Do Roofers Work in the Rain?

If you’re a homeowner in Philadelphia or the surrounding suburbs, you know our weather has a mind of its own. You’ve scheduled your roof repair or replacement, and then you wake up to the sound of rain drumming against your window. It’s a familiar scene, and it always brings up the same urgent question: ‘Will the roofers still come?’

After 30 years in business and completing over 30,000 projects in Philadelphia and nearby regions, from Bensalem to Conshohocken, we at Discounted Roofing LLC have a clear answer. The short version is: typically, no. But the real-world explanation – the one that matters for protecting your home and your investment – is worth understanding. 

The Dangers of Working in the Rain

First, let’s talk about why a responsible roofer – like the teams we send to your home – will call off work when the rain starts falling. 

Think about it. A roof deck, especially an older one, is slippery when it’s dry. Now, add water, a layer of mud from foot traffic, and a steep pitch. You’ve got a recipe for a serious fall. The safety of our crew isn’t negotiable. We’re talking about people with families, not just employees. Sending someone up on a wet, steep-sloped roof is a risk we are simply not willing to take. 

Then there’s the quality of the work. Imagine trying to install asphalt shingles – the kind from our partners at GAF or Owens Corning – onto a damp deck. The adhesive strips on the shingles need heat and a dry surface to seal properly. If they’re installed wet, they might not seal at all. You’re left with a roof that looks great, but the first big wind could lift those shingles right off. It’s a foundational principle – a proper installation requires a dry start. 

And let’s not forget the materials themselves. Some roofing underlayments are designed to shed water during a brief shower, but they’re not meant for a full day’s work in a downpour. Saturated materials are a nightmare to work with, and they can trap moisture against the roof deck – the very thing we’re trying to prevent. That trapped moisture leads to rot, mold, and a whole new set of problems down the line. It’s a shortcut, and in our business, shortcuts always, always come back to haunt you. 

Instances When Roofers May Call Off Work

Safety and quality are the twin pillars of professional roofing. When rain threatens either one, we call a time-out. Here are the specific conditions that send our crews packing. 

Steep Slope Roof Projects

A wet, steep slope is incredibly dangerous. Asphalt shingles on a pitched roof become as slippery as an ice rink when wet. The risk of a serious fall is simply too high. Our team’s safety is our top priority. 

Installation of New Shingles

The adhesive strips on asphalt shingles from manufacturers like GAF and Owens Corning require heat and a dry surface to activate and seal properly. Applying them to a damp deck is a recipe for failure – those shingles might not seal at all, leaving your home vulnerable to wind damage and leaks. 

Saturated or Stormy Conditions 

A torrential downpour or a consistent, soaking rain makes any meaningful work impossible. Visibility is poor, materials get waterlogged, and the fundamental process of creating a watertight seal is compromised. 

The Conditional Yes: When Roofers May Continue Work

A downpour is a hard stop, almost every time. But there are some nuanced scenarios where you might still see activity on your property. It’s all about managing risk and making progress where we safely can. 

Emergency Tarping and Mitigation

We don’t wait for sunshine in emergency instances like a tree limb piercing your roof during a storm. We’ll start emergency repairs immediately by securing heavy-duty tarps to prevent further water intrusion into your home: a temporary solution until permanent repairs can be made in dry weather. 

Light, Intermittent Drizzle

A very light mist or a passing sprinkle is different from a steady rain. In these situations, our crew might continue with preparatory work, such as pre-cutting shingles in a garage or organizing materials, but will halt the moment the roof surface becomes dangerously wet. 

Non-Roofing and Ground-Based Tasks

Rain may not halt your entire project even if it complicates shingle work. Our team can continue to work safely for gutter repair and installation, site cleanup and organization, and interior inspections or drywall work not related to the active roof leak, and other ground-based tasks. 

Why You Should Avoid Roofing Work During Rainfall?

You might have noticed the promise made by some companies that they are ready to help you ‘rain or shine’. Be very, very wary of that promise. 

A roofer who is insisting on working through a rainstorm is cutting corners, and they’re cutting them on your most important asset – your home. The risks are just too high. 

Voided Warranties

This is a huge one. Manufacturers like Tamko and IKO have very specific installation requirements in their warranty guidelines.  We say this from direct experience: installing shingles on a wet deck is a surefire way to avoid that manufacturer’s warranty before it even starts. So, that ‘lifetime warranty’ they sold you is worthless. 

Hidden Moisture

As we mentioned before, trapping moisture is a death sentence for a roof structure. It can lead to soft, rotting wood that you won’t discover for months or even years, long after that fly-by-night crew has gone. 

Poor Adhesion

Shingles won’t seal. Flashing details won’t be watertight. The entire system is compromised from day one. 

At Discounted Roofing LLC, we partner with the best in the business for a reason. We believe in doing a job that lasts. That means respecting the materials, respecting the process, and most importantly, respecting your home enough to wait for the right conditions.
