HICKMAN SYSTEMS, INC. 30700 Solon Industrial Pkwy. - Solon, OH 44139 Bus.: 440-248-7760 Fax: 440-248-6524 REPAIR AND MAINTENANCE INTRODUCTION Generally, W. P. Hickman roofing systems are warranted up to 5, 10 or 15 years. These warranties, in the event of a leak, will cover the cost of labor and material to correct problems in the roofing system that are caused by faulty workmanship or a W. P, Hickman supplied product. In many cases, the Hickman roofing system is installed and terminated at building components, such as walls, ducts, stacks, masonry, etc., which may fail and cause a leak. Such a failure is excluded from the Hickman warranties. Periodic maintenance to the roofing system will help to address those locations where moisture could infiltrate and cause damage. It is imperative that the building owner recognizes the importance of preventative maintenance in an effort to increase the life expectancy of the roofing system beyond the warranty period. PREVENTATIVE MAINTENANCE 1. General Care and Maintenance m Owner's Responsibility The following is a list of general ca re and maintenance requirements for W. P. Hickman Roofing Systems. These maintenance items will help attain maximum performance from the roofing system. Provide proper drainage. Keep the roof surface clean of leaves, twigs, paper or accumulated dirt at drain areas, to avoid clogged drains. Excessive ponding of water on the surface of the membrane will increase the probability of moisture entering the structure in the event of a puncture or cut in the membrane and will also reduce the life expectancy of the roofing system. b. Avoid degrading the roof membrane. Due to possible degradation, do not expose membrane to the following: 1. Liquids containing petroleum products 2. Solvents 3. Grease usedforlubricating rooftop units 4. Oils (neworold) used forairconditioning orcompressorunits 5. Kitchen wastes or other fats 6. Chemicals Catch pans and proper drainage of these pans or other means of protection may be used for membrane protection. Prolonged exposure to these materials will cause possible degradation of the membrane if spills are not removed. W. P. Hickman Systems may be contacted to identify certain effects of these materials on the membrane. Limit foot traffic. Unprotected areas of smooth surface roofing membranes are more susceptible to damage from reoccurring foot traffic. Care must be used to avoid damage to the membrane. CAUTION: The smooth surface roofing membrane is slippery when wet. W. P. Hickman recommends the placement of Hickman Walk Treds to and from all areas needing maintenance access. Exercise caution when not walking on walkways, particularly while walking on smooth surface membrane system, since ice and frost build up may not be as visible. Exercise care with tools and equipment to avoid puncturing the membrane, flashings and single ply systems when it is necessary for workers to be on the roof to service rooftop equipment, e.g., HVAC units, antennas,- etc. Walkways should be provided if regular traffic is required or if rooftop equi'pment has a maintenance program. When servicing units, care should be taken to avoid placing metal doors, lids, pans, or sharp objects on the roof membranes. When moving units or equipment on roofs, avoid overloading and membrane damage by placing smooth plywood over the membrane prior to moving the equipment. PAGE 1 Avoid damaging the membrane if the removal of snow is necessary. Use plastic shovels and pay particular attention when Working around curbs or other areas where flashing can be damaged. Snow blowers and shovels with sharp edges must not be used. Exercise care when painting walls (above the flashing) or other rooftop equipment. Remove all debris (such as, glass, bolts, nails, screws, metal shavings, etc.) and any other material that may promote punctures or cuts to the membrane. Metalwork- Keep roof maintenance items, such as counterflashing, caulking, pitch pockets, metal curbs and metal pipes, sealed and watertight at all times. Perform inspections at least twice a year. Caulking is a maintenance item (not warranted by W. P. Hickman Systems, Inc.) and should be addressed as needed. Roof membrane surface coatings and mineral/aggregate loss are considered maintenance items and should be replaced as needed. CAUTION: The application of surface coatings not approved by W. P. Hickman Systems may result in membrane damage, 2. Periodic Inspections A periodic inspection program should be established bythe building owner and manufacturer's representative. Roof inspections should be conducted by qualified personnel, beginning when the roof is completed and continuing at least twice a year thereafter, preferably, in the spring and the fall. A professional service plan is available through a W.P. Hickman subsidiary, A.M. Technologies. Ask your Hickman Representative for details or call A.M. Technologies at (440) 248-2258. The inspection should concentrate on "high risk" areas such as roof hatches, drains, all rooftop equipment and perimeters, as well as general inspection of the entire roofing system. Periodic inspection should also include the examination of the roof deck from the underside for evidence of leaks, deteriorated decking, structural cracks, or movement and other deficiencies. Parapets and edgings should also be examined for evidence of cracking, deterioration and moisture infiltrations. In addition tothe scheduled semiannual inspections, roof inspections should also be conducted whenever any of the following conditions occur: a. Exposure of the roof to severe weather conditions, such as strong winds, hail or long continued heavy rain. Examine the roof for severely ponded conditions, broken pavers, displaced pavers or gravel, debris, and any other damage to the building components that may allow moisture to infiltrate. The membrane should