Roofing FAQs, answered by experts

If you’re choosing between a roof overlay and a tear-off, opt for a tear-off and full roof replacement instead of a roof overlay if possible. The cost savings from an overlay can easily be eclipsed by repair costs, the effects of structural damage from the additional weight, and needing to replace your roof sooner than expected. A full replacement will last longer and is less likely to need damage repaired over time.

The green coloration that develops on copper roofs is called a “patina,” and it’s a result of mild oxidation on the surface. The oxidation process is not harmful to your roof. In fact, the surface corrosion acts as a protective layer and won’t spread to the core of your copper roof materials. The discoloration will progress much more quickly in damp or humid climates than it will in dry climates. If you don’t like the green color, you can seal your roof to preserve the shiny, rose-gold look.

A roof replacement can take anywhere from one to 14 days. For most homes, a full replacement that includes tearing off old materials takes about one to two days, though the average project can last up to 12 days. The exact timeline depends on several factors, including the roof's size and complexity, the type of roofing material, the crew size, and weather conditions. Certain materials take longer to install; for example, metal roofs can take seven to 14 days because the material is more difficult to work with than asphalt shingles, wood, or tile. A re-roofing project, where new shingles are installed over old ones, can take half the time or less. It's also important to factor in the time needed to obtain necessary permits. A professional roofing contractor will typically complete the job faster than a DIY approach.

Yes, capped chimneys should still be vented. Failing to vent a chimney will result in condensation buildup inside the chimney, which commonly results in mold growth. If mold begins to grow in a chimney, it frequently goes undetected and spreads quickly through the home. Mold and moisture can damage the structural integrity of your home, and exposure to mold can cause discomfort and illness in residents.

A roof's lifespan can range from 15 to 200 years, with an average of 25 to 50 years, depending heavily on the material, quality of installation, maintenance, and local climate. Asphalt shingle roofs are common and typically last 15 to 30 years; three-tab shingles have a lifespan of about 20 years, while architectural shingles can last up to 30. More durable materials have longer lifespans: metal roofs last 30 to 100 years, clay and concrete can last 50 to 100 years, and slate roofs can last up to 200 years with proper care. Regular maintenance, such as cleaning gutters and replacing damaged shingles, is crucial for extending the life of any roof.
