Materials for commercial roof flashing

Rubber, aluminium, and lead, all of which are used to plug any holes in the rooftop, are the most widely used types of commercial roof flashing materials.

Sheet metal gets cut on the roofing location and then shaped before being put. Rubber membranes can be applied by pouring or spraying.

Although lead sheets are among the most flexible roofing materials, handling them is challenging because they are quite heavy.

It’s crucial to keep in mind that certain materials may decay faster than expected if they are placed together with other dissimilar metals and materials. A knowledgeable roofing contractor will take this into account when designing or repairing your roof to avoid any issues.

Aluminium – Aluminum is a great flashing option for treating wood or adding a new aspect to concrete roofing. It is affordable, easy to create, and long-lasting. When placed close to, or alongside alkaline substances like treated wood or concrete, aluminium flashing will corrode.

Copper and its lead-coated counterpart – While aluminium can be bent and moulded rather easily, it is harder to bend copper and mould it into shape. It is, nevertheless, a great deal more resilient than aluminium. During installation, copper flashing is frequently used to connect sensor connections, wiring, and pipes for solar panels.

Galvanized Steel – Although it is relatively affordable, galvanized steel is not as durable or strong as other options.

Lead – Because of its exceptional flexibility and durability, lead is a preferred material for roofing, and you find many masons using it to create their chimney flashing. Using lead flashing is often a safe option provided it is used properly. However, there can be health risks when it isn’t properly handled and managed.

Plastic and rubber – Although they are more frequently employed as caulking, these materials are perfect for repelling water when used as flashing.

Polyvinyl chloride (PVC) and thermoplastic polyolefin (TPO)- PVC and TPO roofing systems are both well-liked, and both offer incredibly strong and long-spanning protection.

Roofing felt is a less long-lasting substitute for other materials that are made of roofing felt that has been wet with asphalt.
