Should I Re-Roof or Replace My Roof

Re-roofing has a long history. The thought at the time was that adding a new layer of shingles over an old one would further waterproof the shingles. And, in the process, if you didn’t have too many layers of shingles already on your roof, you wouldn’t have to pay to have the old shingles removed. 

Despite the fact that some roofing contractors may offer re-roofing, this technique has fallen out of favor for many reasons. Let’s look into the reason that re-roofing isn’t the best thing for your home.

What is Re-Roofing?

Re-roofing or overlayment is the process of adding a second (or third!) layer of shingles over your current shingled roof. This process is commonly performed on asphalt shingles. However, some clients who are interested in metal roofs may have the same question about layering a metal roof over shingles. 

What is a Roof Replacement?

A typical roof replacement is when you remove all the shingles and materials down to the roofing decking, replace any damaged plywood, and then proceed to build up the roof as the manufacturer intended, using the proper leak barrier, roof deck protection, starter shingles, and other roofing system components.

Re-Roofing Pros

There are only a few pros about re-roofing. Re-roofing will cover up your roof with new shingles. It may or may not fix current leaks. Re-roofing will save you money in the short term since you won’t be paying someone to remove the shingles. 

Re-Roofing Cons

Reroofing has a long history. The thought was that adding a new layer of shingles over an old one would just further waterproof the shingles. And, in the process, if you didn’t have too many layers of shingles under there, you wouldn’t have to pay to have the old shingles removed. 

Today, there are several problems with this logic. First, homes are built for the weight of one roof. Increasing that weight can cause structural problems within your home. 

Second, today’s shingles aren’t just shingles. They’re part of an entire roofing system that’s meant to keep your roof watertight.  Layering on a new layer of shingles won’t replace that roofing system, meaning that any aging or deterioration of the roofing system will still exist.

The warranty on your shingles only applies if the contractor uses the roofing system that goes with it. 

Re-Roofing Or Roof Replacement

Re-roofing is a thing of the past, whereas roof replacement gives you all the advantages of a healthy roof, a strong home, and a long warranty. 

You should be suspicious of any contractor who recommends re-roofing your roof. While the price may seem tempting, there are very few advantages.
