"I found Supreme Remodeling here on Angi. I interviewed several contractors and chose them mostly because of YOAV their representative I met with. He was the only one who offered design ideas at the initial meeting. I wanted to build an ADU. They handled everything from design to permits. As an added bonus their bid was the lowest by quite a bit.😁😁 I would 1000% recommend Supreme Remodeling and especially Yoav, he’s a real gem."

The cost to replace your roof is often significantly more expensive than the cost to repair it. On average, homeowners will spend between $5,890 and $12,800 to replace a roof. The size of the roof, the roof’s pitch, and the number of stories the house has will significantly affect the overall cost. You can expect to spend upwards of $46,000 for large, high-end roofs.

This all depends upon size, type and complexity of the actual sloped areas of the roof. An accurate estimate with detailed lists of covered and additional items is imperative when purchasing and protecting yourself during the process.

Roofing is a highly skilled and labor-intensive trade. Because of this, you can expect to pay an average of $2 per square foot for your roofing professional. Roofing labor costs generally make up about 60% of the overall project cost.
Answered by Angi Experts
Typical roofing repairs cost between $380 and $1,800 on average. However, most homeowners spend approximately $1,100 on a roofing repair project. The size of the roof, the extent of the damage, and the type of project all impact the final cost. External factors like product availability and supply chain issues may also affect the price.
Projects like repairing damaged gutters will only be around $180 to $560, whereas repairing a sagging roof will be a higher expense at $1,500 to $7,000.

Roof repairs start at around $700.00 and go up from there. There are many significant factors that come into play, and each customer's needs will rarely be the same.

Repair costs in this area are around $1,500.
Answered by Fidel Cruz at C39 Roofing in San Marcos, CA on 01/07/25
Repair costs are affected by geographic location such as ice & water underlayment requirements in the North and hurricane durability requirements in the Southeast. Other things that affect the cost are quality of materials, layers of tear-off, condition of the decking, and the style and pitch of your roof. Ask contractors to explain their price if they are higher, they are likely being more honest about what the replacement requires.
Answered by Michael E. Voelker at ProCrafters Roofing in Allison, IA on 01/06/25
Although not every state issues licenses for roofing pros, it's important to check with your county or city if hiring a licensed roofing contractor is necessary.
Hiring an unlicensed roofer might result in low-quality work and potential legal issues if an accident happens. It’s always best to check the qualifications and licenses of your roofer before they begin a project.

Before hiring a roofing contractor to work on your project, there are a few things you will want to ask, including:
Do you use roofing subcontractors?
Do you offer a warranty?
Do you have any references?
How will you clean up after the project is complete?
Will you remove my old or damaged roof?
Answered by Angi Experts

How long have your crews been working with you?
Do you offer a warranty?
Do you have any references?
How will you clean up after the project is complete?
Will you remove my old or damaged roof?
Answered by Scott A Margiano Sr. at Calvary Remodeling LLC in Shelton, CT on 01/09/25
How long should this product last in my area and does the manufacturer stand behind the product for that length of time?
What is the difference between manufacturer and contractor warranty?
Do you have any references?
Answered by Scott Perkins at Strive Roofing in Mesa, AZ on 01/07/25
Will you remove my old or damaged roof?
Will the roof you install be warrantied against black streaks?
Will the roof you install last as long as the warranty? Or will it only last about half as long?
Answered by Tracy Badra at Community Construction in Lansing, MI on 01/07/25
Does your company have multiple locations? This will let you know if they are truly local or a large company briefly working your area after a storm.
Do you offer a workmanship warranty? Confirm in writing the time length and details of such warranty.
Do you have quality reviews? All roofing contractors have references of their successful jobs. Good contractors won't have many negative reviews.
How will you protect our windows, siding and landscaping?
Will you remove my old or damaged roof?
Some disqualifying signs to look for are:
-Did the contractor cold call or knock on your door?
-Does the contractor look or talk like a salesman?
-Does the contractor have profiles on many different websites? Poor contractors will avoid an online presence to avoid bad reviews.
