Roofing in Troy, MI
Troy covers a lot of ground and several housing eras, from 1960s subdivisions through to much larger and more recent builds, sometimes within a few streets of each other. On the bigger Troy houses the cost of a roof sits in the detail work rather than the field, and that is the part quotes differ on.
3G Home Exteriors is family-owned and has worked out of Fraser since 2011. Troy is in Oakland County, inside the area our crews cover every week.

Why two quotes for the same Troy house differ by thousands
On a large roof the square footage is the easy part to price. The differences between quotes almost always sit in four places, and most of them are invisible from the driveway.
- Flashing policy — whether chimney, sidewall and step flashing is being replaced or reused. Reusing it is cheaper today and is where the leak comes back.
- Valleys — open metal, closed cut or woven, and whether new valley metal is in the price at all
- Ice barrier coverage — one course at the eave versus carried far enough inside the heated wall line to actually work
- Ventilation — whether intake is being corrected or only exhaust is being added, which is the cheap version that makes the attic worse
Ask any contractor to write those four into the scope. The quote that will not put them in writing is the one to be careful with.
Repair or replace in Troy
Not every call is a replacement. A roof with ten good years left and one bad valley is a repair, and we will say so even though the smaller job is worth less to us. What pushes a Troy roof into replacement is usually age combined with evidence: granules in the gutters, shingles cupping across a whole slope, or a deck that moves underfoot.
If the problem is a specific leak rather than general wear, our roof repair page covers how we trace it back to the source instead of patching where the water shows up inside.
Mature trees and what they drop
Large mature trees across much of the city mean branch impact and heavy debris load are as common a cause of damage here as wind itself. Debris sitting in a valley holds water against the shingle, and a valley that stays damp fails years before the rest of the roof.
After wind, hail or an ice event we inspect and photograph everything, then give you an itemised scope you can hand to an adjuster. What the carrier decides is between you and them. What we control is that the documentation is thorough, and there is more on our storm damage page.
The roof is part of the water path
Where water goes after it leaves the shingles decides whether the wall, the fascia and the foundation stay dry. We quote the whole path rather than the roof in isolation.

- Seamless gutters — sized from the actual roof area, not a standard size
- Leaf protection — matched to the roof pitch and the trees around it
- Exterior drainage — where the downspout puts the water
Roofing questions from Troy homeowners
On most Troy homes yes. It lies flatter, handles wind better and looks appropriate on a larger roof. Three-tab tends to look thin on a house of this size and it does not last as long.Is architectural shingle worth the upgrade?
Chimney and sidewall flashing, by a wide margin. Shingles get replaced and old flashing gets reused, and the leak comes back within a couple of seasons looking like a new problem.What is the most common leak point you find?
On a full replacement, yes. Reusing old step flashing to save money is a false economy and we will not quote it that way. It is written into the scope so you can compare it against other quotes.Do you replace flashing as standard?
Enough to carry past the inside face of the exterior wall, which on a shallow pitch with a deep overhang means more than a single course. One course at the eave is the cheapest compliant answer rather than the one that keeps water out.How much ice barrier should be on a Troy roof?
