Durability of Liquid Roof Coatings

--> -->

Liquid Roof is a liquid elastometric copolymer rubber coating that has excellent elongation, tensile strength, UV resistance and durability. Cures to a hard white or light gray rubber heat reflecting coating!
The material factors that influence durability are complex and related to the chemical composition of the liquid constituents, the thickness of the system as well as the type and density of the reinforcement. Central to the long-term success of liquid-applied waterproofing systems is preparation of the substrate and achieving the required membrane thickness.
Typically, manufacturers only guarantee their products when applied by approved and trained installers. This is not surprising as standards of application by squeegee, roller, brush or spray are very demanding; layers are measured to tenths of a millimetre and avoidance of air holes is essential. The weather conditions in which the liquid is laid are critical as are the times between application of coats.

Other key durability issues include:

* Ensuring the substrate construction and condition is free from material which may impair the bond, create thin spots or penetrations in the coating.
* Provision for moisture removal of damp substrates.
* Ensuring there are no point loads on the roof.
* Specifying a system suited to the expected traffic load.
* Appropriate detailing at edges, verges, upstands, outlets, movement joints and day joints.


Liquid-applied coating that forms the waterproofing layer of an inverted roof should not require replacement during the life of the building, provided it is fully protected from ultra-violet radiation and extreme temperature variations by a loading layer above it.

By increasing the longevity of roof materials by using cool coatings, organizations can avoid a substantial amount of roofing waste. There are an estimated 11 million tons of asphalt roofing waste going into landfills every year. Using liquid roof coatings can greatly increase the life of existing roof materials (particularly roof coatings) and reduce the amount of torn-off roofing waste going into landfills. The roofing waste that remains can be recycled into road mixes using existing processes already operating.

During a home inspection, roof leaks are typically discovered by my direct observations and then confirmed by utilizing moisture meters on the sheathing below. But if I detect a moist area and the roof sheathing is not visible from below (such as a finished cathedral ceiling or a ceiling below a living area) the exact area of the leak can not be determined. Most homeowners have the misconception that moisture stains are caused from leaks that are directly above a wet area. It’s just not true in most situations. On gable roofs, some leaks occur at the ridge line area and cling to the rafters for quite a distance until it finally drips onto the ceiling below. In order for anyone to locate the exact area of the leak, the damaged ceiling must first be removed. This removal is necessary in order to “visualize” the exact intrusion point at the underside of the roof sheathing. Now before any of the ceilings can be removed, all the furniture must be removed from below the affected area. Then the floor must be protected from the falling debris and possibly requiring a scaffold system. All of this can cost hundreds and even thousands of dollars! Infrared Thermography is an invaluable non-destructive and non-contact tool that can detect and pinpoint hidden roof leaks without even damaging the interior or exterior surfaces. Then once I pinpoint the problem area, minimum surface areas can be removed in order to make the necessary repairs.

I prefer to perform all exterior roof inspections in the early evening hours. In order to perform the infrared inspection correctly, I require solar heating of a hot sunny day to heat up the roof surface. Then in the early evening (after the sun goes down), the roof starts to cool allowing my infrared camera to be able to detect obvious thermal differences if there are any moisture intrusions within the roof surface. Thermal properties of water are very unique (high thermal capacity), allowing water to be thermally observed on the surface and on the underside of roofing materials. If water is actively seeping into the cavity of a roof surface, the dry roof insulation will cool much faster than the soggy wet roof insulation, making it possible for me to observe the thermal differences.

Liquid Roof

Liquid Roof is a liquid elastometric rubber coating that has excellent elongation, tensile strength, UV resistance and durability. Liquid roof is a true EPDM rubber and is available in liquid form only. In fact it is the liquid version of single ply EPDM membrane, one can say, Liquid EPDM. It can be employed for both repairing and replacing the EPDM or sheet rubber roof. Its features such as waterproofing and easy application over all roofing materials, UV and ozone resistance, elasticity and long term flexibility, capability to withstand large temperature range i.e. from -62 degrees F to 300 degrees F without cracking or deteriorating, make it very different from other roof coatings. It is also a one-coat application product, ultimately saving both time and money.

