What Is the Difference Between Traditional and New Coating

Roof coating is a membrane layer applied to a roof to provide it with more protection against the elements and seasonal weather conditions. Coating a roof is one of several roof maintenance services that professional roofers offer to extend the lifetime of a building’s roof. Applying the material often involves repairing weak or broken areas before coating the entire roof in a solid layer of the material the client chooses.

There are several coating materials an individual can decide to purchase for their building’s roof, so it’s a good idea to explore coating types and learn about the differences between the materials before choosing one.

Roof Coating Types

There are a few main types of roof coating to choose from, and each type has its strengths.

  • Silicone Roof Coating: This coating type is often used in areas that get a good deal of sun and rain, as it does well against UV rays and pooling water on lower pitched roofs. In addition, silicone or Gaco roof coating usually requires less material to complete a thick layer due to its high-solids volume.
  • Acrylic Roof Coating: Acrylic is a plastic coating type that’s quite popular because of how durable it is, despite being relatively inexpensive (unless you’re purchasing Polyurethane coating, which is a little more costly than standard acrylic). Acrylic’s reflective surface is a good option for areas that get a lot of sunlight, and this coating type is also resistant to dirt and mildew.
  • Elastomeric Roof Coating: Elastomeric coatings, like Butyl, is a strong material that’s both highly reflective and low in permeability. This rubbery solvent is a favorite among commercial roof coatings, but it tends to be more expensive due to its low solid volume.
  • Asphalt Emulsion Coating: Asphalt is one of the most common roof coating materials on the market. Because it’s affordable and easy to work with, it’s a staple material for homes and businesses that need extra roof protection. Asphalt can be used as a base for other coating types, but because it is water-based, it is more susceptible to cold weather.

What’s the Difference Between Coating Types?

Not all roof coatings are created equal, and different materials are more suitable for certain locations and roof types. For example, metal roof coating will benefit more from a silicone or acrylic material over an asphalt emulsion material.

Additionally, there are other factors to consider when choosing a roof coating material, which we’ll cover briefly.


Of course, strength is a crucial component of roof coating preference. Measured in psi (pounds per square inch), a material’s strength refers to the pressure it can handle before it cracks.

Most robust material: Polyurethane or Silicone

Moisture Resistance

A coating’s permeability is the material’s ability to allow liquid or gas to pass through it. At a glance, the coating type’s permeability does not necessarily mean it’s either good or bad at resisting moisture. Permeability and moisture resistance depends significantly on the material itself. Silicone has a low permeability rating, which means it’s resistant to moisture. Yet, the high permeability rating of acrylic shouldn’t suggest the opposite. Instead, it means that acrylic is simply more breathable than silicone.

Highest moisture resistance material: Silicone or Elastomeric

Solid Volume

Solid volume is how much of the coating material will remain on the roof once the product dries. Coatings with high solid volumes will require less material to coat a roof, while those with low volumes will take more material because of shrinkage as the material dries.

Highest solid volume material: Silicone


Roof coatings with high emissivity values can release heat that the surface absorbs more efficiently than coatings with low emissivity values. Emissivity is measured as a decimal point between 0 and 1, and a .65 is considered to be a decent value.

Highest emissivity material: Acrylic, Silicone, or Elastomeric


Reflectivity is a material’s ability to reflect light. A high reflectivity percentage means that the material reflects a significant amount of light and thus reduces the heat that’s otherwise gained from the sun’s rays beating down on the roof. Light-colored materials are generally great reflectors.

Highest reflectivity material: Acrylic or Silicone


Elongation refers to how stretchable a coating material is. The higher the elongation rating, the more enduring the coating will be when it comes to the regular expansion and contraction of the roof. Materials with low elongation values may thin, crack, or peel if the roof expands and contracts.

Highest elongation material: Elastomeric

Roof Coating Cost

Cost is a big part of the decision-making process, and pricing that fits within an individual’s budget is often the defining factor when it comes to coating materials.

Acrylic and asphalt coating are the most affordable coating types, followed by polyurethane. Silicone and Elastomeric coating are more costly coating options. Still, silicone has a higher solid volume, meaning less of the product will be needed to complete a solid layer.

