Raising the Roof: Everything You Need to Know
Replacing your roof is a significant investment. If this is your first time, you likely have questions about the process, what happens after removing old shingles, and factors that may affect the final price.
A comprehensive roofing proposal should answer your questions in advance. Understanding the components of a complete roofing system matters, as protection involves more than visible shingles.
Key Factors Affecting Residential Roofing Estimates
Home Size - The size of your roof is the biggest cost factor. Divide the roof surface area in square feet by 100 to get the roofing square number. Cost per square usually includes materials and installation.
Roof Materials - This is the most variable cost. Asphalt shingles are the most popular and typically cost the least. Metal, wood, slate, or solar roofing materials usually cost more.
Slope & Pitch - Steep roofs can be more labor-intensive, which may increase the estimate. The pitch and complexity of the roof may influence the roofing materials selected, which will also impact cost.
Where You Live - The area you live in, its cost of living, climate, local building codes, and permit requirements are variables that also factor into the cost of your new roof.
It Starts with Removing the Existing Roof
During most roof replacements, contractors remove old materials to inspect the underlying roof deck. This step is essential, as the deck’s condition cannot be accurately assessed until the previous system is removed.
Once shingles and underlayment are removed, the roof deck is inspected for soft spots, deterioration, moisture damage, or other issues that must be addressed before installing the new roof.
Additional costs may arise at this stage. Damaged plywood or sheathing is not always visible during initial inspections, so replacement is typically billed separately. Your proposal should specify how these repairs will be managed and their potential costs.
Before roofing work begins, we take steps to protect the areas surrounding your home. We carefully position heavy-duty tarps to shield siding, windows, doors, landscaping, shrubs, and other exterior features from falling debris during removal of the existing roof. Taking the time to protect your property is an important part of keeping the jobsite safe, clean, and well managed from start to finish.

With the new roofing system fully installed, the home is protected, and the property is returned to its original condition. Clean, cared for, and free of construction debris. A complete roof replacement should deliver more than a great-looking finished product; it should provide lasting protection and peace of mind for the homeowner.

A Roof Replacement Means More Than Just New Shingles
While shingles are the most visible component, they are only one part of the system that protects your home.

A full roof replacement may include the following, depending on your roof and project requirements:
Roof deck preparation to provide a solid, sound surface for the new roofing system.
Leak barrier and underlayment to provide additional protection between the roof deck and shingles in areas vulnerable to water and ice.
Drip edge along the roof perimeter to help direct water away from the roof and fascia.
Flashing around chimneys, walls, valleys, plumbing vents, and other roof penetrations where water intrusion is more likely to occur.
Shingles installed according to manufacturer specifications and the requirements of the selected roofing system.
Hip and ridge cap shingles to protect and finish the areas where roof planes meet.
Ventilation components that help regulate heat and moisture in the attic and support the performance of the roofing system.
Each component helps direct water away from your home, protect vulnerable areas, and ensure a durable roof.
Don’t Overlook Roof Ventilation
Ventilation is often overlooked during roof replacement, but it is an essential element.
A balanced attic ventilation system lets fresh air in through intake vents near the bottom of the roof, while warm, moist air escapes through exhaust vents higher up.
Insufficient ventilation allows heat and moisture to accumulate in the attic, which can damage the roof deck and materials and reduce the roof’s lifespan.
Roof replacement is an ideal time to assess your ventilation system. In some cases, replacing vents is sufficient; in others, upgrades may be recommended to improve airflow.
A balanced ventilation system requires equal intake and exhaust.

What’s Usually Not Included?
Understanding what is included in your initial proposal versus what may require additional work is essential.
Items such as gutter replacement, major ventilation changes, structural repairs, or skylight installation and replacement are typically outside the standard project scope, as are unforeseen roof deck repairs.
This does not indicate an oversight in the estimate; some issues only become apparent after removing old roofing materials.
Clear communication is fundamental. If unexpected issues arise, your contractor must explain the findings, the reasons for repair, and the associated costs before proceeding.
Cleanup Is Part of the Job
Roof replacement creates substantial debris. Cleanup must be included as part of the project.
All old roofing materials should be removed, and the work area thoroughly cleaned upon completion. This includes checking for nails and debris and removing dumpsters and leftover materials.
A professional roofing project should leave your property in the same condition as before the work began.
Understand Your Warranty
Before selecting a roofing contractor, inquire about manufacturer and workmanship warranties.
Manufacturer warranties cover roofing products, while workmanship warranties apply to contractor installation. Coverage, exclusions, and warranty periods vary, so it is important to understand your roof’s protection.
Verify whether your roofing system is required to meet specific manufacturer requirements, such as installation methods, materials, and ventilation, to qualify for warranty coverage.
Flexible Ways to Pay for Your New Roof
A roof replacement is an important investment in your home, and there are several ways to manage the cost depending on your circumstances.
Insurance
If your roof has been damaged by a storm, wind, hail, or another covered event, your homeowner’s insurance may cover some or all of the replacement cost, depending on your policy and the cause and extent of the damage. Your insurance provider can help you determine what coverage may apply and guide you through the claims process.
Financing
For homeowners who prefer to spread the cost over time, Advance Home Pros offers financing through Acorn Finance. Homeowners can explore financing options from a network of lenders, with amounts ranging from $1,000 to $100,000. The application takes about 60 seconds, making it easy to review available options without delaying your roofing project.
Credit Cards
Credit cards can also provide a convenient way to pay for all or part of your roof replacement. Depending on your card, you may also be able to take advantage of rewards or other benefits. Consider your card’s interest rate and terms when deciding whether this option makes sense for you.
Whichever payment method works best for your household, understanding your options ahead of time can make planning for a roof replacement a little easier.
Before You Sign a Roofing Contract
While price matters, it shouldn't be your only consideration when reviewing roofing proposals. What roofing materials and system are being installed? Does it explain how unexpected decking repairs will be handled? Are cleanup and disposal included? What warranties are offered? Who’s managing the project, and how will you be updated if anything unexpected comes up?
Roofing proposals may vary significantly in price due to differences in scope. Knowing what is included helps you compare proposals more accurately.
