The Dilemma: Re-Roofing or Roof Replacement?

When your roof is showing signs of wear and tear, you’re faced with a critical decision: should you opt for re-roofing or go for a complete roof replacement? This is a question that many homeowners grapple with, and the answer isn’t always straightforward. In this article, we delve into the nuances of both options to help you make an informed decision.

Can You Place New Shingles Over Old Ones?

Yes, you can place new shingles over old ones, but this is only advisable if your existing roof is made of asphalt or composition shingles. The condition of your current roof also plays a significant role. If your roof is in decent shape with only minor issues, re-roofing could be a viable option. However, if your roof is severely damaged, simply adding a new layer of shingles won’t suffice. Also, it’s crucial not to mix materials; for example, don’t place asphalt shingles over wood.

The Advantages of Re-Roofing


Re-roofing is generally less expensive than a complete roof replacement. If budget constraints are a concern, this could be an ideal solution.

Aesthetic Appeal

When done correctly, a re-roof can look just as good as a brand-new roof. The type of your existing roof will influence the choice of re-roofing materials.


A well-executed re-roof can last as long as a new roof, provided it’s done according to industry standards.


Re-roofing is quicker than a full roof replacement, allowing you to focus on other things, like spending a day at the zoo.

Additional Protection

A new layer of shingles can offer extra protection against the elements, assuming your old roof is in good condition.

When Re-Roofing Isn’t the Best Option

If your roof is more than 20 years old and shows significant signs of damage, re-roofing may not be the best course of action. In such cases, a complete roof replacement is often the more prudent choice.
