A roof guarantee should tell you exactly what’s covered (workmanship, materials, or both), for how long, and whether it survives if the contractor stops trading. In Edinburgh, tenement roofs add a further wrinkle: because most tenement roofs are shared property, the guarantee also needs to state clearly whose flat, or whose share of the roof, it actually applies to.
If you’re comparing quotes for roof repair or replacement in Edinburgh, understanding this now saves a lot of confusion later, especially if something goes wrong two or three years down the line.
The Three Types of Roof Cover, and Why They’re Not the Same Thing
Most homeowners assume “guarantee” means one blanket promise. In practice it’s usually three separate layers, each protecting against a different risk.
Workmanship guarantee: This is the roofer’s own promise, covering faults caused by how the job was done: poor flashing details, bad felt laps, incorrectly bedded ridge tiles, or leadwork that wasn’t dressed properly. It’s only as strong as the company standing behind it. Typical terms run anywhere from 2 to 10+ years depending on the scope of work.
Manufacturer warranty: This covers the roofing product itself, not the labour. Slates, tiles, membranes, and flat roofing systems each carry their own manufacturer terms, commonly 10 to 20 years, and some require the contractor to register the installation with the manufacturer or the warranty is void before it even starts.
Insurance-backed guarantee (IBG): An IBG can protect the contractor’s written workmanship guarantee if the contractor ceases trading. The insurer may fund or arrange covered remedial work, subject to the policy terms. Cover periods, excesses, exclusions and eligibility vary, so ask for the full policy wording and schedule before work begins.
The mistake most homeowners make is assuming one of these covers everything. It doesn’t. A manufacturer warranty won’t pay for a leak caused by bad installation, and a workmanship guarantee won’t cover a slate that fails because of a manufacturing defect. Ask your roofer which of the three you’re actually getting, in writing, before work starts.
What a Roof Guarantee Usually Doesn’t Cover
Guarantees are not insurance policies, and they don’t cover every problem a roof might develop. Common exclusions include:
- Storm and impact damage
- General wear and tear over time
- Lack of maintenance, such as blocked gutters left unattended
- Work carried out by a different, unrelated contractor after the original job
- Areas outside the specific section that was repaired
That last point matters more than people expect. If a handful of slates were replaced around a leak, the guarantee typically applies to that repaired area only, not the condition of the surrounding roof covering, the old sarking felt underneath, or the chimney stack next to it. A reputable roofer should say this upfront rather than let you assume the whole roof is now covered.
Why Edinburgh’s Tenement Roofs Complicate This
Here’s where Edinburgh differs from a lot of generic UK roofing advice. A large share of the city’s roofing stock consists of tenement blocks in areas such as the New Town, Old Town, Marchmont, Bruntsfield, Leith, and Stockbridge.
In many Edinburgh tenements, the roof is treated as “scheme property” for maintenance purposes. The title deeds should be checked first. Where they do not fully regulate the repair, the Tenement Management Scheme provides default rules for decision-making and cost allocation. Repairs can generally be approved by a majority of owners, but each owner’s financial share is determined by the titles or the applicable scheme rather than being automatically equal in every building.
In practice this raises a few questions that don’t come up on a standalone house:
Who is the guarantee actually issued to?
If one owner instructs a repair to the shared roof, ask whether the written guarantee names the whole common roof or only the specific area serving that flat. This isn’t just paperwork. If the roof is later sold or a different owner has a dispute, a guarantee issued to one person’s name can create real problems establishing who’s covered.
How was the repair agreed?
Depending on the title deeds and the applicable Tenement Management Scheme rules, common repairs can generally be agreed by a majority of owners, with each owner responsible for the share allocated under the relevant arrangements. A roofer who’s used to working on Edinburgh tenements will usually help coordinate this, surveying the roof, producing an itemised quote that can be circulated to all owners, and issuing a guarantee that reflects the shared repair rather than a single flat.
Does a factor need to be involved?
Many tenement blocks are managed by a property factor. Where one exists, the factor typically organises quotes and payment collection for common repairs, and the roofer’s guarantee documentation should go through the same channel so there’s a clear paper trail for every owner, not just the one who made the call.
None of this is a legal requirement of the guarantee itself, but it’s the practical reality of shared Edinburgh roofs, and it’s worth raising with any roofer before agreeing to work.
Listed Buildings and Conservation Areas
Much of central Edinburgh, including large parts of the Old Town, New Town, and Stockbridge, sits within conservation areas, and many individual buildings carry listed status. This affects guarantees indirectly but meaningfully: like-for-like repairs using matching traditional materials, such as Scotch slate or lime mortar, are usually the only option permitted without formal planning consent. That can mean your workmanship guarantee and manufacturer warranty apply to a specific traditional material rather than a modern equivalent, and it’s worth confirming the guarantee explicitly covers the material actually used, not a generic product line.
A Decision Framework Before You Sign
When comparing roofing quotes in Edinburgh, it helps to run through the same short list of questions with every contractor:
- Is the guarantee in writing, and does it specify workmanship, materials, or both?
- How long does each layer of cover last, and does that match what’s typical for the work involved?
- Is there an insurance-backed guarantee available, and is it recommended for the size of this job?
- If this is a shared tenement roof, is the guarantee issued to reflect the whole common repair, or just your flat?
- Does the guarantee cover only the repaired section, or does the contractor make clear what it doesn’t extend to?
- What would invalidate the guarantee, for example unrelated third-party work or missed maintenance?
A contractor who answers all six clearly and puts it in writing is generally a safer bet than one who talks about being “known for quality work” without a documented guarantee to back it up.

Frequently Asked Questions
Q1. How long should a roof guarantee last in Edinburgh?
Answer: It depends on the layer of cover. Workmanship guarantees commonly run 2 to 10+ years, manufacturer warranties often run 10 to 20 years depending on the material, and insurance-backed guarantees typically run up to a 10-year maximum term.
Q2. Does a roof guarantee cover storm damage?
Answer: Usually not. Storm damage, wear and tear, and lack of maintenance are standard exclusions across most roofing guarantees.
Q3. What happens to my guarantee if the roofer goes out of business?
Answer: A standard workmanship guarantee has no value if the company no longer exists. An insurance-backed guarantee is designed specifically for this scenario, since the cover sits with an insurer rather than the contractor.
Q4. Who is responsible for guaranteeing a shared tenement roof in Edinburgh?
Answer: The roof itself is usually common property under the Tenements (Scotland) Act 2004, so the cost and the guarantee should reflect the shared repair agreed by the owners, not just the individual who arranged the work.
Q5. Does a listed building affect my roof guarantee?
Answer: Not the guarantee terms directly, but listed and conservation-area properties are usually restricted to like-for-like materials, so it’s worth confirming the guarantee applies to the specific traditional material used.
Conclusion
A roof guarantee is only useful when it clearly explains what is covered, how long the cover lasts, who provides it and what could invalidate it. For Edinburgh tenement properties, the paperwork should also identify the roof area covered and the person, owners’ group or factor responsible for the repair.
