Single Family Roof Replacement on Dorset Ct in Allentown, PA | Roofera
A Real Roofera Project in Allentown, PA
This single family roof replacement in Allentown, PA on Dorset Ct came to Roofera through a referral — and once we got on the roof, it was clear why the homeowner hadn’t waited any longer. The existing shingles were so far gone that walking on them sent granules cascading off in every direction. Dust and debris had been working their way into the garage for months, a telltale sign that the shingles had lost their protective layer and the roof was well past its useful life.
At 33 squares, this was a substantial roof. The homeowner had been living with the slow deterioration and finally made the call. With temperatures hitting 95 degrees on the day of installation, the crew managed the heat carefully — pacing the work and handling the shingles with the adjusted technique that high temperatures require.

Did you know?
South Allentown is home to a wide range of single-family residential properties, many of which were built in the mid-to-late 20th century and are now reaching the age where original or early replacement roofs need attention. Granule loss and shingle aging are among the most common issues we encounter on homes in this part of the Lehigh Valley — often the homeowner has been watching the decline for a year or two before making the call.
A single family roof replacement in Allentown, PA on a 33-square home is a significant project that requires proper planning, the right crew size, and materials staged correctly for a full-day installation. Summer heat in Allentown regularly pushes into the 90s, which means scheduling and technique matter as much as the materials themselves.
Referral-driven projects like this one are a reflection of the work we do in every South Allentown neighborhood — homeowners who’ve seen Roofera’s work firsthand recommending us to people they care about.
What We Found During the Inspection
This single family roof replacement in Allentown, PA started with an inspection that confirmed what the homeowner already suspected — the roof had run its course and there was no patching left to do.
Once we got on the roof, we found:
- Shingles so heavily granule-depleted that walking on them dislodged material with every step
- Widespread granule loss across all 33 squares — the protective surface layer that shields asphalt shingles from UV and weather was essentially gone
- Dust and granule debris accumulating in the garage below — a clear sign the roof had been shedding material for months
- No ridge ventilation — the attic had no meaningful airflow, which accelerates shingle wear from below by trapping heat
- Shingles brittle and breaking apart, well beyond the point where repairs would hold
The good news: the decking underneath was solid. No replacement needed — just a clean tear-off and a fresh installation on a structurally sound base.
How We Solved It
For this single family roof replacement in Allentown, PA, we performed a complete tear-off of all existing shingles and started fresh on the solid decking beneath. Working in 95-degree heat required discipline — the crew scheduled the most demanding work for the cooler morning hours and managed shingle handling carefully to ensure a proper bond and clean installation throughout the day.
Work completed on this project:
- Complete tear-off of the existing shingle system across all 33 squares
- FeltBuster premium synthetic underlayment installed across the entire roof surface
- WeatherWatch ice & water shield applied at all eaves and vulnerable penetrations
- GAF Timberline HDZ Hickory shingles installed across the full 33-square roof
- Ridge cap shingles applied along all ridgelines
- New continuous ridge vent installed at the peak for proper attic ventilation
- Job site fully cleaned and cleared before end of day
The ridge vent was an important addition on this job. Without proper attic ventilation, heat and moisture build up underneath the roof deck — one of the key reasons the previous shingles wore out as fast as they did. The new vent ensures the replacement system has the airflow it needs to perform over the long term.

Materials Used on This Project
GAF Timberline HDZ – Hickory
A warm, dimensional architectural shingle with a natural wood tone. Hickory complements the brick and neutral siding common on South Allentown single-family homes.
FeltBuster Premium Synthetic Underlayment
Installed across all 33 squares as a secondary moisture barrier beneath the new shingles.
WeatherWatch Ice & Water Shield
Applied at all eaves and penetrations for added leak protection at the most vulnerable areas of the roof.
New Continuous Ridge Vent
Installed along the roof peak to provide consistent attic ventilation — an important upgrade on a home that had been running without proper airflow.

Questions About This Type of Project
How do I know when granule loss means it's time to replace my roof?
When granules are coming off in significant quantities — collecting in gutters, on the ground, or tracking into your garage — it means the protective surface layer of your shingles is gone. At that point the asphalt underneath is exposed to direct UV and weather, and the shingles will deteriorate rapidly. If you’re seeing that level of granule loss across the full roof, replacement is almost always more cost-effective than continued patching.
What is a roofing square and how big is a 33-square roof?
One roofing square equals 100 square feet of roof surface. A 33-square roof covers approximately 3,300 square feet of roofing area — a substantial single-family home that requires proper crew sizing, material staging, and scheduling to complete in a single day.
Can a full roof replacement really be done in one day on a 33-square home?
Yes — with the right crew, proper material staging, and good weather conditions. This Dorset Ct project was completed in a single day despite 95-degree temperatures, which required careful pacing and scheduling to maintain both crew performance and installation quality throughout the day.
Why is ridge vent important on a home that didn't have one before?
Without a ridge vent, heat and moisture have nowhere to escape from the attic. That trapped heat accelerates shingle aging from below — one of the factors that contributed to the rapid wear on this Dorset Ct roof. Installing a continuous ridge vent gives the new shingles the ventilation they need to reach their full lifespan.
