The owner wants to remove the exisiing roof and replace it with a new tile and retained me to evaluate the existing framing so as to ascertain by professional judgment the maximum allowance for new roofing materials. The following report explains my findings. History The home was constructed approximately 20 years ago. The roof is constructedwith manufactured plated roof trusses set at 24 -inches on center. The slope of the roof appears to be approximately 4 -inches of rise to each 12 -inches of run. The Kitchen area represents the most critical portion of the residence due to 6e clear span ofthe truss without any support from interior partitions. The home appears to be consistent with the quality of home typically associated with Conventional Construction or Prescriptive methods. Therefore, it is a safe assumption that the interior walls were not intended to support the trusses and that each truss was designed to span the exterior bearing walls - approximately 28 -feet. The trusses are constructed from 2x4 lumber and the connections (joints) are achieved with light gauge steel "pressed" plates rather than nailed connectors. The manufacturer of the trusses or the plates has not been identified. Trusses of this kind are generally designed for the type of roof that was originally applied. In most cases the truss manufacturer uses a dead load (permanently applied materials) one the upper chords equivalent to a minimum of 10-psf. The same is applied to the horizontal bottom chord for insulation, ceilings and miscellaneous loads. However, caution should be taken inasmuch as trusses have been designed for less capacity (closer to actual weights applied) based on the demands of the developer. The current roof materials consist of composition asphalt materials and small stones. This is applied over builders paper and '/2" plywood sheathing. The cumulative weight of this materials (assuming the application of two layers of roofing) is approximately 5 to 6 pounds per square foot — the same as a lightweight tile. The quality of lumber appears to be a number two grade Douglas Fir although I could not locate the grade stamps. The plates were in generally good condition except for one or two trusses east of the attic access panel. The plates at the peak of the truss were split and the top chords appeared to be separating. I suspect that this was not a recent development and that the condition of the trusses have reached a level of equilibrium. However, the owner was alerted to this problem and the possibility of damage from water leaks. It is highly recommended that the trusses be repaired where this condition occurs. I believe that the capacity of the roof should be limited not to exceed an approximately tile weight of 5 to 6 pounds per square foot. The weak link in the system appears to be the press -plates. The contractor supplying the materials must be made aware of the weakness of these plates and inspect carefully when loading the roof. It is, therefore, my professional opinion that the owner restrict the choice of materials to a light -weight composite tile that will no exceed five to six pounds per square foot above the weight of the existing sheathing and building paper. Furthermore, the contractor should stop the new the at the existing room eave. The existing patio cover should not be included in this report as it is not': laterally supported at the North side.

WISH P.E. HAS BEEN A MEHBEROF,THE STRUCTURAL ENGINEERS ASSOCIATION OF SOUTHERN CAUFORN A SINCE 19,83. Page 2 I inspected the ceiling within the house and found it to be in good condition. There was no indication of excessive deflection which might have caused cracking ofthe existing gypsum board at the paper taped seams. There was one crack in the ceiling between the foyer and the dining room. This appears to be a non-structural crack caused by the deflection of the trusses at the clear span. Although the bottom chord of the truss is generally designed not to bear on interior walls, over time creep sets into the materials which causes the lower chord of the truss to come to bear on the top of non-bearing partitions. The area adjacent between foyer and dining room are a clear span which will deflect in time differentially and this,is the most likely place for a crack of this type to occur. The crack IS NOT representative of a structural failure and can be repaired by the use of a fabric tape. Construction Limitations: 1. The contractor shall not load or stack roof tiles adjacent to or above any long span headers or beams. This includes but is not limited to garage header, beams above sliding glass patio doors, intermediate beams such as those in the living -room, or any opening exceeding 4'-0" in width. All materials should be located above solid bearing walls that can transfer the temporary weight to a known foundation. . 2. The contractor shall not place loads or stack materials on cantilevered roof projections. 3. The contractor shall be aware of all changes to structural members including beams and joists. Changes such as difficulty closing doors and windows shall be reported to the engineer of record for possible remedial work. 4. The contractor shall look for damaged trusses and truss plates prior to loading the roof. Cracked or split truss chords shall be reported to the engineer of record who will determine the appropriate repair. In cases of manufactured plated trusses, damage may require special corrective repairs which is only possible by analyzing the capacity of the truss. This is specialized work and recommendations to specialists in this field can be recommended. This report can not guarantee the uniform quality or the maximum load capacity of -the existing materials and special caution should be exercised to prevent possible damage. ' 5. The increased weight of tile applied to the roof may have an effect upon the deflection of the roof eave. Where excessive or noticeable deflections occur at extended eave, the engineer shall be notified to determine the cause and to provide remedial measures. I ` 6. The .roofer shall provide all ICBO reports .required by the building official prior to obtaining permits and commencing work. Conclusions: The owner has been made aware that changes in the lateral load resisting system may occur due the additional weight of the tiles. The design of buildings such as this are typically designed to the worst conditions caused by either wind gusts or seismic forces. In most cases, wind governs. I do not believe that the additional weight of the lightweight tile materials will add. sufficiently to shift the balance from wind to seismic compliance. The owner has chosen to add the new tiles and not upgrade the lateral system of the structure (generally not recommended or considered economical). The structure is expected to perform the same as it had with the composition and stone roof. Additional movement may occur due to the increased weights' and this may result in increased cracking of stucco and gypsum during a seismic event. Size and depth of existing headers has been assumed and can not be field verified without removal of exterior lath and stucco and interior gypsum board. Therefore, the contractor will notify the engineer of any conditions causing excessive deflection (bending) should occur.
