Most Common Roofing Problems Found During Roof Inspections in the GTA
Missing Shingles/Exposed Plywood
One of the most popular and common damages found during a roof inspection is missing shingles and/or finding exposed plywood, likely caused by heavy wind storms, animals or deteriorating due to age.
Many outdated roofs will not have an underlayment under the shingles, which increases the risk of damages, when shingles are blown off or plywood is exposed. It is most common for outdated 3-tab shingles to blow off, and to find small rectangular shingle tabs around the property. It is important to cover any exposed areas immediately to avoid further damage inside the attic and/or home. If you find yourself finding new tabs every season, it is important to consider a roof replacement and upgrade to architectural shingles with higher winder resistance.

Poor Ventilation

Lack of Insulation
During the winter season, have you ever noticed that some homes will have more snow on their roofs, compared to others? You may think that having less snow on your roof is a good sign, however it is not. If the snow on your roof is melting faster than surrounding homes, it is most likely a sign of insufficient attic insulation.
Attic insulation acts like a blanket, keeping all of the air in your home rising, more contained. If you are lacking insulation, that warm air during the winter season will rise into the attic, causing the snow to melt at a quicker rate. The current standard for attic insulation grading in Ontario is R-60, meaning you need a specific amount of insulation in the attic in order to meet the requirement. On average, typically 25% of every homes heat escapes through the attic. Ensure your attic insulation levels meet the requirements to improve energy efficiency and increase savings.

Animal Damage
Animals may also cause damage to areas of the roof where they believe there is an access point for them to nest. If the access point is blocked off, the animals will typically find another home or area.
Another very common issue found amongst roof inspections are chewed up vents, which allow animals to enter the attic for habitation and nesting. If a roof has plastic or aluminum vents installed, it is susceptible to animal damage. A simple change from plastic/ aluminum vents to animal proof galvanized steel vents, will immediately deter any animals trying to access the attic from the vents
