I had a few roofers and contractors in to discuss how to fix the problem.  They all agreed that we needed a new roof (you can tell from the photo above).  They differed on how to fix the problem. 

One contractor suggested using GAF Liberty roofing.  It’s an asphalt mix made especially for low sloping roofs.  In the end I decided our roof was too flat for this option.

Another contractor recommended a rubber roofing the comes in 4 feet wide rolls.  Some varieties of this needs to be torched to seal the seams.  I didn’t want a torch to be used on our roof and was worried about all of those seams leaking in the future.

The last contractor recommended using a large rubber sheet to put on the roof.  This made the most sense to me in terms of staving off future leaks.  Also, that contractor installed the same material on the flat roof on his daughter’s house (she’s our neighbor).  That’s a good recommendation for me!  This rubber has only a couple of seams with a cement adhesive.

There is another area on the house that has a low slope (but not as flat).  This roof you can see from the ground, so they put the Liberty roofing there and matched the color to the regular roof. 

You can see in the image above how the Liberty roof in the foreground matches the regular roof in the background.

Talk to a few roofers to see what they recommend for your roof.  Often you get a better idea which is the best choice for you after you hear all the options.
