When should I replace my slate roof?

If more than 30% of your slate roof is damaged, it's time to consider a full replacement. This will prevent further deterioration and avoid costly recurring repairs. A professional slate inspection (costing between $130 and $360) can confirm whether repairs are sufficient or if a full roof replacement is the better option.

What is the expected lifespan of a slate roof?

A slate roof can last anywhere from 60 to 150 years, depending on factors like installation quality, regular maintenance and repairs, and local weather conditions. Compared to materials like clay and concrete, which often last around 50 years, a well-maintained slate roof offers superior longevity, durability, and long-lasting aesthetic appeal.

Can I perform temporary slate roof repairs?

Yes, you can use temporary patch solutions, such as roofing cement or patchwork, to provide immediate relief for minor leaks or underlayment issues observed from inside your home. However, these provisional fixes do not replace the need for a permanent, professional exterior repair, which is necessary to ensure the long-term integrity and weather resistance of your slate roof.

Roof4life Roofing Company Serving Homeowners in Seattle, Bothell, Everett, Tacoma, WA & All Other Surrounding Communities in the Puget Sound Region

"Geo came and gave me an estimate on 3 porch post and a beam and sent a contract that defined what needed to be done. Talked to the subcontractors who weren't aware of the conditions or wheather they needed to install post brackets or any other procedures. The subcontractors talked to me about the need to replace concrete surrounding post and I told them, yes replace. Later I reazlized they hadn't neither caulked nor replace necesary concrete. From what I saw, they probably used the wrong type of post brackets for my particular situation. Somebody from Roof4Life needs to check and verify project is done correctly before they let subcontractors leave. They are the experts not me."

"DO NOT EVER HIRE THIS COMPANY. 7 years ago they installed metal roofing on our new construction made with SIPS. Our contractor provided manufacturer installation instructions. Early work began fine and their process was signed off by our contractor. Then multiple crews came through, who apparently did not get the message. A metal roof on top of SIPS SHOULD HAVE LASTED 50 YEARS. NOW we're having to replace our roof at a greater cost than out-of-state college tuition. The new roofers are having to scrape rotted OSB from the foam insulation, completely negating the SIPS warranty and littering the neighborhood with the rotten debris. The analysis is that Forever Roofing (1) installed the Tiger Paw sheeting incorrectly and (2) did not bend the top of the metal panels up under the roof peak, both of which allowed water to enter. FURTHERMORE, after letting water in, they blocked off any egress at the bottom of the roof with wood blocks between the staves. Eventually water sat in there for years until the soffits started popping off. One of the Forever Roofing managers came by to take a look at the damage and essentially washed his hands of the business - no integrity for workmanship. RUN AWAY - "Forever" is an utter misnomer."
