A commercial roof leak rarely announces itself with a neat drip directly under the problem. More often, you’ll see ceiling stains that appear days after a storm, damp insulation that spreads well beyond the entry point, or a “mystery” leak that comes and goes with wind direction and temperature swings. The good news: most commercial […]
Great roofing isn’t only about installing a system correctly. It’s also about what happens after installation — the responsiveness, the follow-through, and the way a contractor handles service when a building owner needs help. That’s why we’re proud to share that Commonwealth Roofing Corp. was awarded a Duro-Last A+ Service Award for 2026. The Duro-Last […]
Hailstorms get attention when the hailstones are large enough to rattle windows and dent cars. But roof damage isn’t limited to “golf ball hail” events. Smaller hail can still harm roofing materials in subtle ways, leading to leaks that grow over time. Whether the storm dropped quarter-sized stones or pea-sized pellets, understanding what hail does […]
Leaks rarely show up directly under the hole. Water can travel surprising distances, following the path of least resistance — across the deck flutes, around insulation joints, along structural members — before you even realize there is a leak. That’s why “find the wet spot, patch above it” often turns into repeated service calls. Leak […]
Ice damming is one of the most damaging winter roofing issues because it creates a simple problem with expensive consequences: water that cannot drain normally will find another path. When snow melts and refreezes in the wrong places, ice can form a “dam” that traps water on the roof. That trapped water can back up […]
When you own or manage a commercial building, “roof coatings” can sound like a miracle fix — minimal tear-off, less disruption, lower cost and a fresh white surface that helps with energy bills. But you have probably also heard horror stories about coatings peeling, blistering or trapping moisture. So are roof coatings actually worth it? […]
When a commercial roof starts leaking, you have two clocks running at the same time — how fast the water is spreading, and how fast you can respond. In those first 24 hours, the choices you make will decide whether you are dealing with a manageable incident or a major interruption that damages equipment, inventory […]
If you own or manage a building, winter doesn’t just bring cold weather—it brings freeze-thaw cycles. That back-and-forth swing above and below freezing is one of the most common (and most overlooked) causes of roof deterioration. The tricky part is that freeze-thaw damage often starts small and quiet—a tiny opening at a seam, a hairline […]
When a metal roof starts leaking, many owners assume there are only two choices — keep patching or rip everything off and start over. Both options sound painful. One keeps draining your maintenance budget with call after call; the other feels like a major project that disrupts your schedule and ties up cash. There is […]
12‑Month Commercial Roof Care Plan — Prevent Big Bills Don’t let your commercial roof care plan start when something goes wrong — a drip over a production line, a stained ceiling in the lobby, a wet electrical panel. By that point, a small, inexpensive repair has often turned into a big, disruptive bill. A simple […]
