Panama City Roofing: Article About The Importance Of Flashing
As related to construction, flashing is what seals joints in a building, keeping water from getting to the interior. The roofing system in particular has multiple joints that are susceptible to letting water in if not properly sealed. These areas can include the chimney, hatches, skylights, towers, parapets and more. Outside conditions such as temperature and humidity play a large role in the openness of the joint itself. Flashing creates a watertight seal at these locations to provide sufficient protection against weather.
All parts of the exterior of a building come together to create an interior that is completely protected against the elements. The roof, windows, walls and other parts of a structure coordinate to create this protection. Water is the most threatening element to the interior of a building and must be kept away from joints, where penetration is most possible. In addition to properly installed roofing materials to promote proper drainage, flashing is also very important to defend against water penetration. Speaking with a Panama City roofing professional about their use of flashing is absolutely necessary.
Flashing is generally a simple process. It is installed where roofs intersect as well as intersections with walls and parapets. It is usually made of strips of metal that are non-corrosive. They are made of a base and cap that is often called counter flashing.

The base flashing is actually connected to the roof. The cap flashing is attached to the base flashing's extended portion or the wall itself. It protects the joint where the wall and roof intersect.
The flashing can be different depending upon the type of roof used. With a tile or asphalt roof, base flashing will often be intertwined into the roof sheathing to provide even more tightness of the joint against water penetration. Cap flashing will always be in steps following the slope of the roof. The installation of each of these must be done properly to avoid binding, or the joints will not function as necessary.
Occasionally, repairs will be required for the flashing to avoid leaking. If the flashings are not working properly, this could be a sign that a new roof is needed. Depending upon the extent of the problem, repair of the flashings could require replacement of large sections of the roof itself. This is why quality installation by a professional from the beginning is very important. As a result, utilizing quality flashings to protect the roof and the building as a whole from water and ice is a solid plan.
