Roof flashing is an important factor that most amateur roofing contractors miss out on when repairing the roof This is why it is always recommended to work with an experienced and reputable roofing contractor in Sunnyvale.
In particular, flashing refers to the process of extra protection on areas that are prone to leakages. Flashing directs the flow of water around the multiple openings. Note that without flashing, water can seep into the walls and cause them to become weaker. Most of the time, seeping goes unnoticed, which can cause long-term structural problems.
