Not long ago we quoted a homeowner for a roof repair, took a deposit, and ordered in the materials. The job was booked. Then a text landed: the roofer who'd done the house next door said he'd do it for a good bit less, and our customer wanted to back out.
His worry was fair enough. To him it looked like a quick one-day job, and our number felt high for a single day's work.
So the next morning I rang him. Not to pressure him — to explain. By the end of the call he understood exactly what he was paying for, and the job went ahead. Here's that same explanation, written down, for anyone staring at two roofing quotes and wondering why one is so much higher than the other.
A higher roofing quote usually means more is actually included: a proper inspection, better materials, full preparation, a complete clean-up, and a guarantee the roofer will honour. The cheaper number often leaves some of that out. That gap usually reappears later — as "extras" mid-job, or a second repair bill when the first one fails. In Dublin, where roofs take 750mm+ of rain a year, the repair that's done once is almost always the cheaper one in the end.
What You're Actually Paying For
Two quotes for "the same job" are rarely the same job. The total is just the last line. The value is everything above it.
Here's what sits inside a proper roof repair quote — and what a rock-bottom price often quietly drops.
The inspection the price is built on
Our number comes from getting up and actually looking. A proper roof inspection tells us where the water really gets in, not just where the stain shows.
A price given at the door, without anyone climbing up, isn't a quote. It's a guess. And guesses only move one way once work starts.
Materials that suit Irish weather
Dublin roofs deal with 750mm+ of rain a year, plus wind-driven downpours off the Atlantic. Bargain membranes and low-grade fixings don't last in that.
We price for materials that hold up. The cheaper quote sometimes prices for materials that don't.
Proper preparation
Good roofing is mostly preparation. Raking out failed mortar, clearing the area, drying and checking the timber underneath, setting up safe access.
Skip the prep and the repair looks fine for a fortnight — then fails at the first weak point.
A full clean-up
We leave a site as tidy as we found it. Old slates, nails, mortar and debris go with us, not into your garden.
That's labour and disposal that has to be costed somewhere. If it's missing from the cheap quote, it's either skipped or coming back as an extra.
A guarantee that's actually honoured
Every repair we carry out is backed by our 10-year workmanship guarantee. If something we did isn't right, we come back and sort it.
A guarantee is only worth anything if the roofer is still answering the phone next winter. That's the part you can't see on a quote — but it's the part that matters most.
The "One-Day Job" Is Really a Multi-Day Job
This is the bit most homeowners never see, and it's exactly what I explained on that phone call.
You see one day of work on the roof. Behind that day sit four or five.
- The inspection. A trip out to climb the roof, find the real fault, and measure up properly.
- Sourcing the materials. Collecting the right tiles, lead, mortar or membrane for your specific roof — not whatever's nearest in the van.
- Preparation. Safe access, stripping back the failed area, checking what's underneath.
- The repair itself. The day you actually see us up there.
- The clean-up. Clearing the site and hauling the waste away.
So the "one day" you're picturing is the visible tip of the job. The price reflects the whole thing — the work you see and the work that makes it last.
Why the Cheaper Quote Can Get More Expensive Mid-Job
Here's a pattern worth knowing about, because it catches good people out.
When a price is handed over without a proper look, there's nothing holding it in place. So once the work begins, the conversation can change.
Sometimes it's "while we're up here, you also need…". Sometimes it's "we can't finish this unless we sort that first" — with a new cost attached. The headline price that won the job quietly climbs past the honest quote it beat.
I'm not saying every cheaper roofer does this. But a number set without an inspection has only one direction to travel once the work is underway, and it isn't down. For the deeper read on the corners cheap quotes cut, we wrote a full guide on why cheap roofers cost more next winter.
What "We Stand Over It" Actually Means
"We stand over our work" is easy to say. Here's what it actually means with us.
- A 10-year workmanship guarantee on the repair, in writing.
- Reviews and repeat customers across Dublin you can check before you commit.
- A local team based in Dublin 15 — we work Castleknock, Blanchardstown and Clonsilla week in, week out, so our reputation travels with us.
- Fully insured, so you're covered while we're on your roof.
A roofer who plans to be around in ten years prices like it. A crew passing through doesn't have to.
What Genuinely Moves a Roofing Quote Up or Down
Not every difference between two quotes is about quality. Some of it is just the roof. Being upfront about that is part of an honest quote.
The real cost variables are:
- Access and scaffolding — height, pitch, and whether the team can work safely without it.
- Lead weight and detailing — chimneys, valleys and flashings take skilled, time-consuming work.
- Material choice — matching your existing tiles or slates, and the grade of membrane and fixings.
- The scope we find at inspection — what's actually failing, not just the visible symptom.
And to be clear, a fair quote isn't the dearest one either. By staying local and keeping our overheads lean, we can price keenly without cutting corners. You can sanity-check realistic numbers in our Dublin roof repair cost guide.
How to Compare Two Roofing Quotes Fairly
If you're holding two quotes right now, don't compare the totals. Compare the jobs. A few minutes here saves a lot later.
How to Sense-Check a Roofing Quote Before You Sign
Simple, ground-level checks to compare two roofing quotes fairly and avoid hidden costs.
Supplies Needed:
- Both written quotes
- Notebook
Tools Needed:
- Phone
Step 1: Put both quotes side by side
Lay them out together and read what each one actually includes, not just the price at the bottom.
Step 2: Check each price came from an inspection
Ask whether the roofer got up on the roof. A price given without a proper look is an estimate, not a quote.
Step 3: Compare what is included, line by line
Look for materials, safe access or scaffolding, waste removal, clean-up, and the guarantee — not just labour.
Step 4: Ask what happens if they find more damage
A straight answer means a fair process. A vague one often means the low price will climb once work starts.
Step 5: Check the guarantee and the reviews
A written workmanship guarantee and real local reviews tell you the roofer plans to stand over the job.
Frequently Asked Questions
Comparing Roofing Quotes: FAQs
Usually because it includes less. A very low quote often skips the inspection, uses cheaper materials, or leaves out access, waste removal, clean-up, or a guarantee. Compare what each quote includes, not just the total at the bottom.
The Honest Bottom Line
A cheaper quote isn't always a worse deal — but a cheaper number with less inside it usually is. The fair comparison isn't "expensive roofer versus cheap roofer." It's "what's actually included versus what isn't."
Our customer in this story went ahead once he could see that, and his roof was sorted properly, once, with a guarantee behind it. If you're weighing up two quotes and one doesn't quite add up, we're glad to take a look and explain yours in plain English — no pressure, no jargon.
