Metal Roofs in Kensington, MD

When Montgomery County adopted the Vision of Kensington, its roof survey noted that a surprising number of houses in the district still had their original standing seam metal. Metal here is often an old roof to keep before it is a new roof to buy.

Roof by roof

Four kinds of Kensington roof and where metal sits on each

Shares come from the district plan's own survey of the historic district, plus one Census figure for the apartment side.

  1. Gabled houses69 percent of residential buildings

    The plan calls the gable the dominant roof form here, with end gables, cross gables and elongated gables on the Queen Anne and Shingle houses. Those roofs meet at valleys, dormers and bays, so a metal question on one of them is really a question about many joints.

    The plan adds that most buildings have received replacement roof cladding, so the covering you see may not be the first one.

  2. Hipped houses38 buildings, 27 percent

    These are the Bungalow and American Foursquare houses of the district. A hip has no gable ends, which makes the roof a plainer shape, and the same preserve-first reading applies to whatever covers it.

  3. Porch roofsall but 16 percent have a porch projection

    The survey puts 33 percent of dwellings at a partial or full front porch with fan brackets and turned spindles, 26 percent at a wrap-around porch and 22 percent at a one-story entry porch. A porch roof is small, sits low and is seen from the sidewalk, which is why a metal porch roof draws more attention than its size suggests.

    It is also the roof most likely to be a separate question from the main roof, so the two can need different answers.

  4. Apartment buildings41.5 percent of homes sit in 5+ unit buildings

    These roofs are mostly low-slope, so the metal conversation barely starts; see the flat roof guide instead. The Census counts these homes by building size, not by whether they lie inside the district line, so the parcel decides which office is involved.

What the county says

Keep it, match it, or ask first

The county's design guidelines for historic sites and districts list standing seam metal among the traditional roof materials, beside slate, wood shingle and tile. One photo caption goes further: a metal seam roof is a traditional material and should be preserved and maintained.

Guideline 5.4 asks owners to preserve original roof material and replace it with similar material only when necessary. Guideline 5.5 encourages replacement in kind and asks that new material match the original in scale, color and texture as closely as possible.

District rules

An asterisk beside Kensington

The marking

In the guidelines' list of districts, Kensington carries an asterisk, which the note defines as having district-specific guidelines of its own.

The tie-break

The county text may supplement a district plan, and where the two conflict the district-specific guidelines prevail.

The plan itself

The Vision of Kensington was prepared in August 1992 and adopted by the County Council on November 4, 1997.

Nothing in the plan text read for this page rules metal in or out. It records the roofs that were there, which is the baseline a reviewer would compare a change against.

Who decides

Metal jobs sorted by what you plan to do

Your planWho decides
Repair an old metal roof with the same material and designMontgomery Planning lists matching roof repairs as work that does not involve the Historic Preservation Commission. Confirm the scope with the Historic Preservation Office, 301-563-3400.
Replace worn metal with new metal of the same lookThe guidelines encourage replacement in kind. Ask the Historic Preservation Office whether the job counts as a repair or needs a Historic Area Work Permit.
Replace shingle or shake with metalThat is a change of exterior material, which the HAWP list names. Call the Historic Preservation Office before any material is ordered.
Replace original metal with another coveringThe same list applies, and the district plan's note about original seam roofs is the context a reviewer has on file.
House outside the historic districtNo commission step. The Town and county questions on the Kensington page still come first.

The permit page also names Kensington among places where the municipality may review changes before the HAWP application, so the Town call comes first. For metal in general, see metal roofing compared; for neighbors, Silver Spring and Rockville.

FAQ

Kensington metal roof questions, from the plan to the porch

Does the Vision of Kensington mention metal roofs?

Yes. Its roof survey says most buildings have replacement cladding but a surprising number of houses retain their original standing seam metal.

Is a 1997 plan still the guide for a Kensington roof?

The county's guideline list still marks Kensington as having district-specific guidelines. Ask the Historic Preservation Office which documents it applies to your house.

Does the plan count how many metal roofs remain today?

No count is printed here. The plan gives a description, not a current number, so a roof's own condition is the better guide.

Is patching a metal porch roof treated like a repair?

Montgomery Planning lists roof repairs with matching materials and design as work outside commission review. Whether your patch qualifies is a question for its staff.

Would metal over a shingle porch roof count as a material change?

The HAWP list includes changes to exterior materials, and a covering swap looks like one. Ask before ordering.

Why do porches matter to a metal roof discussion here?

Only 16 percent of surveyed houses lack a porch projection, so porch roofs are part of nearly every street scene the district protects.

Does the guideline text recommend metal for a new roof?

It lists standing seam metal as traditional and asks that replacements match the original, so the starting question is what was there before.
