PROTECTING YOUR DURO-LAST ROOFING INVESTMENT We are pleased that you have chosen the Duro- Last roofing system for your application. The Duro- Last roofing system is a superior system that is backed by the strength and quality assurance of a leader in roofing technology. The Duro-Last warranty is an agreement between the building owner and Duro-Last Roofing, Inc. assigning responsibility to each. (Note: Duro-Last has a contract with your Duro-Last installer for the first 2-years of this warranty for all warranted repairs.) It will be to your advantage to plan and implement a roof maintenance program in order to prevent needless and unwarranted damage to your roofing system. A simple and basic maintenance program will protect your investment by eliminating many costly repairs, as well as damages to your building. You have purchased a strong and durable roofing system, however, some inexpensive and routine maintenance is recommended to protect your investment. If a leak should appear: 1. Duro-Last should be notified immediately by calling 1-800-248-0280. This will help in getting a prompt response. 2. In addition, Duro-Last must be notified in writing within 30-days in order to meet the terms and conditions of the warranty. 3. Care should be exercised when reporting leaks. The Duro-Last warranty does not provide for leak investigation if the claim is not attributable to Duro-Last or is not covered within the warranty terms. 4. You should inspect the leak area to verify the leak is indeed covered by the terms and conditions of the warranty. 5. If a Duro-Last dealer / contractor or Duro-Last representative is dispatched to investigate a leak and determines it is due to conditions outside the limits of the warranty, you will be invoiced for the cost of the investigation. 6. Please note: Reporting a leak to an authorized Duro-Last dealer / contractor or enlisting a dealer / contractor s service for investigation and repair does not constitute notification to Duro-Last, as required by the warranty. Many rooftop damages are the result of individuals or companies performing maintenance or construction on your building during or after the roofing installation. These persons should be held liable for any damages to your roofing system. Should emergency repairs be required, the building owner should take action with or without the approval of Duro-Last to prevent water entry into the roofing system and/or building interior. However, you must also notify Duro- Last of the repair no later than the next working day. Emergency repairs must be reasonably controlled in the judgment of Duro-Last to have not significantly increased the scope of the necessary permanent repairs. SAFETY MEASURES It is the responsibility of the building owner and contractor to protect people on the roof. Consult OSHA and local safety agencies for safety guidelines. The well-being of these persons should be your number one priority. Rooftop repair and construction can be a dangerous occupation, and requires strict compliance with the recommended safety procedures. WHY REGULAR INSPECTION AND MAINTENANCE? Roofs are constantly under attack from weather, structural movement and stresses, and chemicals present in the atmosphere. While normal aging will occur on all roofs, small problems stemming from neglect, abuse, contamination, error, or accident can result in extensive, costly repairs or premature failure of the roofing system, if not detected and addressed. A regular program of inspection and repair detects minor problems before they become serious, avoiding interruptions of internal functions within the building, and most importantly, protects the owners investment by adding years to the life of the roof. www.duro-last.com 3 of 14 800-248-0280
A MAINTENANCE PROGRAM The first item in a maintenance program is the scheduling and responsibility of roof inspections. At least two inspections should be made every year. Ideally, inspections should take place in the spring to check on damage that may have occurred in the winter, so repairs can be scheduled during summer months. The second inspection should be in the fall. Make sure the roof is in good condition for the coming winter. Inspections should also be made following any occurrences that might affect the roof; e.g., storms, construction activities and/or fires. The other major item in a maintenance program is the inspections. All components of the roofing system should be closely inspected and a record made of any/all signs of deterioration, unusual traffic patterns, poor drainage, accumulated debris, displacement or loss of ballast, or other conditions. SEALANTS All pitch pan fillers, caulking, and sealants must be evaluated during regular inspections. Sealants are a major item in any maintenance program due to the extreme stresses created in these areas. Sealants are susceptible to cracking, pulling away from walls or other surfaces, and splitting. Sealant replacement should take place at the first sign of deterioration. DRAINAGE Whenever possible, the roof design or structure should provide for positive drainage to eliminate ponding water. Duro-Last guarantees that ponding water will have no adverse effects on its waterproofing membranes; however, the weight of ponding water may deflect the decking and framing members causing damage to the structure and the roofing system. Ponding water can be defined as an accumulation of water remaining in an area 48 hours after a rainstorm. Proper roof drainage is a very important item in a maintenance program. Drains should be clear, and all debris that may clog a drain should be removed during each inspection. Every drain should have a clean leaf grate present to prevent clogging of the drainpipes. Tennis balls, baseballs, soda pop cans, etc. on the roof should be removed from the roofing surface to eliminate the possibility of roof drain clogs. Roof inspections in the late fall should also include the removal of leaves. A clean industrial broom can be used to sweep leaves from drainage path(s). Another way of removing leaves and other debris, as well as being able to observe drainage patterns and activity, is to wash the roof. Washing removes the dirt from the roof surface, which is helpful for reviewing typical membrane wear during the roof inspection. PARAPET WALLS Parapet walls should be inspected for deteriorating coping, cracked or open mortar joints or other signs of degradation. Degradation of the parapet wall can lead to water penetration into the structure, which is not only harmful to a structure but may cause the failure of parts of the roofing system. Insulation, decking, framing members, and the fasteners in a mechanically fastened roofing system may