The offer

Twenty minutes on your roof. A written report you can hand to your board.

Most commercial roof decisions get made with bad information — a verbal "it's got a few years left," or a bid with no scope behind it. The condition report exists to fix that, whether or not you ever hire us.

STEP 01

We walk the roof

A roofing lead comes out, walks the field and the perimeter, and documents seams, flashings, penetrations, drains, curbs and ponding areas with photos.

STEP 02

You get it in writing

A short written report: system type and approximate age, condition by area, the specific defects we found, and what's urgent versus what can wait.

STEP 03

You get real numbers

Budget ranges for repair, restoration and full replacement — so you can build a capital plan or take three defensible options to your board.

What's in the report

  • Roof system identified — TPO, EPDM, PVC, modified bitumen, BUR or metal
  • Photo documentation of every defect we find, keyed to a roof plan
  • Drainage and ponding assessment
  • Flashing, curb, penetration and perimeter condition
  • Remaining service life estimate
  • Repair vs. restore vs. replace — with budget ranges for each
  • Warranty options available on a new system

Our work

Flat and low-slope roofs are the whole job here.

Not a residential shingle crew that also "does commercial." Membrane systems, mechanical penetrations, occupied buildings and phased schedules.

Systems & services

What we install, restore and repair.

TPO

Reflective single-ply, heat-welded seams. The default for most DMV low-slope replacements.

EPDM

Rubber membrane, fully adhered or mechanically attached. Proven on older commercial stock.

Chemical- and grease-resistant single-ply. Restaurants, kitchens, industrial exhaust.

Modified Bitumen

Torch, cold-adhered or self-adhered multi-ply for high-traffic and small complex roofs.

Built-Up & Coatings

BUR repair, and silicone or acrylic restoration coatings that extend a sound roof instead of replacing it.

Low-slope metal repair, re-fastening, seam sealing and retrofit over existing panels.

Full replacement

Tear-off or recover, new insulation to code, new membrane and warranty.

Restoration & coatings

Extend a sound roof 10–15 years at a fraction of replacement cost.

Leak repair

Find it, document it, fix it — and tell you honestly if it's a repair or a symptom.

Maintenance programs

Scheduled inspections and minor repairs that keep warranties intact.

Where we work

Washington, DCThe District has more commercial flat roof per building than almost anywhere in the country — a consequence of the Height Act — and a permitting and historic review layer that punishes contractors who have not worked here.Permits & costs → Montgomery County, MDMontgomery County runs one of the more demanding permit and energy code regimes in the region.Permits & costs → Prince George's County, MDPrince George's has the largest concentration of big-format industrial roof area inside the Beltway.Permits & costs → Howard County, MDHoward County's commercial stock is unusually uniform in age — and that means an unusually large share of it hits end of roof life at the same time.Permits & costs → Anne Arundel County, MDAnne Arundel puts two very different roofing problems in one county: a protected historic waterfront city, and a high-volume industrial corridor around BWI.Permits & costs → Frederick County, MDFrederick has two permit counters, one of the largest historic districts in the country, and a life-science corridor with roofs that need specific membrane chemistry.Permits & costs → Baltimore County, MDBaltimore County has some of the oldest industrial roof stock in the region, and a permitting authority that is entirely separate from Baltimore City.Permits & costs → Arlington County, VAArlington is dense, vertical and permit-efficient.Permits & costs → Alexandria, VAAlexandria is the DMV jurisdiction where the historic review process most often determines the roofing schedule.Permits & costs → Fairfax County, VAFairfax has the largest commercial office inventory in Northern Virginia, and a very large share of it was built in one twenty-year window.Permits & costs → Loudoun County, VALoudoun contains the densest concentration of mission-critical roof area in the world.Permits & costs → Prince William County, VAPrince William is where the region's big-box distribution and retail roof area is still growing — and where roofs from the last building boom are now old enough to need decisions.Permits & costs →

Straight answers

Questions we get before the first call.

Is the 20-minute roof report really free?

Yes. We walk the roof, document what we find and send you a written report with photos and budget ranges. There's no charge and no obligation to hire us. We do it because most commercial roofs we're called about turn out to need less work than the owner feared — and being the firm that told them so is worth more than a fee.

How fast can you get someone out for an active leak?

Call 202-798-7663. Active leaks get triaged ahead of assessments — we'll tell you honestly on the phone when we can be there and what to do to protect the interior in the meantime.

Do I need a full replacement, or can the roof be restored?

It depends on the condition of the insulation and deck under the membrane, not just how the surface looks. If the substrate is dry and the membrane is sound, a restoration coating can add ten to fifteen years for a fraction of replacement cost. If there's saturated insulation, coating over it just buys an expensive delay. The condition report tells you which situation you're in.

Can you work around tenants and building operations?

That's the normal case, not the exception. Occupied buildings get phased scopes, staged material handling, protected access paths, coordination with your mechanical trades, and a schedule your tenants get notified about in advance.

What does a commercial roof replacement cost in the DMV?

It moves with system type, insulation requirements, deck condition, access and how much mechanical equipment has to be lifted and reset — which is why anyone quoting a number sight-unseen is guessing. The report gives you a real range for your specific roof, and we'll break out repair, restoration and replacement so you can see the tradeoff.

Who is DMV Commercial Roofing?

We're the commercial roofing brand of Wanamaker Group LLC, the same Washington, DC company behind our sister firm Karma Construction Group — a licensed general contractor building throughout the mid-Atlantic since 2012. Coming out of a GC is why we're comfortable on roofs with structural, mechanical and envelope issues tangled together, and why we won't sell you a membrane over a problem that isn't a membrane problem.
