"I really appreciated working with Diamond Ridge to replace my roof. They gave me a lot of confidence that they would do a great job and would take care of my needs. Marcelo was a wonderful project manager. When he came to look at my property and assess my roofing issues, he took his time to understand my concerns and make sure the issues I had were from the roof and not another source. If I have friends getting their roofs replaced, I will definitely recommend Diamond Ridge and Marcelo for the job."

"The roofing and reconstruction work carried out by Lifetime Roofing & Renovation on two structures on my property was outstanding in every way possible. One of the structures is architecturally unique and the other one is over a hundred years old, so both demanded thoughtful planning and careful roofing and construction. From the very start, Marcelo, the project manager, was superb and on the job, helping us to understand each step of the project. All communication with Marcelo and the crew was excellent and timely as we looked at possible roofing solutions and reviewed the range of roofing materials. The roofing materials shown to us and those selected were of outstanding quality and with good prices too. I was particularly impressed by the careful planning process and this attention to detail; and also the ease of involving the owner, myself, from beginning to end. On both projects the timing of every phase was excellently coordinated, skillfully and smoothly completed."

Natural slate roofing repairs FAQs

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.

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.

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.
