"Frank and Nick did an excellent job replacing a window, installing snow guards, and completed roof repairs to make the house weathertight for me. They showed up when they said, worked very efficiently and got everything done quickly. Pricing is very fair and quality workmanship. I have used F.B.I. a couple times now and know I will use them for future projects."

"I've been meaning to write this review for awhile now, but it's been difficult because I want to give an honest summary of our experiences - warts and all - while still being fair about the end result. TLDR: Yes, there were some difficulties, however Donna, Ricky, Tim, and the whole Southers team made sure they were acknowledged, fixed, and in the end we are thrilled with the results. You can teach a person skills or a new role, but what you can't do is teach someone to care. These people care about the work they do and they're willing to put in the time and effort and stick with it, until it's done right. That level of dedication is priceless. Now for the long version... Last July, after interviewing a number of companies, my husband and I decided to hire Southers to take on our house renovations. It was a big job. We needed a new roof, new siding, new gutters, twenty-six new windows, and two new external doors. All of this work also had to be coordinated with an asbestos abatement team to remove our old asbestos siding and our electrician who was replacing our meter and panel for the solar panels we plan to have installed. Donna was our salesperson and she worked with us every step of the way. She helped us decide on the best materials for our project, listened to our concerns about timing, and was incredibly responsive to any text or calls. Luckily, she happened to be promoted right as our project began work so she ended up being our contact through every aspect of our remodel. Yes, there were some missteps, which I will get into, but throughout it all Donna was there to help. I can't speak highly enough about her dedication and professionalism. Initially, we had a few other project managers assigned to our project. The first one ended up leaving the company early in the process. The second project manager was stationed fairly far away and wasn't as "hands on" as we would have hoped. Because of this, our building permit paperwork fell through the cracks which led to our project getting halted until the issue could be resolved. There were also some unnecessary miscommunication issues and one specific error of our external doors being ordered the incorrect size that lead to snowballing consequences. The first crew that Southers sent out to work on our home was fabulous. Pedro and his crew were punctual, professional, and precise. They were tasked to replace our windows, siding, and trim. They showed up every morning bright and early and ready to work. My husband is in construction. Every night, he would come home from work and look over what they had accomplished that day. Then, he would either confer with Pedro or leave me with notes to share with him in the morning. Not only was Pedro open and receptive to this level of communication, he welcomed it. I really appreciated his work ethic and attitude. I wish that I could say the same about the roofing crew. Because we are planning on installing solar panels, it was especially important that our roofing was done well. (Once the panels are installed, it's much more difficult to get any issues resolved.) We decided to use two different roofing materials. The majority of our roof would be asphalt, however we would have metal roofing installed on our back dormer. This was the most cost-effective way to get a new roof while still ensuring the solar panels didn't penetrate the roofing, thereby voiding our warranty. The roofing crew did an incredibly poor job on our roof. When my husband came home and inspected the work, he became increasingly upset, took photos, and contacted our project manager. We insisted that the asphalt roof get redone. Even then, there were some spots that had to be addressed. Our experience with this crew was so negative that when we were told they were also going to be installing our metal roof, we expressed our deep reservations. We were assured someone would be on site to ensure their work. Unfortunately, that didn't happen and the metal roof was also incorrectly installed. At that point, we were both upset. We invited Ricky to meet with us so that we could discuss the issues directly. To his credit, he came - along with Donna - listened to our concerns and frustrations, and committed to fixing the issues. Yes, the roof delayed progress on finishing our project, but I appreciate the fact that they stuck with it and got it done right. Ultimately, we got a good roof installed, but it took a lot of communication, frustration, and diligence on our part. In the end, our home looks fantastic! We knew this was going to be a large undertaking and that it would require a lot of time, effort, and patience. We expected there to be a few missteps along the way. However, it was worth it We now have a beautiful home that we can be proud of. If you have managed to read this far, I'll leave you with a few key lessons that I've learned during this project. 1. Make sure you have a permit to hang in your window before any work starts. 2. If your house is older than 1978, test for lead paint. Any estimates should include the cost of lead abatement. 3. Maintain open, active communication and don't be afraid to advocate for yourself. 4. Stay organized! Keep any/ all documentation and photos throughout the project."

