Expert Diamond Certified Reroofing Video Featuring Wedge Roofing CEO Gary Harvey
When developing an expert video on when reroofing becomes necessary, Diamond Certified® sought insight from Gary Harvey, President and CEO of Wedge Roofing—a firm founded in 1976 with a long-established reputation for award-winning roofing expertise and ethical business practices.
Why Roof Age Matters More Than Most Indicators
One of the most important factors in evaluating whether it is time for reroofing is the age of the roof. According to Gary Harvey, a typical residential roofing system has an 18- to 20-year life expectancy, depending on the materials used, installation quality, and environmental exposure. In many cases, the calendar alone provides the clearest signal that replacement should be considered. As roofing materials age, their ability to perform as designed diminishes—even if leaks or visible damage have not yet appeared.
Visible Warning Signs on Shingle Roofs That Should Not Be Ignored
In addition to roof age, there are several physical warning signs that often indicate a shingle roofing system is nearing failure, and it is time for reroofing.
Roofing Materials on the Ground
Finding pieces of roofing materials, such as shingle fragments, in your yard or gutters is a strong indicator that the roof is deteriorating and shedding critical components.
Shingle Granule Loss
Granules protect shingles from ultraviolet exposure and weathering. Excessive granule loss accelerates aging and leaves the roof vulnerable to further damage.
Uneven or Distorted Roofing Materials
Uneven characteristics on the roof surface can signal structural or material failure, including:
- Lifted shingles on asphalt shingle roofs
- Missing or curled shingles on wood shingle roofs
These conditions can compromise water shedding and increase the risk of leaks.
Evaluating Low-Slope and Flat Roofing Systems
Low-slope and flat roofs present unique challenges because they are often not easily visible from the ground. As Gary Harvey explains in the Expert Resource Report, these systems should be evaluated by a licensed roofing contractor with experience in low-slope roofing assemblies.
Because problems such as membrane deterioration, ponding water, or seam separation may not be apparent without a professional inspection, periodic evaluations are especially important for these roof types.
When Professional Assessment Is Essential
While some warning signs are visible to building owners, many roofing issues develop below the surface. A professional assessment allows trained experts to evaluate:
- Overall roof condition
- Remaining service life
- Hidden vulnerabilities
- Whether repair or full replacement is the most prudent course of action
Early evaluation often prevents more extensive damage and costly interior repairs.
