When natural materials make sense
Grand Rapids has thousands of homes built before 1939. Many have steep roofs, wide eaves, and craftsman details. Cedar and slate match that character. Asphalt can look flat on those homes.
Natural materials cost more and need more care. They suit owners who plan to keep a home for many years and who want the original look.
Cedar shake and shingle
Cedar gives warm color and texture. It ages to a soft silver-gray. A good cedar roof can last 20 to 30 years with care.
- Fire rating. Untreated cedar burns. Fire-retardant treatment can raise the rating. Ask for the product's class in writing.
- Airflow. Cedar needs air under it to dry. Many crews add a vented spacer layer.
- Upkeep. Moss and debris hold moisture. Clean the roof and trim nearby branches.
- Grade. Premium grades have fewer knots and cracks. They cost more and last longer.
The Cedar Shake and Shingle Bureau sets grading standards and install guidance for cedar roofs.
Natural slate
Slate is among the longest-lasting roofing materials. A well-built slate roof can pass 75 years. Many old slate roofs outlast the nails that hold them. Copper nails and quality flashing make a big difference.
- Weight. Slate weighs several times as much as asphalt. A roofer or engineer must check the framing first.
- Skill. Slate takes special tools and training. Not every crew can install it.
- Repairs. Slate is repairable, but walking on it can crack tiles. Plan access with care.
- Alternatives. Synthetic slate gives a similar look at lower weight and cost. Quality varies by brand.
Check the house before you pick
We look at four things before we quote natural roofing.
- Rafter size and spacing, to carry the load.
- Deck type. Plank decks suit slate and cedar when sound.
- Attic airflow, to keep cedar dry.
- Flashing design at chimneys, valleys, and walls.
Historic district rules
Heritage Hill alone holds roughly 1,300 historic properties. Exterior changes in historic districts may need city review. Roofing material is one of the changes reviewers look at. Contact the City of Grand Rapids before you order materials. We can help gather product samples and photos for your application.
Cost and lifespan
Cedar and slate both cost more than asphalt shingles. Slate usually costs the most. Labor skill, roof shape, and flashing work add to the price. Get a written quote that lists material grade, thickness, nail type, and flashing metal. Our cost guide explains how to compare quotes.
Not sure natural roofing fits? Many owners pick architectural asphalt in a slate or cedar tone. It gives a similar look at a lower cost. Or consider a metal tile roof.
Common questions
How long does a cedar roof last?
Most last 20 to 30 years with regular cleaning. Climate, shade, and airflow change that number.
How long does a slate roof last?
A well-built slate roof can last 75 years or more. Nails and flashing often wear out before the slate does.
Does my house need extra framing for slate?
Often it needs a check. Slate weighs several times as much as asphalt. Have a roofer or engineer review the framing.
Do I need approval in a historic district?
You may. Call the City of Grand Rapids before you order materials. Rules depend on your district and the work.
