Lead Flashing for your roof has major advantages when it comes to sealing a roof against leaks. When a roof meets a vertical surface, such as the wall of a house, the joint between the two has to be sealed in some way. Perhaps the single best solution in the U.K. is Lead Flashing. The properties of lead make it an extremely favorable building material when it comes to sealing and water proofing.
Why Use Lead?
Lead is often used since it is one of the most durable metals that exists today. It can expand and contract with drastic changes in outdoor temperatures, which means that it can adapt to last longer given the conditions it's under. It's an absolutely perfect material to use on houses that are open to a variety of elements and different atmospheric temperatures. We know that being a London resident means that you will know all about this! During summer or an intense cold winter, there will be no need to call a repair man for repairs.
What Are it's Benefits?
Lead is a mouldable material and can be shaped into a variety of shapes to suit different types of flashing design. It can be adapted to fit along edges of different types of roof and it won't catch fire, which is important during an intense lightning storm. It's also sturdy enough to withstand these conditions which means that it will not buckle unless it is subjected to very high temperatures that are unrealistic in a habitable environment. The main purpose of using Lead Flashing is its capacity to be a strong barrier. Lead Flashing is resistant to atmospheric corrosion and that means that it will last longer than any other type of flashing. It's also sound resistant and will make your home ever so slightly quieter. It's radiation resistant, which is the most important factor to the structural integrity of a house. It is also a strongly recognized form of insulation that prevents heat from leaving your home.
This metal can be crafted to give the outer rim of a roof an aesthetically pleasant finish. Lead in flashing wears well and will be reduced from a shiny, natural state into a refined and professional looking material that adds character to the appearance of your home.
The Tech Specs
Flashing refers to thin pieces of impenetrable material that's been installed to your home in order to prevent the passage of water into it from a joint or as a part of weather resistant barriers.
Before sheet products became available for flashing, carpenters used their ingenuity to minimize water penetration such as angling roof shingles away from joints and building steps into the sides of a chimney to throw off water. Birch bark was also occasionally used as a type flashing material. The introduction of flashing materials decreased water penetration occurring at areas like chimneys, vent pipes, walls that abut roofs, and window and door openings which make buildings more durable and reduce interior mould problems.
Flashing can either remain exposed or stay concealed. Exposed flashing generally consists of sheet metal like lead, aluminium, copper, zinc alloy, stainless steel, terne, lead-coated copper, galvanized steel, or other architectural metals. Metal flashing should be combined with expansion joints on long stretches to prevent warping of the metal sheets and shouldn't stain or be stained by close by materials or react chemically with them.
Where Can I Use Lead Flashing?
The simple answer is on your roof. Roof flashing is placed around objects that protrude away from the base of a roof such as pipes and chimneys or the edges of other roofs. They're used to deflect water away from seams or joints and in valleys where the water tends to accumulate. Roof penetration flashings are used to waterproof supports, pipes, cables, and almost every type of roof protrusions.
A structure incorporating Lead Flashing has to be carefully engineered and constructed. It's important that the water is directed away from the structure and not directed to the inside. Flashing improperly installed will end up directing water right into your home.
