The signs that your house needs a new roof are subtle and not easily noticed. As a result of this, roof damage happens over time without you being aware. Moreover, the roof is one of the most neglected parts of the house during maintenance. Neglecting your roof can invite major issues, some of which may require that you replace your roof with a new one.

5 Warning Signs That Your House Needs A New Roof

Replacing the roof of your house can be very expensive. However, not replacing it on time can lead to more severe issues and damage to your properties that will cost more to repair.
Below are 5 signs that you need to replace the roof of your house…

#1 Roof Leaks

roof leak

One of the most obvious signs that you need to replace the roof of your house is roof leaks. To inspect for roof leaks, regularly go into your attic. You should do this immediately after rainfall. Closely look for signs of water intrusion. This intrusion is commonly the source of most water leaks.
It is also crucial that you check the outside of your roof. Ice dams are formed when melted snow runs down the eaves of your roof and freezes again. The ice dam can block water from flowing off your roof freely. As a result, the blocked water can find its way under your shingles, and possibly make it into your home.
You may not have to replace your roof completely if the ice dam is confined to a particular area of your roof. Nevertheless, ensure that you call a professional to perform a thorough inspection of your roof. Fixing any issue with your roof is important to avoid more serious and costly repairs or replacements.

#2 Mold Or Mildew Growth

If you find mold or mildew growing on your ceilings or walls, it could be a sign of a condensation issue, a leaky roof or a simple plumbing issue. Before you go to repair it, ensure that your insulation is dry, your bathroom fixtures and plumbing lines are not leaking and your house is adequately ventilated. These signs can be easily corrected at a fraction of the cost it would be for a roof replacement.
You should be mindful of different growth types, including algae, mold, moss and mildew. Algae is a green and black organism that can eat away your shingles. It eventually results in roof rot. This problem is often caused by deposits of moisture on shakes and shingles. Algae is mostly found in gutters.
Unlike algae and moss which many consider natural flora and harmless, mold can cause health issues. Surfaces that can absorb water, like drywall and wood, are where mold most frequently grows. All of these growths have one thing in common: they all grow in wet settings. A roof with poor drainage will be particularly vulnerable to these problems in rainy areas.

#3 Roof Cracks


The wind is often the cause of cracked shingles. The most practical solution when the cracks are limited to a few shingles is to replace them. However, a tell-tale sign that you need to replace the roof of your house is if the crack is randomly dispersed over your roof.
You should replace your roof within three to five years if the cracks on your shingles are widespread. Another step you can take is to go up into your attic to check for cracks. Turn off the lights and look up at the roof to see if you can notice cracks. If light is coming in, there may be holes and cracks in the roof. If that is the case, you should fix it as soon as you can. Check to see if a repair can be made to your roof or if a replacement is required.

#4 Roof Rot

You have a serious structural issue when your roof is rotting. Wood rot is a result of prolonged exposure to moisture. This allows fungus to grow on it, which then causes the structure to deteriorate. It’s crucial to be able to recognize a deteriorating roof promptly so that the damage can be reduced.
Missing shingles or torn flashing are signs of roof rot. Look at your roof closely through a pair of binoculars from the ground to check for any shingles that are missing or torn flashing. If so, the roof deck underneath is exposed to the weather and may begin to deteriorate. If this is the case, you need to call a professional to fix it immediately.
Water damage on the ceiling is another sign of roof rot. If you notice water stains on your ceiling, there may have been a roof leak. Other signs of roof rot may also include mold growth in your attic, excessive growth of moss or algae or a sunken roof deck. These signs could point to the need for roof repair or replacement.

#5 Poor Energy Efficiency

Your heating bills may be gradually rising each year because your roof is poorly insulated. In many cases, homeowners that find their heating bills increasing only focus on insulating their windows and doors. Homeowners often neglect the roof not knowing that it could be the cause. If the roof is poorly insulated, hot air will escape from your house and cold air will enter. Due to this, energy costs may increase especially during the cold months.


If your roof exhibits any of these issues, it is wise to have a roofing expert take a look to determine the best course of action. Your roof could need to be replaced or restored depending on its condition. Ensure that you take the appropriate steps to avoid further damage to your roof and your house.
