The PreservationistA journal for the
life of your home.
A longer view
of home.
The Preservationist explores how we care for the homes we already have: what’s worth keeping, what needs attention, and what deserves a closer look before we change it.
Protecting what matters. Preserving what lasts.
A home is a collection of materials, decisions, and years of care. Our editorial focus is home preservation, building science, and smarter ownership: understanding how a home works and making thoughtful choices about its future.
We’re interested in innovative materials, responsible renovations, and the science of extending a home’s useful life. That means asking how a product works, what evidence supports it, where its limits lie, and when repair or replacement is the better answer.
Our existing roof guides are part of that larger conversation. They remain in the article archive as we develop the publication’s broader preservation coverage.
Know who’s publishing.
The Preservationist is published and owned by PSP Coatings, a business offering roof preservation assessments and treatment. PSP has a commercial interest in those services. Our publication reflects that perspective, and readers should know it when weighing our coverage.
Editorial coverage of a material or renovation topic doesn’t mean PSP offers that service. Links to PSP services are identified as such. Any paid placement, sponsorship, or affiliate relationship belongs alongside the content it supports, clearly labeled.
PSP Nano Roof Protection is the name of PSP’s service. PSP doesn’t manufacture or invent the underlying treatment chemistry. Meet PSP and its founders. Read about the publisher’s byline.
Follow the evidence.
Our standard is to connect technical claims to relevant primary sources: product documentation, applicable research, manufacturer guidance, and official resources. We distinguish a manufacturer’s statement from independent findings, and an explanation or estimate from a measured result.
Evidence needs context. A result for one material or product doesn’t establish performance for another. For roofing, water beading alone doesn’t establish compatibility, remaining roof life, or warranty coverage. Our product evidence and compatibility reference explains the documentation behind our roof treatment coverage.
These articles help readers prepare questions and compare decisions. They don’t assess a property remotely or replace an appropriate professional’s evaluation of the actual building.
Make attribution and dates meaningful.
Bylines identify the contributor or publishing organization responsible for an article. PSP Coatings is the organizational byline when no individual contributor is named. It doesn’t imply an engineer, laboratory, or independent technical reviewer.
Publication and update dates appear when they’re recorded. Our original evergreen guides don’t have a documented public release date, so we don’t invent one. A new publication name doesn’t make an older article newly reported news.
Editorial images support the subject of a story. They aren’t independent evidence of product performance. Any reported PSP project or customer result must be identified and supported by its own source material. News, explanatory guides, comparisons, and opinion should be presented for what they are.
Keep the record useful.
Readers can request a correction or clarification directly by email. Include the article URL, the passage in question, and any supporting source so PSP can review the issue.
Our corrections policy is to explain substantive factual corrections on the affected article. Routine spelling or formatting fixes don’t change an article’s publication date. New information should be identified as an update, with the original publication history retained when it’s available.
