

Subcontracting is entirely legal and widely used across Scotland, from Livingston to Peebles. Many highly skilled roofers choose self-employment for genuine reasons of independence and flexibility. The subcontracted model is not inferior in principle. It simply changes where responsibility sits, and that has implications you need to understand as the homeowner.

In-House vs Subcontracted: The Core Differences at a Glance

The core differences between the two models show up across eight practical areas. This matters most on jobs like tenement re-roofing in EH10, listed building work in the Old Town, or full roof replacement on a Georgian townhouse, where accountability and quality control determine outcomes over decades.

What Is Checked	In-House Team	Subcontracted Team
Direct employment of workers	Yes	No
Single insurance policy covers work	Yes	Split
Company controls training and CPD	Yes	Varies
Direct supervision on site	Yes	Varies
Single point of contact	Yes	Varies
Warranty held by one party	Yes	Split
CDM Regulations 2015 responsibility chain	Simpler	More Complex
Quality control consistency	Higher	Varies

A “Varies” or “Split” entry does not mean poor. It means the outcome depends heavily on how the main contractor manages their subcontracted arrangement. Well-run subcontracted setups can match in-house standards. Poorly run ones cannot.

Accountability and Chain of Responsibility

Accountability is the single most important difference between the two models. With an in-house team, if something goes wrong on your Portobello flat roof, there is one company to call, one insurance policy that responds, and one party to hold to the guarantee. With subcontracting, responsibility can split between the main contractor and the operative who did the work. Sorting that out after the fact adds complexity for the homeowner.

CDM Regulations 2015 responsibility

The Construction (Design and Management) Regulations 2015 set out who is responsible for what on a construction site, including private domestic roofing work above certain thresholds. Under CDM 2015, the client (that is you), the principal contractor, and any subcontractors each hold defined duties. An in-house model keeps the principal contractor and the delivery team under one roof, which simplifies the chain. A subcontracted model spreads it across more parties.

Consumer Rights Act 2015 protections

The Consumer Rights Act 2015 gives you statutory rights against the trader you contracted with, which is the company named on your quotation. Those rights still apply if that company then subcontracts the work, but pursuing them can become slower and more complex when the trader must chase a subcontractor to remedy your issue.

Insurance Coverage Under Each Model

Insurance chain is where the subcontracting model most often trips homeowners up. Under an in-house team, one policy typically covers the entire job: public liability, Employer’s Liability under the Employers’ Liability (Compulsory Insurance) Act 1969, and Contract Works cover. Under a subcontracted arrangement, cover can be split between the main contractor’s policy and the subcontractor’s own policy, and gaps between the two can and do exist.

Ask specifically who is insured for what. A homeowner in Trinity or Corstorphine should ask whether the roofer physically on their roof is covered by the same policy as the company they signed the contract with. If the answer is “the subcontractor has their own”, ask to see both certificates.

Supervision and Quality Control on Site

Supervision under an in-house team is usually a working foreman or on-site supervisor employed by the same company. They are accountable to the same management, follow the same workmanship standards, and enforce the same quality checks across every job. Under a subcontracted model, supervision may be lighter, more remote, or handed to the subcontractor’s own lead operative.

Training and CPD

An in-house team can run consistent Continuing Professional Development (CPD), NFRC-aligned training, and standardised approaches to Working at Height Regulations 2005 compliance. A subcontractor brings their own training history, which may be excellent, mixed, or unclear. The homeowner cannot easily see the difference from the outside.

Snagging and finishing standards

Snagging (the process of finding and fixing small defects at the end of a job) benefits from a supervisor who works to a known standard. In-house teams typically inherit a snagging list from the company culture. Subcontracted teams may follow the main contractor’s snagging brief, or may follow their own, depending on how the arrangement is set up.

Communication: Single Point of Contact vs Multi-Party Coordination

Communication is a practical consideration that shows up daily during a job. With an in-house team, one office and one supervisor handle everything, from the initial free photographic survey to the final invoice. With a subcontracted team, you may deal with the main contractor for scheduling and paperwork, but the operatives on your roof answer to a different manager.

