Q: 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.

Q: 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.

Q: 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.

"5-star ratings do not come easy. Eric responded to my request to replace the roof on my shed. Not a big job but it needed to be done. He came out, never tried to upsell me on anything, gave me an outstanding price, performed the work, did a super job, they check off all the boxes in my book. Would use them again in a heartbeat. I did get other estimates which it would have been cheaper for me to just replace the shed. Thanks Eric greatly appreciated. Eric took care of his crew on a hot day, another box checked off on my list."

"The job went well. The crew that done the job did a very good job. Over all I was pleased with every thing that was done. The only thing I had a problem with was the price of the job. I was quoted one price and before they would do the job I had to ok an extra $4,000 before it could be done because they under estimated how much materials it would take for the job. Other than that I was very pleased."

American Remodeling is a family-owned and operated company that offers windows, roofing, siding, bathrooms, kitchens, basements and sunrooms. We are one of the few Platinum Preferred roofing contractors by Owens Corning in PA. We offer 100% financing to fit most budgets.

"We sadly signed up for a free estimate. Jon came on 8/16 and we were told by Jon a few times all we had to do was call in within 3 days and get our deposit back. I asked twice and my husband asked once he said "all we have to do is call and we will get our $100 back" Clearly not true. I called on the 3rd day 8/19 and spoke with a lady, i thought her name was gabby, but apparently they lied giving me that name she doesnt work there. I have no idea what her name was sadly I did not record the call. Was told my papers weren't put in it was no issue, my check would be mailed on Monday the next business day. Well a week later I get a call from financing stating they need signatures. Confused I was like we canceled and you all were supposedly mailing my check. Well low and behold apparently you can't cancel over the phone. So Jon lied multiple times and "gabby" lied when I called in. They cashed out check and our free estimate cost us $100. I was told the VP would call us back on 8/26. He finally called us on 8/29. We missed the call but called right back. Have tried calling today 8/30. When I called to cancel the service it was within my time period! Of course now it's out. Lesson learned! Don't trust them! When I called on 8/19 at 3:24pm the call lasted under 2 minutes, which it was very quick. Told them I needed to cancel an epoxy job, transferred me to some girl, I told her jon said all I had to do was call. she said up and went on about the papers not being filed yet and since it was friday and late the check wouldn't be mailed till monday. Never again."
