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.

Hail damage is bad for a roof because it can leave the roof vulnerable to the elements. Hail may leave more than dents or scratches behind. It can actually cause the shingles to crack, which means water can leak into your home from the roof. Hail can also wear down the granules on the shingles. Without these granules, the shingles are weaker and more vulnerable to the elements, particularly wind. If the hailstorm is accompanied by high winds, it may take your shingles with it.

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.

You should plan on waiting as long as it takes for the roof deck to dry out completely if it gets wet. In most cases, this will take about 24 hours, but it could take longer if you have shading on your roof or cloudy weather after the rainfall that prevents the sun from drying the material.
