Guides and insights on commercial flat roof restoration, silicone roof coatings, and roof cost decisions for building owners and facility managers.
Silicone roof coating jobs typically run 1.5-2 gallons per square per coat across two coats, but gallons are just a proxy for dry mil thickness, the number that actually determines your warranty length. Here’s how to do the coverage math and sanity-check a contractor’s quote.
A silicone roof coating’s 20-year warranty depends entirely on how it’s installed. Here are the five application mistakes that most often void it.
Every legitimate silicone roof coating warranty starts with an infrared moisture scan of the existing roof, not the coating itself. Here’s what that scan checks for, the 25% wet-insulation threshold that decides coat-vs-replace, and why skipping it is the fastest way to void a 20-year warranty before it’s even issued.
High-solids silicone roof coatings are low-odor and low-VOC compared to solvent-based alternatives, which is why they’re routinely applied over occupied hospitals, schools, offices, and warehouses. Here’s what ventilation, HVAC intake management, and VOC compliance actually look like on an occupied commercial roof.
A silicone roof coating is warrantied for 10, 15, or 20 years based on mil thickness, and recoating at the end of that term renews the warranty for another cycle. Here’s how the recoat schedule works and what maintenance keeps you from doing it early.
Yes, you can coat a commercial metal roof with silicone. Here is what it costs ($3-6/sq ft vs $10-16 to replace), why metal roofs leak, and when coating is the right call.
A silicone warehouse roof coating runs $3–6/sq ft installed vs $10–16 for a tear-off — 50–70% less, no downtime, 20-year warranty. Cost, energy savings, and what to expect in 2026.
The best time to coat a commercial roof is late spring through early fall, when surface temperatures stay above ~50°F and the roof stays dry long enough to cure. Here’s why temperature beats the calendar—and why timing is a job for a pro.
Can you write off a commercial roof coating on this year’s taxes? Often yes — when it’s treated as a repair. Here’s the plain-English breakdown of repair vs. capital improvement, Section 179, and the documentation that protects your deduction.
Most commercial flat roofs — TPO, EPDM, and modified bitumen alike — can be restored with a silicone coating instead of torn off and replaced. Here is what qualifies each membrane type, what disqualifies it, and how to tell which category your roof is in.