also be examined in areas where damage has been identified due to punctures, tears or loose fasteners. b. After repair or replacement of rooftop equipment, and at any other time when the roof may become exposed to activities of other trades where damages may occur. Examine the rooffor spills, debris, sharp objects, membrane punctures, and possible delamination on adhered roofing systems caused by constant foot traffic. Your Hickman Representative can provide recommendations for the correction of any damage found. LEAK INVESTIGATION 1. On metal decks, it is important to identify the direction of the deck flutes and deck slope. Moisture may infiltrate through the roofing system and migrate in the lower flutes of the deck and leak inside the building in Iow areas. the leak location and frequency. PAGE 2 Begin leak investigations by conducting a thorough, visual inspection ofthe general location on the roof where leaks have been detected inside the building. a. Inspect areas Of ponded water (if the roof is dry at the time of investigation, areas of ponded water can be identified by accumulated residue on the membrane). b. Examine lower areas of the roof for moisture beneath the membrane (soft insulation can be detected when walking on the membrane). c. Check areas around mechanical rooftop equipment, drains, gravel stops, curbs, expansion joints, pipes, etc. to identify cuts, punctures or damage. d. Explore the condition of metal flashing (i.e., edging, coping, expansion joint covers, etc.). NOTE: On Ballasted Roofing Systems, if leaks are a result of punctures or small cuts in the membrane, it will be necessary to remove the ballast using a push broom prior to further investigation. EMERGENCY REPAIRS (TEMPORARY REPAIRS) Repairs should only be performed by qualified workers. Emergency repairs required to provide immediate protection from water infiltration may be performed by the building owner; however, permanent repairs must be completed by a Hickman Accepted Roofing Applicator when weather conditions permit. 1. Wet Surface Emergency Repairs a. Remove as much water as possible. b. Apply W. P. Hickman Temp-Seal or Wet Patch to the membranes where a leak is suspected. 2. Dry Surface Emergency Repairs a. Clean the membrane of dirt and debris. b. Apply W. P. Hickman's ARM and Hickman Glass Mesh to the damaged area. 3. Proper repairs must be completed by a Hickman Accepted Roofing Applicator. contacted by the building owner to coordinate long-term repairs. Note: Hickman Systems shall be In the event of a leak in the roofing system or flashing assembly, the Building Owner must notify Hickman in writing within ten (10) days after discovery of the leak. HANDLING WARRANTED REPAIRS When repairs are necessary on warranted roof projects, W. P. Hickman Systems relies on their local Field Representative to determine what repair is required and if it is within the coverage of the Hickman warranty. With few exceptions, Hickman will request that the permanent repair be completed by the original Accepted Roofing Applicator who installed the project. 2. The Hickman Accepted Roofing Applicator or building owner must contact Hickman's Field Representative prior to performing warranted repairs on warranted roof projects. HANDLING NON-WARRANTED REPAIRS If, as determined by W. P. Hickman Systems' representative, the required correction involves items outside the coverage of the Hickman Guarantee, the customer is required to have corrections completed within a reasonable time by a Hickman accepted contractor, at the Owner's expense, in order to resume coverage under the Hickman Guarantee. PAGE 3 WIND DISTURBANCE The Membrane System Warranties offer a wind protection up to 74 mph peak gust wind speed which is measured at 10 meters above ground level. When wind disturbance is encountered, W. P. Hickman Systems, Inc. must be contacted to investigate the causes and to offer alternate enhancements. Depending on the type of roofing system, the wind impact will vary. 1. Adhered Roofing Systems If membrane delamination, insulation facet delamination or loss of insulation securement occurs, W. P. Hickman Systems must be contacted to evaluate the situation and determine the causes. 2. Ballasted Roofing Systems Minor scouring of the gravel may occur, especially at the corners and some perimeter areas. If pavers were used, displacement may be observed. Minor scouring of gravel and displacement of pavers should be corrected by adding additional gravel to the bare spots of the membrane; however, when major scouring is observed, Hickman should be contacted. NOTE: Major scouring may contribute to displacement of insulation beneath the membrane and possible loss of membrane securement. b. Deteriorated or broken pavers should be replaced with an equally weighted paver. If interlocking pavers were used, the paver manufacturer must be consulted concerning a recommended repair. 3. Mechanically Fastened Roofing Systems Correction, repairs or enhancements to Mechanically Fastened Roofing Systems will greatly vary depending on original roof design, wind zone, building height and any large openings in the building. W. P. Hickman Systems, Inc. must be contacted to evaluate the situation and determine a solution or enhancement. NOTE: When a wind disturbance is detected, Hickman Suggests the owner take immediate steps to add temporary ballast (i.e., sand bags, tires, etc.) to keep the affected area from expanding, even during lesser winds, and use emergency repairs to close any openings. At the same time, W. P. Hickman Systems, Inc. must be contacted, and it is recommended your insurance company be notified as well. Verbal notifications should be confirmed in writing. LOOSE WALKWAYS If loose walkways are observed, the walkway should be resecured with approved adhesives. NOTE: Walkways are a maintenance item and are not warranted by W. P. Hickman Systems, Inc. GUIDELINES FOR ADDING OR MODIFYING ROOFTOP EQUIPMENT Rooftop equipment changes on commercial, industrial or institutional facilities are not unusual. A prudent property owner or facility manager should consider the following important points when adding to or modifying rooftop equipment. 