The existing diagonals are shown in the photos below. I wrote a description on how to add diagonals and what I saw is shown on the next page. 7901 S ADAMS WAY CENTENNIAL, CO 80122 303-221-1559 CONSUPSEROMAC.COM 4310 Dover St Page 3of3 For places where there is no wall below the horizontal beam can be sistered to the existing beam to provide additional stiffness. As I stated in the original report if the gap is 72" a minimum of a 2x6 is required. After my visit to check the repair, there is a section at one end of the house that is 10 -ft. This section can be done using a 2x8 sistered to the existing 2x4, with no diagonals down to the ceiling. In the photo below, the first diagonal on the left is an original. The next one is new. Notice the large gap at the bottom of the notch and the fact that it is on the wrong side of the horizontal. If these are installed the way that I describe, the pressure from the roof helps to hold them in place so they are not so dependent on the fastening system. If you havyl�ny questions call me before beginning. 7901 S ADAMS WAY CENTENNIAL, CO 80122 303-221-1559 CONSUPSER@MAC.COM q 3(D bow o? iOERVICES, t6 NSTRUCTION UPPORT INC.

For velocities in excess of 100 mph(ASD) attachment shall follow manufacturer's Evaluation Report Note: Table has minimum requirement. This is an ultimate wind velocity of 130 mph This house was examined with the intention to install a new concrete roofing tile system on the house. We examined the attic to see the roof supports, the house for existing drywall cracks or other evidence of movement. There are always areas that are not observable and we attempted to determine the framing method in those locations. f j - -�- Li i Project: 4310 Dover St Page 2 of 6 Using the information we collected we were able to model the support system in this house. That model for the frame is the first section, looks like this: 9000 The framing is acceptable as long as the internal supports are performing properly. The close up photos show that the supports are not properly supported. The model predicts that under a full load there is almost 900 pounds of load on each of these connections at each rafter. The spacing of the diagonals means there are several rafters for each diagonal. This is not acceptable. A series of new diagonals needs to be run that have proper notches to support the loads. The new diagonals need to be spaced properly and they need to be secured properly to reduce the potential for slippage. 7901 S ADAMS WAY CENTENNIAL, CO 80122 303-221-1559 CONSUPSER@MAC.COM Project: 4310 Dover St Page 3of6 The diagram below shows how properly notched diagonal supports should look. When the roof loaded the weight tightens the connections rather than allowing the rafter to slide past the support. The diagonals need to be spaced a maximum of 48" on -center when a 2x4 is used as the horizontal member and 72" if a 2x6 is used. Since there are sections where new diagonals are needed I recommend that new horizontals be installed. The horizontal beams can be added so the support is provided above the existing. Position the new horizontal beam between the midpoint of the rafter and a point 1/3 of the span down from the ridge. Space the diagonals 72" on -center and use a 2x for the horizontal beam. The existing horizontal beam can be left in place. Secure the bases of the old and the new diagonals using L30 brackets from Simpson and secure the old horizontal beam to the rafters using Simpson H -clips. Also block the bottom of the old beam using 2 -ft long sections of 2x4s installed perpendicular to the existing diagonals so the bottom of the horizontal beam is supported. There are 20 sets of rafters down the back -bone of the house that need the added support. On the North end of the house the rafters are single span with no intermediate supports. The location of these rafters is indicated in the photo on the next page. 7901 S ADAMS WAY CENTENNIAL, CO 80122 303-221-1559 CONSUPSER@MAC.COM Project: 4310 Dover St The model for these long single span rafters looks like this. r.n1 f X1(14111111. Page 4 of 6 The top portion is the deflection, the bottom portion is the bending moment normalized. This means any value for the bending moment over 100% is not acceptable. There are 6 sets of these rafters. These rafters can be stiffened by sistering them. The sistered rafters are modeled as shown below. 7901 S ADAMS WAY CENTENNIAL, CO 80122 303-221-1559 CONSUPSER@MAC.COM Project: 4310 Dover St These rafters can be sistered as follows: 88 1675 1. Each rafter in this section is to be sistered with an 8 -foot section of 2x6. 2. The sister is to be centered on the rafter. 3.The top of the 2x6 shall be flush with the roof deck. 4. The wood is to be glued using Locktite® PL -400, PL -375, PL -Premium or OSI SF450+ applied according to the glue manufacturer's instructions. 5. The 2x6 wood is to be attached using minimum 12d nails. 6. The nails can be pneumatically driven. 7. Install nails 6" on -center into the existing rafters. The cathedral ceiling has a large number of cracks. I modeled this ceiling as 2x8s spaced 1" on -center. The rafter spacing is based on the distance between the drywall nails. That model is shown on the right. The deflection and bending moment are both acceptable.

Please note, anytime you reroof there is a rapid change of loading as the old roof is removed and the new roof installed. This change in loading, movement of materials and men, and the pounding that occurs, can cause small drywall cracks. These are not structural. If any cracking is observed, please call our office so we can make sure that there is nothing else that may have occurred. There was no significant storage in the attic space. It is assumed that no additional storage will be done in the attic. Loading the bottom chord of trusses can change their behavior. If heavy items are to be stored in the attic consult with CSS, Inc. to make sure the loading is acceptable. This opinion is based on the conditions observed. There are sometimes areas of framing that are not observable. Calculations for acceptability are based on the conditions observed using current versions of analysis software. Change of use or loading by conditions outside of those observed can change the results of the analysis. Alterations to the framing will require a new analysis. With the above stiffening completed, this house can carry an 11 psf concrete the roofing system.

