"The process went well. The men showed up on time and got the job done quickly and very professionally. They cleaned up very well before they left. The men were very respectful of our house and yard as they completed their work. I will use them again to clean the chimney and keep our unit in great shape and safe."

"Tim was timely, thorough, and honest about the state of my chimney and work that needed to be done. He was very professional, but down to earth and easy to work with. I have worked with him in the past, and know that he is meticulous with his inspection and trust his professional guidance with the work that needs to be done. I highly recommend Top Shelf Chimney. I will be using them again for the repairs and for future inspections."

Customers say: True professional

"Wow! Amazing service. I must've called 8 different places in a panic trying to get the brick mounts which hold the mantel removed from my old fireplace so the surface could be prepped for a new TV. Seemed like an easy task (I thought), but it was a little more meticulous than I thought. I called this team and they arrived same day! Incredible customer service and expertise. Not only did they return the day after providing an estimate and remove the brick mounts, they actually re-fabricated the brick to make the holes disappear! This team knows their stuff!! I was so impressed that in the Spring I'd like them to come and do some masonry work for me. Highly recommend. They really are committed to doing good work and meeting the needs of their customer Special thanks for seeing to my issue before my TV install. We are ready for the Superbowl!!"

"They were great. They had a cancellation and came the next day to close our damper and cleaned the chimney at the same time and only charged us for the cleaning. Then they fit us in a week later to seal a crack at the chimney top. They gave us before and after pics of everything. They were punctual, professional and experienced and I recommend them highly to anyone looking for chimney services."

"The project choices above did not match the actual project -- which was to inspect and then clean my wood-burning prefab fireplace. Logan did an excellent job, and I've referred him and the company to two of my neighbors. He also helped me understand the scope of the work as well as other work that the condo association needs to consider. it was also important in case the condo association questions my choice of vendor, that he has the appropriate certification from the Chimney Safety Institute of America"

Chimney Inspection FAQs, answered by experts

While a few icicles on your roof are standard, a large accumulation can be a sign of a bigger problem, such as poor insulation. This is particularly true if you are also dealing with ice dams. If you have numerous large icicles, it is recommended to have a roofing contractor diagnose potential insulation issues and create a plan to solve them.

There is a weight limit for walking on a roof, but it’s determined by your roof structure and not the roofing material, at least in the case of a metal roof. Consider that entire teams of roofers will be on top of your home during the installation, so the weight of a single person won’t compromise your roof. That isn’t the case for something like a tile roof, so a high weight limit is one benefit of a metal roof.

There should be small gaps between your roof and the walls of your home, and other buildings. These small gaps let building materials shift, expand, and contract with weather and other outside forces, and they prevent moisture from wicking down walls from roofing and gutter systems. Without these strategic gaps, your home’s exterior and its finishes can sustain water damage, decay, peel, delaminate, and crack. However, there is a fine line between a smart gap and a problematic gap—all  gaps should be small, intentional, and covered or filled in with foam insulation to prevent pests from using them as access points.

Patching a rubber roof requires finding a leak that is most likely identified by inspecting the attic. Get a strong flashlight and inspect the underside of the roof. Look for mold, wet spots, or dark, discolored areas. Check for degrading insulation, which tends to break down faster than wood. Inspect vents and seals and keep an eye out for small punctures coming through. The leak could actually be several feet away from where you find the water damage because of how water flows or gets diverted. In dry weather, spray the roof with a hose while someone else watches for leaks inside the attic. 

The most common defect in a flat roof is leaking. Flat roofs have minimal slope, so water pools more readily on a flat roof than on a sloped roof, and the risk of the waterproof membrane failing increases with exposure. Tears and punctures from foot traffic and blown debris are other common problems, especially with single-ply roofing membranes like TPO and EPDM roofs.
