Homeowners across Grantsville call Big Toms Roofing because we do what we say โ show up on time, explain what we find in plain language, and stand behind every Roof Replacement job with a written warranty.

We built Big Toms Roofing to fix a problem every homeowner in Grantsville has run into: contractors who don't return calls, no-show for appointments, or pad the invoice once the tarp's already on the roof. Our Roof Replacement crews are local, licensed, and accountable โ every estimate is in writing before a single shingle gets pulled.
From a single missing shingle to a full tear-off, our Grantsville crews handle every stage of roofing work with the same attention to detail โ licensed, permitted, and cleaned up when we leave.
When a tree limb punches through decking or shingles peel back in a wind event, water gets in fast. We prioritize emergency calls in Grantsville above scheduled work, get a tarp on within hours, and document everything with photos for your insurance file.
When patching stops making financial sense, a full tear-off and reroof resets the clock on your home. We strip old material down to the deck, replace any rotten sheathing, install proper underlayment and ice-and-water protection, and finish with a manufacturer-certified shingle or metal system backed by a real warranty.
Commercial roofs fail differently than residential ones โ ponding water, seam separation, and membrane wear don't always show up until there's a leak on the sales floor below. Our Grantsville commercial division services TPO, EPDM, modified bitumen, and built-up roofing systems on retail, industrial, and multi-family properties.
Buying or selling a home in Grantsville? A pre-purchase roof inspection gives you real leverage in negotiations and peace of mind about what you're actually buying โ no guessing about remaining roof life.
A roof is only as good as the parts that direct water off it. We repair and replace step flashing, valley flashing, chimney flashing, and gutters that have pulled away from the fascia โ small jobs that prevent big leaks down the road.

Every one of these commitments exists because a Grantsville homeowner asked for it, complained about a competitor's lack of it, or we learned it the hard way.
You'll know the exact scope and cost in writing before work starts, and that number doesn't move unless you approve a change.
Local dispatch means less time waiting and more time getting your roof actually fixed.
Our installers hold current manufacturer certifications, which means your warranty stays intact and the work meets code.
If something about the finished work doesn't sit right with you, call us back and we'll make it right โ that's the deal.
