A building permit is a requirement by federal and local governments for any construction or modification of existing structures. The records alongside building permits contain vital information such as when the roof was installed, the last repair date, and roof replacement activities undertaken.

If your home had previous owners, you can obtain the permit from the local authorities or online. You’ll need to provide the home address and other home details to prove ownership and easily identify the permit.

Alternatively, if you’re a new homeowner, you can check with the contractor who installed your roof. They can provide you with your building permit or roofing company receipt, indicating the exact installation activities.

Inspect Shingles

As shingles are constantly exposed to various weather conditions, their appearance can provide valuable information on your roof’s overall health and longevity. For instance, shingles with granular loss, curling edges, splits, or cracks could indicate a roof in its later stages.

During the inspection, start by inspecting the missing shingles closely. If you’re unable to climb up your roof, you may have to use binoculars and inspect from the ground. Also, check if there are any loose granules or bare spots due to UV radiation exposure.

You can also inspect other roof structures from the interior, such as the damaged roof valleys, attic, insulation, siding, and other visible components. If you notice some leaks, water stains rusting, or deterioration of the structures, this could mean the shingles above are worn out, indicating long-term exposure to severe weather conditions.

Examine Roofing Material

Accessing your new roof to understand the type of material used can give you a clue about its age. Whether it’s asphalt, wood, metal, or tiles, you can use the expected durability of the material to gauge when it was installed.
