This roof sealing strip is made of high-density closed-cell EVA foam, delivering excellent waterproof and moisture-proof performance. It can withstand extreme temperatures and harsh weather conditions, and will not crack, shrink or age even under exposure to intense sunlight, severe cold or heavy rainfall, ensuring long-lasting sealing effectiveness for roofs. The closed-cell structure of the strip features inherent rebound and compression properties, which can absorb vibrations and reduce noise levels. Meanwhile, it also provides thermal insulation benefits: in summer, it blocks external heat to reduce air conditioning loads; in winter, it retains indoor warmth to improve living comfort. Additionally, it can effectively resist strong wind impacts. Its shape can accurately fit the curved radian of most metal roofs. Combined with the included 2 rolls of 32.81 ft. premium butyl tape, it forms a double-seal structure that prevents the strip from shifting, and avoids water seepage even in the event of heavy rain or heavy snow. The sealing strip can be easily cut with scissors to fit various roof curves, edges and irregular parts. Installation requires no drilling or special tools, a single person can complete measurement, cutting and application, catering to both professional construction and DIY operation needs.
