Causes and Types of Slate Roof Repairs

Broken or Missing Slate Tiles

Slate tiles can crack, chip, or break due to impacts or aging. Replacing damaged tiles promptly ensures the integrity of the roof and prevents water infiltration.

Loose or Sliding Tiles

Over time, slate roof tiles may loosen or slide out of place, compromising the roof’s ability to shed water effectively. Reattaching these tiles is crucial for maintaining a watertight roof.

Crumbling or Delaminating Slate

Crumbling slate may result from poor-quality material or exposure to harsh elements causing delamination. This compromises the roof’s integrity. Replace damaged slates with high-quality replacements.

Weathered or Fading Slate

Some slate roofs may exhibit weathering or fading over time. Roofers can restore the slate’s appearance by cleaning, sealing, or applying specialized treatments.

Leaks and Water Infiltration

Leaks in a slate roof can be caused by damaged or misplaced tiles, deteriorated flashing, or gaps in the roof structure. Identifying the source of leaks and addressing them promptly prevents interior water damage.

The Slate Roof Repairs Process

Assessment and Inspection

A thorough assessment of the roof’s condition will be done first before repairs are made. Our roofers will carefully inspect the entire surface for cracked, chipped, or missing slates. They’ll also check for signs of water damage, such as leaks or stains on the ceiling. The condition of the underlying structure will be noted, including the roof deck and flashing.

Gathering Materials and Tools

To execute slate roof repairs effectively, we’ll use specific roofing materials and tools. Things like replacement slates, copper or stainless steel nails, a slate ripper, a hammer, a ladder, a safety harness, and protective gear will be utilized. Quality materials are key to long-lasting repair, so we invest in high-grade slates that match your existing roof.

Safety Precautions

Safety is paramount to all of our roofing projects. We use secure ladders, safety harnesses, and protective gear to prevent accidents. If the repair project seems daunting, our professional roofers are equipped to handle the task efficiently and safely.

Slate Removal

Using advanced slate ripper tools, our skilled contractors carefully remove damaged or loose slates. We work systematically from the bottom up to minimize the risk of additional damage. Our focus is on preserving the existing slate arrangement for a seamless repair.

Inspecting the Underlayment

Once slate shingles are removed, our experts inspect the underlayment and flashing for any issues. We replace or repair damaged underlayment to ensure a watertight seal, safeguarding the structural integrity of the roof.

Slate Replacement

At Thunder Bay Roofing, we understand the importance of slate selection. Our professionals meticulously choose replacement slates that match in size, thickness, and color, ensuring a harmonious blend with the existing roof. Each slate is securely fastened with copper or stainless steel nails to prevent future issues.


Our roofers pay attention to detail when repointing mortar joints between slates. The use of a suitable mortar mix ensures a durable bond and optimal weather resistance, contributing to the long-term resilience of your slate roof.

Flashing Inspection and Repair

We conduct a thorough examination of flashing around chimneys, vents, and valleys, identifying any signs of damage or wear. Damaged flashing is promptly replaced or repaired, preventing water infiltration and preserving the overall integrity of the roof.

​Regular Maintenance

Following repairs, Thunder Bay Roofing recommends establishing a routine maintenance schedule. Our team encourages homeowners to schedule annual inspections to address any emerging issues promptly, extending the lifespan of their slate roofs.
