Guarantees


2.1 JM Approved Roofing Contractor

2.1.1 JM does not construct commercial/industrial roofs, nor do we own an interest in any firm that does. Thus, except under the terms of a JM Guarantee, we cannot be responsible for any roofing contractor’s workmanship.

2.1.2 We do maintain a list of contractors, called JM Approved Roofing Contractors, who are eligible to construct and to repair JM Guaranteed Roofs. THE NAME "APPROVED ROOFING CONTRACTOR" MERELY IDENTIFIES AN INDEPENDENT CONTRACTOR CONSIDERED ELIGIBLE TO APPLY FOR A JM ROOF GUARANTEE AND IN NO WAY DESIGNATES HIM AS AN AGENT FOR JM. JM ROOFING CONTRACTOR APPROVAL IS SPECIFIC TO THE ROOFING SYSTEM TYPE, I.E. BUR, SBS, APP AND SINGLE PLY NDL GUARANTEES ARE ONLY AVAILABLE THROUGH NDL DESIGNATED CONTRACTORS.

2.1.3 The Approved Roofing Contractor must notify JM in writing at least two weeks before starting any roof that requires a JM Roofing Systems Guarantee. Also, all other JM requirements must be met before a Guarantee will be issued.

2.2 JM Roofing System Guarantees

2.2.1 JM offers roof guarantees on the roofing systems published in this manual. Contact the local JM Roofing Systems representative for current guarantee information. Guarantees are limited to the 50 United States. Some restrictions or special requirements may apply on installations in Alaska and Hawaii. Contact a JM Technical Service Specialist for specific details about applications in these areas.

2.2.2 What is a Roof Guarantee? When a roofing system has been applied by a JM Approved Roofing Contractor, using JM materials, to the satisfaction of JM, and inspected by a JM representative, JM may issue a Roofing System Guarantee, delivered to the roofing contractor, for a charge based upon the fee schedule in effect when the application is received.

2.2.3 If a JM Roofing System Guarantee is to be issued, the JM Approved Roofing Contractor must obtain JM’s authorization before roofing application begins. For any job requiring asphalt, the Approved Roofing Contractor must provide JM with an Asphalt Confirmation Number indicating that the asphalt was properly registered with an approved source.

2.2.4 This guarantee assures the owner that JM, under the Roof Guarantee agreement, is responsible for keeping the roof in a watertight condition if leaks occur solely as a result of normal deterioration of the membrane or poor workmanship in applying JM materials or products. The obligation under the guarantee is limited to a specific number of years and, except in the case of No Dollar Limit Guarantees, a specified maximum monetary amount.

2.2.5 JM's obligation relates solely to JM materials as specified in the guarantee, supplied by JM and identified as JM’s on the original unopened packaging. Any damage to the JM roofing system caused by performance of, application of, or compatibility with materials not sold or supplied by JM is not covered under the terms of the guarantee. The Roofing Guarantee terminates if the term of the agreement expires, the maximum monetary amount of the liability is expended, or any alteration, additions, or repairs are made to the roof structure without JM’s prior written approval. The guarantee may be cancelled at any time by mutual consent of the building owner and JM.

2.2.6 JM will not be responsible for failure of the roof, or its roofing products, or for direct or consequential damage except as is expressly stated in the applicable guarantee. The roofing specification provided by JM is for guidance only and JM will not accept any responsibility for design or construction of the building.

2.2.7 The roof guarantee as issued by JM may provide the same type of coverage for the flashings if constructed in accordance with the published flashing specifications. Only those flashings which are constructed in accordance with JM specifications may be included in the guarantee. Gravel stops, curb details, or flashings incorporating metal not supplied by JM will be excluded from Guarantee coverage.

2.2.8 JM Expand-O-Flash and Presto Lock fascia and coping materials may be included in the guarantee, if installed according to JM published specifications, and factory-fabricated intersections are used. Flex-I-Drain and FP-10 One-Way Roof Vents may also be covered in the guarantee.

2.2.9 THE ROOF GUARANTEE PERIOD WILL COMMENCE ON THE DATE THE INSTALLATION OF THE ROOF IS COMPLETED.

2.2.10 What Does It Promise? The JM Roofing System Guarantee promises that for a defined period of time JM will pay for repairs to stop leaks resulting from natural deterioration of the membrane or poor workmanship in applying the guaranteed JM materials. The owner agrees to notify JM in writing of any defects or of any proposed changes to the roof, and also agrees to properly maintain the roof.

2.2.11 The JM Roof Guarantee covers leaks from the following causes except where caused by the exclusions set forth in Paragraph 2.2.12.

A.

Natural deterioration of the membrane.

B.

Natural deterioration of the membrane flashings.

C.

Natural deterioration of the roof insulation, if the insulation is supplied by JM.

D.

Blisters and bare spots.

E.

Fishmouths.

F.

Ridges.

G.

Splits, unless due to movement or failure of the substrate.

H.

Buckles and wrinkles.

I.

Workmanship in application of the roofing membrane.

J.

Workmanship in application of the membrane flashing.

K.

Workmanship in application of the roof insulation, if insulation is supplied by JM.

L.

Slippage of the roof membrane.

M.

Slippage of the flashing.

N.

Repairs due to local wind gusts less than, or equal to 63 mph (101 km/h), for BUR and modified bitumen systems.
