		Congratulations on your purchase of a Cavco Roofing Membrane! Your roof is a valuable asset and as such should be properly maintained. All roofs and roofing systems require periodic maintenance to perform as designed and to keep your Limited Warranty in full force and effect. 1.  The roof should be inspected at least twice yearly (in the Spring and Fall), and after any severe storms. Record maintenance procedures as they occur. Log all access times and parties working on the roof. 2.  Proper maintenance and good roofing practice requires that ponded water (defined as standing .water on the roof forty-eight [48] hours after it stops raining) not be allowed on the roof. Roofs should have slope to drain and all drain areas must remain clean. Bag and remove all debris from the roof since such debris can be quickly swept into drains by rain. This will allow for proper water run-off and avoid overloading the roof with ponded water. 3.  The roofing membrane should not be exposed to acids, solvents, greases, oil, fats, chemicals and the like. If the roofing membrane is subject to contact with any such materials, contact Cavco immediately. 4.  The roofing membrane is designed to be a waterproofing membrane. If there is to be roof traffic for any reason, contact your Licensed Applicator before proceeding for the installation of approved protective walkways. 5.  Some roofing membranes require maintenance of the surface of the membrane in order to perform as designed: a) The application of an approved liquid coating, such as Aluminum Roof Coating or Acrylic Coating System for Asphalt to smooth surfaced APP membranes provides additional protection from the environment. If this coating is not applied as part of the initial roofing installation, it should be applied within the first five years after the roof is installed to help protect the membrane from surface cracking inherent in such asphalt products. In addition, this coating should be maintained as needed to recover any areas of the coating that have blistered, peeled or worn through. b) Granule surfaced APP and SBS membranes do not normally require surface maintenance other than periodic inspection for contaminants (see item 3), cuts or punctures. If areas of granular loss are discovered during inspection, new granules should be broadcast into hot asphalt or emulsion to protect the surface of the membrane. 6.  All counter flashing, metal work, drains, skylights, equipment curb and supports, and any other rooftop accessories functioning in conjunction with the roofing membrane must be properly maintained at all times. 7.  If any additional equipment is to be installed on your roof (e.g. HVAC units, TV antennas, etc.), contact Cavco Roofing, in writing, for approval before proceeding. 8.  Should there be an addition to the building, requiring tie-in to the existing roofing membrane, contact Cavco Roofing before proceeding to ensure the tie-in is in accordance with specifications. 1.  Check for the obvious: clogged roof drains, loose counter flashings, broken skylights, open grills or vents, broken water pipes. 2.  Note conditions resulting in leakage. Heavy or light rain, wind direction, temperature and time of day that the leak occurs are all important clues to tracing roof leaks. Note whether the leak stops shortly after each rain or continues to drip until the roof is dry. If you are prepared with the facts, .the diagnosis and repair of the leak can proceed more rapidly. 3.  Contact Cavco for proper repair of the leak. Cavco Roofing feels that the preceding guidelines will assist you, the building owner, in maintaining your building for many years. Remember, your building is an investment. To maximize your return on this investment, appropriate care is essential. Manhattan, NY 11201
