Greeley Roofing: Article About All About Flashing
If you take a look at your roof or the roofs in your neighborhood, you may notice bits of metal wrapped around the base of chimneys or layered against intersecting roof sections. These bits of metal form a protective barrier between the roof's aesthetic top layer and the rest of the roofing material underneath, and they're known as flashing. Flashing helps prevent water from getting into the tiny spaces on your roof, and it's a vital part of any good Greeley roofing installation. In order to keep your roof protected, you need to make sure the flashing on your roof is adequately maintained.
Flashing is made from corrosive-resistant sheet metal and consists of two parts: base flashing and cap flashing. The base flashing is applied directly to the roof, and the cap flashing overlaps it on the object or portion of the roof that needs it. This two-fold method of installation ensures that water runs off your roof and away from your home. Contractors use nails to secure the metal in place.
Like other parts of your roofing material, flashing needs to be maintained regularly in order to ensure its durability. While you're on a ladder checking your roof twice annually, pay special attention to the flashing. Note whether there are signs that water or fallen objects have damaged the material in any way. Signs of damage include bent portions of the cap flashing and holes.

You can repair simple holes using caulk or a special sealant available at hardware stores, but you should be wary of DIY repairs when it comes to flashing. If you notice holes around the nails that secure the flashing, contact a professional quickly. Loose nails indicate a larger problem with the roofing system. In fact, most problems with flashing also indicate something serious because flashing is the first line of defense against water intrusion.
You may be wondering if you even need flashing. The debate rages on among homeowners and contractors alike over the necessity of flashing. After all, weatherproofing material layered underneath tiling or asphalt shingles ought to provide enough protection against the elements. With recent upgrades in ice and water shields, some contractors choose to use a felt underlayment to save on the total cost of a roofing job.
The fact remains that flashing adds an unparalleled level of protection, and you really need it installed if you want to safeguard your home against water damage. Think about the construction of your roof. Even if you own a single-story home, chances are that you have a skylight, chimney or vent pipe protruding from the roof's surface. Whenever there's a change in direction on your roof or an area that intersects with another structure, you'll need flashing.
