Yes they do. The roof system of your building expands and contracts each day due to the temperature changes. As the temperature heats up for the day, the roof system will expand, while the cooler night temperatures will lead to roofing materials contracting.
There is seismic activity daily in Southern California that creates building movement, even if you cannot feel the movements yourself. Additionally, buildings periodically settle, which leads to movement.
So how does this information impact you the Customer? Roofing materials have improved since the days of hot-tar kettles. Membrane systems have better expansion/contraction capabilities that increase the Service Life of a roof system. A roof system that can flex without weakening the membrane decreases premature roof failure and lengthens the Service Life of your roof.
Increased Service Life lowers the Life Cycle Costs for owning a building. Again, finding the right Roofing Contractor that has experience inspecting a building’s roof system, and knowing the signs of what is actually happening to the roof is critical. Roof movement is only one of several key indicators when assessing a roof properly. SBR’s roofing consultants help educate the customer in understanding their assessment findings, and provide the customer with practical options and budgets.
