MD VA Roofing

Roofing contractors in Dundalk, Maryland

Rowhouses share a roofline, which means a roof here is rarely one household’s decision alone.

What Dundalk roofs are dealing with

Much of Dundalk went up in the 1920s and again during the war, a great deal of it as attached and semi-detached brick housing. Where a roof runs across several units, water that gets in at one address travels, and a repair that stops at a property line frequently does not stop the leak. Flat and low-slope sections are common on this housing type, and they need a different material and a different crew than a pitched asphalt roof.

Turner Station, Colgate, Graceland Park and St. Helena hold much of the 1920s and wartime housing, a great deal of it attached or semi-detached brick. Flat and low-slope sections are common on this housing type. Newer infill elsewhere in Dundalk follows conventional pitched construction.

If you are not sure how much life is left in what is up there, the roof age check walks through the envelope one part at a time.

Roofs rarely give out in the open. They give out at the seams. Which is why the first question about any leak is where two things meet.
Garage Point 1: ridge caps 1 Ridge caps: thin, exposed, first to lift Point 2: the field of the roof 2 The field: granules and age Point 3: valleys 3 two slopes Point 4: flashing 4 where the garage meets the wall Point 5: vent boot 5 Vent boot Point 6: eaves and ice dams 6 Eaves, where backed-up water gets in
  1. 1 Ridge caps. Thin, fully exposed, and the first course to lift.
  2. 2 The field. Granule loss is the honest measure of how much life is left.
  3. 3 Valleys. One channel taking the runoff of two slopes, all year round.
  4. 4 Flashing. At the chimney, and where the garage roof meets the wall of the house.
  5. 5 The vent boot. Small, rubber, and on a much shorter clock than everything around it.
  6. 6 Eaves. Where water that has backed up at the edge gets under the courses.

When the work happens in Dundalk

Coordinating neighbors adds time that weather does not. Where a roof runs across several attached units, agreeing the scope takes longer than the work itself, and the households involved rarely arrive at the decision at the same moment. Warm months carry the work; the conversation that precedes it is worth starting a season ahead.

What moves the price in Dundalk

Low-slope and flat sections need a different material and a different crew than pitched asphalt, and a quote that prices the whole roof as one thing is usually missing that. The second cost question on attached housing is where the work stops: water that gets in at one address travels, and a repair that ends at a property line frequently does not end the leak.

The price moves on four things, and the brand of shingle is not one of them. If two or three quotes are already in front of you, the comparison checklist lines them up:

  • Is the step flashing along the walls being replaced, or cleaned up and sealed back down?
  • What does a sheet of decking cost, and how many sheets does the price assume?
  • Where does the ice-and-water shield stop?
  • Who covers the labor if something fails, and for how long?

The work

Before you call anyone in Dundalk

Four questions come up on nearly every roof across Maryland and Virginia, and the answer in Bowie is the answer in Fredericksburg. They are written out once, in the guides:

Why roofs fail here

Four failures do most of the damage across Maryland and Virginia, and there is a page on each. The stain on the ceiling is almost never under the hole.
