"We couldn't be happier with Dave's overhaul of our fireplace. His attention to detail, and commitment to excellence. We feel so lucky to have found him after another contractor flaked out on us. He came to the rescue & did whatever it took to get the job done on time and on budget. He is highly skilled and capable. Several times during the job he suggested things that would enhance the finished product. In doing so he created more work for himself. These upgrades probably added a full day of additional work. He didn't change the cost for the job, he just wants his customers to be happy. His attention to detail and cleanliness blew our minds. He spent a full day getting the room taped off to prevent dust from spreading throughout the house. A full day!?!? And it paid off when the work was done...we're not even hiring a cleaner. More than anything Dave's got a good heart, my wife and I genuinely enjoyed meeting and working with him. (Note: no AI was used in writing this review!)"

Did you know that it's unwise to spend too much but it's worse to spend too little? How do you choose the right contractor? First, they should listen to what you want to have done, then they should take a look at what needs to be done. Our certified expert will provide a full inspection of the problem areas. We will take digital photos of these areas, and provide a complete color coded plan so that you can see what we saw. IN EXCHANGE FOR OUR TIME AND EFFORTS, ALL THAT WE ASK IN RETURN IS THAT ANYONE WHO WOULD HAVE INPUT BE PRESENT TO DISCUSS YOUR OPTIONS. We believe that this approach provides everyone with the best way to make a good informed decision. If you agree, please call us now. You'll be glad you did! Since 1969, GF Sprague has worked with discerning homeowners who buy the right job at the right price.

"I had a small leak. Sprague quickly diagnosed the need for a very expensive roof repair. I also had a skylight that was dripping and decided to replace a group of four skylights. The work was spread out over a longer time than anticipated, which Sprague said was due to unusually wet weather. As far as I can tell as an amateur looking up at the roof from a distance, the quality is good but only some winters with no leaks will confirm that. They put some rather conspicuous shiny white concrete in one small part of a strip of gray concrete but said it would eventually weather to the same color. The substantial problem came over the skylights. My existing skylights came with retractable shades for those summer days when sun shining through the skylights could be blistering hot. During the initial conversations, we focused on whether we would be able to use the old shades or would have to replace them. When the job was done, there were no shades and they were emphatic that the shades were not included despite our detailed conversations about them. The wood just inside the skylights had been replaced and needed to be overlain with higher quality wood and painted. I had assumed, based on our conversation, particularly about the shades, that doing these things was part of the job. But I didn't explicitly write the shades into the contract. Regarding the wood, they pointed to a sentence deep within the many pages of the document that left me responsible for any inside work. I had seen that but never imagined that the wood they used would have to be covered up with higher quality wood before it could be painted. I was quite surprised, particularly when I found out that this residual work, requiring a carpenter, a painter and a shades specialist, would cost several thousand dollars. I felt stupid to have relied so heavily on the conversation and to have signed off on something that only a professional would understand. In the future I would recommend having a specialist lawyer review any contract. It would have been much more professional of them to clarify at the beginning how much would remain to be done after they finished what they understood to be the job. Finally, a small thing: They didn't clean up carefully. Left in the yard were things like a roll of what looked like insulation, thirteen pounds of copper nails (I weighed them), and other stuff. I didn't feel comfortable throwing all those copper nails in the trash, so they sit in my garage pending possible donation to some workman standing outside Home Depot on my next trip there. Because of a previous experience with Sprague, I made a point of asking them to be sure to take away the advertising signs they had placed in my yard; they promised they would, but they didn't."

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.
