A professional roofer protects your home from the elements — the most important job in any property. Roofing covers everything from minor repairs and emergency leak fixes to full roof replacements, lead flashing and chimney work. Ask your roofer to confirm their current public liability insurance and any working-at-height / scaffolding competence (such as IPAF, PASMA or CSCS) the job calls for, and check the relevant register directly before any work begins or any money is paid.

Frequently asked questions
How do I know if my roof needs replacing or just repairing?
If your roof is under 20 years old and only a small number of tiles are damaged, repair is usually the right answer. If it is over 25–30 years old, has widespread issues, missing felt, significant moss growth or recurring leaks, a full replacement is often more cost-effective long-term. A good roofer will give an honest assessment — be wary of anyone who immediately recommends a full replacement without first inspecting properly.
Do I need scaffolding for roof work?
For safety and legal reasons, almost all roof work above single storey requires scaffolding. Any contractor who says they will work from ladders alone on a two-storey property should be avoided. Scaffolding adds cost but is non-negotiable for safe working at height. It should be included in your quote.
What is the difference between felt, EPDM and GRP flat roofing?
Traditional felt is the cheapest option (10–15 year lifespan). EPDM (rubber) is more durable (20–25 years) and excellent in the wet NI climate. GRP (fibreglass) is the most durable (25+ years) and seamless. For NI's high rainfall, EPDM or GRP are the better long-term investments.
How long does a new roof last?
Clay and concrete tiles last 50–100 years. Natural slate can last 80–150 years. Concrete interlocking tiles last 30–50 years. Flat roofing lifespan depends on material: felt 10–15 years, EPDM 20–25 years, GRP 25+ years. Proper maintenance and annual inspection significantly extends roof life.
Important
Always get a written guarantee covering both materials and workmanship before any roof work starts. Reputable roofers provide at least a 10-year guarantee on new roof installations. Never pay the full amount upfront.
