Health Hazards: Mold and Mildew Growth

The growth of mold and mildew is one of the most significant hazards that can result from ignorance of roof leakage.

They can start developing in moist environments in as little as 24–48 hours after the water damage occurs. 

And can also lead to respiratory illness, allergies, and even severe neurological problems that might trigger a chronic disease and, in dire situations, may lead to death. 

These fungi can have severe effects on patients suffering from prior lung conditions such as asthma. 

Higher Utility Bills

Ignoring the water leakage will greatly impact your home’s insulation, and it will be terribly difficult for you to keep the house cool in the summer and warm in the winter.

The overworked HVAC system can lead to hyperconsumption of energy, which results in high utility bills.

You must understand this thing that even something that seems like a small leak can tremendously impact your comfort and expenses.

Taking this concern into account, it is suggested to make frequent checks to maintain the level of concealed drips.

Impact on Property Value

If, in any case, even in the future, you think of selling your house, the leaking roof can seriously lower the value of your property, or you might not even find any dealer. 

The majority of clients will surely view this concern as alarming, and it is even easy to understand why.

This is not a hidden fact that water damage can lead to mold, rot, and other more serious problems.

Even the most minor of leaks can create unsightly stains on ceilings that will lower the value of the home in the eyes of potential buyers. 

Sustaining the roof in good shape not only protects the home but also the investment, so a homeowner should not lose value because of a simple leak.

Insurance Implications

A small roof leak may seem trivial to you, but it can cause severe problems not only to your home but with your insurance claims as well.

The majority of insurance companies only cover damages that are unexpected and accidental. 

That means if an insurer finds out that your negligence in maintaining the leakage is the reason behind the damage, they will deny paying your claim.

And as a result, at last, you will be the one who has to pay for the hefty amount of repairs by yourself. 

That being said, claiming repairs early helps avoid the loss of coverage and mitigates costs, and this contributes positively to your home and financial plans.

Maintaining your roof’s health is an ongoing effort, however, there are a host of techniques worth adopting. 

Here are some principles that should be put in place:

  •  It is advised to maintain the cleaning of the downspouts and gutters, so there is no buildup of water on the roof, which can lead to leaks. 
  • Another thing to be ensured of is that there are no moisture-retaining Poplar or Oak trees nearby.
  • As a precautionary measure, it’s highly recommended to cut tree branches that overhang your property.
  • To better withstand rough weather conditions, it is also suggested that a protective coating be applied to the roof.
