Leakage is one of the most common issues found in the roofing installation. Alderon weather seal is specially designed to address this problem.
Alderon weather seal is equipped with the washer that is perfectly fit onto the crest of Alderon roof. It is made from the same material as Alderon roof as to ensure it will harmoniously expand and shrink at the same time with Alderon roof during the noon and the night time. The cap that comes with Alderon Weather Seal will ensure the galvanized bolt last longer against the weather.
