How DSR Will Coat Your Roof – Step by Step

Inspect the Roof

before-roof-coatingBefore we coat or repair a roof, we first need to see what we are up against.  In this visit we will note the defects, the needed work, and determine the square footage of the coverage area so we can order the proper amount of roof coating.  We will take the “before” photos and provide an estimate for recoating their roof with the top of the line rubberized roof coating.  The estimate will include the approximate square footage of materials, the expected number of 5-gallon buckets of material, and the “out-the-door” price. We do not believe in hiding prices or adding on work after the job has been started to try to get more money. Granted, on the very rare occasion it is necessary to add extra work, we may need to do so but that is not the norm with Desert Sky Roofing. We strive to be the most open and informative roof coating Tucson contractor in the business!

Remove Debris From Roof

Santa Fe style roofs seem to collect leaves and debris of all sorts because the house itself resembles a large bowl!  We will collect that debris and remove it from the roof before we pressure wash.

Spray Down With Tri-sodium Phosphate

Tri-sodium phosphate is the best cleaner for acrylic elastomeric roof coatings.  We use a garden sprayer and spray this over the roof before pressure washing.  This will give the TSP a moment to soak into tapplying-tsphe roof coating.  Many Tucson roof coating contractors skip this step.  We cannot tell you that the roof coating will not adhere if it is not cleaned with TSP, but we can say it is a better practice to use it on every roof.

Pressure Wash Roof



Using high pressure water loosens the dirt and is the best practice for cleaning your roof before it is coated.  Pressure washing in conjunction with using TSP is the best practice for preparing coated roofs.

Let the Roof Dry

Before coating a flat roof or an elastomeric coated roof, it is necessary to allow the roof to dry.  In Southern Arizona, roofs dry very quickly, so the drying process may only take a couple of hours, however, sometimes it can take a day or so.  The key to knowing how long is knowing what shape the roof was in when we pressure washed and knowing what the weather is like. Our professionals at Desert Sky Roofing are trained to know if a roof is properly dried before they apply the first coat.

Patch Roof

White coated or tan coated roofs often crack. This is because the expansion and contraction of materials causes a breakdown in the coating.  Wherever a crack exists that penetrates the roof paper, corners, crickets, scuppers, or walls there is a need for a polyester patch. applying-roof-patchPolyester (tietex) patching is the #1 fix for these type of roof issues. These are applied by layering a polyester patch between two coats of elastomeric crack and joint filler like Tucson Rubberized Coatings 501-W-P product) or elastomeric top coating like Tucson Rubberized Coatings 7000 product).  Once this patch dries it will become part of your roof system.  The number of patches varies from roof to roof but it is not unusual for a roof to have 15-20 patches.

Reinforce Scuppers


Scupper cracks lead to scupper leaks

(Santa Fe style roofs). Eighty-five to ninety percent of all roof leaks in elastomeric roof systems comes from scuppers. Scuppers are the drains that remove the water from the inside walls (parapets) of Santa Fe style roofs.  The area where the scupper meets the roof system often cracks due to movement in the home.  This causes an opening into walls which usually allows water to drain into your home.  The least pinhole can become a huge leak.  At Desert Sky Roofing we believe in being proactive. If needed, we will scrape the old material out of the scupper and reinforce the scupper with either polyester fabric or at a minimum crack and joint filler before coating the roof.  This will do much toward preventing future problems.

Reinforce the Penetrations

Penetrations are the holes or vents that penetrate through the wood decking and stick out on top of your roof. These areas are prone to cracking because of the movement of materials from heating and cooling.  We will put crack and joint around these areas before we coat the roof to help prevent leaking.

Reinforce the Edges

(Mostly ranch style homes). Many coated roofs have a pitched roofline that ends with a drip edge.  These drip edges move very frequently and end up with tiny cracks on the top edges. These cracks allow water to penetrate around the facia boards which leads to premature rotting of the wood.  We will fill these cracks with roof coating or crack and joint filler and will sometimes recommend using polyester fabric patching around the edges.


Roof edge cracks lead to rotted facia.

Apply the First Coat

After all the patching and reinforcement of critical areas, we will then start coating the roof. We follow the manufacturer’s recommendations and coat the roof according to their standards.  Not all coatings are the same, and not all will last the same. roof-coating-contractorWe use Tucson Rubberized Coatings 7000 product because we believe it to be the best acrylic elastomeric coating on the market.  They recommend the coating be applied between 100-120sqft per gallon of material. This means if you have 1200sqft of coverage area, we will be applying between 10-12 gallons of material per coat. When we apply the coat we also follow the “crisscross” recommendation.  We do this by laying down the initial roller pattern in one direction and flattening it out in the opposite direction.  This ensures the coating is evenly and appropriately applied.

