Shed Roof Replacement Quote in Manassas, VA: Full Tear-Off on a 13×10 Outbuilding

Back to Recent Projects

When Ed in Manassas, VA reached out through Angi Leads, his ask was something a lot of full-service roofing companies turn down: he wanted a full tear-off and re-roof on his backyard shed. Not the house — the shed. A 13x10 outbuilding where the shingles had run their course and the decking underneath was due for replacement too.

Our Manassas roofing team said yes, walked the project, and put together a proposal. Here's a look at what's in the scope, why we're happy to take on smaller outbuilding projects, and what it costs to do a shed re-roof properly.

The Project: A Full Tear-Off on a 13×10 Backyard Shed

Ed's shed is a single-story 13x10 outbuilding with a shingle roof that's reached the end of its useful life. Rather than patching a roof that was already past its expected lifespan, Ed asked us to tear off everything — shingles, underlayment, and any rotted decking — and rebuild it from the deck up.

That's a sensible call. On a small outbuilding, the labor cost of patching is often close to what a full re-roof costs, but the patch leaves you with mismatched shingles and a roof that's still aging out. A full tear-off resets the clock and gives you a clean, watertight shed roof that should outlast most of what it's protecting inside.

Why a Real Roofing Company for a Shed Job?

A lot of homeowners assume professional roofers don't take small jobs. That's often true — many bigger companies have minimums that knock outbuilding work out of consideration. But our approach has always been that if it's a roof, we'll roof it. Whether it's a 30-square primary residence, a detached garage, or a 2-square shed, the principles are the same: tear off cleanly, address what's underneath, install proper underlayment and flashing, and finish with a quality shingle.

A shed is also a place where workmanship really shows. There's no soffit-and-fascia complexity, no chimney, no skylights — just deck, underlayment, drip edge, and shingles. If a contractor cuts corners on a shed, those corners are visible, and they cost the homeowner the same way they would on a house.

The Scope We Quoted: Tear-Off, Decking, Underlayment, and New Shingles

The proposal covers a complete shed re-roof:

  • Remove all existing shingles from the shed roof
  • Address any rotted decking discovered during tear-off
  • Install new underlayment across the deck
  • Install new aluminum drip edge along the eaves and rakes
  • Install new TAMKO Heritage architectural shingles
  • Hip and ridge cap matched to the shingle color (~25 LF)
  • Cenguard ice & water shield protection
  • Cenguard ridge vent for proper ventilation
  • Full cleanup and haul-away

Like all of our roofing proposals, this one includes a structural repair clause for any rotten OSB or plank board we uncover during tear-off. Decking issues on a shed aren't unusual — water finds its way in around vent penetrations, edges, and aging shingles, and over years that moisture can soften the wood underneath. Per the proposal, OSB replacement runs $100 per sheet and plank board runs $8 per linear foot if anything turns up beyond what's expected.

Why TAMKO Heritage Architectural Shingles for an Outbuilding

For this shed, we proposed TAMKO Heritage architectural shingles. Heritage is a solid value-tier architectural shingle — a step up from a basic 3-tab — that gives the shed a textured, dimensional look without paying for a 50-year premium product on what's ultimately a small outbuilding.

It's the right tier of product for the application. A premium 50-year architectural shingle isn't a bad choice for a shed, but it's overkill — Heritage gives you the wind rating, the layered look, and the longevity profile that makes sense on a structure that probably won't outlast the shingles themselves anyway.