Liquid Roof and liquid rubber are super-strong and waterproof, and is able to survive tremendous temperatures of warmth and chilly. The liquid form makes it possible to apply EPDM rubber to many materials regardless of their shape. It cures by chemical reaction at ambient (ordinary) temperatures to form a flexible rubber membrane. A pre-measured catalyst is added to the rubber compound before application. The true Liquid EPDM rubber available in the market is Liquid Roof. The advantages that this liquid rubber coating offers are countless. It is waterproof, has high compatibility with almost all types of surfaces, very flexible and elastic and can withstand a large temperature range from -62 degrees F to 300 degrees F without cracking.

Liquid roof ideally can be used for many types of roof repair. One of the most important Liquid Roof Repair applications is RV Roof Repair. Liquid roof sticks to the entire types of facades- canvas, plywood, suds, cement, mass rubber, customized roofing, additional roof coverings, strengthen, timber, top tiles, genuine tiles, solid, and many more. It is the most cost effective and efficient product for solving RV Roof Leaks Repair problem as it does not chalk, shrink, crack, peak and flake.

Roof Sealers

-->

High-strength elastic roofing and sealing material consisting of at least one bonded fabric layer of organic material, optionally at least one further bonded fabric or bonded-fabric material layer of inorganic material, and a coating of bitumen on both sides, where the bonded fabric layer(s) is (are) impregnated with the bitumen, and where the bonded fabric of organic material has a certain area weight and a certain residual deformation after previous elongation. The bitumen coating optionally can be made elastic by the addition of modifiers with sufficiently low glass conversion points.

The sealant can be used for installation and maintenance of a roof made of shaped boarding or roof tile:

• in places of isolation joints between open-ended exit points and roof sheets;
• under ridgy planks and joints of a tent shape roof;
• under a snow shield on a roof;
• when installing the furring;
• at lap seams;
• at trough joints;
• at a joint of a trough and a drainpipe;
• at a trough end;

Ensure roof tiles are clean and dry prior to application of roof sealer. Apply roof sealer with a sprayer unit, brush or roller. The first application must be applied to the surface and allowed to dry past tacky prior to applying the second coat. Avoid application in strong, direct sunlight - do not apply if rain is likely within 4 hours of application.

Roof Sealers are bright white, reflective, elastomeric roofing solutions for roofs that are not yet ready to be torn off and are capable of being restored back to their original quality. EPDM, Modified Bitumen, Metal Roofs, Single-Ply, Polyurethane Foam, Smooth Built Up, or even Gravel Built-Up, we have a roof coatings that can repair and restore your roof. Our roof coatings can even repair metal roofs to good as new condition.

The Importance Of Roof Coatings

EPDM rubber is a very flexible and long-lasting material that has a huge range of different purposes and applications. EPDM stands for Ethylene Propylene Diene M, in which the M refers to a class of rubbers that contain a saturated chain of the polymethylene type. What that means in simple terms is that EPDM rubber has fantastic heat, ozone, and weather resistance. It is also a great electrical insulator.
EPDM sheeting is often used as a liner for back yard water ponds and other man-made water features. The rubber does not leach chemicals, and so would not harm any fish living in these ponds. EPDM roofing material is one of the most common applications of this rubber product, although it can be used in garden hoses, washers, belts, electrical insulation, seals and speaker cone surrounds.
EPDM rubber is also often the main substance used in the weather seals of vehicles, such as door seals, window seals, and hood seals. This is due to the great weatherproof properties of this type of rubber.
The importance of roof coatings can definitely not be ignored. Consequently the awareness of different type roof coatings among the roofing contractors and the building residents is very necessary. Therefore get yourself well aware of what type of coating you need and the type of roof you have so that you are able to apply the roof coating which is best for your roof.

RV Trends And Roof Leaks

We love to see how other people live, especially away from huge metropolitan areas - and where there are few if any motels, convention centers, and restaurants. This world has vast reaches of beautiful farmland, spectacular mountains, forests, grasslands, lakes, rivers, etc.... We can easily refuse to stay in places that have rules we think are idiotic, and if we are assigned to a site with an obnoxious neighbor, it is not the end of the happy hour… we can move.

If you have kids, you probably take an annual family vacation. However, between expensive hotel rooms, dining out and pricey amusement parks, family vacations can cost a small fortune. One solution to high priced vacations is investing in an rubber coating. Once thought to be vacation travel mode of senior citizens, more and more families with young children are purchasing RV's or tow-behind campers, instead of tickets to Disney. Even with gas prices rocketing, camping with an RV is still cheaper than staying at many resorts and hotels.

