Find Answers to the Most Common Questions

Do you handle both residential and commercial projects?

Yes. WDM Contracting works with both residential and commercial clients across New Jersey, handling everything from home exterior upgrades to larger, more complex commercial projects.

Can you manage multiple parts of a project, like roofing and electrical together?

 Absolutely. One of our biggest advantages is handling multiple trades in-house—including roofing, siding, electrical, and underground utilities—so you don’t have to coordinate separate contractors.

What types of roofing systems do you install?

We install a wide range of roofing systems including asphalt shingles, metal roofing, flat roofing systems like TPO and EPDM, and composite materials from trusted manufacturers like GAF, Owens Corning, and CertainTeed.

Do you offer electrical services and panel upgrades?

Yes. We handle exterior and service electrical work including new service installations, panel upgrades, subpanels, EV chargers, and smart panel systems for both residential and commercial properties.

Are you licensed and insured?

Yes. WDM Contracting is fully licensed and insured, giving you confidence that your project is handled professionally and in compliance with all local requirements.

How do I get started with a project?

Getting started is simple. Reach out to schedule a consultation, and we’ll review your project, define the scope, and provide a clear plan and estimate so you know exactly what to expect.

How long does a typical roofing project take?

Most residential roofing projects can be completed in 1–3 days, depending on the size, materials, and weather conditions. Larger or more complex projects may take longer, especially if additional work like decking repair or structural updates is needed.

Do you handle full roof and solar projects?

Yes. WDM Contracting can complete full roof replacements alongside new solar system installations—so you can upgrade both at the same time with one team managing the entire project. If you already have solar, we can safely remove your existing panels, complete your roof replacement, and reinstall your system once the new roof is finished. We also offer full solar decommissioning if you choose not to reinstall.
