Is Roofing Lead Dangerous? (The Complete Guide to Roof Lead Exposure)

Roofing lead exposure is a serious issue, but it can be managed if you’re careful. Here’s what you need to know!

Is roofing lead dangerous?

Yes, roofing lead can be dangerous if proper safety precautions are not taken during installation, removal, or repair. Lead is a toxic metal that can cause serious health problems if it enters the body, particularly through inhalation or ingestion. When lead is moved, like when roofing materials are taken off or cut, it can make fine particles or dust that can be inhaled or swallowed.

Some of the health effects associated with lead exposure include:

Damage to the central nervous system
Impaired cognitive function and learning difficulties
Behavioral problems

Kidney damage
Reproductive problems
Developmental delays in children

Why is lead used on roofs?

Lead has been used on roofs for centuries because of its durability, malleability, and resistance to corrosion.

It is a very flexible and easy-to-work-with metal that can be bent and shaped to fit complex roof structures. This makes it a popular choice for roofing in historic buildings and traditional architecture.

Lead is also very resistant to water and can withstand very high and very low temperatures. This makes it a good material for roofing in places with rough weather.

Its low melting point also makes it easy to work with, allowing for intricate detailing and decoration on roofs.

Also, lead is a relatively heavy material, which can help provide stability and support for the structure of a building.

It is also a very environmentally friendly material because it is easy to recycle and can be used for other building projects.

But it’s important to note that the use of lead in construction and roofing has decreased in recent years because of growing concerns about the health and environmental risks of lead exposure.

Many countries have laws that limit how much lead can be used in building materials. Instead, aluminum, zinc, and copper are now more often used as roofing materials.

What are the dangers of lead exposure?

Lead exposure can cause a wide range of health problems, particularly when exposure is long-term or at high levels. Some of the key dangers of lead exposure include:

Brain damage: Lead exposure can cause permanent damage to the brain and nervous system, particularly in children. This can result in a range of problems, including impaired cognitive function, reduced IQ, learning difficulties, and behavioral problems.
Affects a person’s ability to think and concentrate: Lead exposure can also affect a person’s ability to think clearly, concentrate, and make decisions. This can have a significant impact on daily life and work performance.
Developmental delays in children: Children who are exposed to lead can experience delays in physical and mental development. This can result in issues such as delayed speech and language development, difficulty with fine motor skills, and behavioral problems.

Reproductive problems in men: Lead exposure has been linked to reduced fertility and other reproductive problems in men, including a decreased sperm count and abnormal sperm shape.
High blood pressure and kidney damage: Exposure to lead can also cause damage to the kidneys and increase the risk of high blood pressure. This can have serious long-term health consequences.
Mood disorders and psychosis: Lead exposure has been linked to mood disorders, including depression and anxiety, as well as more severe psychiatric problems such as psychosis.

Damage to the nervous system: Lead exposure can cause damage to the nervous system, resulting in problems such as numbness, tingling, and muscle weakness.
Seizures and even death: In extreme cases, lead exposure can cause seizures and even death, particularly in cases of acute poisoning.

Can lead roofs harm the family?

If the roof isn’t put on, maintained, or taken off correctly, the lead could hurt the family. Lead is a toxic metal that can cause serious health problems if it enters the body, particularly through inhalation or ingestion.

If lead roofing is broken, cut, or taken off without taking the right steps, it can release small pieces or dust that can be inhaled or swallowed.

This can result in lead exposure, which can cause a wide range of health problems, particularly in children, pregnant women, and individuals with weakened immune systems.

To reduce the risk of lead exposure from roofing, it’s important to make sure that any work that involves lead roofing is done by trained professionals who follow safety rules.

This can mean wearing protective clothing, gloves, and a respirator to keep from breathing in lead dust and properly getting rid of anything with lead in it to keep the environment from getting contaminated.

If you suspect that your family may have been exposed to lead from roofing or other sources, it’s important to seek medical attention right away.

A blood test can tell if someone has been exposed to lead, and getting help early can help reduce the risk of long-term health problems.

What does lead do to the body?

Lead is a toxic metal that can cause a wide range of health problems when it enters the body. Lead can get into your body through your lungs, stomach, or skin. The effects of lead depend on how much and how long you are exposed to it.

Some of the ways that lead can affect the body include:

Brain and nervous system

Lead exposure can cause damage to the brain and nervous system, particularly in children. This can lead to a wide range of problems, such as poor cognitive function, a lower IQ, trouble learning, and bad behavior.

Reproductive system

Lead exposure has been linked to a man’s inability to have children and other reproductive problems, such as a lower sperm count and an odd shape for his sperm.

Cardiovascular system

Exposure to lead can increase the risk of high blood pressure and damage to the kidneys, which can have serious long-term health consequences.

Gastrointestinal system

Lead exposure can cause abdominal pain, nausea, vomiting, and other gastrointestinal problems.

Hematological system

Lead can stop the body from making enough red blood cells, which can cause anemia and other blood disorders.

Musculoskeletal system

Exposure to lead can cause muscle weakness, joint pain, and other musculoskeletal problems.

