I’ve been repairing and replacing roofs across Cork for over 15 years. In that time I’ve been called out to more jobs than I can count where a homeowner has already been burned — paid a deposit to someone who disappeared, had work done that failed within a season, or been talked into a full replacement when a straightforward repair would have done the job properly.
It happens more often than it should, and it happens because most homeowners don’t know what to look for when choosing a roofer. Roofing isn’t like buying a car or a washing machine where you can research the product independently. You’re hiring a person and a team to do skilled work on one of the most important parts of your home — and you’re often doing it under pressure, after a storm or a leak has already caused damage, when you just want someone to sort it quickly.
That pressure is exactly what certain operators exploit.
This guide is my honest attempt to level the playing field. By the end of it you’ll know exactly what to look for in a Cork roofer, what the red flags are, and what questions to ask before anyone sets foot on your roof. I’ll be straightforward about what Hallmark Roofing does and doesn’t do — and you can judge us by the same standards I’m laying out here.
Cork has no shortage of people calling themselves roofers. Some are excellent — skilled, qualified, insured tradespeople who take genuine pride in their work and stand over it. Some are competent but unreliable — they do good work when they show up but communication is poor and timelines are unpredictable. And some — a small but significant minority — are actively operating in a way that damages homeowners financially.
The problem is that from the outside, before any work has been done, it can be genuinely difficult to tell the difference. A professional-looking website, a van with a logo on the side, and a confident manner on the phone costs nothing and tells you very little about the quality of the work or the integrity of the person doing it.
Cork’s roofing market also has a seasonal dynamic that makes the problem worse. After a significant Atlantic storm — the kind that removes slates, lifts ridge tiles, and brings homeowners out into the garden to stare worriedly upward — the volume of calls to roofers across Cork spikes dramatically. Established, reputable businesses fill up quickly. That creates a gap that less scrupulous operators are very good at filling.
The good news is that the signs of a reliable roofer and the red flags of an unreliable one are consistent and recognisable once you know what to look for.
This sounds basic but it matters more than almost anything else. A roofing contractor with a genuine, verifiable business address in Cork is accountable in a way that someone operating from a mobile number and a van simply isn’t.
A fixed address means there’s a business to go back to if something goes wrong. It means the contractor is embedded in the local community — their reputation is local and they have something to lose by doing poor work. It means you can verify that the business exists independently of a website.
Check that the address is real. Type it into Google Maps. Look for a Google Business Profile listing that matches the address and has genuine reviews. A PO box is not a business address. A residential address registered as a business is worth investigating further.
At Hallmark Roofing our address is North Point Business Park, New Mallow Rd, Cork, T23 AT2P. We’ve been operating from Cork for over 15 years and every job we do is in our own backyard. Our reputation here is the only one we have.
Public liability insurance is non-negotiable for any roofing contractor working on your property. It protects you if something goes wrong — if a tile falls and damages a car, if a worker is injured on your property, if damage occurs to your home during the work. Without it, you could be personally liable for costs that should never come anywhere near you.
The problem is that saying you’re insured and being insured are two different things. Anyone can claim to have insurance. What you want is proof.
Ask every contractor you’re considering for their certificate of insurance before work begins. A legitimate, properly insured contractor will produce this without hesitation. It should show the name of the insurer, the policy number, the level of cover, and the expiry date. Check that it’s current — not expired. Check that the name on the policy matches the name of the business you’re hiring.
If a contractor is reluctant to provide insurance documentation, treat that as a serious red flag regardless of how reasonable their price or how confident their manner.
Hallmark Roofing carries full public liability insurance and we’ll provide our certificate to any customer who asks for it. We’re also members of the National Guild of Craftsmen — an independently verifiable trade membership that requires members to meet standards of qualification and professional conduct.
Reviews are one of the most reliable signals available when assessing a roofer — if they’re genuine. Google reviews that include specific details about the job, the property, the people involved, and the outcome are far more credible than generic five-star ratings with one-line comments. Genuine reviews mention the roofer by name, describe the specific problem that was fixed, and often note something particular about the experience.
Look at the overall pattern as well as individual reviews. A business with 50 reviews accumulated steadily over three or four years is a more reliable signal than one with 20 reviews all posted in the same month. Check whether the business responds to reviews — both positive and negative. How a business handles a negative review tells you a great deal about how they’ll handle any issues that arise with your job.
Also check whether the reviews appear on Google specifically — Google’s verification process makes it significantly harder to post fake reviews than on some other platforms. A strong Google review profile with consistent ratings over time is a meaningful trust signal.
