"the reason i got a metal roof if because i am an old lady and had been going up on the porch roof to shovel it. i figured that with a metal roof that the snow would slide off the roof as they advertise, well it doesn't slide off the back porch so i have to shovel it. scary"

"We hired Capital Construction for a complete residing of our historic farm house. The scope included the removal of the old cedar siding, necessary sheathing repairs, building wrap and the installation of James Hardie Fiber Cement Planks and new trim work. From the initial consultation with Capital Construction, the communication was clear and transparent. They provided a detailed, fixed-price quote with no hidden fees and clearly explained the materials, timeline, and warranty. The installation crew was incredibly meticulous. The quality of the finished product is flawless—the seams are clean, the caulking is neat, and the details around the windows and doors are precise. What impressed me the most was their attention to what you can't see: they took the time to properly install the weather barrier and trim, ensuring a long-lasting, watertight envelope for our home. We couldn't be happier with the results. Capital Construction has completely transformed the look and value of our home"

FAQs for roofing projects in Alton, NH

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

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. 

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. 

Yes, most states require roofers to be licensed, and for good reason. Hiring an unlicensed roofer could lead to poor quality work, costly future expenses, and potential code violations.

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

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?
