Before & After: Flat Roof Replacement in Glen Allen, VA

Can you spot the before-and-after difference?

We replaced the flat roof for this Glen Allen home earlier this month. Flat roofs are a common roofing option throughout Richmond, whether for a whole home or on small additions with low pitches. The two main types of flat residential roofs are modified bitumen and single-ply.


Modified bitumen roofs have an estimated lifespan of 15 to 20 years. The main drawback to modified bitumen is its more-intensive – and therefore expensive – installation process, with multiple applications and skilled labor required to properly install.


Meanwhile, a single-ply  roof – like this Dec-Tec roof, or TPO – can last between 20 and 30 years, and it has an easy installation and cleanup process.


The main disadvantage of any flat roof is any puncture or tear, such as from a piercing tree limb, could threaten the entire structure.

How often you need to replace your home's siding depends on the material, but most siding products last about 30-50 years before needing replacement.
