What a Dundalk roof replacement actually includes
- Full tear-off down to the deck, with the layer count established before we quote rather than discovered afterwards.
- Deck inspection and replacement at a per-sheet price named in the proposal.
- Parapet, coping and party-wall detail — the joint that leaks most on an attached house, rebuilt and flashed properly rather than sealed over.
- Drainage: internal drains, scuppers or rear box gutter, cleared, re-flashed or rebuilt so water actually leaves the roof.
- Every penetration detailed individually, including roof-deck posts and pedestals, which are the single most common leak source on a city roof with a deck on it.
- Ventilation assessed and corrected. Exhaust without intake does nothing. An under-vented assembly shortens the life of the roof you are paying for.
- Edge metal and perimeter attachment specified for the exposure the house actually has.
- Full clean-up and magnet sweep, disposal included and weighed, permit pulled, workmanship warranty in writing.
What we install on a Dundalk roof
On the flat and low-slope blocks
Modified bitumen in a base-and-cap configuration, or single-ply TPO or EPDM membrane. Both are rated for low slope. Architectural shingle is not, and installing it on a roof that is nearly flat is the single most common way a Dundalk roof gets ruined by a contractor who only knows one system.
On the pitched blocks
Architectural asphalt shingle over synthetic underlayment, with ice-and-water membrane at the eaves, in the valleys and around penetrations, new step and counter flashing rather than reused metal, and a ventilation system that actually balances intake against exhaust.
Tear-off versus recover
Layer count is the variable that moves a Dundalk number most, and it is knowable before anyone quotes. We check it at the inspection so the number you get is the number, rather than a figure that grows on day two when the tear-off reveals what is really up there.
The party wall problem nobody warns you about
On an attached house, your roof does not end at a boundary that water respects. It runs into a shared wall, and the detail at that wall — flashing, coping, the mortar in the parapet — is doing as much work as the membrane in the middle of the roof. When it fails on your neighbour's side, the water shows up in your ceiling. When it fails on your side, it can show up in theirs.
This matters practically. If we inspect your Dundalk roof and conclude the entry point is on the other side of the party wall, we will tell you that, and we will show you the photographs that prove it, even though the outcome is that we do not sell you a roof that day. The alternative — replacing your perfectly serviceable membrane and watching the stain come back — is how homeowners end up believing every roofer is a thief.
What drives the number on a Dundalk roof
Roof area in squares, pitch, complexity, existing layer count, deck condition, penetrations and skylights, flashing linear footage, ventilation work, disposal weight, access and staging, material tier, and permit and review requirements. Those are the variables, and they are the reason a regional average is close to useless for your specific house. We have written the whole breakdown out, including how to read a quote and which line items to demand from every bidder: what drives roof replacement cost in the Baltimore area.
How it works
- Free inspection and photo report within 24 hours, with roof area measured rather than estimated, layers established, and deck condition assessed where it can be.
- A line-item proposal. Tear-off, decking at a named per-sheet rate, underlayment, flashing, ventilation, disposal, permit, warranty — itemised, so you can compare it against anyone else's bid line for line.
- Permits and any review handled by us, started early because that clock is usually longer than the construction clock.
- Installation, inspection, and a written workmanship warranty alongside the manufacturer's material warranty. MHIC #111971 and

Permits, jurisdiction and review in Dundalk
Dundalk work is permitted through Baltimore County's Department of Permits, Approvals and Inspections. Dundalk is unincorporated Baltimore County. County permits, county inspectors — not the city, even though the mailing address and the ZIP make it look like Baltimore to anyone unfamiliar with the line.
We pull the permit. If a contractor asks you to pull your own permit for roofing work, that is a signal about their licensing, not a convenience for you. We carry MHIC #111971 in Maryland, and the number is on every proposal so you can verify it before you sign.

Dundalk roof replacement questions
How long does a Dundalk roof replacement take?
Most residential roofs are a one to three day job once the crew is on site. What moves that is complexity, access, weather, and what we find when the old roof comes off. Permit and review timelines are separate and can be the longest part of the calendar, which is why we start them early rather than at the last minute.
What happens if the decking underneath is bad?
It gets replaced. What matters is that you knew that was a possibility before you signed. Our proposals name a per-sheet price for decking replacement up front, so if we find soft or delaminated sheathing you already know what it costs and nobody is renegotiating with your roof open. A quote with no decking line is a quote with a hole in it.
What does a roof replacement cost in Dundalk?
It depends on measurable things: roof area in squares, pitch, complexity, how many layers have to come off, deck condition, the number of penetrations and skylights, ventilation work, disposal weight, access, and material tier. We publish a full breakdown of what drives the number rather than a made-up average, and we give you a firm figure after the inspection rather than over the phone.
Do you handle the permit in Dundalk?
Yes. Dundalk is unincorporated Baltimore County. County permits, county inspectors — not the city, even though the mailing address and the ZIP make it look like Baltimore to anyone unfamiliar with the line. We pull it, we schedule the inspections, and the licence numbers are on the proposal.
Can you match what the neighbours have?
Usually, and on an attached house it is worth caring about because the difference is permanent and visible from the street. Where the roof is genuinely shared or continuous across units, coordinating with the neighbours produces a better roof for less money per household than doing it piecemeal.
