Low Maintenance: Routine inspections and minor repairs ensure longevity without extensive upkeep.
Weather Resistance: This roofing type provides strong resistance against wind, hail, and heavy snow, making it suitable for Canadian climates.

Professional roofers typically install modified bitumen roofing using these steps:

Surface Preparation: The roof is cleaned and inspected for damage.
Primer Application: A primer enhances adhesion between the membrane and roof deck.
Membrane Installation: The modified asphalt membrane is applied using torch-down or cold adhesive methods.
Sealing and Flashing: Flashing is installed at critical areas such as vents and chimneys.