On an RV/camping trip, families are not faced with the interruptions of routine home life, yet they have the comforts of home. RV'ing families are able to enjoy each other's company and kids are free to be themselves, without their own set of distractions like piano lessons, soccer practice or homework. RV'ing means every weekend can be a mini-vacation, allowing quick getaways with minimal preparation and planning.

Many parents also supplement their children's learning during their RV travels, and if it's fun, the children won't object. The Campfire Canvass found that 43% of families cite visiting an historic location for educational purposes. Science and nature centers, zoos and museums were also frequently mentioned.

There are numerous benefits of RV camping. Prices of campgrounds are far less than that of most hotels. You can stay a month at a campground for what you would pay for a weekend at some hotels. In addition, there are hundreds of national parks and campgrounds to choose from all across the United States. Some parks have RV restrictions, but many, including, Yosemite, Yellowstone and the White Mountains National Forest in New Hampshire, all have RV accommodations.

A Complete Solution For Roof Leaks

Most metal roofs are made from sheets, held into place by sheet metal screws. These screws should be sealed annually in order to help prevent leakages from these points. The roof of your mobile home and sometimes the body will flex and move while the unit is being transported, and this can cause cracks and distortions, leading to leaks. Seal the sheet metal screws with a plastic or flexible rubber coating and be sure to repeat this job every year.

Most mobile home roofs make use of vinyl strips, to waterproof the screws in the roof. Be warned that these vinyl strips do not last forever and will need replacing after a few years. Eventually, they will come unstuck and fall from their retaining grooves. You can buy replacement vinyl strips at most mobile home camp sites, as well as many garages and dealerships. Leaks from these screws can be almost undetectable and so it’s advisable to replace all of the strips on a roof completely after 5 years, even if they look fine.

Smaller sized holes can be fixed more easily, using a sticky aluminum tape, for example Peel N Seal repairing tape. Simply clear all debris away from the hole, clean the surface where you are going to stick the tape, and finally seal the hole, making sure the tape is stuck down very firmly and there are no gaps visible.

Consider Liquid Roof for your roofing needs

Anyone who has ever had to undergo roof repairs knows how stressful that can be. Normally, it involves calling in professionals and having them use bulky materials for repairs that only add extra weight to your roof. Liquid Roof coatings can be applied by almost anyone and goes on in one smooth and easy coat so your roof is not bearing any excess weight.

The flexibility of liquid roof allows it to be applied to almost any type of roof, from commercial and residential to RV’s, trailers and boats. It can be quickly and easily molded to fit any surface and within hours it will cure to form a watertight seal that can endure ponding water year round.

Not only will liquid roof negate the need for professional repairs, because it can be applied in one coat, it also helps you to avoid the cost of applying multiple layers or using a primer. Again, this cuts down the cost of repairing roof leaks considerably. And the unique composition of liquid roof is not only watertight, but will reduce both rain noise and heat build-up to keep you cooler and more comfortable.

You want a dependable roof over your head, so don’t waste your time with messy and costly repairs. Use liquid roof and get it done right the first time with a secure seal that will last for years to come. Consider liquid roof for your roofing needs and you won’t be disappointed!

Inspect your roof and minimize your roof leaks problems

If you want to avoid the complication of roof repair, it is necessary to avoid these situations and select those quality products for roof repairing and remodeling purpose like EPDM, EPDM coatings, liquid roof repair, roof repair coating etc. that are best for repairing a roof. If these products like liquid EPDM, Liquid roof, roof coatings etc. at the time of home construction, you will get the best results for your home and can easily minimize the roof repair cost as they provide a long time protection from repairing and roof leaks. The chances of roof leaking problem can also be minimized by setting the roof inspection on the regular basis.

As you find any roof leak in your roof during this inspection, you can easily repair it by yourself. For this purpose, there are many products for this solution, you can apply liquid roof and liquid rubber on your roof for getting release from this problem and can maintain roof leak for a long time period. Roof repairing and remodeling is as easy as you can do it by applying newly designed roof repairing products that are specially designed for the solution of this problem.

RV Roof Leaks and Holes Repairing

Once you have found the source of the leak, you’ll need to patch it up as soon as possible to prevent any more damage. For holes that are bigger than one inch in diameter, it is usually best to use a piece of aluminium sheeting to cover it with. To do this, you need to cut out a piece of the sheeting that is larger than the hole in the roof. Make sure you have plenty of bearing so that you can cover the hole completely. Secure the aluminium sheet to the roof, over the hole, with self taping screws that can be driven straight into the roof. Then, to seal the sheet so it’s watertight, use a putty tape around the edges or some kind of non-hardening putty, making sure there are no gaps left at the edges of the sheet at all.

