Roof repairing Problems with Solutions

Roof is the greatest source of protection from any type of whether condition for the world. But they have to spend more for its repairing and remodeling almost every year especially after rainy and summer season. Roof Leaks are mainly the cause of improper installation and ineffective flashing of roofs at the time of its construction. Roof Leak may occur about any place of the roof buy they found more near the chimney, step, apron, pipes, and points at which two roofs meets. Roof leaks may also occur when your roof shingles installed improperly. If you ignore it for a long time, then they may become a cause of major damage for of the roof.

The next Cause of roof leaks is the weather condition also, some time summer sun become a cause of generating this problem with roofs and some times summer season result for this problem. In USA, thousand of people have to spend at least $12 billion every year only for repairing their roofs. For this purpose they have to contact with roof repairing and constructing experts who can fix all these type of problems of their roof. The season exposures can play a huge harmful role on the health of this part of home. Many natural elements like wind, circles, rain, snow and more lead to damaging effect on the roofs of homes.

It is important to ensure that your roof is equipped with building materials that are appropriate to the weather conditions of the area that you live in. Choosing cheap, low-quality materials that do not handle well in certain weather conditions can prove to be a very expensive mistake. This type of mistake especially at the time of construction leads to bear heavy cost of repairing near about each year or in every season. You can minimize the problem by selecting the material that is more suitable and having great resistance for all type of weather condition like EPDM and liquid rubber designed specially for it. Elastomeric roof coatings and liquid rubber are also designed for roof leaks due to draining water in rain; provide great resistance for water in rainy season. Similarly epdm is the best product for summer sun that can easily control the temperature by providing complete protection to the roof from sunlight.

For the durability of a roof, at the time repairing is very important, because roof leaks convert into the major roof damaging problem those have no solution instead of reinstallation of the roof.  Many homeowners do not realize it until it is too late, but there are many situations in which roof repairs must be done because the roof was improperly constructed and designed. These complications may include weak structures that buckle easily under pressure, a slope that is considered to be inadequate, selecting materials that are not durable enough to withstand the overall shape and design of the home, and even selecting materials that are not considered to be quality enhanced and hold up to certain weather conditions.

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 your self. 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.

Roof Repairing Guide

There are all kinds of roofs. If your own happens to be quite flat, and your house is a one-story building, so that you can reach the roof by using an ordinary ladder, there is little danger in venturing out on it, but if you have to crawl through a window and claw your way around on a steep roof, you will do much better to stay away from it. However, there are a few basic rules for safe roof work which every homeowner should be familiar with.

roof repair

Many people do not realize they have a problem with their roof until the inevitable happens…..roof leaks. More often than not, that is when a roofer receives a call to perform a roof repair – only to find that the whole roof needs replaced. Some are frustrated when they are being apprised of this situation and believe the roofer may be trying to “sell” them something they may not need. Be aware that roof repairs cost more on a hourly basis then replacing a roof. It would take “only” approximately two days of doing roofing repairs to equal the same amount paid in labor for an entire week when replacing your roof.

If a leak is recognized, clear the area of any home belongings, for instance electronic equipment furniture, etc. Place a bucket to collect the water for the time being. Once you can clearly see where the water is dripping from the ceiling, take a ladder and look at the roof in that area. You might easily see a part of the roof that has a broken shingle; you might also see debris, loose flashings, etc.

The Roofing Process

A moderately sized roofing job might take only 3 or 4 days.

  • Remove all existing shingles, deposit them in a roll-off, and remove.
  • Begin to make minor repairs on roof if in good condition. If not, replace bad wood with plywood or 1″x6″ boards, whichever is applicable to your roof.
  • Install the “ice dam,” which is an ice and water barrier made of plastic to prevent backed up ice in the gutters from working itself under the shingles.
  • Lay down asphalt paper.
  • Apply the shingles – starting at the eaves and working upward.
  • Apply flashing around all areas where leaks might come into the house – against the chimney, stack vents, etc.
  • Install the ridge vent.

We need to cover a few things before starting any roofing project. These include:

  • Get Proper Information: Be aware this is a construction project and there will be noise and debris. Children love to watch what’s going on with their house but they must be kept away from the perimeter of the worksite, ladders and equipment.
  • Share Properly Your roofing Condition with Roofers: Roofers generally do their best not to drop debris into shrubbery or flower beds but it is sometimes unavoidable. Inform roofing company if you have delicate flower beds or shrubbery that needs special protection.
  • Point out sprinklers: that heads along driveways and sidewalks to help us prevent damaging them.
  • Roofing is a noisy job, including hammering and power equipment. In most instances we will finish the job, including a thorough cleanup, in less than two days.
  • Hanging Items on walls should be removed: Loosely hung items on walls should be removed. Also, bring in flower pots or other yard objects close to the perimeter of the roof.
  • Inspect your building condition completely: If you have wood shingles, be aware that dust and debris particles will fall into the attic during the tear off process. You may want to cover some items in your attic with protective cloth or plastic.

Many roofing problems, including shorter than expected life spans, are the result of improper material selection in the first place most roofing decisions are made on the basis of first cost or appearance and local climatic conditions are often given too little consideration. Hail, wind and freeze/thaw cycling are particularly hard on most roofing materials. Start by understanding the local climate your roof must deal with.

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.

Roofing Industry Market Review

Residential roofing demand is primarily driven by replacement market which has covered a large part of the market whereas new construction drives the market to a lesser extent. Within the replacement demand, approximately more than three-fourths is non-discretionary replacements due to deterioration with age or weather damage.

