First Street, Suite 260 San Jose, CA 95112 0 Attn: Jack Hnilo Re: Examination of Existing Building Roofs at Cupertino Loc-N-Stor, 10655 Mary Ave., Cupertino, California Mr. Hnilo, Dennis B. Ahearn, S.E. William S. Knox, S.E. Tim D. Hyde, S.E. AKH Job No. M03-041 As you requested, I visited the subject building yesterday with MOCEier(hi's I S&r of Central Coating and examined the roof and surrounding conditions. I understand that Central Coating is scheduled to install new foam roofing over the existing roofing on the ten buildings at the site, and that the Building Inspectors from the City of Cupertino requested an examination of the conditions by a Structural Engineer and a statement indicating compliance with CBC Sections 1515 and 1516 in Appendix Chapter 15. The buildings vary in size from approximately 450 sq. ft and 625 sq. ft. for the modular buildings, up to 14,000 sq. ft. for the largest storage building. For all but the small modular he roof is typically supported by ''/z" plywood on 2x6 No. 2 joists @ 24" f mi b ring walls and beams at 10 feet on center. Some of the buildings havil a el three feet high on some sides. I understand that the new foam will ext t t of t e parapets and be sealed at the parapet cap flashing. The existing roofing is reportedly less than seven years old, but is experiencing leaking and localized ponding in a few locations. As you indicated, the City is requiring demonstration of compliance with Sections 1515.1.1 through 1515.1.6. My observations reaardina each of these cpctinna are listpri hpinw- 1515.1.1: Roof structure sufficient to sustain weight of added roofing I observed the roofs of all buildings from above the buildings and from below in several areas, from inside the storage rooms. There is no roof insulation and the framing is exposed in the storage rooms. There are no signs of excessive deflection, overstress or other distress, and the roof structure seemed to be quite firm. As you indicated, only one layer of roofing (built-up roof with cap sheet — no gravel) exists throughout. Analysis of the joists shows that they are more than sufficient to support the existing roofing plus the proposed foam roof, with the required live load of 20 psf. Based on the framing's capacity, its apparent good condition, and the fact that the installed weight of the foam roofing is less than one pound per square foot, (1.0 psf), the existing framing could readily sustain the added weight imposed by a new foam roof. 1515.1.2: Roof deck structurally sound During my examination I walked over the entire roof area, including those near the roof drains and overflows. No "soft" areas were observed. Based on the framing as specified in the item above, and the apparent firmness of the roof in general, the deck appears to be quite sound. File: P:1Central Coatg\M03-04111003-041 Roof Exam Report.doc Page 1 of 2 1505 Meridian Ave., Suite B, San Jose, CA 95125 • Phone (408) 978-1970 • Fax (408) 267-7919 1515.1.3: Roof drains and drainage sufficient The roof slope appears to be sufficient in all but a few localized areas. I understand that the new • foam roofing will be sloped to eliminate these low spots. The size of the roof drains and overflow appear to be consistent with Code requirements based on the respective areas served, although calculations for this were not performed. I understand that the gutters and downspouts will be reworked as part of the re -roofing, including examination for possible decay in the surrounding framing. n LJ is 1515.1.4: Existing roof secured to deck The existing roof appears to be sufficiently adhered to the deck._; Noaareas,of) blistering were apparent. I OCT 0 3 2003 1515.1.5: Existing insulation is not water soaked There is no insulation in any of the storage buildings, and the insulation in the apartment and office portions of Building F is not soaked or moist. 1515.1.6: Fire -retardant requirements maintained The installation of the foam roofing will not affect any of the building's fire -retardant properties. Also, Section 1516.2.2 allows the installation of one roofing overlay over a cap -sheet surface, which is what currently exists on these buildings. The weight of another built-up roof would be at least three times that of the proposed foam roof. Fa �In addition to the conditions noted above with regard to the s cti a e other observations. These are as follows: 1. There appears to be no rooftop HVAC equipment on any of the buildings, so no flashing around sleepers and duct penetrations will be required. 2. There is at least one area where the metal cap flashing atop the parapet wall is missing. I understand that the cap flashing will be replaced and/or repaired as necessary throughout. In general, I observed no conditions that would preclude or should prevent the application of a new foam roof on these buildings. Please feel free to forward this document to the appropriate Building Department personnel for their review, and contact us if you have any questions. Sincerely, G4 q) 7; Tim D. Hyde, S.E.
