Over time, the steel nails will rust and eventually break, allowing slates to become dislodged.

Where Does Slate Come From Return To Top

Slate is a fine grained, crystalline rock derived from sediments of clay and fine silt which were deposited on ancient sea bottoms. Superimposed materials gradually consolidated the sedimentary particles into bedded deposits of shale. Mountain building forces subsequently folded, crumpled, and compressed the shale. At the same time, intense heat and pressure changed the original clays into new minerals such as mica, chlorite, and quartz. By such mechanical and chemical processes bedded clays were transformed, or metamorphosed, into slate, whole geologic ages being consumed in the process. Slates vary in composition, structure, and durability because the degree to which their determinant minerals have been altered is neither uniform nor consistent.

The adaptation of slate for roofing purposes is inextricably linked to its genesis. The manufacturing processes of nature have endowed slate with certain commercially amenable properties which have had a profound influence on the methods by which slate is quarried and fabricated, as well as its suitability for use as a roofing tile.

The Replacement Of Deteriorated Roofs Return To Top

Historic slate roofs should be repaired rather than replaced whenever possible. Before replacing a slate roof, check for isolated damage, corroded and worn flashings, leaky gutters, poor ventilation in the attic, and other possible sources of moisture. All too often slate roofs are mistakenly replaced when, in fact, they could have been effectively repaired. Deciding whether an historic slate roof should be repaired or replaced can be difficult and each roof must be judged separately.

If repair is not possible and a new slate roof must be installed, it is important to remember that more than just the replacement of the slate is involved. The old slate should be removed to prevent overloading of the roof timbers. Stripping should be done in sections, with felt installed, to avoid exposing the entire subroof to the weather. ln the process, rotted wood sheathing should be replaced and the roof timbers checked for signs of stress including deflection, cracking, and twisting. If such conditions are found, a structural engineer experienced in working with older buildings should be consulted. Other repairs, such as chimney repointing, which may require access to the roof should be completed before the new roof is put on.

How To Calculate For Roofing Materials Cost

When youre getting a roofing job done, the first step is to calculate how much material costs are going to be so you can get an idea on what your total project cost will be.

To do this, take the length of your house and multiply it by its width for example, if your house has 100 feet in one direction and 50 in the other, that would be 500 square feet.

Multiply that by how much it costs per square foot of material and then add labor fees on top of it for example, if your roof needs to be covered with asphalt shingles and they cost $15 a square foot, you would multiply 500 sq ft x 15 dollars which equals $7500.

If the roof needs to be done with metal shingles, multiply 500 sq ft x $20 and you would get $10000 adding labor fees on top of it.

Hopefully, this gives an idea about how much a 1500 sq ft roof replacement is going to cost in your region.

The material costs will depend on what type of roofing material your home needs, while labor fees are going to be determined by the steepness of your roof.

Does The Roofing Company Provide Maintenance As Needed What Kind Of Maintenance Is Required

If you have full or partial slate roofing on your property, it is important to choose a company that will offer maintenance work, if needed, should problems arise. Maintenance work will often be covered under warranty with the roofing company. However, each company has different policies, so the length of the warranty and the types of issues that are covered will depend on which company does your roofing.

Slate, in general, requires little or no maintenance because the stone does not rust, warp or attract mold. As such, a slate roof is unlikely to be damaged by usual weather conditions or natural events short of an earthquake or a tornado. That said, slate tiles can crack if you walk on them. Therefore, it is best to avoid walking on a slate rooftop for any reason. Trim nearby tree branches, so they don’t land on the rooftop. If your cat likes to climb up walls, don’t let it out of your sight when you let it roam outdoors.

When problems do arise with slate shingles, the issue is typically down to tiles with face nails, on which the fastener gets exposed over time to rainfall, snow and water buildup, which can lead to rusty nails that ultimately fail to hold the shingles.