Does It Take a Professional to Be Able to Point Out a Bad Roof Installation

Often, a homeowner doesn’t know what to expect when they have a new roof installed. When the finished project doesn’t look right, it can leave the individual second-guessing their own impressions.

While a roofing professional should ultimately determine whether a roofing installation has been done correctly, it doesn’t always take a keen eye to discover a problem.

Read on to learn what to look for when examining your roof installation, so you can determine when to call a professional roofing company.

Do You Suspect A Problem?

In some cases, it doesn’t take a professional to point out a bad roof installation. If you suspect there’s something wrong with your roof at a glance, there’s a good chance you’re right to be concerned. When a roof installation looks questionable even to an untrained eye, there’s likely a serious problem with the structure that needs to be addressed.

Look for the following signs of a bad roof installation to confirm your suspicions.

Obvious Signs of A Bad Roof Installation

Some of the most glaring issues can be impossible to miss, and if you notice any one of them, it’s probably time to consult with a professional roofer.

  • Lackluster or absent roof evaluation performed before roofing work started
  • The roof does not appear uniform
  • Dips on the roof that collect water, snow, or debris
  • Stains on your ceiling
  • Roof damage has become visible
  • Roof leaks

Less Noticeable Signs of A Bad Roof Installation

Some signs of a bad roof installation are a little more difficult to notice, but you might spot some of these problems upon inspection.

  • Poor nailing technique: Over-driven or under-driven nails, using nails that rust, or spacing nails improperly
  • No drip edge: A drip edge is metal flashing installed at the edge of your roof. Without this component, water can get behind your gutters and rot the fundamental layers of the roof.
  • Missing or damaged shingles

Should You Call A Professional Roofer?

If you suspect something is wrong with your roof, it can’t hurt to consult with a professional roofer. Representatives from a reputable roofing company are trained to notice obvious and relatively well-hidden installation issues. By reaching out to a local roofer, you can have the peace of mind to know whether your roof needs repairs or replacement.

Additionally, in some situations, a professional roofer can help you determine your next steps if they discover that the previous roofer performed the installation poorly. A professional roofer can often assist homeowners with collecting evidence of poor roofing installations so that the homeowner can present the information to the necessary parties.

If you suspect that your home has undergone a bad roof installation, or you’d simply like a second opinion, reach out to Roof Evolution. Our roofing professionals can evaluate the integrity of your roof and help you plan your next steps if repairs are needed.

How to Choose the Best Shingles for My Roof

How to Choose the Best Shingles for My Roof

How to Choose the Best Shingles for My Roof

Choosing a material for a new roof or roof replacement involves significant research. Every material has its pros and cons, so you’ll want to determine the shingle type that best suits your needs.

If you’re trying to choose the ideal shingles for your roof, consider the factors listed below to effectively narrow down your choices and make the roof replacement process less stressful. 

Shingle Material

Roofing shingles come in many different materials, so if you want to choose the best shingles for your roof replacement, take a look at the shingle types common in your area. These may include (but are not limited to):

  • Steel or aluminum
  • Asphalt
  • Wood
  • Solar
  • Clay or slate
  • Concrete


The price of roofing material is a crucial factor for most homeowners. While the cost of shingles should not be your only consideration, it’s understandable to want a high-quality product even if you have a budget in mind. The more affordable shingle materials include asphalt, some metal types, and clay.

The more expensive roof materials include certain types of wood, solar shingles, and slate. However, while these materials may have a higher upfront cost, they can be cost-saving in the long run when it comes to durability and energy efficiency.


Certain roof materials are more appropriate than others, depending on where you live. Consider the weather in your area throughout the year. The summer heat, the winter cold, and the amount of rain and hail your locality experiences should factor into the material you choose when planning your roofing replacement.

Asphalt and metal shingles are both common roofing materials throughout Colorado, but concrete, slate, wood, and clay are also worth considering.

The Lifetime of Your Shingles

Very few homeowners want to invest in new roofing shingles that they will have to replace in only a few years. As such, it’s essential to ensure that you’re buying high-quality materials and having them installed by a reputable roofing company.

Most roofing types last for at least 20 years, but some can last up to 70 years before they need replacing. To be sure you’re buying the best type of roofing for your home, consider the estimated lifetime, price, and style of your options.