At the time of writing Hallmark Roofing has 39 verified Google reviews with a 5-star rating. We’re proud of those reviews and we’d ask you to read them — not just the rating but the content of what customers have said about the actual experience of working with us.
Never agree to roofing work on the basis of a verbal quote. This is the single most important practical piece of advice in this entire guide and it’s the one most commonly ignored because it feels awkward to insist on when someone is standing in your garden telling you what needs doing.
A written quote protects you in several ways. It establishes exactly what work is being carried out before anyone starts. It prevents the cost from expanding unexpectedly once the job is underway — a practice sometimes called scope creep where work that wasn’t discussed gets added to the bill. And it gives you something concrete to compare between contractors.
A proper written quote should include the specific work being carried out in clear language — not just “roof repairs” but what specific repairs, to what area, using what materials. It should include the total cost inclusive of VAT. It should specify what isn’t included — for example whether scaffold is additional or included. And it should give you a timeline for when the work will be done.
If a contractor won’t provide a written quote, don’t hire them. If a contractor provides a quote that is vague about scope, ask for clarification in writing before proceeding. If the final invoice is significantly higher than the written quote without prior discussion and agreement, you have a legitimate dispute.
At Hallmark Roofing we provide written quotes after every free inspection, with a full breakdown of the work. What we quote is what you pay. If we encounter something unexpected during a job — and occasionally on older Cork properties we do — we stop and discuss it with you before proceeding. We don’t complete extra work and present a larger bill.
A reliable roofer will tell you what your roof needs, explain why, give you a written quote, and leave you to make a decision in your own time. They will not tell you that the price is only valid for 24 hours. They will not tell you that your roof is in imminent danger of collapse and needs to be fixed immediately. They will not follow up repeatedly and aggressively after giving you a quote.
These pressure tactics are a red flag regardless of how reasonable the price seems. A contractor who uses urgency and pressure to close a sale is telling you something important about how they operate — and it’s not something you want to find out after you’ve paid a deposit.
This doesn’t mean urgency is never legitimate. After a significant storm, a roof that has been genuinely damaged does need attention promptly. But a legitimate contractor will explain the specific reason for urgency — “this section is open to the weather and needs temporary waterproofing before the next rain” — rather than creating vague anxiety about the general state of the roof to push you into a quick decision.
Roofing is a specialist trade. The skills required to repair a Victorian slate roof correctly, install GRP fibreglass on a flat roof properly, or rebuild a chimney stack that will last 30 years are not the same skills used in general construction or property maintenance. A general builder who “also does roofs” is not the same as a specialist roofing contractor — and the difference shows in the quality and longevity of the work.
Ask specifically about experience with the type of work you need done. If you have a period property with original Irish slate, ask whether they have experience sourcing and matching reclaimed slate and working with lime mortar. If you need a GRP flat roof, ask how many they’ve installed. If you’re on the coast and need flashing work, ask about their experience with the specific challenges of coastal salt air exposure.
A qualified, experienced roofer will answer these questions specifically and confidently. Vague answers about “lots of experience with all types of roofing” without any specific detail are worth probing further.
How a contractor communicates before the job starts is a reliable indicator of how they’ll communicate during and after it. Do they answer their phone or return calls promptly? Do they turn up for the inspection when they said they would? Do they explain what they find clearly and in plain language? Do they give you a timeline and stick to it?
Small failures of communication before the job starts — missing a call-back, arriving late for an inspection without explanation, being vague about when they can start — tend to become larger failures of communication once the job is underway. The best predictor of future behaviour is past behaviour, and the period before work starts is your best opportunity to assess this.
Asking for a deposit before work begins is normal and legitimate — most roofing contractors ask for a percentage upfront to cover materials. What isn’t normal is demanding a large cash deposit — particularly in cash specifically rather than by bank transfer or card — before any written quote has been provided.
The standard practice for legitimate roofing work in Ireland is a deposit of 20–30% of the total job value, paid after a written quote has been signed off, with the balance paid on satisfactory completion. Any request for significantly more than this upfront — particularly for cash — is a serious red flag.
We’ve been called out to properties where a homeowner has paid a 50% or even full cash deposit to someone they found on Facebook or through a leaflet, and that person has either not returned or done partial work of poor quality and disappeared. This happens in Cork every year. A written contract and a reasonable deposit structure protects you from this.
A mobile number and a Facebook page is not a business. If you cannot find a physical business address, a registered company name, or a verifiable Google Business Profile for a roofing contractor, treat that as a significant warning sign.
