"The entire process went very well. The team at JDH is excellent, from their sales guys, to on site managers, to individual workers. All are professional and courteous and take their time to do it right. We've had a few scheduling hic-ups throughout the process, but overall they've been excellent from start to finish. Most importantly, my new roof and skylights look top notch, and will last a lifetime!"

"They provided pictures of the holes in the roof beforehand.  Discussed what was going to be done.  At the time of work, it went very well.  The entire job took 2 days.  The crew was friendly and took the time to find my leak in the roof and repair everything to my standard.  No more leaks!

"Tony and EA roofing are great! I needed to have my roof replaced due to hail damage. Tony helped to facilitate the entire process for me and made everything as easy as can be. Their guys put on a great new roof using landmark pro materials. They were in and out in 1 day, cleaned everything up and left us with a beautiful new roof. I highly recommend EA roofing. Thanks Tony!"

"I am a senior with a background in construction.  After reviewing many contractors and speaking with some of them, I immediately knew I hit the jackpot when I spoke to Danny.
 
1.  He knew exactly what I needed and wanted done when I first spoke to him.  This entailed the replacement, repair, and installation of the items listed above with attention to quality in materials, prevention of future problems, a fair price, and a commitment to starting and showing up once the job was initiated.  Danny exceeded every expectation in these regards!
2.  I silently knew in advance manufacturers, quality and cost of exterior doors (including the french door), storm doors, door locks and deadbolts, leak-proof door sills for 6 inch exterior walls and a leak-proof barrier on the bottom of the door frames.  Without knowing of my preferences, Danny suggested the identical manufacturers and materials I had in mind.  At this juncture, we met and I hired Danny to perform the work.
3.  I am beyond pleased with the outcome of Danny's effort on this project.  As an example of his integrity, he asked me to trust him in the design and installation of an exterior octagonal window in a bathroom.  My wife and I were literally blown away with a handcrafted symmetrical waterproof tunnel and inside wall frame he created - more akin to an artistic piece than a window.
4. Inside work was always minimally invasive using tarps and soft shoes rather than work boots.  Outside and inside cleanup at the end of each work day was respectfully performed leaving no mess.
I would recommend Danny to anyone requiring any kind of interior or exterior installation, modification, or repair as I have seen firsthand examples of his experience, skills, and personal and business ethics.  In fact, Danny is presently working on costs to replace our roof."

"The company showed up on time and conducted the shingle replacement being careful not to damage the gardens around the house. They brought the roof up to current code, (the roof no longer complied with local codes), and worked with our chimney company to install the flashing properly. The cleanup was performed in an acceptable manner and the work was finished on time. Follow-up inspections by the company and I showed I had a good roof that was going to last another long time. I would definitely recommend this company for roof work."

"Very well. Siding is immaculate. These folks thoroughly saturated all siding surfaces with a heated hypochlorite (dilute bleach) solution. Waited for the solution to take effect, and then rinsed off completely. They also cleared our skylights when asked, at no additional cost."

"Hammer and Nail contacted me within 10 minutes of my submission of an online request  for information. That right off the bat impressed me as two other contractors I contacted prior to Hammer and Nail never contacted me back even after I left them voice messages. Hammer and Nails sales rep Nikos came to my home and showed and explained to me all of my product choices and then spent a significant amount of time measuring and remeasuring the monster size door to be replaced.  Prior to my door order being submitted, another Hammer and Nail employee came to re-measure and confirm the original measurements. Due to the size of the door (and double screen doors) and transom it was pretty much a custom built door and it did take about 6 weeks for the door to be delivered from the Marvin factory but I was informed by Nikos that that would be the case and I had no objections to the time frame. Once the door arrived, the construction staff quickly scheduled installation. James and his install crews showed up exactly on time. James and his crew were very courteous and took great measures to protect my floors before demolition of the existing door. The guys did an excellent job of installing the new doors and transom. James himself made sure that the screen doors latched properly and that the doors were aligned perfectly. The crew used spray float insulation instead of cramming in little pieces of fiberglass insulation. The crew did a great job caulking the walls inside and out and cleaned up after themselves before they left. I am so pleased by this experience with Hammer and Nail that I will be calling them in the near future to replace my basement door.

FAQs for natural slate roofing repair projects in Clements, MD

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.
