Shingle Roofing Inspection Checklist

Regular roof inspection and maintenance are essential to reduce roof repair services. Sometimes you may need to perform roof inspections on your own. Find below the items you should have on your shingle roofing inspection checklist.

Loss of Roof Granules

Granule loss indicates the disintegration of your shingle roofing. Asphalt shingles consist of a protective layer of granules. Over time the granules weather, leaving an exposed surface. Common causes of shingles granule loss include hailstones, roof traffic, old age, and blisters due to manufacturing defects.

The shingle roof leaks once the granular loss damage exposes the surface. Bald patches on your asphalt shingles indicate that it's time for you to replace your shingle roofing materials.

Curled, Flapping, Missing, and Broken Shingles

Curling shingles entail turned-up shingle edges with sunken middle parts, forming a concave shape. This defect indicates aging roof materials. The shingles become brittle and can easily break. Flapping shingles are a result of strong winds. Loose nails cause this defect. For example, when strong winds blow, the shingles flap and then get back to their position.

You'll find it difficult to identify flapping shingles because they are still in place. However, with time, the shingles might break out of place. This results in missing shingles which are easier to spot on your roof. Continuous flapping may also result in broken shingles because of the impact when the shingles fall back after the winds.

All the above defects call for the urgent need for roof repair services. You will need to fasten the nails to prevent flapping that leads to broken and missing shingles. Replace curled-up shingles with new ones. If you notice many curled-up shingles, you will have to replace the entire roof.

Moss and Mold Infestation

Moss and mold grow on roof shingles due to damp conditions. This condition is common in humid regions. Shade cast by trees on your roof also causes roof dampening. Lastly, continuous moist conditions favor moss, mold, and mildew growth on the roof shingles.

The mold and moss retain moisture, and after some time, the roofing materials start to rot. You should, therefore, check for any mold and moss and clear them to eliminate excess moisture. Extensive mold growth will force you to contact roof repair services for your roof repair or replacement.

Sagging Roofing

A sagging roofline calls for immediate roof repair and further professional inspection. The professional will determine the possible causes and remedies. When the case is severe, a sagging roof may damage the entire house. The sagging will cause uneven roof load distribution, which might overwhelm some walls and lead to their collapse. The earlier you respond to this issue, the better chances for saving your entire house from collapse.


You have to be cautious when you undertake roof inspections on your own. Only attempt it if you ensure your safety. If you are uncomfortable, seek help from a roofing contractor who provides roof repair services. Such professionals will repair or replace your roof as needed.
