We understand that your roof is one of the most important parts of your home. That’s why every project is completed with attention to detail, honest advice and workmanship we’re proud to stand behind. From replacing slipped roof tiles after heavy winds to installing an entirely new slate or tiled roof, we offer reliable roofing solutions throughout Flintshire.
As a local roofing company, we regularly work in Flint, Mold, Holywell, Buckley, Connah’s Quay, Hawarden, Queensferry, Northop, Shotton and the surrounding areas, providing homeowners with dependable roofing services and free, no-obligation quotations.
If your existing roof has reached the end of its lifespan, we can install a brand-new tiled or slate roof that improves both the appearance and protection of your property. Every new roof is built to current British Standards using quality materials designed for decades of performance.
A damaged roof can quickly lead to water ingress, damp and expensive structural problems if left untreated. Our experienced team carries out reliable repairs for slipped or broken roof tiles, missing ridge tiles, storm damage, roof leaks, damaged lead flashing, chimney issues, valley repairs and general roof maintenance to help keep your property safe, dry and protected.
We replace ageing timber rooflines with low-maintenance uPVC fascias, soffits, guttering and cladding, helping protect your property from water damage while giving your home a cleaner, modern appearance.
Your roof protects everything underneath it, so it’s important to choose contractors who take pride in doing the job properly.
Whether we’re replacing a single ridge tile or installing a completely new pitched roof, we approach every project with the same attention to detail. We don’t believe in cutting corners or recommending unnecessary work—our reputation is built on honest advice, quality workmanship and long-lasting roofing solutions.
Our aim is simple: provide Flintshire homeowners with roofing work we’d be happy to have on our own homes.
Choosing the right roofing contractor is important, especially as many homeowners may only repair or replace a roof once in their lifetime. At Onyx Roofing, we aim to make the entire process straightforward from the initial quotation through to completion, with honest advice without pressure selling, high-quality workmanship, premium roofing materials, reliable and tidy service, and competitive pricing. We treat every property with respect and complete every job to the highest standard possible.

We put out an enquiry as we had been badly let down by a previous roofer. James contacted us and came that day. He was charming, knowledgeable and reassuring. He started within two days, his work was exemplary - with a great attention to detail - and great value for money. James noticed a few little niggly problems and went above and beyond to fix those too. Wish we had contacted him first. Would thoroughly recommend him.Posted on Google![]()