Resistance to freeze/thaw is very important in weathering situations where the roofing material is expected to with- stand repetitive freezing and thawing cycles. Both Concrete and Clay Tile must have passed the require- ments of ASTM C 1492 (Concrete) ASTM C 1 167 (Clay) for freeze thaw regions. Strength — A Concrete (ASTM C 1492) or Clay tile's (ASTM C 1 167) transverse strength will meet or exceed requirements of the specified codes. Thickness — Roof tile typically ranges in thickness from 3/8" to 11/2", depending upon composition, type and style. Quantities of Tile Per Square — The size of the the and the exposure of each course of the determines the number of tile needed to cover one square (100 sq. ft.) of roof area. When the tile is installed at the manufacturer's maximum exposure, the number of tile needed to cover one square of roof area may range from 75 to over 400 pieces. Tile Weight — The size of the tile and the exposure of each course will determine the installed weight of the roof tile. In general, the amount of the to cover one square (100 sq ft.) set at the standard 3 inch head lap, will depend on the thickness, length, width, shape and aggregate materials used in the manufacturing process of the tile. Please consult with the tile manufacturer when determin- ing the weight of the specific tile that will be used. As with any roofing material the designer should always consider the weight of the underlayment, fastening system, roof accessories and special hip/ridge treatments. MATERIALS AND MANUFACTURE Concrete Tile — Cementitious materials such as portland cement, blended hydraulic cements and fly ash, sand, raw or calcined natural pozzolans and aggregates shall conform to the following applicable ASTM specifications.

Counter battens are commonly 1/4 inch lath but may be dimen- sionally increased in size to provide a greater flow of air or moisture beneath the horizontal battens. Counter battens do not need to be of moisture resistant lumber as they do not impede moisture flow. Counter battens may also be of corrosion resistant metal or other man-made materials that meet the approval of the local building official. See table 2 on page 12. Note: /f counter battens are installed under the underlay- ment, caution must be used to prevent damage to underlay- ment or reinforced underlayment shall be used. Note: Care should be taken in selecting the proper batten design. Excessive deflection of the batten may lead to tile breakage. See table 2 on page 12. Caulking and Sealant Caulking and sealants shall be suitable for exterior use and be resistant to weathering. The caulking and sealants shall be compatible with and adhere to the materials to which they are applied. Nails and Fastening Devices Corrosion resistant meeting ASTM A641 Class I or approved corrosion resistance, of No. I I gauge diameter and of suffi- cient length to properly penetrate 3/4" into or through the thickness of the deck or batten, whichever is less. The head of the nail used for the fastening shall not be less than 5/16" (.3125") and complying with ASTM F 1667 for dimensional tolerances (+0%, -10%). Nail Length — Nailing of Batten Nails for fastening battens shall have sufficient length to penetrate at least 3/4" into the roof frame or sheathing. Nailing Tile to Batten and Direct Deck Systems Nails for fastening roof tiles shall penetrate at least 3/4" into the batten or through the thickness of the deck, whichever is less. Once the batten is installed it becomes part of the deck for fastening purposes. Nailing Tile to Battens on Counter Batten or Draped Underlayment Systems Nails for fastening roof tiles shall penetrate at least 3/4" but should not penetrate the underlayment. Nailing Accessories Where nail(s) are required for fastening accessories, such nails shall have sufficient length to penetrate at least 3/4" into the supporting member. Screws — Corrosion resistant meeting code approval equal of sufficient length to properly penetrate 3/a" into or through the thickness of the deck or batten, whichever is less. Screw diameter and head size should be selected to meet good roofing practices and the screw manufactur- er's recommendations. See above section on nail length for additional requirements. Staples for Battens — No 16 gauge by 7/16 inch -crown by minimum 11/2 inch long corrosion -resistant staples. Flashing — Flashing shall be installed at wall and roof intersections, wherever there is a change in roof slope or direction and around roof openings. Where flashing is of metal, it shall be of; 0.019" Galvanized (G90) 0.019" Aluminum 16 Oz Copper 3 Ib Soft Lead. Underlayment Materials Single layer underlayments shall meet the minimum requirements of ASTM D226 Type II (No. 30 Felt) (ASTM D4869 Type IV), or approved equal. COPYRIGHT 0 2015 TILE ROOFING INSTITUTEMSRCA Uniform ES ER -2015 01/2000 Revised 7/2015 INTRODUCTION These recommendations are meant for areas that may experience occasional storms, but not regular repetitive freeze thaw cycling. In locations where the January mean temperature is 25 deg. F (-4 deg C) or less or where ice damming often occurs, the TRI /WSRCA suggests refer- ence to the Concrete and Clay Tile Roof Design Criteria Manual for Cold and Snow Regions. While generally con- sidered the minimum standard, proper adherence to these recommendations and attention to detail and work- manship provide a functional roof in most all moderate cli- mate conditions. Local building officials should be consult- ed for engineering criteria or other special requirements. The manner in which tile roofs are installed makes them a highly effective water shedding assembly that affords years of service and protection. The effectiveness of a tile roof system as a weather resistant assembly however depends on the proper installation of all the tile roof components, and installing them properly is critical to the performance of the installed system. Since tile is installed across a wide range of climatic and geographic conditions, there are a variety of details that must be considered in preparing an effective installation. The minimum recommendations shown for moderate regions are effective for a relatively wide range of condi- tions including occasional storms or snow. While it is not practical to prescribe precise solutions for all conditions, the following has been provided to offer suggestions for various treatments in a most climatic climate application. Local building officials should always be consulted to learn of special requirements that may exist. Some of the changes contained will require code approval. This manual provides the minimum design recommenda- tions with optional upgrades for the installation of under- layment, flashings, fastening and related measures to provide a weather resistant roofing assembly for concrete and clay tile. Designers should be familiar with local climatic conditions and make sure that they are reviewing the proper design manual. Please see the following list of reference publica- tions for additional information.
