Most roof replacements go to plan. The ones that do not go wrong in a small number of predictable ways: the deck turns out to be soft and nobody agreed a price for replacing it, the old flashing gets reused because it was not in the quote, a layover is done on a roof that already had two layers and should have come off, or the crew leaves and the nails stay in the driveway. Every one of those is avoidable at the quoting stage, and this article is how.
Finding a trustworthy roof replacement contractor is as crucial as understanding the individual components of the project. A reliable contractor can make a world of difference, ensuring every other decision falls into place effectively.
The most useful thing you can do before signing is agree in writing what happens when the surprises appear – because on an older roof they usually do. Agree the deck-replacement rate per sheet before the tear-off starts, agree that the flashing is new rather than reused, and agree who pays for a dumpster permit if the town needs one.

Should I Be Home During a Roof Replacement?
It’s generally recommended to be away from home during a roof replacement for safety and convenience. The process can be noisy and messy, involving loud machinery, falling debris, and potential hazards. Here are some reasons why it might be better to leave home during the project:
- Safety: Workers will be walking on the roof, using power tools, and handling heavy materials, posing a risk of accidents and injuries.
- Noise: The use of tools like nail guns, saws, and other equipment can be extremely loud, making it uncomfortable to stay indoors.
- Dust and Debris: The process can generate a lot of dust and debris, which can enter your home through vents, windows, and doors, creating a mess and potential respiratory issues.
- Inconvenience: Roof replacement can disrupt your daily routine, making it difficult to move freely around your home and use certain areas like the attic or upper floors.
If you decide to stay home, communicate with your roofing contractor about your presence and any concerns. They can take steps to ensure your safety and minimize disruptions. However, it is often more comfortable and safer to plan to be away during the roof replacement process.
15 Most Common Known Issues During the Roof Replacement Process
Planning a roof replacement involves being prepared for potential problems or setbacks. These issues can range from logistical challenges to quality concerns. As you navigate the planning process, keep these potential mistakes in mind, even those made by the most experienced roofers.
Failing to Use Starter Strips
Starter strips are essential in any roof replacement. They provide an adhesive layer that ensures the shingles are securely attached to the frame. Without starter strips, shingles are more likely to blow off in strong winds, compromising the roof’s integrity early in its lifespan.
Skipping the Ice and Water Shield
Sealing roof eaves with ice and water shield is a standard practice to prevent leaks and water damage. However, some “old-school” contractors might opt for traditional underlayment instead. Ensure your contractor uses ice and water shields, especially in wet climates, to protect vulnerable areas.
Relying on Low-Quality Pipe Collars
Roof vents are crucial for ventilation, but they can be common sources of leaks. Many contractors use low-quality collars around these pipes, which can wear out quickly. Ensure your contractor uses durable, high-quality collars cut to the right size to prevent leaks and water damage.
Trusting Caulking for Water Resistance
While caulking is useful for sealing around windows, doors, and in bathrooms, it’s not reliable for roof water resistance. Caulking can shrink and crack over time, allowing water to seep in. A proper flashing system combined with waterproof underlayment is a better solution.
Adding Layers in the Wrong Order
A successful roof replacement involves more than just shingles. The layers need to be applied in the correct order to ensure proper protection. Typically, the order starts with the eave, followed by the drip edge, ice/water guard, underlayment, flashing, shingles, and ventilation. Any deviation can compromise the roof’s effectiveness.
Overdoing the Flashing
Step flashing is used to improve water resistance, but overdoing it can create problems. Some contractors might overcomplicate the installation, leading to gaps and leaks. Flashing should be installed correctly to create a watertight seal without overcomplicating the process.
Using the Wrong Fastener Length
The nails used to fasten shingles to the roof deck must be the correct length. Using short fasteners can result in loose shingles that blow off or allow water to seep in. Ensure your contractor uses the appropriate fasteners for a secure and durable roof.
Neglecting the Roof Deck
The roof deck is the foundation of your roof. If it is weak or damaged, the quality of the installation won’t matter. Contractors should thoroughly inspect and replace any deficient decking to ensure a solid foundation for the new roof.
Damage to Landscaping and Property
Roof replacement can involve heavy machinery and foot traffic, which can damage your landscaping and property. Precautionary measures, such as using coverings and specific pathways, can minimize potential damage to plants, shrubs, fencing, and other belongings.
Color Mishaps
Choosing the color and style of your new roof is exciting, but it can be disappointing if the final result doesn’t match your vision. Work with a roofing company that offers sample boards and a color visualizer to see how the shingles will look on your roof. This helps ensure the final product meets your expectations.
Progress Interruption Due to Bad Weather
Bad weather, such as heavy rain, strong winds, or extreme temperatures, can delay your roof replacement. Adequate planning and flexibility in scheduling can help mitigate the impact of bad weather on the project timeline. Safety should always be a priority, and work should be postponed if conditions are unsafe.
Blocking of Parking Space
Roof replacement often requires large machinery and equipment, which can occupy parking areas. This can inconvenience residents, visitors, or delivery personnel. Clear communication about parking arrangements and temporary alternatives can minimize disruptions.
Leaky Oil Spots
Equipment used during roof replacement can leak oil or other fluids, which can damage the roof surface. Proper cleanup and maintenance techniques should be implemented to prevent oil spots from compromising the quality and durability of your roof.
Tripped Breakers
The use of power tools and equipment can strain your home’s electrical system, potentially tripping breakers or causing outages. Working with qualified electricians to assess and resolve any electrical issues can prevent disruptions and ensure safety.
Incorrect Installations and Home Warranty Void
Incorrect installations or deviations from standard practices can void existing home warranties or insurance. Improper techniques, such as inadequate flashing, incorrect fastening, or poor ventilation, can compromise the roof’s performance and lifespan. Ensure your roof is installed by licensed professionals who adhere to industry standards and manufacturer guidelines.
Finding a Roof Replacement Contractor You Trust
Unfortunately, many homeowners discover mistakes made by their contractors only after the fact. It’s rare for a contractor to admit past errors upfront. That’s why it’s crucial to be vigilant during the research phase. Be selective and ask plenty of questions before choosing a contractor. The best contractors will take the time to understand your project, inspect your roof thoroughly, and work with you to meet your specific needs.
By taking these steps, you can avoid common mistakes and ensure a successful roof replacement that enhances your home’s value and longevity.
