    Bye Bye Roof Leaks

    Bye Bye Roof Leaks
    Flat roof finally failed with age and even a replaced rolled asphalt roof failed to stop rainwater leaking. Replaced the pitch roof too and still it leaked. Finally gave up on roofers and sealed every single new seam plus the new pitch roof where it met the flat roof. Now I'm confident it won't leak. Will probably repeat this after a few months. I did not clean up, but tossed the brush. Also lined my metal watering can and metal bucket to stop those leaking.
