Pitch: The roof pitch is essentially how much a roof slopes. Even so-called flat roofs have a slight pitch for rainwater run-off, however some types of commercial roofing are legitimately flat. These roofs require expert rainwater management solutions.
Penetrations: Penetrations refer to anything that’s making a hole in your roof. This includes things like roof ventilation and chimneys.
Brand: You may have specific brands you like the reputation of. It’s definitely worth researching roofing brands or asking your contractor for advice.
Climate: The climate you’re building in plays a part in selecting your roofing materials, because you always want something tough and durable in difficult climates.
Intended length of ownership: While nobody sets out to build a bad roof, your investment may vary if you’re intending to sell the property quickly.
Foot traffic: Built-up roofs on commercial buildings often have people walking on them, whether for maintenance or other reasons. Obviously, the more foot traffic you expect, the stronger your roof will need to be.
Drainage: Drainage and rainwater management is always crucial. As we mentioned, built-up roofs are completely flat, so drainage becomes more complex than using standard gutters and downpipes.
Upkeep and maintenance: How much do you want to spend maintaining your roof? Certain types of roofing require more upkeep, so keep this in mind when building.
Aesthetics: Naturally, you want your building to look good, so you’ll need to consider how the roof looks. If you’ve got a great looking building, you don’t want the roof becoming an eyesore.
Installation costs: Cost is always a consideration, particularly when building property. You may be set on one type of roof, but if the installation cost is too much you may need to find other solutions.
Sustainability: Most builders and developers are now looking for sustainable solutions. Whether it’s products made from recycled materials, or manufacturing practices with a low carbon footprint, this may come into your thinking.
Warranty: As with any major purchase, consider the warranty when buying. You want to know that you’re protected if something goes wrong and it’s not your fault.
