What to Check Before Hiring a Roofer in Ireland
A roof is one of the most important parts of any building, and roofing work is expensive, weather-dependent and hard for most homeowners to check once it is finished. Choosing the right roofing contractor in Ireland is therefore just as important as choosing the right materials. A good roofer will diagnose the problem accurately, quote clearly, work safely and stand behind the job. A poor choice can leave you with a roof that still leaks, a bill that keeps growing or work that has to be done again.
This article sets out the practical checks to make before hiring a roofer: experience, insurance, written quotes, materials, guarantees, references and the warning signs of a contractor to avoid. It applies whether you need a small repair, a new flat roof on an extension or a complete re-roof.
Experience With Your Type of Roof
Roofing covers a wide range of work, from natural slate and concrete tiles to torch-on felt, fibreglass, liquid waterproofing, lead work, chimneys and guttering. A roofer who mainly installs new tiled roofs on housing estates may have less experience with a Victorian slate roof or a fibreglass dormer, and the reverse is also true.
Ask the roofer what type of work they do most often and whether they have recently worked on roofs similar to yours. An experienced roofer will be comfortable explaining how they would approach your roof, which materials they would use and why. Photographs of completed jobs on similar properties are a good sign.
Insurance and Safety
Roofing is high-risk work. Any roofer working on your property should hold public liability insurance, which covers damage to your property or injury to third parties during the work, and employers' liability insurance if they have staff. Ask for confirmation of insurance before work begins.
Safety on site matters too. A professional roofer will plan safe access using roof ladders, towers or scaffolding with edge protection, depending on the height and length of the job. Be wary of anyone who proposes to work on a two-storey roof from a single ladder without any other protection.
A Clear, Written Quote
A proper quote should be in writing and clear enough that you understand exactly what you are paying for. Look for:
- A description of the problem found during the inspection
- The work to be carried out, area by area
- The materials to be used, including brand or type where relevant
- Access equipment such as scaffolding and who provides it
- Removal and disposal of old materials and waste
- How hidden problems found during the work, such as rotten timbers, will be priced
- The expected start date and duration
- Payment terms and the total price including VAT
Getting two or three quotes for larger jobs is sensible. When comparing them, compare the content as well as the price. A much lower quote often leaves something out, such as underlay, insulation, lead work or waste removal.
Materials and Methods
The quality of materials has a direct effect on how long a roof lasts. Ask what slates, tiles, membranes, lead and fixings will be used, and why. For flat roofs, ask whether the system is torch-on felt, fibreglass or liquid waterproofing, how many layers will be applied and whether the deck will be replaced. For pitched roofs, ask about underlay, battens, ventilation and whether the ridge will be mortar bedded or fitted with a dry ridge system.
A good roofer will explain the options and the trade-offs honestly rather than pushing the most expensive choice. Our new roofs and flat roofs pages describe the materials and systems we use.
Guarantees and Aftercare
Ask what guarantee comes with the work and what it covers. There are usually two parts: the manufacturer's guarantee on materials and the roofer's own guarantee on workmanship. Make sure both are confirmed in writing, with the length of cover stated clearly. Ask what happens if a problem appears after the job is finished, and how quickly the roofer would return to look at it.
References and Reviews
Recommendations from people you know remain one of the best ways to find a reliable roofer. Online reviews are also useful, especially when they describe specific jobs and how problems were handled. A roofer with a long local track record has a reputation to protect and is usually easy to check.
It is reasonable to ask for contact details of previous customers or the addresses of recent jobs, so you can see the finished work for yourself.
Warning Signs to Watch For
Most roofers in Ireland are honest tradespeople, but there are some warning signs that should make you cautious:
- Unsolicited callers who knock on the door claiming to have spotted a problem with your roof
- Pressure to agree to the work on the spot or to pay a large deposit immediately
- A price given without any proper inspection of the roof
- No written quote, no business address and only a mobile number
- Requests for full payment in cash before the work starts
- Reluctance to confirm insurance or provide references
- Vague answers about materials and methods
If a contractor shows several of these signs, it is wise to get another opinion before agreeing to anything.
Regulations, Grants and Protected Buildings
Most roof repairs and like-for-like replacements do not need planning permission, but some work does. Changing the roof covering on a protected structure or in an architectural conservation area, altering the shape of the roof or adding dormers may require approval from the local authority. Work that adds insulation to a roof also has to meet Building Regulations on energy performance and ventilation. If you plan to apply for an energy upgrade grant, check the scheme rules before work begins, as some grants require specific contractors or approval in advance. An experienced roofer will flag these points early rather than leaving you to find out later.
Communication During the Job
Good communication is a sign of a professional contractor. The roofer should tell you when the work will start, how long it should take, what will happen if the weather turns and how the site will be kept safe and tidy. If something unexpected is found once the roof is opened, they should explain it, show you photographs and agree any extra cost with you before carrying out the work.
After the Work Is Finished
When the job is complete, ask for a short walk-through or a set of photographs showing what was done. Check that the site has been cleared, that gutters are free of debris and that any damaged plants or paving have been dealt with. Keep the invoice, guarantee and photographs together with your house documents. They are useful for insurance, for future maintenance and when you come to sell the property.
Choosing a roofing contractor comes down to experience with your type of roof, proper insurance, a clear written quote, good materials, a solid guarantee and a reputation you can check. Taking a little time over these points protects both your roof and your budget.
