The Great Canadian Roof Doctor supplies and installs fibreglass Shingle Roofs.  
Fibreglass shingle roofs need to be maintained. 

This includes being kept free from debris, in order to live out an expected 15 to 20 years. 

Asphalt fibreglass shingle roofs deteriorate from the colored granules dislodging and falling into the gutter and from the asphalt drying out. 

This aging process can be stopped by keeping the granules bonded on the shingle and coating the asphalt with Dr. Shields Canadian Roof Armor. A sealed roof will live twice as long than a non-sealed roof. 

When you are considering a new fibreglass shingle roof, don't just re-roof & settle for another 15 to 20 years of shingle life. Take advantage of a new sealed roof to avoid re-roofing ever again.
