How does a roofing company repair a slate tile on a roof?

To repair a broken slate tile on a roof, a roofing company can use a variety of techniques. One technique involves sliding the slate to a point where the bottom of the slate is flush with the bottom of the slates on either side. Once positioned, the slate is attached using copper roofing nails. The first nail should be placed between the two slates directly above the repair slate, approximately 2 inches above the bottom of the slates.

Another technique involves using a slate hook to repair incidental damage. The head of the tool is worked up under the damaged piece until the tool’s hooked head catches a nail shank. Then, the handle of the tool is struck with a hammer to cut through the nail shank. When both shanks are severed, the damaged slate is slid out, being careful not to disturb adjacent pieces.

If the slate cannot be repaired, it may need to be replaced. To replace the slate, the broken slate is removed, and the size is measured. If the slate is nonexistent, the distance in between the slats is measured, and then two inches above the bond line is measured to ensure the water would come down onto a full tile. The new slate piece is then installed and secured with nails or adhesive.

Overall, the specific technique used by a roofing company to repair a slate tile on a roof will depend on the extent of the damage and the individual company's preferred methods.
