Roofing Contractor for Southeast Michigan

A Roof Is an Assembly, Not a Product

Roofing is one of the easiest trades to sell on price, because the visible deliverable looks the same regardless of what is underneath it. Two roofs with identical shingles can have very different service lives depending on the decking they are fastened to, the underlayment, the ice barrier at the eaves, the flashing at every penetration and wall intersection, and whether the attic beneath is properly ventilated.

In Michigan the eave detail matters more than in most climates. Freeze and thaw cycling drives ice damming, and the water that backs up under shingles does not care how good the shingles are.

Praxis Building Group approaches a roof as the whole assembly, which is also why roofing sits naturally alongside the rest of the work rather than as a separate transaction.

Typical Project Scope

A typical roofing scope includes:

• Evaluation of the existing roof, decking condition and attic ventilation
• Property protection: landscaping, siding, windows and driveway
• Complete tear off of existing roofing down to the deck
• Decking inspection and replacement of deteriorated sheathing
• Ice and water barrier at eaves, valleys and penetrations per code and exposure
• Synthetic underlayment across the field
• Drip edge, starter course and rake detail
• Valley treatment appropriate to the roof geometry
• Step and counter flashing at walls and chimneys
• Pipe boots, vent flashing and any penetration detail
• Shingle installation to manufacturer specification for warranty validity
• Ridge venting and intake ventilation correction where needed
• Ridge cap, cleanup and magnetic sweep of the site

Not every project includes every item. Scope is written for your specific house and stated plainly before pricing.

The Praxis Building Group Approach

Tear off rather than layover

Roofing over an existing layer is faster and cheaper in the moment. It also hides the decking, prevents proper ice barrier installation, adds weight and usually shortens the life of the new roof. We tear off. Where a homeowner specifically wants a layover, the tradeoffs get stated plainly first.

Ventilation gets corrected, not repeated

A large share of premature roof failure in Michigan traces to attic ventilation: too little intake at the soffit, exhaust and intake fighting each other, or bath fans discharging into the attic. Replacing a roof without correcting that repeats the failure on a new schedule.

Flashing is fabricated, not caulked

Every wall intersection, chimney, skylight and penetration is a flashing detail. Sealant is a supplement to correct flashing, never a substitute for it. Where existing flashing was installed with caulk as the primary defense, we rebuild the detail.

Roofing inside a larger project

When roofing is part of an addition, a whole home renovation or new construction, it gets sequenced with the framing and exterior work rather than scheduled as a separate visit. That is one of the practical advantages of having one company carry it.

Construction Considerations

Ice damming at the eaves

Ice dams form when heat escaping into the attic melts snow that refreezes at the cold eave. The result is water backing up under the shingles. The roof assembly addresses the symptom with ice barrier membrane. The actual cause is usually attic air sealing and insulation, which is a different scope worth considering at the same time.

Decking condition is unknown until tear off

The condition of the sheathing under a roof cannot be fully determined from the outside or, in many cases, from inside the attic. Some decking replacement should be expected as a line item, priced per sheet, rather than treated as a surprise.

Chimneys and skylights

These are the two most common leak sources on an otherwise sound roof. A roof replacement is the right time to rebuild chimney flashing properly and to decide whether an aging skylight should be replaced while the roof is open, because doing it later means disturbing new roofing.

Multiple planes and low slope sections

Complex roofs with several intersecting planes have more valleys and more flashing, which is where cost and risk concentrate. Low slope sections, common over porches and additions, may require a different roofing material entirely rather than shingles.

Planning This Project

Roof replacement is one of the few construction projects where timing is sometimes forced by an active leak. Where it is not, planning it alongside other exterior work, such as siding, gutters or an addition, avoids paying twice for staging and lets the details at the intersection of those systems be handled together.

Manufacturer warranties on shingles generally depend on installation to specification, including fastener count and placement, starter and ridge products, and in some cases ventilation. A price that is well below the others usually reflects a departure from that specification somewhere.
