Not every roof is a simple sloped field of asphalt shingles. Some Michigan homes call for the natural character of cedar shake, and many homes and commercial buildings have flat or low-slope sections that need an entirely different system. Both require specialized knowledge to install and maintain correctly. Here is how each one works and where it fits.
Cedar shake roofing
Cedar shake brings a warm, textured, natural look that no asphalt shingle fully reproduces. It suits certain architectural styles beautifully and, when properly maintained, can last for decades. Cedar is a living material, though, so it needs the right underlayment, proper spacing for airflow, and periodic maintenance to resist moisture, moss, and rot in our climate.
Distinctive, high-end natural appearance with real depth and dimension.
Good durability and insulating character when installed and maintained correctly.
Requires proper ventilation beneath the shakes and ongoing care to reach its full life.
Best installed by a crew experienced with natural wood roofing details.
Flat and low-slope roof systems
Flat roofs are not truly flat. They have a slight slope to move water toward drains, and because that slope is shallow, they rely on a continuous membrane rather than overlapping shingles. These systems are common on porches, additions, dormers, and commercial buildings. The most common modern option is TPO, a single-ply membrane that is energy efficient and resists weather and UV well.
TPO single-ply membrane: durable, reflective, and energy efficient.
Designed as a continuous, sealed surface that sheds water toward drains.
Flashing and seam detailing are critical, since a low slope gives water more time to find a weakness.
Well suited to additions, porches, and commercial or mixed roof lines.
Why specialized installation matters
Both cedar shake and flat roofing punish shortcuts. Cedar needs correct spacing and ventilation to dry between rain and snow, and a flat membrane is only as good as its seams and flashings. These are not systems to hand to a general crew. They reward experience, careful detailing, and the right materials for the Michigan climate.
Matching the system to your home
The right choice depends on your architecture, the slope of each roof section, your goals, and your budget. Many homes use more than one system, with shingles on the main slopes and a membrane over a flat porch or addition. The key is having a contractor who installs all of them and can recommend the right product for each part of your roof.
