Flashing is a very important part of your roof. Its the permanent solution to preventing water from getting in around chimneys, walls , and dormers. We see everyday where roofers and homeowners try to use roofing cement as a replacement for flashing and it just don’t work. Step flashing on chimneys,walls,and dormers is so important in preventing them from leaking. We have seen many times where step flashing had been installed but the roof still leaks due to nail hole in the flashing or improper installation.
