With the rise in popularity of producing solar energy, homeowners are starting to consider going solar when it’s time for a roof replacement. This can be a great idea because using your roof to produce solar energy can be a solid investment.

But the truth is, everyone isn’t going to be able to afford to invest in solar. That’s why it’s important to know how much a roof replacement is going to cost using the new GAF Timberline Solar Energy Singles.  Before deciding if it’s right for your home.

Unfortunately, roofing contractors like to keep their numbers under lock and key. That is until you offer to invite them to your home to do an inspection. We disagree with that.

Our family at RoofCrafters Roofing has been helping homeowners make their roof replacement decisions for nearly 3 decades. Because of this, we’ll help you determine if the GAF solar shingle roof will be a great investment and fit your budget.

In this article you’ll learn:

  • The 5 main factors that’ll impact the cost
  • The average cost of a Timberline Solar ES roof
  • The benefits of producing solar energy

By the end of the article, hopefully, you’ll have all the answers you need to decide if the solar shingles will be a great investment for you.

 

5 factors that impact the cost of a GAF Solar Shingle Roof.

 

It would be impossible for us to give you an exact price without knowing all of the many factors used to calculate the costs.

The 5 main factors that’ll impact the costs to produce solar energy are:

  1. The square footage of your roof.

  2. The average annual electricity consumption.

  3. The amount of sun-facing slopes on your roof.

  4. The complexity of your roof replacement project.

  5. The incentives available for going solar.

 

1. The square footage of your roof.

 

There are several factors that go into a roof replacement. The size of your roof is one of the many factors and will also have one of the greatest impacts on a a solar roof investment. A solar roof replacement requires purchasing specially designed asphalt shingles. The new GAF Solar HD asphalt shingles are almost 2 inches larger than the standard architectural shingles. Yes, this means your entire roof has to be replaced. We can't just add the solar shingles to your roof.

The new GAF Timberline Solar HD shingles are designed to be compatible with the GAF Timberline Solar Energy producing shingles. This requires purchasing the correct amount of the Timberline Solar Energy Shingles to power your house. Which leads us to our next factor, energy consumption. 

 

2. What is your average annual household energy consumption?

Your electricity provider or utility company typical measures usage in kilowatt-hours or kWh. (kWh = kilowatt-hour) One kWh is one kilowatt generated for one hour. Let’s say you use a 40-watt light bulb for five hours, you’ll have used 200 watt hours or 0.2 kWH of electricity. 

We all use different amounts of energy. Depending on how energy efficient your home is and how conscious you are about your energy usage. The good news is you can reduce both and in turn save yourself bundles money. It really matters how much electricity you consume annually.  Once we know how many KW’s you need we can effectively calculate the size of the solar system needed to power your home. The less energy you consume the smaller solar system needed.

3. How many sun-facing roof slopes are on your home?

 

We use one of many tools to determine the amount of sun on your roof. The amount of great sun-facing slopes will also have an impact on how many arrays of solar energy shingles will be required. Optimal sun-facing roof slopes are typically the east and south facing roof slopes.

Having roof slopes that are shaded may require compensation. Which means installing more arrays of solar shingles on less optimal slopes. Compensation is needed sometimes. We need to produce enough electricity to power your home based on your yearly energy consumptions. Once this is determined the next main factor that impacts cost is the difficulty of your roof. 

4. The complexity of your roof replacement will impact the cost.

Is your roof steep? The steepness of your roof pitch will have a major impact on calculating the final cost of your solar investment. Because the safety and set-up takes longer. And the roofers are not able to work as fast. Slower installation times increase the labor cost on any home improvement project. 

 

We view investing into the new integrated solar energy shingles as doing two home improvement project in one. New roof and new solar system, all in one. Keep in mind, once the solar roof is installed the electricians will be required to get on the roof to connect all the wiring to make your new system run. If your roof is steep or difficult to access their labor portion of the installation will also increase.  Difficulty or complexity will impact the cost.

The good news is that incentives available may be able to offset these cost as well as your new roof.

5. What incentives are available for using your roof to produce energy? 

 

Financial incentives take many forms. The incentives available are often what help reduce the initial investment. Thus making it much easier to get a return on the investment in a shorter period of time. Our federal and state governments have incentives in place to help homeowners afford to produce clean energy.  

Here is a list of the most popular solar incentives:

  • Federal Solar Tax Credit
  • State Tax Credits
  • Net Metering
  • Local Solar Incentives
  • Sales Tax Exempt
  • Property Tax Exempt
  • Production Incentives
  • Cash Incentives

 

Incentives will help reduce the cost and in many cases offset the cost of the roof replacement. Thus making the two home improvement projects in one a fairly easy decision.

As you can see, there are many factors that'll impact the cost of a new solar energy roof. It would be nearly impossible for us to provide you with an exact cost without knowing all of the factors.  So to be fair, we will provide you with the average cost of a Timberline Solar roof installed on a fairy simple roof of a 2000 to 2500 square foot house.  Fair?

Also very important, a house that needs a solar system to produce 7 KW of electricity.  Just like the square footage of the house we've selected is average, most houses will range between needing 5 KW and 9 KW of electricity usage . So a 7 KW solar system is average.

 You can expect the average cost of a solar roof system to be between $35,000 and $40,000. That’s before deducting any incentives previously mentioned. By applying the 26% federal tax incentive alone, it'd reduce the average cost to between $25,900 and $29,600.

Keep in mind,  that the average price we’re providing is for a complete solar roof system. This includes a complete roof replacement. Which means installing the new Timberline Solar HD asphalt shingles and installing enough of the new Timberline Energy Shingles to produce 7 KW of electricity. Two home improvement projects in one.

If you are you concerned about the rising cost of electricity. This may be a great investment for you. There's no doubt in our minds that the cost of electricity will continue to rise. Producing your own clean energy and decreasing your reliance on the utility company may be worth looking into.
