Roofing for Lawrenceville rowhouses and brick homes
Lawrenceville is lined with brick rowhouses and narrow homes set close together along the Allegheny River. Straight A Exterior Renovations provides roof repair, roof replacement and flat roofing for Lawrenceville homeowners, including the low-slope rear roofs that are so common here.
Many of these homes have two very different roofs. The front may be pitched and shingled. The back, often over a kitchen or rear addition, is low-slope or nearly flat. The two need different materials, and the joint where they meet, along with the shared walls on either side, needs careful flashing.
Whether you just bought a rowhouse or have lived in one for years, we start with a free inspection and a written quote you can actually read.
Local know-how
What makes Lawrenceville roofs different
Rowhouse roofing is its own skill. Shared walls, tight lots and low-slope sections all change how a roof is built and how it fails.
Narrow streets and limited parking also shape the job. Planning where material goes and how debris comes off is part of the work.
Low-slope rear roofs
Rear roofs on rowhouses are often too shallow for shingles. They need a rubber membrane designed for low slopes, or they will pond water and leak.
Shared walls and parapets
Where your roof meets your neighbor's wall or a parapet, the flashing has to tie in cleanly. This is a frequent source of leaks in attached homes.
Narrow streets, no driveways
Most homes have no driveway and little room out front. We plan deliveries and debris removal around street parking and tight access.
Renovated homes with mixed roofs
Many Lawrenceville homes have been updated over time. Additions and rear decks can leave a patchwork of roof sections that need to work together.

Our process
How we work on a Lawrenceville rowhouse
On narrow Lawrenceville streets, we time deliveries and debris removal to keep the sidewalk passable and the work area tight.
- Step 1
Free inspection
We check the front roof, the low-slope rear roof and every joint with a shared wall or parapet, and take photos of each.
- Step 2
Itemized written quote
Front and rear roofs are quoted separately, with rubber roofing for sections too shallow for shingles, and the plan for access is spelled out.
- Step 3
Storm claim help, when needed
If a storm damaged the roof, we document it, help you report it and work with your insurance company and adjuster through the claim.
- Step 4
Installation
We protect the adjoining roof, install the right material on each section and tie the new roof cleanly into shared walls.
- Step 5
Cleanup and walkthrough
Debris comes off the roof and off the sidewalk, every nail is picked up, and we walk the property with you at the end.
- Step 6
Warranty begins
From the day the job is finished, the roofing materials on your front and rear roofs carry a lifetime product warranty, and Straight A backs the installation with its 2-year workmanship guarantee.
FAQ
Questions from Lawrenceville homeowners
Why does my flat rear roof keep leaking?
Low-slope roofs leak when water ponds, when seams or patches fail, or when the flashing at a wall or skylight gives out. Shingles on a very low slope are another common cause. We find the specific reason and quote the right fix.
Can you replace only the back roof on my rowhouse?
Yes. The rear and front roofs often age differently. We can replace the low-slope section alone and tie it into the existing front roof properly.
Will working on my roof affect my neighbor's roof?
On attached homes, the roofs meet at the shared wall. We protect the adjoining roof and flash the joint so water stays out of both homes. We are happy to explain the plan to your neighbor too.
There is no driveway. Where does the material and dumpster go?
We plan that during the estimate. Depending on the street, that may mean timed deliveries, a smaller debris setup or carrying debris to a truck. The plan is part of your quote.
What material do you use on a low-slope roof?
We install rubber roofing on flat and low-slope sections. It is made to handle slow drainage that would cause shingles to leak.
