In the field of roof waterproofing, high-quality materials and skilled workmanship can not only make a difference but actually save time and money. The KÖSTER BAUCHEMIE AG has been a worldwide leading manufacturer of high-quality roofing and waterproofing membranes for 30 years. With a high commitment to quality, KÖSTER stands behinds its products and customers. That’s why KÖSTER offers a comprehensive guarantee program for its TPO membranes: Premium and Premium Plus.
Upon conclusion of a warranty agreement, with KÖSTER Premium your roof is protected depending on the membrane thickness for a period of 10 to 20 years. Additionally, labor and material costs are insured during installation as well as any costs for the replacement of damaged parts included in the roofing system (such as wet insulation). With KÖSTER Premium Plus, protection goes a significant step further: any consequential damages incurred and resulting financial losses are covered by an extended product liability insurance policy from the leading German insurance company, Allianz AG.
Warranties must be requested individually for each construction project in advance. Warranties are valid for a period of 10, 15, or 20 years. The policyholder only pays a one-time surcharge per m² of roof area during the entire warranty period. A warranty claim exists provided leakage in KÖSTER TPO membranes have resulted from material failure.
