Roofs and Moisture
Roof Types on Minneapolis, MN Homes
Most Minneapolis roofs come down to two real choices: asphalt shingle or standing-seam metal, with slate turning up on older Kenwood and Lowry Hill homes built before shingle took over. Bungalows in Fulton and Longfellow usually carry shingle. What holds up under 51 inches of average snowfall matters more than what looks right.
The quick answer
Asphalt shingle covers most Minneapolis houses, from Kingfield bungalows to Tangletown foursquares, and holds up 20 to 25 years under Twin Cities winters. Standing-seam metal, seen on some Linden Hills and Prospect Park homes, sheds snow well and runs 40 to 50 years. Older slate turns up occasionally near Kenwood, often past 75 years.
Ice dams are the real cost of ownership here, not the install price. A shingle roof on a Tangletown foursquare with thin attic insulation will dam and back up water most winters. Metal sheds snow cleaner and resists that, but costs more upfront — a trade-off worth pricing out before deciding.
Questions & Answers
Frequently Asked Questions
Which roof covering lasts longest here?
Metal and composite outlast composition shingle by a wide margin, and both cost more up front. The honest comparison is not the warranty number on the wrapper but how the covering behaves in this climate: what holds moss, what sheds needles, what a low winter sun and forty inches of rain a year do to it. A thirty-year shingle and a thirty-year climate are two different things.
Can I put a different covering on than the one I have?
Usually, but not always without work underneath. Weight is the first question - concrete tile is several times heavier than shingle and the framing has to carry it. Pitch is the second: below about a 2:12 slope a shingle roof will not shed water and the roof has to be a membrane whatever it looks like from the street. An HOA may have a say in the third.
Does the covering change how often the roof needs looking at?
It changes what you are looking FOR. Composition shows its age as curling, cupping and granule loss. Metal shows it at the fasteners and the seams. Cedar shows it as splitting and cupping shakes with moss in the gaps. Tile rarely fails as tile at all - what fails is the underlayment beneath it, which is invisible until it leaks.
What is actually on most roofs around here?
Architectural composition shingle, by a long way, and it has been the default for new construction and re-roofs for decades. Cedar shake is on a good number of older houses and is usually replaced with composition or composite rather than renewed. Metal is a deliberate upgrade. Flat membrane turns up on a porch, a dormer or an addition rather than on a whole house.

Knowing what is on your roof now is the part most homeowners are unsure about, and it changes every answer that follows. A 1920s Whittier foursquare may be carrying two layers of shingle over board decking; a newer build near Plymouth may have laminate over plywood with a proper ice barrier already in. The covering, the layers under it and the deck they sit on decide whether a repair is sensible or a tear-off is overdue. The licensed pros we connect you with can tell you which you have.