all be adversely affected by moisture penetration. BUILDING STRUCTURE The condition of the structure, both interior and exterior, should be visually checked during regular scheduled inspections to detect a variety of possible defects. Defects within a structure can affect the roofing system because of the interaction(s) between the structure and the roofing system. BUILDING STRUCTURE (INTERIOR) The interior can be viewed by removing ceiling tiles if a drop ceiling is present. The walls should be viewed for settling, cracking, or movement. The decking should not be rusted if metal, or deteriorating if wood. Any water stains that become evident after the installation of the Duro-Last roofing system will require research to determine the entry point of the water/moisture. A concrete deck should be checked for spalling, cracking, or distortion of the deck to reveal possible structural defects. Any or all of these items can affect the roofing system because of the stresses revealed. Contact Duro-Last for evaluation when encountering any of these items. www.duro-last.com 4 of 14 800-248-0280
BUILDING STRUCTURE (EXTERIOR) The exterior of the structure should be inspected for open mortar joints, poor laps in siding, concrete spalling, loose fascia or general degradation. Any or all of these items will allow water and moisture penetration which may affect the longevity of the roofing system and the structure itself. New (evident after installation of the Duro-Last roofing system) water stains on exterior walls may indicate that the coping or other terminations are leaking. ROOF TIE-INS Areas of tie-in should be thoroughly inspected for any signs of failure. Roof System tie-ins have two dissimilar products in contact, creating an area of stress. The sealants and other items, in these areas, should be reviewed for cracking, splitting, or gaps. Degradation of the other roofing system may have direct impact on the performance of the Duro-Last Roofing system. Any questions regarding the life of a tie-in should be directed to Duro-Last for warranty considerations. AIR CONDITIONING UNITS Air conditioners should be checked to insure that the doors/access panels are properly fastened in place, and the drainage lines are functioning properly. Clogged drain lines and missing access panels can, if not installed or working, create leakage into the structure. BALLAST AGGREGATE (1 1/2-inch River Washed Stone / Aggregate) Note: Any ballast of up to a 1 1/2-inch River Washed Stone / Aggregate will receive a 10- year warranty only. For the installation of this ballast system, contact the Engineering Services department and ask for the ballast installation specification (not found in this manual). For the installation of a paver system, refer to the Duro-Last Paver System section found in this specification manual. GOOD HOUSEKEEPING The final area of inspection is on the general appearance of the roof and the surface conditions of the membrane. As discussed, debris, poor drainage, or ponding can directly affect the roofing system. An effective maintenance program will address these items and prevent damage to the roofing system. Care must be taken to ensure that sharp debris is removed. Debris can be broken bottles, sheet metal, sticks, nails, screws, or other miscellaneous items. The most common areas to find debris of this nature are around air conditioning equipment, other penetrations, elevation changes or areas of access. REPAIRING PROCEDURES CLEAN-UP AND REPAIR After the Duro-Last Roofing System has been installed, the authorized Duro-Last dealer / contractor shall remove all foreign matter, rubbish, and scrap material from the roof. When cleaning the membrane surface, a non-sudsing powdered cleanser, i.e.: Spic-N-Span or other powdered cleaner recommended by Duro-Last, shall be used. The following procedures shall be followed when a repair is required on the Duro-Last System. Specific situations and conditions will dictate which of the proper procedures to use. CLEANING SOILED ROOFS FOR REPAIR When the roofing material is relatively clean, perform the following steps: 1. Clean deck material thoroughly with an approved cleanser using a clean absorbent cloth; rinse area thoroughly with a second cloth and clean water; Repeat these steps until the area is clean. Use a hand-held hot air welder to blow area completely dry. 2. Cut a patch of Duro-Last membrane neat and square with rounded corners. Patch must be a minimum 2" (50 mm) larger in all directions than the area to be patched. Minimum patch size is 4" x 4" (.1 m x.1 m). Patch must be installed parallel to tabs on roof. www.duro-last.com 5 of 14 800-248-0280
3. Using a hand-held hot air welder and a silicone hand roller, weld patch to the deck membrane around its entire perimeter creating no less than a 1-1/2" (38 mm) wide weld. With tack puller, check integrity of weld. No glues or mastics are allowed. REPAIRING SEVERELY SOILED ROOF When the roofing material is so soiled it can no longer be properly cleaned, perform the following steps: 1. Cut out damaged area of roof to be repaired. Make sure cut edges are cleanly cut to allow patch to be installed under deck membrane. 2. Cut a patch of Duro-Last membrane neat and square with rounded corners. Patch must be a minimum three (3) inches (76 mm) larger in all directions than the cutout. A Minimum 6" x 6" (.15 m x.15 m) size patch must be installed parallel to tabs on roofs. 3. Slip the patch through cutout and position it under deck membrane so cutout is centered over center of patch. Using a hand-held hot air welder and hand silicone roller, weld clean bottom side of deck membrane to clean topside of patch. Continue welding around entire perimeter of cutout creating not less than a 1-1/2" (38 mm) weld. With tack puller, check integrity of weld. No glues or mastics are allowed. patch. Continue welding around entire perimeter of cutout creating not less than a 1-1/2" (38 mm) weld. With tack puller, check integrity of weld. No glues or mastics are allowed. EXTREME EMERGENCY SITUATIONS (TEMPORARY REPAIR ONLY) Under extreme emergency situations, a patch of Duro-Last may be adhered over the damaged area using a vinyl cement or caulk. The damaged area must be cleaned and dry before the above procedures. Directions on the vinyl cement or caulk should be followed. This is not a permanent patch and should be properly repaired as early as possible. REPAIRING MEMBRANE HAVING CONTACT WITH ASPHALT ROOFING PRODUCTS Duro-Last membrane having asphalt-based roofing products must be cut out and replaced with new membrane. 1. Cut out damaged area of roof to be repaired. Make sure cut edges are cleanly cut to allow patch to be installed under deck membrane. 2.
