7 Signs you need to replace a Slate Roof

There are a lot of benefits to choosing slate roof tiles. However, much like any other kind of roofing system, they deprecate in value due to the daily wear and tear. If you’re wondering how to decide whether your slate roof tile needs replacement, we’re here to walk you through the process.

 If you can find these during your visual inspection, then it’s time to call in the experts.

Moisture damage

One of the first few signs to watch out for is moisture damage. During your visual inspection, observe the inside of your attic if there are any damp surfaces. Slate roofing is heavy, so if there’s moisture, this needs to be addressed immediately, so it does not affect the rest of your home.

Broken shingles

It is without a doubt that slate roofing systems are very durable. However, it’s still susceptible to damage, much like other roofing materials. If your shingles are exposed to blunt force damage, this may cause them to be brittle. In this case, there’s a need to replace every single broken shingle.


Another sign that you should call in the professionals like Country Roofing is if there’s rust. Your flashing protects your roof from water damage. If your flashing is rusted, then it would not be able to withstand water or moisture damage. Replace this as soon as possible so you can protect your home from all types of weather.

Slates sliding off or Missing, and out of place

 Due to the daily wear and tear, these slates may slide off one day. While many homeowners think they can replace these by themselves, it’s still advisable to call GenSun Roofing.


Stemming from water and moisture damage, you may notice leaks or damp formations in your attic. If this is the case, then some of your tiles may be damaged. Damage like this should be addressed quickly because it can spread from one single slate to larger sections of your roof.


Rotting parts

The quality of work done on your slate roof should be done by a professional so as to avoid additional costs and accidents. As for rotting parts and tiles suffering from flaking, you should consider removing the tiles that have been affected at least until professional roofers arrive. Depending on the condition, they can either replace it or use a sealer material.


If there are signs of efflorescence, then you should call GenSun Roofing for help. Note that efflorescence can lead to the formation of a type of coating on the surface of your roof. This powdery coating can be the result of excessive moisture.
