Historic roof and box gutter repair in Mount Pleasant (20010)

Because the whole neighborhood is a historic district, we start every job by asking one question: can this part of the roof be seen from a public street? On many blocks of Lamont, Kenyon and Newton Streets, the slope of the hill means rear roofs show from the street below, so the answer is not always obvious.

When work is visible, we gather photos, measure the existing materials and write a scope that puts back matching slate, metal or trim. Preservation staff can often sign off on in-kind repairs quickly. Changes in material, a new skylight or a rooftop deck take longer and may need a hearing.

Our permit and historic filing guide covers the process citywide. We still check current requirements for each address, because rules and staff guidance shift over time.

• Photograph each elevation from the street and alley
• Record slate size, metal profile, gutter shape and trim details
• Submit the scope to preservation staff with product data
• File the DOB permit once the visible work is cleared

Many Mount Pleasant rowhouses have a built-in gutter sitting behind the front cornice, lined with tin or copper when the house was built. Over decades, the lining splits at the seams, gets patched with tar and starts holding water instead of moving it. The leak shows up inside the front wall or along the top of the bay window.

We strip the old lining down to the wood trough, replace rotted boards and reline in soldered copper or a fully adhered membrane, depending on what the preservation staff expects and what you prefer. A new outlet and downspout connection at the end of each run finishes it. Our box gutter repair page shows how the relining goes together.

Victorian rows near Mount Pleasant Street carry slate on short front mansards, while Wardman-era porch-front rows to the north have low-slope porch roofs and simple cornices. Both styles share flat main roofs that drain to the rear, often toward alleys that drop steeply downhill.

The neighborhood's early twentieth century apartment buildings, some with decorative cornices along Park Road and Mount Pleasant Street, have larger flat roofs with internal drains. Those buildings usually need drain cleaning, curb flashing and membrane work planned with a condo board or building manager. We cover that in our multifamily roofing work.

Steep alleys behind Hobart Place and Irving Street make debris trailers hard to park. We often stage from the uphill end, lower debris by rope and carry roll goods by hand. Homes backing onto Rock Creek Park sit under tall trees, so gutters and scuppers there fill with leaves every fall and need clearing before winter. Where a downspout runs into an old terra cotta drain at the base of the wall, we check that it still flows, since a blocked boot backs water up into the gutter above.
