Roofing and restoration for Ellicott City homes
The Historic District sits in the narrow Tiber valley where several deep stream valleys converge, the same convergence that produced the 2016 and 2018 flash floods, while the greater Ellicott City around it climbs seven hills of newer housing that shed a cloudburst in every direction at once.
In Ellicott City, water is the whole conversation
The old town sits just west of the Patapsco, and its flood record goes back to 1780.
The most recent floods, in 2016 and 2018, are the storms we build roof drainage around. The 2016 flash flood came out of six inches of rain in two hours, and the 2018 one out of more than eight inches in two hours.
In an ordinary year the rain spreads evenly across the calendar at three to five inches every month, with summers hot, humid, and full of thunderstorms.
More about roofing in Ellicott City
None of that is an insurance claim. It is why roof drainage in Ellicott City gets designed for volume rather than for average.
On the hillside lots, where the grade falls away fast, water leaving the roof gets thrown clear of the foundation instead of dropped at the wall.
The nearest NOAA station, BWI, shows about 11 days a year with an inch of rain or more in its 1991-2020 normals. On a steep, cut-up roof that much water at once finds any gap at the drip edge or under aged underlayment first.
Great job on my roof in Glen Burnie. Handled all the insurance claim. Very good crew. No complaints the roof look great, great clean up as well. I highly recommend.
Two housing stocks in one zip code
Ellicott City is the county seat of Howard County, and its housing splits hard. The oldest buildings in town are in the historic district along Main Street, plus Tonge Row and the West End, and we see their bedrock right on the street: the granodiorite that outcrops along it and fed granite quarries here through the late 1800s and early 1900s. Roofs on those buildings are steep, cut up, and tied into masonry, so the work is counterflashing let into mortar joints, rebuilt valley metal, and detail work at every wall and chimney.
Out from the old core it is a suburb, and a long-running one. Normandy Heights went in as the first major subdivision in 1955, and the decades since filled the ground west to Marriottsville Road and south toward Columbia, along with the Route 40 corridor and its Koreatown stretch.
A mid-1950s house here is on its third roof by now, likely over plank decking, and the ventilation almost always needs correcting while the deck is open. A 1990s colonial on the other side of Centennial Road needs almost none of that.
Because the historic buildings sit on a street with no room for staging, work in the old town gets planned differently from a job in the subdivisions: where the dumpster goes, where material lands, and how the crew reaches the slope all get settled before the date is set.
Hail, wind, and the walls below the roof
The claim season in Howard County runs April into June, and most of the damage worth documenting does not show from the yard. We photograph it slope by slope, along with the dents in gutter apron and vent metal that date and size the storm, and write the loss in Xactimate.
Siding replacement in Ellicott City starts with the sheathing behind the panels, then rebuilds out from a properly lapped weather barrier with flashing at every opening.

Local Conditions
Common roofing challenges in Ellicott City, MD
- Cloudburst rainfall the drainage was never sized for: the July 30, 2016 storm dropped 6 inches of rain in two hours, and on May 27, 2018 the region took over eight inches in two hours
- Stone, granite, and brick structures along Main Street and Tonge Row where the roof, the flashing, and the masonry all have to work together, some of them standing since the milling era the Ellicott brothers started in 1771
- Steep, convergent terrain that sheds water fast, with the Historic District down in the narrow Tiber River valley immediately west of the Patapsco, where several deep stream valleys meet, and the town built on what are claimed to be seven hills
- Hard rock underfoot and against the slopes, since Historic Ellicott City sits on Ellicott City Granodiorite with outcrops lining Main Street, which limits how water can be routed away from a structure
- A climate of hot, humid summers with frequent thunderstorms and rainfall spread evenly at 3 to 5 inches every month, so there is no dry season in which a marginal roof gets a rest

About Ellicott City, Howard County
The historic downtown sits in the narrow Tiber and Patapsco valleys and has flooded again and again, and the whole area gets thunderstorm-heavy summers with rain through the year.
Up out of the valley, newer subdivisions climb granite hillsides on steep, complicated rooflines.
Ellicott City floods, and that record is why we design roof drainage here for volume. The historic downtown lies in the valleys of the Tiber and Patapsco and is prone to flooding from both, with major floods recorded as far back as 1780 and again in 1817, 1837, and 1868.
The water kept coming back through the 20th century, with major floods in 1901, 1917, 1923, 1938, 1942, 1952, 1956, 1972, 1975, and 1989. The most recent came in 2011, 2016, and 2018, and they are why valley metal on these roofs gets sized for the flow two planes dump into one channel.
The old town is built on stone, and that shapes where we send the water. Historic Ellicott City sits on Ellicott City Granodiorite, which limits how water can be routed away from a structure, so on the hillside lots we throw it clear of the foundation.
Some of the stone on Main Street goes back to the milling years. Three Quaker brothers from Bucks County, Pennsylvania, John, Andrew, and Joseph Ellicott, founded Ellicott's Mills here on April 24, 1771, upriver from Elk Ridge Landing, and it grew into one of the largest milling and manufacturing towns in the East. The town took the name Ellicott City with its 1867 incorporation charter and lost that charter in 1935.
In 1830 Ellicott City became the first terminus of the Baltimore and Ohio Railroad outside Baltimore, and the Ellicott City Station still stands as the oldest surviving railroad station in America. It is a National Historic Landmark built of locally quarried gray granite, the kind of masonry where roof work means counterflashing let into mortar joints.
Ellicott City is the county seat of Howard County and the most populous unincorporated county seat in the United States, and we reach it straight up from Columbia, which borders the CDP to the south at MD-108. The Patapsco River bounds it on the east and north and forms the Baltimore County line, and Ilchester borders it to the southeast at MD-104.
The climate is humid subtropical, with hot, thunderstorm-prone summers and rainfall spread evenly through the year.

Good to Know
Ellicott City roofing: frequently asked questions
My house is in the Ellicott City Historic District. Can you work on it?
Yes. The oldest structures in the district are stone, granite, and brick, and on those buildings the roof, the flashing, and the masonry have to be treated as one system rather than three. We inspect Ellicott City houses for free and tell you plainly what the structure needs.
The 2016 and 2018 floods hit Ellicott City hard. Does that affect roofs on the hills?
It does, because the same weather that flooded Main Street lands on every roof in Ellicott City. The 2016 storm dropped 6 inches of rain in two hours and 2018 brought over eight inches in two hours. Roofs on the seven hills above the valley get that volume all at once, and any weak flashing or worn valley shows up immediately.
Do you handle hail and wind damage insurance claims in Ellicott City?
Yes. We write Ellicott City claim scopes in Xactimate, the platform the carriers use. The inspection is free and carries no obligation, whether the damage turns out to be a claim or a retail job.
How long does a roof replacement take on an Ellicott City house?
Most residential replacements in Ellicott City are done in one day. We use Owens Corning shingles, and a full roof replacement includes 100 feet of gutter, gutter guard, and downspouts. We replace siding as well, which is worth doing at the same time if the trim and flashing are already open.
