Renovation Risks: What Changes During Construction?

Home renovation projects are often planned around a vision for the finished space. But from a risk management perspective, every phase of construction can introduce new exposures. A home that is fully occupied and protected one day may be partially demolished, exposed to the elements, or otherwise operating under very different conditions the next. “Construction changes the risk profile of a property,” says Berkley One Personal Lines Risk Management Consultant Lisa Barnes.

“As conditions change throughout the project, it’s helpful for homeowners to understand what new exposures may emerge and what steps can be taken to help minimize them.”

From the earliest stages of demolition through final completion, construction can create a series of evolving risks that homeowners can consider.

Demolition

During demolition, portions of the structure designed to protect the home may be removed, exposing building systems and components that typically remain concealed. “Demolition introduces a level of uncertainty because systems that were previously protected become exposed,” says Barnes. “As work begins and areas of the home are opened up, the property can present very different hazards than it would under normal conditions.”

The demolition phase may also introduce additional property and safety exposures as contractors, equipment, and building materials move through the site. Urging contractors to maintain an organized work environment and follow established safety protocols can help reduce the likelihood of preventable incidents.

Open Framing and Structural Work

Once portions of a home’s exterior envelope have been removed, the property becomes more vulnerable to weather-related damage. Even routine seasonal conditions can have a greater impact when structural protections are temporarily absent. Construction delays can further extend this period of vulnerability, increasing the amount of time the home remains exposed. “When a structure is open to the elements, even a relatively minor weather event can have a substantial impact,” Barnes explains.

“Temporary protections and regular site monitoring become especially important during this stage.”

As construction progresses, site security may also require additional attention. Building materials, tools, and equipment can make a property more attractive to thieves, particularly when workers are not present. Protective measures designed to control access to the site and discourage unauthorized entry can help reduce these exposures.

Roof Replacement Projects

Few construction phases alter a home’s risk profile as dramatically as roof work. When a roof is removed, even temporarily, one of the property’s most important protective barriers is compromised. This increases the potential for weather-related damage. “The period when a roof is being replaced requires close attention to weather conditions, scheduling, and contingency planning,” says Barnes. “Having appropriate temporary protections and a clear response plan can make a meaningful difference if conditions change unexpectedly.”

Because conditions can shift quickly during a roofing project, coordination among everyone involved becomes especially important. Ongoing oversight, temporary protective measures, and preparedness for changing weather can help reduce the likelihood of a significant loss while work is underway.

Vacancy and Limited Occupancy

Many renovation projects involve second homes or properties where homeowners are not present daily. In these situations, problems that would otherwise be detected quickly may remain unnoticed. “If someone is living in the home, they’re much more likely to spot a problem early, whether it’s water, smoke, or evidence of unauthorized access,” says Barnes. “When the property isn’t occupied, monitoring and oversight become even more important.”

Depending on the project, contractors and property owners may consider measures such as alarm systems, water detection devices, remote monitoring technology, or scheduled site visits to help identify issues before they become larger losses.

When the Home Is Fully Enclosed

While risks may appear minimized once the structure is enclosed, significant exposures can remain. In the final stages of construction, valuable materials begin arriving onsite and installation work intensifies throughout the home. As activity increases, so does the potential for accidental damage and other losses.

“As construction nears completion, people sometimes assume the greatest risks have passed,” Barnes says. “In reality, this is often when valuable materials are entering the property and loss prevention remains critically important.”

Even as a renovation begins to resemble a finished home, maintaining strong oversight and risk-management practices remains important.

A Practical Approach Throughout the Project

No two renovation projects are identical, but one principle remains consistent: risk management should evolve alongside construction. As conditions change throughout a project, new exposures may emerge while others recede, making ongoing evaluation an important part of the process.

Effective loss prevention often depends on recognizing those shifts early and adapting to them. Whether a home is undergoing demolition, waiting on materials, or approaching completion, attention to changing conditions can help reduce the likelihood and severity of a loss.

“Successful projects aren’t defined only by the finished result,” says Barnes. “They’re also the projects where attention is given to managing risk every step of the way.”
