& No money down, No payments, No interest for 1 year*


Authentic wood-shake character and a classic coastal profile — rated to 200 mph and engineered to never need paint or stain.
Few siding profiles carry the sense of place a wood shake does — the staggered, hand-hewn texture that defines cape, cottage, and coastal homes. Portsmouth Shake captures that look in UV-stabilized polymer, delivering the dimensional depth and warm character of natural wood shake without the splitting, rotting, and endless refinishing that real cedar demands.
TIMEPROOFUSA installs Portsmouth Shake as a complete exterior for homeowners who want classic shake character paired with the toughest storm rating in our siding lineup. Every installation is completed by certified TIMEPROOFUSA crews and held to our TimeLock standard.
The Choices Built Into Every Portsmouth Shake Installation
Shake-and-Shingle Profiles
Portsmouth Shake offers the dimensional texture of natural wood shake alongside a finer shingle profile, so you can match the scale and character your home calls for. Its classic lines work across a full-home application or as a textured accent on gables, dormers, and upper stories paired with another profile below.
Choose Your Color
Portsmouth Shake comes in a range of colors with the finish carried through the material rather than coated on the surface. Because the color isn’t a layer of paint, it won’t peel — and it never needs repainting or restaining to hold its look the way natural cedar does.
Authentic Wood Character
Each course is molded to reproduce the depth, grain, and shadow lines of hand-split shake, so the finished wall reads as genuine craftsmanship from the curb — the warmth of real wood, without the maintenance that comes with it.
The Toughest Storm Rating in Our Lineup
Portsmouth Shake is rated to withstand winds up to 200 mph — the highest wind rating of any siding we install. It won’t warp or buckle through heat or cold, which makes it a standout for storm-prone and coastal markets where exposure is part of daily life.
A Lifetime Limited Warranty
Portsmouth Shake carries a lifetime limited warranty, standing behind the product’s long-term performance for years of worry-free ownership.

Frequently Asked Questions
Portsmouth Shake is a UV-stabilized polymer siding engineered to reproduce the look of hand-split cedar shake. The polymer construction is what gives it its durability — it won’t rot, splinter, or absorb moisture the way natural wood does, and the UV stabilization helps it hold its color and character through years of sun exposure.
Both deliver authentic shake character without the maintenance of real cedar, so the right choice often comes down to the details. Portsmouth Shake is UV-stabilized polymer with a classic New England profile and the highest wind rating in our lineup at 200 mph, making it a strong fit for the most exposed coastal and storm-prone homes. Tando Beach Shake is a composite product with its own shake texture and the option of integrated Tando Stone accents. Your TIMEPROOFUSA consultant will help you compare the two on your actual home during your consultation.
No. The color is carried through the polymer rather than applied as a surface coat, so it won’t peel, and the siding never needs repainting or restaining — a sharp contrast to the ongoing upkeep natural cedar shake requires.
Very well. It is rated to withstand winds up to 200 mph and is engineered not to warp or buckle in temperature extremes. Combined with its moisture resistance, that makes it especially well suited to coastal exposure and storm-prone markets.
Portsmouth Shake performs beautifully across craftsman, colonial, cape, and cottage styles, in both coastal and traditional markets. Its profile makes it a natural fit anywhere that classic shake character belongs.

Our Reviews
The team that did the install was very professional. And the area was always clean and neat throughout the install process. It was the easiest install I have had!
We had damage from a fire and this team had someone on-site the next day. They were professional and experienced. The job was completed in three days, much appreciated effort.
I highly recommend timeproof. Jordan Filderman took the time to educate us on the different products and services they offer. Jordan made the entire process smooth and stress free. He was extremely professional.
Tyler W came to my home today. He was so delightful to talk to and helpful with all of my questions. If he is anything like the rest of your team, you hire well.
I called with a question on my roof (they didn't install)and they send someone out right away. Jeff was great. Went on the roof and checked it out. Thanks Jeff!
