The signs of a problem may be subtle. You might not notice until the leaks get so bad they make you afraid to go anywhere. Then you’ll suddenly remember that in the last few years, your roof has never stayed dry for long, even when it’s been raining. Or maybe you noticed that the last time you climbed onto the roof, you could see cracks in the tiles, but now they have completely filled with moss.
Your roof is probably not going to fall on your head or collapse or anything like that. But unless it’s maintained very well, it will eventually fail. Here we’ve discussed signs to watch out for hiring professional roof repair services.
Why Fix Your Roof Earlier?
One of the most frequent maintenance jobs is repairing roofs that are already damaged. Often roofers find that the leak is caused by a crack in a tile or a loose piece of flashing at the ridgeline where two pieces meet. If you don’t fix those things, more will follow. And once cracks start to appear, all kinds of things can happen. For example, you can have water leaks inside your house, ice dams form on your shingles, and leak into your attic. Besides, wind moves loose pieces and causes more damage. Rain slips through holes and creates damp patches on every horizontal surface — including your ceiling.
Let’s look at tell-tale signs of a damaged roof;
Signs to Look Out For
- Leaks
The first of the signs that you need to repair your roof is a leaky roof. A leaky roof will let the water drip off, and it’s hard to ignore that dripping. If you have a leaky roof, don’t wait until it rains again to fix it. Take care of it now. Leaks signify a more serious problem that you don’t even notice.
- Old roof
A roof that is old and worn down has a chance of breaking down or failing at any moment. This can be a huge problem, especially if it happens during the rainy season or when there is snow on the ground. If you notice that your roof looks raised or sagging, you should call in a professional right away. Read more about Why should you choose a family roofing company?
Is your roof more than 20 years old? If so, it’s probably time for a repair or replacement service. Age can be one of the most significant factors when it comes to determining whether your roof needs to be repaired or replaced.
- Missing shingles
A roof has many moving parts, and the most visible one is the shingles. If the shingles aren’t there, you can’t tell how well the roof is holding up.
If your shingles are missing, you should probably replace them. If they are not missing but look like they might have been removed, you should also replace them.
- Accumulation of mold and moss
The accumulation of mold and moss on your roof is not only unsightly, but it can actually be damaging to the structure of your roof. The moisture that gets trapped underneath the mold and moss encourages rot which will eventually cause structural damage.
Key Takeaway
A beautiful home can be achieved through maintaining the house and its components. One of the areas that often get ignored is the roof. Sometimes, you don’t have to wait until it starts leaking before doing something about it. If you see any of the signs above, you’ll know that your roof needs some work done on it.
How Long Should a Roof Last? Lifespan by Material
Roof lifespan depends on the material. Use the table below as a guide. Climate, installation quality, and maintenance also affect how long a roof lasts.
| Roof material | Typical lifespan |
|---|---|
| Asphalt shingles | 20 to 30 years |
| Metal roofing | 40 to 70 years |
| Clay or concrete tile | 50 years or more |
| Slate | 75 to 100 years |
| Wood shingles | 20 to 40 years |
If your roof is near the end of its lifespan, repairs may only delay the need for a replacement. A roofer can tell you whether a repair or a full replacement is the better choice. Ask for a written assessment. Check the warranty on your current roof. Some roofs carry a warranty of 20 to 50 years. A warranty may cover materials but not labour. Read the warranty papers before you pay for a repair.
Repair or Replace? How to Decide
Repair the roof if the damage is small and the roof is young. A few missing shingles, a small leak, or a loose flashing can be fixed. Replace the roof if the damage is widespread. If more than 30% of the roof is damaged, replacement is often cheaper in the long run. Replace the roof if it is old. A roof near the end of its lifespan will keep needing repairs. Replace the roof if the decking underneath is rotten or sagging. A sagging roof is a structural problem. Call a professional at once. Get three written quotes for both a repair and a replacement. Compare the costs. A repair may cost less now, but a replacement may save money over 10 years. Ask each roofer how long the repair will last. A good roofer will be honest about whether a repair is worth it.
What to Do When Your Roof Leaks Right Now
Move furniture and valuables away from the leak. Place a bucket under the drip. If water is pooling in the ceiling, poke a small hole in the bulge to let the water drain into the bucket. This stops the ceiling from collapsing. Turn off the electricity in the affected room if water is near lights or outlets. Do not climb onto a wet roof. Wet roofs are slippery and dangerous. Call a roofer for an emergency repair. A roofer can add a temporary tarp to stop the leak. A tarp is not a permanent fix. Schedule a proper repair as soon as the weather clears. Take photos of the damage for your insurance claim. Call your insurer and ask what the policy covers. Keep receipts for any emergency repairs.
How to Choose a Roof Repair Contractor
Check the contractor’s licence and insurance. Ask for proof. A licensed roofer with insurance protects you if something goes wrong. Ask for references from past customers. Read online reviews. Ask how long the company has been in business. Get three written quotes. Ask each roofer for the same scope of work so you can compare prices. Check the warranty on the repair. A good roofer offers a warranty of at least 1 to 5 years on the work. Never pay the full price upfront. A deposit of 10% to 30% is normal. Pay the rest when the job is done and you are happy with it. Walk around the house with the roofer after the job. Check that the shingles are in place and the flashing is sealed. Get the warranty papers before the roofer leaves.
