What Is a Built-Up Roof on a Hudson Building?
A built-up roof on a Hudson building is the traditional tar and gravel flat roof, made of layers of asphalt and roofing felt with gravel on top. It typically lasts about 30 years, longer than EPDM, TPO or modified bitumen usually do.
As a built-up roof ages, the asphalt dries and cracks with age and freezing, gravel washes away from low spots and leaves the layers bare, and flashing at walls and edges pulls loose. Western Wisconsin's roughly 45 to 50 inches of snow a year, and the meltwater that sits on a flat roof, find every one of those openings.
How long it lasts
About 30 years
Weather, material quality and upkeep decide whether a built-up roof reaches that age.
What Are the Signs Your Hudson Built-Up Roof Needs Work?
The signs a Hudson built-up roof needs work are leaks or stains below, bare patches where the gravel has gone, cracks and blisters in the surface, standing water, and flashing pulling away at the walls and edges.
Leaks and Stains
Water stains or drips inside mean water is already through the layers.
Bare Spots
Patches where the gravel has washed away leave the asphalt open to sun and weather.
Cracks and Blisters
Cracked or bubbled asphalt shows layers drying out or trapping moisture.
Loose Flashing
Flashing pulling away at walls, edges and vents is a common leak point.

Should You Repair or Replace Your Hudson Built-Up Roof?
You should repair a Hudson built-up roof when the leak comes from one area or one flashing and the layers elsewhere are sound, and replace it when the roof is cracked, bare and leaking across much of its surface. A sound roof that is starting to dry out can also be sealed with roof coatings.
Repair it when
- The leak traces to one area or one flashing
- The layers are intact elsewhere
- The insulation and deck are dry
- The roof is well short of 30 years
Replace it when
- Leaks are turning up in several places
- Cracks and bare spots cover much of the roof
- Insulation or decking is soaked or soft
- The roof already carries two layers of roofing
When a built-up roof is replaced, the new roof can be a modified bitumen roof, another asphalt-based system laid in plies, or to a single-ply membrane. We go through the options and prices with you as part of flat roof replacement.
Not sure if your built-up roof can still be repaired?
We will check the layers and what is under them, and tell you which way makes sense.
What Does a Built-Up Roof Cost in Hudson?
A built-up roof costs $4 to $10 per square foot installed as a national range, not a quote, and a flat roof repair of any type runs $300 to $1,100. No published figure exists for Hudson itself, and the price for your roof depends on its size, how much comes off and the state of the deck.

What Rules Apply to a Built-Up Roof in Hudson?
The rules for a built-up roof in Hudson depend on whether it covers a home or a business. On a one- or two-family home, Wisconsin's dwelling code requires a new roof to go on to the manufacturer's instructions or a recognized national standard, and forbids a new roof over one that already has two or more layers or is water-soaked or deteriorated, so an old built-up roof in that state is torn off.
In the City of Hudson, new or replacement roofing on a home needs no building permit when there are no structural changes or repairs, while structural work does. Commercial buildings are not covered by the state's one- and two-family dwelling code, so for a business, and for homes outside the city, we confirm the permit rules with the local building inspector before work starts.
Who Can Work on a Built-Up Roof on a Hudson Home?
A contractor holding Wisconsin's Dwelling Contractor certification, with a certified Dwelling Contractor Qualifier, can work on a Built-Up Roof on a Hudson Home, because that is the credential the state requires of anyone who pulls a building permit for work on a one- or two-family home, and Wisconsin has no roofing-specific license. Hudson Roofing Pros does this work, and when you book with us or anyone else, ask for proof of the credential and of insurance.
You can check a contractor's credential on the state's credential lookup. For a built-up roof on a shop or office, our commercial roofing service covers the work.

A new roof can go over a built-up roof on a home only if it is the roof's only layer and it is dry and sound. Two or more layers, or a soaked or deteriorated roof, must be torn off first.
