Our Services

At William Penn Roofing, we build trust with our customers by putting their needs first. Below is a detailed list of the services we offer in Princeton, including roof inspections, full roof system replacements, and partial roof replacements.

Over time, your roof endures a lot of wear and tear from the elements, resulting in age- and weather-related damage that requires your roof to be replaced. William Penn Roofing’s technicians are certified specialists in installing the highest-quality roofing materials available. 

Along with a 50-year warranty on full shingle roof replacements from the top 3 manufacturers, we provide our customers with efficient, high-quality services to ensure your home or business is protected from the elements for years to come. A roofing company should always stand behind the work they provide, for this reason we also offer our customers a 10 year workmanship warranty. As an added bonus, all warranties are transferrable to one additional homeowner If you are planning to sell your home in the future. This can be a great selling feature when listing your home on the market.

The best time to have a roofing inspection is during milder temperatures like in spring, autumn, or after a severe weather event like hail, high winds, heavy rains, or tornadoes. Extreme cold or extreme heat can cause wear and tear on your roof, when walked on, which can lead to an unsightly appearance, or create a gateway for greater damage over time. Our professional roofing inspections help catch and alleviate problems early, saving you time and stress in the long run. 

Not all roofing damage requires a total roof replacement. Some may require minor repairs, while others may require more complex work like a full facet replacement. Partial replacements are a sensible, cost-effective option for those who have trouble with leaks or other issues in a specific area of their roof. 

William Penn Roofing’s technicians are experienced in handling a variety of roofing materials, including: 

  • Slate
  • Cedar
  • Metal roofing
  • Asphalt shingles
  • Protective roof coatings
  • Flat roofing systems

William Penn Roofing is ready and able to care for your roofing needs, no matter how large or small the project. Whether you need a complete roofing replacement or a simple visual inspection, call us today.

Slate roofs are some of the heaviest and most expensive on the market compared to other roof types. Despite the price, slate is a great roof option. Slate roofs can last from 60 to 150 years depending on the slate tiles used and weather conditions.

Slate is resistant to damage from mildew, mold, fire, pests and water.

It’s hard to replicate the character and beauty of slate. It may increase the resale value of your home and attract buyers with its timeless appearance.


Cedar shingle roofs add a rustic beauty to any home and mature attractively over time. They cost more due to the use of higher-end roofing materials used, but cedar shake roofs last around 30 years.

Cedar is strong and durable, resistant to bugs, and can provide better air circulation within your home. It is recommended that maintenance is performed every 2 to 4 years to guarantee the longest life possible.

Copper roofs are a special and signature type of roof with an upscale, classy feel. The gleam of a copper roof is unmistakable. Copper roofs typically last anywhere from 70 to 80 years and can typically last longer in ideal conditions.

Copper is highly resistant to fire, hail, and mildew. As lightweight roofing material, copper does not put as much stress on your home’s internal structures as heavier materials. This is especially important during heavy snowfalls.

Installing a copper roof can help you control heating and cooling costs.

Mod-bit roof stands for modified-bitumen roofing, which is a hybrid system derived from traditional built-up roofing methods combined with modern roofing technology

This type of roof is durable, weather resistant and a type of low-slope roof. Mod-bit roofs typically last 20 years, but can last longer if they are properly maintained.

Modified Bitumen Roofing Systems are designed with a 5 layer composition to withstand harsh exposure to all seasons and other dangerous environmental elements.

TPO or better known as thermoplastic polyolefin roof is a single ply membrane with reinforcing and polymer fillers used on a flat roof. These roofing systems are environmentally friendly! They also resist chemical and ultraviolet exposure. A TPO roof can last anywhere between 15 to 30 years.

TPO roofing contains a blend of rubbers and other elements that add to its durability and flexibility.

Also, TPO roofs can stand up to ultraviolet damage and chemical exposure, extending its lifespan. This quality can also help dramatically lower your HVAC costs in hot weather.


Need More Than Just Roofing? Here’s How We Can Help

Roofing may be in the name, but we provide Princeton residents with a host of other great exterior services.

Sagging Gutter

Gutter Services

Clean, well-kept gutters are essential to protecting your home from water damage. They guide rainwater and melting snow away from the siding and foundation, preventing it from pooling and causing erosion and mold growth. William Penn Roofing provides a range of gutter maintenance services, including:

- Full gutter installations
- Gutter protection installations
- Cleaning services

These services ensure every component of your roofing system is operating at peak efficiency.


Siding Services

When it comes to your home’s curb appeal and longevity, durable siding is just as important as a well-maintained roof. We offer complete and partial siding replacements for home and commercial buildings, with an array of siding style options to meet your aesthetic and architectural needs. If your siding is weathered, faded, or damaged, our knowledgeable technicians can replace it with materials from the Nation’s leading siding manufacturers. When you trust William Penn Roofing with your siding installation services, you get professional results every time.

They offer a way to boost ambient light in your space, provide visual spaciousness, fresh air, and can increase the resale value of your space if you ever decide to sell it.
