What Causes A Slate Roof To Leak?

Occasionally, bad weather might cause tiles or slates to fall off, exposing the roof’s underlayment. The likelihood of a leak growing results from significant rainfall pooling there.

The same can occur when slates or tiles chip or crack. It can also happen if the underlayment is rotted or when the flashing and drain pipes are damaged.

Another cause of leaks is ice forming along the edge of each slate. This happens when snow and heavy precipitation get on a roof but then melt due to warm weather.

The melted water freezes as it hits cold slate edges, possibly causing it to chip or crack and possibly causing an entire slate to become dislodged. This can’t be prevented, but it can be easily repaired.

What Is Headlap On A Slate Roof?

The “head” refers to the topmost top of the slate. Overlapping refers to the placement of one slate over another. Pretty basic. The crucial overlap on a slate roof occurs when the head of a slate overlaps the slate two courses above it.

The overlapping area has mortar applied to it, which expands and contracts with variations in temperature. This expansion and contraction do not affect the roofing tiles or slates when the roof is properly made.

Can You Jet Wash The Slate Roof?

What Is The Correct Procedure To Replace A Broken Roof Slate?

A proper slate repair includes the following steps:

  1. Remove the hidden nails that are holding the damaged slate in place.

Typically, there are two nails on each side of the damaged slate.

  1. Obtain a replacement slate that is the correct size.

Slates should be twenty-three inches long if the exposure is ten inches. Slates twice the exposure plus a three-inch margin for the head lap are used in a suitable slate application.

  1. Slide the slate into position, then mark the placement of a single holding nail in the gap between the sides of the above-course slates.
  2. The nail hole is punched into the slate from the rear, with the ragged section of the hole on the slate’s front or face. As a result, the nail will sit flat in the hole. It is a primitive sort of counter-sinking.
  3. Use a copper nail to secure the replacement slate in place. To pass between the sides of the two slates in the upper covering course, the edges of the nail head must sometimes be chopped off.
