For many commercial buildings, the roof is one of the biggest untapped opportunities for energy savings. It sits in direct sun, covers a huge surface area, and plays a major role in how much heat enters or escapes the building. Yet a lot of owners only think about the roof when there is a leak. […]
When something seems wrong with your commercial roof, one of the first questions that comes to mind is simple: Do I need a repair, or is it time for a full replacement? That question matters because the wrong decision can cost you. Repairing a roof that is already failing across multiple areas may only delay […]
Choosing a commercial roofing contractor is a major decision. Your roof protects your building, equipment, employees, tenants, and day-to-day operations. It is also a significant investment, which means the contractor you hire can affect everything from roof performance to long-term costs. A low price may look appealing at first, but the cheapest proposal is not […]
In many cases, yes — a roof coating can restore a commercial roof and help delay a full replacement. But there is an important qualifier: the roof still has to be in good enough condition to restore. If the system is structurally sound and the problems are mostly surface-level, a coating may be a smart […]
Geese may not be the first thing building owners think about when considering commercial roof damage, but they can create real problems over time. On many commercial properties, especially those near retention ponds, lakes, open fields, and landscaped office parks, geese are more than a nuisance. They can affect roof cleanliness, drainage, maintenance access, and […]
If you own or manage a commercial building, one of the most common questions you will ask is simple: How long does a commercial roof last? It is an important question because your roof protects your building, inventory, equipment, tenants, and daily operations. It also represents a major capital asset, so understanding its expected lifespan […]
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 […]
