"I would like to ask your thoughts on the "pros and cons" on the use of the self-adhesive, 3 ft wide membrane (ice dam) used on the edge of the roof line. I believe that this would replace the felt paper, under the 1st rows of asphalt shingle. We have a sloped roof, but I do not know how ste...

One of the most successful, but most expensive ways to keep leaves out of rain gutters is to place a solid shield over the top.
Using the principle of surface tension of water, the water flows over the shield and wraps around its outside curve. That curve extends out over the rain gutter itsel...
One of our callers had one missing roof shingle. How to replace it?
Working on a warm day, lift the shingle above to expose the nails. Remove the nail, or cut out around the nail to release the damaged shingle. Pound the nail in flush or pull it out. Getting rid of this nail is probably the h...
