The Alex Schmidt team was efficient and worked quickly to clean down spouts, roof and deck. The deck cleaned up beautifully. The estimated two-day job was done in six hours. It was expensive! The only reason I didn't give 5 stars is the windows were left with debris from the cleaning, the white trim should have been washed off as it was left dirty from the cleaning, and at least one of the down spouts was left dirty. I expected this would have all been done.

We asked Johnny and crew to come out to clean our roof, gutters and siding. The quote was for a couple thousand. We also asked for our shed roof to be cleaned. We read and reviewed their work on their website and it looked like they did a decent job. They came out promptly with little wait time so that was a plus. However, the one man crew missed the whole front section by our front door for cleaning the siding. He then totally missed doing the shed on the work order. The siding looks decent but if you are expecting every spec of dirt and old marks to be off, nope that won’t be the case. The photo of the dirty windowsill is my front porch area. That was taken after the second time they came out. If it is more work than pointing a pressure washer it won’t get cleaned. We had the same employee also come back and rinse whatever solution he used off our windows as it left a filmy residue that made my large windows look the worst I’ve ever seen. Customer service tried to tell us the shed roof had been cleaned the first time but i recommended reviewing your cameras because we sent receipts it wasn’t. Then when it was redone it might as well have not been done because it still looks the same, no ladder, no broom were used. Just a swish of the hose over the top of the roof and wow it doesn’t look any better. Also your hoses won’t be rebooked back up after so make sure you check those after. I pay for convenience and this ended up as a headache I could have done without. People say you get what you pay for but we paid a lot and this was not the same results as we have had before hiring a simple handyman to do that same job.

Did a great job. Moss on garage roof was really bad.
House roof looks brand new.
Workers were polite. I wish they could have picked up more of the moss on the one side of garage.
The only complaint I have is they forgot to close gate. Lucky I checked before letting out the dog. They were not the first service person to leave gate open, so I always check

The cost to replace the roof of a commercial building typically ranges from $5 to $12 per square foot, depending on several factors such as roof size, material, labor rates, building type, and local code requirements.
Several factors influence roof repair cost, including the extent of the damage, roof accessibility, material type, labor costs, and whether it’s a general repair or an emergency fix. Minor repairs can start around $150–$400, while major repairs may exceed $1,500.

Mobile home roof replacement cost typically ranges from $3,000 to $8,000, making it generally more affordable than traditional home roof replacements, due to smaller size and simpler structure.
It's not necessary to stay home during roof replacement. Roofing work is noisy and can cause vibrations inside the house, which might be uncomfortable. Most homeowners choose to leave during major parts of the project, but our team ensures safety and keeps you updated, whether you're home or not.
The timeline for a roof replacement typically ranges from one to three days, depending on the size and complexity of the roof, weather conditions, and material type. Larger or more intricate roofs may take a bit longer, but we always aim for efficient, timely completion.
To hire a roofing contractor, start by researching local companies with good reviews and proper licensing. Request quotes from multiple contractors, verify their insurance and certifications, and ask for references. Always ensure you get a written contract that outlines the scope of work, timeline, and payment terms.
Check if a roofing company is legit by verifying their business license, insurance, and local certifications. Look for memberships in professional associations, read customer reviews, and ask for recent project references. A legitimate company will be transparent and provide all documentation upon request.
When choosing a roofing company, consider their experience, customer reviews, warranty offerings, and quality of materials. Make sure they provide clear communication, detailed estimates, and a solid portfolio of completed projects. Local expertise is also a major advantage for understanding regional roofing needs.
Warning signs that your roofing contractor might be ripping you off include vague contracts, pressure to pay large upfront deposits, lack of proper documentation, and unexplained price increases. Always ask for itemized estimates and written guarantees, and avoid contractors who avoid answering your questions directly.
