Roofs on Mars and Adams Township Homes
Mars Borough has an older, walkable core with smaller lots and homes from the early 1900s, where we see the usual older-home issues: layered shingles, board sheathing and chimneys that need new flashing. Most of the Mars (16046) mailing area, though, is Adams Township and its newer neighborhoods, where two-story colonials and larger homes built in the last 30 years dominate.
Those newer homes bring their own roof problems. Builders often used basic shingles that are now 20 to 30 years old, and the rooflines are complicated: multiple gables, steep front elevations, dormers, long valleys, and bonus rooms over garages that are hard to ventilate and prone to ice dams. Hilltop lots with open exposure take more wind than tree-sheltered city streets. A good replacement fixes the ventilation and valley details, not just the shingles.
Our Roof Replacement Work in Mars
Our invoice records show 55 roof replacement jobs for Mars addresses since December 2017, most of them between 2017 and 2020, with work continuing into 2025. That is more than any other community north of Pittsburgh on our books and more than most of the South Hills towns closer to our office.
- Complete tear-offs on 1990s and 2000s two-story homes whose original builder-grade shingles had worn out.
- Valley and dormer rebuilds on complex rooflines where most leaks start.
- Ventilation corrections: adding or balancing intake at the soffits and exhaust at the ridge, especially over bonus rooms and cathedral ceilings.
- Older Mars Borough homes with multiple layers and chimneys that needed new step and counter flashing.
We also have a Mars roofers page covering our general roofing services here, and you can see where we have worked on our completed projects map.
Permits and HOA Approval in Mars and Adams Township
Mars Borough and Adams Township are separate municipalities in Butler County, and each handles its own permits and code enforcement. Whether a like-for-like reroof needs a permit depends on the municipality and the scope (structural or decking changes can make a difference), so we confirm the current requirement for your address and handle what applies before the crew is scheduled.
Many Adams Township neighborhoods also have a homeowners association with architectural guidelines for roof color or material. If yours does, we can provide the product name, color and spec sheets for your HOA submission, and we schedule installation after approval. If you are unsure, check your HOA documents or ask your association manager before choosing a color.
How Much Does a Roof Replacement Cost in Mars, PA?
Based on our own invoices for full roof replacements completed from 2024 through 2026 (177 jobs), most projects have landed between about $9,000 and $29,000, with the middle half between roughly $12,500 and $23,500. These are typical ranges, not quotes: every roof is different and your price can fall outside them.
What moves the number: roof size and pitch, how many layers have to come off, decking that needs replacing, chimneys, skylights and valleys that need new flashing, ventilation upgrades, and the shingle line you choose (architectural shingles versus metal or low-slope sections). Insurance-covered storm claims follow the adjuster’s scope.

What Drives Cost on Mars-Area Homes
Newer homes here tend to be larger and more cut-up than a basic ranch, so square footage and complexity drive most of the price. Your proposal will address:
- Total roof area, often larger on two-story Adams Township homes
- Number of valleys, dormers, gables and roof-to-wall transitions
- Steep front elevations that need extra safety equipment
- Skylights and whether to replace or remove them
- Ventilation corrections over bonus rooms and cathedral ceilings
- Decking repairs, usually limited on newer homes and more common on older Mars Borough houses
Roof financing is available if you would rather spread the cost out.
The Roof System We Install in Mars
On most Mars roofs we install the Owens Corning TruDefinition Duration architectural shingle as part of a complete Owens Corning system: starter strip, synthetic underlayment, ice and water barrier at the eaves, valleys and penetrations, matching hip and ridge caps, and ridge or other exhaust ventilation balanced with intake at the soffits. Duration shingles use SureNail technology, a reinforced nailing strip that holds fasteners well in wind, and TruDefinition colors are blended for depth, which is why they are the line we use most.
Peak Precision Contracting is an Owens Corning Platinum Preferred Contractor, and we offer optional warranties up to 25 years. Read more on our roof warranty page and in what Platinum Preferred means for you.
On complex Adams Township rooflines we pay particular attention to valleys (ice and water barrier the full length, clean cut or woven per the manufacturer’s instructions), step flashing at every sidewall, and new flashing kits for skylights. Our guide to skylights and leak prevention explains why skylights are a frequent leak point on homes of this age.
Repair or Replace Your Mars Roof?
If your Mars-area roof is 15 to 20 years old and the problem is a single leaking skylight, a lifted section after a wind storm, or a failed pipe boot, a repair is usually the smart move. We will tell you so and quote it.
When original builder-grade shingles are 20 years old or more, are losing granules into the gutters, curling or cracking on several slopes, or leaks keep showing up in different places (often in valleys or over a bonus room), replacement usually costs less over time than repeated repairs.

Emergency Leaks and Wind Damage in Mars
For an active leak, call (412) 498-4299. We offer emergency roof repair and tarping; because Mars is farther from our office than our South Hills jobs, we will give you an honest arrival time based on distance, weather and how many calls are waiting, then schedule the permanent repair.
Open hilltop subdivisions are prone to wind-lifted and missing shingles. After a storm, look for shingle pieces in the yard and dark patches on the roof, and avoid climbing up yourself. We document damage and can meet your adjuster; coverage is decided by your insurer. See storm damage and insurance claims and our warning about out-of-town storm chasers.

Mars Roof Replacement Questions

Do you really work in Mars and Adams Township from Canonsburg?
Yes. Mars is about 40 miles from our Canonsburg office, and our records show 55 roof replacement jobs for Mars addresses since 2017. We schedule estimates and installs in the area regularly.
Do I need a permit to replace my roof in Mars or Adams Township?
Mars Borough and Adams Township each handle their own permits. Whether a reroof needs one depends on the municipality and the scope of work, so we confirm the current requirement for your address before scheduling.
My HOA has to approve the shingle color. Can you help?
Yes. We provide the Owens Corning product name, color and spec sheets for your HOA application and schedule installation once it is approved.
Why does my bonus room get ice dams or feel hot?
Rooms over garages and cathedral ceilings often have little space for insulation and airflow, so heat escapes into the roof deck. During a replacement we check intake and exhaust ventilation and recommend corrections where needed.
Our 2000s home still has its original roof. Is it time?
Often, yes. Many original builder-grade shingles from that era are at or past their expected life. We inspect the roof and attic and tell you honestly whether you have years left or should plan a replacement.
How long does a roof replacement take on a two-story Mars home?
Most homes take one to two working days once materials arrive. Larger or very cut-up roofs, skylight replacements or ventilation changes can add time.
What warranties come with a new roof?
We offer optional warranties up to 25 years, and the exact term for your project is written into your contract.
Are you licensed and insured?
Yes. Peak Precision Contracting is licensed and insured, Pennsylvania HIC PA132469.
