Included on a Full Replacement
100 Feet of Gutter With Your Roof Replacement
Every full roof replacement we do across Central Maryland comes with 100 feet of gutter, gutter guard and downspouts on the same job. It is part of the replacement rather than a second trip and a second invoice, and it is the reason the water coming off a new roof goes where it should.
Included with a full roof replacement. It is not a standalone service, and there is no end date on it.

Why Homeowners Choose Diakite Roofing & Restoration for Roof Replacement
Off and On in One Day
Most residential replacements are torn off, decked, and re-shingled the same day, so your house is not sitting open overnight under a tarp.
100 Feet of Gutter Included
A full roof replacement comes with 100 feet of gutter, gutter guard, and downspouts. New water off a new roof, handled on the same job.
The Deck Gets Checked, Not Covered Up
Once the old shingles are off we walk the sheathing and show you any soft or rotted panels before a single new course goes down.
Watch For These
Signs You Need Roof Replacement
- Shingles curling, cupping, or losing granules across whole slopes
- Bare fiberglass mat showing where the granules washed off
- Shingle tabs and nail pops in the yard after every windy day
- Water stains spreading on upstairs ceilings or on the attic sheathing
- A roof past 20 years old, or a second layer already nailed over the first

- 01
Free Inspection
A HAAG certified inspector walks the roof, photographs every slope, and tells you honestly whether a replacement is warranted yet.

Written Scope and Date
You get the scope in writing with your shingle color and a firm install date. Nothing changes on install day.
- 03
Tear-Off and Deck Check
The old roof comes off to bare wood. Failed sheathing gets replaced, then ice and water barrier goes down at the eaves and valleys.
- 04
New System and Cleanup

Working out how to pay for it? Financing is offered through Enhancify and its lending partners.

Good to Know
Roof Replacement: What Central Maryland Homeowners Should Know
What a Full Roof Replacement Includes on a Columbia Home
A replacement starts with getting the old roof off. Every layer comes down to bare wood, because the deck is the one part of the assembly nobody can grade from a driveway.
With the sheathing open we walk it, mark anything spongy or delaminated, and swap those sheets before new material goes on. Then the sequence runs in order: ice and water membrane at the eaves and up the valleys, drip edge, synthetic underlayment over the field, starter strip along the rakes and eaves, Owens Corning architectural shingles set to the nailing pattern the wrapper calls for, new pipe boots, new valley metal, and step flashing woven into the courses at every wall and chimney rather than smeared over with sealant.

Ventilation gets sized at the same time, not left the way the last crew found it. A roof needs intake low and exhaust high in a rough balance, and plenty of Maryland attics are running exhaust with almost no soffit intake feeding it.
That imbalance cooks shingles from underneath through a humid Howard County July and pushes moisture into the sheathing all winter. Correcting it while the deck is open costs a fraction of what it costs later.

This company was very professional and very prompt. They explained everything to me in detail, along with pictures and videos. They got the job done quickly and thoroughly, and at a reasonable price. I would highly recommend Diakite Roofing and Restoration, and I would use them again if I needed to in the future.
Most Homes Are Done in One Day, and That Is a Weather Decision
Most residential roof replacements we do are finished in one day. That has less to do with hustle than with exposure. A torn-off roof is an open building, and central Maryland weather can turn a clear morning into a thunderstorm by three in the afternoon.
Getting from bare deck back to a dried-in, shingled roof inside one working day is how you keep a pop-up storm from becoming a drywall claim. It takes crew size and staging, which is why we plan the material drop, the dumpster placement, and access before the first shingle moves.
The end of the day matters as much as the start. Debris gets loaded, the ground gets a magnet run for nails, and the driveway and beds get walked before anyone leaves. Homeowners notice that part more than they notice the underlayment.

What Can Change the Scope After Tear-Off
Two things change a roof number after the old material is off, and an honest contractor tells you about both before you sign. The first is layers. One layer coming off is standard; a roof carrying two or three means more labor hours and a heavier dumpster.
The second is decking. Rotted plywood around a chimney, a soft spot under an old skylight curb, or a section of board sheathing that has taken years of slow leaking all has to be replaced, and none of it is reliably visible from the outside.
The other items that sometimes surface: a chimney that needs its counterflashing cut back into the mortar joint instead of caulked to the brick, a skylight old enough that reflashing it makes no sense without replacing the unit, and bath fans discharging into the attic instead of through the roof. We photograph anything like that and show it to you before we touch it.

