Commercial Roofing Services
Sanderson Roofing has completed countless Ottawa commercial roofing projects in its many years of business. Roofing products used include:
Cold Applied Modified Bitumen
The use of cold-applied roofing has become an attractive alternative to hot asphalt or open flame roofing methods. These roofs typically have a mechanically attached base sheet, and a second ply of modified bitumen membrane installed in bituminous adhesives or in a “peel and stick” method.
Torch Applied Modified Bitumen
Torch Applied Modified Bitumen roofing is another method of application, however because of the fire potential, it should only be applied by experienced roofers and should not be applied on older wooden structures.
Signs Of Flat Roof Damage
Changing temperatures cause your roof to expand and contract which triggers movement in the roofing system. This eventually causes the membrane to age and crack, or even split.
The sun's UV rays cause roofing to dry out and crack which results in general deterioration
Over time, nails may begin to protrude through the top surface of the membrane causing leakage.
