Frequently Asked Questions

How much does roof repair cost?

The cost of roof repairs depends on the type of damage, roofing materials, and the size of the affected area. Minor repairs, such as replacing a few shingles, may cost a few hundred dollars, while more extensive issues like leaks or structural problems can be significantly more expensive.

The most reliable way to get an exact estimate is to schedule an inspection. At DNB Construction, we provide detailed estimates so you understand the scope of work before any repairs begin.
How long does a roof repair take?

Most roof repairs can be completed in a single day. Simple jobs like replacing shingles or repairing flashing often take only a few hours. Larger projects, such as storm damage or structural repairs, may take longer depending on weather and materials.

Our team works efficiently to ensure every repair is done properly while minimizing disruption.
When should I replace my asphalt shingle roof?

Asphalt shingle roofs typically last 20 to 25 years with proper maintenance. Signs it may be time for replacement include recurring leaks, curling or sagging shingles, and significant granule loss.

If you’re unsure whether repairs are sufficient or a full replacement is needed, DNB Construction can inspect your roof and provide a clear recommendation.
How long do metal roofs last?
How long do asphalt shingle roofs last?

Most asphalt shingles last about 20 to 25 years, though factors like installation quality, ventilation, and storm exposure can affect their lifespan. Architectural shingles generally last longer than standard 3-tab shingles. Regular inspections help catch issues early and extend the roof’s service life.

DNB Construction offers free inspections to help homeowners assess the condition of their roof.
How often should I have my roof inspected?

It’s recommended to have your roof inspected at least once a year, ideally in spring or fall. You should also schedule inspections after heavy storms, strong winds, or hail. Routine checks help identify minor problems early, saving money and prolonging the life of your roof.

Contact us today to schedule your free inspection.
What does a roof inspection consist of?

A roof inspection includes reviewing shingles or other roofing materials, flashing, gutters, vents, and the overall roof structure. Inspectors look for leaks, wear, and hidden issues that aren’t visible from the ground.

At DNB Construction, we provide a detailed report so you know what requires immediate attention and what can be monitored over time.

Honest Pricing

Buying a roof is a major purchase, and there is nothing worse than getting overcharged. We promise to do a complete review of your project, prepare a professional and accurate bid, and stand by our commitment. We won’t always be the least expensive, but we will certainly be the best value.

Awards & Certifications

We have earned countless awards and certifications for our work in the industry. They come from top suppliers, service companies, safety organizations, government agencies, private companies and property owners we’ve partnered with over the many years in business. We value these accomplishments in much the same way we value you as a satisfied customer. It means we’re doing something right.

Insurance Claim Assistance

Sometimes one broken shingle can lead to a full roof replacement by your insurance company. That means little or no cost for you. But, BEWARE of scammers out there that will make promises they have no intention of keeping. Our experts will help with the inspection, documentation and submission of your claim, but will never ask you to give up control of that claim or pay in advance. We’ll work with you and your adjuster to achieve the very best outcome and accept payment only after the work is completed. This insures we’re 100% invested in your project and you have the peace of mind knowing you’re in good hands.

Warranties & Guarantee

We stand by our work. We offer a 50-year manufacturer’s materials warranty and a transferrable 25-year workmanship warranty as a Master Elite contractor for GAF. Master Elite status is only achieved through proper training and a history of adherence to strict installation practices. You shouldn’t have to worry about your investment in a new roof, and now you won’t have to.

Quality of Work

To us, this simple statement goes well past our abilities to provide you with a quality roof, it refers to our extensive history in the business, high level of communication, attention to detail, accountability when something goes wrong, and a promise to fix it immediately and professionally.

Job Site Conduct

Your home is a special place, and we don’t take that lightly. From start to finish, our crews take great care to maintain a clean and protected work environment for your safety and peace of mind. We will ensure your home and landscaping is protected throughout the job with specialized equipment to minimize debris, protect your home and landscaping from damage, and avoid injuries.
