Our Roof Evaluation Process
Having your roof evaluated by a professional is the first step to understanding whether your roof needs a simple roof repair or a roof replacement. Our estimator walks you through every step of the process while explaining exactly what he sees. Our goal is to give you the information you need to make the best choice for your home and your budget.

External Inspection
Our roof evaluation begins with a visual inspection of the exterior roofing system. We look for common signs of wear such as missing shingles, bent or lifting shingles, and granule loss that can reduce your roof’s ability to protect your home. This step helps identify surface-level issues and determine whether repairs, maintenance, or further evaluation may be needed..
Internal Inspection
The interior evaluation focuses on inspecting the attic and accessible crawl space areas to identify signs of moisture intrusion or structural concerns. This includes checking for water staining, damp insulation, mold indicators, and proper ventilation. Evaluating these areas helps determine whether issues on the roof surface have affected the underlying structure and allows for a more complete understanding of your roof’s overall condition.

Once the evaluation is complete, we walk you through the condition of your roof and explain what the findings mean for your home. We review potential repair or replacement options, discuss material considerations, and answer questions about how different roofing systems. We provide all of this information in writing.
