Dallas Roofing: Article About Roofing Styles
The overhang of a roof is an important but often forgotten aspect of the home's roofing system. In addition to being an excellent place for anchoring the rain gutters, the overhang is also where soffit vents and continuous vents are built into the attic for the purpose of ventilating the structure. An overhang of greater than 12 inches also helps to shade the home's windows and exterior walls, making the house more energy efficient. When a home's overhang is insufficient or non-existent, homeowners can have experienced Dallas roofing contractors add one onto the home by way of its rafter tails.
The easiest style of overhang to add is called a simple eave. These are nailed onto the ends of the rafters and must measure less than 2 feet in width. The boards will run the length of the entire exterior wall. The roofers begin by removing the fascia and soffit boards to expose the rafters. They then measure the space between the rafters and use stock sizes of lumber to slide between them. The wooden extensions are attached to the rafters with long spikes, which resemble traditional roofing nails. Spikes are placed every 6 inches along the extension boards and are nailed into position with a framing nailer.
If the home's attic has been filled with loose fill insulation, working from the attic's interior could be difficult for the professional roofers.

The extensions can be attached from the exterior side of the house, but this process necessitates the removal of some of the roof's sheathing.
Once the rafter extensions are in place, then they will need to be connected to the roof's decking to make the structure complete. This can be done with additional sheathing boards or with the same lumber that was used for the extensions if it is close in thickness to the sheathing materials. If the home's existing roof already has a radiant barrier in place, the new portions of roofing can have pieces of the reflective foil installed onto them before they are nailed into place.
Once the framing of the newly extended eaves is complete, then the roofers will cover the extension area with a vapor diffusion retarder, roofing felt, and then the desired shingles or tiles. If the roof's existing shingles are near the end of their lifespan, this is a good time to have the home re-roofed. Doing this will ensure that the shingles on the new section of roof match the rest of the rooftop.
