Most homeowners would rather do inexpensive repairs than a very expensive slate roof replacement. Making recommendations can be a slippery slope for a roof contractor.

Different Types and Styles of Slate Roofing Tiles?
- Standard (uniform) slate – The most common slate installation consists of pieces of uniformly-cut slate. The slate is arranged like asphalt shingles, which enables easier repairs.
- Patterned slate – Slates of different shapes and colors can be presented into the standard slate installation method, which can be used to create different patterns that can be noticed from a curbside view.
Textural slate – Uses rough-textured slate varying in thickness and size, ensuing in a rough appearance.
What Constitutes a High Quality Slate Roof Installation?
- Check the angle / pitch of your roof, depending on how steep or shallow your roof is; this will dictate how much overlap or head lap is required on your slates.
- Make sure that the wood underneath is cleared of old nails and splinters that may damage the integrity of the roof.
- Roll out the chosen underlayment which will add another layer of protection from severe weather from your home.
- Secure the underlayment with preferably copper or galvanized nails firmly into position but not too hard that the underlayment is damaged or ripped.
- Mark reference points are level while laying the slate tiles.
- One of the most important things with slate tiles is to use copper nails when installing. This is because standard metal nails will rust and fall apart after 40-50 years and the slate ties will start to loosen up and fall off the roof one by one. In fact, our number one service call with slate roofs is re-securing the tiles where the roof was not done with copper nails.
- When securing the slate, make sure the nails do not penetrate through and out the other side and puncture the underlayment which will cause water to seep into your attic space.
- Install proper drip edge and ensure that all roofing penetrations are properly flashed and sealed. Drip edges should be installed to prevent water from being blown up under your slate tiles.
