It typically comes down to roof slope, drainage design, rooftop equipment/penetrations, building use, budget, and your long-term plan (owning vs. holding). A site inspection plus goals-based recommendations makes the decision clearer.

A coating is generally a restoration approach applied over a suitable existing roof system to extend service life and improve performance, when conditions allow. Replacement involves removing and rebuilding more of the roofing assembly and is typically chosen when the roof is worn out or moisture issues are widespread.

Yes. Preventive maintenance helps reduce surprise leaks, catches small issues early, and supports longer roof life, especially on low-slope systems with drains, seams, and rooftop equipment.

A common best practice is regular inspections, especially after major storms and before/after harsh seasonal weather. (Exact frequency depends on roof type, age, and building conditions.)

Typically: checking membrane/seams, flashing, roof penetrations, drains/scuppers/gutters, roof edges/termination points, rooftop unit curbs, visible damage, and signs of ponding or moisture entry.

Recurring leaks, interior staining, ponding water, membrane blisters/splits, loose flashing, clogged drains, rising energy bills, and visible wear around rooftop units are common red flags.

Yes, Schultheis Roofing is a member of the National Roofing Contractors Association (NRCA).

Low-slope roofing is a watertight system that depends on membranes, seams, flashing details, and proper drainage, small failures can create big issues. Steep-slope roofing is designed to shed water quickly and typically relies on different materials and detailing. Both require specialized installation methods, but the risk points and performance factors are different.
