After buying a two-family condo in Medford, the owners knew the aging, previously patched roof needed a closer look. Our detailed inspection gave them a clear picture of the shingle and low-slope roof conditions so they could make an informed long-term decision.
The owner had recently purchased the two-family property and already knew the roof was at least around 20 years old. The home inspection had raised concerns, and visible patchwork across the asphalt shingles made it clear that the roof had a repair history.
He was gathering multiple quotes and wanted to understand whether the condo should keep repairing individual areas or plan for replacement.
After a previous contractor spent only a few minutes at the property before sending a report, the owner specifically wanted a more thorough assessment that the owners could actually use to make a decision.
The roof was not failing because of one single defect. The inspection found an older three-tab shingle system with two existing layers, widespread weathering, missing shingles, and multiple repaired sections. Those conditions showed a pattern of accumulated repairs rather than one localized problem.
With aging visible across the field of the roof, continuing to chase individual missing or damaged shingles would not reset the condition of the underlying roof system. That is why full replacement was recommended over another round of spot repairs.
The low-slope roof sections also showed visible aging, prior patching, and sealant repairs along several transitions.
These areas require a roofing system designed specifically for low-slope conditions, so simply extending the shingle replacement over them would not be the right approach.
The final project therefore paired the new architectural shingle roof with a fully adhered 0.060 EPDM membrane system over 1-inch ISO insulation on the designated low-slope areas.
This allowed each roof section to be rebuilt with a system suited to its pitch and drainage conditions.

Several roof penetrations had been heavily covered with roof cement or sealant.
The chimney crowns also showed visible cracking, while previous flashing work was evident around the masonry.
These details may hold temporarily, but they become less dependable as sealants age and crack.
A full reroof created the opportunity to rebuild those transitions correctly instead of installing a new roof around old patchwork.
The contracted scope included new step flashing at roof-to-wall transitions, new chimney flashing and counterflashing where required, and properly integrated penetration details.
Once the owners had the full condition report, the decision was no longer based on the roof’s age alone.
They could see the combination of two shingle layers, widespread repairs, aging low-slope roofing, and vulnerable transitions across the system.
The signed scope called for complete tear-off to the roof deck, deck inspection, ice and water protection at critical areas, synthetic underlayment, new aluminum drip edge, GAF Timberline HDZ architectural shingles, new ridge ventilation, and a fully adhered EPDM assembly on the designated low-slope section.
The homeowner first question was straightforward: what does this roof actually need? The inspection gave the condo owners a documented answer they could compare against other quotes instead of relying on a quick visual opinion.
Rather than continuing a cycle of isolated repairs, the project moved forward as a coordinated shingle and EPDM replacement designed to address the roof as a complete system - including the transitions, flashing, ventilation, and low-slope areas that had accumulated repairs over time.

A stronger outcome for this homeowner was not simply “new shingles.”
It was eliminating the same recurring weak points that had required repeated attention.
Replaces an aging two-layer shingle system with widespread prior repairs instead of continuing isolated fixes.
Pairs architectural shingles on pitched areas with fully adhered EPDM on designated low-slope sections.
Integrates new flashing, penetration details, and edge protection into the replacement roof system.
Adds low-profile ridge ventilation as part of the new shingle roofing assembly.
The value of the inspection was not simply being told that an older roof should be replaced.
It was seeing why replacement made sense: two existing shingle layers, widespread repairs, aging low-slope sections, and roof details that had repeatedly relied on sealant and patching.
That documentation gave the condo owners a clearer basis for comparing proposals and planning the work.
The resulting scope replaced both the pitched and designated low-slope roofing systems while addressing the flashing and ventilation details that needed to work with the new roof long term.
A roof inspection should help you understand what you are looking at before you commit to a major project.
Peak Quality Roofing provides a detailed Roof Health Report and clear recommendations so you can compare options and decide what makes sense for your property.
Age is only one factor. The decision should also consider how widespread the wear is, the number of prior repairs, the condition of flashing and penetrations, the number of existing roof layers, and whether localized repairs can reasonably restore reliable performance.
Yes. An inspection can be especially useful before a leak develops because it allows owners to identify aging materials and vulnerable details while there is still time to compare options and plan the work.
Low-slope sections need a roofing system suited to limited pitch and slower drainage. In this project, the designated low-slope area was specified with a fully adhered 0.060 EPDM membrane over insulation, while architectural shingles were used on the pitched roof areas.
When full replacement is performed, the existing roofing is removed so the roof deck can be inspected before the new system is installed. Multiple existing layers can also be an important factor when deciding whether continued patching makes sense.
Yes. Peak Quality Roofing provides roof inspections, roof repairs, and full roof replacement services in Medford and surrounding Greater Boston communities, including properties with both shingle and low-slope roofing systems.
