You do not have to remove lead paint if the surface is not chipping or peeling or if there are no pregnant people or children under the age of six who live in or regularly visit your home. Lead paint is a particular risk for young children whose brains and bodies are not fully developed. Experts strongly recommend that you call a pro to remove lead paint if it’s peeling or flaking, no matter who lives in the home. You can experience lead poisoning by breathing in or ingesting just a small amount of it.

Lead toxicity comes from inhaling lead or consuming it. Before the 1980s, when the government banned lead from consumer use, it could be found in paint, plumbing, pipes, ceramics, and even gasoline. Lead paint is toxic for the same reason lead itself is toxic, which is why lead poisoning from paint presents the same as lead poisoning from water or food sources, with a slight increase in respiratory symptoms vs. digestive symptoms. Lead paint is most dangerous when it’s old and peeling, cracking, or otherwise disturbed. This increases the concentration in the air and, therefore, in breathable air. 

If your roof was constructed between 1930 and 1970, there’s a possibility that the shingles contain asbestos. If that’s the case, you should hire a professional for repairs and replacement, as they’ll have the necessary equipment to stay safe from such a hazardous and cancer-causing substance. If your home was constructed after this period, it’s unlikely that the shingles in place are toxic. In most cases, asbestos shingles are not recyclable, while standard asphalt shingles are recyclable.

It is safe to remove old linoleum, but it may require the help of a specialist due to the risk of asbestos in the material. Before you cut into linoleum or try to peel it up, have it tested for asbestos. If it tests positive, professionals will need to remove it to prevent the risk of health issues from airborne toxic particles. If it’s asbestos-free, DIY removal is possible and safe.
