When Is It Time To Replace Your Roof?

Your roof is one of the most critical parts of your home and, certainly, the most functional when it comes to protecting your investment and loved ones. But like most things in life, roofs don’t last forever and will have to be replaced at some point in the future. This article will give you some tips to help you determine when it is time to replace your roof.

Mold, algae, or moss growth

Mold, algae, and moss growth are abnormal occurrences and indicate that moisture is not draining effectively from your roof. If you are able to address the drainage problem before damage occurs, it is possible to repair the roof instead of having to replace it. But if mold, algae, or moss growth is present, it is commonly a sign that replacement is required.

Roof leaks

In most situations, roof leaks are not noticed until water damage is seen inside the home, either on the walls, ceiling, or floor. Unfortunately, water damage is typically noticed after the roof has been leaking for some time and structural damage or internal mold growth has already occurred. As a result, roof leaks and interior water damage are signs that a total roof replacement is the necessary next step.

Sagging roof deck

Roofs can sag for various reasons, but the most common causes are internal water damage, deterioration of the support structure, or excessive weight on the roof. If your roof is sagging, it will likely need to be replaced. Typically, a sagging roof cannot be repaired. The good news is that a roof replacement will provide an opportunity to correct the issue that caused the roof to sag in the first place.

Visible signs of damage (wear and tear)

It’s essential to check for visible signs of wear and tear on the exterior of your roof because damage can indicate that there is a more serious problem. For example, cracked, curled, or missing shingles suggest that water damage has already occurred. On metal roofs, rust indicates that the protective coating has worn down and no longer works properly. Cracked, broken, or lifted tiles suggest that water and wind will eventually enter your home.

Increased energy usage

As roofs reach the end of their life, they can develop cracks or gaps that force the HVAC system to work overtime to keep the temperature comfortable inside your home. Insulation also wears out over time and can lose effectiveness. In either scenario, you will likely notice increased energy usage and a higher utility bill at the end of the month.


All roofs, no matter the material or quality of installation, wear out at some point. Shingle roofs typically perform well for 20-25 years, metal roofs for 35-70 years, tile for 50-100 years, and slate for 100 years and beyond. If your current roof is nearing the end of its expected lifespan, it is a good idea to start considering a replacement. If you wait until a problem exists and damage occurs, the roof replacement will likely be more expensive.
