Hip, Cool, Metal? Choosing a New Roof or Auditioning a Band?

Roofs come in all shapes and sizes. There are hip roofs, flat roofs, gabled roofs and more. Roofs also come in a variety of materials from wood to metal and in more color options than ever before. Cool and green roofs are increasingly popular. Replacing your old roof is your opportunity to upgrade and update your home to improve its value and curb appeal. When replacing your roof, you may want to add new safety or cosmetic features. Sometimes you may need to replace or repair structural elements. When the old roof is removed and out of the way, you have the perfect opportunity to make improvements to your home’s ventilation, insulation and wind mitigation. As you begin the process of choosing a new roof, you’ll probably have a few questions.

When you call Callaghan Roofing to discuss replacing your roof, we’ll help you find the answers you need. We’ll make arrangements to come to your home and inspect your existing roof. Then together with you, we’ll discuss your options and how to ensure that your new roof meets all of your needs. In the meantime, here are e few tips about roofs to get you started.


What’s a hip roof and do I have one?

A roof can be as simple as a flat top or it may combine several different shapes. Valley, dormers and additions all add to the complexity of your roof’s shape. Some of the most common roofs you’ll see are gabled, with or without dormers, and hip roofs.

A gabled roof has two flat planes or roof surfaces that come together at a gable or angle at the top. This type of roof design leaves either end of the roof faced with a triangle-shaped portion of the house’s exterior wall. A hip roof caps the roof end with an additional flat plain. These roofs may still have a top ridge, but they will also have side “seams” where the separate panels of the roof come together. Because it has more flat surfaces to absorb and redistribute energy, a hip roof offers more defense against hurricane winds. However, gabled roofs are still common and popular. Whichever type of roof you have, our expert team can conduct a full wind mitigation inspection of your home and suggest any structural changes necessary ensure that your roof is as secure as possible once installed. Callaghan Roofing teams regularly install roofs of all shapes and sizes, so no matter what type of roof you have we’ve got you covered.


What type of material should I choose?

Your choice of roofing material will depend on your goals, taste and budget. Most roofs are either covered with asphalt shingles or metal panels. Other materials include clay tiles, wooden shakes or slate. Slate and clay tiles provide a lot of curb appeal and durability but are significantly more expensive than other choices. Wooden shakes will give your house a distinctive look but at the cost of durability. For homeowners in Tallahassee, we recommend that you replace your old roof with a new metal or asphalt roof.

Recent advancements in the quality of both metal and asphalt roofing materials mean that a new roof in either material should provide you with greater durability and energy efficiency than the roof you are replacing. Also, the selection of colors and designs available in both materials increase every year. Replacing your old roof with either of these materials, will greatly increase your home’s value and curb appeal and allow you to stay within your budget. Finally, with so many colors and styles available, there’s no reason for you not to install an Energy Star rated roof. Whether you choose asphalt or metal, these cool roofs will reduce your utility costs and may even qualify you for a rebate.


How much does the average roof replacement cost?

The cost of reroofing a 2,000 square foot home is usually between $8,000 and $12,000, depending on the roofing material you choose. While metal roofing costs slightly more than asphalt shingle to purchase and install, a metal roof may last up to 50 years. In comparison, the best asphalt shingles last up to only 30 years. If your roof is over 12 to 15 years old, you may see immediate energy savings once your new roof is installed. You’ll also be improving your home’s weather protection. Besides, replacing your roof still costs less than a three-day Grateful Dead concert ticket and your new roof will last a lot longer.

Your Home’s Cool Roof: More Than Just Looks

If you have done any recent research on how to save on home cooling cost, you may have come across cool roofing as one of your options.

But what is a cool roof? Well, yeah, they look good, but that’s not what makes them cool.

What makes my roof cool?

A cool roof is one that through a combination of features actually helps keep your house cooler. To be truly cool, a roof should have properties that improve its solar reflectance and its emissivity.

Whoa? It should do what?

It should reflect and emit.

Beyond just keeping your house safe and covered, a cool roof reflects sunlight (solar reflectance) and actively releases the heat that it absorbs (emissivity).

Solar Reflectance- Bouncing Back Solar Energy

According to the government’s Energy Star website, reflectivity is the most important factor in deciding how cool your roof is. You may have seen advice about keeping physically cool during the summer that mentions wearing light-colored clothes. And anyone who has gone outside on a sunny day in their favorite navy blue T-shirt knows that color choice matters!

Light colors reflect solar energy; dark colors absorb it. This same principle is true whether you are applying it to clothing, vehicle upholstery, or roofs. A cool roof uses color and reflective elements to throw the sun’s heat right back at it instead of absorbing it into your home. The U.S. government’s Energy Saver website says that a dark colored roof can reach temperatures of 150 degrees F on a summer day. Ouch! That same roof in a lighter color can be 50 degrees F cooler.


Cool roofs can be flat or sloped and are made from a variety of different materials. In fact, if you have a flat roof, you can even cover it with a light colored paint to achieve a cool roof effect.

If you are looking for a new energy-efficient, cool roof for your residence or business here in sunny Tallahassee, then a modern metal roof like the ones we install are a great choice. Metal roofs are naturally reflective, and a metal roof will give your building a modern, attractive look. You’ll improve your building’s efficiency and its curb appeal.


Emissivity- Release the Heat

Even a roof that is designed to reflect most of the sun’s energy will still absorb some heat during a sunny day. The ability of your roof to release that heat back into the atmosphere is the second feature that a cool roof employs to help you keep your cool. Most roofs have an emissivity rating of 85%, with a 100% rating being the best at releasing heat.

Unpainted metal roofs don’t always score as well as shingled ones when considering emissivity alone. However, because of their high reflectivity scores, a metal roof can still be a cool roof. An unpainted metal roof may not be very emissive but treated with the proper coating that same roof can score an 83% on the emissivity scale. When you combine metal’s reflective properties with this emissivity rating, you have an overall coolness factor that is hard to beat.

We have plenty of cool choices for you

Currently, Energy Star certification is assigned based on a roofing material’s solar reflectance value. Thousands of different roofing materials qualify for the Energy Star rating. You can choose from a variety of colors from burgundy or green to champagne gold or solar white. In addition to the cost and energy savings you’ll achieve when you choose an Energy Star certified cool roof for your home, there’s also still time to qualify for an Energy Star tax credit.Cool roof installation by Callaghan Roofing
