Roof Rejuvenation Spray

What roof rejuvenation is

Asphalt shingles are made with oils that keep them flexible and waterproof. Sun and weather slowly bake those oils out, so shingles turn brittle, shed granules and crack. A rejuvenation treatment, also called a bio-oil spray, soaks into the shingles to put those oils back, renewing the roof you already have.

Make shingles last

Adds up to 5 years to the life of asphalt shingles that are unbroken and in good condition.

Save money

Costs up to 80% less than the full cost of replacing a roof.

Save time

The treatment takes about 2 to 4 hours.

Why it matters here

In hot months

Sun and heat dry shingles out. Added oils help them stay flexible instead of turning brittle.

In cold months

Dry shingles get stiff and crack more easily. Restored flexibility helps them hold up to storms and impact.

Is it right for your roof?

Usually a good fit

  • Asphalt shingles that are aging but still lie flat and intact
  • Shingles that look dry or faded or are shedding some granules
  • You want more years before paying for a replacement

Probably not the answer

  • Active leaks, missing shingles or storm damage
  • Shingles that are badly curled, cracked or bald
  • Metal, tile or flat roofs (we have other solutions)

Common questions

How long does a treatment last?

Up to 5 years on asphalt shingles that are unbroken and in good condition. Actual results depend on your roof's age, condition and sun exposure, and the benefit fades gradually as the oils dry out again.

Can it be done more than once?

Yes. Rejuvenation products are generally designed to be reapplied after several years, a limited number of times. Each repeat tends to add less than the first, because the shingles keep aging.

Will it affect my shingle warranty?

It can. The trade association for shingle manufacturers advises against treating shingles after they are installed, and at least one major manufacturer states that its product warranty no longer applies once a rejuvenator is applied. If your roof is still under a manufacturer warranty you want to keep, check with the manufacturer first. We'll talk this through at your inspection.

Has this been tested?

Yes. Lab testing on soy-based rejuvenation treatments has shown better flexibility and granule hold on aged shingles after treatment. Results on your roof depend on its age and condition.

Will it fix my leak?

No. A leak needs a repair. Rejuvenation treats the shingle material; it does not fix flashing, decking or damaged shingles.

Will my roof look different?

The treatment is a plant-derived oil made from soy methyl ester. Sprayed on, it mimics the petrochemical oils asphalt shingles are originally made with and puts back the oils they lose to weather and age. Because it soaks into the shingle instead of sitting on top like paint, it does not coat or recolor your roof. Shingles may look slightly darker at first.

What weather do you need?

A dry roof and a dry forecast. We schedule around the weather.

Is it safe for my family, pets and landscaping?

Yes. The treatment is a natural, soy-based oil derived from plants.

What kinds of roofs can be treated?

Asphalt shingle roofs only. We have other solutions for metal, tile and flat roofs.

What does it cost?

Most roofs fall between $1.50 and $2.25 per square foot of roof, depending on steepness, height and shape. Use the rough price calculator for your home. Maintenance plan members save 15%.

What if my roof doesn't qualify?

We'll tell you, show you why, and recommend a repair or replacement instead. The inspection is free either way.

Every roof has a solution. We'll help you find yours.
