Best Roof Measuring Tools 

The first step in your roof buying process is to budget! The only way to do that is by figuring out how large your roof is. Luckily, it’s as easy as a few clicks of a mouse now that we have all of the technology behind satellite imaging and aerial measurement. The best type of roof measurement tool for Atlanta is typically just to buy an Eagleview report.

This will typically cost anywhere from $30-$100 depending on the size of your property. Alternatively, you can request a free estimate from one of many local roofing contractors and let them know ahead of time that you’d like to have an Eagleview included.

While there are other softwares and measuring tools available in the market, the roofing industry has generally decided that Eagleview is the benchmark for accurate aerial imaging. That is why we’ve listed it here as the best type of roof measurement tool for homeowners in Atlanta.

Other options include: Aerial Reports, Inc. and Roof Scope

Once you have your aerial measurements back, you’re ready to whip out your calculator and crunch some numbers. Your measurement report will have a total square footage on it. It will also have a suggested waste percentage. You will need to take the total square footage and multiply it by (1+waste percentage). This results in your total square footage needed to complete your new roof. Simply take that and multiply it by the prices we’ll talk about below to figure out just how much you need to budget for your roof replacement.

Best Type of Roof Decking for Atlanta, Georgia

What is roof decking?

Roof decking is the substrate level of your roof, which provides the structure for the remainder of the roof to be installed on-top of. Generally speaking, there are two main types of roof decking used in Atlanta. 

For the latest pricing on all decking, you’ll need to check your local HomeDepot due to the fact that pricing is constantly changing.

Plank Roof Decking

Plank decking was used in Atlanta home construction for years and years, but has quite a few deficiencies when it comes to longevity and integrity of the roof. This type of decking is typically some form of “1-by” boards. That is, 1”x6”, 1”x8”, 1”x10”, or some combination of these. This type of decking is measured in linear feet, as opposed to the square footage calculation we got from our aerial measurements.

Sheet Roof Decking

Sheet decking is a more modern material used for roof decking and boasts added longevity and integrity over plank decking. This type of decking is typically some form of sheets. The most common sheet sizes are 8’ by 4’. This type of decking is measured in square footage, which makes it easy to approximate from our aerial measurements. 

It is important to note that not all “Sheet” decking is the same. There are two main types of sheet decking: OSB and Plywood. If budget is not an issue, we recommend going for the plywood decking option, as it provides a more sound decking structure for installation of the other roof components.

When does roof decking need to be replaced?

The decking on your roof will only need replacement in the case that it is rotten, or out of building code. Unfortunately, many houses with plank decking are no longer up to code in Atlanta and MUST be replaced when the existing roof is removed. See the section below titled “Roof Decking Requirements in Atlanta, Georgia” for more information.

This is probably the only aspect of the roof budgeting process that is impossible to forecast with 100% accuracy. Your roofing contractor will typically specify a cost for roof decking replacement on a per-foot basis.

How much roof decking should I budget in my roof replacement?

If your existing roof is installed on plank decking, we recommend budgeting for a FULL replacement of the decking on the home. However, if the existing roof is installed on sheathing (OSB or Plywood sheets) then you can typically get away with just a couple of pieces. 

As a general rule of thumb, budget 1 sheet per 1000 square feet of roof space from the aerial measurement report.

How much does roof decking cost?

Roof decking is a commodity, because the wood can be used in many different ways in construction. Because of this, you’ll need to check with your local building supply store in order to get the most up to date information. 

We typically recommend either HomeDeport, Lowes, or Ace Hardware for a ballpark estimate. You can also just google “OSB sheet price HomeDepot” in order to get pricing.

Roof Decking Requirements in Atlanta, Georgia

As of 2021, any plank decking that has greater than a ⅛” gap between the planks MUST be replaced with sheathing. This requirement has been imposed by the shingle manufacturers, which means that your roof warranty will be void if careful attention is not paid throughout the installation process. If your contractor is pitching you on leaving the existing plank decking, just be sure that you have proof it holds up to these standards.

Best Type of Roof Underlayment for Atlanta, Georgia

What is Roof Underlayment?

If you want to have the best type of roof in Atlanta, this is a SUPER important aspect of the roof that you need to understand. Roofing underlayment is the final waterproofing layer of your roof. It is typically composed over either synthetic material, felt, or asphalt. Some brands will even combine these materials into hybrids.

In addition to the water-proofing aspects, it also provides an additional layer of insulation for the roof structure and your home. Depending on budget, you can even upgrade your roof to have special premium insulating underlayment.

Types of Roof Underlayment

The three materials we discussed above, synthetic, asphalt, and felt, makeup the 3 main types of roof underlayment in Atlanta. For the sake of simplicity, we’ll just leave this topic with a simple recommendation…synthetic felt is the way to go!

What are Roof Shingles?

We’re finally to the part of the roof that you are likely the most comfortable with and aware of. This is the part of the roof that you can see from the ground. It is the hard outer covering that provides durability for the roofing system for years to come. Shingles are simply a mixture of asphalt, tar, and fiberglass. Three major manufacturers in the industry: Owen’s Corning, GAF, and Certainteed. While some contractors will try to convince you that one product is better than the other, the standard lines of shingles are all VERY similar. 

**While we typically recommend Certainteed shingles, that is only because of our status as a top-tier contractor for them. We fully believe in and support the installation of any of these shingles.
