Dry shingles on a sound Dearborn roof
A lot of Dearborn homes got a new roof sometime in the last 10 to 15 years, often after the old layers finally came off. Those roofs are usually still watertight, but the shingles are starting to show their age: stiffer edges, granules in the gutters and a faded look on the sunny slopes.
That is the stage where rejuvenation makes sense. Asphalt shingles stay flexible because of the oils in the asphalt, and Michigan summers bake those oils out while winter freeze-thaw cycles flex the shingles every time the temperature swings. Restoring the oils helps them bend instead of crack. One application can add up to 5 years, and repeat treatments can add up to 15.
It is not a fix for every roof. On older Dearborn houses we sometimes find soft decking, a second layer underneath or chimney flashing that has already failed, and no treatment solves those. So Scott looks at the roof first, the crew photographs the shingles, flashing and vents, and we tell you honestly whether you are a candidate or whether a repair or replacement is the better use of your money.
What the treatment actually does
Rejuvenation works on the shingles you already have. Here is what happens on your roof.
We check the roof first
We walk the roof and look at the shingles, decking, flashing and vents, and photograph what we find.
Oils go back in
The bio-based treatment soaks into the asphalt and replaces the oils that sun and weather have dried out.
Shingles flex again
Restored shingles bend with temperature swings instead of cracking, and hold their granules better.
Repeat to add more years
Each application adds up to 5 years. Repeat treatments down the road can add up to 15 years in all.
Rejuvenate, repair or replace?
Most roofs we inspect fall into one of three groups. Some have a few problem spots on an otherwise good roof, and a repair is the right fix. Some are worn out across the whole surface, with soft decking or shingles that are curling, cracking and shedding everywhere, and those need a new roof.
In between are roofs that are aging but still sound. Those are the ones rejuvenation is made for. The treatment costs a fraction of a replacement, and it buys time on a roof that would otherwise keep drying out. Sometimes the answer is a combination: fix a lifted flashing or a few damaged shingles, then treat the roof.
Your written estimate lays out the options side by side, with photos, so you can decide without anyone pushing.

Good candidates and poor ones
Rejuvenation only works on a roof that is still sound. We will tell you which side of the line yours is on.
Good: brittle but flat
Shingles that feel stiff and have lost some flexibility, but still lie flat and stay sealed.
Good: some granule loss
Grit in the gutters and a faded, dry look, without bare spots across the roof.
Good: solid decking
No soft or spongy spots underfoot, and flashing and vents that are in good shape.
Poor: curling and missing
Shingles that are cupped, curled, cracked through or already blowing off in storms.
Poor: active leaks
Water stains on ceilings or wet decking mean water is past the shingles. That needs repair first.
Poor: soft decking
Rot or sagging in the wood under the shingles can’t be treated from the top.

Which Dearborn roofs are good candidates
Shade, sun and roof age all decide whether a treatment is worth doing on your house.
Dearborn has a mix of conditions on the same street. Roofs under the big old trees in west Dearborn and near the Rouge River stay cooler but hold moisture and debris. Roofs on open lots, and the south- and west-facing slopes of most homes, take the full summer sun and dry out first. We look at each slope separately, because the same roof can be a candidate on one side and need repairs on another.
Sun-baked slopes
South- and west-facing slopes losing oils and granules while the decking is still solid.
Mid-life roofs
Roofs put on in the last 10 to 15 years that are still watertight but turning brittle.
Inspected first
Soft decking, failed flashing or hidden layers mean repair or replacement instead.
