A warranty length is the number everyone advertises. It’s rarely the number that matters when a leak actually happens. Homeowners see “25 years” and assume full coverage, when in practice most warranties narrow sharply once you look at what’s actually included versus excluded: labour versus materials, specific causes of failure, conditions like yearly inspections that need to happen for the warranty to stay valid at all.

This piece walks through how to actually evaluate a roofing warranty on its real terms, using our own warranty structure at Shield Edge as a working example, without pointing fingers at any specific competitor. The goal is the same as always: help you read any warranty, not just ours, and understand what promise you’re actually being given.

1. What a “10-year warranty” actually covers, and what it doesn’t

When we say 10-year warranty on a roof waterproofing or heatproofing job, here’s exactly what that means: it covers our workmanship, the installation itself, for a full 10 years from the day the job is completed. Coverage doesn’t shrink over time either. Year 1 and year 10 are treated the same. If the coating or membrane fails because of how it was put on, we come back and fix it at no cost to you.

What it doesn’t cover is the material itself. The membrane and coating products we use, from manufacturers like Sika, Fosroc, MAPEI, Dow, and Tengyu, carry their own separate manufacturer warranties against material defects. If something fails because the material itself was faulty rather than how it was installed, that’s a different claim, and we help you make it directly against the manufacturer.

It’s also worth knowing this 10-year term is specific to roof waterproofing and heatproofing. For trades like plumbing, electrical, HVAC, and renovation work, our workmanship warranty runs 12 months on the specific issue that was repaired, not 10 years. Always check which term applies to which part of a job. A single quote covering multiple trades can quietly carry more than one warranty length inside it.

2. The thing homeowners assume is covered that almost never is

Two things trip people up more than anything else:

• Damage caused by something other than the original work. A roof coating warranty covers the coating failing on its own. It doesn’t cover a leak caused by storm damage, structural movement in the building, another contractor drilling into the roof for a satellite dish or a new AC unit, or drains that were never cleared and eventually caused water to back up. The warranty is a promise about the work holding up under normal conditions, not a promise that nothing bad will ever happen to your roof again.
• Damage the leak caused elsewhere in the house. If a covered defect causes a leak, the warranty pays to repair the defect itself. It typically doesn’t extend to the ceiling paint, flooring, or furniture that got damaged as a result. That catches people off guard, but it’s standard across the industry. If a contractor promises a warranty that covers everything downstream of a leak, that’s worth a second look rather than instant reassurance.

3. Is a 25-year warranty always better than a 10-year one?

Not automatically, and this is really the heart of the whole question. A warranty’s length only tells you something once you know what it covers, what can cancel it, and whether the company will realistically still be around and honoring it 15 or 20 years from now.

A few things worth checking before comparing two numbers side by side:

• Is it workmanship, materials, or both? A 25-year materials warranty backed by a manufacturer is a different kind of promise than a 10-year workmanship warranty from the installer. A quote that just says “25 years” without saying which one applies is telling you less than it sounds like.
• What keeps it valid? A long warranty that gets voided by something routine, like missing a single inspection, isn’t worth as much as it looks on paper. See the next section for what usually does this.
• Who’s actually behind the promise? A company that’s been operating for a year or two isn’t a credible source of a 25-year guarantee, no matter what the paperwork says. A shorter warranty from a contractor with a real track record is often the safer bet in practice.

We set ours at 10 years for waterproofing and heatproofing because that’s a term we’re confident standing behind on our own installation, with coverage that doesn’t shrink and no fine print built to get us out of a legitimate claim. Longer isn’t automatically better. Clearly defined and actually enforceable is better.

4. The conditions that can void a warranty nobody mentions upfront

This is where most of the fine print actually lives. Ours is voided by:

• Storm damage, extreme weather, fire, or other acts of nature
• Structural movement or building defects unrelated to the work that was done
• Damage caused by another contractor, whether that’s other trades working on the roof, unauthorized rooftop work, or later modifications by someone else
• Neglect, such as drains that were never cleared or maintained
• Misuse, vandalism, or foot traffic and equipment damage outside the agreed scope of the job
• Repairs or alterations carried out by anyone other than the original contractor

The condition that surprises people the most is this one: our warranty requires an annual check-in to stay active. Once a year we reach out to schedule a quick visual inspection, or you can send photos if that’s easier, at no cost to you either way. Skip enough of these and you risk the coverage lapsing. Not because we’re looking for a reason to say no, but because a roof that hasn’t been looked at in years makes it very hard to prove a failure came from the original installation rather than years of unmonitored wear and tear. Before signing anything, ask specifically whether a warranty has a maintenance or inspection requirement attached to it. It’s one of the most common ways coverage quietly lapses without the homeowner ever realizing it happened.

5. What to keep on hand in case you need to make a claim

If a leak shows up years into a warranty period, having the right paperwork ready makes the difference between a same-day fix and a drawn-out argument about whether it’s actually covered.

