5 Factors to Consider before Choosing a New Flat Roof

.


Flat roofing systems can be made using different materials and when it’s time to choose the ideal one, you need to take your time and make a good decision. Flat roofing materials that are easy to install, versatile, affordable, waterproof and durable should be your go-to options. Getting an expert to advise you on the types of flat roofing you should consider is paramount. While in the process of choosing a new roofing system for your flat roof, you need to consider some factors about your building, the current roofing as well as what you would like to achieve with the new roof. Going over these factors will help you make the right decision and invest wisely on the flat roof replacement project. We’ll go over 5 important factors that you should consider when deciding which flat roof is the best.

What are the drainage requirements?

One of the reasons why many property owners consider a roof replacement is because of drainage issues. If your current roof has a poor drainage system that you would like to enhance, you may need to perform repairs on the roof deck before installation to fix the drainage. The other option is to go for modern roofing systems with better drainage, so you don’t spend much on repairs.

What’s the slope of your roof?

The slope of your current roof will really determine which materials are best suited. Traditional materials such as shingles and concrete tiles are often not recommended on flat roofs with no sloping simply because they rely on water running quickly off the roof to remain effective. Single-ply roofing materials will also not work on roofing that is too steep. Therefore, you will need to settle on roofing options that work well for the slope of your current roof.

How much load do you expect on the roof?

If you often use the flat roof for storage, then the expected structural load will determine what kind of roofing system suits you best. Look for roofing materials that are robust if you expect heavy load on the roof occasionally. Avoid coatings and instead, go for spray foam which is designed for heavy loads.

R-value

Perhaps one of the things you want to achieve after replacing the roof is to save money on energy bills. Installing an energy efficient roofing system with a higher R-value is always a great idea. Think of materials that reflect the sun and compare them to those roofing solutions that help insulate as a way of lowering energy costs.

What’s the condition of your roof deck?

The state of your roof deck will also determine what kind of solution you can go for during flat roof replacement. If the roof deck is too weak, the surface may not be able to hold any equipment or additional weight during installation. You may need to choose a roofing solution that can be applied on top of the existing roof. Alternatively, you’ll need to have the roof deck repaired first before any new roofing is installed.
