Don't Hire the Roofman Ever!
As did Laurie below we had exactly the same track record with our flat root - the last time they came out they really messed up by putting cement on the flat membrane in a corner to prevent it from leaking through the Window! We also had them shingle our house and you can see from the street the mess that was made of that! the shingles began buckling immediately and again they came out numerous times to repair the jobThey blamed the shingles and we sent them away - the shingle company said the roofing company didn't not apply them properly and the story continues - I have pictures and papers to prove all of this, but I finally gave up and had an excellent roofer redo the roof job - I can't afford the shingles yet!
