Roof replacement is the process of tearing the old roof entirely and installing brand new materials afterwards.

Re-roofing is recommended for ones that are relatively new and decent looking. It is different from replacement as you don’t have to tear off the roof completely. In other words, it’s the process of saving some parts to lessen the costs and roofing wastes. It’s done by way of layering brand new shingles on top of existing parts. However, it could get tricky because re roofing a house is not meant for everyone. There are cases when it’s not possible anymore due to severe damages (like water damage) and aging. If your roofing’ health is still in good condition and there are no major damages, you can opt to undergo re-roofing. You must always seek professional advice before you come up with decisions involving re-roofing or replacement.

Replacement is done when your roofing’s life has reached the end of its line. There are many factors that could determine if your roof is indeed subject for replacement. One of them would be devastating weather conditions (like tornadoes and hurricanes) that directly wreak havoc on your roofing.

Signs That You Need a Re-roofing

Since you already know the difference between re roofing a house and replacement, it’s now time to dig deeper. If you’re unsure whether to get re-roofing or not, here are the most common signs observed in residential properties.

Recurring roofing issues is a sign that you might need something more extensive like re-roofing. If you are facing the same problems every so often, then you need to confirm with a professional roofer the best way to go.

Usually, you would need roof repair if there’s a certain part of your roofing that has been damaged. However, if a huge portion is already affected, it’s a different case already. You need re-roofing to fix the large areas of your roof.

Extremely Damaged Flashing

Flashings could also indicate that you need re-roofing services. If the flashing has rust, corrosions, or other obvious damages, you might need to re-roof to solve the issues. A damaged flashing can be the root cause of other problems like leakage.


It’s normal for a roof to age. If it’s nearing the end of its life expectancy, you don’t have to replace it right away. You can talk to a roofing expert for other options especially if it’s still in an acceptable state.

Exposed Roof Deck

Too many missing or loose shingles can expose the roof deck. This may lead to other roofing issues that are difficult to treat. Yes, it’s possible to replace missing shingles but if it gets damaged too often, you need a different strategy.

Mismatched Roofing Material

This is actually not a negative sign to watch out for. This is based on your personal preference. If you feel like the current system doesn’t match the theme or look of your property, you can opt to re-roof it. In some cases, a re-roofing happens if the existing materials do not thrive in the location’s weather condition.
