Roof Slating In Cornwall
Natural and artificial slate installations provide unmatched longevity for pitched roofs across Cornwall, combining traditional craftsmanship with modern fixing methods. Our roofing contractors work with premium grade materials sourced from established quarries worldwide, creating weather-resistant roof coverings that protect properties for generations.
Natural Slate Varieties
Welsh slate remains the gold standard for roofing projects, offering distinctive blue-grey colouring and exceptional durability that has proven itself over centuries.
Spanish slate provides cost-effective alternatives with varied colour options including grey, black and green tones that complement different architectural styles. Burlington slate from Cumbria delivers consistent quality with uniform thickness and reliable weather performance.
We source only the finest grades that meet European standards BS EN 12326-1/2, guaranteeing consistent quality and performance. Each slate batch undergoes rigorous testing for water absorption, thermal cycling and freeze-thaw resistance before installation.
Slate Grading & Selection
We classify slates according to their geological composition and expected lifespan. T1 graded slates provide the longest service life, typically exceeding 100 years with minimal maintenance requirements. S1 classification indicates slates suitable for severe exposure conditions, perfect for Cornwall's coastal environments where wind-driven rain and salt air challenge roofing materials.
Thickness specifications range from 4mm for lightweight applications to 10mm for areas requiring maximum resistance. We match slate selection to your property's exposure conditions, architectural requirements and budget considerations.
Artificial Slate
Modern fibre cement slates replicate natural slate appearance whilst offering consistent dimensions and reduced weight loads on roof structures. These manufactured products resist moss growth, colour fading and frost damage that can affect natural materials over time. Installation is typically faster due to uniform sizing and pre-drilled nail holes.
Artificial slates incorporate recycled materials in their production, supporting environmental sustainability whilst delivering generous manufacturer warranties. The reduced weight allows installation on roof structures that cannot support natural slate loads, extending design possibilities for extensions and conversions.
Traditional Roof Slate Installation
Double-lap slating techniques provide maximum weather protection by creating two layers of slate coverage across the entire roof surface.
We calculate lap dimensions based on roof pitch, exposure conditions and slate length to prevent wind-driven rain penetration. Copper nails and clips resist corrosion in marine environments, maintaining fixing integrity throughout the slate's service life.
Head nailing secures slates at their thickest point, distributing wind loads effectively across the roof structure. Centre nailing suits lower pitches where wind uplift requires additional security. We select fixing methods based on your roof's specific exposure conditions and slate characteristics.
Batten Specifications
Treated softwood battens provide secure fixing points whilst accommodating slight irregularities in roof timber alignment. Gauge measurements determine batten spacing to achieve correct slate overlap and weather performance. We check batten alignment carefully during installation to prevent slate slippage and maintain straight courses.
Counter-batten installations improve ventilation beneath slates whilst creating level fixing surfaces on irregular roof timbers. This technique proves particularly valuable when re-slating older properties where roof timbers may have moved or settled over time.
Roof Slate Repairs
Individual slate replacement addresses storm damage, thermal shock failures and general wear without disturbing surrounding areas of the roofing system.
We match replacement slates carefully to existing materials, considering colour variation and weathering patterns developed over time. Hook and tingle repairs provide temporary solutions until complete re-slating becomes necessary.
Ridge tile maintenance prevents water penetration at roof apex areas where wind uplift and thermal movement create demanding conditions. We renew pointing materials regularly and replace cracked tiles before they compromise the roof's waterproof integrity.
