That flat section over the porch or addition isn’t built for shingles, and it’s usually the first part of the house to leak. We install EPDM membrane roofing on flat and low slope sections across Hudson and the surrounding area.
← Back to Roofing Installation & Replacement
You need EPDM if you have a flat or low slope section of roof, like a porch, addition, dormer, or outbuilding, where standard shingles were never a workable option. Watch for ponding water that never fully drains, seams that have started to lift, or a membrane that’s cracking or gone brittle. A failing membrane on a low slope section tends to leak quietly for a while before it shows up as a stain on the ceiling below, so catching it early matters.

We inspect the existing membrane and the deck underneath, check drainage and slope, and confirm the assembly method that fits the situation, whether that’s fully adhered or mechanically fastened. From there we install new underlayment and insulation as needed, lay the EPDM membrane, and seal every seam and penetration properly, since seams and edges are where most membrane roofs actually fail. We also address drainage so water moves off the roof instead of sitting on it.
Cost depends on the size of the section, the assembly method used, and whether insulation or deck repair is needed underneath. Pricing is transparent, and every EPDM project starts with a free, no obligation written estimate so you know the scope before we start.
We bring over 25 years of roofing and exterior experience to EPDM applications, and we hold Dwelling Contractor License and Dwelling Contractor Qualifier License credentials. We treat the low slope sections of your roof as part of the same system as the rest of the house, not an afterthought, and we’re available 24/7 if a membrane failure turns into an active leak.

According to the EPDM Roofing Association, roofing professionals report expected service lives ranging from about 25 years to more than 40 years depending on membrane thickness and how it’s installed, with some membranes still performing well past that. Proper installation and drainage design matter as much as the material itself.
Quality EPDM membranes stay flexible in extreme cold, which is part of why they’re a standard choice for low slope roofing in cold climates rather than cracking the way rigid materials can. The bigger risk in Wisconsin is standing water and ice at drains, which is why proper slope and drainage matter during installation.
Small tears and punctures in EPDM can often be repaired with the right patch materials rather than requiring full replacement. Whether a patch makes sense depends on the age and overall condition of the membrane, which we’ll assess honestly during an inspection.
Flat and low slope sections rely entirely on the membrane and seams to keep water out, with no steep pitch to help shed it quickly. Ponding water at drains, aged seams, and improper original installation are the most common causes we find on flat sections in this area.
In cold climates like Hudson, black EPDM is typically the better choice because it absorbs heat, which can help reduce heating costs and encourages snowmelt to drain rather than sit and refreeze. We’ll talk through the tradeoffs based on your specific roof during the estimate.
Don’t let a small leak on a flat section turn into interior damage.
