Why Choose Us as Your Preferred Roofing Contractor

While our services and track record speak for themselves and the company, it’s the intangibles that set Alpha Builders apart from the competition. Here are the reasons why you should choose us as your number one roofing contractor in Singapore:  

Qualified Expert

Our roof builders have undergone extensive training in dealing with a wide variety of roof types, and they are prepared to give you high-quality service. We also understand the role roofs play in your daily lives; that’s why we don’t just treat our services like a job; we make it a point to tailor fit everything to your needs.

Flexible Schedule

We at Alpha Builders understand the importance of time, and since roof building or waterproofing can be time-consuming, we can devise a schedule that will be convenient for our customers. Perhaps you are at work 5 days a week and have only days off on weekends; we can adjust our schedule to fit with yours.

Workmanship Quality

Our years of experience in dealing with roofing and waterproofing made us who we are today. We at Alpha Builders pride ourselves on constantly learning and changing with the times, and it shows in the quality of our work. Our pre-existing knowledge about the services we offer is continually being bolstered with each job we take, which ranks our roofing and waterproofing contractors among the best.

Attention to Detail

Alpha Builders makes it a point to leave no stones unturned–literally and figuratively; that’s why we make sure to pay attention to the details. We understand that cracks can form in inconspicuous areas of your home, and we make sure to pay special attention to these areas so damage to these areas won’t catch you by surprise down the line.

Quality Professionals

Alpha Builders believes that work extends far beyond roofing, and we exhibit this understanding by providing you with quality customer service. From when you pick up the phone to contact us to when your installation finishes, top-notch customer service is guaranteed.

Dedication to the Craft

We do not just treat our projects as jobs; we put our hearts and souls into them, which shows in our work. When you choose Alpha Builders, you’re not just getting high-quality service; you’re also getting people who genuinely love what they do.

what we do


New Construction

Working together with house owners, architects, main contractors and managing agents, Alpha Builders selects and implements the best roofing solutions for any new construction project.


Roof Maintenance

We understand that proper maintenance is required to prolong the use of anything you have. With this knowledge, we make sure that roof maintenance is one of the areas we should focus on. Roof maintenance doesn’t just involve cleaning various dirt and debris off your roof; it also involves stringent inspection for damages that might cause more significant concerns down the line. You can trust that Alpha Builders have covered everything from cleaning to damage inspection. 



When the damages sustained by your roofs are too much, you have the option to re-roof. Re-roofing doesn’t just ensure that you will have a fresh look for your roof; it also offers additional protection and waterproofing for your homes. With constant development in the materials used for roofs, re-roofing also ensures that your roofs are up-to-date regarding the protection provided by these new materials. 


Metal roofing

Metal roofing is an excellent option for those who have longevity in mind. With the ability to reach up to 40-70 years, this roof type takes the pressure of worrying about re-roofing every 12-20 years. We at Alpha Builders are well-equipped and knowledgeable about metal roofing. Since metal roofs are low-maintenance, all you have to do is sit back, relax, wait for the installation to finish, and enjoy your new, durable, low-maintenance roof! 



The primary purpose of roofs is to protect our homes from the elements; one of the elements our houses need protection from is water. It can be pretty disheartening to see all of your life’s work within your home be damaged by water from the rain; that’s why proper waterproofing is needed. We at Alpha Builders pride ourselves on being excellent waterproofing contractors, and we provide protection for your roofs by combining our experience and the high-quality tools at our disposal. 


Leak Detection Survey

Over time, and through changing weather, cracks may form on your roofs, and leaks usually follow suit. The thing with leaks is that it can usually be pretty hard to detect where they’re coming from, but that’s where Alpha Builders come in. With our expertise in structural engineering, we can quickly identify damages to your roof, no matter how small they might be.

The best way to gauge whether you might need re-roofing is to note how long your roof has already been installed. Certain roof types have shelf lives, and problems might start to show once they reach the maximum number of years. Alpha Builders is the best Singapore roofing contractor to help you with your re-roofing needs. 

Factors like the shape of your roof, the weather, and your budget come into play when deciding which roofing material you should use. Right now, the commonly used roofing materials are asphalt shingles, tile shingles, slate shingles, wood roofing, and metal roofing. 

While there’s no one stopping you from doing the roofing yourselves, most DIY roofing projects don’t turn out well. Roofing contractors in Singapore have a job for a reason: to provide you with flawless and leak-free roofs.
