More years from a sound Southfield roof
Plenty of Southfield homeowners replaced their roof sometime in the last ten or fifteen years and are now watching it age. The shingles are turning a little gray, granules are showing up at the bottom of the downspouts, and the south-facing slope looks drier than the rest. The roof isn’t leaking and the decking is solid. That is the roof rejuvenation was made for.
Asphalt shingles stay flexible and waterproof because of the oils in them. Michigan summers bake those oils out, and winter freeze-thaw works on shingles that have gone stiff, so they crack and shed granules faster. Our treatment is a safe, bio-based product that restores those oils, extending the life of a sound roof by up to 5 years per application and up to 15 years with repeat treatments.
It is not a fix for a failing roof. If we find soft decking, widespread cracking, missing shingles, multiple old layers or active leaks, we tell you rejuvenation is the wrong choice and show you the photos. On a roof in good shape, it lets you put off a tear-off and plan for it on your own schedule.
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 Southfield roofs are good candidates
Rejuvenation works on roofs that are aging but intact. On Southfield streets, that means checking each house on its own terms.
Southfield’s houses may date from the 1950s and 1960s, but the shingles on them range from brand new to worn out. The best candidates are roofs installed in roughly the last ten to fifteen years that are drying out evenly. Heavy shade from the city’s mature trees changes the picture too: shaded slopes stay damp and can grow moss or algae, while open slopes take the full summer sun. We look at every slope before we recommend anything.
Sun-facing slopes
South and west slopes dry out first, so we check every slope, not just the one you see from the street.
Honest assessment
We check flexibility, granule loss, cracking, soft spots and the number of layers before recommending anything.
Same look
The treatment doesn’t change your shingle color, so the house looks the same from the street.
