What Properly Installed Flashing Means to Your Roof?

When you think of your roof, you probably only think about the main component: The shingles or the tiles that enhance the look of your home and that protect it from rain and the elements. Yet your Peoria roof is actually composed of numerous elements working together. If one of those elements fails, the whole system can fail.

Flashing is one of the most important components of your roof, but it isn’t as well-known as tile or shingle. A qualified Peoria roofing contractor will understand the importance of flashing and will take special care in installing it. The wrong installation can lead to expensive roof repair later.

Here’s what you need to know:

What is Flashing?

Flashing is material that covers the joints on your roof. These are the odd spaces that shingle or tile doesn’t quite cover, such as area where the chimney meets the roof or where pipes or vents come out of the roof. It is also installed where the roof meets other walls, such as on the second story or the attic. Roof shingles and tile can’t form a tight seal against these elements, so flashing is necessary to keep a water-tight roof.

Flashing is usually made of galvanized steel or aluminum. Sheet lead and copper can also be used. It has to be thin and sturdy, so that it can slide under other roofing materials and can stand up to the elements.

How Flashing Is Installed

Flashing is installed under shingle or tile. It is nailed directly to the roof decking and glued or nailed to the chimney, side wall or other elements that meet up with the roof. The metal is bent to shape so that it lies flat against both the roof and the object that intersects with the roof. This is typically an “L” shape, but it can take other shapes.

Roofing cement is used to seal up the holes from the nails, and the roofing material is installed over the flashing.

Issues from Improperly Installed Flashing

Improperly installed flashing can leave your roof vulnerable to leaks. If the flashing doesn’t form a tight seal, water can seep under the tiles or shingles. This can cause leaks or it can cause the roofing material to come loose.

Water that seeps in through the flashing can travel far from its source. You may have leaks several feet from the flashing, which allows the water damage to your home to grow.
