What is roofing?
Roofing is a form of decking for your roof. It is to be applied over the initial layer of your roof and will determine the texture and outlook of your roof for years to come. Like other parts of the home, the roof is commonly overlooked, and yet it is one of the most important aspects of a house.
There are a couple of different types of roofs, each with their unique characteristics.
- Gable/pitched roofs. Usually shaped triangularly.
- Hip roofs. Similar to pitched roofs, but hip roofs consist of four sloped sides.
- Flat roofs. Flat roofs have the issue of not being able to drain water properly. Hence, it usually requires waterproof materials. Here is our curated list if you are looking for waterproofing companies.
- Mansard variants. A combination of hip and flat roof. Common for larger homes with a larger square feet area. This roof combination is meant to cure the water drainage issue of the former option.

What to know about Roofing in Singapore?
Some roofing projects might prove to be tougher to complete than others. Detrimental damages to your roof might cause you to dig deeper into your pockets or delay your project timeline further. Either way, you need to communicate effectively with your contractor to receive updates and understand the situation better.
There will also be plenty of excess material being demolished, removed, and reinstalled on your property. Responsible contractors should help homeowners out with the debris and cleaning stage. However, dust might also accumulate indoors during the project. Homeowners might need to make the necessary cleaning arrangements beforehand.
After the roof installation process, you should check your roof for any defects or potential mishaps for the upcoming weeks and months. Make sure that no tiles are sagging or loose. Roof maintenance should also be performed regularly, at a pace of once every quarter of the year. Cleaning the gutters and getting rid of leaves above your roof would help to declutter the roof surroundings and prevent pipe blockages and unsightly situations such as moss or fern growth. In Singapore, it is better to schedule your roof maintenance nearer to the end and start of the new year, as debris might accumulate after the rainy season nearing December.
Price of Roofing Materials
You can check out the prices of the roof in our article. The cost of PVC roofing is approximately $2-$3 per square foot, whereas polycarbonate roofing sheets can cost up to $4 per square foot on average.
Metal Roofing has a larger range for pricing per square foot, due to the many different materials. Steel and aluminium are cheaper options, sitting at $3-$5 per square foot. This is followed by copper and zinc options, which sit at the price point of $7-$9 per square foot. Lastly, tin exists as a premium option that can go as high as $10-$12 per square foot.
Square foot pricing for EPDM rubber roofing varies but expect to pay about $8000 to stall an EDPDM membrane on a typical roof in Singapore.
Different contractors may also charge different prices for materials. For roof contractors in Singapore, you might experience a steeper price tag due to the import of roofing materials from overseas, especially for niche materials such as Slate.
Layers of your Roof
- Decking. The flat surface of the roof. Similar to the roof’s basic flooring.
- Underlayment. The water-resistant barrier material installs directly above your roof deck.
- Roof Covering. The secondary layer is overlayed across the underlayment.
- Shingles. A strip of materials that go at the edge of the roof after the decking is installed. It prevents water from breaching the roof.
- Flashing. In some cases, there are also metal flashing installed around the edges, to direct water flow to the gutters.
- Gutters and pipes. Gutters and the pipelines function to redirect the flow of water traffic back to the ground.
How to perform Roof Repair in Singapore?
Clean gutters are extremely important for Singapore houses to avoid water damage. Clogged gutters would allow rainwater to splash over to the sides of the walls, damaging a home’s exterior wall tiles and foundation. This might result in discolouring of the outside concrete and painted brick walls, leaving unsightly streaks of discolouration along the house’s exterior.
It is also important to remove stagnant water from roofs to prevent the breeding of mosquitoes. Considering that roof stagnant water is one of the leading cost of mosquito breeding in Singapore, for health reasons alone, it is important to prevent a dengue cluster from forming near your home.
Benefits of Roof Replacement
A roof replacement might net you more benefits than you realise.
- Improved ventilation
- Wind protection
- Solar Reflection
- Better Security
- Improved Comfort
- Better Resale Value
A new roof might also raise the resale value of the house, as it attracts a potential buyer to see it as a new home due to the improvements made to it. This means that roofing can be seen as a wise investment choice or home staging option for homeowners looking to sell their home soon. If your roof is still in good condition, we recommend just engaging in roof cleaning services to save money.
Benefits of Regular Roof maintenance
- Improved roof integrity
- Cost savings on roof repair
- Removal of Health Hazards
- Extend the lifespan of your roof
- Aesthetic improvements to your home’s exterior
- Prevention of roof leakage

