Observation Report Gage Q 460 Tonkawa Road <br /> 4. The roof above the wood deck boards consists of wood shingles and <br /> is assumed to be insulated with additional 2x members. <br /> 5. The north window wall at the living/sitting room consists of full- <br /> height laminated veneer lumber (LVL) structural mullions. The <br /> LVL beams frame into the LVL mullions and are connected with <br /> metal-plate fasteners/hangers. <br /> 2. Damaged wood shingles and wood soffit were observed near the lightning strike <br /> location at the roof ridge at the north end of the house. <br /> 3. A large window at the north window wall was shattered by the lightning strike. <br /> 4. The northernmost timber roof rafter at the west slope of the north room was <br /> pushed inward approximately 2-inches at the top of the member. This was most <br /> likely due to the energy impact of the lightning and/or the explosion of the smoke <br /> detector. <br /> 5. The vertical structural window mullions and horizontal members at the north <br /> window wall consist of LVL members. The smoke detector was mounted to the <br /> eastern vertical LVL mullion. <br /> a. Blackened and splintered wood in the eastern vertical LVL mullion was <br /> observed near the explosion location. <br /> b. Melted and broken electrical wires were observed near the explosion <br /> location. <br /> 6. Scuffs were observed in the wood ceiling/deck boards,timber rafters,and wood <br /> trim. These scuffs were presumably caused by flying debris after the smoke <br /> detector exploded. <br /> 7. No other structural damage or distress was observed. <br /> Pie Consulting&Engineering Page 3 of 5 MN716226.00(000) <br />
