Your business roof does more than just cover your building — it protects everything inside, including your staff, customers, equipment, and products. But winter can be tough on roofs, especially if they already have problems. That’s why fixing your commercial roof before the cold weather hits is so important. Here are 14 reasons why you should check and repair your roof before winter.
1. Higher Energy Bills
Have your electricity or heating bills gone up recently without any change in how you use them? Your roof could be the reason. When it comes to roofing Maui homeowners should be aware that a damaged roof can let heat escape in winter or let heat in during summer. This means your heating and cooling system has to put in extra effort, leading to higher energy bills. A well-insulated and well-maintained roof helps keep your indoor temperatures steady and your energy bills lower.
2. Water Leaks Inside
If water drips from your ceiling or down the walls when it rains, that’s a big sign your roof needs fixing. Roofs are meant to stop water from getting inside. When they’re damaged, water can sneak in and cause mould, rot, or even damage the structure of your building. Look for stains on the walls or a musty smell — both could mean there’s moisture getting in through your roof.
3. Pooling Water on Flat Roofs
Flat roofs often collect some water, but they should dry up or drain off within a day or two. If water stays there, it’s called “ponding,” and that’s not good. Standing water can lead to leaks, mould, and faster roof damage — especially rubber or asphalt roofs. If you see puddles on your roof after rain, call an expert to inspect it.
4. Roof Sagging
Pooling water can also make parts of your roof sag. Roofs are supposed to be flat and sturdy. If one area looks lower or “dips” in, that means the weight of water has weakened it. This can be dangerous, and it needs to be fixed quickly to avoid more damage or even a collapse.
5. Blocked Gutters and Drains
Your building’s gutters and drains should carry rainwater away from the roof. If clogged, water may stay on the roof or leak inside. After a storm, check if water is coming out of your downspouts like it should. If not, you may have a blockage that needs cleaning or repair.
6. Cracks and Bubbles on the Roof
If you or a professional inspect the roof and see cracks, bubbles, or blisters, that usually means there’s air or moisture trapped under the roofing material. These spots are weak and could turn into leaks. If you notice any, call a roofing specialist.
7. Damaged Flashing
Flashing is the metal edging around vents, chimneys, and where different roof parts meet. It keeps water from slipping into cracks. If the flashing is bent, rusty, or missing, it can let in water and cause serious problems. Always fix flashing issues right away to avoid larger repair bills later.
8. Roof Rot
Roof rot happens when water sits on the roof too long and eats through the layers. You might notice sagging, water stains, dark spots, or cracks. This kind of damage weakens the whole roof and needs urgent repair. If you notice any signs of rot, contact a professional right away.
9. Wind Damage or Blow-Offs
Strong winds can tear off roofing materials — especially if they weren’t installed properly or worn out. If the seams of your roof aren’t sealed tightly, wind can get under them and rip them off. This is dangerous and expensive to fix, so it’s better to check for loose seams and damage before winter storms arrive.
10. Light Coming Through the Attic
If you can see daylight coming through your attic roof, that’s a clear signal you have holes or gaps. And if light can get in, so can water, cold air, and animals. Sometimes it’s just missing shingles, but other times it could mean the wood underneath is rotting. In either case, it’s best to call a roofing expert.
11. Missing or Damaged Shingles
If your commercial roof has shingles, check for any that are curling, broken, or missing. Missing shingles expose areas of your roof to the elements, which can result in water leaks and more severe issues. Damaged shingles typically indicate out, suggesting the need for roof repair or replacement.
12. Moss or Mold on the Roof
Moss and mould grow when water sits on the roof too long. They’re most common in shaded areas. A little moss isn’t a big deal, but large patches can trap moisture and lead to rot. If you brush off moss and see rotting underneath, your roof has already started to break down.
13. Animals in the Attic
If you hear noises in the attic or find signs of animals, like nests or droppings, they might enter through holes in your roof. Rats, birds, and critters sneak inside to stay warm during winter. Their presence not only signals roof damage but can also lead to other problems like chewed wires or insulation. Seal up those entry points before the cold sets in.
14. Your Roof Is Just Getting Old
Even the best roofs don’t last forever. Different materials have different lifespans:
- EPDM (Rubber): 10–15 years. Less costly but less durable.
- Modified Bitumen: 10–20 years. Multi-layered and heat-absorbing.
- Built-Up Roof (Tar & Gravel): 15–20 years. Very strong but heavy.
- PVC: Long-lasting and tough, but expensive.
- Silicone (Spray-On): Around 20 years. Seamless but pricey.
- Asphalt Shingles: About 20 years. More common in homes.
- TPO (Thermoplastic): Durable, energy-efficient, and affordable.
Conclusion
Winter weather is hard on commercial roofs. Ignoring early signs of damage can cause minor issues to grow into major, expensive problems. Before the snow and ice arrive, inspect your roof or hire a professional. Fixing problems now will save money, protect your building, and keep everyone inside safe.
