Roofers in Lawrenceville, Pittsburgh
Lawrenceville rowhouses often have a small sloped front roof and a low-slope rear section, sharing walls with the neighbors on both sides. From Lower Lawrenceville through the Arsenal area, that combination calls for a different kind of roofing job.
Party walls and rear roofs
When two rowhouses share a wall, the flashing along that wall is often the weak point. Water that gets in there can show up in your bedroom or your neighbor's. Old coatings over tar are common on rear roofs, and they hide wet layers underneath.
If your rear roof holds puddles, a new EPDM roof with a better slope to the gutter is usually the lasting fix. Have a look at our flat roof repair page for how that works.

Questions for roofers in Lawrenceville
What do roofers charge for a rowhouse roof in Lawrenceville?
Small repairs usually run $350 to $1,500. A new rubber rear roof is usually $9 to $15 per square foot, and many Lawrenceville rear roofs are small, so the total stays modest.
Who pays for roof in townhouse?
In a typical Lawrenceville fee-simple rowhouse, each owner handles their own roof, and shared walls need a conversation. If you belong to an association, check its documents.
Can you put a rubber roof over an old tar roof in Lawrenceville?
Not straight onto it. EPDM makers such as Mule-Hide say asphalt products aren't compatible with rubber, so the old tar has to come off or be covered with a separation board. Pennsylvania's code, as of 2026, also bars covering a roof that is wet or already has two layers, and coated Lawrenceville rear roofs often hide wet layers.
How high should flashing be on a Lawrenceville party wall?
Where a rear roof meets a party wall or parapet, EPDM makers such as Mule-Hide call for the membrane to run at least 8 inches up the wall where possible, or above expected snow and water levels. The top edge is then fastened with a termination bar and sealed.
