Independence Roofing: Article About Major Roof Components
A new building is ready for the first roof components after the truss has been properly installed. Although the framework provides the structure with strong support, the actual roof covering protects the interior from rain, snow, wind and UV rays. A roof can have various design elements such as ridges, valleys and eaves, but its most important components are the underlayment, flashing and shingles. The appropriate roof type depends on the location of the structure and the area's most common weather conditions. Regardless of the specific needs, however, each roof must have the basic components in some form. For more details, contact an Independence Roofing professional.
Underlayment goes directly onto the roof's decking and serves as a layer of protection against moisture. It is often a thick, black felt paper that seals off the sheathing. Some underlayment, however, is constructed of synthetic materials. With the added safeguard, sheathing and rafters are kept dry and well-maintained. The flashing and major roofing materials are then added and secured to the decking below.
At intersections such as hips or valleys, rain and melting snow can easily seep through the cracks and damage the framework underneath. Sections of metal are placed along these areas to prevent water from entering the lower levels.

Flashing is also necessary around penetrations such as chimneys and vent pipes. When the roof meets a vertical wall, the joints can be vulnerable to water leakage, and these require flashing as well. The metal can be made from a variety of materials including untreated copper, lead-coated copper, stainless steel and a galvanized alloy.
Whether the roof is built with shingles, tile, metal panels, wood, or other materials, the covering is the most important component for shielding against wind, precipitation and harmful UV rays. Some of these materials have been used in roofing for hundreds, even thousands, of years. The lifespan of all materials can vary depending on the roof type.
Because roof edging and trim both block water infiltration, they are also among the most important components of any roofing system. A drip edge, for instance, directs runoff into the gutters so that it won't drip behind them and rot the decking or fascia. Occasionally drip caps are installed above doors and windows so that rainwater will drain away from the structure's framing.
If a roofing system has solid sheathing, adequate underlayment, flashing and a strong roof covering with trim for sufficient drainage, it will serve for a number of years as the building's safeguard against damage. These components are essential for every rooftop because they keep the attic and other interior spaces clean and dry.
