Glenolden Commercial Roofing Contractor
New Roofs Built to Drain Low Spots Instead of Holding Water
As a Glenolden commercial roofing contractor, we replace flat roofs and correct the low areas and slow drains that wore out the old one.
Commercial Roofing in Glenolden That Fixes Drainage
Water that sits on a roof shortens its life, and Glenolden commercial roofing work is the time to change that.
Replacement jobs here often reveal low spots and blocked runoff that helped ruin the last roof. Laying new membrane over the same layout brings the ponding right back.
We check drain outlets, the shape of the insulation, and the structure around each low area. Corrections can mean tapered board, crickets between drains, or resetting drain bowls lower.
- Drain heights measured against the field
- Ponds mapped after rain
- Tapered board where slope is short
- Structure checked around sagging bays
Commercial Roofing Problems on Glenolden Flat Roofs
Drainage trouble leaves clear marks on a flat roof.
Drains Above the Low Point
Added layers over the years raised drain bowls above the roof around them, so water circles the outlet without reaching it.
Sagging Bays Between Joists
Deflected deck creates bowls that collect water and debris, and the extra weight of ponding pushes the deck down further.
Ice Sheets in Winter
Ponded water freezes into sheets that stress seams and flashing, then melts and refreezes through every thaw.
Wet Board Under Ponds
Constant water finds small openings and soaks the board beneath, which then holds even more water in the next storm.
Overflowing Scuppers
Undersized or clogged scuppers spill water down the wall, staining brick and soaking the base of the parapet.
What Commercial Roofing Changes on Glenolden Buildings
Drainage corrections are built into the new roof from the first layer of board.
- Failure
Standing Water After Every Storm
Ponds wear the surface and grow algae and debris.
What The New Roof DoesTapered insulation and crickets send water to the outlets, so the field dries within a day of a normal storm.
- Failure
Drains Set Too High
Water circles a drain it cannot reach.
What The New Roof DoesDrain bowls are reset or sumped so the low point sits at the outlet, and new clamping rings hold the membrane tight around each one.
- Failure
Scuppers That Back Up
Clogged scuppers spill over the wall face.
What The New Roof DoesScuppers are resized or reflashed so runoff leaves the roof cleanly.
- Failure
Sagging Deck Bays
Deflected deck between joists keeps refilling with water.
What The New Roof DoesSoft deck is repaired and taper is added so the bay drains toward an outlet instead of refilling after every rain.

Water Still Standing Two Days After Rain?
Ponding that lasts usually means the slope or drains need correcting. Book an inspection after the next storm and we will map where it collects.

Commercial Roofing Questions From Glenolden Owners
Answers about drainage and replacement in Glenolden.
Could a Glenolden Replacement Roof Need Drainage Changes?
It can, where low areas or blocked runoff helped damage the old roof. We check outlets, insulation shape, and the structure around low spots before deciding on corrections. A new membrane over the same layout leaves the water problem in place.
Is There a Commercial Roofing Contractor Near Glenolden for Flat Roofs?
Yes. Flat commercial roofs are most of our Glenolden work, and drainage gets checked on every one.
Does Tapered Insulation Raise Glenolden Commercial Roofing Cost?
It adds material, and the taper plan shows how much. Many owners weigh that against the repeat repairs ponding causes.
Do You Handle Commercial Roofing for Glenolden Businesses With Small Roofs?
Yes. Small shop and office roofs get the same drain and slope review as large ones.
Can Drains Be Moved During a Reroof?
Sometimes. Adding or relocating a drain involves plumbing below the deck, so it is planned with the building owner and a plumber.
What Is a Cricket on a Flat Roof?
A cricket is a small built-up slope, usually tapered insulation, placed between drains or behind curbs so water moves around obstacles toward the outlets.
Will Ponding Stop Completely?
The taper plan is designed to move water to the drains. We check runoff after the new roof is installed and adjust drain flashing where water still collects.
Does Ice Damage Ponded Roofs?
Ponded water that freezes stresses seams and flashing each winter, which is one reason slope corrections are worth planning during replacement.