Behavior and mood

Exposure to lead has been linked to mood disorders like depression and anxiety, as well as more serious mental health problems like psychosis.

Developmental delays

Children who are exposed to lead can experience delays in physical and mental development. This can lead to problems like speech and language delays, trouble with fine motor skills, and behavior issues.

In extreme cases, acute lead poisoning can cause seizures and even death. Lead is a cumulative poison that can be inhaled, ingested, or absorbed through the skin and can have serious long-term health effects.

What are the sources of lead exposure on roofs?

Lead-based paint

Lead was commonly used in paint until it was banned for use in residential buildings in 1978. However, many older buildings may still have lead-based paint, which can flake or chip over time and contaminate the surrounding area.

Lead shingles

Lead has also been used as a roofing material, particularly in historic buildings. Over time, lead shingles can deteriorate and release lead particles into the air.

Chemicals

Lead can be found in things like solder, sealants, and flashing, which are all used in roofing. During installation, maintenance, or repair work, these chemicals can let lead dust into the air.

Gutters

Lead can be present in the material used to make gutters, particularly in older homes. When gutters are damaged or deteriorated, lead particles can contaminate the surrounding area.

Metal roofs

While lead is not commonly used as a roofing material today, it can be present in metal roofing products that were manufactured prior to the 1970s.

Metal roofing nails

Nails used to secure roofing materials can contain lead, particularly in older buildings. When these nails rust or degrade, lead particles can be released into the air.

Roof water collection systems

Lead can also contaminate the water collected from roofs, particularly if the roofing materials contain lead or if lead-based materials are used in the gutter system.

Building materials

Lead can be found in flashing, sealants, and mortar, all of which are used in roofing. During installation, maintenance, or repair, these materials can give off lead particles into the air.

Smoke from burning lead

Lead can be released into the air when lead-based materials are burned, such as during demolition or renovation work. This can result in widespread contamination and exposure.

How can you protect yourself and your family from lead exposure from roofing?

If you are concerned about lead exposure from roofing materials, there are several steps you can take to protect yourself and your family:

Identify potential sources of lead: If you live in an older home or work in a building with a historic roof, it’s important to identify potential sources of lead exposure. This may include lead-based paint, lead shingles, metal roofing products manufactured prior to the 1970s, and other building materials that contain lead.
Hire a professional: If you need to perform any maintenance or repairs on your roof, it’s important to hire a professional who is trained and experienced in working with lead-containing materials. They can take steps to minimize exposure, such as using protective equipment and following safe work practices.
Use personal protective equipment: If you are working with roofing materials that contain lead, it’s important to wear personal protective equipment, such as gloves, goggles, and a respirator.

Avoid creating dust: When working with lead-containing materials, it’s important to avoid creating dust or debris that can be inhaled or ingested. This may involve wetting down surfaces, using a vacuum with a HEPA filter, or using other dust suppression techniques.
Keep children and pets away: If you are working with lead-containing materials, it’s important to keep children and pets away from the area to prevent accidental exposure.
Practice good hygiene: After working with lead-containing materials, it’s important to practice good hygiene, such as washing your hands and face thoroughly and changing your clothes before coming into contact with others.

Test your water: If you collect water from your roof, it’s important to test it for lead contamination. You can also install a filter that is certified to remove lead from water.

What do roofers use instead of lead?

Lead is bad for your health and the environment, so many roofers now use other materials for roofing and flashing instead of lead. Some common alternatives to lead include:

Zinc

Zinc is often used instead of lead for roofing and flashing because it has many of the same qualities as lead, such as being strong, malleable, and resistant to corrosion. Zinc is another mineral that is found in nature and is safe for people and the environment.

Copper

Copper is also a popular alternative to lead because it lasts a long time and doesn’t rust. Copper is also a natural material that is not harmful to humans or the environment.

PVC

Polyvinyl chloride, or PVC, is a man-made plastic that is often used to seal the edges of roofs. While PVC is not as durable as metal alternatives, it is lightweight, affordable, and easy to install.

EPDM

Ethylene propylene diene monomer (EPDM) is a synthetic rubber material that is commonly used as a roofing material. EPDM is highly durable and resistant to UV radiation and weathering.

Aluminum

Aluminum is a strong, lightweight metal that is often used for roofs and flashing. It is highly resistant to corrosion and weathering, making it a good alternative to lead.

Stainless steel

Stainless steel is a strong, long-lasting metal that doesn’t rust or get worn down by the weather. It is often used as a roofing material and for flashing, and it can be a good alternative to lead.

Titanium

Titanium is a strong metal that doesn’t weigh much and doesn’t rust or wear down easily. It is often used as a roofing material, and it can be a good alternative to lead.

Asphalt

Asphalt is a popular roofing material that can also be used for flashing. It is affordable, easy to install, and highly resistant to weathering.

Rubber

Rubber is a flexible and durable material that is commonly used for flashing. It is resistant to weathering and corrosion, and it can be a good alternative to lead in certain applications.

Composite materials

For roofing and flashing, composite materials like fiberglass-reinforced plastic (FRP) and polymer-modified bitumen (PMB) are becoming more and more popular. These materials are lightweight, durable, and highly resistant to weathering and corrosion.

