Though Denver roofing may appear to be simple in construction, roofing is actually made up of many complex parts that are responsible for shielding a home from all types of weather. From the trusses to the shingles, the roof is a structure consisting of many parts and layers.

The trusses are the framework of the roof. Consisting of smaller parts including rafters, posts and struts, they give the roof its shape and provide both strength and structure. Trusses are typically built of 2x4s or larger dimensional lumber depending on the size and structural requirements of the roof. Sheathing, also called decking, is the next layer of the roof. Sheathing is typically made of sheets of plywood that cover the truss framework and provide a flat, smooth area to attach additional layers of roofing. The sheathing also adds strength and stability to the roof. As the substrate for the weatherproof layers of roofing, it is important that fasteners be appropriate in strength and size and be spaced property.

Insulation is a layer that is installed underneath the sheathing inside the attic space. Both the floor and the ceiling of the attic should be well insulated as required by local building codes. Ventilation will also be added at this point, with holes cut in the sheathing to accommodate small vents that help move warm air and moisture through the attic.

A roofing contractor from All Around roofing of Denver CO can answer any questions you have about metal roofing or siding.

The next layers of roofing form the weatherproof portion of the roof. The underlayment is moisture proof roof felt or tar paper that is attached directly to the sheathing. Should any of the roof shingles fail, the underlayment will prevent water from soaking into the wooden portions of the roof structure. The top layer is the shingles, which is the final layer of weatherproof material. They are designed to provide long term protection from wind, rain, snow and ice. Flashing is then installed around any joints in the roof to prevent moisture from seeping in through the cracks. This can include edges, corners, chimneys, skylights, vents or other joints that have been created by the shingles.

Gutters complete the roof with their channels to guide rainwater away from the home. Gutters are attached to the wooden ends of the eaves of the roof which are called the fascia. Soffits are the wooden finish work that connect the fascia to the siding of the house. The roof is now complete and is weatherproof, strong and ready to protect the occupants of the home.
