every structure has a roof.
evaluate. specify. repair.
We know roofs.
Wallace’s roof assessment and inspection team is experienced with standing seam, TPO, PVC, EPDM, ModBit, BUR and screw down metal roof systems. We have developed an assessment process that identifies when the condition of a roof justifies repair or replacement. In addition, most of our roof consultants are licensed professional engineers and can rapidly develop re-roof and structural repair drawings as required. Our mission is to extend the lifespan of your roof, specify repairs when needed and recommend replacement when necessary.

assess
damage and create solutions.
Our evaluation process includes general condition, damage, life-cycle, and installation assessments.
Our assessment scorecard is a numerical roof condition grading system saved in our database to help facility managers prioritize, schedule and budget future maintenance planning.
We are able to recommend and design repairs as well as provide re-roof design drawings along with the calculations for code and energy verifications.