For a straightforward job in Colinton or Grange, this may not matter much. For a phased tenement re-roof in Marchmont with multiple owners and Scottish Building Standards paperwork to coordinate, communication complexity can become a real issue.

Warranty and Aftercare Continuity

Warranty and aftercare depend on continuity. An in-house team’s workmanship guarantee is honoured by the same company that installed the roof, and that company can send the same operatives back to inspect defects years later. Under subcontracting, the warranty typically sits with the main contractor, but the operative who actually did the work may have moved on. Pursuing a defect can become a paperwork exercise rather than a direct return visit.

Insurance-backed guarantees add another layer. NFRC members and TrustMark-registered contractors often participate in insurance-backed schemes that protect the homeowner even if the business ceases trading. These schemes typically pay out on the terms of the original contract, not on who did the work day to day.

Why Edinburgh Borders Roofing Runs In-House Teams

Edinburgh Borders Roofing has operated with directly employed in-house teams for over 30 years across Edinburgh, the Lothians, and the Scottish Borders. Every operative on your Newington slate roof or your Musselburgh flat roof is employed by the same business that signed your quotation. That means one insurance policy, one workmanship guarantee, one supervisor, and one company held to Scottish Building Standards. The team is IRATA-trained for rope access, NFRC-aligned in workmanship, and Citation Approved for health and safety compliance. Every job starts with a free photographic survey so that the scope, materials, and process are agreed in writing before work begins.

When Subcontracted Teams Work Well

Subcontracted teams work well when the main contractor runs a tight ship. A company that has used the same trusted subcontractors for years, maintains consistent training standards, holds full insurance across all parties, and provides direct on-site supervision can deliver work that is indistinguishable from an in-house team.

Some large national roofing companies operate this way successfully. Some regional contractors in Barnton or Cramond do the same. The model itself is not the issue. The management of the model is. A well-managed subcontracted arrangement can deliver excellent slate and tile roofing or flat roof installation. A poorly managed one produces the horror stories homeowners see on consumer complaint sites.

Signals of a well-run subcontracted setup

• Long-term relationships with the same subcontractors, not a rotating pool
• Written subcontracting agreements that pass workmanship standards through
• Main contractor’s supervisor physically on site regularly
• Clear insurance chain with certificates available for all parties
• Warranty honoured by the main contractor, not passed to the subcontractor

When In-House Teams Are the Better Fit for Edinburgh Properties

In-house teams are usually the better fit for complex Edinburgh jobs where accountability, continuity, and heritage sensitivity matter most. A tenement re-roof involving multiple owners in Tollcross, a listed building repair in the New Town, or specialist rope access work on a chimney stack in the Old Town all benefit from the tighter chain of responsibility that in-house delivery provides.

Tenement work

Tenement roofing under Scottish common ownership law involves shared responsibility across multiple flat owners, statutory notice procedures, and workmanship that must remain consistent across the whole roof. In-house teams tend to handle this coordination more smoothly because supervision, quality control, and communication all sit with one business.

Listed buildings and Conservation Areas

Roof work on Category A, B, or C listed buildings, and on properties in Edinburgh’s many Conservation Areas, requires heritage material matching, lime mortar knowledge, and awareness of Listed Building Consent processes. An in-house team with documented heritage experience is easier for a homeowner to verify than a subcontractor whose track record sits outside the main contractor’s paperwork.

How to Tell Which Model a Roofer Actually Uses

Some roofers describe their business in ambiguous terms. To find out which model actually applies to your job, ask three direct questions and listen carefully to the wording of the answers.

1. Are the operatives who will be on my roof directly employed by your company? A clear yes with no qualification means in-house. Anything vaguer than that usually indicates subcontracting.
2. Whose insurance covers the physical work? If it is a single policy in the main contractor’s name, you have an in-house model. If it is “we hold our insurance and the subcontractor holds theirs”, you have subcontracting.
3. Who holds the workmanship guarantee, and who returns to honour it? In-house teams honour their own guarantees. Subcontracted arrangements should still see the main contractor return, but the wording of the guarantee will make this clear.

