1909 brick duplex in Como

The rear roof over the back porches had been patched with tar so many times that water sat in the low spots for days after rain. The owner, who lives in the upper unit, had a leak over the kitchen.

We tore off the old rolled roofing, replaced two sheets of soaked decking and added tapered insulation to move the water toward a new scupper. The EPDM is fully adhered and turns up the brick parapet under a termination bar.

The main roof is shingles in good shape, so we left it alone.
