Roof Leaks/Moisture: Did you know that a roof can have silent leaks for years before evidence presents itself? Most homeowners don’t pay attention to their roof until there are visible signs like water spots, peeling paint or disintegrating wallpaper.

Once these signs present themselves, however, there is usually significant damage that has already taken place. Mold, dry rot, damage to insulation, buckling walls, etc. are all common damage caused by slow roof leaks that go undetected.

Roof Blisters: Blisters are raised portions of a roof. They are usually long and thin and are caused by a gas trapped in the roofing system. The warmth of the sun causes the gas to expand and create a bubble, pushing the plies apart. This bubble is the blister. Moisture can creep into these blisters, causing the damage outlined above in the roof leaks/moisture section.

Poor Installation: Poor installation is one of the most common causes of roof damage. Depending on which source you read, a roof should last anywhere from 15 to 30 years. Poorly installed roofs may last significantly fewer years before they start to present problems to homeowners.

Wrinkling, buckling, contraction of sheets, water damage and more can all be attributed to poor roof installation.

These are just a few of the common roof problems that should be caught early to prevent costly roof repairs. A roof inspection by a qualified professional such as the inspectors at ADVANTAGE Roofing INC. can spot problems before they become too expensive. give us a call or email for a no-hassle roof inspection.


Many roofers advise that homeowners have two roof inspections done each year; one in the fall and one in the spring. These times are recommended because they fall on either side of winter, when roofs need to be evaluated for moisture damage that could have been caused by snow, ice and/or rain.

An inspection in the fall helps ensure that minor problems don't become major problems, while a spring inspection helps evaluate any damage done during the winter that may prove costly with the heavy rains of the spring that are so common.


A reputable roof inspector will provide a detailed report of the problems found so you will know exactly what’s wrong with it and how much it will cost to fix it. At ADVANTAGE Roofing INC., we take pride in our 23-point inspection process which ensures your roof gets a thorough examination.
