What is Roof Flashing & Do You Need Yours Replaced?

April 3, 2023

Have you ever wondered why some roofs last for decades, while others are constantly needing roof repairs? The answer lies in one of the most overlooked aspects of roof installation: roof flashing. When applied correctly and regularly maintained, roof flashing can be the difference between a roof leak nightmare and a long-lasting haven. Let’s explore the details behind this important piece of your home.

What is Roof Flashing?

Roof flashing is a thin sheet material that is placed around edges and joints on your roof to help direct water away from these areas. It typically comes in metal or rubberized asphalt, but other materials such as plastic, lead, and copper can also be used depending on the situation. Many times it’s used around plumbing vents and chimneys, but it can also be used along dormers, valleys, eaves, ridges, and hips. Not only does it provide waterproofing protection for your home, but it also helps prevent ice dams from forming in cold climates.

Reasons Why You May Need to Replace Roof Flashing

Over time, the roof flashing can develop problems that require special attention from professional roofing and building contractors. The following are some common signs that you may need to replace your client’s roof flashing:

Cracked or Bent Flashing

A roofing contractor may recommend replacing the roof flashing if the roof metal flashing is cracked or bent. To ensure the flashing is providing the intended protection against water intrusion, it needs to be in good condition with no visible signs of damage. Once the flashing has been compromised, replacing it as soon as possible is crucial to prevent further damage.

Corroded or Rusted Areas of the Flashing

Another red flag that roof flashing may need to be replaced is if you spot any corroded or rusted areas. If there are significant areas of corrosion or rust, then this indicates that water has been able to get through and cause damage. It’s best to inspect and assess the condition of the roof flashing so you can determine whether replacement is necessary.

Damaged Sealants

Sealants are used for many purposes when installing roof flashing, including creating waterproof barriers between surfaces such as metal and wood. Suppose these sealants become damaged over time due to exposure to weather elements. In that case, they need to be replaced for the structure of a roof system to remain intact and free from leaks and other potential issues.

Water Pooling Around Chimneys, Vents, and Other Structures on the Roof

If you notice water pooling around chimneys, vents, and other structures on the roof, this could indicate a problem with your existing flashings – mainly if these structures are not correctly sealed off from the rest of the roof system. In this case, replacing broken or worn-out flashings will go a long way toward preventing water from getting into areas where it should not be.

Missing Sections of Flashings

Lastly, missing sections of flashings will require immediate replacement for water tightness on certain parts of your home’s roof system to remain intact. While small holes can probably be patched up with additional sealant applications, larger gaps will need entirely new sections of flashings installed for these areas to remain protected from moisture intrusion.

Identifying Warning Signs That Replacement Is Necessary

In addition to assessing the condition of existing flashings, some warning signs indicate when it’s time to replace them entirely. These include discoloration on walls near where building contractors install these pieces due to trapped moisture beneath them, leaking around walls near windows due to cracks in the sealant, and an increase in exterior noise due to air entering through gaps caused by missing material between flashings.

It is also essential to look out for bubbling paint on ceilings which can be an indication that moisture has made its way up into your home through faulty roof flashing materials; shingle granules coming off your roof, which could mean they have become too old and worn down, and finally, any visible damage caused by impact from hail or falling tree branches which could warrant an immediate replacement regardless of age or condition.

Considering all these factors should give you a better idea about whether or not new roof flashing should be installed.

What to Look for When Making Replacements

Replacing roof flashing can be a tricky job. As experienced residential roofing and building contractors, we understand how important it is to ensure that the materials chosen for your replacement are up to the task and suited to your needs.

Roof Flashing Types

When choosing a replacement material for your roof flashing, a few options are available. Common materials used for roof flashing include a metal flashing such as aluminum, galvanized steel, or zinc; rubber or plastic; and asphalt-saturated felt (sometimes referred to as tar paper). Each of these materials has its advantages and disadvantages, which you should consider before making your decision. For example, metal roof flashing is often more durable than other materials but can be more expensive, while asphalt-saturated felt may not last as long but may cost less upfront.

Potential Durability Issues with Roof Flashing

Another factor to consider when replacing your roof flashing is potential durability issues with your chosen material. Suppose the material isn’t strong enough to withstand harsh weather conditions or is not installed correctly by experienced professionals. In that case, there’s a good chance that you’ll eventually have to replace it again due to wear and tear caused by elements like rain and wind. This means that whatever material you choose should be able to hold up against extreme temperatures and heavy rains without losing its shape or cracking over time.


The next factor you should consider when selecting a replacement material for your roof flashing is cost. While metal can provide outstanding durability and weather resistance, it may not always be within your budget. Asphalt-based products tend to be cheaper but lack many benefits associated with metal, such as strength and flexibility in changing climates. Therefore, it’s essential to compare different materials and price points to make an informed decision based on quality and cost-effectiveness.

Installation Difficulty

The last factor you should consider when choosing a replacement material for your roof flashing is installation difficulty. Metal roof flashing is typically more challenging to install than other materials. Asphalt products can be easier to install but may not always provide the same level of protection as metal due to their lower durability ratings. Therefore, it’s essential to consider the difficulty of installation when selecting a replacement material to ensure the job is done correctly and safely.

Making a Case for Professional Roofing Contractors

As any homeowner knows, roof flashing is a vital component of the roofing system, protecting from water leaks and other damage. But when it’s time to replace their roof flashing, they may want to replace it independently. This creates the perfect opportunity to recommend the benefits of hiring professional roofing contractors for flashing replacements.

When it comes to replacing roof flashing, there are several key advantages to hiring professional contractors. For starters, roofing contractors have an in-depth knowledge of material selection and installation methods that will ensure new flashing is correctly installed to provide long-term performance and protection against further damage.

Furthermore, experienced contractors can also offer valuable insight into safety precautions depending on the type of rooftop your client has. Whether it’s a steeply sloped metal roof or a flat tile one – professional advice can go a long way in helping ensure that repair work goes as smoothly as possible.

Finally, many reputable companies offer guarantees for their workmanship so clients can rest assured knowing that if something goes wrong with their flashing installation down the line, they’ll be able to help get it sorted quickly and efficiently.

Explaining these benefits to clients can help them decide about their roof flashing replacement and ensure their rooftop is protected for many years. When owners consider all the advantages professional building contractors offer – such as specialized expertise in dealing with various types of roofs; quality guarantees for long-term performance; and safety precautions – it becomes clear that these extra services are worth every penny if they want peace of mind while keeping their family safe.
