Ten years from completion
Given by K & M Roofing Solutions on all work, running from the day the job is finished rather than from the invoice date. It covers how the work was carried out.
Guarantee
Our 10-Year Workmanship Guarantee
Every completed job carries a 10-year workmanship guarantee, issued in writing. This page sets out what that means, what it covers and what it does not.
Ask us about the guaranteeWhat a workmanship guarantee actually is
A workmanship guarantee is the contractor standing behind the way the work was carried out. K & M Roofing Solutions gives one on all work, it runs for 10 years from the day the work is completed rather than from the date of the invoice, and it is issued in writing as a certificate when the job is signed off rather than promised verbally and forgotten.
It is worth being precise about what that covers, because the word guarantee gets used loosely in this trade. A workmanship guarantee covers the installation: how the system was prepared, laid, detailed and terminated. If an upstand was formed badly, an outlet was not dressed in properly or a lap was not made correctly, that is workmanship and it is what this guarantee is for.
What it does not cover is the material itself, because we did not make it. That is a separate guarantee from a separate party, and the difference matters most at exactly the moment you need to rely on one of them.
One thing worth knowing early, because it is the part owners most often do not realise they have: the guarantee belongs to the property rather than to the person who paid for the work. If you sell, it passes to whoever buys the house, for whatever is left of the ten years. That makes the certificate a document worth keeping with the deeds. A buyer asking what has been done to the roof is a great deal easier to answer with a dated certificate naming the work and the system than with a receipt and a recollection.
Benefits
What you get, and from whom
A second guarantee on HYDRONYLON
Flat roofs finished with HYDRONYLON also carry a separate 10-year product guarantee issued by HYDRONYLON LTD, which covers the system itself.
It stays with the property
The guarantee attaches to the building rather than to whoever paid for the work, so it passes to the next owner with whatever is left of the ten years. It is worth something at sale rather than ending at it.
A certificate, not a promise
You get a signed guarantee certificate at sign-off naming the property, the work, the system used, the completion date and what is covered. It is the document you hand to a buyer.
What we offer
Workmanship and product: the difference
Two guarantees, two issuers, two different things going wrong. Understanding which is which is the whole subject.
The workmanship guarantee, from us
Ten years from the completion of the work, on all work, issued by K & M Roofing Solutions as a signed certificate. It answers the question of whether the job was done properly: preparation, application, the details at every upstand, outlet, abutment and termination. Most roof failures are workmanship or detailing rather than material, which is why this is the guarantee that gets used.
The product guarantee, from the manufacturer
On a flat roof finished with HYDRONYLON there is a second, separate 10-year guarantee issued by HYDRONYLON LTD covering the system itself. HYDRONYLON LTD manufactures it and holds the ETA-23/0735 certification; K & M Roofing Solutions is a certified applicator. Two different companies, two different documents, and the product guarantee stands independently of us.
See the liquid waterproofing system this applies toWhy applicator approval matters to both
A manufacturer will not guarantee its system against an installation it did not approve, so a product guarantee is normally conditional on the work having been done by a certified applicator. That is the practical reason to ask any contractor which manufacturer has approved them, rather than taking the certification on the tin as though it transferred automatically.
Read what the certification actually coversYour guarantee certificate
Issued at the end of the job and signed. It carries our company details and yours, the address of the property, a description of the work carried out, the system or material used, the date the work was completed, the guarantee period and the date it starts from, and what the guarantee covers and excludes. On a flat roof finished with HYDRONYLON there is a second certificate alongside it from the manufacturer. Keep both with the property paperwork: they go to the next owner when you sell.
Manufacturer warranties on other products
Where a job includes components made by somebody else, windows, boilers, decking boards or roofline products, those carry their own manufacturer warranties on their own terms. We pass the documentation on to you at handover rather than folding it into ours, because those are agreements between you and the maker.
Scope
What a workmanship guarantee does not reach
- Mechanical damage, whether accidental or deliberate
- Damage caused by other trades working on or across the roof
- Storm, flood, fire and other events outside anyone's control
- Deterioration from maintenance that was not carried out
- Blocked gutters and outlets left until water backs up
- Damage caused by work someone else carried out after we finished
- The material itself, which is the manufacturer's guarantee, not ours
- Parts of the roof we did not work on
How it works
How to raise a guarantee claim
1
Phone or email us
There is no form to fill in, no reference number to quote and no claims department to get past. You contact us the same way you did the first time, on either of the numbers or the office email address.
2
Give us three things
The address of the property, roughly when we carried out the work, and photographs of what you are seeing. The photographs do more than a description, particularly of where water is showing inside. If water is actively coming into the building, phone rather than email.
