Asphalt Shingles for Your Roof

Asphalt Shingle Roof

The current popularity of asphalt shingles in resident property roofing projects is actually owed to a number of reasons. Throughout many regions of the world, this form of roofing shingle is relatively inexpensive due to certain geographical factors, and that’s why it’s a top choice for Hawaii roofing. The height of a building, slope of its roof, and other property elements make asphalt shingles the primary choice for many roofers. It also doesn’t hurt that these shingles come in a variety of styles and colors and are easy to install, simple to repair, and quite durable (some of these shingles have achieved Class IV hail ratings).

Types of Asphalt Shingle

There are two main types of asphalt shingles: glass fiber/fiber glass and organic. While most people know about glass fiber shingles, some may not be familiar with organic type. This shingle is created by saturating paper with asphalt so as to make a felt material that is waterproof. After being coated with a top layer of adhesive asphalt and embedded with ceramic granules, the shingle is complete and is now a product that contains 40% more asphalt per square than glass fiber. These shingles always weigh substantially more than glass fiber and as a result are more durable and resistant to high winds.

Length of Asphalt Shingle Roofing

Glass fiber shingles are not without their own benefits, however. As shingles made with glass fiber matting and coated with asphalt, they are excellent for roofing reinforcement. The use of “filler” in the creation process also causes the shingle to become waterproof. In both organic and glass fiber shingles, the ceramic granules used help to protect the shingles from damage from constant exposure to sunlight. The sun’s UV rays are very damaging to asphalt and will cause it to deteriorate prematurely. This is also one of the same reasons that gravel is used on built-up roofs.

So which type is better? Although each shingle has its own advantages and drawbacks, most building contractors and property owners tend to favor glass fiber shingles. This can be attributed to their low cost and how easy they are to manufacture as well as personal preference.

The Lifespan of an Asphalt Shingle

Asphalt shingles are durable, but their average lifespan varies depending on the environment. Warmer climates, such as those found in Hawaii, tend to shorten the lifespan of asphalt roofing due to constant exposure to heat and UV light. Another factor that affects shingle roofs is improper attic ventilation. Well-done ventilation work can make asphalt shingles more durable and reduce the frequency of necessary roof repair, saving you money.

Regarding Shingle Warranties

Shingle manufacturers provide product warranties against manufacturing defects ranging from twenty (20) to forty (50) years and beyond. These warranties cover defects such as thermal splitting, some cases of granule loss, cupping, and curling. It is very important that you ask for and receive a copy of the manufacturer’s written material warranty before making a decision on whose material you’d like to use. Warranties are generally for materials only. Labor is rarely included so if your roof materials fail, you’ll have to pay a roofer to install the new shingles. Warranties rarely, if ever, cover what are known as “incidental and consequential” damages resulting from material failure. “Incidental and consequential” damage as are those that occur to the interior of the building. If anything on the inside of the building gets damaged, you or your insurance company will have to pay for it. Warranties are also commonly prorated and non-transferable. This means that if you have twenty year shingles and they fail after ten years, you’ll be reimbursed for half the cost of the materials. Non-transferable means that if or when you sell your house, the warranty will be voided.

Some shingle manufacturers are offering NDL (No Dollar Limit) warranties for added costs of around 4.5 cents to 6.5 cents per square foot. These warranties may or may not cover all damages and labor costs.

Shingle manufacturers will not warrant their products against “Acts of God or Nature” such as hurricanes, hail storms, severe winds usually in excess of 50 mph, tornadoes, earthquakes, etc. Nor will shingle manufacturers honor their material warranty if the products are improperly installed, there is improper roof ventilation, there is equipment installation or structural changes after roof completion, or there is heavy foot traffic on or over the roof.

For specific warranty information, ask your contractor to provide a sample warranty of the materials he installs. Contact us today for more information.
