Commercial Roof Replacement

New Roofing Systems for Maryland Businesses

When repairs are no longer the right solution for your commercial property, a properly installed replacement roof protects your investment, reduces ongoing maintenance costs, and gives your building a fresh start. Legacy Contracting Group guides business owners and property managers throughout Carroll County, Montgomery County, and the surrounding areas through the replacement process.

As a licensed and insured Maryland roofing contractor, we’re committed to bringing clarity and quality workmanship to every commercial roof installation we complete.

Roofing Systems We Install

We install a range of commercial and low-slope roofing systems suited for small commercial buildings and multi-unit properties. The right system for your property depends on its structure, your budget, and your long-term goals.

TPO

A popular single-ply membrane that holds up well in Maryland’s climate. TPO offers heat-weldable seams, good UV resistance, and a reflective white surface that helps manage cooling costs through Carroll County’s warm summers.

EPDM

A durable rubber membrane that’s been the commercial roofing standard for decades. EPDM handles temperature extremes well and is a reliable choice for low-slope applications where long-term performance is the priority.

Modified Bitumen

A multi-layer asphalt system that performs well on roofs with heavier foot traffic or mechanical activity. It’s commonly installed on older commercial buildings in Westminster and the surrounding area that were originally constructed with built-up roofing systems.

Standing Seam Metal

For commercial buildings with some pitch, standing seam metal provides a long service life and a clean aesthetic. It’s a strong choice for retail and office properties where curb appeal matters alongside performance.

Many of the systems we install come with manufacturer warranties, providing you with added protection over the life of the roof.

When Roof Replacement Makes More Sense Than Repair

Not every aging roof needs to be replaced right away, but at some point, continued repairs become more expensive than starting fresh. Here are some situations where replacement is often the better investment:

Repairs are becoming frequent, and costs are adding up
The roof is at or past the end of its expected service life
There is widespread membrane deterioration
There is water damage to insulation or structural components
You're planning significant renovations

If you’re unsure whether repair or replacement is the right call, we’ll give you an honest evaluation based on the actual condition of your roof.

What to Expect During a Commercial Roof Replacement

Understanding the roof replacement process ahead of time makes the project easier to manage, especially when your commercial property is in use.

Roof Removal

We begin by removing the existing roofing materials to expose the deck below. This allows us to identify and address any underlying damage before the new roofing system is installed.

Decking Assessment and Prep

Any damaged or compromised decking is repaired or replaced before installation begins. A solid substrate is the foundation of a long-lasting roof.

Roof Installation

The new roofing system is installed with attention to waterproofing, drainage, ventilation, and flashing details — the areas where most roofs fail prematurely.

Final Inspection

We complete a thorough review of the finished installation before the project is closed out, confirming that everything is properly sealed and performing as it should.

Frequently Asked Questions

How long does a commercial roof replacement take?

The timeline depends on the size of the building, the roofing system being installed, and the weather. We'll give you a realistic project timeline as part of your estimate so you can plan accordingly.

Can a building stay occupied during a roof replacement?

In most cases, yes. We work to minimize disruption to building operations and tenants. Specific access needs and noise considerations are discussed before the project begins.

What’s the lifespan of a new commercial roof?

It depends on the system. TPO and EPDM roofs typically last 20 to 30 years with proper maintenance. Metal roofing can last significantly longer. We'll help you understand the long-term value of each option.

Do your commercial roofing systems come with warranties?

Many of the systems we install are backed by manufacturer warranties. We'll walk you through the coverage details for the system you choose.

Is a commercial roof replacement covered by insurance?

It depends on your insurance policy. Many do cover roof replacement when it’s needed due to certain roof failures, such as storm damage.
