After checking inside, it’s time to go out and verify how the roof looks like from an exterior viewpoint. One should look for obvious damage first: missing shingles, cracked tiles, warped or gapping wood shakes, and the like. Also, homeowners should check if the roof line is perfectly horizontal. This can be done by following the roof line with the eyes; if there is a noticeable sag in the line, it is a clear indication of a structural problem created by an untreated roof leak. Calling a professional once the sag is detected is highly recommended.
A homeowner must take note of the roof’s composition, as well. Determining whether professional re-roofing in Palo Alto is necessary will depend on the roofing material, as well as the immediate locale.
