When considering a commercial roof replacement on a food manufacturing or processing facility, it's important to select a high-quality, robust roofing system. At Design-Pro we understand how vitally important it is to keep plants running — even a minor shutdown to deal with a roof issue could cost millions in production loss.

Industrial roof replacement can be tricky for your average roofer. Harmful chemicals or product waste are often emitted onto the roof surface, causing it to deteriorate and fail prematurely. Our custom design team uses scientific data analysis, coupled with years of R&D, to determine exactly what's best for your facility.

Warehousing
In any warehouse operation there's always millions of dollars of inventory sitting directly under the roof — inventory that can't afford to be contaminated by water let in by a faulty system. We encourage owners to talk with our design team to determine a preliminary solution based on the inventory being housed.

Innovative Services
Our approach is built on innovation and precision.
A roof replacement shouldn't be a copy-paste job. Every system we build starts with a deep dive into your building's specific DNA — its structural load, climate controls, weather risks, and long-term operational goals.
01
01Custom Design Roof Replacement
Custom Design Roof Replacement
A roof replacement should never be a one-size-fits-all solution. A true custom design begins with a comprehensive assessment of your building's unique characteristics. We collect real-time rooftop data to gain a complete understanding of your roof's condition, performance, and specific requirements.
Our solutions team then evaluates this data using a proprietary, science-based analysis developed from decades of hands-on experience and extensive rooftop evaluations. This proven approach allows us to design a roofing system tailored to your building's needs, helping maximize performance, longevity, and value.

02Re-Roofing Applications
Re-Roofing Applications
When the existing roof deck and insulation are still in good condition, a recover overlay can be a smart, cost-effective alternative to a complete tear-off.
Many roof decks and insulation systems can last 50 to 70 years, often outlasting roofing membranes such as TPO, PVC, and EPDM. When these underlying components remain structurally sound, installing a new roofing system over the existing roof can provide excellent long-term value.
A recover overlay reduces landfill waste, minimizes disruption to your building's operations, and lowers installation costs compared to a full roof replacement. In many cases, it can also improve weather protection and extend the overall life of your roofing system.

03Roof Life Extension
Roof Life Extension
The most cost-effective roof is often the one you don't have to replace.
Many building owners ask, "What's the best way to get the most life out of my roof?" The answer is simple: preventative maintenance.
Twice-yearly roof inspections are one of the smartest investments you can make. They help identify small issues before they become costly problems, protecting your roof and extending its service life.
Think of it as having a professional keep an eye on your investment. By taking a proactive approach instead of waiting for leaks or damage to appear, you can avoid unexpected expenses, maximize your roof's lifespan, and get the highest return on your investment.

Risk & Reward Benefit Analysis
Making Confident Roofing Decisions
Roofing decisions are major investments. That's why we take the guesswork out of the process with a clear, data-driven analysis of your options.
We compare the long-term costs and benefits of Repair, Restore, Re-Roof, or Replace, taking into account factors such as lifespan, maintenance, energy savings, and warranty coverage.
By looking beyond the upfront cost, we help you understand the true value of each option, so you can make the best decision for your building, your budget, and your long-term goals.
Step 02
Roof Assessment
This involves a custom roofing design team to examine your current roofing composition, performance and history. This examination helps to create a baseline for the initial Design-Process of your Custom Roofing Solution.
Step 03
Scientific Data Evaluation
This step of the process is where our Custom Design team takes over, utilizing their decades of leadership experience in the industry to painstakingly sift through rooftop data to determine which solutions best meets your needs.
Step 04
Accounting For All Building Factors
Design-Pro's Custom Design Team not only uses scientific rooftop data evaluation, they also consider all of the internal and external factors going on at your facility to come up with the best possible solution.
Step 05
Customer Design-Proposal
A member of Design-Pro's Custom Roofing Team will meet with you to discuss the determining factors of why they designed the roof to a specification.
Step 06
Our Skilled Roof Installation Process
Our experienced roofing technicians ensure that every aspect of the installation process is carried out to specification. Design-Pro custom roofing installation teams understand how to interoperate and execute the custom Design-Protocol.
Step 07
Final Inspection & Quality Assurance
Design-Pro places a strong emphasis on quality control throughout the entire installation process. They conduct thorough inspections and quality checks at various stages to ensure that the roof is being installed to the highest standards. This attention to detail not only ensures the durability of the custom roof but also contributes to your peace of mind.
Step 08
Final Walkthrough & Client Approval
Once the roofing project is complete, we'll schedule a final walkthrough with you to review the work and address any questions or concerns you may have. We want to ensure that you are completely satisfied with the final product and that your product meets national standards for quality compliance.

Common Questions
Everything You Need To Know Before We Get On The Roof.
01
How Do Commercial Roofing Partners Differ From Contractors?
A typical contractor is tied to one manufacturer and sells whatever material that relationship dictates — proven or not. A partner like Design-Pro isn’t tied to a single material. We design a system based on your facility’s actual internal and external conditions.
02
How Often Should My Commercial Roof Be Inspected?
Design-Pro recommends bi-annual inspections. A small cut, crack, or hole in the membrane can go unnoticed for years — by the time it’s found, water intrusion may have already compromised the whole system.
03
How Do I Know if My Business Needs Roofing Services?
Persistent leaks that return even after repairs are a red flag — often a sign the insulation and decking underneath are already saturated. That’s an all-hands-on-deck situation requiring immediate action.
04
What Are the Latest Trends in Commercial Roofing?
Trends come and go. If you’re investing in a new roof, choose a high-quality, proven system built to last — not whatever’s trending this year.
05
What Qualifications Should I Look for in a Roofing Consultant?
Many companies are selling you a new roof whether you need one or not. Design-Pro collects scientific rooftop data, analyzed by our technical services team, to determine what needs repair now versus what can wait.
06
How Can I Improve My Warehouse Roof’s Energy Efficiency?
The biggest factor is R-value insulation — R-15 or higher is typically sufficient. Roof color plays a smaller role than most assume, especially since reflective white roofs need regular cleaning to keep their efficiency benefit.
07
What Are the Most Effective Roofing Solutions Today?
Solutions vary widely by building and budget. Design-Pro recommends a high-quality, time-tested system over the newest option on the market.
08
Can a Damaged Metal Roof Be Repaired, or Does It Need Replacing?
Almost anything can be repaired. The real question is how long you want to keep chasing leaks and band-aiding a bigger issue. A full roof evaluation tells you which makes sense.
09
What Are the Most Common Issues in Roof Repairs?
Inexperience. A repair can look simple on video, but every roofing system is different, and each component has to work with the others — a mismatched repair method causes more problems than it solves.
10
What Factors Should Be Considered When Selecting a Roof Solution?
Everything — what’s happening inside the facility and the conditions surrounding it outside. We’ve seen premature roof failure result from a single overlooked factor a provider dismissed as “not a big deal.”
11
What Materials Are Used in Commercial Roofing?
TPO, EPDM, PVC, metal, and BUR (built-up roofing), plus fluid-applied silicone or acrylic coatings — typically used mid-to-late in a roof’s life to extend its lifespan.
12
How Do I Determine the Best Repair Solution?
A roof that’s 1–3 years old usually has a straightforward fix. Older roofs take more detective work from a trained professional. Skip the roof-in-a-can shortcuts — they mask problems and make them worse.
13
Are Storm Emergency Roof Repairs Available?
Yes — Design-Pro runs a 24/7/365 emergency storm response team, and we’ll help you negotiate with your insurance provider to restore like, kind, and quality as fast as possible.
