Columbia, MO Flat & Low-Slope Roofing — Residential & Commercial

Columbia MO Roof Pros provides professional flat & low-slope roofing in Columbia, MO for residential and commercial properties across Boone County and mid-Missouri. The low-slope roofs in Columbia are mostly small: a rear kitchen addition, a porch roof, a flat-topped dormer on a house near campus. They are also where most of the leaks are, because the details at the wall are harder than anything on the pitched field above them.

Slope is the first thing to check. A porch roof that ponds after every rain has either settled or was never built with fall in it, and no membrane fixes standing water for long. Where the framing allows, tapered insulation or a rebuilt deck to establish real drainage is money better spent than a thicker membrane laid over a flat pond. Ponding water finds every seam eventually, and it has all year to do it.

On occupied buildings we specify cold-applied and self-adhered SBS modified bitumen rather than torch-applied. Open flame on a wood-framed porch attached to a house full of tenants buys nothing and risks a great deal. Self-adhered goes down clean, bonds to the base sheet, and keeps a torch away from a hundred-year-old soffit. Insurers have firm opinions about torch work on occupied residential buildings as well.

The termination at the wall decides whether the job lasts. Membrane has to turn up the wall and go behind the siding, or into a reglet under counterflashing, rather than stopping at the siding line beneath a bead of sealant. Almost every low-slope leak we open in the campus-area houses comes back to a termination that was caulked instead of flashed. Sealant is a maintenance item that has been asked to do a flashing detail's job.

Single-ply has its place on larger decks. Mechanically attached sixty-mil TPO over polyisocyanurate works on flat-roofed apartment blocks and small commercial buildings, and the seams weld rather than merely bond. On a two-hundred-square-foot porch it is the wrong tool, and buying it there is commercial pricing for a residential detail. The system should be chosen for the size of the deck, not from a brochure.

Drainage off a low-slope roof also has to end somewhere. A scupper dumping against a wall, or a downspout that stops at the foundation, produces exactly the dampness in the wall that the property maintenance code names. We finish the water path rather than only the membrane, and that is usually where the last stretch of the job sits. Water that leaves the roof correctly and then soaks a wall has solved nothing.

Our licensed and insured team brings the right materials and equipment to every job — self-adhered ice barrier turned two feet inside the heated wall line, hemmed 26-gauge drip edge lapped over a gutter apron, hot-dipped galvanized step flashing woven course by course, coil-wrapped fascia over primed and sound sub-fascia, vented soffit panels sized to the existing overhang, six-inch K-style seamless gutter carried on hidden hangers — and backs the work with a written workmanship warranty. We serve Columbia and nearby communities including Ashland, Centralia, Hallsville, Sturgeon.

What We Handle

Why Columbia Chooses Columbia MO Roof Pros

• ✓We ask when your certificate of compliance expires before we quote, because the renewal date shapes the schedule more than the weather does
• ✓Every report is written against the property maintenance code sections an inspector actually cites, section by section, rather than as a sales sheet
• ✓A code correction and a storm loss are kept in separate documents, because a violation notice is not a claim and presenting it as one gets it denied
• ✓We will tell you to delete a skylight or take a dead chimney below the roofline instead of selling the replacement, where that ends a repeat finding for good
