Any roofing loses its original appearance over time. In parallel with this, destructive processes are taking place that change the performance characteristics of roofing materials for the worse. Constant exposure to sunlight, snow and moisture, and temperature changes negatively impact the condition of the roof.
Repair work and errors in installation technologies, the use of low-quality materials are coming closer. Leaks cause the failure of the rafter system or deterioration of the performance of concrete floors. When choosing a material for roof repair, it is necessary to proceed from the features of the roof structure. Whether it is necessary to restore a metal or soft roof, mastics and sealants are used during the work.
When choosing a material for the roof, many stop at metal: galvanized iron, profiled sheet or metal tile. The service life of such a roof is at least 15 years, after which leaks may appear. You can eliminate them using patches from the same material from which the roof is created.
The places of their installation are preliminarily cleaned of rust and dirt. After that, pieces of metal are soldered, overlapping the damaged areas by 5 cm. Places of joints, abutments to walls and structures are repaired with sealants and bituminous mastics, using geotextiles for reinforcement. Seam roofs require a thorough inspection of all seams; they can be coated with a sealant before crimping.
On industrial buildings, roofs have a large area. Therefore, inexpensive roofing material or roofing felt is used as a material for the roof. Such roofs require regular inspection, during which swelling and damage are detected. The identified weak points must be promptly repaired. Otherwise, their area can quickly increase.
The material for repairing the roof will be the same roofing material or geotextile, which is coated with mastic. Such patches should be 10 cm larger than the size of the damaged area along the entire perimeter. For the soft roof not to cause problems, it is necessary to regularly process it with waterproofing mastic. Depending on its quality, it can form a protective layer that preserves the roof’s integrity for up to 10 years.
Roof repair must be entrusted to professionals; the cost of the service largely depends on the materials used. Experts will carry out a visit to the object, assess the amount of work and make an estimate. High-quality materials for roof repairs have a cost that is several tens of per cent higher than cheap materials, but they last several times longer.
There are many products on the market today designed to restore the waterproofing contractors NY of various roofing materials. Domestic roofing materials are trendy. Created using modern technologies, they meet all quality standards, environmental and fire safety, and affordable prices.
The roof structure is directly dependent on the climate in the region. If there is a lot of precipitation, then its slope is at least 45 °. For regions with strong winds, pitched options are rarely chosen.
For a roof that meets all the requirements of a challenging climate, you need to find a middle ground. It should be remembered that the stronger the slope, the more expensive it will cost since more materials will be needed.
The choice of the face material also depends on the slope. Roof tiles or slates are suitable for slopes with a slope greater than 20 °. If this requirement is not met, water will seep into the joints. Flat roofs are also covered with rolled bituminous materials. In any case, their slope should not exceed 30 ° since heating from steeper slopes can cause the material to slide. Polymer coatings are suitable for any construction. For metal tiles or steel sheets, the slope must be at least 10 °.
Slopes are available with and without a slope, and the first type of roofing device has several options:
Bituminous-polymer options are somewhat flexible coating. They have a disadvantage – they require a multi-layer roofing device and use during open fireworks. However, the roof is waterproof and durable.
Slate is a durable, solid and fire-resistant material. Today, options are available in different colours. Roofing felt (roofing felt) is performed on a cardboard base. It is often used for a vapour barrier. The main disadvantage of such a coating is a sensitive reaction to atmospheric phenomena and temperature changes.
Galvanized metal sheets are an environmentally friendly material that is resistant to corrosion. Serves up to 75 years. Shingles have several advantages. The traditional clay version has stood the test of time and is still in use today. The disadvantages include a lot of weight and difficulty in work. Cement-sand (Frankfurt) tiles are made from cement and sand. She is not afraid of fire, water, high temperatures.
Soft tiles are made of fibreglass impregnated with asphalt mass. From above, the tiles are covered with stone or mineral chips of various colours. It is several times lighter than clay and has a service life of 25 years.
Metal tiles – sheets with imitation of the pattern of the laid tiles. Due to this, the number of joints is reduced, resulting in labour costs during installation. The metal on it is covered with coloured plastic.
