Slate roofing is one of the most durable and attractive roofing materials available today. It is also not the cheapest material, however, so it it important to understand that having a leak in your slate roof does nor necessarily mean that you have to fully replace it.

LGC Roofing offers slate roof repairs to our NJ customers. We do everything we can to reclaim slates that are in good condition and only replace those that cannot be reused.
Slate Roofing Repair Process:
- First we evaluate the problem. We check whether you have any slates missing or damaged, whether the flashing and valleys are in good shape and if the roof is reparable or not.
- After inspection is done we will provide you written estimate of the work that needs to be performed, the price details and warranty period information.
- In order to start working we then install special setup that prevents us from walking directly on slates.
- To replace missing or broken slates we have to remove old nails using special tool called slate rippe. We then remove all pieces of broken slate, install slate hook and hang new slate.
- If we need to change flashing or valley, all slates around it need to be taken off, new flashing put into place than the same slates are installed.
