Commercial Roofing Contractors in Western Pennsylvania
Lester’s Roofing & Carpentry is a commercial, industrial and agricultural roofing contractor based in Rossiter, in northern Indiana County. We have been working on roofs across western and central Pennsylvania for over 16 years.
We are a certified Conklin Roofing Systems contractor and a registered Pennsylvania Home Improvement Contractor, HIC #PA042939. Most of what we do is roof restoration and coatings, metal roof repair, leak tracing and repair, and replacement on commercial, industrial and farm buildings. We handle residential roofing as well.
Call 814-952-2469 for a free roof inspection anywhere in our service area.
Where We Work
Rossiter sits in the middle of our service area rather than at the edge of it, which is worth knowing if you are trying to work out whether we cover you.
The four counties we are in most are Indiana, Cambria, Clearfield and Somerset. Those are close to home and we work in them constantly. Beyond that we regularly take jobs in Jefferson, Armstrong, Blair, Centre and Westmoreland Counties, and we go as far west as Pittsburgh for commercial work.
Being straight about the edges of that. A roof in Rossiter or Nanty Glo we can get to quickly. A commercial roof in Export or Pittsburgh is a longer run, so we plan work in those areas together rather than making single trips out and back. For a commercial or agricultural roof that is rarely a problem, because the work gets scheduled in advance anyway. If you need something looked at, call and we will tell you honestly when we can be there rather than promising a day we cannot make.
If your town is not in the list below, it is still worth asking. That list is where we have built pages, not the boundary of where we go.

What We Do
- Roof restoration and coatings. Renewing a sound roof in place instead of tearing it off, where the deck and insulation allow it. This is the bulk of our commercial work.
- Metal roof repair and coating. Fasteners, seams, ridge and flashing work on barns, workshops and industrial buildings.
- Roof leak repair. Finding where water is actually entering, which is rarely directly above where it appears inside.
- Flat and low-slope roofing. EPDM, TPO, modified bitumen and the penetration details around them.
- Roof maintenance programs. Scheduled inspections, drainage clearing and minor repairs, with the written records a warranty needs.
- Roof replacement. For when restoration is not the right answer.
- Residential roofing. Repairs, shingle work and metal roof installation on homes.
There is a full list on our commercial roof services and commercial roof types pages.
Buildings We Work On
Western Pennsylvania has a particular building mix, and most of our work sits in the commercial, industrial and agricultural end of it.
- Commercial buildings: offices, retail units, churches, medical and professional buildings
- Warehouses and distribution buildings
- Industrial and manufacturing facilities
- Farm buildings: barns, machine sheds, pole barns and workshops
- Aircraft hangars
- Homes
If you own a large low-slope or metal roof, that is squarely what we do. More on the industry roofing page.
Why Use a Contractor Based Two Counties Away
It is a fair question, and it deserves a straight answer rather than a sales one.
For a straightforward residential repair, the nearest good roofer is usually the right call, and we will say so. The reason people bring us further afield is that commercial roof restoration is a narrower trade than roofing generally, and the relevant comparison is not the nearest roofer but the nearest roofer who does this particular work.
Certification is not universal. A Conklin restoration system has to be installed by a certified contractor for the manufacturer warranty to stand. That is not a marketing point, it is a condition of the warranty, and it means the pool of contractors who can actually deliver it is smaller than the pool of roofers in your county.
Coating a roof is a different skill from replacing one. Knowing when a roof can be restored, and being willing to tell you when it cannot, takes having done a lot of them. A contractor who only replaces roofs will tend to recommend replacing your roof.
Agricultural and industrial metal is its own thing. Large exposed-fastener metal roofs fail in specific, predictable ways, and the repairs are not the same as residential work.
Whoever you end up using, including us, these are the questions worth asking before you sign anything:
- Are you certified by the manufacturer of the system you are proposing, and can you show me?
- Is this roof a candidate for restoration, and if not, why not?
- What exactly does the warranty cover, who stands behind it, and what would void it?
- Is there a separate workmanship warranty on your labor?
- Can I see a building like mine that you have done?
If a contractor is uncomfortable with any of those, that is useful information.
Roof Warranties
Where a Conklin restoration system is suitable, it carries a 20-year non-prorated manufacturer warranty, with the option to renew for a further 20 years, subject to the system installed and its renewal requirements. Lester’s Roofing & Carpentry also provides its own 3-year contractor workmanship warranty.
Warranties like that depend on the roof being inspected and maintained, so the maintenance records matter as much as the paperwork you get at installation. There is more detail on our roof warranty page.
Free Roof Inspections
We provide free roof inspections on commercial, industrial, agricultural and residential buildings throughout our service area.
An inspection tells you what condition the roof is genuinely in, where water is getting in if it is leaking, and whether the roof can be repaired or coated rather than replaced. You get a written report with photographs and a price based on what we found.
Most building owners find out about their roof when it starts leaking. An inspection is how you find out before that, and it is what turns a roof from an emergency into a budget line.

Service Area FAQs
My town is not on your list. Do you still cover it?
Probably. The list above is where we have built pages, which is not the same as the boundary of where we work. If you are in or near Indiana, Cambria, Clearfield, Somerset, Jefferson, Armstrong, Blair, Centre or Westmoreland County, call and ask. The worst outcome is that we tell you we are not the right people and point you somewhere better.
How far do you actually travel?
It depends on the job more than the miles. A large commercial or agricultural roof justifies a longer trip than a small repair does, so we will travel further for a restoration on a warehouse or a barn than we would for a single flashing repair. The honest version is that we would rather tell you on the phone than have you wait for a visit that does not make sense for either of us.
Do you charge for the inspection or for travel?
The roof inspection is free, and you get a written report with photographs whether or not you go ahead with any work. There is no charge for coming out to look.
Do you only do commercial work?
No. Commercial, industrial and agricultural roofing is the bulk of what we do and it is our specialism, but we do residential roofing too, including repairs, shingle work and metal roof installation on homes.
Are you licensed and insured in Pennsylvania?
Yes. We are a registered Pennsylvania Home Improvement Contractor, HIC #PA042939, and we are a certified Conklin Roofing Systems contractor. You can find more about the company on our about page.
Is there any funding help available for a roof in Pennsylvania?
There can be, depending on the building, the owner and the program. We have put together what we know on our roofing grants in Pennsylvania page.
