Alamo Heights Roofing: Article About Preventing Water Damage
Even in dry climates, moisture can penetrate roofs that are old or deteriorated. An improperly installed roof can also let destructive moisture in. Often people don't know there's a problem until their ceilings become stained or, in the worst cases, start dripping water. Whether inspecting and making necessary repairs to an old roof or building a new roof, the professionals at Alamo Heights Roofing know how to prevent water damage.
Roofs that are angled rather than flat will have valleys where water can collect and potentially seep beneath the surface. There may also be vent pipes or chimneys protruding through the roof. Moisture can penetrate the interior if these openings aren't properly sealed. Metal flashing is usually installed to seal these areas.
Roofs end at the walls of a building. Anything on the roof could potentially drain into the walls unless it over hangs the edge of the walls. The part of the roof that extends beyond a wall is called an eave. The purpose of an eave is to carry water beyond the structure. It cannot stick out over the property line and create a drip line on a neighbor's property. Although utilitarian in nature, eaves may be decorated in a variety of ways.
There is usually an open space beneath the eave. Although moisture normally wouldn't get in that area, wind can blow debris there.

Birds, squirrels or mice might think it's a good place to build a nest, hide food or even gain access to the interior. The exposed underside of eaves is therefore usually enclosed by means of a soffit. Soffits may or may not include vents, depending on the climate and local building codes. A soffit is a simple flat surface that starts at the edge of the eave and ends at the structure's wall. Soffits were traditionally made of wood. Metal came into use later. Contemporary soffits are often vinyl.
The outer edge of the eave and soffit is usually covered by fascia. Fascia is a strip or band of material that finishes the appearance of roof components. It's often made of wood but may be constructed from other materials. Although it also helps prevent water, dirt and pests from damaging the building, people generally regard fascia as decorative trim.
Rain gutters are often installed on the fascia in many regions of the country. Gutters attached to the edges of eaves are called eave troughs. All the gutters collect the water runoff and channel it to downspouts to soak harmlessly into the ground. Newer gutters and downspouts are nearly always made of aluminum rather than wood.
