Slate Roofing Inspection Services We Provide

Your slate roof represents a significant investment that demands regular professional evaluation to maintain its century-long lifespan and elegant appearance. We provide thorough inspection services that examine every component of your natural stone roofing system to ensure optimal performance and longevity.

Complete Slate Tile Assessment

Our inspectors carefully examine each slate tile for cracks, chips, displacement, and signs of deterioration that could compromise your roof's waterproof integrity. We check the condition of individual tiles to determine if repairs or selective replacement will prevent water intrusion and extend your roof's lifespan.


During this assessment, we document the age and quality of your slate materials, which helps predict future maintenance needs for your property. This detailed tile evaluation provides you with a clear understanding of your roof's current condition and any immediate concerns requiring attention.

Flashing and Valley Inspection

Flashing around chimneys, skylights, and roof penetrations represents critical waterproofing points that we inspect thoroughly to prevent leaks and water damage to your home. We examine valley areas where two roof planes meet, as these locations experience increased water flow and require properly installed copper or lead-coated flashing.


Our team checks for rust, separation, improper installation, or deterioration in all flashing components that could allow water to penetrate beneath your slate tiles. Identifying flashing issues early prevents extensive interior damage and protects the structural integrity of your entire roofing system from costly water infiltration.

Structural Support Evaluation

Slate roofing weighs significantly more than standard asphalt shingles, which means your roof's structural support system must maintain adequate strength to carry this load. We inspect roof decking, rafters, and underlying support structures to ensure they can safely support your natural stone roofing materials without sagging or failure.


Our evaluation includes checking for signs of water damage, rot, or deterioration in the wooden components that support your premium slate tiles. This structural assessment protects your investment by confirming your roof's foundation remains strong enough to support slate for decades to come.

Fastener and Attachment Review

Proper fastening keeps slate tiles securely attached to your roof through high winds, earthquakes, and severe weather conditions common in southern California. We inspect all fasteners, hooks, and attachment points to ensure they remain corrosion-free and properly secured to prevent tiles from slipping or falling.


Our team checks that copper or stainless steel fasteners are used, as these materials resist corrosion and last as long as the slate itself. Identifying loose or corroded fasteners during inspection prevents tile loss during storms and protects people and property below from falling slate debris.

Our Slate Roofing Inspection Services Process

Understanding what happens during a professional slate roof inspection helps you prepare for the evaluation and know what to expect from our thorough assessment. Our systematic approach ensures no component of your premium roofing system goes unexamined, providing you with complete information about your roof's current condition.

Initial Exterior Assessment


We begin with a comprehensive ground-level evaluation of your entire roof, using binoculars to examine visible areas and identify obvious concerns before climbing up. This initial assessment includes photographing your roof from multiple angles to document its current condition and provide a before-and-after comparison for future inspections.


Detailed Roof-Level Examination


Our certified inspectors carefully walk your slate roof using proper techniques that prevent damage to tiles while conducting a thorough hands-on inspection of materials. We examine individual tiles, checking for cracks, chips, loose fasteners, and signs of deterioration that could compromise your roof's waterproof protection and longevity.


Interior Attic Inspection


Checking your attic space from inside reveals water stains, active leaks, inadequate ventilation, or structural issues not visible from the exterior roof surface. We examine roof decking from below to identify any sagging, rot, or water damage that indicates problems with your slate roof's performance. 

Why Choose Our Professional Slate Roofing Inspection Services

Attempting to inspect slate roofs without proper training risks damaging expensive tiles and missing critical issues that trained inspectors identify immediately during evaluations.

Our inspectors receive specific training in slate roofing systems, including knowledge of different slate grades, proper fastening techniques, and compatible flashing materials for this premium material.

Walking on slate roofs requires specialized equipment and techniques to prevent tile damage and ensure inspector safety on steep or high residential structures. We use professional-grade ladders, safety harnesses, roof jacks, and padded shoes designed specifically for slate roof work that protect both our team and your property.


Accurate Damage Assessment


Experienced inspectors distinguish between cosmetic issues and serious structural problems, helping you prioritize repairs and avoid unnecessary replacement of serviceable slate tiles. Our knowledge of slate roofing helps us identify whether cracked tiles result from normal aging, improper installation, or structural issues requiring different repair approaches.

Frequently Asked Questions

  • How often should I schedule slate roofing inspection services for my home?

    Property owners should arrange professional slate roof inspections every three to five years to catch potential issues before they become expensive problems. However, you should schedule an inspection immediately after severe storms, earthquakes, or if you notice any loose tiles or interior water stains.

    Our comprehensive inspection examines all slate tiles, flashing, fasteners, valleys, penetrations, and underlying roof structure to assess your system's complete condition.