• The original invoice or contract, showing the work that was done and the completion date, so it’s clear the issue falls inside the warranty period.
• A record of your annual check-ins, confirming inspections happened on schedule or that photos were sent when requested. This is the condition that keeps the warranty active, so proof it was met matters.
• Photos of the problem as soon as you notice it, dated if possible. This matters even more if there’s any chance the cause could be disputed, for example a leak appearing shortly after a different contractor worked on the roof.
• Any record that you kept up basic maintenance, like clearing drains, since neglect is one of the more common reasons a claim gets questioned.

From there the process should be simple. Contact the contractor, they inspect the issue (with us, that’s the same day for an active leak and within two business days for a routine claim), and if it’s covered, the repair happens at no cost to you. Keeping that paperwork isn’t about distrust. It’s what turns a 10-year promise into something that actually gets acted on quickly, years after the job is finished, instead of becoming an argument.

6. What happens to the warranty when you sell the villa

Most homeowners never think to ask this until they are selling, and by then the answer matters. Our warranty is not transferable. It is issued to the client on record and it runs for as long as that person owns the property. A new owner does not inherit it.

That is worth knowing in both directions. If you are selling, the roof work still helps you: you have dated photographs, a written scope and a record of annual checks, which is far stronger evidence for a buyer than a warranty certificate with someone else’s name on it. If you are buying a villa and the seller mentions a roof warranty, ask whose name it is in and whether it transfers, because with most contractors here it does not.

Ask any contractor the transfer question before you sign, not after. It is one of the quickest ways to find out whether they have actually thought about their own terms.

7. The annual check-in, and why one exists at all

Our warranty stays active on one condition: a check-in once a year. It is a short visual inspection, or photographs you send us yourself if that is easier. There is no cost, and there is no catch.

The reason is simple. Most roof failures we are called to are not sudden. They start as a blocked drain, a lifted edge or a hairline crack at a pipe, and they spend months getting worse out of sight. A yearly look catches those while they are still a ten-minute fix rather than a soaked ceiling.

Be careful with conditions that are not like this one. There is a difference between a contractor asking for a free annual look and a contractor requiring paid annual servicing to keep cover alive. The second is a maintenance contract wearing a warranty’s clothes. Ask which one you are being offered, and ask what happens if you miss a year.

8. How to test a warranty that promises 15, 20 or 30 years

Longer numbers are common in Dubai roofing, and a longer number is not automatically a better promise. Put any warranty, ours included, through these questions and the difference shows up fast.

• Workmanship, materials, or both? Many long warranties are the manufacturer’s cover on the product, passed along. That protects you if the tin was faulty, not if the coating was applied badly. Poor application is the far more common failure.
• Who honours it? A 20-year promise is only as good as the company still being reachable in year nine. Ask how long they have traded, and check the licence.
• Does cover shrink over time? Some warranties reduce what they pay year by year. Ours treats year one and year ten the same. Ask for that in writing.
• What voids it? Every warranty has exclusions. The question is whether they are handed to you up front or discovered at claim time.
• Is it transferable? See section 6.
• How fast is a claim answered? A promise with no response commitment is not much of a promise. Ours is same day for an active leak and within two business days for a routine claim.
• Is it written down? If the warranty exists only in a WhatsApp message or a line on a quote, you do not have a warranty. You have a sentence.

A 10-year workmanship warranty from a licensed company with a real claims process is worth more than a 30-year figure on a leaflet. The number is marketing. The terms are the product.

9. Warranty questions, answered

What does a 10-year roofing warranty in Dubai actually cover?

Our 10-year warranty covers workmanship, meaning the installation itself, for the full ten years from completion. Cover does not shrink over time. Materials carry their own manufacturer warranties from Sika, Fosroc, MAPEI, Dow and Tengyu, and we help you claim against those if a material defect is at fault.

Is a 25-year roofing warranty better than a 10-year one?

Not automatically. What matters is whether it covers workmanship or only materials, whether cover shrinks over the years, what voids it, how quickly a claim is answered, and whether the company will still be trading to honour it. A longer number with narrower terms is worth less than a shorter one with clear terms.

What voids a roof waterproofing warranty?

Commonly: storm damage and extreme weather, fire and other acts of nature, structural movement or building defects unrelated to the work, damage caused by other contractors or unauthorised rooftop work, neglect such as blocked drains, misuse or foot-traffic damage outside the agreed scope, and repairs or alterations carried out by anyone else.

Does the warranty transfer if I sell my villa?

Ours does not. It is issued to the client on record and lasts as long as they own the property. If you are buying a villa with roof work done, ask whose name the warranty is in and whether the contractor transfers it.

What do I have to do to keep the warranty active?

One check-in a year. That is a short visual inspection, or photographs you send us. There is no cost, and there is no requirement to buy paid servicing to keep cover alive.

How quickly is a warranty claim handled?

Same-day response for an active leak, and within two business days for a routine claim. The warranty covers repairing the defect itself, not consequential damage to contents or finishes, which is what home insurance is for.
