3 Flashing Installation Mistakes That Put Your Roof at Risk

Flashings – those unassuming strips of metal that are attached to your roof may seem unimportant, but they actually play a vital role in protecting your home from leaks. If they fail or get damaged, it may seem like a nice little project to do yourself over the weekend – after all, they’re just thin strips of metal. How hard can it be to install? Unfortunately, many homeowners get this idea and end up regretting it. Here are three reasons why you should call in an expert to install your roof’s flashings for you.

1. Mistakes With Valley Flashing

The valley of your roof is where plenty of water is diverted, which is why installing flashing in this critical area should be done flawlessly. Professional roofers often use the woven or W-shaped flashing for valleys, but even then, you can run into problems if you don’t know what you’re doing. 

2. Not Installing Sidewall Flashing Correctly

If you have a dormer or wall butting up against your roof, sidewall flashing will need to be installed to properly seal the joint. Experts use step-flashing, a rectangular piece of flashing that is bent at a 90-degree angle, to waterproof it. One of the common DIY mistakes homeowners make is not installing it in overlapping layers resulting in a weak seal.

3. Not Installing a Drip Edge

A drip edge is metal flashing installed at the edges of the roof to keep water from getting underneath your roofing components. Some DIYers neglect this step completely or install them incorrectly resulting in damage to the roof, fascia, soffits and siding.
