Commercial Roof Replacement in Stratham, NH for Multifamily Townhome Complex

What made this Stratham roofing project different from a typical residential job?

Most roofing projects involve a single home, a single owner, and one set of rooflines to manage. This project in Stratham, NH was a different animal entirely: a commercial multifamily townhome complex where the roofing system spans multiple units, multiple roof planes, and ultimately protects multiple families living in shared structures.

That complexity changes how a roof replacement must be approached. There is no room for inconsistency when an entire complex is involved. Every unit needs the same quality of installation, the same materials, and the same attention to detail at every flashing transition and penetration point. A section that is installed differently from the rest of the complex becomes the weak link in a system that property owners will be managing for years.

The existing asphalt roofing system had reached the end of its useful life across the complex and needed full replacement. Compass Exteriors was brought in to handle the project from start to finish — full tear-off, system upgrade, and consistent installation across every section of the property.

What roofing system was installed across the townhome complex?

The replacement system was built around Owens Corning TruDefinition® Duration® shingles in Slatestone. Slatestone is a clean, cool-toned gray that reads professionally across multiple connected rooflines and complements the kind of architectural uniformity that multifamily properties require. Color consistency matters on a complex like this — mismatched or fading sections across units affect both curb appeal and property value.

Beyond the shingles, the full system was upgraded with components that address the specific vulnerabilities of New England multifamily roofing:

• High-quality drip edge — proper water management at the eaves to prevent fascia deterioration and ice dam damage at the roofline
• Ultimate pipe boots — long-term leak protection at every penetration, a common failure point on older multifamily properties
• Titanium ice and water shield — protecting vulnerable areas at eaves, valleys, and penetrations against the freeze-thaw cycles that Stratham sees through a New Hampshire winter

A shingle-only replacement without upgraded components leaves the complex exposed at the exact points where failures tend to originate. On this project, every element of the system was addressed.

Why does uniform installation quality matter so much on a multifamily property?

On a single-family home, an inconsistent installation might create a problem in one section that eventually gets addressed. On a multifamily townhome complex, inconsistency across units multiplies that risk. Residents in poorly installed sections experience leaks and interior damage while residents in better-installed sections do not. That leads to ongoing service calls, repair costs, and legitimate complaints from residents who are experiencing problems their neighbors are not.

The goal on a project like this is a uniform, high-performance system that protects every unit equally. That means the same care at every valley, the same flashing standards at every penetration, and the same inspection rigor across every section of the complex before the crew leaves the property.

How does New Hampshire winter weather affect a multifamily roofing system?

Stratham sees the full range of New England winter conditions: snow accumulation, ice dam formation at eaves, wind-driven moisture, and repeated freeze-thaw cycles that stress every joint and transition in a roofing system. Multifamily properties are particularly exposed because the rooflines are typically lower-pitched and cover larger continuous areas than a single-family home, creating more surface area for ice dam development.

That is exactly why the Titanium ice and water shield on this project was not a luxury — it was a system requirement. Properly protected eave zones and valley areas are the difference between a complex that needs emergency calls every winter and one that manages seasonal stress the way it was designed to.

What should property owners and managers know before a commercial reroof?

For owners and managers considering a reroof on a multifamily or commercial property in Stratham, a few things are worth knowing before you start soliciting bids:

• Treat it as a system, not just a shingle replacement — the accessories matter as much as the shingle on a property of this type
• Require a full tear-off in your scope — a recover hides deck conditions and adds weight without correcting underlying problems
• Inspect for consistent installation across all units — ask what the quality control process looks like during and after installation
• Confirm warranty coverage details — product warranty terms and workmanship warranty coverage are worth reviewing carefully on a commercial-scale investment

Compass Exteriors approaches commercial multifamily roofing projects with the same thoroughness we bring to every residential job — honest inspection findings, clear scope of work, and installation quality that holds up through New England weather.
