Roofs Types, its repairs and coating materials

When we get tired of the whole day’s activities our most imperative want becomes to go home and get relax. As the thought of going home comes to our mind a smile comes to our faces unconsciously because of a peaceful place for tranquil. Home is the place which gives soothing and comfortable thought to everyone. It serves as a shelter from all the outside and environmental harms. Roof is the most important element of the home construction and its most intricate thing to repair and re-roof. Before deciding on roof repair or repair decision, all of us must be aware of the expected roof lives.

All roofs are made from different materials and each type of roof has a different lifespan. The best way to determine how long you can expect your roof to last is to check with the manufacturer’s warranty. However, you should also realize that with a preventive roof maintenance plan that utilizes seasonal inspections, you could greatly enhance the lifespan of your roof. When considering roofing materials, always talk with your roofer about the steps that you should take to maintain its condition as well as anything that you should do to ensure that you don’t void the warranty. By taking the time to choose the best roofing materials for your house’s design, structure and geographical location, you will have a better chance of enjoying new roof for many years.

Most commonly, roofs fail because some aspect of the installation was done poorly. Many roofers don’t pay much attention to the details. Problems caused by poor installation often don’t show up for five or ten years. By the time there’s a leak, the home has changed hands or the homeowner has no recollection of who did the roof — let alone any idea where to find them. There are plenty of sloppy roofers out there that never even know about the problems their poor workmanship causes.

Then there are the lucky few homeowners whose roofs fail simply because the materials have surpassed their useful life. Typically these roofs go 20 years or more without a leak and replacement becomes obvious because many of the shingles are starting to curl or tear. Many roofs are covered with asphalt shingles. These shingles should last 20 years or more but often fail after about 15. If your roof is starting to leak and is 15 years old or older, there is a good chance that you’ll need a new roof soon.

All conventional flat roofs are exposed to surface deterioration under the action of sun, wind, driving rain, hail, ice and snow, traffic, building movement, temperature cycling and water ponding. It is because of this process of degradation that a roof must be inspected yearly. When a leak occurs in a flat roof, a more serious type of deterioration occurs. Even if water does not enter the building, it attacks the insulation. Destruction of the roof system can progress rapidly and cause damage for which repair is costly or impossible. This phase of deterioration is neither inevitable nor normal for a properly designed and constructed roof, and usually is merely the result of neglect and lack of maintenance.

It is difficult to comprehend how a roof, which is an expensive element of the building, can in many cases go on unattended for years. It is similar to buying an expensive car and being content to only add gas when necessary. Both car and roof will fare miserably before they reach half of their designed life.


Another aspect of roofing to consider is the material that is used for the underlayment, sheathing and trusses. If you are building a new roof, you should realize that all of these parts to your roof system would come with warranties as well as methods of maintenance and care. You should also have plenty of adequate ventilation included in your roof system to help preserve the life of your roof. Taking the time to discuss all of the options available with your roofer will help you to maximize the most from your roof.



The primary advantages of liquid roof coatings are their economical, proven performance life, and ease of use. Roof coatings are generally very good weather and water sealant. Today’s liquid roof coatings are versatile and applicator friendly. Non-flammable products are also available.


It’s important for you find a good coating for your roof: you want a coating that will protect your roof from the elements and make it last even longer than it traditionally would. You have several main choices for roof coatings. There are pros and cons to each. Roof coatings can be put on your roof at any time during the life of your roof. However, it’s usually best to put the coating on the roof when your roof is replaced or if your notice any leaks in your roof.


The most widely-used roof coatings product is the acrylic elastomeric coatings. This type of elastomeric coatings can extend the lifespan of the roofing system through a dependable protective finish. Elastomeric coatings are also preferred by green building enthusiasts because of its environment-friendly coating formulation.

Roofing Types & Problems

When we start talking about roofing problems, the first thing we need to know about is types of roofs prevailing in the market and the pros and cons of each roof type. Whilst Roofing is constantly exposed to the elements, structural shifting, and stresses as well as chemicals in the atmosphere all take their toll on your roof. Aging occur on all roofs, wear and tear stemming from neglect, abuse, contamination, and accident can result in expensive repairs or premature failure of the roofing system, if not detected. A Regular inspection program will help detect minor problems before they become big ones, avoiding interruptions of work going on inside the building, and most importantly, protecting the owner’s investment and adding many years to the life of a roof.

Roof Types:

Wood: There are two types. Shingles are cut to a specific size and smooth finished. Shakes are irregular and rough-textured. Wood gives a natural look to a home. It also requires more maintenance to protect it from the elements.

Metal: Metal roofs have returned from the olden days to become a popular roofing option. Once limited to low-slope structures, standing seam steel roofs can now be used on steeper roofs as well. Metal is durable, practically maintenance-free, heat reflective and non-flammable. Installed in sheets, a metal roof will actually dissipate a lightning strike rather than conduct it.

Built-up Roofing: Built-up roofs are installed on flat or very low-sloping structures. They consist of alternating layers of felt or fiberglass treated with asphalt. These layers are topped with asphalt (tar) or aggregate. Built-up roofs are more common in commercial buildings.

