How To Apply Elastomeric Roof Coating

by | Apr 11, 2022

The southwest of America is home to acrylic elastomeric roof systems. These roof coatings are water-based and are applied every 4-6 years to water proof and protect southwest style roofs. Southwest Arizona is also home to tile roofs, shingle roofs, some metal roofs, but the best Tucson roof contractors must have extensive knowledge on how to apply elastomeric roof coatings. Applying these coatings is not difficult but there are a few things to keep in mind when applying them.

Only Use Premium Roof Coatings

Cheap coatings are thinner and don’t apply very well. They go on thin and are difficult to get to uniformly lay down on the roof. Cheap coatings also harden quicker which means they will crack sooner. Premium coatings are thicker, have bleed-block technology, and remain rubberized longer. When they are applied to the roof they go down in a smooth fashion and spread uniformly across the roof. Desert Sky Roofing uses the top of the line Tucson Rubberized 7000 roof coating almost 100% of the time because it is the best premium roof coating on the market.

Roll the Coating On, Don’t Spray It On

Some roof coating contractors spray roof coatings on the roof. Unfortunately, it is very easy to apply the material very thin and not get the proper amount of coating when spraying. If your roofing contractor insists on spraying the rubberized coating, have a serious talk on how much coating is going to be applied. Rolling the coating on the roof helps ensure the proper thickness of the roof coating.

Use Thick Roller Naps When Rolling Roof Coating

When learning how to apply elastomeric roof coating, it is easy to overlook the roller nap thickness. A thicker nap ensures more coating is brought from the bucket to the roof. It also allows the coating to go on thicker. We prefer using a 1″ – 1 1/4″ nap to apply the coating. Using a nap that is thinner will only lead to the coating being pushed around the roof and not rolled on in a uniform fashion.

Apply Cool Coating Using Criss-Cross Roller Movements

Some elastomeric coating companies will write on their application instructions to put the first coating on in one direction and the second coating on in the opposite direction. This is to ensure a criss-cross pattern that ensure the roof is properly coated. The criss-cross pattern can be applied on both coats. We recommend applying the coating using an “X” pattern on every dip into the bucket. By doing this, the coating is applied the same thickness and the area in your pattern is properly touched by coating.

Apply Each Rubberized Coating No more Than An 1/8″ Thick

Many wrongly think that the more the coating the better. That is not the case. Water based roof coatings will split and crack if they are applied too thick. This is because the top dries quicker than the inside and this causes a fissure in the coating. We recommend keeping the coating no thicker than 1/8″ thick per coat. This will ensure the coating is not applied too thick.

If you’re a Tucson homeowner in need of shingle roof replacement, getting a detailed and honest estimate is a crucial first step. Not all roofing contractors are the same — and not all roofs are, either. The Arizona heat, monsoon winds, and sun exposure make it essential to choose a roofing company that understands local conditions and uses the right materials. Asking the right questions helps you feel confident in your roofing contractor and ensures your roof repairs or full replacement will be done correctly.

Below are seven smart questions you should ask your estimator or Tucson roofing company before hiring a roofing company in Tucson:

Is the company licensed, bonded, and insured?

This should be the first question you ask any roofing contractor. Arizona law requires roofing companies to be licensed, bonded, and insured. A licensed contractor has met state requirements and carries the appropriate insurance in case something goes wrong. If your estimator or roofing company can’t provide their ROC number and proof of insurance, that’s a red flag. Hiring a properly licensed roofing company protects you from liability and ensures the job is done to professional standards.

What warranties do they offer on materials and labor?

Warranties are a key part of any roofing job. You’ll want to know how long the shingles are warrantied by the manufacturer and whether the roofing company backs up their own workmanship. For example, laminated (architectural) shingles — which are now the standard since three-tab shingles are no longer available in Arizona — often come with extended warranties and superior wind resistance. Be sure to get all warranties in writing, and ask your roofer estimator to walk you through what’s covered.

What type of underlayment do they use?

The underlayment is a critical component that sits beneath your shingles and adds an extra layer of protection against leaks. In Arizona’s intense climate, a high-quality synthetic underlayment is best. It resists heat, doesn’t absorb moisture like felt paper, and holds up better over time. A reliable roofing company will always include synthetic underlayment in their shingle replacement process. If your estimator doesn’t mention it — ask.

How long does the shingle replacement process take?

Time matters, especially if you’re trying to schedule around monsoon season or HOA approvals. Ask how long the shingle roof replacement will take from start to finish, including tear-off, installation, and cleanup. Most shingle roof replacements can be completed in one to three days depending on the size of the home, weather conditions, and any needed wood repairs. A professional roofing contractor should provide a clear timeline in your estimate.

Will they inspect and replace damaged wood decking if necessary?

Removing old shingles often reveals damage underneath. It’s important that your roofing contractor inspects the wood decking and replaces any rotted or warped sections. A proper estimate should outline that any necessary decking repairs will be included, and the estimator should explain how those costs will be handled if they arise. Skipping this step can compromise the entire roofing system.

Would ridge vents be a good option for your roof?

In Tucson, keeping your attic cool reduces heat transfer into your home and helps your roof last longer. Ask your estimator about installing ridge vents or upgrading any existing attic ventilation. Proper ventilation helps reduce moisture and heat buildup, improves energy efficiency, and is often overlooked by less experienced roofers. A well ventilated roof will last you longer.

What brand of shingles does the roofing company recommend?

While most roofing contractors, including Desert Sky Roofing, can install all major shingle brands, the estimator should be able to recommend a brand or line that performs best in Southern Arizona’s climate. Laminated shingles with a high wind rating are ideal for Tucson homes due to their durability and impact resistance. Your estimator should explain the differences clearly and offer a color and style selection that matches your home.