Advantages of Different Roof Types
- Asphalt Shingles are one of the most popular roofing materials due to their affordability and ease of installation. They are also known for their durability. Higher-quality shingles are even capable of withstanding up to 50 years. Asphalt shingles also have fire-resistant properties, although not as much as metal roofing provides.
- Wooden shingles, one of the oldest options in the market today, have been around for centuries. They are usually manufactured using hardwoods or composite wood materials such as plywood. In terms of durability, you can expect about 30 years of life from them. Wooden shingles are attractive options for homeowners looking to have a natural brown look to complement the surrounding greenery. It would also help if homeowners are looking to have artificial grass on the premises. Made from natural, biodegradable recycled materials, wooden shingles also get a plus point for being environmentally friendly options.
- Metal roofing materials also often come with an anti-rust metallic coating. The coating also has the aesthetic benefit of offering a wide variety of style and colour to complement the homeowners’ needs. Metal roofing is also fire resistant. This could lower your home insurance rates and improve the resale value of your home, as it brings an added layer of security to the home that home fences cannot offer.
- Concrete and slate roofing tiles are the most durable option, offering a century worth of protection to the building. However, a factor holding them back is its aesthetic outlook, which complements only a certain niche of home design and theme. Nevertheless, its structural capabilities are something worthy of praise.
Disadvantages of Different Roof Types
- Asphalt shingles, despite its capabilities, are more vulnerable to strong winds and heat as compared to the other roofing materials listed. For a warm and humid country like Singapore, it’s lifespan might be shortened to 20-30 years of life. They are also not considered to be environmentally friendly, as its production process contributes to greenhouse gas emissions. This factor might turn homeowners away from this option.
- Wooden roofs are known to be more expensive than other roofing options. It would also require additional and regular fire protection. Besides, maintenance on a timely basis is also important to prevent the roof from warping or cracking. Terminating infestation is also the worse of your nightmares.
- Metal roofing can also be costly. Not only do the per square foot cost need to be factored in, but the installation process may also require additional manpower and equipment, which contributes to the cost. This can range from $20,000 to $30,000.
- Concrete and Slate roofing tiles are extremely heavy. Such a heavy strain on the structure of a home would not be possible without prior evaluation and preventive measures. Hence, it would be important for you or your roofing contractor to consult a structural engineer.
Factors to consider for Roofing in Singapore
- Budget. It is important to consider your budget for your home during a roofing project. This will affect the choice of roofing material you go with and the scale and type of roofing project you are looking to embark upon. Some projects may carry a heavier price tag but can end up being more cost-effective. Hence, homeowners should think of the long-term cost-benefit analysis and not be too short-sighted to consider only the immediate benefits and problems.
- Roof Replacement vs Re-roofing. The former involves a complete replacement of your roof materials. There will not be a single tile or trace of your previous roof. The latter option, however, is similar to a refurbishment, where you overlay the old layer with a new one. The former involves a larger project, where the old roofing system would be completely dismantled and reinstalled. Hence, the budget for roof replacement would be higher. However, there are benefits attached to the price tag. Your roof would be more durable and have a better visual appeal. Homeowners should consider which option is more cost-effective for their situations.
- Accommodations. Depending on the range and scale of the project, roofing renovations might require homeowners to temporarily relocate elsewhere. Sometimes this involves moving out of the house temporarily. This would mean a change in lifestyle and surroundings. Either way, it would be good to discuss with your roofing contractor the timeline and impact of your roofing project.

What is Waterproofing?
Waterproofing is a niche in the construction and maintenance industry. It is a tall order, as there isn’t a one-size-fits-all solution for waterproofing. Different areas, due to the different materials and characteristics, require different solutions. The key is to identify the area to be waterproofed and use the most suitable method and product for it.
Structural buildings usually have waterproofing done during construction. Such is the case for HDB flats. There are many reasons you would want a piece of furniture or area to be waterproof.
Basements, deckings, toilets, or laundry rooms are common areas in the home for homeowners to opt for waterproofing services. Decks are probably a more challenging project, as they constantly move with changes in temperatures, putting stress on the waterproofing systems. Another specialized area of waterproofing is rooftop decks and balconies, in order to prevent water damage to the external structure of the house.
Types of Waterproofing projects
Some water leakage problems require extra manpower and equipment, making it difficult for a homeowner to perform it themselves. Some common such situations would include:
- High-Pressure Polyurethane Injection Grouting. The process to repair water seepage from concrete structures or walls.
- Epoxy Injection Grouting. To repair structural damage
- Torched-on Waterproofing Membrane. A common practice for roof waterproofing
- Fibreglass Waterproofing System. For roof or exposed surface waterproofing
- Low-Pressure Polyurethane Injection Grouting. To repair water seepage from electrical conduits or trunkings