Any roofing device forces the floors to rest on a supporting structure consisting of lathing and rafter trusses. At the top, a rafter is laid for the device of the ridge. Today, ready-made truss structures are produced, sold disassembled.
The basis for a material called sigma roofing is fibreglass. It does not rot, which makes it different from the paper used to produce roofing material. The second component is high-quality bitumen, to which innovative polymers are added. This makes the coating durable.
A sigma roof, which varies greatly depending on the brand, has a top layer of stone granulate. It protects against external influences and provides a long service life of up to 50 years.
It is believed that only wealthy people can afford such a roof. Indeed, shingles are not cheap material. Although, Russian counterparts are now offered at a reasonably affordable price. It is more expensive than the usual roofing material and slate. However, the quality and durability of the result more than cover this fact. It is impossible to save on roofing, as well as on the foundation. The service life of the entire building will depend on its quality.
It is believed that a sigma roof breaks and cracks in the cold. Sometimes this happens if the manufacturer uses oxidized bitumen, which does not allow the material to become resistant to mechanical stress and low temperatures. But the use of SBS modifiers makes it more plastic. Improves performance and memorable HDPE films made on the back surface of the shingles.
Another myth is that the material deforms in the sun, and the boards become visible. This is not true if you follow the installation technology and do not use raw wood or low-quality plywood. Experts advise choosing OSB boards, naturally dried edged boards or moisture-resistant plywood.
Some believe that sigma roofs lose colour during operation. This is not true because the stone dressing is coloured by a thermochemical method, due to which the granules do not fade. It is widely believed that installation is complicated at low temperatures. It is easier to do the work in the summer. But in winter, installation is possible subject to simple conditions:
The price of a roofing contractors NYC varies depending on several factors. In the first place is the brand of the material. A large selection of manufacturers allows you to choose an affordable option. The design features of the tiles are the second component. It can be of various shapes, colours or types. There are metal-coated proposals with a bottom glue strip, etc. To determine the most suitable option, it is better to contact the managers of hardware stores for advice.
Buy roofing materials from trusted suppliers! Make your home cosy, comfortable and dignified! After all, home is the prominent place for every person.
Roof repair begins with its inspection. The coating diagnostics aims to determine the amount of damage and the financial costs for their elimination. However, repairs should not be postponed – it is much more profitable to eliminate minor defects. In the process, the places where water penetrates inside are found out, and the condition of the entire “roofing pie” is assessed.
No matter how well the material was selected and the work on the roof was carried out, at some point, it begins to need repair. There are several types of reconstruction:
The first step is to get rid of the worn-out part of the coating. Then, work takes place on the restoration of wooden or metal supporting structures. Further, they are treated with antiseptic and fire-retardant substances. If damage is found to the vapour barrier, it is restored. Then the roofing is arranged, work is carried out to replace the gutters.
The soft roof is a general name for many building materials based on oxidized bitumen and fibreglass. Technology makes them durable and beautiful.
However, even with proper operation, they may need to be repaired since they are affected by many damaging factors (solar radiation, aggressive atmospheric precipitation, hurricane wind, significant fluctuations in daily temperatures). Impacts, pressure and chipping also do not extend the life of the material. The roof begins to need repair, as deformations, cracking appear, fungus grows, the protective layer wears out.
Significant works involve a complete change of coverage. During current repairs, a partial replacement of elements is made. The most progressive method today is the “sintering” method. The old technology repair process had the problem of disposing of the removed coating. In addition, moisture got into the holes formed. In the process of dismantling, the screed was damaged, which made the cost of the work more expensive.
All troubles are avoided by the “sintering” method. The old coating heats up and turns into a monolith with a new one. The moisture between the layers evaporates. For this purpose, special equipment based on an infrared emitter is used. 7-8 layers of the old roof can be used.
Whatever the complex problem with the coating on the roof of the building, experienced specialists will always find a profitable solution. Repairs carried out on time will not allow walls and foundations to collapse and save you from unnecessary expenses.