Finally, to help you choose the optimal roofing shingles for your home, you may want to consult a professional roofing company for advice. 

If you reside in or around the Englewood, CO area, reach out to Roof Evolution for assistance in choosing new shingles and having them professionally installed. We have more than two decades of experience serving the Englewood area and are happy to apply our expertise to your roofing needs.

5 Reasons Why Poor Ventilation Can Rot Your Roof

5 Reasons Why Poor Ventilation Can Rot Your Roof

5 Reasons Why Poor Ventilation Can Rot Your Roof

The importance of a quality roofing ventilation system isn’t always apparent. As such, when an issue occurs with a roof’s ventilation system, homeowners may put off repairs, assuming they’re not urgent.

However, a roof’s ventilation system is in place for a reason, and ensuring that the vents are working properly helps extend the roof’s life.

Let’s explore the ways that poor ventilation can lead to roof rot.

#1- Heat Build-up

Because attics are not climate-controlled, adequate ventilation is needed to keep the area from becoming too warm. Poor roofing ventilation can cause attic spaces to become increasingly hot, up to 150 degrees in some locations. This extreme heat can dry out, weaken, and damage roofing material if left unchecked.

#2- Mold Production

In addition to building up heat, poor ventilation can make attic spaces more humid than they should be. Warmth and humidity create an ideal environment for mold production, and with it comes new problems. Not only can mold be dangerous to human health, but it can also encourage roof rot.

#3- Condensation

When the temperature inside an attic contrasts significantly with the temperature outside, it may increase condensation development. A moist attic encourages mold growth, which can cause roofing material to warp and can eventually lead to further moisture-related damage to other parts of the home (like the walls and foundation).

#4- Shingle Deterioration

Even on a mild day, shingles are exposed to significant heat. A decent ventilation system helps the shingles regulate some of that daytime temperature. The absence of roofing vents can put additional strain on shingles. Poor roofing ventilation can make shingles expand, contract, and even break under heat stress.

#5- Structural Damage and Sagging

Heat build-up, mold, and condensation will damage roofing materials over time. The damages often involve warping the wood, which weakens its structural integrity. When roofing beams and other pieces of material sustain damage, they may bow out or sag in certain areas.

These shape changes can allow snow or rainwater to nestle in certain areas of the roof rather than rolling off. As a result, the roof sags and may eventually leak or fall apart.

A hot, stuffy attic isn’t just inconvenient and unpleasant; it’s a serious problem when it comes to the integrity of your roof. If you notice excessive heat, mold, moisture, or sagging around your home’s roof, it’s best to reach out to a roofing professional who can further assess the damage.

Roof Evolution is here to help with your roof ventilation needs. If you reside in or around the Englewood, CO area, don’t hesitate to schedule a free consultation.

Replacing Your Roof During Winter In Colorado

Learn More About Replacing Your Roof During Winter In Colorado

You may be considering repairing or completely replacing your roof right now, either because it suffered extensive damage after a weather event, have lost several tiles, or your roof is so old that it already affects your home’s heating system, but you are feeling doubtful about getting this work done in consideration of that is winter. Despite what people usually believe, there is not only possible to replace your roof during winter in Colorado, but there are several benefits to doing so. 

First of all, you should analyze if your roof does need replacing at this moment or not. For that purpose, you may take in mind some signs that could indicate it’s time for a new roof:

  • Snow is leaking in the attic or on the ceilings inside your home.
  • Damaged or missing shingles.
  • Light shining through the roof sheathing (the boards underneath the shingles).
  • Excessive amounts of moss or algae grow on your roof.
  • Sagging or buckling in the middle of the roof 
  • There are large patches where the wood is visible.
  • You notice an increase in your monthly energy bills.
  • Ice dams (insulation problem)
  • Excessive amounts of snow on the roof (more than a foot)

Snow and ice ❄

The snow removal or de-icing of an asphalt surface needs careful attention with extra equipment, done by a trained team, and under supervision while doing this job. Working on a slippery surface could be risky – especially considering how quickly ice/frost buildup occurs even without any additional moisture entering its environment (from rain). Also, it’s key to make sure that surfaces are clean before starting any projects. That will help the contractors and yourself save time and avoid an accident. 

