Roof repair and replacement
Leaks, missing shingles, slate, copper, cedar shake and metal. Most roofs need a repair, not a new roof. When a roof is worn out end to end, we replace it, and I show you the pictures of why.

All our services
What do you fix on the outside of a house?
Roofs first, and everything else that keeps water out of the house. The numbers match the drawing above.
Skylights
Most skylight leaks are the flashing around it, not the glass. We reflash it so the water goes around the skylight instead of under it.
Flashing and vent pipes
Flashing at walls, valleys and vents is the leak I find most. A cracked rubber boot around a vent pipe gets replaced, and a new boot lasts with maintenance.
A new copper vent pipe collar we installed on a slate roof, and new copper transition metal where we reinstalled another installer's synthetic slates.
Chimneys
Crowns, caps, flashing, repointing and rebuilds above the roofline. We work on the outside of the chimney. For liners and cleaning inside it, call a chimney sweep.
Chimney crowns Chimney caps Chimney flashing Chimney leaks in rain
Gutters
We clean, repair and install gutters, fix leaking joints and loose hangers, and add or extend drip edge so water drops into the gutter, not behind it. Most homes don't need gutter guards. We install them if you want them, or where trees drop large fruit or flowers that can clog a downspout. We also clean or remove guards you already have.
Drip edge face-nailed by another installer. That's not how it should be done, and we fix it when we see it.
Gutter services Overflowing gutters Gutter pulling away Water behind gutters
Soffit and fascia
When a gutter overflows for a while, the wood behind it rots. We replace the rotted fascia and soffit and fix what made it rot.
Downspouts, drains and window wells
We fix loose downspouts and tie them into underground drains. We flush downspouts when you ask or when we suspect a clog, and we clear window wells so water stays out of the basement.
Flat and porch roofs
Modified bitumen and rubber flat roofs on rowhouses and porches. We repair seams and edges, and a fresh silver coat about every 5 years keeps a flat roof going.
Siding and trim
We repair and replace siding and trim so the weather stays out and the outside of the house looks taken care of again.
Siding boards we replaced, primed and ready for paint.
Exterior caulking
Open joints around windows, doors and trim let water into the wall. We clean out the old caulk and seal them again.
Porches and decks
Worn porch floors, soft boards and deck stairs. We replace what's rotted and match the rest as closely as we can.
Steps, walks and small concrete
Brick steps need a footer under them to stay put, so that's where we start. If you'd rather have concrete and your neighborhood allows it, we can replace brick steps with concrete. We also replace sunken sidewalk slabs.
Brick, stone and mailboxes
Repointing brick and stone walls, and rebuilding brick pillars and mailboxes. We match the brick and mortar to the house as closely as we can.
Roofs too steep to walk
We get up on the roof whenever it's safe. If a roof is too steep, too high or too fragile to walk, I fly the drone so we can still see it up close. I'm an FAA-licensed drone pilot.

Exterior work only. We don't do interior work. If water got inside, we fix where it's getting in. Leaking right now? Here's what to do first, and when it's safe to get up there, we can sometimes put a temporary cover on until the roof is dry enough to repair.
Built for Baltimore houses
What does Omni-Roof do?
Omni-Roof fixes the things that keep a Baltimore house dry: roofs, gutters, chimneys and brick, and porches and steps.
I'm James Preston, the owner. I've worked on city rowhouses and county homes for 24+ years, thousands of them, and we still work the same way. We find the leak, I give you a written price before we start, and we fix it if a repair will hold.
A lot of “roof leaks” in Baltimore turn out to be a downspout, a chimney crown, or one bad flashing joint. So on site we check the roof, flashing, gutters and chimney together. Licensed and insured, MHIC #154344, and BBB accredited, A+.
City rowhouses
A lot of our work is on rowhouses in places like Canton and Fells Point. The flashing and chimneys on shared walls take a beating, and flat roof seams start leaking after a wet week.
County homes
Out in the county, we fix shingle and slate roofs in Towson, Perry Hall and White Marsh after high wind, plus the gutters and fascia that go with them.
Everywhere
Flat porch roofs that start leaking where they meet the gutter. That's most of what we do, in the city and the county.

I would like to thank James Preston of Omni Roof for the work he performed fixing the soffit on my roof. The fast response to my request and the speed to complete the fix was outstanding. Omni Roof will definitely be my go-to choice for future work needed.
Great work. Always on time and very professional. I recommend this business to everyone! 2 thumbs up.

What services do you offer?
Mostly roof repairs, including flat roofs, and roof replacement when a roof is worn out. We also do chimney and brick masonry, gutter cleaning, repair and installation, siding, porch and deck repairs, and small concrete jobs like porch steps. It's all on the outside of the house. We don't do interior work.
How do you make sure the work is done right?
We find the real source of the problem before we fix anything, we take pictures before and after, and every job gets done the way I'd want it done on my own house. I have 24+ years on thousands of Baltimore-area homes.
How does a job usually go?
It starts with a text or a call and a look at the problem. We get up on the roof whenever it's safe. Then I give you a written price and a rough idea of timing. While we're working, we keep you in the loop until the job is finished.
How can I get a price?
Text your address and a few pictures to 443-900-4815, call, or use the form on the website. We'll set up a time to come look. You get a written price before work starts, except small fixes you OK on the spot, which we can do while we're there.
Do I need gutter guards?
Most homes don't need them. We install guards if you want them, or where trees drop large fruit or flowers that can clog a downspout. We can also clean or remove guards you already have.
Do you work on the inside of chimneys?
No. We work on the outside of the chimney: the crown, cap, flashing, brick and mortar, and rebuilds above the roofline. For liners and cleaning inside the chimney, call a chimney sweep.
Can you replace brick steps with concrete?
Yes, if you want concrete and your neighborhood has no restrictions on it. If you're keeping brick, brick steps need a solid footer under them, so we check that first.
