"Working with Tom and James, Brian, Nick, and Tom was a pleasure! Tom came to my house, masked (due to COVID19) and sold me the window.His price was very reasonable and within the realms of other quotations I had received. The time frame he set for the installation was within days of the actual work being done. His workmen were fast, (window was installed in 2 hrs!) extremely courteous, and Clean!!!! I am VERY pleased with my new window! I would Highly recommend this company."

"I was surprised because it was during some of the worst winter weather but they were able to measure and install in a very short period of time. The material was cut to fit on site and was the color and quality I ordered. They did an excelletn job"

"This is the second job Summit Peak has done for us, and we are very pleased with all aspects of his work. He always responds in a timely manner when we contact him. He was very prompt to come and give us an estimate, and the work was started and finished on the dates we were told it would be. Everything was cleaned up properly, too. No complaints at all about quality or service with this provider."

"We needed a new roof . We interviewed 3 roofing companies and got quotes from each. After the interviews and reviewing the quotes we decided we were most comfortable with Jesse. We couldn’t be happier with our decision. The job was finished in 2 days and was done exactly as promised. We have experienced 2 downpours since the job was finished and no leaks. We are very comfortable in giving a positive recommendation and a 5 star rating."

"Brett Smith, owner, had quoted us a price to remove roofing and install new.  He estimated there might be a few pieces of plywood sheeting that need replacing.  As the removal of the shingles and underlayment took place, it was evident there were bigger problems than first anticipated, through no fault of the contractor.  Prior to accepting his bid, he informed us there may be more bad sheets than anticipated, and there was no way to be sure until the old roofing was removed. The old roof was only 10 years old, and as Smitty and his workers removed the roofing, it was evident the previous contractor ripped us off big time.  He was suppose to replace old sheeting, and only replaced a few sheets (the previous roofer).  Brett and I discovered nearly 25 plywood sheets that needed replaced due to rotting (previous roofer did not vent the roof either)!
Brett & I had agreed to extra pricing for this prior to him starting the job.  Obviously, you don't know what you can't see. Brett got me on the roof so I could see the damage, and I was in disbelief what the previous roofer had done to us.  The current job had been estimated to take 3 days, but because of all the hidden problems (bad sheeting, some broken rafters, bowed rafters) it took he and his crew 4 days.  Only one extra day for all that extra work!  They worked dawn to dusk, and I mean worked.  They did not fool around at all, which impressed me more than anything. He has a great crew! I was kept informed throughout the entire process, and they were very professional and courteous.
Smitty installed architectural shingles, properly vented the roof, and did many other extra things to insure the roof would be solid, aesthetic, and built to last a long time.  To say I am happy with the finished job is really an understatement.  My wife is very happy too, and that says a lot, trust me!  I did not know Brett Smith before he stopped by to give me an estimate, but I took a chance based on my feelings about his character after going over the estimate. I had also seen his work on a neighbor's house.  We had gotten three estimates for the roofing job, and Smitty's estimate was best by far.
I recommend Smitty's Roofing and General Contracting to anyone considering them for a contract.  Brett Smith is up front, honest, and keeps you informed. He does good work, is prompt, and has the best prices."

FAQs for natural slate roofing repair projects in Williamsport, PA

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.
