12 Common Threats to Your Roof’s Structural Integrity

When it comes to keeping your home safe and secure, the roof can often be overlooked or underestimated. The roof of your home is a fundamental part of your property’s overall structural integrity, and plays an integral role in protecting the interior of your home from the elements.

A weak or damaged roof can create long-term problems such as water damage, rotting wood, or even an unstable foundation. In order to ensure your home’s longevity and safety, it is important to keep your roof in good condition and take a proactive approach to preventing damage.

This article will cover the most common causes of roof structure damage, best practices for prevention, warning signs of a weakened roof structure, steps to take when roof damage is detected, and preventative measures that homeowners can take to extend the life of their roof.

What are the most common factors that threaten a roof’s structural integrity?

Water Damage

One of the most common causes of roof deterioration is water damage. Rain, sleet, and snow can all erode away at the protective layers of your roof. To prevent such issues, you need to regularly maintain your roof. Check out our article on the best 12 ways to proactively protect your roof’ for practical tips.

Constant exposure to cold and wet weather also accelerates the breakdown of shingles, tiles, and other materials. Make sure to check for bad drainage systems, unsealed seams around vents, and drips near the eaves. Ensuring that your gutters are regularly cleaning and checking to make sure there are no clogs is key to avoiding water damage.

Sunlight / UV Rays

The sun can act as a silent enemy to the roof of your home. Prolonged exposure to direct sunlight can cause the roofing materials to become brittle and dry out over time. Sunlight also contributes to the growth of moss and algae, which can trap moisture in your roof and speed up the deterioration process. Installing a reflective coating can help reduce sun damage and keep your roof cool.


Having trees around your home can be great for aesthetic purposes, but they can also cause considerable damage to the roof. Roofs can be damaged by tree branches that rub against them and cause abrasions, fallen leaves and debris that block drains and restricts water runoff, potentially leading to leaks which are often hard to spot. Read our article on ‘Why it’s difficult to locate a roof leak on your own’ to learn more about this issue. Make sure to trim back any vegetation near your roof and clear away debris on a regular basis.


Hail storms can easily cause structural damage to your roof. Also, wind combined with hail can be particularly damaging. It’s important to understand that there are 3 Common Misconceptions About Wind Damage on Roofs. By reading this article, you’ll gain a better understanding of how these elements can impact your roof.

While larger hailstones can create dents and cracks in the roofing material, smaller pebbles can accumulate and lead to deterioration over time. Regularly inspecting your roof for storm damage should be a priority after every major storm.


High winds can easily strip away roofing materials and cause roofing membrane to become loose. Tornadoes and hurricanes are capable of tearing off entire pieces of the roof and leave your home exposed to the elements. It’s important to consider wind speed restrictions in your area when selecting a roofing system.

Ice Dams

Ice dams are caused when melted snow refreezes at the eaves of your roof, forming chunks of ice. These can trap moisture and encourage granules to wash away from asphalt shingles, leading to costly repairs. Using proper ventilation and insulation techniques can help prevent ice dams from forming in the first place.


Ponding is when water collects and stagnates at specific areas on the roof. If left untreated, this moisture can lead to serious damage. Inspect your roof regularly to make sure that water is draining properly and there are no areas where ponding may occur.


Pests and animals can cause considerable damage to your roof, creating holes and allowing access to the attic of your home. Small holes created by rodents can lead to water damage and provide the perfect breeding ground for mold.

Clogged Gutters

Gutters play an essential role in providing protection to your roof. Clogged gutters can easily lead to water buildup around the edge of the roof and cause serious damage. Regularly clean your gutters and ensure that they are functioning properly.


Time is an unavoidable factor when it comes to roof health. Even the highest quality roofing materials break down over time due to normal wear and tear, and must eventually be replaced. Depending on the roofing material you choose, having regular inspections and making small repairs when needed can go a long way in ensuring the longevity of your roof.

Poor Installation

In some cases, poor installation is the root cause of structural damage. When choosing a roofing material like asphalt shingle, it’s crucial to ensure the quality of installation. Find out the 4 Qualities to look for in good asphalt shingle roofing in our helpful guide.
