The flat parts are the rear addition, a porch enclosed years ago, or a dead-flat section over the kitchen of a Victorian built back when the borough made organs. Water sits on those roofs, and the seams often fail before the pitched roof shows any wear.

Other Work We Do in Washington
Where to Find Flat Roofs on a Washington House
Washington grew in the late 1800s and early 1900s as a center for making musical instruments, organs above all, and many of the borough's Victorian houses went up then. More houses and apartment buildings followed after World War II.
The flat roofing on these homes is rarely visible from the street. It is on a rear addition or an upstairs porch that was roofed and turned into a room. It is usually EPDM rubber or torch-down with a patch or two already on it, often caulk.

When a Flat Roof Starts Showing Its Age
A flat roof tends to show problems before water comes through. Look for puddles 2 days after rain, lifting seam edges, spots that give when you step on them, a stain spreading under the flattest part, or coating that peels over and over. One of those is enough reason to call before winter.
Flat Roofing Differs From Shingle Work
Flat roofing is a trade of its own, and a patch made with the wrong material or detailing tends to leak again within a season.
The Membranes We Repair
On older flat roofs, modified bitumen torch-down is common. Black EPDM rubber is the other common one, and with maintained seams and flashings it lasts decades. It usually fails at the joints.
On newer work you may find white TPO, which has to be heat-welded to repair.
What Actually Wears a Flat Roof Out
Leaves block drains and scuppers. Winter freezes open small seam gaps a little more each time. People on the roof, cable and satellite installers especially, also cause punctures.
What Sets the Number on a Flat Roof
The kind of membrane decides a lot, because EPDM, torch-down and TPO each need a different repair method. Fixing one seam on a healthy membrane is a small job. When it is more than that, we make the call with you over the photos.
Warranty on Repairs and Replacements
Roof repairs carry a 2-year warranty; roof replacement carries a 50-year warranty. We hold NJ Home Improvement Contractor registration #13VH11720500 and carry insurance. Whoever priced your Washington job also does the work.
Patch, Coat, or Re-Cover: The Math
If a sound EPDM or TPO membrane has a bad seam, repair the seam, which costs little. An aging roof that is still dry can take a silicone or acrylic coating, close to 10 more years for a small part of what tear-off costs.
A roof brittle from edge to edge should be re-covered. One that is wet underneath should be replaced, since coating traps the water and the deck rots. We will not coat a wet roof.
The inspection shows which case you are in, and a moisture scan sometimes decides it.
The Pitched-to-Flat Transition, Done Right
On Washington's older houses the leak is most often where the steep original roof runs down onto a flat addition. That joint was often flashed with spare material when the addition was built, and it takes all the water from the roof above.
We rebuild it as one continuous detail, tying the pitched flashing into the membrane. Since we do both pitched and flat roofing, we follow the water from the top down. On open lots near the edge of the borough we also fasten and seal the edge metal between the two roofs against wind.
