When inspecting an asphalt shingle roof, what should the inspector comment on in the report?

When inspecting an asphalt shingle roof, commenting on the number of layers installed is particularly important due to its implications for the roof's performance and structural integrity. Multiple layers of shingles can affect the roof's ability to shed water, influence the effectiveness of roof ventilation, and contribute to potential overheating of the underlying structures.

In addition, some local building codes may only allow a certain number of layers for safety and effectiveness, so noting the number installed can inform future maintenance needs or potential issues with compliance. This information is essential for homeowners or buyers to understand the condition and expected lifespan of the roof, as well as any necessary repairs or replacements that may be required in the near future.

Other attributes mentioned, such as the color of the shingles, the age of the roof, and the brand used, while they may be relevant, do not carry the same weight in terms of structural performance and safety as the number of layers installed. Thus, the number of layers becomes a critical factor in assessing the overall condition of the asphalt shingle roof.
