Underlayment is required by building code, so any roof installed without it is technically against code. The underlayment acts as the second layer of defense against water, so installing a roof without underlayment means a much higher risk of roof leaks. You’ll have the best chance of avoiding roof leaks if you install drip edge flashing covered by underlayment, and then install your roofing material over that.

The terms “roof sealant” and “roof coating” are used interchangeably to describe the rubber, silicone, polyurethane, or acrylic product applied to the roof’s surface for waterproofing and UV protection. Products like roof caulk can also be called “roof sealant,” but the term is more commonly used for the protective coating.

It’s possible to walk on a clay tile roof, but you run the risk of breaking or cracking the tiles if you’re not careful, so it’s best not to walk on it if you can avoid it. If you or a contractor needs roof access, be sure to distribute your weight evenly and step on the portions of tile that are also supported underneath, which depends on your tile design. Walking on any roofing material is inherently dangerous, so wear rubber-soled shoes and use safety equipment if you need to access your roof.

No, there’s no specific building code that requires a roof overhang. However, installing your roof with the standard 2-inch overhang is good practice, as it helps direct runoff away from your fascia boards and roof decking and into your gutters. Some overhang is especially important in areas that see heavy rainfall and snowfall, as the risk of water getting under the roofing material and causing water damage is much higher.
