The dissimilar metals would be a big problem, on a Stone Coated Steel Roof. I was correct, it was Gerard that I talked to, who have assumed liability for the defective Dura Loc roofs.

This is the Man I talked with at Gerard Florida, his name is Derek.

And, right from their website, here are their roof cleaning instructions  http://www.gerardusa.com/sites/default/files/downloads/Gerard%20Cleaning%20Instructions%208-2013%20%281%29.pdf that we followed to the letter! In fact, though a 30% roof cleaning solution is called for, we only used a 25% solution.

It is always better to use a weaker solution, to protect the granule to metal bond.


The customer found us in a Google Search, and liked the fact that we have cleaned hundreds of these Dura Loc, Gerard, Allmet, and Decra Stone Coated Steel Roofs.

There are so many names for these, I get easily confused by them all. LOL, I just recently learned that Dura Lock, was the wrong spelling from you Andy.


It is also my understanding that the newer Dura Loc roofs are much better, and do not have the problems the old ones did.

Derek from Gerard Roofing Technologies tried to give me a sort of "history" of Stone Coated Steel Roofs.

He was very nice to me, and told me to Google defective Dura Loc  roofing products, to see all the lawsuits, and unhappy customers.

I had a call Thursday about a customer with a Dura Loc roof wanting me to repair it.  I think they were selling the home or in the process and the roof coating came up.  I explained it was not repairable and went into the Dura Loc issue some what.  I told them about your customer being offered new product but no installation was included.  I told them to call Gerard and file a claim, I am interested in what they tell them, I will post an update if she follows through and lets me know.

Hello everyone,

I also have a similar incident where granule is coming of the roof after our cleaning. I have done tens of metal roofs over the years but never had a similar issue. I found out that roofs are Dura Loc and they were installed after hurricane Wilma and were never cleaned before.

 The Condo Association is blaming our method of cleaning. We have used light bleach solution (less than 30%) that was sprayed on the roofs without pressure off a boom lift (no walking at all). A couple of weeks later, we received complains that granule is coming off.

The condo has 9 large buildings but we only cleaned 1 building. I have no idea how to rectify this problem and hopping to get some guidelines on what to do here.

Here is a lawsuit filed by a Florida Condo Association I found in a Google Search-


Dura-Loc Facing Suit Filed By Condo Association

While Dura-Loc has not yet faced a class action lawsuit from consumers, the company was recently named in a lawsuit filed by Cross Creek of Fort Myers Florida Single Family Condominium Association, Inc. In the lawsuit, the condominium association alleges it hired a company known as H20 Cleaning & Restoring, LLC to clean the roofs of buildings fitted with Dura-Loc shingles. Shortly after the cleaning company applied a foaming agent to the shingles, the association noticed widespread damage, including discoloration, on the treated roofs and surrounding areas (i.e. sidewalks, gutters). 

The association first sued the cleaning service for allegedly cleaning the roofs with the wrong cleaning solution; however, the case was later amended to include Dura-Loc as a defendant. This is because lawyers for the association had reason to believe the shingles were defective and could weaken even when fitted and maintained properly. The suit alleges that Dura-Loc’s Signature series shingles suffered granule loss (i.e., had begun to deteriorate and shed their protective layer), which resulted in property damage and other problems.

What’s Wrong with the Shingles?

Dura-Loc’s Signature shingles are coated in granules –  fine, sand-like grains often made from minerals or ceramic material fixed in place with adhesive or asphalt. The granules provide strength and durability to the shingles, and protect homes and businesses from moisture intrusion and other damage. It has been alleged, however, that these shingles were defectively designed. According to these allegations, the granules can dislodge, washing off the shingles and weakening the entire product. This alleged granule erosion may lead to discoloring, streaking, and exposure of the roof underlayment. If underlayment is exposed to natural elements it can easily be damaged, leading to further complications and requiring repair and/or replacement of the shingles, according to the suit.

Dura-Loc has been accused of manufacturing a sub-par product and failing to honor warranties that guaranteed the surface coating of the shingles would not deteriorate. If you have suffered property damage or related problems with Dura-Loc’s Signature Series shingles, attorneys working with ClassAction.org would like to hear from you concerning a possible class action lawsuit. 

I had a Dura Lock roof system installed on our new home in August of 2006.  For a couple of years we have noticed some grandeur (stone) coming off.   Upon a complete inspection this year and it is coming off all over the roof.  We paid $38,800.00 for this roof and don’t know what to do.  I have read a lot on line and it doesn’t look that good for the home owner.  We have a warranty number for there Signature Series.  It is 400394,06.  Thank you and please let me know if I can be of more help.

Derrick was a great guy to talk with, and he assured me that Dura Lock Roofs used a cheap glue and construction methods, one reason they ain't around anymore!
