Reroofing vs. Roof Replacement: Which Is Best for Your Atlanta Home?

When fixing your roof, you have two primary options: reroofing and roof replacement. Which option should you choose? As the go-to contractor for premium roof replacement in Atlanta, Rock House Roofing delves deeper into the reroofing vs. roof replacement debate.  

What Is Reroofing?  

Reroofing involves placing a second layer of shingles on top of an existing roof. While not always possible, reroofing can rejuvenate your roof, prevent leaks, and help you save on replacement costs.   

The installation team won’t have to remove the existing roof, cutting time, material, and labor costs. Since the process involves covering the existing roof with an additional layer, people often refer to the process as “recovering.”

Reroofing offers a cost-effective way to extend your roof’s lifespan without spending a fortune on an entirely new one.

What Is a Roof Replacement?  

If a roof already has a second layer, the 2018 International Building Code 1511.3.1.1 prohibits adding a third layer. Similarly, you can’t reroof a water-soaked or significantly damaged roof. If a roof inspection reveals your roof has compromised structural integrity, opt for a roof replacement instead.  

Unlike reroofing, roof replacement involves tearing out the existing roof and replacing it entirely. The roofing team removes the waterproofing and underlayment layers and replaces them with new material. This allows roofing contractors to inspect the decking as well.  

If the decking is intact, the roofer applies new underlayment and shingles. Otherwise, they repair the decking before installing the new roof. You can always replace a roof, and roofing experts recommend replacement when your roof has more than a few minor issues.  

While a roofing material’s projected lifespan matters when determining when to replace your roof, stay alert for the following signs of a roof in need of replacement:  

  • Leaking or water damage  
  • Dark spots  
  • Visible holes  
  • Missing shingles  
  • Mold, rot, or moisture  
  • Sagging in the roof deck  

How To Decide Between Reroofing vs. Roof Replacement  

Several factors come into play when deciding between reroofing and replacing your roof, such as the following:

Cost  

Cost matters when considering reroofing or a roof replacement. However, it shouldn’t be the only deciding factor. Reroofing costs significantly less than a full roof replacement because you don’t need to remove the old roofing material.   

With a roof replacement, you’ll spend more but enjoy peace of mind. Depending on the lifespan of the new roofing material, you may not need to worry about roofing issues for several decades.  

Material Used   

Most reroofing situations involve roofing material that lays flat, such as asphalt shingles. You typically can’t cover up metal roofing, clay tiles, or slate with anything because nailing into them would cause irreparable damage. Therefore, not all roofing materials lend themselves to reroofing.  

The Roof’s Condition  

Reroofing may prove cost effective and prudent if you have a structurally sound roof with no soggy or missing shingles, major leaks, storm damage, or extensive water damage.   

Any reputable Atlanta roofing company would recommend a roof replacement if your roof has incurred water damage to the deck, has a missing or damaged protective underlayment, or has many missing shingles.   

Reroofing a severely damaged roof masks the underlying issue, making it harder to address the problem and setting the stage for significant challenges down the road.  

Structure  

Reroofing requires a sound structure. Significant roof damage due to exposure to the elements rules out the possibility of reroofing your Atlanta property. In such cases, you must replace the roof.  

Timing  

Reroofing works best when your roof is nearing the end of its lifespan before it starts to degrade. If your roof has plenty of life left but displays signs of damage, consider replacing it. Remember, you can only reroof once in a roof’s entire lifespan as part of its routine maintenance.  

Why Hire a Professional for Reroofing or Roof Replacement?  

Any roof-related work falls outside the scope of a DIY enthusiast or amateur handyman. Roofing requires special knowledge, safety equipment, tools, and experience. A skilled roofer will use the right products and techniques to ensure your roof stays in top shape for a long time.
