Proper roof installation is, of course, one of the most critical aspects of building construction. A well-constructed roof assures the longevity of the structure, as well as the comfort of the structure’s occupants. It is also the most exposed aspect of any building, and competent roofers are aware of the construction techniques and materials necessary for a roof to stand up to weather and abuse. Part of any roofing project involves the implication that frequent and competent roof inspections will be undertaken on a regular basis.
Some common problems addressed in a roof inspection are blistering due to trapped water vapor, open laps around flashing due to poor adhesion of membrane to metal flashing, splitting of roof surface material, deteriorating or loose flashing, and fastener issues. Older roofs are inspected for brittleness and surface deterioration, while newer roofs are notable for showing settlement problems that are easily corrected. Crumbling chimneys and loose or defective gutters are also included in the issues to be addressed in a roof inspection.
