frequently asked questions

FAQs about Flat Roof Installation

How is a flat roof installed?

Here’s a quick, high‑level rundown of how a flat roof is installed:

Prep & Decking: Remove old roofing down to a sound, sloped (1–2%) deck.
Repair or replace damaged decking.

Insulation & Underlayment: Fasten or adhere rigid insulation boards. Install a vapor barrier (if needed) and a layer of synthetic or felt underlayment.

Membrane Application: 

Built‑Up (BUR): Hot‑mop alternating asphalt and felt layers, top with gravel.
Single‑Ply (EPDM/TPO/PVC): Roll out membrane, adhere or mechanically fasten, seal seams (tape or heat‑weld).
Modified Bitumen: Torch‑down or cold‑adhere pre‑manufactured sheets, roll seams.

Flashings & Drainage: Install metal drip edge or termination bars at perimeters. Flash around penetrations (vents, skylights) with boots or custom metal. Fit internal drains or scuppers, sealing their flanges to the membrane.

Inspection & Maintenance: Check seams, fasteners, and drains for gaps. Keep roof clear of debris and inspect yearly (or after storms).

Can you install a flat roof yourself?

Yes, you can install a flat roof yourself using a Peel and Stick system, which is ideal for beginners due to its simplicity and minimal tool requirements. This DIY approach can save you significant costs compared to professional installation. Be sure to follow step-by-step guides or tutorials to ensure proper installation.

What is the cheapest option for a flat roof?

The cheapest option for a flat roof is generally roll roofing due to its low material and installation costs. However, keep in mind that while it’s budget-friendly, its lifespan is shorter compared to other roofing materials. Regular maintenance can help prolong its durability, making it a practical choice for short-term solutions.
