TL;DR
Quick summary for busy readers — key cost takeaways before you compare contractor quotes.
- The best roofing company for your job is one that is CIF-registered or CIRI-listed, carries public liability insurance, gives you a written quote and has verifiable local reviews.
- There is no single "best" company for all of Ireland. The right one depends on your county, your job type and whether you need planning certification or SEAI-registered insulation work at the same time.
Best Roofing Companies for Roof Replacement in Ireland
Searching for the best roofing companies for roof replacement in Ireland is the right instinct. But choosing on name alone is a mistake.
A company that does excellent work in Finglas may never have worked on a Victorian terrace in Ranelagh. A roofer who is well-reviewed for concrete tile re-roofing may have no experience with natural slate on a period property in Cork city.
The right question is not "who is the best roofer in Ireland?" It is "how do I find the right roofer for my specific job?"
This guide gives you the exact steps to do that. Start with a rough budget using our free roof cost calculator, then read new roof cost Ireland 2026 so you know how quotes typically break down before you sound out contractors.
Step 1: Check the Register First
Before you call anyone, run three checks. They take five minutes total.
CIF — Construction Industry Federation
The CIF is Ireland's main building trade body. Members must follow a code of conduct and carry proper insurance. Search at cif.ie.
CIRI — Construction Industry Register Ireland
CIRI is the competency register recommended by the Competition and Consumer Protection Commission (CCPC). It is the standard most Irish consumer guides point to. Search at ciri.ie.
SEAI — Sustainable Energy Authority of Ireland
If you want to combine your roof replacement with attic insulation and claim a grant, the insulation contractor must be SEAI-registered. Search at SEAI — find a contractor.
Any contractor who is not on at least one of these registers should be able to explain why. If they cannot, move on.
Step 2: Ask These 5 Questions Before You Get a Quote
Ask every contractor the same five questions. Do not vary them. This lets you compare fairly — the same structure we use in how to get roofing quotes in Ireland, so every answer lines up on a like-for-like basis.
1. Are you CIF or CIRI registered?
A yes with a registration number is what you need. Not "we follow all the standards" or "we are fully qualified."
2. Can I see your public liability insurance certificate?
Any roofer working at height on your property must carry at least €2.6 million in public liability cover. Ask to see the certificate. Call the insurer to verify if you have any doubt.
3. Is this quote for a full strip or an overlay?
These are two very different jobs. A full strip removes everything down to the rafters. An overlay lays new tiles over the old structure. They cannot be compared directly on price. You need to know which one you are being quoted.
4. Is scaffolding included or separate?
Most contractors quote scaffolding separately. Ask for the figure upfront so you can compare total costs, not headline costs — many surprises sit in hidden costs of roof replacement.
5. What is your payment schedule?
The correct answer is three stages: deposit at start, payment at midpoint, balance on completion. Any contractor asking for full payment upfront is not operating to industry norms.
Step 3: How to Read Reviews Properly
Google reviews exist for almost every Irish roofing contractor. But not all reviews are equally useful.
Reviews that mean something:
- Mention a specific job type (re-roof, repair, dormer)
- Mention a specific location in Ireland
- Describe what went well and what did not
- Have a response from the contractor
Reviews that mean very little:
- Five stars with only one or two words ("great job", "very happy")
- A cluster of similar-sounding reviews posted within the same week
- No reviews at all on a contractor who claims to have been trading for 10 years
Look for a pattern across 10 or more reviews, not a single standout one.
Boards.ie and AskAboutMoney.ie are also good sources. Irish homeowners who have used contractors often post honest, detailed accounts in the homes and property sections of both sites.

Step 4: What to Check Before Signing Anything
When you receive a written quote, check for all of these before signing.
| Item | Should be included? |
|---|---|
| Full strip or overlay confirmed | Yes |
| Membrane and batten specification | Yes |
| Tile or slate brand and profile | Yes |
| Skip hire included or separate | Confirm either way |
| Scaffolding included or separate | Confirm with figure |
| VAT at 13.5% | Yes |
| Workmanship warranty | Yes — minimum 10 years |
| Payment schedule | Yes — 3 stages |
| Commencement notice | Yes if structural work involved |
| Engineer cert | Yes if structural work involved |
| Start and finish dates | Yes |
A quote missing more than two of these items needs to be queried before you commit.
Red Flags That Rule a Contractor Out
These are not amber flags. These are reasons to move on immediately.
Asks for full payment before work starts.
Legitimate Irish contractors take a deposit of 20–30%, not the full amount.
Quote more than 30% below the other two.
This almost always means something has been left out. Scaffolding, skip hire and the structural contingency are the most common omissions.
Cash only with no VAT receipt.
No VAT receipt means no legal warranty enforcement and no SEAI grant eligibility.
Cannot name their public liability insurer.
This should be instant information. If they have to "check" or "get back to you," they may not have it.
Pressure to sign the same day.
Legitimate contractors understand this is a large purchase. Urgency is a tactic, not a reality.
The Combination That Saves You Money
If your roof is over 15 years old and the attic insulation is thin or outdated, combining a roof replacement with an SEAI-approved insulation upgrade saves you money two ways.
First, the scaffolding is already up. You save one full scaffold hire of €1,200–€2,500.
Second, you can claim an SEAI grant of €1,200–€2,000 depending on your house type. Grant bands change; see our SEAI roof insulation grant overview for current figures and eligibility. The insulation effectively costs you nothing after the grant.
The contractor doing the insulation must be SEAI-registered. This can be your main roofer if they are registered, or a second contractor for the insulation portion only.
Grant approval must come before work starts. Apply at seai.ie — home energy grants.
How Many Quotes Do You Need?
Three. Always three.
One quote gives you a number. Two gives you a comparison. Three gives you enough data to know what a fair price looks like for your job. Our how to get roofing quotes in Ireland hub walks through preparation so those three visits feel structured rather than rushed.
The range between the highest and lowest quote on the same Irish re-roof job is commonly €2,000–€4,000. Knowing where your quotes sit in that range is valuable. Use new roof cost Ireland 2026 as a benchmark for house-type ranges while you compare.

Frequently Asked Questions
How do I find a reliable roofing contractor in Ireland?
Check CIF at cif.ie or CIRI at ciri.ie first. Ask for public liability insurance details. Get three written quotes. Check reviews on Google, Boards.ie and AskAboutMoney.ie for specific job mentions.
What should a roofing quote include in Ireland?
A full line-item breakdown covering: full strip or overlay, materials specification, scaffolding, skip hire, VAT at 13.5%, payment schedule and workmanship warranty.
Is the cheapest roofer the biggest risk?
Not always. A quote that is 10–15% below the others can be competitive pricing. A quote that is 30% below almost always means something has been excluded. Check exactly what is and is not included before comparing.
Do I need a CIF or CIRI registered roofer?
You are not legally required to use one. But registration means the contractor has agreed to industry standards and insurance requirements. The CCPC specifically recommends checking the CIRI register before hiring any builder in Ireland.
How long should a roofing warranty last in Ireland?
A minimum of 10 years on workmanship is reasonable. Many established Irish contractors offer 15–20 years. Material warranties from tile manufacturers are separate and typically run 20–40 years depending on the product.
