Yes, thatched roofs are legal in most areas in the U.S., but you should always check your local building codes to ensure there are no restrictions in your particular area before installing one. Even where they are legal, you’ll usually need to apply fireproofing to the roof to keep it up to code. Keep in mind that a new roof might not increase home value as much if you choose a thatched roof, as they aren’t common in the U.S. and might not be as desirable to many home buyers.

Properly installed chimney flashing can last anywhere from 15 to 50 years. However, flashing generally only needs to be replaced when it is damaged, corroded, or no longer creates a watertight seal. Several factors influence its longevity, including the material type, quality of installation, and local climate. For example, copper flashing tends to last longer than galvanized steel. Large storms and extreme weather can also damage flashing, potentially requiring earlier replacement. To ensure its longevity, it is recommended to have your chimney and roof inspected annually. A professional can assess the flashing's condition and recommend any necessary repairs.

Skipping the installation of a drip edge or gutter apron can lead to significant water damage. Without this component, water is more likely to seep under roofing materials or leak behind gutters, damaging the fascia, soffits, siding, and even the interior of your home, such as the attic. Over time, this moisture can cause rot, mold, and deterioration. In colder climates, a missing drip edge also increases the risk of ice dams, which can lead to expensive repairs. A drip edge is an essential part of a roof's drainage system, and some local building codes may even require its installation to protect the home from water damage.

No, you should not close or cover your gable vents in the winter. While it might seem logical to block cold air, heating your home creates hot air that rises and can cause condensation in the attic. If the vents are covered, this moisture becomes trapped, creating an ideal environment for mold and mildew. Keeping the gable vents open ensures proper ventilation, which helps dry out the attic, maintain even temperatures, and prevent moisture-related damage.
