Flashings are thin pieces of metal found in the roofing system, usually made of aluminum and galvanized steel. They’re one of the least interesting parts of the roof, but their rather characterless appearance doesn’t mean that they’re not extremely important.
To understand why they are key to reducing your roof repair costs, AnyWeather Roofing talks about what you need to know about them:
The number one reason why pieces of flashing exist is to weatherize your roof’s vulnerable sections. They cover seams and gaps that otherwise would let rainwater and snowmelt into your home. With them in place, these weak areas become water-resistant. And since your roof is only as tough as its softest underbelly, the rest of the system benefits from them.
In addition to protecting your roof against the elements, any GAF Master Elite® roofer would attest that they contribute to curb appeal, too. When they’re color-coordinated with adjacent shingles, they help create a clean look. Experienced providers of roofing services agree that these relatively unglamorous accessories add the finishing touches.
Flashing pieces are not made equal. Each one has to feature a unique design to unfailingly serve its designated area.
Drip edges (arguably the most important) feature angled metal strips nailed over and beneath the underlayment on the sides and at the eaves, respectively. They play a vital role in drainage, directing the water over the eaves and into the gutters instead of allowing them to build up.
When it comes to sloped roofs meeting vertical walls, step flashing features an L shape to fit in and seal the intersection. On the other hand, base flashing is applied on upturned edges of the roof. Valley flashing is generally longer and wider to neatly protect the place where the slopes meet and water collects.
Causes of Failure
Fkashing pieces aren’t impervious to the elements. The sealant used to seal them corrodes over time, creating tiny gaps that are big enough for water to infiltrate and start significant damage.
Although they’re incredibly durable, the metals used for flashing age, too. One of the worst practices inexperienced and unreliable roofers are guilty of is recycling salvageable pieces. When re-applied or not replaced during a roofing project, old ones would fail more quickly than their newer counterparts would.