Smaller sized holes can be fixed more easily, using a sticky aluminium tape, for example Peel N Seal repairing tape. Simply clear all debris away from the hole, clean the surface where you are going to stick the tape, and finally seal the hole, making sure the tape is stuck down very firmly and there are no gaps visible.

If you do not carry out regular maintenance on your mobile home roof, you are running a huge risk. If left too late, then repairing the roof of your mobile home or RV trailer can cost upwards of several thousand dollars and all because you failed to spot a small roof leak in time.

Preventative maintenance can save you an awful lot of money in the long run, it’s easy to perform, and very inexpensive. You don’t even need to have any real skills to do it. Mobile homes need care and attention just as much as our real homes do. If you love your mobile home and take care of it, then your mobile home will take good care of you.

Things to Know before Maintenance of your Metal Roof

Before undertaking any maintenance we recommend that you consult a roofing expert about all the safety precautions you should take before climbing onto the roof.

The following steps should be followed carefully when it comes to carrying out metal roof maintenance work:

1. Do not allow different kinds of metal to be touching one another. When different metals touch, chemical reactions can occur and cause the metal to corrode.
2. Be vigilant and make sure the paintwork is always touched up. This will help to prevent rust.
3. As soon as you spot a hole or an open seam, repair it immediately, do not delay!
4. Smaller holes can be covered with either roofing cement, or else the EternaBond tape that was discussed previously. Large holes need to be patched and soldered into place with the same kind of metal as the roof is made from.
5. Any screws that you use must be of the same kind of metal as the roof.
6. When screwing plates or sheets into place, make sure you always use a washer, and install the screw into a raised area rather than low areas as this can lead to water pooling and eventual leaks.
7. Use only non-corrosive metal flux with steel roofs. For copper roofs, acid flux is best.

These are the tools necessary for carrying out metal roofing repairs:

• Galvanized metal
• Screws of the same type of metal as the roof
• Roof coatings such as PVDF
• A putty knife
• Butyl tape or EternaBond tape
• Roofers caulk
• Wire brush
• Snips

Steps to take when patching a hole:

1. Firstly, clean the area around the hole thoroughly, washing away all dust.
2. Cut a good sized piece of galvanized metal that covers the hole easily. You should have a bearing of 2 or 3 inches over the edge of the hole.
3. Tape the galvanized metal sheet into place with the butyl tape.
4. Screw the sheet into the roof, spacing the screws out every 2-3 inches.
5. Seal the edges of the sheet and around the screws with caulk.
6. Finally, cover the new patch with PVDF roof coating.

Technical Data and Physical Properties of Liquid Rubber

When we talk about the nature of EPDM Liquid Rubber the slow curing and non polar nature of the EPDM Liquid Rubber give it a tremendous and outstanding surface wetting properties. EPDM Liquid Rubber can’t only be used to fill cracks crevices but will produce an even film penetrating even the smallest cracks and irregularities. 

A sound example of this said sentence can be that when EPDM Liquid Rubber is applied over the poured concrete, pinholes will appear on the surface as the material slowly displaces the air in the pores. This surface wetting feature enables the product to be applied in a single coat over non porous surfaces and still result in complete film integrity.

Here are some technical properties of EPDM Liquid Rubber:

- 4-10 hours pot life but can depend on temperature

- On Firestone EPDM 4.85 pounds per linear inch when we talk about Peel Adhesion.

- 2000 hours Weatherometer

- 0.1 Permeability

- -62 degrees F Brittle Point

- 180-200% Elongation

- 680 psi Tensile

- 8 pounds Weight/ Gallon

- 1020 sq ft per gallon at 1 mil dry Theoretical Coverage

- 63.5% Volume Solid

The physical properties of EPDM Liquid Rubber are as following:

- Highly resistance when it comes to water penetration

- Ozone stable and ultraviolet

- Long term aging beneficial

- Broad temperature tolerance range

- Acid and alkali resistant

- Resistant to polar and alkali

- Polar solvents resistant

- Withstands ponding water even when not cured

- Weakness-oils, fats and waxes will swell the polymer.
