Slate roof repair in Pittsburgh, PA. Individual slate replacement and flashing on Squirrel Hill, Shadyside, and North Side roofs. Call (412) 866-2986.
Slate roof repair in Pittsburgh is a specialty of older East End and North Side housing. A slipped or broken slate is not a reason to tear the roof off. It is a reason to pull the broken piece, hook a matching slate, and check the flashing around chimneys and valleys that actually started the leak.
Walking slate like asphalt destroys adjacent pieces. We use proper hooks and limit traffic. If the underlayment and nails are gone across a slope, we will say replacement is more honest than a hundred individual swaps.
Emergency tarping still applies when a section is open after a wind event. Permanent slate work waits on matching color and thickness.

Yes. Broken slates are removed and hung with a copper or stainless hook or a slate nail and bib. Done properly, the repair disappears into the field.
Usually the nails and flashings fail before the slate does. A roof full of sound slate can still leak everywhere because the fasteners have rusted through.
That is a budget and character decision, not a technical one. Sound slate can be maintained for decades, and asphalt over a slate-era house often looks wrong and does not last as long.
