Lead is widely used in roofing because it\u2019s an abundant and cost-effective materials that\u2019s water resistant and highly durable. However, prolonged period of exposure to the elements can affect the performance of lead. If your lead roofing is looking a little tired, you may be wondering when lead roofing should be replaced.<\/p>\n
The answer to your question, when should lead roofing be replaced, depends on the condition of the lead. Lead is well-known for outliving the life-span of buildings with little to no drop in performance after 200 years. However, the life-span of lead roofing can be reduced due to poor installation and fitment. As a general rule, if your lead roofing, cladding or flashings are in mostly good condition, your roof will require spot maintenance \u2013 the process of carrying out appropriate repairs. It\u2019s very rare to need a whole new lead roof, even in cases where the roof looks to be in a complete state of disrepair.<\/p>\n
Repairing lead roofing<\/strong><\/p>\n When repairing lead roofing, a roofer may use new lead sheet and carefully weld is over any split or cracks. This is a cost-effective way to repair tired lead. We and other roofers often find that the cause of lead roofing failure is due to the roll ends, which haven\u2019t been secured effectively. In this instance, a new pre-fabricated roll will need to be installed. Another common cause is an element out of our control \u2013 thermal movement. A good roofer will account for any linear movement upon installation, but bad roofers will not and cut corners.<\/p>\n The cost of repairing lead roofing depends on the scale of repairs needed. Spot lead roofing repairs will not cost you very much at all, however as to be expected, the larger the repairs needed the more it will cost you. The good news is that the larger the job, the less the raw materials (lead) will cost you. Labour will, however, remain the same, unless you can strike a deal with the roofing company you get in touch with.<\/p>\n
