Rambler Roof Replacement — Low-Slope Single-Story Roofs Done Right
You own a 1950s to 1970s rambler with a low, wide roof, the shingles are going, and you want it done in a day by someone who knows what a shallow pitch and a deep overhang do in a Minnesota winter.
Rambler roof replacement is a low-pitch, single-story job with long eaves: easy to walk, fast to tear off, and the eaves are where it has to be right, because a shallow slope sheds slowly and the ice dam sits on a deep overhang. JMB Builders runs wide ice and water shield at the eaves, opens the soffit intake, cuts in a ridge vent and shingles it, across the Twin Cities metro. Priced per project; most ramblers take one day.
- Low pitch: wide eave membrane, often several rows
- Soffit intake opened, ridge vent cut in
- Most ramblers: one day on site

The rambler is the easiest house in the metro to reroof and the easiest one to reroof badly. Everything is in reach: one story, a pitch you can walk, a simple gable or hip, few penetrations. A crew can tear it off and shingle it in a day. The trouble is at the edges. A low slope sheds water slowly, so wind-driven rain and backed-up meltwater travel farther up under the shingles than they would on a steep roof. The overhangs are deep, which puts the cold eave a long way out from the heated wall, and that is exactly where an ice dam forms.
So the ice and water shield band at the eave on a rambler is wide. The Minnesota code measures it from the inside face of the wall below, and on a low pitch with a deep overhang that line is well up the slope, often several rows of membrane rather than one. Shingles on the shallowest ramblers may also need the manufacturer's low-slope install, with membrane under the whole field and the courses lapped tighter. We check the pitch at the estimate and write the scope to match it.
The other rambler problem is the attic. Long, low attics have a lot of floor and very little height, the soffit vents are often painted shut or stuffed with insulation, and many were built with a few box vents and no ridge vent at all. Hot in summer, frost on the nails in winter, ice at the eaves. With the roof open we cut a ridge slot the full length, open the soffit intake and close off the old box vents, and we look at the insulation while we are up there.
What you supply
- Photos of the roof from each side of the yard, a close one at the eave edge, and the attic underside if you can get in
- Your shingle choice from samples at the free in-home estimate
- Driveway space for the dumpster; cars and grills out from under the eaves on the day
- A note about any room where the ceiling has stained or the eave ices up
What JMB supplies
- Pitch measured at the estimate so the eave membrane width and any low-slope shingle method are set before the order
- Tear-off to the deck, decking replaced where soft and quoted per sheet, dumpster and magnet sweep
- Ice and water shield at the eaves to the Minnesota code coverage from the wall line, in valleys and at every penetration
- Synthetic underlayment, new drip edge at eaves and rakes, new pipe boots and bath fan caps
- Ridge vent cut in the full length, box vents removed and decked over, soffit intake opened
- Architectural shingles with matching hip-and-ridge, the city's permit and inspection, finished photos in your job folder
How it is priced: per project
Quoted in writing from your photos, with a reply within one business day. What moves the number:
- Squares: ramblers are wide, so the footprint is most of the roof area
- Pitch: the shallower the roof, the more rows of eave membrane and possibly a low-slope shingle method
- Layers coming off; many ramblers carry a second layer from the 1980s or 1990s
- Decking: 1950s and 1960s plank decks that need an overlay vs. later plywood
- Hip roof vs. gable: hips add ridge cap and cutting
- Ventilation work: ridge slot, soffit intake, box vents closed
- Attached garage roof included in the same tear-off
- Gutters replaced at the same time on the long eaves
A photo straight on at the eave edge shows us the layers and the overhang depth. The pitch is measured at the estimate.
How long it takes
Most ramblers, including the attached garage: one day on site, tear-off in the morning and shingles done by evening. A second layer or a plank deck can push it into a second morning.

Situations and options
Gable rambler
Two long slopes, one ridge, two rakes. The simplest roof to shingle. The ridge vent runs the full length and the two long eaves carry the wide membrane band.
Hip rambler
Four slopes meeting at a short ridge. More cutting at the hips, more ridge cap, and the short ridge limits how much exhaust a ridge vent can give, so intake and exhaust get balanced carefully.
Very low pitch rambler
Some 1960s ramblers sit near the bottom of the pitch shingles are rated for. Those get membrane under the whole field and the manufacturer's low-slope method. Below that pitch, the roof needs a membrane system instead of shingles.
Rambler with a walk-out
The back eave over a walk-out basement is a full two stories off the ground. Same roof, but the dumpster and ladders work from the front and the back eave is staged from below.
Rambler Roof Replacement — Low-Slope Single-Story Roofs Done Right: questions, answered
Why does a rambler need more ice and water shield at the eaves?
Because the code measures the membrane from the inside face of the heated wall, and on a low pitch with a deep overhang that point is a long way up the slope. The cold eave is where snowmelt refreezes into a dam, and on a shallow roof the water behind it backs up farther. On many ramblers that works out to several rows of membrane instead of one. We measure the overhang and the pitch at the estimate and the scope lists the width.
Can a rambler roof be replaced in one day?
Most of them, yes, including an attached garage. One story, a walkable pitch and a simple shape mean tear-off is done by midday and the roof is dried in and shingled by evening. A second layer of old shingles, a plank deck that needs an overlay, or rain in the forecast can push the shingles into a second morning. The roof is never left open overnight either way.
Is my rambler roof too flat for shingles?
Shingle makers set a minimum pitch for a standard install and a lower minimum with membrane under the whole field and a tighter lap. Most ramblers are above the first line. A few 1960s roofs sit between the two and get the low-slope method. Below the second line, shingles are not allowed and the roof needs a membrane system. We measure the pitch at the estimate and tell you which case you are in.
Should I add a ridge vent to my rambler when I reroof?
Yes, if the attic has or can have soffit intake. Most ramblers have box vents and painted-shut soffit vents, which is why the attic cooks in summer and frosts in winter. We cut a ridge slot the full length, remove the box vents and deck over the holes, and open the soffit intake so the ridge vent has air to pull. On a hip roof with a short ridge we balance intake to the exhaust the ridge can give.
Does the attached garage roof get done at the same time?
It should. On most ramblers the garage roof is part of the same roof or ties into it, and the valley or wall where they meet is a leak point that gets new flashing when both are open. Doing the garage later means disturbing that joint twice. It is listed as its own squares on the scope so you can see the cost.
Should I replace the gutters on my rambler with the roof?
If they are sagging, seamed, undersized or pulling off the fascia, yes; a rambler's eaves are long and the gutters catch a lot of roof per foot. New drip edge goes on with the roof, and new gutters hang on it cleanly. If the gutters are sound we take them down where needed and rehang them. Either way it is its own line on the scope.