Allow the First Coat to Dry

In many cases the coating is dry enough to walk on withing two hours or less. This doesn’t mean the coating is cured, but it is ready for the second coat, if one is going to be applied.  A good rule of thumb is that if the coating doesn’t stick to your shoes or pull up when standing on it, it has dried enough to apply the second coat.  Sometimes we must wait a full day, sometimes we only need to wait a few hours before applying the second coat.  Of note, you will NEVER see our company pressure washing and applying two coats in the same day.  We feel this is calling it too close for necessary dry times.

Check For Extra Patching

Polyester fabric patches

Just before we coat the roof the second time we will check to see if more patches are needed. Most all the patching will be complete, however, sometimes we will find some areas that need additional patching or that we believe should be further addressed before applying the second coat.

Apply Anti-ponding Material

If needed and agreed upon, we prefer to apply anti-ponding material after the roof has been sealed with the first coat. Some anti-ponding products are porous and can allow water through. Anti-ponding-materialThat is why it is important to seal the roof first so there is very little chance of water making it into the house. The ponding material will be sealed when the second coat of elastomeric is applied.

Apply Second Coat

Assuming the roof is getting a second coat of elastomeric, after the first coating is dry we will apply a second coat also using the crisscross pattern.

Perform a Quality Inspection

Most roof companies simply collect their money and forget about your roof.  We will return to do a quality inspection and check all the work that we have completed after the materials have had a chance to cure.  At Desert Sky Roofing we want to create a long-term relationship with our clients so ensuring our work was top-notch is extremely important to us!

Perform a Free Inspection Prior to the Warranty Expiring

At Desert Sky Roofing we offer a free inspection just before the warranty expires. If our clients call us before their warranty expires, we gladly show up and do a thorough inspection of the entire roof perform touch ups as needed.

A Service Plan That Fits Your Roof – Five Possible Plans for Your Coated Roof

At Desert Sky Roofing LLC, we offer four different roof servicing plans for your elastomeric roof. We realize that not every roof has the same needs and sometimes it can vary. We are not going to try to sell you something that you do not need and will provide you with the proper option for your roof.  Some roofs need extensive work while others may only need touch ups.  Therefore, we have devised three service plans that will fit almost every flat or built-up elastomeric coated roof. Here are our plans:

1) The Re-Coating Service

This is for roofs that have not been coated in some time or that were not coated properly. Roofs in this category generally need one or two full coats of elastomeric to become serviceable again. If your roof has not been coated in over three years, it will likely fall into this category.  However, there are always exceptions.

2) The Renewal Service

This plan focuses on reflective coated roofs that have a decent coating on them but could use some cleaning and some minor touch ups.  In this plan we will also reinforce all the scuppers, penetrations, drip edges, and A/C jack stands so leaks do not occur.  The best candidate for this plan is a roof that was coated properly in the past 1-3 years and has very minimal wear and tear.  We offer this for those who want peace of mind, or who are selling their home and want a licensed professional to spruce up the roof before it is sold. In this plan, we provide a 1-year warranty on the entire roof and a 2-year warranty on all touchups and work that we performed.

3) The Re-touch Service

This plan is for those who want to ensure they make it through the monsoon season without any leaks.  Most roofs in this plan have been recoated in the last 1-3 years and have minimal defects. The difference between this plan and the Renewal Plan is that here we are only going to touch up what is necessary and we do not provide an additional 1-year warranty to the entire roof. We will provide a two-year warranty for any work we do perform. This plan is perfect for snowbirds who want to head out of the heat for the summer and not worry about their roof until they return.

4) The “Do-it-yourself” Service

What? A roof company that will teach you to do it yourself? Yes. We feel if you can’t beat em, join em!  With the “Do-it-yourself” plan we will set up a time to come to your house with all the materials you will need to work on your roof. We will walk the roof with the “do-it-yourselfer” and point out all the needs for the roof.  After discussing how to repair the roof we will then pressure wash the roof so that it can be recoated the next day by whomever wishes to do the work.  Of course we are in the business to make money so we do charge a fee for pressure washing and delivering the material but the wisdom is free!  Also, for a small fee we are willing to deliver the buckets of material to the roof after pressure washing.  If you think you are up for some hard work and want to do it right, give us a call and we will assist you with the knowledge and materials needed to recoat your roof the correct way.

5) The Pressure Washing Service

If your roof doesn’t need coating and simply needs to be pressure washed, we are willing to do that for you.  Pressure washing is always a great idea for coated roofs because it cleans the debris and removes the grime which allows the coating to last longer.

Whether it has been a while since you coated your roof or just a year ago, we have a plan that fits your needs. At Desert Sky Roofing we are not going to sell you something you do not need.  In fact, we are willing to tell you that you don’t need work at all!  Rather than try to only sell the most work possible to a client, we would rather provide you with an honest opinion of what is actually needed and an option for doing that work. Unlike many of the blow and go shady roof companies who want to take your money and run, we are seeking for your long-term relationship with the Desert Sky Roofing Family!  Give us a call today so we can determine what plan fits better for your roof!
