In the late 1990s and early 2000s, roofs generally lasted 20 to 25 years. However, since then, due to advancements in materials technology and installation techniques and training, a roof built today by a reputable contractor with good materials might last upwards of 40 or even 50 years. Some contractors even offer 50-year warranties.

If your roof needs repairs rather than a full re-roof, our calculator will not be accurate. However, repairs are generally much less expensive than full replacements. For an accurate repair estimate, you'll need to speak with a licensed roofing contractor. Most reputable contractors offer free estimates.

Skilled crews can usually have a new roof installed within three days. This will depend on the size of your home, its pitch (steepness), materials, and shape.

Our estimates are based on recent jobs completed by our licensed roofing partners in San Diego. These estimates take into account your home's size, materials, and pitch (steepness), as well as things like wood damage, tear-off for multiple layers of materials, and solar reinstallation.
