Can You Shingle a Flat Roof?
We always see asphalt shingles on traditional roofs but can you shingle a flat roof? It's a question we get a lot at Blue Sky Roofing, and the answer isn't just a simple yes or no.
Low-slope or Flat Roof?
First, let's clear up some terminology. "Flat roof" is a generalized phrase because few roofs are completely flat. To prevent water from sitting on your roof, builders design flat parts of a roof with a slight slope to shed water with the aid of gravity. These roof sections are called low-slope roofs.
Will Asphalt Shingles Work on a Flat Roof?
Most asphalt shingles are made to fit roofs with slopes. The shingles' overlapping pattern directs water away from the roof and downward. This design becomes a problem on a completely flat roof. Water can become trapped beneath the shingles, which might result in:
- Leaks: Standing water can seriously harm your house by leaking through the shingles.
- Premature Roof Failure: The shingles' lifespan may be greatly shortened by the continuous dampness, which might cause them to decay far more quickly than they would on a pitched roof.
- Voided warranties: If shingles are laid on a level or nearly flat roof, the majority of shingle manufacturers can cancel their warranties.
Always Consult with a Roofer!
If you're unsure which roofing material is suitable for your flat or low-slope roof, it's always best to consult with a qualified local roofing contractor like Blue Sky Roofing. We can assess your roof's particular needs and recommend the best, most durable roofing solution. We will consider factors including your building's construction, environment, and budget to help you make an informed decision.
Instead of shingles, consider these options for flat roofs:
- Modified bitumen is a long-lasting, multi-layered roofing material that works well on flat roofs.
- Thermoplastic olefin, or TPO, is a single-ply membrane roofing material that is renowned for its longevity and energy efficiency.
