The Last Roof You'll Ever Install

Natural slate roofing is in a category of its own. Quarried from the earth, each slate tile is unique, and when properly installed, a slate roof will outlast the home beneath it. Many historic Seattle homes still have original slate roofs well over a century old.

Slate requires a skilled, experienced hand. It's heavier than other materials, so we conduct a structural assessment before any slate installation. Proper installation means each tile is properly lapped, fastened with the right nails, and detailed with copper or lead flashing at every penetration.

If you're investing in slate, you're investing in the finest roofing material available. Vantek brings the same precision and care to every slate job that the material demands.

FAQ

Slate Roofing Questions

Slate is a long-term investment that requires the right knowledge upfront. Here are the most common questions we hear before a slate project.

Full FAQ
How much does slate roofing cost? +
Natural slate installs in the King County area typically range from $35,000 to $80,000 or more for a standard home depending on slate type, source country, and roof complexity. Synthetic slate alternatives are available at a lower price point and offer comparable aesthetics with a more straightforward installation. We will walk you through both options during the estimate.
How long does slate roofing last? +
Natural slate can last 75 to over 150 years when properly installed and maintained. The slate itself rarely fails. Most slate roof failures are due to the underlayment or flashing deteriorating over time, which can be replaced without touching the slate tiles. This is what makes natural slate such a compelling long-term investment.
Can my home's structure support a slate roof? +
Natural slate is significantly heavier than asphalt or metal and requires a structurally sound roof system. We inspect the framing and decking before every slate project to confirm the structure can handle the load. In many cases minor reinforcement is all that is needed, and we account for this in the estimate. We will not proceed with a project that the structure cannot safely support.
How much maintenance does a slate roof require? +
Slate itself requires very little maintenance. The most common item is replacing individual broken or slipped tiles, which can typically be done without disturbing the surrounding roof. We recommend a professional inspection every ten to fifteen years to check the flashing and any mortar work on ridges and hips, which tend to deteriorate before the slate itself.
Do you repair existing slate roofs or only do new installs? +
We do both. Slate repair requires specific experience because working on a slate roof incorrectly can break the surrounding tiles. Our crew sources matching slate for repairs so the finished result blends with the existing roof. If your slate is otherwise in good shape, repairing it is almost always more cost-effective than a full replacement.
