This job is a good example of regular maintenance on a slate or tile roof. You likely won’t know you have cracked slates until you have an experienced professional on the roof, looking things over up-close-and-personal. While 99% of this roof was in great shape, we did find a grand total of 40 broken slates throughout, so our repairs were timely and prevented costly leaks. These types of repairs make up the vast majority of our historic roof work- we prefer to care for your roof BEFORE you ever have a leak!
