Roof Replacement in Baltimore County: What to Expect

From the free inspection to the final walkthrough, here's how a roof replacement in Baltimore County works, and what to ask any roofing contractor before you sign.

It starts with a free roof inspection

A good roof replacement in Baltimore County starts on the roof, not on the phone. We check the shingles, flashing, ventilation, gutters and, from the attic, the decking, then give you a written estimate with photos of what we found.

Sometimes the answer is a repair, not a new roof. If that's the case, we'll tell you.

Tear-off and decking

Many Baltimore County homes were built from the 1950s through the 1980s, and some have been re-roofed more than once. Once the old roof comes off, we can see the decking, the wood the shingles are nailed to, and replace any boards that are soft or rotted.

Ask any roofing contractor in Baltimore County how they price decking repairs before the job starts, so there are no surprises.

What goes on a new roof

A new shingle roof is a system: synthetic underlayment over the whole deck, ice and water shield at the eaves and valleys, new flashing at walls and chimneys, ridge ventilation and the shingles themselves. We install Atlas Pinnacle Pristine shingles.

Northern Baltimore County gets more snow and ice than the communities near the water, which makes ice and water shield and good ventilation especially important there.

Flat roofs on Baltimore rowhomes

Rowhomes in Dundalk, Essex, Towson and Baltimore City often have flat or low-slope roofs in back. Those get a different system, a modified bitumen or single-ply membrane, with drainage planned so water doesn't sit.

How to choose a roofing contractor in Baltimore County

Check that the contractor holds a Maryland Home Improvement Commission (MHIC) license. You can look up any license number on the Maryland Department of Labor website. Ours is MHIC# 142024.

Ask for a written estimate, photos of the problems they found, and the warranty in writing: both the manufacturer's warranty on the materials and the contractor's warranty on the labor.
