Pros and Cons of Liquid Butyl Rubber Roofing

Liquid rubber roof coatings are popular for several applications. They’re durable and generally easy to work with, and they come in several styles so that there’s something for just about every need. When it comes to choosing the right materials, it can be helpful to take the time to get to know all the options a little better. To help with that, here are some things to consider when thinking about using liquid butyl rubber roofing.

Usually, a liquid butyl rubber roof is fairly simple to install. Some people can do it in an afternoon or a weekend on their own, while others might enlist the help of professionals. Liquid roofing is great because it’s easy to work with and goes on much like paint. Instead of having to lay sheets and protective membranes and then seal all the seams, liquid offers a much simpler application.

Liquid roofing is also durable and flexible, which means it can hold up to a lot more than the average roofing material. Plus, it’s lightweight, so it doesn’t add a lot of pressure to the ceiling or roof structure like some materials would. It helps prevent moisture from seeping into the roof and can even help with ponding water resistance so that no water gets in, even if there’s a puddle on the roof for a week.

And of course, you can’t forget how butyl coatings reflect as many as 80-90% of the UV rays from the sun, so they are more eco-friendly and help keep heat from building up in and on the roof.

There aren’t as many disadvantages to consider with this type of product, but there are a couple of things to keep in mind. Liquid butyl rubber roofing is harder to spray on, but that’s where professionals come in handy. If you choose a spray-on roofing product, be sure to mind cleaning the equipment well. The only other real disadvantage is that there’s a lack of color stability but usually people installing these roofs aren’t looking for a custom color or finish.

All in all, liquid butyl rubber roofing is a great product with many benefits and useful applications. Make sure that you explore all the options that you have for roofing to get the best finish, no matter what type of rubber roofing that is. You’ll have a durable roof that will last for up to 20 years or more, and that’s just the start.

Properly applied roof coating systems can breathe new life into a mature low slope roofing system, brightening its appearance, enhancing its energy efficiency and delaying for years the day when it will have to be recovered or replaced. The operative phrase in that sentence is “properly applied.” Coating a roof is more than simply spraying, rolling or brushing on the finish coats. What will determine the quality and longevity of the installation is the time and attention paid to preparing the roof before it is coated. Too often, contractors take shortcuts on, or skip altogether, this essential first step. The result? Problems with the existing roofing system remain problematic, the coating system does not properly adhere to the substrate, and a roof restoration that could have lasted 10 or 20 years fails in as little as two or three. Completing three simple steps before applying the coating system will prevent this outcome and help ensure the newly coated roof delivers the expected years of hassle-free, watertight performance. First, repair any existing damage. Second, perform the roof surface.

WHY PREPARATION IS ESSENTIAL

It is understandable that contractors new to coating application and untrained in the process could overlook the preparation step. Their experience is in working with roll-good roofing, where preparation is a step that can be overlooked because the existing roof will be recovered or replaced with new TPO, EPDM, PVC or modified bitumen. The new system will cover up any leaks or other damage and will be designed to address ponding water or other issues that plagued the existing roof. When coating, however, the contractor is not installing a new roof, but is restoring or maintaining the performance of the existing roofing system. Roof coatings are not “miracles in a bucket.” They will not fix leaks, reseal open seams, repair deteriorated flashings or loose terminations, prevent ponding water, address damaged or saturated insulation or substrates, or correct other problems with the underlying roofing system. Those issues will still exist after the coating has been applied and may prevent the coating from properly adhering to the roof. And if a coating is slapped on top of a grimy, greasy, debris-ridden roof, it almost certainly will soon begin to flake, blister or peel off.

REPAIR EXISTING ROOF DAMAGE

Step one is to assess the existing roofing system and make necessary repairs, carefully following the relevant guidelines from the manufacturer of the original roofing system and the National Roofing Contractors Association (NRCA). In general, the existing roof assembly must be structurally sound, watertight and free of shrinkage, buckling, unacceptable ponding conditions, encapsulated moisture, open seams, open or damaged flashings, loose terminations and other serious defects. Coatings also should not be applied if the substrate or insulation is saturated with water. The good news is that, with some simple repairs, even a roofing system with significant damage can be made a viable candidate for coating. The following examples illustrate some Common scenarios. Problem: A roof has an area that is susceptible to ponding water. Solution: Fill the ponding area with slope-correcting materials or correct the slope with a cricket or tapered insulation and cover it with new materials similar to those of the existing roof. It may be necessary to install drains to allow positive drainage. Problem: A 2-square area of a 100-square TPO membrane is damaged. Solution: Cut out the problem area and replace it with like material, or heat weld two squares of new TPO over the existing membrane to recover the damaged area. Problem: There is an active leak in one corner of a roofing system. Solution: Cut into the damaged area. Remove and replace the saturated insulation if necessary. Fold the membrane back in place and flash around where the cut was made. structurally sound, apply primer to encapsulate the existing rust and inhibit the creation of additional rust. If any panels are so corroded that they are no longer structurally sound, replace them; the remaining panels can be left in place. Problem: The seam welds on a TPO or PVC roofing system are pulled or loose. Solution: Several options are available. (1) Reheat the seams to weld them back in place. (2) Put a target patch made of new membrane over the seams. (3) Reseal the seams with flashing compound.

