Are you satisfied with your cement roofing sheets? After how many years did they need to be repaired? What are the roof material alternatives for cement roofing sheets?
In this article we are going to talk about cement roof panels and compare it to UPVC roofing sheets and some other roof construction materials. The pros and cons of this type of roofing. Finally, you will have a clearer picture of your ideal roof and which one to buy.
What is Cement roof coating? Roofing cement contains asphalt, reinforcing fibers, and plasticizers. Roofing cement is also used to repair damaged areas in roofs and can save your both time and money.
Cement is a fine powdery substance with cohesive properties that adheres to walls and building materials such as bricks, tiles, sands to make infrastructure. But as much as it is useful, it can have some disadvantages, too.
Fire-resistant
To improve safety, we need to use fire-resistant building materials. Cement roofing can prevent damage to the building. So it is a good choice for buildings in high temperature places.
Cost effective
While concrete is more durable and stronger, but cement is considered a more cost effective building material. That is why builders choose cement to pay off for couple of years.
A good binding construction material
The reason many builders choose to use cement as a special construction is because of its binding properties. When water is added to cement in good proportion, a chemical reaction within the cement happens that adheres to its ingredients.
Cement is always available
Since its ingredients are found abundantly in nature, Cement can be found easily in local markets. Its raw materials are easily produced in form of cement.
What are the disadvantages of cement roof tiles? Here are some of the problem occurring in cement roof tiles?
Which cement is best for roofing? There are 2 types of cement material which are widely used in roofing.
When it comes to roofing, Ordinary Portland Cement (OPC) can be one of the best options. On the other hand, Portland Pozzolana Cement (PPC) has high compressive strength which makes it suitable for roofing sheets and building constructions. It also has a good water proofing properties.
Furthermore, Fibre cement sheets are becoming popular and are preferred for roofing systems and cladding.
Fibre cement is a composite building material and is made of cement, cellulose fibres and sand. It is strong and durable and can be used in building cladding, too.
Yes, cement roof tiles cost. Although Cement roofing tiles price are less than uPVC roof tiles. But uPVC price leads to longer life of the roof tiles and less roof repair cost. Hence uPVC roof sheet is a more cost effective roofing material.
The average lifespan of concrete cement roof tile is 50 years – if used correctly. While concrete roofing tiles are durable roofing materials; its underlayment will only last about 20 years.
Flat fibre cement sheets are mostly used for external applications and cladding. They are also used for internal use in roof ceilings and floors, etc.
Fibre-cement flat sheets consist of cement or calcium silicate binder, reinforced by mostly organic and synthetic fibers.
Asbestos roof tiles are water resistant and heat resistant. They last for many years but they also have some problems; which convinced many people to remove them and pay for removal cost.
Generally asbestos roof tiles are safe and durable, they provide protection for a building for many years.
But when they are moved or broken, then the microscopic asbestos fibres become airborne and enter human lungs or contact the skin and enter into the body. That’s where they can lead to illnesses and be fatal.
Cement and concrete are often used interchangeably, but cement is actually an ingredient of concrete. There is no concrete without cement. Cement is made of crushed stones, but concrete contains cement and water, larger rocks, and chemical additives.
Concrete is stronger and more durable than cement. Cement is a durable material, but cannot be compare to concrete. While concrete is used for large projects, cement is usually used for smaller, more decorative projects.
Which one is cheaper? Concrete or cement roofing sheets? Concrete roof covering materials are made of cement and other ingredients. So concrete is more expensive than cement.
Clay tiles are not immune to damage. When exposed to freezing or high temperatures, they may crack or shatter; while cement concrete is more durable and can handle extreme temperatures better.
UPVC or Unplasticized Polyvinyl Chloride, is a low-maintenance high quality construction and building material. UPVC is a cheaper option to expensive wood and aluminum. Due to its durability and cost-effective option, it became a popular material. It is also known as PVC and PVCU.
Here we are going to compare cement roofing sheets and uPVC roof tiles. At the end of comparison, you will know how much more affordable and durable UPVC roof tiles are – compared to cement, concrete and even clay roof tiles. For better decision, please read our previous article on glazed clay roof tiles.
One of benefits of concrete roof is its nonflammable property. Concrete is durable and strong, and fire-resistant. In case of a fire, fireproof roof tiles increase safety of your property and save your money.
Concrete roof tiles may crack. Why do they crack? Concrete roof tiles might crack when you walk on them. One reason might be your weight, which is more than the strength of the concrete tiles. Another reason can be the rubber ingredient in it; or can be simply due to falling objects that can impact the roof. Exposing to high heat and coldness is another reason why they may crack.
UPVC roofing sheets are lighter in weight. They are more durable and stronger than cement roofing sheets. UPVC roof tiles will not crack like cement tiles. UPVC roofing sheets are impact resistant. You can walk on them during installation and it won’t break or shatter. UPVC heat insulation and its overlapping tiles are very protective; hence its sealing is more effective than cement roofing sheets.
Class A is the Best fire resistant roofing material. Some of Class A roofing materials include uPVC roofing sheets, composition shingles, concrete and clay tiles.
Cement is an ingredient of concrete and concrete itself is not waterproof. It will leak if not waterproofed effectively. To waterproof a concrete or cement roof, a waterproofing membrane is considered to be the most important part of the roofing system. It helps to keep the water out of the building.
UPVC is a high quality roof sheet fire resistant material. It is made of polyvinyl and is a flame retardant building construction material. Fire resistant uPVC roofing sheets can withstand extreme heat, pressure and impacts.
One of the disadvantage of cement board is its weight which makes handling difficult. Cutting of cement board is hard and must be done with carbide-tipped tools and saw blades.
Sepid-Fam Varna is a professional manufacturing and Distribution Company: Producer of a new generation of uPVC sheets for roofing & cladding and sandwich panels – under the brand name “Polyroof Erica” – has started its activity since 2013. With cooperation of professional technicians and well-trained marketing experts in Iran, we ship our products to all over the world.
Some of our best products:
UPVC Eco-panel or sandwich panels for roofs and walls: It is an insulated roof panel consisting of 4 layers. The first layer is anti-UV polymer alloy. The second is UPVC. The third layer is elastomeric laminated aluminum foil.
These Eco-Roof Panels can have various applications based on insulation thickness. It is more economical compared with existing conventional roofing systems.
UPVC roof sheets can overlap each other and be welded together. Since they are waterproof, they do not leak and drip, so they are best anti-corrosion roofing sheets. But in cement roofing sheets and concrete roofs, due to their brittleness and cracking, they are more susceptible to leaking.
What we Offer at Sepid-Fam Varna
Our uPVC roofing sheets are widely used in various constructions such as: Canopies & Awnings, Industrial sheds, Villas, Houses, Livestock buildings, Warehouses, etc.
