Is Water Collecting Where Your Metal And Flat Roofs Meet?
Greendale commercial roof repair on mixed buildings focuses on the joint where a metal roof meets a flat roof, plus the seams and screws on both sides.

- Transition flashing rebuilt
- Metal screws and laps
- Flat roof seams
Greendale Commercial Roof Repair Where Two Roofs Meet
Greendale commercial roof repair on buildings with a metal addition beside an older flat roof starts at the transition between them.
A metal roof sheds water fast and dumps it onto the flat roof below. Where the two meet, the flashing has to bridge ribbed panels and smooth membrane, and it moves differently on each side.
We rebuild that transition with closures fitted to the panel ribs, membrane flashing turned up under the metal, and extra membrane where water lands.
- Rib closures fitted at the joint
- Membrane turned up under the metal
- Landing area reinforced
- Screws and laps checked on the metal side
Commercial Roof Repair Issues On Greendale Mixed Roofs
Buildings with two roof systems leak in places single-system buildings never do.
Runoff
Erosion Where Metal Drains Onto Flat
- You See
- Worn, thin, or blistered membrane right below the metal eave.
- What It Means
- Concentrated runoff wears one strip of membrane. A reinforcing layer and a splash path spread the flow.
Gaps
Missing Rib Closures
- You See
- Birds, debris, or daylight in the open ends of metal ribs.
- What It Means
- Open rib ends let wind push water under the panels. Foam or metal closures fitted to the profile seal them.
Movement
Loose Screws On The Metal Side
- You See
- Backed-out screws and rust rings near the transition.
- What It Means
- The addition flexes at the joint, loosening nearby screws. Upsized screws with new washers grip again.
Volume
Overloaded Flat Roof Drains
- You See
- Water spilling over flashing during storms near the transition.
- What It Means
- Drains sized for the flat roof now take the metal roof runoff too. Cleared drains and taller flashing handle it.
Why Commercial Roof Repair In Greendale Fixes Both Sides
Repairing the transition and both roofs together stops the leak from moving to the next weak point.

Protected Landing

Closed Ribs
Fitted closures keep wind-driven rain and birds out of the panels.
Tight Metal

Both Spaces Dry
The addition and the original building stay dry together.

Greendale Commercial Roof Repair Questions
What owners of mixed metal and flat roofs ask.
- 01
Do you repair metal and flat roofs on Greendale businesses?
Both, and often on the same building. Typical work includes new screws and washers, resealed laps and seams, rebuilt flashing, and cleared drains, with the cause of each leak explained.
- 02
How do I find a commercial roof repair contractor near Greendale?
Look for one who repairs both metal and membrane roofs, so the transition gets fixed by one crew. Ask to see photos of the joint before and after.
- 03
Why does the leak sit right where the two roofs meet?
Metal and membrane expand at different rates, and rigid flashing between them tears. Runoff from the metal roof also lands right at that joint, which wears the membrane there first.
- 04
What does Greendale commercial roof repair cost at a transition?
Price depends on the length of the joint, how much membrane below the eave is worn, and whether wet insulation sits under it. The free roof walk ends with a written price for the transition and each roof.
- 05
Does the flat roof need bigger drains after a metal addition?
Sometimes. When the metal roof sends its runoff to the flat roof, existing drains carry more water. Clearing them, raising flashing, and adding a scupper are the usual fixes before resizing anything.
- 06
Can the transition be fixed without touching the metal roof?
Partly. The membrane side can be rebuilt alone, but rib closures and the flashing turned up under the panels need the lowest metal panels lifted or refastened.
- 07
Is Greendale part of your regular service area?
Greendale is one of the five towns we serve from Richmond, along with Lawrenceburg next door. Buildings there get the same roof walk and written price as any other.
