Farmington Hills homeowners. A roofer, not a call center, gets back to you.
A dry roof is not always a dead roof
Plenty of Farmington Hills homes had their roofs replaced at some point in the last couple of decades, and many of those shingles are now in the middle of their life. They aren’t leaking, but years of Michigan sun on the open slopes and winters of freeze-thaw have baked out some of the oils that keep asphalt flexible. You see it as granules in the gutters, edges that look dull and stiff, and a roof that seems older than it should.
That is the window where rejuvenation makes sense. The treatment is a safe, bio-based product sprayed onto the shingles that puts oils back into the asphalt, so they stay flexible through another round of cold winters. One application can extend roof life by up to 5 years, and repeat treatments can add up to 15 years in total.
It only works on a roof that is still sound. If we find soft decking, failed flashing or shingles that are curling and cracked, we tell you and show you the photos. In that case a repair or a replacement is the honest answer.

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.

Sun on one side, shade on the other
On a wooded Farmington Hills lot, two sides of the same roof can age very differently.
Many homes in Farmington Hills sit under mature trees. The slopes that get full sun dry out and lose granules first, while shaded slopes stay damp and can pick up moss. Both matter when we decide whether a roof is a good candidate, so we look at every slope instead of judging the roof from the driveway.
Michigan winters add their own wear. Freeze-thaw cycles and snow sitting on the roof are hardest on shingles that have already gone stiff, which is why rejuvenating while the roof is still sound pays off.
Sun-baked slopes
South and west faces that dry out first and shed granules into the gutters.
Every slope checked
Shaded faces inspected for moss, soft spots and lifting edges before we recommend anything.