As a repairing of Roof leaks Liquid Roof is used for RV Roof Repair. For this purpose, there are many products like liquid rubber and roof leaks repair, very frequently used by the builders for construction. But it increases the expenditures and applying cost for building or repairing a house. Every fiscal year marks inflation and the prices of having long term usage products changed in up direction. That’s why the prices of roofing material gradually increased with the passage of time. During 1997 the review of construction shows that near about $40 million spent for roof repair but cost included extensive amount of work and in 2002 great increments in prices is recorded. With proper maintenance and coating, a low slope roof can last significantly longer than its expected or predicted life.

Liquid Roof Application

Liquid Roof Application is best with a squeegee and a fine nap roller. Before applying, mix the pre-measured catalyst by following label directions. A single application is preferable to multiple coats. Touchups may be applied as desired after initial film has cured and surface is first wiped with solvent. To insure its effectiveness it must be applied at a 20 mil layer . Apply with brush around flashings and edges using long, slow strokes. On flat surfaces, material can be poured, spread with a squeegee and then evened out with a short nap roller. The Product will level itself when sufficient material has been applied. Liquid EPDM Rubber Roof should not be applied on cream color ALPHA rubber.

Adhesion

Adhesion will increase over time. Polar surfaces such as metal, concrete and wood result in stronger adhesion than non-polar surfaces such as asphalt and single ply EPDM sheet. Most weathered surfaces including single ply and thermoplastic membranes will have enough of a surface profile to anchor the Liquid EPDM Rubber. Liquid EPDM Rubber Roof has proven itself superior to acrylics, urethanes, and other elastomers as a moisture barrier. Due to ultraviolet rays and weather conditions, sealants become brittle and lose adhesion, resulting in leaks. One application of Liquid EPDM Rubber Roof will provide an air and watertight seal that will outlast the original sealant.

Durability:

By itself, the Liquid EPDM Rubber Roof membrane will exhibit the characteristics of its EPDM chemistry, i.e. U.V. and ozone stability, excellent pounding water resistance and long-term retention of flexibility. However, since it is always applied to an existing surface, the condition of that surface will determine overall life expectancy.
Liquid EPDM Rubber applied over generally sound single ply EPDM can extend its life another 20 years, The useful life of metal roofs also benefit greatly when Liquid EPDM Rubber Roof is applied. BUR systems often have existing problems such as delaminating between layers, buckling and stress cracking. These are further aggravated by wet insulation which often results in severe corrosion and weakening of the metal supporting deck. Projecting a life expectancy for the EPDM Liquid Rubber membrane ultimately comes down to a case by case determination. When the EPDM Rubber membrane is compared to urethanes, acrylics and other elastomers in accelerated weathering and heat aging tests, the EPDM Rubber shows itself to be superior.

Liquid EPDM Roof Coatings are aftermarket products designed to extend life, seal leaks, provide a heat reflective or aesthetic function over existing roof surfaces. Now you too can enjoy the many benefits of a weather-tight EPDM Rubber Roof. Liquid EPDM Roof is a unique form of EPDM rubber. As a liquid, it can conform to any shape of roof, flashing, or protrusion, vertical or horizontal, and can be applied easily with a paintbrush or roller on your roof. Roof repair with Liquid EPDM Roof is now very easy.

Surface Preparation:

Liquid EPDM Roof/Liquid Rubber/Liquid Rubber may be applied on roof decks, gutters, structural steel, air conditioner enclosures, cooling towers, galvanized steel, unit heater flues, smoke stacks and chimneys, fiberglass and non porous masonry surfaces. Surface to be coated should be clean, dry and structurally sound. Fasten loose areas with adhesive (contact cement) or pop rivets. Oil or wax must be completely removed.

All surfaces to be coated should be clean and dry. Remove peeling paint and brittle caulking. Heavy build ups of asphalt roof cement should also be removed. Tighten any loose fasteners and replace those which are severely corroded. Repair or replace roof panels damaged by storms. Remove heavy rust with abrasive discs or wire brushes. Power washes all surfaces to be coated and allow drying thoroughly. Caulk all gaps wider than 1/16 inch which are not expansion and contraction slip surfaces.

Remove loose portions of existing coatings and brittle caulk with scraper and wire brush before using Liquid EPDM. Whatever still has good adhesion may remain to be re-coated.

Rusty or pitted metal should be wire brushed to remove loose oxide. Tightly adhering corrosion may be re coated. Asphalt based aluminum coatings should be removed as much as possible by wire brush or abrasive disc. Roof cement should be removed and replaced with butyl caulk where necessary.

Repair torn rubber by re-gluing loose areas with contact cement. Coat exposed edges with contact cement to prevent solvent absorption from Liquid EPDM Roof/Liquid EPDM Rubber. A rubber patch may be applied over torn area if desired. Remove chalk from white rubber membrane by brushing with a detergent solution followed by a water rinse or working surface with a stiff brush. Smooth metal or plastic surfaces should be roughed up to improve adhesion of Liquid Roof/Liquid Rubber A DE-glossing solvent may work on some plastics.

For Large Commercial Projects: Airless or Air Atomized spraying, Airless equipment needs only one hose from pump to gun but must generate 3500-4000 psi pressure and is limited in the length of hose which can be used because of high pressure drops. Air atomized equipment requires two hoses to the gun making it more cumbersome to maneuver plus the addition of a compressor.

Liquid Roof is the only liquid EPDM Rubber product currently on the market.
