Just like when you’re shingling a roof, you can install felt underlayment under a metal roof, but a synthetic underlayment like adhered ice and water shield is the best option. These use adhesives rather than mechanical fasteners, so you have fewer penetrations going through your roof deck and a lower risk of leaks. Ice and water shield is also easier to install because you don’t need additional tools or fasteners to attach it to the roof deck.

Metal roofs do not inherently leak more than shingle roofs; when properly installed, they are generally less likely to leak. Asphalt shingle roofs are more susceptible to leaks due to factors like wind uplift, damage from extreme weather, moss growth, and ice dams. Over time, asphalt shingles also lose their protective grit, which reduces their waterproofing capabilities. In contrast, metal is a more resilient material that stands up better to heavy precipitation and high winds. However, metal roofs can develop leaks if they are poorly installed, have improperly sealed fasteners, or experience issues from thermal expansion. For this reason, professional installation and regular maintenance are crucial to ensure a metal roof's longevity and superior protection against leaks.

Underlayment exists under your tile roof. It helps protect your home by acting as a secondary water barrier. Often, when roof tiles fall off, underlayment that's in good condition can temporarily keep water from getting into the home. However, immediate replacement of missing tiles is crucial to avoid additional roof damage. 

If you need to replace the roof over your attached garage, a roofing contractor can perform what is called a partial roof replacement that only affects garage roofing. However, it's important to keep in mind that only replacing a portion of your roof creates a situation where your roofing has two different lifespans. You will also miss out on the opportunity for a full roof warranty. In some cases, having two different roofs on your home could increase risks for leaks. When replacing the roof on a detached garage, homeowners have the option to make the project bigger by upgrading their home roof alongside their garage roof. However, this isn't necessary if your home has a newer, properly functioning roof. It is better to try to match the new garage roof to your home's existing roof instead.
