Slate Roofs
Expert Slate Roofing Services in Fife and Edinburgh by LC Joinery Scotland
Slate roofs have been a tradition in Scotland since the mid-16th century, tailored to endure the harsh Scottish winters. Scottish slates, thicker and sturdier than those used elsewhere, are typically nailed in 'diminishing courses,' with smaller slates at the top and larger ones lower down. While slate roofs are more expensive than tiled roofs, they last significantly longer, making them a worthwhile investment.
Maintenance and Repair
Slate roofs are renowned for their durability, often lasting over 100 years. However, maintenance and timely repairs are crucial. Slates can slip or break due to corrosion of the fixings, known as nail sickness, especially if poor-quality nails were used. This can lead to water penetration, causing further damage.
​
​Additionally, decades of movement can enlarge nail holes, causing slates to loosen. High winds can cause slates to rub together, leading to cracks or breaks. Amateur repairs using silicon or mastic can create blockages, trapping water and causing leaks. Proper professional repairs ensure water flows away harmlessly, preventing damage.
Professional Roofing Repairs in Fife and Edinburgh
When initially installing slate roofs, builders work from the bottom up, nailing each slate to wooden sarking or battens. Replacing slates on an existing roof requires using lead or copper clips (tingles) since the original nails are inaccessible. A narrow lead or copper strip is nailed to the batten, the slate is slid into place, and the strip is bent up under the slate to secure it.

​We recommend using copper slate nails for added durability. Our services include forming traditional lead valleys, fitting zinc ridges, and performing any required lead work.