PERFORM AN ADHESION TEST

A coating’s performance depends on how well it adheres to the substrate. An adhesion test should, therefore, be performed to ensure that the coating is compatible with the substrate and that encapsulated moisture or other underlying issues that could impact adhesion have been properly addressed. Instructions from the coating manufacturer should be followed, and those instructions may vary based on the warranty desired but following are general guidelines. Choose a 2-foot-by-2-foot area of the roof as the test site. Clean the area using a rag or bristle brush and a solvent that will flash off quickly without leaving a soapy residue behind, such as acetone, xylene or mineral spirits. Coat a 1-foot-by-1-foot section of the test area, replicating what the finished system will be. If the roof will be primed, prime the test area. Apply primer and finish coats at the same application rate that will be used to coat the entire roof. Embed several strips of Tietex or other polyester-reinforced fabric, each roughly 1 inch wide and 12 inches long, into the coating, leaving Problem: A metal roof has rusted. a 4-inch-long pull tab outside of the wet area. Brush the fabric to embed it into the coating. Apply a second coat of finish coat to ensure the fabric is fully saturated. Allow the coating to cure fully, at least 4 to 5 days. Test the adhesion using a fish scale. For each test strip, tie a knot in the loose, uncoated end of the fabric strip Hook the fish scale into the knot. Using the fishhook, pull the fabric straight up. The ideal “pull strength” is at least 4 pounds per linear inch (pli) of fabric, or at least 4 pli over a sound and dry substrate. The test is a “pass” if the fabric separates from the coating, leaving the coating still adhered to the roof membrane. The test is a ““failure”” if the coating separates completely from the roof surface. All adhesion tests should be documented with photos of the cleaned substrate, the wet coating and embedded fabric, and the face or display of the fish scale showing the resistance observed in the test.

CLEAN THOROUGHLY

Roof surfaces must be thoroughly cleaned prior to coating. Over years of constant exposure to the elements, dirt, oils, bird droppings and other debris collect on a roof’s surface. If not removed prior to coating, they interfere with the coating’s ability to adhere to the substrate. Rather than sticking to the roof, the coating fuses to the grime and, unsurprisingly, may soon begin to peel off. The best results will be achieved by applying the manufacturer’s recommended roof wash or cleaner and then power washing. While power washing alone will get the roof clean, the roof wash loosens the dirt, grease and other debris, allowing it to be removed with less-aggressive power washing. We highly suggest using roof protect.  This cleaner actually emulsifies the contaminates on the roof and also has a built in mildewcide.  This gentler approach significantly reduces the risk of damaging the roofing membrane while cleaning. Years of being subjected to sun, rain, snow, ice, heat and cold can weaken the membrane, and a blast with a heavy-duty gas-powered rig generating 2,800– 4,000 psi of pressure can easily blow a hole in it. A smaller rig generating only 1,800–2,500 psi of pressure will remove the sediment in most cases. Using a walk-behind power washer, rather than a common extension wand-type setup, also helps ensure adequate cleaning pressure at the surface of the substrate without over-exerting effort on the behalf of the worker. Rinse water should be directed toward drains and scuppers to ensure the detergent and debris are completely removed. If the rinse water is simply allowed to evaporate, what can be left behind instead of a clean, coating-ready surface is a caked-on mixture of gunk and detergent residue. EPDM roofs should be power washed twice — once with ROOF PROTECT and once with clean water. The carbon black that gives EPDM its black color breaks down over time, and that dust must be removed to ensure proper adhesion of the coating. The test of whether the carbon dust has been completely removed is a quick wipe of hand across the surface; a clean hand means a clean roof. Granulated modified bitumen roofs should be swept with a dry broom or power broom prior to power washing to remove loose granules that could clog the roof drains. Make any necessary repairs.  Perform an adhesion test. Thoroughly clean the roof surface. Completing these three simple steps before coating will help ensure a successful roof restoration that extends the roofing system’s life, adding years of weathertight, hassle-free performance

What is a Liquid Butyl Rubber Roofing System?

There are several roofing options out there today, including a variety of materials and even roofing “systems” or designs that include a full application process from start to finish rather than just a material and installation (as with shingles, for example).

Butyl is a synthetic copolymer, which basically means it’s a blend of different rubbers that create a structurally sound product that is uniquely able to be applied as a liquid. It then cures to harden but remains flexible, which makes it an ideal roofing system for several different applications.

In the past, only rolled or sheeted rubber roofing was available. Not only were these materials more expensive, but they were heavier and they required more installation. They also left seams that needed to be sealed to prevent leaks. With liquid butyl rubber, that’s no longer an issue. This material can reach places that sheeting could never have even thought about covering and they can be applied on all kinds of roofs, including:

  • Fiberglass
  • BUR
  • Modified bitumen
  • Concrete
  • Metal
  • And more

This roofing material is gaining popularity for all of its conveniences and its ease of use. There are several products on the market today and it will be up to you to choose the ones that best suit your needs.

