Roof flashing is the best way to prevent roof leakages. It acts as a sealant between the roof joints thus keeping the water from getting to the underlayment. Note that, some areas of your walls and roof are susceptible to water damage or leakage.
For instance, if you have a dormer wall with its roof surface, skylight perimeters, roof valleys, chimney and any other roof projections. Anywhere with heavy water runoff or where the surfaces meet, roof flashing can be used to prevent any leakages.

Types Of Roof Flashing
Note that, flashing is created through soldering. Here are some of the different types of roof flashing commonly used in Columbia Heights, MN.
• Chimney – Flashing will be used at the base of the chimney in multiple parts. It can be placed at the bottom while on the sides there will be step flashing. On the top, there is saddle flashing. Also, cap flashing can be used around the chimney to lap over the edges of the rest of the flashings in use.
• Vertical Wall Or Slopped Roof – Here, step flashing will be used. Drip edges will prevent any water from getting underneath the roof especially around the eaves.
• Skylights – Integral flashing is used together with step flashing on the base of the skylights. Saddle flashing is used on the top and on the sides of the skylights.
Leaks mostly occur where pipes penetrate the surface s as well as the flashings found in roof valleys. Here, asphalt roofing cement will be used as a sealant. Use vent pipe flashing to prevent leaking around the areas with pipes, especially where the pipes are penetrating the roof surface.
What Happens When The Flashing Is Damaged?
Since flashing is added to the most vulnerable areas, it’s likely going to be damaged at one time or the other. Flashing can be damaged in several ways such as warping, cracking or being completely torn. On the other hand, it’s likely going to be damaged because of poor repairs, improper installation, exposure to weather elements and age.
The best way to determine if there is any damage to the flashing is to check if there is a leak coming from the vulnerable areas in your roof or home. If present, you can contact an experienced roofer to help you fix it immediately.
