Roof damage depends on the kind of roof and how the materials hold up under adverse weather conditions. Surprisingly, the leading reason roof damage occurs results from a lack of regular maintenance.

In addition, improper installation and using incorrect roofing materials produces unwanted results. Preventing roof failure with regular inspections and the ability to identify numerous types of roof damage can save the homeowner thousands of dollars in roof replacement costs.  Here are a few ways to identify roof damage.


Cracks

Cracking occurs with tiling, wood or asphalt shingles for different reasons. Wood shingles naturally crack with age. Cracks allows prolonged exposure to the protective underlying layer of felt material which causes it to dry and crack, creating a potential leak in the attic or crawl space.

Hail Damage

Most roofing hail damage results in cosmetic injuries with no compromise of the structural integrity of shingles. Severe wood shingle splitting, severe granule loss on asphalt shingles and fractures on tiling from hail require shingle replacement.

Wind Damage

Wind gusts reaching 50 to 75 miles per hour over the edge of the roof can create a vacuum and may damage roofing. Without secured roof decking–the flat wood nailed over the skeletal rafters–the air pushes up the underside of the roof assembly, further loosening fasteners and breaking the adhesion causing possible roofing damage with every moderate or strong wind.

Heat Damage

Aging and prolonged heat exposure causes shingle cracking. These two factors also create a breakdown of the protective roofing water sealant. Severe shingle cracking indicates the end of the shingle’s usefulness and requires replacement. Routinely replacing your roof’s water sealant keeps the roof watertight.

Gross Granule Loss

Granules add weight and fire resistance, protect the felt matting and add color to asphalt shingles. With time, gradual granule loss occurs but excessive loss of granules exposes the felt matting to the elements, shortening the life of the shingle.

Drainage Systems

Quick removal of surface water from every type of roofing requires a drainage system including gutters, downspouts, drain openings and deck slope. All parts of a roof’s drainage system need to be cleared of debris that might interfere with the proper flow of surface water at chimneys, skylights or where the roof meets the wall.

Blistering

Blistering on asphalt shingles occurs with either open or closed bubbling as the roofing ages. Open blisters expose the mat or felt lining of the shingles, allowing moisture build-up and shortening the the life of the shingles.
