Roofs are like the buildings that they cover, they come in different shapes and sizes and the life expectancy of the roof also differs with the type of materials that are used in construction of them.

Even though asphalt shingles have a typical life expectancy of 15-25 years and “BUR” – multi-ply membrane roofing, including tar and gravel roofs, have a life expectancy of about 5 years per ply.

The life expectancy of any roof significantly relies on many factors besides its composition, including the condition of the roof decking, the installation workmanship and proper roof ventilation.

Annual roof inspections are recommended to make sure all of the working components of a roof, as mentioned above, are maintained and performing properly.
