There are thousands of slate roofs throughout our region. Many of these roofs are unnecessarily replaced each year. There are many slate roofs that do need to be replaced and are beyond serviceable condition, but there are many more with minor leaks and problems that can be fixed.

How to Repair a Slate Roof

by David Robinson

One of the unique features of a slate roof is that a slate roof is easily repairable. A slate roof is made up of thousands of individual pieces of natural slate. The combination of individual pieces of slate and separate flashing components allow repairs to be made in localized areas without replacing the entire roof.

Individual pieces of slate or areas of damaged slate can be replaced since the slates are not connected in anyway to the slates around them.This unique feature of slate roofs makes it important not to use roof cement or tar (not to mention caulk) to repair slate roofs.