When are you most at risk for lead poisoning as a roofer?

The risk is highest when the lead is in a form that is easy to breathe in, eat, or absorb through the skin. Here are some situations where roofers may be at increased risk for lead poisoning:

Removing or installing lead flashing: When roofers remove or install lead flashing, they may generate lead dust or particles that can be inhaled or ingested. Roofers may also be exposed to lead dust or particles if they cut or manipulate lead flashing.
Cutting or welding lead: When roofers cut or weld lead roofing materials, they may generate lead dust or fumes that can be inhaled or absorbed through the skin. This can be particularly dangerous if the roofer is working in a confined or poorly ventilated space.

Handling lead-based paint: If roofers are working on an older building that contains lead-based paint, they may be exposed to lead dust or particles when they scrape or sand the paint. They may also be exposed to lead dust or particles when they handle or dispose of lead-based paint.
Eating or drinking on the job: If roofers eat or drink on the job without washing their hands or using proper hygiene practices, they may ingest lead particles that are present on their hands or in their food or drink.
Using lead-based solder: Roofers who use lead-based solder to join copper or other metal roofing materials may be at risk for lead exposure if they inhale the fumes or touch the solder with their bare hands.

Using lead-based sealants: If roofers use lead-based sealants or caulks on roofing or flashing materials, they may be exposed to lead dust or particles if they sand or cut the sealant.
Handling contaminated materials: Roofers who handle or remove contaminated roofing or flashing materials, such as those that have been exposed to lead dust or particles, may be at risk for lead exposure if they inhale or ingest the particles.
Working in confined spaces: If roofers are working in a confined space, such as an attic or crawl space, where there is little ventilation, they may be at increased risk for lead exposure due to the concentration of lead dust or fumes in the air.

Working with contaminated tools: If roofers use contaminated tools, such as saws or hammers that have been used to cut or manipulate lead materials, they may be at risk for lead exposure if they inhale or ingest the lead particles.

How do you test for lead poisoning?

Blood test: A simple blood test is the most common way to test for lead poisoning. The test measures the amount of lead in the blood. The Centers for Disease Control and Prevention (CDC) recommends that children between the ages of 1 and 2 be tested for lead exposure at least once a year, and more frequently if they are at higher risk for exposure. Children with blood lead levels at or above 5 mcg/dL should be periodically tested, and those with levels of 45 mcg/dL or higher should receive treatment. In adults, a blood lead level of 5 µg/dL or higher is considered elevated, and treatment may be recommended if the level exceeds 80 µg/dL or if the individual has symptoms of lead poisoning and the level is greater than 40 µg/dL.
X-ray: An X-ray may be used to detect the presence of lead particles in the body. This test is typically used if a person has swallowed a large amount of lead, as the particles will show up on the X-ray. Plain radiographs of the skeleton have been commonly employed for diagnosing lead poisoning in children. Such radiographs have been found to be dependable in cases of young infants who exhibit unexplained encephalopathy. The presence of dense metaphyseal bands in a knee radiograph can significantly aid in confirming the diagnosis of lead poisoning.

Urine test: A urine test may be used to detect recent exposure to lead. However, this test is not as accurate as a blood test, as it only measures the amount of lead that has been excreted in the urine, rather than the amount that is currently in the body. When an individual excretes over 125 mg of lead in their urine within 24 hours, it typically indicates the presence of other signs of lead poisoning.
Hair analysis: A hair analysis may be used to detect long-term exposure to lead. The test measures the amount of lead that has been stored in the hair over a period of several months. This means that with a hair sample, researchers can approximate when you were exposed.

Lead poison cases found in the US

Eight cases of lead poisoning in roofers encountered at the Los Angeles County General Hospital over the past six months. It is believed to be a new hazard for this occupational group, as no similar cases have been reported in the literature. All of the patients were male, with two exceptions, and ranged in age from early adulthood to ten years of experience as roofers. All of them reported holding galvanized roofing nails in their mouths while working, and none of them reported any other exposure to lead.

Data from the National Health and Nutrition Examination Survey (NHANES) was used to analyze the association between lead exposure and mortality. They found that around 412,000 of the deaths in the U.S.A. were from lead poisoning.
A study published in The Lancet Public Health found that individuals with a blood lead concentration at the 90th percentile (6.7 micrograms per deciliter) had a 37 percent increase in mortality, and a 70 percent increase in cardiovascular disease mortality compared to those with a blood lead concentration at the 10th percentile (1.0 microgram per deciliter). This suggests that lead exposure could be an overlooked contributing factor to this cause of death. The estimated number of deaths attributable to lead were comparable to the number of deaths from tobacco smoke exposure.
A study conducted by researchers at the Icahn School of Medicine at Mount Sinai in New York City, which found that lead exposure is a risk factor for cardiovascular disease. The study found that even low levels of lead exposure can increase the risk of cardiovascular disease, and that the number of people affected by this risk is much higher than previously thought. The study relied heavily on one blood concentration measurement taken at the beginning of the study period, which is a limitation of the study. The researchers believe that the results of the study will likely impact how physicians think about lead exposure as a risk factor for cardiovascular disease, particularly among older adults.
