Cedar Rapids Roof Pros provides professional flat & low-slope roofing in Cedar Rapids, IA for residential and commercial properties across the Cedar Rapids metro. Low slope on a house here is almost never the main roof. It is a porch, a back addition, a shed dormer, or the flat deck above a bay. It is also the part storm scopes skipped most often, because it is small and it is a different product.
That skipping has consequences we are still opening up. A crew paid by the square to reshingle a steep roof frequently ran the laminate straight down onto a two-in-twelve porch, where asphalt shingles sit outside their listing however carefully they are laid. From two up to four in twelve the listing calls for a doubled underlayment, and that step gets left out constantly. Shingle manufacturers publish that limit and it is not negotiable.
So pitch gets measured with a level and a rule before we quote, and a fair number of the addition leaks we open turn out to be laminate laid at one and a half. Sunrooms and enclosed porches added in the 1990s are the most common offenders in this metro, followed by garages with a shallow single plane. Neither of those was ever going to be kept dry by shingles.
On a house we use either a self-adhered modified bitumen build-up or a TPO membrane fixed mechanically, terminated into a rigid bar where it runs into a wall, with a detailed transition up into the shingle field above. Laps are heat-welded and then probed with a seam tool. Rolled roofing torched down over an old layer is what we usually arrive to strip off. Fasteners land in a seam plate, never through the open field.
Nothing on a low slope survives standing water. Tapered insulation or sistered sleepers move it toward a real outlet, a quarter inch of fall to the foot at minimum, and the drain or scupper goes where water actually collects rather than wherever the original builder found it easy to frame. If a puddle is still there two days later, that is a design problem and no amount of maintenance fixes it.
Where we push back is on replacing a sound membrane. EPDM and modified bitumen in good condition, with intact laps and no wet insulation under a core cut, do not need pulling off because the shingles above them are being redone. We will cut a core and show you what is in there before anybody spends money on that decision. That answer loses us a line item and keeps a sound roof on the building.
Our licensed and insured team brings the right materials and equipment to every job — nail-line placement read through a lifted tab, ice barrier carried 24 inches inside the exterior wall line, hip and ridge cap rated to the field shingle's wind class, two-piece counter-flashing set into a saw-cut reglet, continuous ridge slot confirmed from the attic side, synthetic underlayment capped-nailed rather than staple-fixed — and backs the work with a written workmanship warranty. We serve Cedar Rapids and nearby communities including Marion, Hiawatha, Robins, Fairfax.

Materials, equipment and how we do flat & low-slope roofing
The difference between flat & low-slope roofing that lasts and flat & low-slope roofing that gets redone in three years is almost always preparation and materials, not the finish you see on day one. We work with nail-line placement read through a lifted tab, ice barrier carried 24 inches inside the exterior wall line, hip and ridge cap rated to the field shingle's wind class, two-piece counter-flashing set into a saw-cut reglet, spec them to the job instead of to the invoice, and write the material grades into the free estimate so you know exactly what you are buying.
Every Cedar Rapids job runs the same way: site walk and measurements, written scope and fixed price, protection of the surrounding area, then the work itself with a daily clean-up. Years of roofing work in the Cedar Rapids metro means we have already met whatever your property is going to throw at us — awkward access, older construction, an HOA with opinions.

Why Cedar Rapids Chooses Cedar Rapids Roof Pros
- ✓We do not have to guess the age of your roof, because this city already knows it. What an inspection here establishes is who laid the covering and how fast, and that is a different set of findings
- ✓The nail line, the starter course, the cap product and the ridge slot are checked and photographed on every visit, because those four are where a rushed catastrophe install shows itself first
- ✓Reused flashing is called out by name in the proposal. Old metal with old holes in it, put back under new shingles, is the defect we find most and the one nobody else writes down
- ✓We ask whether your manufacturer warranty was registered in your name before we quote you a repair, even though the answer sometimes means we do not get paid for the work
