When the contractor delivered the sad news that my roof needed replacing, that led to a discussion of material choices. I was surprised to hear that metal roofing was an option. Sure, it was fine for commercial buildings, but a home? My contractor told me that metal is used for homes more than people realize. The panels can be designed to look like just about any type of roofing you can imagine. After looking at some samples and finding out about the long life of metal roofs, I decided to give it a try. Fifteen years later, my roof is still in great shape. If you are facing a roof replacement in the near future, let me tell you more about metal roofing. I'm betting that you'll decide this solution is right for your home.
A well-built roof is made up of many parts, all of which increase its degree of water resistance. Yet many people still labor under the misbelief that shingles are the only thing needed to keep a home dry. If you would like to improve your knowledge of the materials and strategies used in roofing today, read on. This article will introduce you to two protective elements installed below the shingles.
This is a T-shaped piece of sheet metal that is attached with nails to the decking at the edge of the roof. There it serves three important purposes. First, it prevents so-called blow-under leaks. Such leaks are common during rain storms accompanied by high winds. Should the direction of such winds be right, they will blow the rainwater up below the shingles at the edge of the roof--unless a drip edge is installed.
Second, a drip edge acts as a support for the shingles at the edge of the roof. Otherwise, these shingles simply hang off into open air. This makes them especially vulnerable to the weight of ice in wintertime. Finally, the drip edge helps to guide rainwater down into the gutter, rather than letting it curl around the edge of the shingles and run down the vulnerable wall of your home. Without this vital component, your gutters simply won't be able do their intended job.
Ice And Water Shield
An ice and water shield consists of a three foot wide waterproof strip. It is attached along the edge of a roof so as to just overlap the top face of the drip edge. One side of an ice and water shield is coated in an extremely strong adhesive. Once pressed into place, this keeps the shield firmly in position without the need for mechanical fasteners.
The purpose of an ice and water shield is to prevent leaks caused by ice dams in the winter. Because such dams tend to cause areas of ponded water, they often result in water leaking around the roofing nails and into the attic, where costly forms of damage ensue. Ice and water shields prevent this by sealing your roofing nails with a waterproof barrier.
In many parts of the country, local building codes mandate the installation of ice and water shields. Homes that do not comply with such features may not be eligible for insurance benefits should leaks become a problem down the line. Protect yourself--and your home--by researching the particular building codes in your area.
