Metal Roof Repairs are easy to do if you the know-how
Most people use tar, caulking, and silver coating to try and stop leaks on a metal roof. It is very important to make sure that the products that are used, will not make the problem worse. Watch this video above to see how tar almost destroyed a metal roof.
Why do metal roofs leak?
Most metal roofs start to leak at the seams of two overlaying panels. With the initial installation, a gasket or sealant is placed between the joining panels. This gasket or caulking deteriorates over time due to the extensive heat from the sun. The contraction and expansion also wear away or brakes the seal. In conjunction with the seal giving, the fasteners above the seams also wear out and cause leaks.
When these fasteners leak, water will then collect behind the gasket or sealant. This is why it always appears that the seams are leaking.
