Rowhouse and Twin Roofs in Upper Darby Township, PA
Upper Darby Township lies about 7 miles west of Center City in Delaware County, right against West Philadelphia. The Census counted 85,681 residents in 2020 and estimates 85,458 for 2025, the most of any township on this site. The median owner-occupied home is valued at $219,100, and owners occupy 57.5% of homes.
It is its own municipality with its own permit office, separate from Darby Borough and Darby Township. Its motto is "The World in One Place", and more than 100 languages are spoken here. On most blocks the question is practical: patch, recoat or replace a low-slope rear roof that meets the neighbor's at a shared wall.
Rows, Twins and Flat Rear Roofs
The township takes in Drexel Hill, Highland Park, Bywood and Llanerch, plus the 69th Street area. Many homes are brick rowhouses and twins with a low-slope roof draining toward the back. On those roofs, these signs usually start the conversation.
- Water that sits. Puddles that linger days after rain mean poor drainage.
- Blisters and open seams. Bubbles in modified bitumen or lifted laps in EPDM let water creep underneath.
- Worn-through coating. Once the silver or white coat chalks away, sunlight ages the membrane faster.
- Stains along the shared wall. Leaks near the party wall often trace to flashing, not the middle of the roof.
Services for Upper Darby Township, PA Roofs
- Full replacement. Old membrane layers come off, the deck boards get checked, and new modified bitumen, EPDM or TPO goes down. See full roof replacement.
- Storm damage. Wind can peel a loose membrane edge. A roofer can photograph and price the fix; the claim stays yours. See storm damage roofs.
- Metal roofs. Many porches and bays have small painted metal roofs that rust with age. See metal roof replacement.
- Shingle roofs. Detached homes and pitched fronts often carry asphalt shingles. See shingle roof replacement.
- Repairs. A split seam or worn party-wall flashing can often be fixed alone. Ask whether the membrane underneath is sound. See roof repair.
Weather That Wears on Low-Slope Roofs
Flat roofs usually wear out slowly: standing water, freeze-thaw cycles and summer heat on a dark membrane can each shorten their life.
The bigger events were regional. The National Weather Service recorded a 68 mph gust at Philadelphia International Airport and 71 mph in Holmesburg during the derecho of June 3, 2020. Delaware County was in the 2021 federal declaration after Ida's remnants, a past record and not help offered now.
The February 22–23, 2026 blizzard brought a disaster emergency across the line in Philadelphia; heavy, wet snow and strong wind were in the forecast. Melting snow pools on a flat roof, so clear the rear gutter afterward.
Two Credentials and a Township Permit
Upper Darby Township lists roofing permits in its own fee ordinance, and its Department of Licenses & Inspections handles them (610-734-7613). Philadelphia's L&I and Darby Borough don't issue permits here.
For residential work the township expects a township contractor license plus the Pennsylvania Home Improvement Contractor registration with the Attorney General. The state registration alone doesn't satisfy the township. Check the state record online, ask to see the township license, and agree in writing on who applies for the permit.

Built With Upper Darby Township, PA in Mind
Row and twin owners share more than a wall, since water from a failing roof next door can run along the joint. Ask a roofer these questions.
- Which membrane, and how many plies? Ask for modified bitumen, EPDM or TPO to be named in the contract.
- Is a coating in the price? Ask whether a reflective coat is included.
- What happens at the party wall? Ask how the flashing ties in on your side.
- Is the rear gutter included? Every drop leaves these roofs by that gutter.
- How is payment split? Nothing is owed before signing, a deposit on a contract over $5,000 is capped at one-third, and you have three business days to cancel.

Upper Darby Township, PA Questions, Answered
Is recoating my flat roof the same as replacing it?
No. A coat only protects a membrane that is still sound. It won't cure a membrane that is cracked, soaked or splitting at the seams. Have the roofer cut a small test spot or check the layers underneath before you pay for a coat.
Is a state registration enough for a roofer working in Upper Darby Township, PA?
Not by itself. The township asks residential contractors for its own contractor license on top of the Pennsylvania Home Improvement Contractor registration. Ask for both, look up the state record on the Attorney General's website, and keep copies with your contract.
My neighbor's half of the twin needs a roof too. Can both be done together?
Often that is the cleaner job, since the shared-wall flashing gets done once. Each owner should still sign a separate written contract with its own price, deposit and cancel notice, and the roofer should explain who files the permit for each house.
Do I pay anything to send a request?
No. The roofing company that receives your request pays this site a referral fee; you pay the site nothing and get nothing from it. Any price for roof work is agreed between you and the roofer, in writing, before work starts.
