At least five years old. Bright Green Roof’s FAQ says to start at the five-year mark and to treat shingles that are 10 years or older. A roof past 20 can still qualify if it’s in good condition.
Age gets your roof in the door. Condition decides the rest. Two roofs put on the same year can wear very differently, so Chris looks at yours before he gives you a price.
Where your roof’s age puts it
| Roof age | What it means |
|---|---|
| Under 5 years | Too soon to treat. Keep the gutters clear and the roof checked. |
| 5 to 10 years | The earliest window. Treating now keeps a sound shingle flexible. |
| 10 to 20 years | Bright Green Roof says to treat at this age. Granules still on the shingle are what we want to see. |
| Over 20 years | Still possible if the roof is in good shape. Chris checks it closely. |
A roof that went on in 2021 hits five this year. The product can go on up to three times over a roof’s life, and Bright Green Roof rates each application for up to ten years. For roofs at the young end, read about treating a newer roof. For the full yes-or-no list, use our candidate checklist.
Why earlier beats later
Bush Intercontinental logs about 102 days a year at 90°F or hotter, on the 1991 to 2020 normals. Every one of those days bakes your shingles a little more. A treatment can keep a good shingle flexible. It can’t put back granules that already washed into the gutter. Wait too long and a roof can slide out of the window, and then a new roof is the only answer left.
Under five years? The C&D Annual Roof Checkup keeps an eye on it until it’s ready, with photos every year. Chris puts it this way: “Take care of your roof today, and it will take care of your home tomorrow.”
