A silver coat is maintenance for roofing that is still sound, not a repair for a leaking roof.

Where flat roofs leak

Open seams, blisters, and flashing are the places to check before coating a leaking roof.

On a rowhouse, pay attention to where the roof meets a wall or the house next door. Flashing that has pulled away from the wall can let water in behind it.

We look at the whole roof, including the seams, the flashing at the walls and the house next door, and any drains or scuppers.

Repair first, then decide about coating

We repair open seams, blisters, and flashing that need work. Written price before work starts, except small fixes you OK on the spot.

If the roofing is still sound and needs coating, a silver coat is maintenance. It does not seal an open seam or fix flashing that has pulled away from a wall. When the roofing underneath is worn out, coating it will not bring it back.

Read how often a flat roof needs a silver coat for coating maintenance, not a leak repair.

What kind of roof is under the coating?

Most Baltimore rowhouse flat roofs are modified bitumen, a rolled asphalt roofing. Some older ones are built-up roofing, and some newer ones are rubber.

The repair question comes first: where is water getting in, and is the rest of the roofing still sound?

If water is coming in now

Stay off the roof. Take pictures of what you can see safely from the ground and of any dripping or stains inside. Text the pictures and your address.

Flat roof repair questions

What usually causes a flat roof leak in Baltimore?

Open seams, blisters, and flashing are common leak spots. On rowhouses, flashing where the roof meets a wall or the house next door needs attention.

Can a silver coat fix a leaking flat roof?

No. A silver coat is maintenance for roofing that is still sound. Open seams, blisters, and flashing need repair before coating.

Does a leaking flat roof always need replacing?

Not always. The first question is where water is getting in and whether the rest of the roofing is still sound. When the roofing underneath is worn out, a coating will not bring it back.

What should I send James about a flat roof leak?

Stay off the roof. Send pictures taken safely from the ground, pictures of any dripping or stains inside, and your address. Say when the leak shows up.
