TIA

My roof is GAF Timberline, 17 years old, probably will need to be replaced in another 5 years. I went to a local home show and found a company called Roof Renew that sprays an agricultural bio-oil solution on the roof that re-saturates the asphalt shingles extending their life. The cost for my 30 square roof is $3,000.00, new roof probably at least $15,000.00 to $20,000.00. There are several similar products on the market. Has anybody had any experience or information about this process.

How It Works

As asphalt shingles age, the petro-chemical oils that maintain the shingle’s flexibility and performance begin to evaporate, and problems begin to develop. Roof Renew applies an all-natural bio-based solution that replaces lost petro-chemical oils, bringing the shingle back to life. The first application is guaranteed to extend the life of your roof by 5 years, and up to 15 years with 2 more applications every 5 years.


What Roof Renew Treatment Does

Rejuvenates aging asphalt shingles so they don’t have to be replaced

Extends the life of the shingles by 5-15 years

Improves granule adhesion by 86%

Reduces damage caused by wind and hail

Restores shingle color

Kills algae and moss, and hinders re-growth

Keeps shingles out of landfills (more below)

Improves fire resistance by 40%.


Lab Tested

Independent testing by PRI Asphalt Technologies compared treated vs. untreated shingles with the following findings:

Granular adhesion improved by 86%.

Flexibility improved from “fail” to “pass”.

Hail impact was improved.

Fire resistance improved by 40%.

It's definitely intriguing... but there's usually more to needing to replace shingles than merely dried out shingles. Sometimes they can get damaged, the nails will pop-up, etc... but either way, that's still pretty cool. Are you going to do it?

It sounds like they want you to redo it every five years. Good shingles will last 25 years even in the Arizona sun. Is it really cost effective?

I was just looking at that earlier this week. There is another company advertising the same process but I can't remember the name. How many square feet is 30 square? I've got 2000 square feet. Just want to get an idea of ballpark cost before I put my name in their database.

30 square is 3000 sq ft so you would be at 20 square for your 2000 sq ft roof.

Thank you. Might be a little cheaper down here. I'm on the edge of Metro and Farm Country.

Reading some review sites about the process, most encountered higher costs than quoted because the application company usually found other 'issues' that needed to be addressed. Something to be aware of and consider.

I am still looking for more information as this is a fairly new product. I am going to get a couple of bids on a new roof and compare the cost on an annual basis. With a new roof I know exactly what to expect, I would be taking a chance that the rejuvenation really will work.

Does an all-natural bio-based solution replace lost petro-chemical oils ? I have to wonder what's in that all-natural bio-based solution.

I know railway ties are treated in a petroleum saturation of some sorts when new, to preserve them. I have gotten used ones before and "painted" them with used motor oil.

I wonder if one can not "paint" a roof with linseed oil.

I have talked to a local company about this a year ago and basically it only works if your shingles are already in good condition. It will not fix them if they have started to curl or have lost too much of the grain.

From my discussions with them, to me it sounded more like snake oil. Maybe it does help extend the life if done every 5 years as suggested, but this is still too new of a process IMHO.

I ended up biting the bullet and replaced the shingles.

I wonder if it is made from recycled cooking oil. There is a product used for dust control on some dirt yards such as large lumber yards, that smells like french fries.

While such a application does sound interesting, I have to ask what any warranty covers?
Shingle failure due to damage is probably not covered but, a lot more information is needed before I'd take a $3K risk. Most shingles fail due to wind, hail or just sun damage. What's covered if there is a warranty?

Rams

Check with your house insurance before you do it. My insurance has all kind of odd rules. They were going to drop coverage because not all of the shingles were the same color. (You try to find shingles after a hurricane)
