Replacing a roof is a major investment, and one of the most common questions homeowners ask is, “How long will it take?” The actual roof installation itself is usually completed in just a few days, but the entire process—from initial inspection to the final cleanup—can take anywhere from four to nine weeks, depending on various factors.
The timeline depends on permit approvals, material selection, roof complexity, weather conditions, and contractor availability. If your roof replacement involves an insurance claim, the process may take even longer while waiting for approvals.
At Hammersmith Roofing & Construction, we make the process as efficient as possible while still doing the job with excellence. Below, we’ll break down each stage of a roof replacement so you know exactly what to expect.
The first step in a roof replacement is a thorough roofing inspection to assess the current condition of your roof and determine if a complete replacement is necessary. A professional will check for leaks, structural damage, missing shingles, and compromised flashing, often using roof photography to document any problem areas. If hidden damage is discovered—such as roof deck deterioration or signs of water intrusion—this may extend your timeline as additional repairs could be required.
After the inspection, the contractor will provide a detailed estimate outlining labor, materials, and potential additional costs. If you’re filing an insurance claim, this is the stage where you’ll coordinate with your insurance carrier to get approvals, which can potentially add extra time. While the inspection itself only takes a few hours, scheduling and receiving the estimate typically takes one to three days.
Most local governments require a building permit for a roof replacement, ensuring the project meets local building codes and safety regulations. The approval process can take anywhere from a few days to weeks, depending on how quickly your municipality processes applications. You may need additional approvals if your roof replacement involves significant structural changes—like adding dormers or altering the roof slope.
Suppose you live in a neighborhood with a Homeowners Association (HOA). In that case, you may also need approval for material type, color selection, or even the style of your new roof, which can tack on additional time.
Fortunately, most roofing contractors will handle the permit application process on your behalf, but it’s still important to account for this in your timeline. In most cases, homeowners should expect the permitting process to take anywhere from one to three weeks. However, if your city has a backlog of applications or additional inspections are required, this phase can take up to three weeks before work can officially begin.
Your choice of roofing materials can have a major impact on the overall timeline. Standard options like asphalt shingles are usually in stock. They can typically be delivered within one to two weeks, while specialty materials like slate or metal may require custom orders that can take up to four weeks or longer. The amount of material needed to complete the job is also a factor—depending on your roof size, sourcing materials could take longer. Supply chain disruptions, high demand, or seasonal shortages can sometimes cause unexpected delays, so it’s always a good idea to discuss availability with your contractor early on.
During this stage, you’ll also finalize decisions on color selection, energy efficiency, and material durability, ensuring you choose options that suit your home’s aesthetic and long-term performance. Your contractor can provide samples and recommendations to help you make an informed decision. Overall, the material selection and ordering phase can take anywhere from one to four weeks, depending on your chosen materials and supplier availability.
Once materials are available and permits are approved, the next step is scheduling your roof installation. The timeline for this depends on several factors, including contractor availability, weather conditions, and the complexity of your roof design. Simple low-slope or single-layer roofs may be scheduled quickly, while steep slopes, multi-layered roofs, or extensive structural work may require more preparation.
Another key factor is the seasonal demand for roofing services—spring and fall are the busiest times for roofing companies, which may mean a longer wait for an available installation slot. In most cases, homeowners can expect the scheduling and prep process to take one to two weeks before work begins.
The actual roof installation process is often the shortest phase of the project, typically lasting between one and seven days, depending on the size and complexity of the roof. A standard asphalt shingle roof on a 1,500–2,500 sq. ft. home can often be completed in one to two days, while a roof with more square footage or an intricate roof may take up to a week in total.
The process starts with removing the old roofing materials. Then, the roof deck is inspected to check for structural damage. If the deck is in good condition, the team installs underlayment, new shingles, flashing, and ridge vents to ensure proper water drainage and ventilation.
Due to the precision required, installation takes longer for more complex materials like metal or slate. Weather can also impact this phase—if heavy rain or extreme heat occurs, your contractor may pause work to maintain safety and material integrity.
After installation, the roofing crew performs a final inspection to ensure everything is installed correctly and meets quality standards. This includes checking for proper sealing, secure flashing, and proper ventilation positioning. Any corrections, such as loose nails or other minor adjustments, will also be addressed.
Once the final check is complete, the cleanup process begins, which involves removing old roofing materials, excess debris, and stray nails from your property. Many contractors use magnetic sweepers to catch nails that may have fallen during installation, ensuring your yard and driveway are safe and eliminating any hazards that might affect homeowners or pets.
This final phase is typically completed within one to two days. If your new roof comes with a warranty, this is when you’ll receive any documentation outlining maintenance guidelines and warranty terms.
While most roof replacements stay on schedule, unexpected delays can occur due to hidden structural damage, poor weather conditions, contractor availability, or material shortages. If your roof has water damage, a compromised roof deck, or requires additional reinforcements, this can add days or even weeks to the timeline. Additionally, if a homeowner upgrades materials, adds ventilation systems, or makes mid-project design changes, this can also extend the process. Working with a reputable roofing contractor is the best way to minimize delays and keep clear communication throughout the project.
