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.

Roofing estimates and inspections are not the same thing. Roofing inspections (whether done with a drone or by the traditional method) help you find any damage or defects on a roof. You will pay a set fee for a roofing inspection and use it to get certification or to determine whether repair or replacement is necessary. Beware of unsolicited contractors coming to your home and offering a so-called free roof inspection—these are often scams.

Roofing estimates, on the other hand, are typically free and offered by a roofing company hoping to earn your business. Some roofing estimates are performed with drones, while other companies will still opt to send people up onto the roof. Either way, the estimate is for roof repair or replacement costs the company wants you to hire them for.

The best way to prevent wind damage to your roof, especially if you live in an area prone to hurricanes, tropical storms, or tornadoes, is to invest in a roofing product with high wind resistance. Look for the ASTM D3161 and ASTM D7158 ratings to see the specific wind speeds your roofing product can withstand. Impact-resistant shingles have the highest wind resistance ratings and will give you the best chance of avoiding wind damage.

Unfortunately, there’s no definitive answer to this question, but the wind rating of your shingles will give you a good idea of what wind speeds can damage your roof. If you’re concerned about damage, inspect your roof following windy conditions to look for signs of wind damage to your shingles. When in doubt, consider hiring a professional who fixes roofs to carry out an expert inspection. Remember that hurricanes, tropical storms, and tornadoes are likely to cause the most damage, but even severe thunderstorms can bring winds that compromise your roofing system.
