Tile Roof Inspection Checklist

A thorough tile roof inspection helps protect a home from leaks, structural damage, and costly repairs. This checklist provides a practical, step-by-step guide for homeowners and professionals to assess clay, concrete, and slate tile roofs. It covers exterior and interior checks, safety considerations, common issues by tile type, and maintenance reminders to extend roof life and preserve curb appeal.

Pre-Inspection Preparation

Before climbing onto a roof, gather the right tools and plan for weather conditions. Use a sturdy ladder, fall-arrest equipment if needed, a digital camera, a flashlight, a pry bar, and a moisture meter for suspected leaks. Review the home’s roof layout, note roof penetrations such as vents and chimneys, and identify areas with prior repairs. Schedule the inspection after a dry spell and avoid inspecting during windy or icy conditions to prevent slips and misreads.

Exterior Visual Inspection

Assess the overall roof surface from ground level and, if safely possible, from an accessible ladder. Look for missing, cracked, or chipped tiles, broken fasteners, and displaced edges. Inspect flashing around chimneys, skylights, vents, and transitions to walls. Check for granule loss on asphalt-backed tiles and signs of curling or cupping in ceramic tiles. Pay attention to vegetation growth, moss, or debris buildup that can trap moisture and accelerate deterioration.

Tile-Specific Warning Signs

Clay and concrete tiles have different failure modes. Clay tiles may crack, crack lines can propagate underlayer damage, and hollow sounds indicate broken tiles. Concrete tiles are heavier and can crack under impact or freeze-thaw cycles; look for spalling, delamination, and sagging where fasteners may have failed. Slate tiles, while durable, can delaminate or crack from hard impacts or improper installation. Document any misaligned rows or tile spacing issues that could allow water intrusion.

Interior Inspection and Attic Survey

Inspect the attic for signs of moisture, mildew, or staining around roof penetrations and along rafters. Look for damp insulation, dark spots, and water staining on underside of sheathing. Check for frost damage or temperature inconsistencies that may indicate leaks. If accessible, examine flashing details from the attic side and ensure there is proper ventilation to prevent condensation that mimics leaks.

Water intrusion Indicators

Key indicators include damp or stained ceiling areas, musty odors, and mold growth. Track the source by inspecting interior walls and ceilings near suspected leak zones and comparing with exterior observations. A moisture meter can confirm elevated readings behind walls or under insulation. For ongoing leaks, identify seasonal patterns such as after heavy rain or freeze-thaw cycles, which help target repair priorities.

Safety Considerations

Tile roofs can be slippery and fragile. Use non-slip footwear, a harness when working on steep pitches, and a helper for ladder stability. Avoid walking on tiles that appear cracked or loose. Do not step on ridges or near edges where tiles may be stressed. When in doubt, contact a licensed roofing professional to perform the inspection or repairs to prevent personal injury and further roof damage.

Common Issues by Tile Type

Different tile materials exhibit distinct failure patterns. The table below highlights typical problems and recommended actions for clay, concrete, and slate tiles.

Tile Type	Common Issues	Recommended Action
Clay	Cracking, chipping, edge spalling	Replace broken tiles, reseat loose tiles, inspect underlayment
Concrete	Cracking, spalling, heavy tiles	Check fasteners, replace cracked tiles, evaluate underlayment integrity
Slate	Cracking, delamination, slipping	Replace damaged slates, confirm secure mounts, inspect racking system

Repair Prioritization and Documentation

Document findings with photos and notes, noting exact tile locations and measurements. Prioritize issues that affect watertight integrity, such as missing tiles, damaged flashing, or compromised underlayment. Create a repair plan with short-, medium-, and long-term tasks. Maintain a record of all inspections to track deterioration and inform future maintenance needs.

Maintenance Tips and Frequency

Perform a basic exterior visual check after severe weather and at least twice a year. Clean debris from gutters and eaves to prevent moisture buildup near the roofline. Schedule professional inspections every 3–5 years or after major hail events or storms. Address minor issues promptly to extend tile life and prevent escalating damage.

Professional Help: When to Hire a Roofer

Consider a licensed roofer for complex assessments, structural concerns, or extensive damage. Hire a professional if tiles are missing, the underlayment is suspected to be compromised, or flashing shows signs of corrosion or improper installation. Obtain multiple quotes, verify credentials, and request a detailed written report outlining recommended repairs and warranties.

Additional Resources and Tools

Use digital tools and guides from manufacturer specifications, local building codes, and roofing associations for reference values and best practices. Consider using drone imaging for hard-to-reach roof sections and a moisture meter for precise leak detection. Keep an updated inventory of tile types and replacement parts to streamline future maintenance.