Tile and Slate: These are two of the oldest roofing materials around. They are long-lasting and durable. Their weight requires a reinforced roof structure that can support them. Both can be quite expensive and neither is easy to install.

Slate Roofing: is a very expensive choice, but it’s very beautiful and distinct.  Many Colonial and French homes look very appealing with this style of roof materials.  Slate roof materials are heavy, as you can imagine, and will need additional structural support.

Factors that affect roofs

  • Sun delivers a combination of ultraviolet rays and heat can prematurely age a roof.
  • Snow or ice that melts and refreezes (called ice damming) pushes up the roofing material and causes leaks. Ice damming can be a temporary problem that ends when the thaw is complete. Excessive amounts can damage the roof and roof structure.
  • Rain is normally kept at bay by a roof. But when rain or moisture gets underneath roofing, damage can occur.
  • Wind can remove any roof in the most extreme occurrence. However even minimal amounts can weaken a poorly installed roof by letting dirt and moisture get underneath.
  • Moisture from condensation underneath a roof not only harms the roof and sheathing, but also can cause problems inside of the house.
  • Trees provide shade to help cool a house. They also provide leaves and limbs that can fall or scrub against the roof.
  • Algae and moss get a foothold on moist surfaces. Excessive growth can retain moisture and cause eventual weakening of the roofing material.

Other Causes of Roof Problems:

  • Improper Installation
  • Improper Design
  • Lack of Maintenance
  • Flashing Failures

Each of these major causes of roof damage can be minimized by regular and careful inspection for early and minor problems. Immediate attention to any flaws or damages with competent repairs can help you avoid major damage to your roof and prevent the need for early and costly roof replacement.

Having a roof that leaks is a very common problem of many homeowners, especially if you live in an area that sees a lot of rain. When your roof leaks there are a lot of problems that can happen such as mold and mildew stains, damaged foundations, and water stains on the ceiling, just to name a few. Because of this it is important for you to have the knowledge of how to find the leaks in your roof.

When you do discover a leak in the roof you should not panic but simply know that it is time to fix the leaky roof. A leak can actually be a good sign as it will force you to check the leak and it is a good idea at this time to look over the entire roof to see if there are any other leaks or problems. Fixing a leak in your roof is not very expensive and it does not take a lot of time.

The Common Roof leaks problem can best be solved by using EPDM. It is compatible with all types of roof problems caused by sunlight, snow, moisture, rain wind and other causes etc. EPDM is the broader term among roofing material used for repairing, it includes liquid rubber. EPDM is compatible with almost all types of roof including flat roof, sloped roofs and other times of roofs mentioned in this article.

Roof Failures

The life of any roofing system is finite. Most low-slope roofing materials begin to exhibit water infiltration within 20 years after installation. Distress conditions and leaks on low-slope roofs are more likely to emerge at certain predictable areas, such as at punctures or seams in single-ply membranes. Roofing materials are subject to damage from strong winds and flying debris. Generally, roofs are not designed to withstand winds of hurricane and tornado intensity.

Leaks also often occur where pipes or vents penetrate the roof membrane, as well as at roof perimeters where roofing systems transition to other materials. By identifying areas that are prone to developing problems, maintenance and engineering managers can take steps that will prevent roof problems cost effectively. Less preventable source of roof leaks is roofing failure—that is, the structural failure of roofing materials. To make repairs in the most common roofing material—asphalt shingles—use the following approach:

  1. Go into the attic space during a rainstorm and inspect all the rafters or trusses with a flashlight. Look for damp or wet areas and mark them with a black felt marker.
  2. When the rain stops, look for any holes in the roof next to the leaking areas you marked. If you see sunlight coming through, you’ve found a hole. Push a small nail through each hole to mark these spots.
  3. Go onto the top of the roof and find your projecting nails. Push the nails back through the sheathing and fill the holes with plastic roof cement. Use cement that’s packaged in a caulk tube for easy application.
  4. If you see leaks around flashing for chimneys, plumbing pipes, or roof vents, fill these holes with plastic roof cement. Chip out the old sealant first with a hammer and cold chisel, and brush away any dust.

Every roof system can tolerate an optimum level of ponding water, after that it causes cracks on the roof surface. All roofs face any of the two conditions;

1. Every additional quantity of rainwater will cause a deflection that is bigger than the thickness of the rainwater layer causing this deflection. This means that the rainwater falling on the roof will flow towards the deflection, the additional weight of the water increasing the deflection further and so on and so on. Rainwater flowing over the edges of the roof will not take place. This will continue until either the rain stops, or the ultimate bearing capacity of the roof will be reached and the roof will collapse.

2. Every additional quantity of rainwater will cause a deflection that is smaller than the thickness of the rainwater layer causing this deflection. This means, that at a certain moment, provided that the ultimate load bearing capacity of the roof is not reached, equilibrium takes place, the deflection does not increase anymore and the additional rainwater falling on the roof flows over the roof edges.

Generally speaking, roof failures have common causes for all roofing systems.