Which type of roof is the best? 

There are a few types of roofs that can be laid in the winter. The most popular options are metal and asphalt shingles. Metal roofs need to be correctly insulated to prevent ice dams from forming. Asphalt shingles need to be heated so the adhesive will adhere to the roofing paper better. If you’re looking for a winter weather-resistant roof, we’d recommend a metal roof (but that can vary due to your house’s needs). Metal roofs are durable and can withstand high winds and heavy snow loads. They also have a longer lifespan than asphalt shingles. 

Also, during the winter, you can choose flat roofs options such as PVC or TPO. These thermoplastic single-ply products replace older and less efficient adhesives with hot-air welded seams. That provides better durability while preventing leaks in harsh conditions like cold weather.

What is the right temperature? 

When the temperature drops below 40° F, it becomes too cold for roof installation. To ensure that your home warranty is valid and reduce the risk of making a mistake during installation, be sure the temperature is between 70-80 Fahrenheit when replacing or installing the roof. 

Note: If the temperature is below 40 degrees Fahrenheit on rubber roofs will freeze if not sealed correctly before installation. 

The best way to keep your shingle looking good and functioning all year round is by using a sealant that bonds with the metal, rather than just lying on top. A thin layer of thermal-initiated blacktop adhesive will attach itself quickly into any gaps or ridges in between tiles ensuring an even surface for years’ worth more snowfall.  

As you can see, replacing your roof during cold weather could be very challenged, and that’s why you need to count on a specialized contractor to do this job successfully, and there is no need to wait until spring or summertime to fix your roof. Remember, preventative maintenance can save money by helping ensure that only necessary work gets done during cold months rather than having extra costs.

Why You Should Keep Your Roof Clean

Why You Should Keep Your Roof Clean

Protect Your Roof System

Your home’s exterior can have just as much personality as the interior. It says a lot about yourself. But, your home’s curb appeal it’s not the only important thing but also keeping your entire roof system in excellent condition, internally and externally.  

Generally, your roof faces common issues such as: 

  • Lifted nails or shingles
  • Debris from nearby trees
  • Clogged gutters
  • Leaking
  • Pooling water
  • Shrinking
  • Cracking
  • Poor maintenance
  • Algae, moss, and lichen growth

Debris on your roof and gutters can cause water to pool, cause leaks, or other problems that could damage the interior living spaces below. This could include the electrical systems, which can lead to fires if not dealt with quickly enough. Also, this can lead to pest infestations, or attract animals such as birds or termites, causing worse damage to your tiles.

How to clean your roof?

Some of the most used methods are the soft wash using chemicals or the pressure wash utilizing highly pressurized water to strip away dirt and grime. But either the way you choose to clean grime and debris off your roof, keep in mind that the cleaning needs to be done thoroughly, including:

– Black stains or GM algae bacterium that can be grown on asphalt roofing by a mixture of trisodium phosphate (TSP), bleach, and water

– Lichen or fungus that has the ability with its roots in moisture absorption as well an adhesive-like quality which helps them stick tightly on any surface they grow onto by scrubbing away at them using soap water followed up by cold weather exposure

– Mold that is considered the most dangerous and weakens the structure of your roof quickly. To remove it, you can rinse your roof with 1 part bleach or sodium hypochlorite solution every 60 minutes while letting it sit for up twelve hours before repeating the process. Or you can get a commercial cleaning solution in the market. (Be sure it’s the right one). 

To avoid any of the above cases after cleaning, we recommended:

  • Repeat the cleaning process every year and half 
  • Trim back overhanging tree branches and wash them with a chemical cleaner 
  • Install algae-resistant shingle manufacturers that have mixing copper granules.
  • Clean your gutters habitually. 
  • And schedule a bi-annual inspection to identify any problems before they become too costly or time-consuming, and can help prevent leaks in the future!

When cleaning is not enough, perhaps it’s because your roof is old, or you are missing shingles so, here is when you need to change the whole rooftop.  

Your roof is the crown jewel of your home, so it must be in good condition. Keep all weather elements at bay and protect you from what lies above. Contact us now for a free estimate!
