"I needed a small repair, due to a less than stellar original install (unknown contractor) when the home was built. Paragon came out in a timely manner and repaired the roof quickly and professionally. I plan to use them this summer when I contract for the roof replacement. Very satisfied with their work."

"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 got 4 quotes for a roof replacement and ultimately chose Southers Construction for the customer service and reasonable price. During the free estimate, Ricky was the only one to take out a ladder and climb on to the roof to take a look at everything and determine what needed to be done as part of the project. He was very knowledgeable and explained to me what they would fix, how, and why. He also gave me pricing options for some of the additional things I wanted done as part of the overall roof replacement (better airflow using soffits vs roof vents). The team did a great job, I'm very pleased with their work and they did it in one day. They draped the house / bushes to protect them while they worked. They also cleaned up the yard / driveway after they were finished. I didn't find one nail after they were done. I will definitely be calling them back for other projects and highly recommend them."

"I was originally told by another company that the gutter needed to be replaced and after discussing the problem with New England Gutter Systems they were able to fix the issues and clean the gutter for hundreds less than a replacement would have cost. They were very prompt and friendly making all the needed repairs quickly after speaking with them. It would have been easy for them to just go with my initial thought of a new gutter but made sure they solved the issues without that added unnecessary expense."

"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"

"Team arrived earlier than expected, and easily finished the whole roof in the day. One week later and still haven't found any debris larger than a quarter in the yard, and no nails. I got compliments on the new roof less than an hour after it was installed."

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.
