About Sullivan's Roofing

The roofer Harrow has trusted for generations.

Founded in 1986 by Andrew Sullivan, we've been one of Harrow's most trusted roofing companies for nearly four decades. We specialise in flat roofing and carry out all aspects of roofing work — from small repairs to complete new roofs — using only the best quality products.

We don't hard sell. We give straight, honest advice, show up when we say we will, and leave your property as tidy as we found it. If Andy gives you a price, that's the price.

What We Do

Every roofing need,
handled properly.

New Roofs

Full replacement roofs installed to the highest standard, using quality materials with long-term warranties. We'll give you an honest recommendation on the best system for your property.

Flat Roofs

Our speciality. All flat roofs carry a full 15-year guarantee. We use only the best products to ensure your flat roof performs reliably for decades to come.

Roof Repairs

Leaks, slipped tiles, damaged felt — no job too small. We'll diagnose the problem honestly and fix it right, without charging you for work you don't need.

Guttering

Blocked, leaking or broken gutters repaired and replaced. We survey the full run and make sure rainwater drains properly — protecting your walls and foundations.

UPVC Fascia & Soffit Boards

Rotten timber replaced with low-maintenance UPVC fascia and soffit boards. Clean, durable and finished to a consistently high standard.

Chimney & Pointing Work

Chimney stacks repointed, flashing replaced and lead work repaired. We'll stop the water getting in and make sure the whole structure is sound.

Customer Reviews

What our customers say.

★★★★★

Nick was professional from initial contact, had the knowledge to solve a tough roofing issue and was definitely not a time waster. When he says he'll be at your place at a certain time, he is. The cleanup after the roof was completed was done just as carefully as the workmanship itself. Highly recommended.

★★★★★

The most trusted roofer in Harrow. Been around since I was a kid! You might have to wait sometimes because he's very busy — but well worth it. I have peace of mind knowing the job will be done properly.

Rav K

★★★★★

Amazing service. I only texted him my address — he surveyed the property, repaired my guttering and texted me back with the bill. I didn't even have to wait around. As efficient as any builder could be. Would certainly recommend.

Anup D

★★★★★

Top man Andy. Received great reviews so used him for a roof fix. Polite and a good chap. Sorted the issues after the second visit. Recommend!

Hiten Shah
