Emergency roof repair in Washington, DC

Move electronics, rugs and furniture out from under the water, and put a bucket or storage bin under the drip. If the ceiling plaster is bulging, poke a small hole at the lowest point with a screwdriver so the water drains into the bucket instead of bringing the whole ceiling down.

If water is near light fixtures or outlets, turn off that circuit at the panel. Do not go onto the roof in the dark or in lightning, especially on a rowhouse with a low parapet, and do not climb a wet ladder to a porch roof. Our post on steps to take while water is coming in covers the details.

Then call us. Tell us where the water is showing up, what kind of roof you have if you know, and how the roof is reached. That short conversation tells us whether to load a ladder for a front porch, a roof hatch kit for a rowhouse or saws and plywood for a fallen limb.

On a low-slope rowhouse roof, a tarp is often the wrong tool, because wind gets under it and parapets give us little to tie down to. We usually seal the opening with a self-adhering membrane or cut in a piece of compatible sheet, sealed at the edges. It holds until we can make a permanent repair in daylight.

On a pitched shingle or slate roof, we run a heavy reinforced tarp over the ridge so water sheds over it rather than under it, and fasten it with wood battens screwed through the tarp, not with nails punched through the field. On slate we avoid walking the surface in the rain and work from a ladder hook or roof jacks to keep from breaking more pieces.

When a limb has come through the deck, we cut it back to the roof line, lift what we can off the roof, frame over the hole with plywood and cover the opening with membrane or tarp. Large trees on the house may need a tree crew with a crane first, and we coordinate the order of work so nothing shifts after we dry it in.

Working on a roof at night is slower and riskier, so we light the work area, tie off to anchors or a sound chimney mass, and keep the job to what is needed to stop water. Permanent repairs wait for daylight and a dry surface, when we can see the damage clearly and bond materials properly.

Rowhouse blocks add their own wrinkle. If the only roof hatch is in your neighbor's house, or the alley ladder spot is blocked by a parked car, we may need a few minutes to sort out access. Having a hatch key ready and the top-floor hallway clear saves time when we arrive.

In neighborhoods with heavy tree canopy such as Chevy Chase DC and Woodley Park, most night calls involve limbs. We bring saws, extra plywood and longer ladders on those trips, because the damage is usually on a steeper roof than a rowhouse.

An emergency fix is meant to keep water out for days or weeks, not years. Tarps degrade in sun, and temporary membrane over a wet deck will not bond as well as new material on a dry, clean surface. We tell you how long the temporary work should hold and schedule the follow-up before we leave.

The permanent repair may be a simple seam weld or a few replaced shingles, or it may be decking replacement, new flashing and a larger membrane section. Once the roof is dry and we can open it up in daylight, we price the full fix and walk you through photos of what we found.

Insurers want to see what happened before anything was cleaned up. We photograph the roof opening, the debris, the interior water path and the temporary work, and we note the time and weather. That record is often the most useful thing you have when an adjuster calls.

We do not decide coverage, but we can give your adjuster a clear scope of the permanent repair and meet them on the roof. Our page on documenting the damage for your claim explains what we provide and what you should keep.

Hold on to receipts for buckets, fans, dehumidifiers and any emergency service. Many policies cover reasonable steps taken to prevent further damage, and those receipts support that part of the claim.