If the roofer avoids direct answers to any of these, treat that as important information about how they operate.

Questions to Ask Before You Commit

Before signing anything on a job in Liberton, Musselburgh, Dalkeith, or anywhere else in the EH postcode range, cover these questions in writing:

• Do you use in-house teams, subcontractors, or a mix?
• Can I see insurance certificates for every party who will be on my roof?
• Who supervises the work day to day?
• Whose workmanship guarantee applies, and how is it honoured if the operative moves on?
• How do you handle snagging and post-completion inspections?
• Are there any parts of the job that will be subcontracted separately (scaffolding, waste removal, specialist lead work)?
• Who is my single point of contact throughout the project?

Getting written answers to these before work starts is far easier than negotiating them afterwards. A trustworthy roofer, whichever model they use, welcomes the questions.

Frequently Asked Questions

Q1. How do I know if a roofer uses in-house or subcontracted teams? 

Answer: Ask directly and get the answer in writing. A properly run roofing company will confirm their model without hesitation. Ask whether the operatives on your roof are employed by the company on your quotation, whose insurance covers the physical work, and who holds the workmanship guarantee. Vague answers to any of these usually indicate subcontracting.

Q2. Is it safer to hire in-house roofers in Edinburgh? 

Answer: Not automatically, but it is simpler to hold in-house teams accountable. Both models can be safe when properly managed under Working at Height Regulations 2005 and CDM Regulations 2015. In-house teams keep the responsibility chain shorter, which makes it easier to resolve issues if something goes wrong on your Edinburgh property.

Q3. Do subcontracted roofers carry their own insurance? 

Answer: Usually yes, but not always. Self-employed roofers typically hold their own public liability policy. However, cover levels and activities included can vary. If a subcontractor is on your roof, ask to see their certificate as well as the main contractor’s, and confirm that both cover roofing at height and match the scope of your job.

Q4. Who is responsible if a subcontracted roofer causes damage? 

Answer: The main contractor named on your contract holds primary responsibility to you under the Consumer Rights Act 2015. That contractor may then pursue the subcontractor separately. However, resolving the claim can be slower than under an in-house arrangement, especially if the two parties disagree over cause. Ask about the claims process before signing.

Q5. Can I refuse a subcontracted team on my roof? 

Answer: Yes, if this is agreed in writing before the contract starts. You can specify in your quotation acceptance that the work must be carried out by the main contractor’s own employees and not passed to a third party. Some contractors will agree to this; others will not. It is a legitimate question to raise during quotation review.

Q6. Are in-house teams better for Edinburgh tenement work? 

Answer: Often yes, because tenement work involves multiple owners, statutory notice procedures, and workmanship that must stay consistent across the whole roof. An in-house team simplifies coordination and quality control. Well-managed subcontracted teams can also do excellent tenement work, but the homeowner must verify the setup more carefully.

Q7. Does warranty change if the roofer uses subcontractors? 

Answer: The warranty stays with the party who signed your contract, which is the main contractor. In practice, however, honouring the warranty depends on that contractor’s ongoing relationship with the subcontractor who did the work. If the subcontractor moves on, the main contractor must arrange remedy through a different team. Ask how this process works before you commit.

Q8. Is it legal to use subcontractors on roofing jobs in Scotland? 

Answer: Yes. Subcontracting is a legitimate and legal business model widely used across Scotland’s construction industry. The main contractor must still comply with the Health and Safety at Work etc. Act 1974, CDM Regulations 2015, and Scottish Building Standards. What matters is that the arrangement is properly documented and that insurance and warranty chains are clear.

Conclusion

The core difference between in-house and subcontracted roofers in Edinburgh is not skill or reputation. It is accountability. In-house teams keep insurance, supervision, workmanship, and warranty under a single business. Subcontracted teams split those responsibilities across multiple parties, which can work brilliantly under strong management or become a problem under weak management. Both models are legitimate; both require different checks.
