Coping Lifting in Wind
Loose coping on parapet walls rattles and lets water behind the wall flashing. Stains on the inside face of the wall are a common clue.

Hatboro Commercial Roofing Contractor
Edge Metal and Perimeter Flashing Checked Before Any New Membrane
As a Hatboro commercial roofing contractor, we replace storefront and office roofs and decide edge by edge which perimeter metal stays.
Commercial Roofing in Hatboro Starts at the Edge
Older edge metal often decides how Hatboro commercial roofing turns out, so we look at it first.
Owners on older storefronts often ask whether the existing edge metal can stay. It can, only when its attachment, joints, and fit with the new flashing all check out.
Edges that fail those checks come off. Renewing the field while a loose coping or rusted gravel stop stays in place leaves a path for water right beside the new membrane.
- Fasteners and blocking checked under the metal
- Joints between pieces opened and inspected
- Wall flashing matched to the new membrane
- Retained pieces listed in the proposal
Commercial Roofing Problems Along Hatboro Rooflines
Perimeter trouble shows up first on older storefront and office roofs.
Rusted Gravel Stop
Old gravel stop rusts at the joints, opening gaps where the membrane meets the edge. Rust streaks down the fascia show where it started.
Cracked Wall Flashing
Base flashing on brick parapets dries out and splits at inside corners, where the sheet was folded tightest during the last install.
Open Joints Between Edge Pieces
Sealant at edge joints fails, letting water run down the face and into the wall.
Scuppers With Failed Seals
Through-wall scuppers leak where the old sheet was only caulked to the metal.
Wet Insulation Near the Perimeter
Water from failed edges soaks the outer few feet of insulation first.

Commercial Roofing Questions in Hatboro
Answers for Hatboro storefront and office owners.
Can New Roofing in Hatboro Keep the Old Edge Metal?
Only when the old metal is in good shape and fits the new assembly. We check attachment, joints, and compatibility with the new flashing before listing it as retained. Keeping a defective edge while renewing the field leaves a leak path right beside the new roof.
Do You Offer Commercial Roofing for Hatboro Businesses in Older Buildings?
Yes. Storefronts and offices with brick parapets make up much of our Hatboro work, and their edges get the closest look.
Where Can I Find Hatboro Commercial Roofing Near Me?
We serve Hatboro directly. Call with the address, and we will set up a time to walk the roof and check the edges.
Is There a Commercial Roofing Contractor Near Hatboro for Small Roofs?
Small storefront roofs are part of our regular work. The same edge and flashing checks apply whatever the size.
Will New Coping Match the Building?
Coping and edge metal come in many colors and profiles. We pick a profile that fits the wall width and the new membrane.
What Happens to Blocking Under Old Edges?
Rotted or loose wood blocking under the edge metal is replaced, since new metal is only as secure as what it fastens into.
Can a Parapet Wall Leak Without a Roof Leak?
Yes. Cracked coping joints and loose wall flashing let water into the wall itself, so we check parapets along with the membrane.
How Is Retained Edge Metal Tied In?
Retained pieces are cleaned, refastened where needed, and stripped into the new membrane with compatible flashing at every joint.