1. Warrantor requirements Our warranties will be "null and void" if changes or modifications are made to a roof system without written authorization. Therefore, an owner must provide written notice of proposed rooftop equipment modifications to W. P. Hickman Systems before construction begins. The notice verifies that the proposed modifications conform to the warrantor's specifications for construction details, methods and materials. These requirements can be obtained from W. P. Hickman Systems' Technical Services Department. PAGE 4 conditions. Some of these include support curbs and stands, prefabricated metal unit curbs, job-site fabricated wood unit curbs, sheet metal enclosures for service lines, stacks, pipes and pipe roller supports. We generally do not recommend using "sleepers" or pitch pockets (e.g., penetration pockets). Sleepers (e.g., 4 x [100- by 100-mm] treated lumber) are placed on a roof's surface, on top of which equipment is set. The equipment's weight may cause the roof insulation to compress, which could lead to membrane rupture. Additionally, the sleepers and equipment are not secured and offer no wind uplift resistance other than that which is provided by the unit's dead load. Pitch pockets are not the preferred penetration detail because the filler may shrink and cause water collection that eventually results in leaks. As a result, pitch pockets require frequent inspection, as well as maintenance. When there is no alternative, design improvements are available with nonshrink grout and rain collars to enhance a pitch pocket's performance. f. Afl equipment service lines should be accessible from the rooftop and aflow for disconnection or shut-off. g. Vibration dampers should be used as recommended by the equipment manufacturer. When using vibration dampers, positive securement of the equipment is required to provide the necessary wind uplift resistance. Ductwork should have a watertight seal. The methods used to connect and seal ductwork must accommodate the air pressure or vacuum within the ductwork, maintain a bond to the ductwork and allow the metal to move. When ductwork requires external insulation, a waterproofing jacket or membrane must be installed over the insulation. Building owners should choose an insulation and waterproofing combination that provides Iqng-term watertight performance. (Often, simplistic, Iow-cost solutions can be problematic.) In most cases, a roof membrane or second sheet-metal skin should be used to waterproof the insulation and ductwork-- a single-ply membrane with heat-welded seams often is a good choice. 5. Roof system protection Temporary protection of an existing roof system is critical to maintaining watertight integrity and long-term performance when construction activities must occur. Mechanical (e.g., foot traffic, punctures, heavy loads) or contaminant (e.g., paint, refrigerant, acids) damage can destroy a roof system. Temporary protection is an option; however, even the most elaborate types of protection cannot guard against excessive abuses and poor housekeeping practices. Because the type of temporary protection depends on several criteria, such as roof membrane type, insulation and expected abuses, Hickman must be consulted for specific recommendations. The following general guidelines should be noted: ao Plywood and oriented-strand board are the most common types of temporary protection. These panels help distribute loads while providing solid, durable working platforms; however, panels can cause damage, especially to single-ply membranes. The panels should not be dragged during placement because gouges and punctures may result. A layer of moisture-resistant insulation (e.g., extruded or expanded polystyrene insulation [EPS]) can be placed between the panel and some roof membrane systems for additional protection (not applicable over coal tar). When storing materials on a roof, membrane protection and even load distribution should be provided. Materials should not be stored on the roof system's surface for extended time periods. Doing so can compress the insulation, rupture or puncture the membrane, and retain moisture on the membrane. Hygroscopic materials should not be used as temporary protection, especially if the protection must remain for an extended time period. For example, rosin paper and cardboard may be excellent protection for keeping paint overspray off surfaces, but these materials will be damaged by moisture. Point loads, such as scaffolding, are best avoided unless the loads can be distributed across the roof system's surface. Ifa load is large, it may have to be transferred directly to the roof deck or supporting structure. Support legs or a framing system can be installed and flashed into the existing roof for watertight service. e. Construction debris must be removed on a regular basis. This decreases the risk of punctures to the roof membrane, overloading the structure and water retention. f. There should be protection (e.g., a membrane walkway pad) at all access locations, such as ladders and PAGE 6 doorways. Installation of temporary walkways also should be considered if rooftop traffic is frequent, concentrated to a particular area or restricted to the same pathway. All personnel should check shoes or boots for sharp objects before stepping offtemporary protection and onto the roof membrane. Conclusion By carefully planning for, documenting and implementing modifications to a roof system, a building owner can protect his investment while accommodating the facility's, needs.
