Is lead still king of the roof? 🏠

Living in North Wales, we know how much punishment a roof takes from the wind and rain. When it comes to flashing, you have two main choices: traditional lead or modern synthetic alternatives.

Lead offers unmatched longevity (60-100 years) and that classic heritage look perfect for Snowdonia cottages. Modern alternatives are lighter, have no scrap value for thieves, and are great for quick repairs on newer builds.

We’ve taken a deep dive into which material is right for your property on our latest blog. Click the link in our bio to read the full guide!

Lead flashing vs alternatives: which is right for your roof? At Sion Owens Roofing Limited, we believe in providing honest, practical advice to homeowners across North Wales. While lead is the traditional choice for heritage properties in Bethesda and surrounding areas due to its 60+ year lifespan, modern synthetic alternatives offer great benefits for specific projects, such as being lightweight and having no scrap value to deter theft. Our latest blog post explains the differences in durability, cost, and installation to help you decide which material will best protect your home from the Welsh weather. As a CHAS accredited firm, we provide expert installation for both lead and modern systems, backed by a workmanship guarantee of up to 20 years. Call us for a free quote.

Moss on a roof is a common sight in Gwynedd, Conwy, and Anglesey, but it can lead to problems if left unchecked. Thick moss holds water, which causes damage to slates during frosty nights and leads to blocked gutters. Our team at Sion Owens Roofing, based in Bethesda, provides professional roof moss removal and maintenance services. We use manual, sensitive techniques to clear your roof without the risks associated with high-pressure washing. Protect your home and ensure your Welsh slate lasts for generations.
