Cracked Scupper Box
Water stains the wall right below where the roof drains out.
The scupper box has cracked, or its membrane flashing has split.
Hire a Chevy Chase commercial roof repair contractor that checks for historic overlay review before changing visible caps or gutters on older storefronts.



A Chevy Chase commercial roof repair contractor works in a business district near the Euclid Avenue and High Street intersection, where roofs drain through parapet walls. Some parcels sit in an H-1 overlay, so visible changes get checked first.
Before replacing parapet caps or gutters with a different material, we ask LFUCG historic preservation staff whether the parcel needs a Certificate of Appropriateness.

The scupper box has cracked, or its membrane flashing has split.
Plaster bubbles high on the inside of the front wall.
Coping caps have open joints along the top of the parapet.

The leader head below the scupper is clogged or too small for the flow.
Matching the existing material and color on visible caps and gutters avoids a review delay where the parcel sits in an H-1 overlay. Rebuilt scupper boxes and sealed coping keep water out of the old masonry.
Repairs that match the building keep both the roof and the storefront in order.
Rebuilt boxes and clear leader heads carry water off the roof and down the wall pipe.
Historic staff are asked before any visible material or color changes.
Before and after photos help if a review asks how a detail looked.
Shops, restaurants, and offices around Chevy Chase usually need one of these.

Scuppers, parapets, and historic overlay checks.
Cracked scupper boxes, open coping joints, and worn counterflashing cause most leaks in the Chevy Chase business district near Euclid Avenue and High Street, where roofs drain through walls. Repairs reseal or replace scupper boxes, recaulk or replace coping, and rebuild counterflashing.
Ask LFUCG historic preservation staff about an H-1 overlay before replacing visible caps or gutters with a different material.
It can. Properties in a Lexington H-1 overlay need a Certificate of Appropriateness before exterior work, and that can include replacing visible metal panels, flashing, or gutters with a different material or color.
H-1 overlay approval for roof repair out of sight on the roof is a separate question, so ask staff about the parcel.
Old caps come off, the wall top gets checked for loose masonry, and new caps go on with sealed joints and cleats. On a visible front wall, the profile and color get matched to what was there, which matters if the parcel sits in an overlay.
The leader head under a scupper clogs with leaves or is undersized for heavy rain, so water spills over and runs down the wall. Clearing it, resealing its joint to the scupper, and checking the downspout below fixes most overflow.
Boxes with small cracks get cleaned and resealed, and their membrane flashing gets rebuilt. Rusted-through or split boxes get replaced at the same size, with new membrane flashing tied into the roof.
The membrane repairs match whatever system is on the roof now, often modified bitumen or a newer single-ply over older layers. Visible metal at the parapet and gutters gets matched in profile and color, which keeps the storefront consistent and simplifies any overlay review.
Send the address and where the wall stains. We will check the scuppers and coping and confirm any overlay questions first.
