What is the cost of a slate roof

Slate is a natural stone that has been used for roofing for centuries. While the initial cost of slate roofing can be higher than other materials, its long-term durability and low maintenance costs make it an excellent value.

The following are warning signs that a roof collapse may be imminent:

1. Leaking: Water infiltration can weaken the structural integrity of a roof and lead to collapse.

2. Exterior cracks: cracks in the exterior of a building can indicate that the roof is not adequately supported and may collapse.

3. Bends in the roof structure, frames or support: any deformities in the roof structure can put the roof at risk of collapse.

4. Jamming or loose windows and doors: if windows and doors are not properly secured, they can become loose and allow the roof to collapse.

5. Interior cracks on the walls, ceiling, and around window/door frames: cracks on the interior of a building can indicate that the roof is not properly supported and may collapse.

6. Noticeable “sagging” of the roof: if the roof appears to be sagging, it is at risk of collapse.
