It takes a strong roof to protect your home from the elements. But after several years, this structure will start to experience wear and tear that could put your property in jeopardy. If small repairs aren’t enough to address these issues, you may need to hire a roofer to re-roof or replace the structure altogether. Use the following guide to learn the difference between re-roofing and roof replacement and when to consider each.  

What’s the Difference?

During re-roofing, a contractor installs a new layer of shingles—known as an overlay—on the existing structure. By contrast, full replacement involves tearing off all of the shingles, repairing the underlayment, and installing new shingles.

Compared to full replacement, re-roofing is the more affordable and less labor-intensive option. However, there are times when an overlay may not deliver the results you need.

What to Consider When Deciding Between Re-Roofing and Full Replacement

Age

Standard asphalt shingles can provide quality coverage for an average of 20 years. If your materials are compromised and close to meeting their life expectancy, it’s more economical in the long run to replace the entire structure.

If the structure has been around for fewer than 15 years, installing a new overlay may be the simplest solution.  

Current Problems

When the structural components underneath the shingles are intact, re-roofing is usually feasible. This new overlay will update the look and offer another barrier to help prevent leaks.

If damage extends beyond the decking, a roofer will likely need to repair the underlying structure, which is more feasible during a full replacement.

Previous Overlays  

A new overlay can only be installed once during a roof’s lifetime. If you’ve already invested in re-roofing, building codes dictate that you can’t add a third layer of shingles. In these situations, a complete replacement will provide the best solution.
