Modern roof maintenance depends on up to date techniques

Abstract
The use of contour maps is not at all complicated. The mositure contours graphically displayed on a contour map indicate the location and the degree of roof deterioration. Because roof deterioration and moisture penetration are closely related, it is possible to determine the amount of moisture present in a roof using the maps.
