Causes & Signs Of Aging: Deterioration Of Asphalt Shingles

Causes & Signs Of Aging: Deterioration Of Asphalt Shingles

A roof needs routine care and upkeep to operate correctly and endure as long as possible, just like everything else. However, wear and tear are unavoidable, and even the best-built roof will eventually deteriorate over time.

The frequency and extent of the shingle deterioration that certain homeowners could experience are the only notable variations. Most of the time, it all comes down to the climate and temperatures of your residential or commercial property. A homeowner who lives in a region with intense sunlight, heat, rain, or snowstorms will undoubtedly see a greater rate of roof deterioration than someone who lives in a more temperate climate.

Roof damage can be reduced by conducting routine interior and exterior inspections to find any small issues. A roof inspection in Orangeville should be performed by homeowners at least twice a year, in the spring and the fall. Checking your roof after a severe windstorm or an extremely harsh winter storm is also a smart idea.  Additionally, routine inspections could uncover weather-related damage that wasn’t initially seen because some types of storm damage won’t manifest themselves until the seasons change.

Your finances, your health, and your safety may all be at risk if leaks and roof damage go undetected. We can assist you by giving you the fundamental warning signs that your roof is degrading, which should enable you to take pre-emptive measures and avoid paying much more for repairs or replacements in the future.


The following factors are the most frequent causes of shingles deteriorating in Orangeville sooner than predicted in harsh weather:

  • Rain, Snow and Ice: Moisture is the number one opponent of roofs. It may weaken the structure, bring on mildew, destroy the deck, or even harm the insulation. While most roof leaks are caused by rain, melting snow frequently re-freezes and forms ice dams, which prevent water from properly draining into the gutter and can cause water to back up under your roofing materials. This may cause significant structural damage.
  • Sun: The most frequent adversary of roofs, the sun assaults your roof with heat and harmful rays, causing shingles to deteriorate over time. Most of the damage is caused by thermal expansion, infrared radiation, and ultraviolet light from the sun.
  • Wind: Strong winds can lift, curl, and tear the shingles off your roof, exposing the underlayment and leaving your roof susceptible to water damage and serious structural damage. High winds can cause damage to the roof’s corners, edges, and ridge line in particular, although the entire roof structure is frequently ripped and penetrated by flying debris.
  • Hail: Hail can leave dents that cause the minute protective granules that ordinarily shield your property from harmful UV rays and increase the capacity of the roof to shed water to get displaced. The asphalt coating and even the fibreglass matt may become directly exposed to the elements as a result of mineral granule loss, drastically reducing the lifespan of the roof tiles.
  • Lichen: Moss and algae can over time degrade timber and harm structures in addition to staining your roof. Lichen can be acidic and has threads that can pierce the shingles, both of which can cause serious harm. Lichen doesn’t trap as much water against the surface of the roof as moss does, though.
  • Overgrown trees: Tree limbs can seriously damage your roof by poking holes through your shingles. On your roof, accumulated leaves can block your gutters and cause them to retain moisture. Water can leak into your home due to improper drainage, the presence of water, and too much moisture can result in rotting and other damage.


Here are some of the easiest-to-see indicators that your roof is rapidly deteriorating and losing its effectiveness;

  • Curled-Up Shingles: Have you ever observed how a leaf changes as it ages? Typically, it decreases and folds upward. Shingles experience a similar phenomenon. Asphalt shingles have a propensity to curl upward over time, which produces uplift from the roof structure. The main causes of this incident are extreme dryness and thin shingles.
  • Deteriorating Shingles: Asphalt shingles are typically susceptible to degradation, unlike metal roofs and other more durable roofing materials. Deteriorating shingles are simple to spot as they will look drastically different from shingles still in good condition. It would be beneficial if you were constantly on alert for stained and worn-out areas of your roof. To avoid any potential leaks, you should always make sure to replace them as soon as you notice them.
  • Blistered Shingles: The shingles would appear to have blisters on the surface, as the name implies. It would take the form of a bubbled-up surface brought on by the heat-induced expansion of moisture beneath the tiles. Houses in warm, humid climates are more susceptible to this occurrence. Similar to other warning indicators, you should always make sure to replace the blistered shingles with more heat-resistant ones.
