roof slate pricesIn case your slate roof is damaged or leaking, perhaps you’ll notice that replacing roof slates resolves the problem. You’ll notice that roof slate cost is more expensive than other roofing materials; however since they’re extremely hard-wearing and long lasting, they will probably outlast alternatives such as clay tiles.

British Slate

Watertight, long-lasting, and hardwearing —slate produced domestically survives many conditions on our roofs. The launch of BS EN 123261 in 2004 guarantees that the newly produced British slate is fire-breathing and frost-proof.

Britain produces many slates, but the one accepted as the best worldwide is the grey-blue Welsh slate. Reputable slates identified with Britain include the Scottish Ballachulish and Easdale slates, the dark-grey Cornish Delabole slate, the green Westmorland, and Burlington blue-grey slates from the Lake District. Numerous kinds of stone provide a solid choice.

There is, however, a price to pay for these highly durable slates. Not just on the material, but fixing a natural slate roof consumes a lot of time, requires good skills, and should, therefore, be considered when drawing up your budget. In the case of re-slating an old roof, tell your roofer to save as many existing slates as he can.

Pair natural slates similar to the preserved slates in terms of hue, texture, and size, and re-lay them in a random array to produce a distinctive roof. Also, you can take the slates to a reclamation yard. There is a high demand for reclaimed slates of good quality, which is both sustainable and economical.

Imported Slates

Spain alone provides about 75% of the slates used globally, making her the largest exporter of slates. One of the cheapest natural slates on the market is the Chinese slate. Imported slate is ubiquitous and in high demand because it provides competitive prices and various hues.

The Canadian slate can be used in place of the Welsh slate.

Although imported slate has been a victim of bad press, you can actually buy them without regret if you do proper research. Request for samples and make sure that the products are tested to BS EN123261. Under this standard, water absorption is tested(the lower the water absorption rate, the higher the durability). High carbonate content of 20% and above in slates may lead to rapid discoloration. If you are particularly bothered about changing appearance, demand for a written statement from your manufacturer which will be in alongside the standard guarantee (a period of 30 years at least)

Once the product is delivered to you, pick out a random sample and test it. If you tap the slate and it gives a clear ring, it is of good quality, but if it gives a dull thud, it is of inferior quality and should be rejected.

Man-made Alternatives

Although artificial slates are widely used due to their affordability, they do not have the beauty and durability of natural slates. The consistency of their color, shape, texture, and size during production gives them an unvarying and fashionable finish. Consistency also indicates that they don’t have to be laid in a double-lapping bond to provide watertight protection like their natural counterparts. They are laid in a single bond, and the ease of pre-drilled holes make it very easy to install, therefore saving money and time.

Other possible alternatives are the Concrete slates and slates produced from rejuvenated slate dust. Fiber-cement slates produced from cement, mineral additives, and organic fibers are perfect for complex designs, vertical roof pitches, or roofs in need of a lightweight solution. (copper rivets are normally needed to hold the light material in place). However, the base color of fiber-cement and concrete slates may be exposed to the elements as time passes which is not the case for natural slates.

The increasing demand for slates has led to the introduction of Clay-based slates, which offers great sturdiness against weathering.

Roofing Slates Prices

Roofing slate prices differ based on the type of slate you choose; some are of superior quality to others. For instance, imported slate roofing from Spain is more expensive. Synthetic slate roof tiles prices or second-generation tiles manufactured from a mix of different slates are more affordable options; slates bought in bulk can also save a few bucks in the long run.
