What's included
TPO roofing
Heat-welded single-ply membrane, the most common choice for Maryland warehouses and retail buildings for its energy efficiency and cost.
EPDM roofing
Durable rubber membrane suited to Maryland's temperature swings, common on older commercial and multi-tenant buildings.
PVC roofing
Chemical- and grease-resistant membrane often specified for restaurants and industrial facilities with rooftop equipment.
Modified bitumen
Torch-applied or self-adhered multi-ply system used on smaller commercial roofs and additions across Baltimore and the DMV.
Standing-seam metal
Common on Maryland distribution centers and industrial parks for its long service life and low maintenance.
Recover vs. tear-off
A moisture-scanned existing roof that passes code load requirements can often be recovered rather than fully torn off, reducing cost and downtime.

FAQs
What roofing systems do Maryland commercial roofers install?
Most Maryland commercial and industrial buildings use low-slope membrane systems — TPO, EPDM, PVC, or modified bitumen — rather than shingles. Standing-seam metal is also common on warehouses and distribution centers.
How much does commercial roof replacement cost in Maryland?
Commercial roof replacement in Maryland typically runs $6–$14 per square foot depending on membrane type, insulation requirements, roof access, and tear-off scope. A 20,000 sq ft warehouse roof commonly falls between $120,000 and $280,000.
Do commercial roofers need an MHIC license in Maryland?
The MHIC license requirement applies to residential home improvement work. Commercial-only roofing contractors aren't required to hold an MHIC license, but you should still confirm business licensing, bonding, and current general liability and workers' compensation coverage before signing a contract.
What warranty should I expect on a commercial roof?
Manufacturer NDL (No Dollar Limit) warranties on TPO and PVC systems commonly run 15–30 years when installed by a certified applicator, plus a separate contractor workmanship warranty — get both in writing before the project starts.
Do Maryland commercial roofers handle re-roof over an existing membrane?
Many low-slope systems can be recovered rather than fully torn off if the existing roof passes a moisture scan and meets code load requirements — this can meaningfully reduce cost versus a full tear-off. Ask for a moisture survey as part of your estimate.
