Guides and insights on commercial flat roof restoration, silicone roof coatings, and roof cost decisions for building owners and facility managers.
How much deposit is normal on a commercial roof coating job, how progress payments and holdbacks work, and why final payment should wait for lien waivers and warranty paperwork.
Most flat-roof leaks start where the roof meets the wall. Here’s how parapets, wall flashings, coping and counterflashing are prepped before a silicone roof coating, and what to check in a bid.
Your building’s footprint isn’t the area you pay for. Parapets, curbs and penetrations typically add 5-15% to a coating bid. Here’s how roofs are measured and how to compare bids on the same number.
On an exposed-fastener metal roof, the screws cause most of the leaks — and they get fixed before any silicone goes on. Here’s how backed-out and stripped fasteners are replaced, how rust is treated, how every head gets sealed, and how much material that takes on a typical warehouse roof.
A core cut is a small sample cut through every layer of your roof before a silicone coating goes on. Here’s what it reveals — layer count, insulation type, trapped moisture, deck condition — how it’s patched, and why a coating warranty depends on it.
Before a silicone roof coating goes on, every seam on the roof gets its own treatment — and it’s where most coating failures start. Here’s how seams are handled on metal, TPO, EPDM and mod-bit roofs, what ‘three-course’ means, how much material it takes, and what to look for on your quote.
Roof coatings sold and applied in PA, NJ, DE, MD and Ohio fall under state VOC limits, typically 250 grams per liter for roof coatings. Here’s what that number means, why solvent-free high-solids silicone clears it easily, and the three VOC questions to ask before you sign a coating bid.
A silicone roof coating can keep or even earn a Class A fire rating, but the rating belongs to the whole roof assembly, not the pail. Here’s how UL 790 / ASTM E108 work, what changes the class, and what to hand your insurer before the crew starts.
Three coating bids on the same roof can differ by $70,000. Here are the 10 line items a silicone roof coating quote should show, the dry-mil math to check, and the red flags that hide change orders.
A new silicone roof that looks gray within a year is normal: silicone’s slightly tacky surface holds dust. Here’s what dirt pickup does (and doesn’t) do to performance, how to clean a silicone roof safely, and why the 3-year aged reflectance is the honest number.
