Warning Signs To Look Out For When Your Roof Needs To Be Replaced

We don’t need to remind you how important your home’s roof is because every responsible homeowner knows this well. Exposure to the weathering effects of the sun, cold, wind, water, ultraviolet rays, and more will gradually deteriorate your roof, no matter its material. This is why we must do whatever it takes to maintain and replace our roofs when the time inevitably comes. Despite this knowledge, many of us need help determining when this maintenance or replacement should occur. Here are some signs indicating that your roof needs to be replaced to help you navigate this potentially challenging aspect of property care and management.

Light Penetrating Through Holes in Your Roof

This is an undeniable sign that things are wrong. When light can get in where it shouldn’t, you can be sure that water and other unwanted substances are also finding their way in. Some of the biggest causes are rusted or corroded shingle nails, flashing, step flashing, or collars. To prevent the spread of these holes, have a professional roofer assess the damage as soon as possible.

Differences in Temperatures Between Your Attic and Outdoors

This might not be a well-known fact, but the temperature in your attic should match the outside temperature if your roof provides adequate ventilation. The temperature will automatically equalize when the air moves freely between your attic and the outside world. Ridge vents are parts of a roof responsible for this, so blocked ridge vents might result from deteriorating roofs, calling for roof replacement. 

The Buildup of Granules in Your Gutters

To make a quick check on the health of your roof, especially where most shingles are concerned, you can take a look at your gutters. If you notice granules accumulating in your gutters or downspout splash pan, it might be an indication that the granules covering your shingles are being weathered away and diminishing the effectiveness of your roof.

Constant Ice Dam Formation

Ice dams refer to ice formations on the edge of your roof or in your gutters, thus preventing water from flowing off your roof efficiently. This pooled water might then lift your shingles and seep into your roof, causing potential damage to your attic, insulation, and the roof itself.

Ice dams are typical signs of faulty roofing, so consider possible roof replacement if you notice this problem.

Visible Tar Streaks or Algae Growth

To keep their production costs low, various shingle manufacturers use limestone and materials such as this as a filler in their products. The problem is that bacteria are attracted to these materials as a food source, eating away the limestone content and allowing algae to grow and thrive on the roof. 

This development is also commonly behind the appearance of unsightly black tar streaks, which diminishes the waterproofing capacity of your roof.

Mold or Mildew Buildup

Two of the most common causes of inadequate ventilation in homes are over-insulation and blocked vents. These can occur in older as well as newer roofs. Under-ventilation may cause warm and moist air to become trapped in your attic and go on to encourage the development of rust and corrosion on the nails underpinning your roof.

Another significant danger that potentially comes with under-ventilation is mold or mildew development. These may not only be a danger to your roof but might cause respiratory conditions or ailments in the people living in your home. 

This is a particularly risky situation for homes containing particularly vulnerable people, who include the elderly, young children, and people with pre-existing respiratory conditions such as asthma.  

Curled or Buckled Shingles

When the shingles in your roof begin curling up or buckling, they are at great risk of being blown off or falling off entirely. This might come about due to moisture buildup underneath your roof, causing the nails holding your shingles to rust, weaken & and fall off.

Some of the signs of this occurring might include poor temperature regulation, water seepage, and the eventual deterioration of your roof.

Who to Call When Your Roof Needs to be Replaced

Most roofs should be replaced after 20 years of service, although this will vary depending on the type of roof and the conditions it has endured. Even so, you might need to do this much sooner than this because of poor installation, substandard materials, physical damage, or any other unforeseen circumstance.
