Roof Inspection Checklist

This checklist provides a thorough guide for inspecting an existing roof to identify potential issues such as leaks, material degradation, drainage problems, and structural concerns. By following this checklist, roofing professionals can assess the condition of the roof and recommend necessary repairs or maintenance to prolong its lifespan.

Check for visible signs of roof sagging or uneven areas

Inspect for any standing water or ponding, especially on flat roofs

Verify that the roof slope is adequate for proper drainage

Look for signs of leaks or water damage on ceilings and interior walls

Check for mold, mildew, or algae growth on the roof surface

Inspect shingles, tiles, or metal panels for cracks, curling, warping, or missing pieces

Check for granule loss on asphalt shingles, which may indicate aging

Examine seams and joints for separation or deterioration

Look for punctures, blisters, or bubbles in roofing membranes

Inspect for loose, rusted, or corroded fasteners and nails

Ensure that all flashing (chimneys, vents, skylights, etc.) is properly sealed and intact

Check for cracks or gaps in sealants and caulking around flashing and roof penetrations

Verify that counter-flashing is properly secured and in good condition

Inspect metal flashings for rust, dents, or signs of lifting

Clear debris from gutters and downspouts to ensure proper water flow

Check for sagging, loose, or damaged gutters

Inspect for water stains or signs of overflow near eaves and fascia boards

Ensure that downspouts direct water away from the foundation and are not clogged

Look for signs of ice dams or improper drainage in colder climates

Inspect vents, skylights, chimneys, and HVAC units for proper sealing and flashing

Check for debris or blockages in ridge vents, soffit vents, and attic ventilation systems

Ensure attic ventilation is sufficient to prevent condensation and heat buildup

Verify that pipe boots and vent stacks are properly sealed and not cracked or deteriorated

Look for any signs of rot or damage in roof decking and structural components

Check for loose or damaged fascia and soffit boards

Inspect attic for signs of leaks, moisture buildup, or structural weakening

Ensure that all roofing components are securely fastened and not at risk of wind uplift

Verify presence and security of fall protection and harness points