  • Open laps: in the field membrane, but especially in the flashings, is another problem. Open laps are just carelessness on the part of the installer. Usually it means that the installer has failed to apply adhesive to the entire lap. Sometimes it is caused in built-up and modified bitumen systems when the bitumen is applied too cold. The laps appear to be closed, but open up as the roof ages.
  • Splitting: Splits occur frequently in expansion joints. The most common splits occur when a metal accessory is flashed with a membrane material. As the temperature changes, metals and membranes expand and contract at very different rates. Because the membrane generally cannot move as much as the metal, it will eventually fatigue and crack when it is adhered to metal. This problem is not as common with single-ply membranes with better expansion and contraction capabilities, but it is common in asphalt and coal tar systems.

Penetrations: Another common failure location is penetrations. Of particular concern are pitch pans. There are three failures common to pitch pans: the sealer itself, the container in which it sits and the penetration to which the sealant is supposed to adhere. Almost all sealers used in pitch pans will crack eventually due to loss of plasticizer or aging. If the penetration is not stabilized, vibration or movement of the penetration can cause the sealant to crack around the penetration. If a penetration is not thoroughly cleaned of asphalt before installing pourable sealers, the sealer will not adhere to the penetration.

Liquid Rubber Roof Repair

Liquid Applied Roofing Systems

Liquid Roof has had a long history of superior performance in hoses, molded products, tires and roofing membranes. For example, the radiator hoses in our cars and the gaskets on our freezer doors are made of liquid EPDM rubber and show the broad temperature range the product can handle. EPDM Roofing Membranes also have more than 30 years of successful history. EPDM is relatively inexpensive, simple to install, and fairly clean to work with when compared to conventional materials. There are not the strong odors and fumes either. The product is very stable and the resulting characteristics of Liquid EPDM Roof such as flexibility, weather ability and chemical resistance are determined by it. Liquid Roof therefore, can be described as a new form of an old and well-established rubber polymer. Now you can take advantage of the same benefits to weather-tight your leaks. Liquid Roof forms a 100% seamless layer.

Being liquid roof applied, these coatings are highly versatile. With traditional resurfacing materials such as felt, it can be difficult to achieve a 100% waterproof surface especially in areas where detailing is difficult. Protrusions such as pipes and surface-mounted roof lights cannot be easily detailed by these materials alone. By contrast, liquid waterproofing can be applied anywhere where one can reach – providing total, fully adhered and seamless protection.  A long-term solution to the problem of water ingress, liquid roof coatings are highly durable and long lasting, offering up to 25 years’ protection. The systems avoid the use of heat or flames and use specialist cold applied liquid resins of various types.

This is the common problem and faced by every house hold. EPDM Coatings Liquid Roof Coatings satisfactorily solve this problem. It is gives best results on RV Roof Repair as well.

Roofing Materials

When any one chooses roofing materials life of the material, cost, installation and its appearance are all the factors that he should tae care. Most of these considerations depend on the owner’s aesthetics or the specific type and location of the house. But installation cost and expected lifetime of the roofing are the most important factors.

Asphalt shingles are used in more then 90% home residential roof installations. People only go for Asphalt Shingles as its not the end of the story when we talk about roofing. Sheet metal, cement tiles, wood shakes or shingles, traditional slate or ceramic tile are all readily available. Biomass roofing is the use of plant materials to build roofs. People from around the world have always used whatever vegetation was locally available and abundant to build their roofs.

Below is the list of expected lifetimes of the most popular roofing types.


  • Asphalt shingles last about 20 years
  • Architectural shingles last about 30 years
  • Wide span metal roofing lasts 25+ years
  • Wood shingles last about 20 years
  • Concrete tiles last about 25 years
  • Clay tiles last about 45 years
  • Slate last 50+ years



Initial cost is just one consideration but life time of roof is the most important factor. Most popular Asphalt Roofing is last not more then 20 years but a good slate roof could last more then 50 year. For commercial projects, architects sometimes use a “life-cycle cost” comparison that factors in maintenance and replacement costs to justify spending today’s dollars on a material with lasting value. By that calculation, cement tile or even slate could be a good buy in the long run.


Once you’ve selected a roofing material, Pick a roofer with roots in the community, who backs up his work and will do a careful, thorough job on the details that count, like flashing, fastening, and sealing.


Now lets discuss some thing about the roofing materials type. Wood Shake roofing, its true that it’s the dream of many home owners because its always pleasing to eye. Wood shake is mainly cut from cedar, though you can also find pine wood shake. Metal roofing is one of the old type of roofing and now its rarely used in modern countries. Home owner do not want to use Metal roofing material as its life time is not that long and its not supportive to heat and cold. True slate roofing is nearly impossible for the do-it-yourselfer to install. Most homeowners who want the “slate look” bypass real slate and go for the “rubber slate” or “composition slate” roofing material. With composition slate, you can make your house look beautiful and feel good about it.


If you want to replace a roof don’t take it as an easy job. The cost to replace a roof, as you might imagine, varies. It varies according to your roofing materials (all the way from cheap 3-tab asphalt shingles up to architectural shingles or even slate), the roofing contractor, the pitch (or steepness) of your roof, the area to be covered, and a host of other factors.
