A Comparison Between Roof Replacement and Re-Roofing

One of your building's most necessary elements is your roof. It is also the most vulnerable because of its constant exposure to the elements. It can endure most of the damages thrown at it, but it does have its limitations. When that time comes, choosing between re-roofing vs. roof replacement might be confusing, so here's a comparison to help you:

What is Re-roofing?

Re-roofing entails placing a set of new shingles over an existing set of shingles. Because it's a one-time thing, re-roofing is not a choice if you already possess two roofing layers in place. Since there is no need to remove the old roof, you can total a re-roofing considerably quicker and at a lower cost than a total roof replacement.

When is Re-roofing a Good Idea?

Re-roofing is an attractive option for owners with a roof towards the end of its useful life but is still in good condition. There might be slight difficulties or leakage, but there will be no severe water damage, wet or missing shingles, or excessive moss or mold growth. It's also a better option if you're replacing just a portion and not the entire roof.

Before re-roof, you need to have roof hatches to conduct the work. It will make things more convenient for you or your chosen contractor to have this installation because it provides an entry point to the area. If your roof is extensive, consider installing equipment roof hatches as you may need them in the process.

When is Re-Roofing Not a Good Idea?

Roof replacement isn't often the top choice. You can't find a way to ensure what the roof deck appears like because you're not removing the present shingles. While you can identify most issues before it rips the shingles off, there is occasionally decay or sagging behind the shingles that are not noticeable. When you build a new layer on top of an existing one, you're merely masking the issue rather than addressing it.

If only a fraction of your roof needs replacement, re-roofing may pose problems since you will have a segment of the top that is thicker than the rest. It might indicate that they don't line up correctly at the ridge cap, which could be noticeable.

Re-roofing is only possible if only a single layer of shingles is on the roof. While you could try to re-roof more than that on your own or hire a roofer to do the task, there's a possibility that you could not drive the nails deeply enough into the several layers of shingles to keep the latest layer in position. With more shingles layers, it's tougher to see what's underneath them, which may result in defects going unnoticed.

What is Roof Replacement?

A roof replacement encompasses removing the entirety of the roof down to the deck and replacing it with new shingles and felt paper. Even if re-roofing is not viable, you can do a roof replacement regardless of the number of shingle layers present on the roof. It's also more costly than re-roofing due to the additional effort required.

The Right Time for a Roof Replacement?

You can do roof replacements whenever you choose. However, you must do it within reasons like when the roof has more than a layer of shingles or if you suspect that the roof deck has more issues. A roof replacement is also the ideal option if the entire roof or shingles are in terrible condition, as it enables you to deal with all problems rather than merely covering it up.

Takeaway

If you need a new roof right now and saving money is a priority, you might want to install it yourself, but it is not a good recommendation. You'll need to conduct extensive study familiarizing yourself with the applicable construction codes, underlayment regulations, and roofing standards in your area. Hiring an expert could save you all of these hassles. Depending on your location, you may even have to get a permit.