"I needed them to get the job done by the 15th (or it was going to run into other very important things I had going on, so had them scheduled to start the job 4 days before this (in case they needed to rrepalce the roof boards with plywood). Well (because of another job they had) they showed-up on the 14th. This did cause me a headache as the job ran to the 16th. I was at the home doing other work when they started the job and I kept an eye on their work. When stripping the roof (of both the shingles and the wood boards, a lot of this rubble filled-up the brand-new soffet vent boxes I had built -my home did not have soffets/soffet vents or a ridge vent before I started my renovations). After stripping and dropping the chimney, one of the younger workers on the roof started to plywood the roof and I noticed he was installing the plywood over the top of the soffet vent (as they should), but without cleaning all the rubble out of them! This would mean the roof/attic would not vent propery (the air would not be able to go through these vents and up to the ridge vent (thus negating all my work of installing soffet vents and them installing a roof vent). I brought this to the attention of the younger worker on the roof (who's attitude was like, 'oh, ya'); Either he didn't know the importance of making sure the roof vented properly -which is unacceptable for a roofer- or he didn't care. I brought up my shop-vac and stood there while he vacuumed all the rubble out of the portion of the soffet he just covered (I had to go to work eventually and left the crew my shop-vac in the hopes they would vacuum out the rest as they went along -the older guy who ran the crew from the ground completely understood my concern about the rubble in the soffet vent and assured me the rest would be cleaned-out before they put the plywood over it (I do believe this was done because he was not too happy with the younger guy up on the roof for overlooking this -or getting caught overlooking this). The price was good for the work done (about mid-range in the quotes from other companies I had come by and look at the job -all from Angie's List). The job was completed in two days (so once stared, they moved pretty fast), and from what I watched them do: Installing about half the plywood, some of the the ice/water shield, shingles, etc, and the way it looks completed, it appears to be a solid job (and I've had no leaks to this point). And to their credit, they did comply with my on-job request to drop-in the plastic vents that run between the rafters (and connect the soffets to the ridge vent) on one half of the roof before they put the plywood down (this added about 15-20 min to the overall job -I could get these vents in on the other half of the roof myself from the attic). However, the fact that I had to catch the rubble in the soffets and that they didn't show-up when scheduled (and that I'm still chasing them down for a copy of the final invoice), I will not go with them when it's time to do the other side of the roof...or perhaps I will, if I can take the day of from work and 'supervise' the job"

"Went very well. Crew was here at 7 in AM and did not leave uintil 6 PM. Took 2 days to do job. Very professional, respected my property. Cleaned up job site completely. Dumpster was picked up next working day, as well as unused materials. Love this roof. What I liked was that payment was not due until job was completed, except for a small deposit to purchase the roofing material."

FAQs for natural slate roofing installation and replacement projects in Alton Bay, NH

A slate roof features thin tiles of natural stone installed over a solid deck and underlayment. Formed under intense heat and pressure, slate is exceptionally durable and delivers a distinctive, high-end look. Because the material weighs far more than asphalt, most homes need added structural support before installation. 

While upfront costs are higher and routine inspections are a must, many homeowners choose slate for its unmatched longevity and curb appeal.

Slate stands out for its 50- to 200-year life span, low maintenance, and classic aesthetic. It’s fire-resistant, energy-efficient, and often boosts resale value. 

On the flip side, slate runs far more per square foot than asphalt, weighs up to four times as much, and demands a contractor who specializes in the material. Tiles can crack on impact, and repairs cost more because the work is slow and precise. If your budget and structure can handle it, slate delivers top-tier performance for generations.

Natural and synthetic slate aim for a premium, stone-like appearance, whereas asphalt focuses on affordability. Real slate runs $10 to $30 per square foot installed and lasts up to 200 years; synthetic slate costs $10 to $15 and tops out at 50 to 100 years. 

Standard asphalt averages $3 to $8 per square foot and needs replacement every 20 to 30 years. If you want the slate look without the full price tag—or extra roof weight—synthetic is a solid middle ground.

With routine inspections and prompt repairs, a natural slate roof can last well beyond 100 years; some hard-slate installations reach the 200-year mark. Soft slate falls in the 50- to 125-year range, and synthetic products last 50 to 100 years. 

Remember, flashing, fasteners, and the underlying structure may need attention sooner than the stone itself. Severe hail or fallen limbs can also shorten life span, so schedule periodic checkups with a slate-qualified roofer.

If you plan to stay in your home long term—or want a standout selling point—slate delivers strong value. Although installation costs are high, owners often recoup 60% to 70% at resale and enjoy lower replacement cycles than asphalt. The stone’s durability, energy efficiency, and timeless curb appeal also appeal to eco-conscious buyers because fewer roofs end up in landfills. Just be sure your framing can handle the weight and that you budget for occasional specialty repairs.

Skip the DIY climb if you have a slate roof. Slate may be tough against the weather, but a single misplaced step can crack a tile and create a leak path. The surface also turns slick when wet, upping the risk of injury. Professional crews use staging and hook ladders that spread weight across multiple slates, protecting both the roof and the worker. To inspect or repair slate, call a roofer who specializes in the material.