3
We come and look at it
We arrange a visit and inspect the roof. The first question is always what is actually happening, because a new problem on a roof we worked on is not automatically the work we did. It might be, and if it is we will say so.
4
You get a straight answer either way
If the cause is our workmanship, it is covered and we put it right. If it is something else, a different part of the roof, a gutter, or work a later trade carried out, we tell you what it actually is and what putting it right involves, and you decide what to do.

Common questions
Frequently asked questions
The way the work was carried out. That means the preparation, the application and the detailing: upstands, outlets, laps, abutments, terminations and everything else that decides whether a roof stays watertight. K & M Roofing Solutions gives it on all work and it runs for 10 years from completion, issued in writing at sign-off. Most roof failures are a detail rather than a material, which is why the workmanship guarantee is the one that matters in practice.
Who gives it and what it covers. A workmanship guarantee comes from the contractor and covers the installation. A product guarantee comes from the manufacturer and covers the material. They are separate documents from separate parties, and they protect against different failures: an installation fault is not a material fault, and a manufacturer will not pay to correct somebody else's work. On our flat roofs finished with HYDRONYLON you have both, which is a stronger position than either on its own.
HYDRONYLON LTD, the manufacturer, not us. Flat roofs finished with HYDRONYLON carry a separate 10-year product guarantee issued by them, covering the system itself. HYDRONYLON LTD manufactures the system and holds its ETA-23/0735 certification; K & M Roofing Solutions is a certified applicator, trained and approved by them to install it. The distinction matters because that separate guarantee stands independently of us, and because a manufacturer normally issues one only where an approved applicator carried out the work.
Anything that is not about how we did the work. Mechanical damage, whether accidental or deliberate. Damage caused by other trades on the roof, which is more common than people expect on flats and commercial buildings. Storms, floods and other events nobody controls. Deterioration that follows from maintenance not being done, a blocked outlet left until the roof holds water being the usual example. Alterations or repairs somebody else made afterwards. And parts of the roof we did not work on, which is worth being clear about where a repair sits alongside older work.
It covers the part we worked on. Where we carry out a repair rather than a full refurbishment, the guarantee applies to that repair rather than adopting the condition of the whole roof, and we are explicit about that at quotation stage rather than leaving it to be discovered later. If the survey shows the rest of the covering is close to the end of its life, we will tell you at the time, because that changes what a repair is worth to you.
Yes. The guarantee is attached to the property rather than to the person who paid for the work, so it passes to the next owner with whatever is left of the ten years, and there is nothing to register or apply for. That is worth more at sale than most owners expect: a buyer asking what has been done to the roof is much easier to answer with a dated certificate naming the work, the system and the completion date than with a receipt and a recollection. Hand the certificate over with the rest of the property paperwork.
From the completion of the work, not from the date of the invoice. The completion date is written on your guarantee certificate, so there is nothing to work out or argue about later. Where a flat roof is finished with HYDRONYLON, the separate 10-year product guarantee issued by HYDRONYLON LTD comes with its own document and its own dates.
Our company details and yours, the address of the property, a description of the work we carried out, the system or material used, the date the work was completed, the guarantee period and the date it runs from, what is covered and what is excluded, and a signature. On a flat roof finished with HYDRONYLON there is a second certificate alongside it, issued by the manufacturer and covering the system itself. Keep both with the property paperwork, because they are what you hand to a buyer and what a surveyor will ask to see.
No, and this is worth being clear about because plenty of guarantees in this trade are written to fall over at the first opportunity. Ours is not cancelled as a whole because another contractor has been on the roof. What is not covered is damage caused by that work, which is a different thing. Where somebody else has worked on a roof we guaranteed, we come and look at it before taking the claim any further, so that what we are looking at is established rather than assumed. If the fault is ours it is covered as normal.
Phone or email us with three things: the address, roughly when we carried out the work, and photographs of what you are seeing. There is no form, no reference number and no claims department to get past; you contact us the same way you did the first time. We then arrange a visit and look at the roof, because a new problem on a roof we worked on is not automatically the work we did. If it is our workmanship, it is covered and we put it right. If it is something else, we tell you what it actually is rather than leaving you to find out from somebody else. If water is coming into the building now, phone rather than email.
Yes, and they are different things covering different risks. A guarantee is our commitment to stand behind the work. Insurance covers damage and liability arising while we are carrying it out. We provide our insurance documentation to managing agents, block managers and commercial clients before starting on site as a matter of course, along with method statements where the building requires them.
