If you had to repair or replace your roof in the past, you probably already heard the term “roof flashing.” Flashing is a type of roofing product that is placed at the valleys or the places where the chimney meets the roof in order to prevent leaking. An essentially sealing product, flashing is very important to both the health of your roof and to the protection of your home from water damage.
The reason why roof flashing is so important is because rainwater tends to gather around the valleys of the roof, where it can even pool and end up seeping through to the underlayment, decking and attic. If your roof doesn’t have waterproof underlayment then there’s a big chance that the interior structure of the roof, the attic and possibly even your interior walls will end up being affected by water damage.
With properly installed flashing, this issue is no longer a relevant threat. Unless the flashing ends up being damaged or worn out over time, it will provide a basically waterproof seal that will protect your roof and home from rainwater. The result could be that your home will be better protected and your roof will also retain its long lifespan without the need for expensive Dexter MI roofing repairs or replacement jobs.
