Commercial Roof Repair and Replacement

Local businesses rely on us for commercial roof repairs, replacements, and new installations. Our commercial team works directly with building owners and managers to create solutions for flat and low slope systems.

We install TPO, EPDM, and PVC roofing for offices, warehouses, retail spaces, and industrial sites.

TPO Roofing

TPO works well for commercial buildings because it reflects heat and stands up to UV exposure. We install new TPO systems, replace aging membranes, and repair punctures, seam issues, and storm related damage.

EPDM Roofing

EPDM offers long service life and strong performance during temperature swings. Our team installs EPDM for new projects, replaces older systems that have reached their limit, and provides focused repairs for leaks or surface damage.

PVC Roofing

PVC supports buildings that face chemical exposure or areas with frequent standing water. Restaurants, shops, and industrial properties often choose this system.

We handle PVC installs, full replacements, and repairs that extend the life of existing membranes.

Frequently Asked Questions

How much does roof repair cost?

The cost of repairing a roof depends on the type of damage, the roofing material, and the size of the area that needs work. Small repairs, such as replacing loose shingles, may run a few hundred dollars.

Larger concerns, including leaks or damaged decking, can be more costly.

The most accurate way to determine the price is to schedule an inspection. DNB Construction provides clear, detailed estimates before any work begins.
How long does a roof repair take?

Most roof repairs are completed in a single day. Simple tasks, such as shingle replacement or flashing adjustments, often take only a few hours. Repairs involving storm damage or structural issues may take longer based on materials and weather.

Our crew focuses on efficient, careful work to keep the repair process smooth and effective.
When should I replace my asphalt shingle roof?

An asphalt shingle roof typically lasts 20 to 25 years. If you see persistent leaks, widespread granule loss, curling shingles, or early signs of sagging, it may be time to consider a replacement.

If you are unsure whether your roof needs repair or replacement, DNB Construction can inspect it and guide you through your options.
How long do metal roofs last?
How long do asphalt shingle roofs last?

Asphalt shingles usually last about 20 to 25 years. Lifespan depends on proper ventilation, installation quality, and exposure to storms. Architectural shingles typically last longer than basic 3 tab shingles. Routine inspections help extend their life.

We provide free inspections to help you understand your roof’s condition.
How often should I have my roof inspected?
What does a roof inspection consist of?

A roof inspection includes reviewing the condition of shingles or other roofing materials, flashing, gutters, vents, and the structural components of the roof.

Inspectors check for leaks, soft spots, and hidden issues you cannot see from the ground.

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.
