Ask This Old House Season 10 Episode 13 Ice Dams, City Trees

In the season 10 episode 13 of Ask This Old House, titled "Ice Dams, City Trees," the team tackles two common winter issues - ice dams and urban trees.

First, host Kevin O'Connor visits a home in upstate New York where the homeowner has been experiencing ice dams on their roof. Tom Silva, the show's general contractor, explains what causes ice dams and the correct way to prevent them. He shows how to install ice and water shield, proper ventilation, and insulation to avoid the buildup of ice.

Next, landscape contractor Roger Cook travels to Cambridge, Massachusetts, to help a homeowner whose tree's roots are growing into the city's gas line. Roger works with a specialist to determine the best way to remove the roots without damaging the tree or the gas line.

Back in upstate New York, plumbing and heating expert Richard Trethewey is called to fix a master bathroom shower that has been installed incorrectly, causing leaks and mold. Richard gets to work demonstrating how to properly secure the shower pan, apply waterproofing materials, and re-tile the shower.

Finally, Kevin joins Roger to tour a winter garden in Cambridge that showcases a variety of plants that thrive in cold weather. Roger highlights the different types of coverings, fertilizers, and layouts that can be used to help extend the growing season.

Overall, "Ice Dams, City Trees" offers practical solutions to some of the common issues homeowners may face during the winter season.
