5 Signs of a Failing or Faulty Roof

Last Updated on June 25, 2024 by SampleBoard

Do you notice damaged shingles, leaks, a sagging deck, an aging roof, or granule loss on your roof?

Your home's safety, energy efficiency, and aesthetic appeal all depend on the condition of your roof.

However, as time passes, this "first line of defense" may begin to fail and exhibit vulnerabilities that could result in more serious issues.

Early detection of the warning signs of a failing roof will help you prevent future leaks, structural damage, and expensive repairs. 

Here are five critical signs to be aware of.

Shingles That Are Missing, Cracked, or Curled

Your roof's outermost layer of protection, shingles, is made to resist weather conditions and repel water.

Shingles can deteriorate with time from exposure to sun, wind, and rain; symptoms may include cracking, curling at the margins, or total separation.

These physical alterations indicate a decline in the roof's ability to prevent water intrusion, which in turn compromises the house's appearance. 

Water entering through these gaps can leak into your home, seriously harming the underlying roofing materials.

These issues necessitate emergency roof repair services, as neglecting them not only poses a risk to your and your family's safety but also compromises the aesthetic appeal of your home.

It’s also worth mentioning that you should probably avoid DIY. Some roof repairs are best left to professionals; you can easily get injured if you try to do them yourself.

Aged Roof

Some factors that affect a roof's lifespan are the materials used, the precision of the installation, and the surrounding conditions.

Asphalt shingle roofs, ubiquitous in many homes, are usually expected to last between 20 and 30 years; however, metal and tile roofs can last longer. 

Routine maintenance can significantly extend the longevity of your roof. But of course, there will come a time when you simply have to install a new roof to ensure security and boost your house's comfort.

Water Damage and Leaks

Often, the most obvious and urgent indication that a roof is failing is a leak. They may show up as flaking paint beneath roof overhangs, wet patches next to fireplaces, or dark stains on ceilings.

Water damage can be subtle. It gradually weakens your home's structural integrity, encourages the growth of mold, and sometimes harms electrical systems.

These leaks could be caused by damaged flashing, deteriorated shingles, or clogged gutters rather than by obvious roof holes. 

It can be challenging to find the cause of a leak, therefore thorough inspections both inside and outside the home are required.

Leaks must be located and treated as soon as feasible to prevent minor issues from worsening and necessitating more costly repairs or even a new roof.

Sagging Roof Deck

A sinking roof deck is a warning sign of severe structural deterioration, frequently brought on by extended exposure to damp or insufficient support.

This problem is evident from the outside or inside of the house as a distinct dip or droop between the rafters or trusses.

It implies that the structural elements or roofing materials are decaying from water damage or collapsing beneath the structure's weight. 

Sagging presents a serious safety danger and compromises the roof's structural integrity and visual appeal.

It may result from structural support deterioration or overloaded roofing materials, such as heavy snow buildup.

It is imperative that a structural engineer or roofing professional evaluate the situation as soon as possible to evaluate the degree of the damage and identify the necessary repair activities.

Shingle Granule Loss

Ceramic granules are applied to asphalt shingles to provide protection against UV radiation and weather.

Certain granules naturally dislodge with time and wash into the gutters; this process quickens as the shingles disintegrate.

If you notice an abundance of these granules in your downspout splash blocks or gutters, it may indicate that your roof is nearing the end of its life.

Granule loss exposes the shingles' asphalt covering to the weather, thus lowering its protective power and increasing the risk of water damage to your roof.

Homeowners may be able to detect this problem early on with routine gutter cleaning and inspection, which may indicate that roof replacement or repairs are necessary to maintain the home's protection.


You shouldn't ignore the condition of your roof. It's essential to preserving your house's energy efficiency, weatherproofing, and visual appeal.

A sinking roof deck, missing or damaged shingles, water damage, an aging roof, and the loss of shingle granules are the five telltale symptoms that your roof may need to be replaced.

Acting on these signs promptly can significantly mitigate the risk of more severe damage and potentially exorbitant repair costs.

Matter of fact, a proactive maintenance program is shown to lower the average life-cycle cost of a roof to $0.14 per square foot, significantly less than the cost incurred from reactive maintenance practices.
