Traditional Cut Roofing and Slating

The biggest drawback of slate roofing is the weight. Natural slate is significantly heavier than concrete or clay tiles, so the roof structure needs to be strong enough – or reinforced – to carry the load, which can add cost to a project. Slate can also be brittle, so it needs to be handled with care and fitted correctly during traditional cut roofing work to avoid cracked or chipped tiles.

Installation also calls for a genuinely skilled slater, as poor workmanship shortens a roof’s lifespan considerably. Working with an experienced traditional cut roofing specialist from the outset, like Peninsula Custom Construction LTD, will avoid these problems. You can see examples of our work on our projects page.

Traditionally, slates are cut and dressed by hand using a slater’s hammer and cutting iron (or zax), which allows precise shaping around chimneys, valleys and verges – the hallmark of genuine traditional cut roofing. Holes for fixing nails are then punched at the correct angle so each slate hangs securely without cracking.

While slate cutters and guillotines are sometimes used for speed on larger jobs, hand-cutting remains the preferred method for bespoke detailing on period and listed properties, since it gives far greater control.

As expert tradespeople of slate cut roofing we understand how important adhering and mastering the roofing process, when done properly traditional cut slate roofing will can last up to, and beyond, 100 years. It’s a low maintenance, value adding option that is the cherry on the icing of most heritage properties.

A well-installed natural slate roof is one of the longest-lasting roofing options available, typically lasting 80-100 years, in many cases this is extended to well over a century. This is a key reason slate roofing remains popular outside of its beauty and sustainability. Although it can sometimes cost more up-front, the lower cost of maintenance and long lifespan can often far outweigh that initial cost.

Many historic slate roofs were originally laid without any underlay at all, relying purely on the tight lap of the slates to keep out the weather. However, current best practice – and Building Regulations on most re-roofing work – call for a breathable roofing membrane beneath the slates to provide an extra layer of protection against wind and rain and to improve insulation performance.

Get in touch with our team and we’ll help you to match the ideal membrane and slate to your roof. We’ve also established relationships with suppliers around Devon and Cornwall meaning we can often source materials quicker than other roofers.

Some people use WD-40 or similar products to temporarily darken faded slate and give it a ‘wet look’ sheen, but this is a short-term, cosmetic fix rather than a genuine repair and it fades over time. It can also leave the surface slippery and attract other types of dirt.

If your slate roof is looking tired, worn or is leaking or in need of a refresh, having it properly assessed will give you peace of mind. Get in touch with our team and we’ll let you know whether you need a clean, repair or re-roof as the best option.