This doesn’t mean every legitimate small roofing operation has a large premises — many excellent sole traders work from a home address. But a genuine business operating legitimately will have verifiable contact details beyond a mobile number, and the people running it will be identifiable by name with a traceable local presence.
Door-to-door solicitation after a storm — where someone knocks on your door, tells you they’ve noticed damage to your roof, and offers to fix it immediately — is one of the most consistent patterns associated with roofing scams in Ireland. The technique is designed to exploit the anxiety that storm damage causes and to rush you into a decision before you’ve had time to research the contractor or get alternative quotes.
Legitimate roofing contractors in Cork do not generate business by cold-calling houses after storms. If someone knocks on your door with this approach, ask for their business name, address, and insurance details in writing before engaging with them further. Do not let them onto your roof to inspect it and do not pay any money until you have independently verified their credentials.
Roofing materials and skilled labour cost what they cost. A quote that is significantly below the market rate for a given job is almost always an indicator that something is wrong — either the scope of work is much less than you think it is, the materials being used are substandard, the contractor is uninsured and operating without proper business costs, or the work simply won’t be done to the standard required.
This doesn’t mean the most expensive quote is always the best. It means that if you have three quotes and one is dramatically cheaper than the other two, it’s worth understanding specifically why before accepting it.
As covered above — a legitimate, properly insured contractor will produce their certificate of insurance without hesitation. Vague reassurances that they’re “fully insured” without being willing to show documentation should be treated with caution. The same applies to qualifications and trade memberships — these should be verifiable independently, not just claimed verbally.
Any contractor who resists putting a quote in writing — who wants to agree on a handshake, who says the price depends on what they find and they’ll let you know at the end, who says they’re too busy to do paperwork — is creating a situation where you have no protection if the cost expands unexpectedly or the work isn’t done properly.
There is no legitimate reason for a professional roofing contractor to refuse to provide a written scope of works and a fixed price. If they won’t put it in writing, don’t give them the job.
Armed with everything above, here are the specific questions to ask every contractor you’re considering. The answers — and crucially, how readily and specifically they’re given — will tell you most of what you need to know.
Can you provide your certificate of public liability insurance? A yes with immediate follow-through is the right answer. Any hesitation is a red flag.
Do you have a fixed business address in Cork? Get the address and verify it independently on Google Maps and Google Business Profile.
Can I see examples of similar work you’ve done and speak to a previous customer? Established contractors will have a gallery of completed jobs and will be comfortable with reference requests. A reluctance to provide references is worth noting.
Will you provide a written quote with a full scope of works before any work begins? The answer should be an unqualified yes.
What deposit do you require and how do you accept payment? A reasonable deposit — 20–30% — paid by bank transfer after a written quote is the norm. Cash-only operators should be treated with caution.
Are you a member of any trade body or industry association? Membership of the National Guild of Craftsmen, the Construction Industry Federation, or a similar body is independently verifiable and a positive signal.
What guarantee do you provide on the work? A written workmanship guarantee is standard practice for quality roofing contractors. Ask what it covers and for how long.
Who specifically will be carrying out the work — your own employees or subcontractors? This matters because the quality control on subcontracted work is harder to maintain. Knowing whether the person giving you the quote is also the person doing the job — or overseeing it directly — gives you a clearer picture of accountability.
Getting multiple quotes is sensible and we’d encourage it. But comparing quotes on price alone without understanding what each one includes is a common source of problems.
Two quotes for the same apparent job can be very different things. One contractor might be quoting for a patch repair. Another might be quoting for a proper repair that addresses the root cause. One might be quoting for capping a failing fascia. Another might be quoting for full removal and replacement. One might include scaffold in the price. Another adds it at the end.
When comparing quotes, compare the scope of work as carefully as you compare the price. Ask each contractor to explain specifically what their quote includes and what it doesn’t. If one quote is significantly cheaper, ask the contractor directly to explain why — a good contractor will be able to tell you exactly what accounts for the difference.
The cheapest quote is not always the worst choice and the most expensive quote is not always the best. What you want is the quote that represents the best value — the work that actually needs doing, carried out properly, by someone who will stand over it.

Look for: a fixed Cork address, verifiable public liability insurance, genuine Google reviews with specific detail, a written quote with full scope of works, no pressure tactics, specialist roofing experience, and clear communication from the first contact.

Ask: for the insurance certificate, for the business address, for references, for a written quote, for the deposit and payment terms, for trade body membership, for a written guarantee, and for clarity on who specifically will do the work.
