Roofing Material & Underlayment
What is the best underlayment to use before installing a new roof?
Synthetic underlayment is widely considered the best choice because it offers superior tear resistance, moisture protection, and durability during installation. In Massachusetts, combining synthetic underlayment with an ice-and-water shield along eaves, valleys, and penetrations ensures maximum protection against ice dams and wind-driven rain.

How long do different roofing materials last?
- Three-tab shingles: 15–20 years
- Architectural shingles: 25–30+ years
- Metal roofing: 40–70 years
- Rubber and membrane systems: 25–35 years
Is it cheaper to put a metal roof or shingles?
What is the difference between 20-year and 30-year shingles?
Twenty-year shingles are thin, basic three-tab materials designed for budget-focused installations. Thirty-year shingles, also called architectural shingles, are thicker, more durable, and provide better wind resistance, longer warranties, and enhanced curb appeal. Architectural shingles are preferred in Massachusetts because they better withstand snow and storm conditions.

What Our Clients Are Saying
Posted on Kyle CarnaseTrustindex verifies that the original source of the review is Google. Manny and his team did an excellent job doing the siding on my house. It was a quick and professional job, and I'm happy with the results. Manny went above and beyond by generously taking a trash pile from an unrelated job for free despite my offer to pay him!Posted on Joseph RodinTrustindex verifies that the original source of the review is Google. Excellent work from GN Exteriors, house looks incredible! Kept it the same color as before but went from cedar shakes to vinyl. Super professional crew that worked very efficiently. Great price, quick turn around, clean. A+ all around.Posted on Aayush SethTrustindex verifies that the original source of the review is Google. I got quotes from six roofing companies and ended up choosing this one — and I’m so glad I did. Manny was great from the start: knowledgeable, easy to talk to, and quick to earn my trust. He answered all my questions, hit everything on my list, and made the process simple. They replaced the entire roof and skylights in one day. Manny was on-site the whole time, making sure the job was done right. They even improved the ridge vent for better airflow and left the property spotless. Lastly, they came right on the initial quote. Overall, they were professional, efficient, reasonably priced and very easy to work with. Highly recommend!Posted on Christine LaskarisTrustindex verifies that the original source of the review is Google. GN Exteriors was the lowest priced yet superior quality contractor. Manny and his team were professional and accommodating throughout the entire project. I highly recommend them!!Posted on Peter WallaceTrustindex verifies that the original source of the review is Google. When the gutter on my mom's house fell due to rot, I called Manny at GN Exteriors because they did a great job on my house two years ago. They checked on the damage and sent a proposal right away that was detailed and reasonably priced. Within one business day of receiving the deposit, the job was done and done very well. Communicating with Manny is easy as he responds quickly and is always professional. I would recommend GN Exteriors to anyone looking to improve or repair their homes.Posted on Han LiTrustindex verifies that the original source of the review is Google. We recently had our roof and gutters replaced by GN Exteriors, and they did a fantastic job. Manny, the owner, was exceptionally professional and responsive. He explained everything in detail about the work to be done and how it would be carried out. He promptly responded to our questions, and we never felt any pressure from him. His team was incredibly efficient, completing our entire roof and gutters in just one day. Manny returned the next day to inspect their work, shared with us the pictures of the new roof he took with a drone, and ensured we were satisfied with the project. He stands behind his work, and even when we found something that didn't look quite right, he sent someone over immediately to take care of it. He made sure we were 100% satisfied. If our home needs work in the future, we'll definitely choose Manny and his team again. We won't hesitate to recommend GN Exteriors to anyone.Posted on Chris BurbulTrustindex verifies that the original source of the review is Google. Manny and his crew replaced a very deteriorated shingle roof on a small building on our property. Manny was friendly and professional when he bid the project. His crew worked hard and did excellent work. They stripped the roof and we inspected the damage under the shingles together and he quickly brought in the additional materials that we agreed were necessary to make sure that the job was done right. When the job ran a little over time due to the unforeseen need to replace more sheathing that we anticipated, Manny brought the crew back early the next morning to finish up before some oncoming rain. I recommend Manny and his team. I would hire them again.Posted on Kevin LoftusTrustindex verifies that the original source of the review is Google. Great communication, fair price, quick turnaround, and excellent work!Posted on Kevin KastTrustindex verifies that the original source of the review is Google. We have recently dealt with many contractors on many projects, and Manny and his team are the best of the bunch! They were professional, responsive to my many questions, reliable, and skilled, and heroically flexible when the other contractors working on related things kept delaying their project. We hired them to replace our siding, and they guided us through our options and delivered everything as promised. Highly recommended!Posted on Chris JenningsTrustindex verifies that the original source of the review is Google. The owner Manny was an awesome. He was prompt, professional and friendly. His team was the same and were a pleasure to deal with. They also went over the top and on a section of hardy board on my house they painted it to match. I highly recommend them.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
