DAJDESIGN ARCHITECTURE, INTERIORS ROOF FRAMING SYSTEMS Description: Access to view the roof framing is through an exterior attic hatch in the south wall of the south facing gable. However, not all areas of the roof framing were visible from this location. The northwest portions of the house roof were not visible nor was the roof framing over the covered front patio. Also, the upper portions of the roof appear to have been over -framed on top of the south facing gable without access to this space. The below analysis is for the visible portions of the roof only. However, it is likely that the non -visible portions of the roof are constructed in a similar manner to those that are visible, as common materials and techniques are found on many houses built around the same time in the Louisville area. vAThe roof framing over the west side of the house was likely an original north -south gable that was later ` connected to an east facing gable in the northeast part of the house. The east facing gable is still visible though partially covered on the south side. Where these two roofs meet, the roof forms a hip at the northwest corner. The south part of the house forms a south facing gable roof at a steeper pitch than the previously described roof elements. This roof is connected to the lower roofs with a taller north -south gable with a steeper pitch on the east side than on the west side, where it connects to the original gable ridge. The covered patio roof is a shed roof sloping north that is partially framed on top of the east -west running gable. The bay window roof sits lower than the other roof elements and is a hipped roof. There is a small portion of low-pitched roof south of the bay window that partially covers the east side entrance room. Where observed, the roof rafters are 2x4 at 24 inches on -center and the ceiling joists are 2x4 at 24 inches on - center. The roof sheathing is an original layer of 1x skip sheathing with a second layer of OSB sheathing on top. There is no ridge beam or collar ties. There are several 1x vertical and diagonal braces supporting the rafters, but these only occur in a few places and do not appear to bear on walls below. Part of the original south aspect of the east facing gable is visible in the attic space. The roof framing over the east entrance room is partially visible and is 2x4 construction, but it is unclear how this roof is supported. The north portions of the house, including the bay window and front patio roofs were not accessible for analysis. Where observed, the insulation in the attic is a combination of blown -in cellulose and fiberglass batt insulation with a depth of approximately one foot, maybe more in some areas. This insulation appears to cover the entire house roof above conditioned space. It is unclear when the roof insulation was added, though it is not original. Original roof rafters and sheathing with new sheathing on top. Vertical Ix supports do not bear below. 700 PINE PAGE - 18
