An addition was attached to my house 16 years ago. It is a low pitch and was attached around a chimney. The roof has been replaced twice due to leaking. This roofer will not respond.I believe it is where the addition meets the original that was not flashed correctly. I also suspect I need a cricket around the chimney and new chimney flashing. Yesterday the water started seeping down the wall. Local roofers are swamped and "put me on the list". Any good homeowner reference material to guide me through or should I tarp it and wait for a pro? Thanks.

Hello. As you point out, the leaks are most likely coming from two places: 1 - the join between the addition and the original roof structure, and 2 - the chimney area. Our rule is that chimneys over 18" in width must be cricketed (the industry consensus is between 18" - 24"). Additionally, the proper installation of a chimney flashing involves the use of a reglet which requires grinding into the chimney brick to a depth of 1" so that the flashing is actually fixed inside the brick (rather than simply being tarred and tacked to the oustide).

You mention that the addition has a low slope. The roofing material used should take this into account. It is difficult to comment without knowing the precise slope, however if you have a 1:12 - 3:12 pitch, be wary of installing shingles as snow & ice can back-up quite easily.

Please feel to contact me if you would like additional advice or information. I will try to point you in the right direction for your geographic location.

what is the pitch and what roofing material is used?

Excellence is its own reward!
