Creating A Better Home When you rely on your home to provide you with comfort and shelter, you can't take any risks with its ability to keep water outdoors where it belongs. Great roofing is instrumental in the fight against the elements, because it helps to create the kind of environment you need to keep your home and family safe. Unfortunately, there are many homes that don't have strong, reliable roofs, which can cause problems in the long run. On this website, check out excellent ways to spot roofing problems and resolve them quickly. After all, your home is your most valuable asset, so protect it now.



When it's time to replace your roof, you have two main options: a complete roof tear-off or a roof overlay. Both methods have their advantages and disadvantages, and the best choice depends on various factors such as the condition of your current roof, local building codes, and your budget. Here, you'll delve into the pros and cons of both approaches to help you make an informed decision.

Roof Tear-Off

A roof tear-off involves removing all existing shingles before installing new ones. Here are the pros and cons of this method:


Thorough Inspection: A tear-off allows for a thorough inspection of the underlying deck. Any hidden damage or rot can be identified and fixed before installing the new roof.

Longer Lifespan: Since the new roof is installed on a clean, flat surface, it tends to last longer than an overlay.

Better Resale Value: If you plan to sell your home in the future, a complete tear-off may increase its resale value as buyers often prefer homes with newer roofs.


Cost: A complete tear-off is more expensive than an overlay due to the extra labor and disposal costs.

Time-Consuming: This process takes longer as it involves removing the old roof, repairing any damage, and then installing the new roof.

Roof Overlay

A roof overlay, also known as re-roofing, involves laying new shingles over the existing ones. Here are the pros and cons of this method:

Cost Effective: An overlay is generally less expensive because it requires less labor and no disposal costs for old shingles.

Time-Saving: Since there's no need to remove the old roof, the process is quicker than a complete tear-off.


Shorter Lifespan: Overlays may not last as long as a completely new roof because any underlying problems are not addressed.

Potential for Undetected Damage: If there's damage or rot under the existing shingles, it won't be discovered and repaired during an overlay.

Weight Issues: Adding another layer of shingles adds weight to the roof, which some structures may not be able to support.

Before making a decision, it's essential to have a professional roofer inspect your roof. They can advise you on the best course of action based on the condition of your roof, local building codes, and your budget.

While a roof overlay might be tempting due to its lower cost and quicker installation time, a complete roof tear-off provides a longer-lasting solution and the opportunity to fix any hidden issues. However, the best choice depends on your specific circumstances, so always consult with a roofing professional before making a decision.
