Present day technology allows select roof consulting firms to evaluate and predict, with a reasonable degree of scientific certainty, the condition and projected longevity of existing roof systems. Although maintenance is much less costly than roof replacement, it is more difficult to determine the causes of isolated roof problems. Moisture surveys provide the critical data to determine the origin and solution of problem areas.

A.R.T. moisture surveys include scale roof plan, areas of entrapped moisture, maintenance items, photo documentation and comprehensive written report with maintenance budgets. Moisture survey techniques include radioisotopic, infrared, capacitance and electronic.
