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.
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.

Look at the photos
You go through the same photos the inspector took before anyone talks about scope, so you know whether you are buying a roof or keeping the one you have.
- 03
Written scope and a firm date
Retail or insurance, the scope goes in writing with your shingle color and an install date. Permits are handled as part of the job.

Lassana came out and looked at my roof after all the crazy storms going around and told me that my roof doesn't have any damages yet whereas all the over roofers told me I need a new roof. My Roof was only 10 year old

Who You Are Calling
The roof and the claim, handled by the person who inspected it
Who actually shows up
Diakite Roofing & Restoration works out of Columbia and covers Howard, Anne Arundel, Montgomery, Prince George's, Carroll, Frederick & Baltimore Counties, roughly a 35-mile ring. Lassana Diakite owns it and does the inspections himself.
He is HAAG certified, which matters most once hail is in the picture, because that inspection has to hold up in front of an adjuster and not just look thorough from the driveway. Scopes get written in Xactimate, the same estimating software the carriers price from, so the paperwork lines up instead of turning into a three-week argument.

What happens when the roof turns out fine
The reason to call a smaller outfit is what happens when the roof turns out to be fine. One homeowner had roofer after roofer telling him he needed a replacement on a ten-year-old roof. Lassana went up, found no damage, and said so.
That review is still sitting on the Google profile. Nothing gets sold here that the shingles do not need, and the inspection costs the same either way, which is nothing.
What a replacement day looks like
When a roof does have to come off, most residential replacements are torn off, decked and re-shingled inside one day, so the house is not sitting open under a tarp overnight. Owens Corning architectural shingles go on over a deck that has been walked and checked, and any soft sheathing gets shown to you before new material covers it up.
A full replacement also carries 100 feet of gutter with gutter guard and downspouts on the same job rather than a second trip. The Google rating is 5.0 across 23 reviews, every one of them earned on jobs like these.

Built for Our Weather
What Central Maryland storms actually do to a roof
Hail is the one that gets missed
Hail is the one that gets missed. A bruised shingle rarely leaks on the day it is struck. The impact fractures the mat and knocks granules loose, the exposed asphalt then bakes through a couple of humid summers, and the slope starts failing two or three years after the storm that caused it.
By then the claim window is usually closed. That is why the inspection is chalk-marked and photographed slope by slope instead of eyeballed from the driveway, and why a certified read matters more here than a quick look.
Great experience! The contractor did an excellent job installing my siding. They were professional, efficient, and paid close attention to detail. The finished work looks amazing, and I would definitely recommend them to anyone looking for quality siding work.
Wind does its damage at the edges
Rakes, ridges and the first courses above the eaves are where tabs lift and the seal strip lets go, and a lifted tab does not always look wrong from the street. Then there is the freeze-thaw stretch either side of winter, which pushes meltwater back under the first courses at the eave, so ice and water barrier along the eaves and valleys is not an upsell. Neither is balanced intake and ridge ventilation, which is what keeps a humid attic from cooking the underside of a new roof before it has earned its keep.

Good to Know
Frequently asked questions
Do you charge for the inspection?
No. The inspection is free and there is no obligation attached to it. A HAAG certified inspector walks the roof, photographs every slope, and tells you what is actually up there before anyone talks about scope or price.
What areas do you serve?
We work across Howard, Anne Arundel, Montgomery, Prince George's, Carroll, Frederick & Baltimore Counties from Columbia, roughly a 35-mile radius. That includes Columbia, Ellicott City, Clarksville, Elkridge, Laurel, Silver Spring, Rockville, Bowie, Glen Burnie, Annapolis, Eldersburg, Catonsville, plus the towns in between.
How long does a roof replacement take?
Most residential replacements are one day: tear-off in the morning, the new system on and the site cleaned by evening. Steep or cut-up rooflines can run into a second day, and we tell you which yours is when we scope it.
Do you handle insurance work?
Yes, that is where the restoration side comes from. We document the damage slope by slope, and the scope is written in Xactimate, the same estimating software the carriers use, so the numbers line up with what your adjuster is looking at.
Who actually shows up?
Lassana Diakite. He owns the company and does the inspections himself, so the person on the roof is the person you spoke to on the phone.
What shingles do you install?
Owens Corning architectural shingles. You pick the color off real samples held against your own brick or siding rather than off a screen.