EPDM Butyl Rubber Coatings and Rubber Roof Repairs

Do you have damage to your roof? Depending on the type of roofing system you have, you might be able to use EPDM Butyl Rubber Coatings as a means to repair it. These coatings provide some great advantages and could be used to cover your entire roof and provide it with a substantial amount of protection.

You’ll find that EPDM Butyl Rubber Coatings are a rubber option that can be used for a range of purposes including RV roofs, commercial roofs, and even flat or slightly sloped residential properties. Let’s get a closer look at what the material is and then how it can be used for repairs.

What Is EPDM?

EPDM is made when ethylene and propylene are combined with a diene monomer attached. This synthetic elastomer is resistant to oxidation and UV rays, and it works as an excellent barrier to moisture. It can tolerate temperatures that are extremely low or high, which means it can be used with great effect in any geographic environment. EPDM rubber has been used for a host of purposes over the years, not just roofing.

For roofs, there are several options. Often, there are large sheets that can be attached to the roof as part of the roofing system. To provide further protection, EPDM Butyl Rubber Coatings for the rubber roof are often added.

If you have a roof that already has a liquid rubber coating, or if you have a roof with EPDM sheets, you can often make spot repairs on areas that have issues. If you have a different type of roof, you may need to add a full coat of the EPDM Butyl Rubber Coatings and rubber to the entire roof. It all depends on the type of roof you have for your home or RV and the damage it has.

Take the time to find the areas that need to be repaired with a visual inspection. You can do this, or you could hire someone to inspect and repair the roof if you prefer.

Clean the Roof

Regardless of the type of roof, the first thing you need to do is clean it. You will want to sweep away all of the debris that might have accumulated on the roof. This could include leaves, branches, dirt, etc. You will then want to clean the roof using water to get up and as much dirt as possible that has become stuck to it.

Repair Any Damage

If there is any major damage, it should be fixed before using the coating for the final repairs. For example, if you have a hole in the roof, which will need to be repaired before you can put on the EPDM Butyl Rubber Coatings. Once any large damage has been repaired, you can then figure out how much of the material you need to patch the areas where there are cracks and holes.

If you are going to be doing the entire roof, you should make sure that you buy enough to cover your whole roof. If you are only going to be doing spot repairs on your roof, you will not need to have as much.

Carefully Apply the Coating

The EPDM Butyl Rubber Coatings are rubber that’s been liquified, which means it can go on similarly to paint. You can even use brushes and rollers. If you only have a small area to do, then a brush might be all that you need. If you have a larger space to cover, using rollers will be a better option.

The coating tends to dry and cure quickly, so you can ensure your property is waterproof almost as soon as you apply the liquid rubber.

Take Good Care of Your Roof and Consider an EPDM Coatings Roof System

You want your EPDM coatings and roof system to last for as long as possible. These systems are durable, which is one of the reasons they are so popular. However, this doesn’t mean that once it has been installed that you can simply forget about it. You still need to make sure that it is cared for properly.

It’s easy to do, but you don’t want to be lax in your maintenance or else you might not notice small issues that can grow into large problems. When you take good care of the roof, it can last for decades. Here’s how to do it.

Inspect Your Roof

First, you should get onto the roof and inspect it at least twice a year. This should be at the beginning of spring and in the autumn. Physically get onto the roof and look for any potential signs of damage. An EPDM coatings roof system tends to be durable, and you won’t likely see any issues with cracks or split seams.

However, something might have hit the roof to cause a tear or a hole. If that’s the case, you will want to reapply coating to the area after you have cleaned and patched it. Look for any sort of damage that is on the roof, as well as areas of standing water, or where it appears water may have ponded before drying.

Even though the coatings are good at handling ponding water, pay attention to these areas to see if there are any issues.

Check from the Inside

Remember to check from the inside, as well. You might not notice a small hole or two from the roof, but if you look from underneath, you might see water damage on the ceiling, beams, walls, etc. If there is damage, it means you have a leak you’ll need to find and repair.

Keep the Roof Clean

During your roof inspections, you should be cleaning your roof off. Sweeping the roof is typically all that’s needed. It will remove leaves, twigs, and other debris. Remove the debris and then clean the roof coating with a professional cleaner. This can help to keep it looking good for longer.

Don’t Ignore the Little Problems

When you find little problems with your roof, don’t make the mistake of ignoring them. These small holes or leaks will not magically heal themselves. They will only get worse the longer they are allowed to exist. You should instead endeavor to repair them as quickly as possible. In some cases, this is as simple as patching an area and recoating it. Other times, you might need to have help from a roofing contractor.

Why Will an EPDM Coatings Roof System Help?

These systems are a great solution for many types of roofs. They are long-lasting and strong enough to withstand hail, rain, debris, and a host of other issues. The coatings are an affordable option, they are easy to install, and even repairs tend to be easy. There’s a lot to love about these roof coatings.

Get the Right Coatings Today

If you are interested in EPDM coatings and a roof system, it’s time to figure out what options will be best for your needs. Do you need to have a lot of the liquid coating to go over a large commercial property? Do you only need a small amount for the top of your RV? Figure out what you need and then get the coating and the tools needed for installation. You can install them yourself or hire someone to do it for you.