The Gutter Package on a Full Replacement
Right now a full roof replacement comes with 100 feet of gutter, gutter guard, and downspouts included. It is a package tied to the replacement rather than a separate service we sell, and it exists because new gutter hung at the same time as new drip edge and new starter course is the one moment those three pieces get to line up correctly.
Diakite Roofing & Restoration works Monday through Saturday from 8am to 5pm, and holds a 5.0 rating from 17 Google reviews. Every job starts with a free inspection and no obligation to hire us. Call (667) 200-6656 and we will get you on the schedule.

Before and After
Drag the Slider Across a Roof We Replaced
Both pictures came off our own camera, on the same house and the same chimney, before the tear-off and after the new system went on. Drag the handle, or tab to it and use the arrow keys.
Before and After
One Roof Replacement, Photographed From the Air
The rear corner of the same cottage before the new roof and after it. The red stained deck and its lattice gate, the brick chimney and the concrete slab on the grass are in both frames.
The drone was flown higher for the second frame, so the house sits smaller and the road comes into shot. Side by side rather than a slider, because the two views do not line up closely enough to drag one across the other honestly.

Service Radius
Where We Take Roof Replacement Calls Across Central Maryland
Columbia is the hub every roof replacement crew rolls out of, and the run is the same one the trucks make every morning: US-29, MD-108, MD-100, I-95 and Washington Boulevard. Those corridors are what put Howard, Anne Arundel, Montgomery, Prince George's, Carroll, Frederick & Baltimore Counties inside a working day, on a 35-mile radius out of Columbia.
| Town | County | From Columbia |
|---|---|---|
| Clarksville | Howard County | About 4 miles |
| Ellicott City | Howard County | About 6 miles |
| Laurel | Prince George's County | About 7 miles |
| Silver Spring | Montgomery County | About 16 miles |
| Rockville | Montgomery County | About 17 miles |
| Annapolis | Anne Arundel County | About 25 miles |
Straight-line miles between town centers, measured from geocoded coordinates. They are not drive times and not route mileage. We are a service-area business, so roof replacement happens at your property, not at a counter.
Who We Work With
Roof Replacement in Columbia: Materials, Standards and Permits
- Owens Corning. The architectural shingle we install is Owens Corning TruDefinition Duration, and you pick the color off real samples held against your own brick or siding.

Town by Town
Local Roofing Pages for the Towns We Cover
Housing stock changes fast around here, and so does what fails on a roof. A 1970s Columbia village house with a low-slope porch tie-in is a different job from a brick colonial with three dormers and a cut-up valley, and the storm tracks do not hit every county the same week either. There is a page per town covering the local housing, the weather it takes, and the work we do there.
Howard County. This is home ground. Start with roof replacement in Columbia, roofing in Ellicott City, roof replacement and storm restoration in Clarksville and roofing contractors in Elkridge.

Roof Replacement: Frequently Asked Questions
How long does a roof replacement take on a Howard County home?
Most Columbia homes are one day: tear-off in the morning, new roof on and the site cleaned by evening. Steep roofs and cut-up rooflines can run into a second day, and we tell you which yours is when we quote it.
What shingles do you install on Central Maryland roofs?
Owens Corning architectural shingles. You pick the color off real samples held against your own brick or siding, not off a screen.
What warranty comes with new shingles on a Maryland roof?
Owens Corning warrants the shingles, not us. The Owens Corning Duration shingles we install carry Owens Corning's Limited Lifetime warranty on the shingle materials, for as long as the original owner owns the home, and it transfers to a new owner on Owens Corning's terms. It runs non-prorated for an initial period and prorated after that. It is a manufacturer's warranty on materials and not a warranty from us on the installation, so it does not pay for labor, tear-off or disposal, and it does not cover the parts Owens Corning did not make: flashing, fasteners, pipe boots and wood decking. Owens Corning publishes the terms for each shingle line. Ask for the ones covering the line going on your roof and read them before you sign.
Do I need a permit to replace a roof in Howard County?
Howard County and most of the towns around it require a roofing permit. We handle that paperwork as part of the job and schedule around the inspection.
What comes with a full roof replacement in Central Maryland right now?
100 feet of gutter, gutter guard, and downspouts. That is the current offer, and it goes into the written scope so nobody is arguing about it later.
What if the inspection says my Howard County roof is fine?
Then that is what we tell you, and there is nothing to sign. We would rather be the roofer you call in six years than the one who talked you into a roof you did not need.
