Sorted by rating and then by review count, Westview Roofing Co comes out first, and Diakite Roofing & Restoration, which wrote this page, comes out fourth.

How we built the list
The search was "roof replacement" with the location set to Ellicott City, Maryland, pulled through DataForSEO's Google Maps endpoint at 02:44 UTC on October 24, 2026, which was late on the evening of October 23 here. Twenty listings came back. We dropped a painter and one listing Google filed under siding contractor, which left 18 roofing contractors, every one of them rated.
The sort is two numbers, star rating first and then the count of Google reviews behind it. Rating first is a blunt rule. It puts a 5.0 from 11 reviews ahead of a 4.9 from 223, and you may weigh that the other way, so the other eleven are listed below with their numbers. Google's own order was different again: it put Semper Roofing Ellicott City first and us sixth, and it doesn't publish how much distance counts.

What you get if you call us
The owner climbs the roof himself on the free inspection and photographs every slope, the ridge and hips, the valleys, the flashing at each chimney, dormer and wall, the pipe boots and the metal at the roof edge. You get those photos and a written scope, and you decide from them whether the roof needs replacing at all.
If it does, we strip to bare wood and check every board, replace the bad ones, then lay ice and water membrane at the eaves and valleys and synthetic underlayment over the rest. Step flashing gets woven into the shingle courses at chimneys and walls instead of being smeared with sealant. Ellicott City has taken 6 inches of rain in two hours, and later more than 8 inches in two hours, so valley metal on a house there gets sized and lapped for the water two roof planes dump into one channel. Most homes are torn off, re-roofed and cleaned up in one working day, and a full roof replacement includes 100 feet of gutter, gutter guard and downspouts.
One review from Glen Burnie, as David G left it on Google: "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."
What a star rating leaves out
A rating is what past customers thought of the job. It won't show you who comes out to inspect the roof, or what happens to the deck once the old shingles are off. Our guide on how to choose a roofing contractor in Maryland goes through the checks we'd make on anyone on this page, us included.
Our free inspection carries no obligation, and we work Monday through Saturday, 8am to 5pm. Call (667) 200-6656 or book through the contact page.
