While at night, when the temperature drops the materials tend to contract. Portland’s quick changing weather can cause a roof’s framing lumber to reduce in size and swell depending upon moisture of its surface. Decreasing and enlargement causes the roof sheathing as well as rafters to move. That is why, the flashing materials are supposed to be able to endure this movement and carry on to be leak-proof for your Portland roof. A well-engineered, as well as installed metal flashing system can hold this movement without any problems.
